Being highly sensitive person negatively impacts on cognitive and psychosocial fatigue in multiple sclerosis patients: A cross-sectional, monocenter study. Mult Scler Relat Disord 2024; 90:105769. [PMID: 39067188 DOI: 10.1016/j.msard.2024.105769] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 07/02/2024] [Accepted: 07/12/2024] [Indexed: 07/30/2024]
Abstract
BACKGROUND Fatigue is a common symptom in Multiple Sclerosis (MS), but its determinants are not clarified yet. Sensory processing sensitivity (SPS) is a personality trait characterized by enhanced sensitivity towards endogenous and exogenous stimuli, and higher attention toward minimal stimuli, resulting in overarousal and fatigue. OBJECTIVE to evaluate the association between SPS and fatigue in MS patients. METHODS 192 consecutive MS patients (age of 43.3 ± 12.1 years; females 67.2 %; median EDSS of 2.5 (0 - 7)) underwent clinical (EDSS, age, gender), cognitive (BICAMS, Trial Making Test [TMT]), psychosocial (Beck Anxiety Inventory [BAI], Beck Depression Inventory [BDI], Modified Fatigue Impact Scale [MFIS]) and sensitivity evaluation (Highly Sensitive Person [HSP]Scale). Patients were classified as HSP if the score was greater than 14. A stepwise regression model was applied to explore association between SPS and MFIS total scores and sub-scores, by accounting for age, gender, education, EDSS, Cerebral FS scores, TMT-Part A and part B scores, BAI, BDI, and Pittsburgh Sleep Quality Index (PSQI). RESULTS Total HSP was 17.2 ± 6.8 and 129 patients (67 %) were classified as highly sensitive persons (HSP). HSP patients were more female patients (p = 0.02) with a longer disease duration (p = 0.03). HSP people showed higher total MFIS score (27.6 ± 20.6 vs 13.2 ± 14.1, p < 0.001), higher physical MFIS score (p < 0.001), higher cognitive MFIS score (p < 0.001), higher psychosocial MFIS score (p < 0.001) vs non-HSP patients. Higher total MFIS was associated with SPS trait (coeff. 6.9, p = 0.006). Specifically, SPS trait was associated with higher cognitive MFIS (coeff. 5.3, p < 0.001) and higher psychosocial MFIS (coeff. 0.7, p = 0.02). CONCLUSION SPS was associated with fatigue. Since SPS could be easily and quickly assessed in clinical settings, SPS could unveil a higher propensity of a patient toward fatigue occurrence over the disease course and could provide hints for possible preventive cognitive behavior therapy.

Harrold A, Keating K, Larkin F, Setti A. The association between sensory processing and stress in the adult population: A systematic review. Appl Psychol Health Well Being 2024.

Abstract
There is emerging empirical evidence indicating that differences in self-reported sensory processing may be associated with differences in levels of stress in the adult populations. Understanding how sensory processing relates to stress is of clinical relevance, given the well-established impact of stress on physical health, mental health and well-being. Although several studies have examined the association between sensory processing and stress in adult populations, no published reviews have systematically summarised and synthesised these findings. We aimed to fill this gap by conducting a systematic review to synthesise the available evidence examining the association between self-reported sensory processing and self-reported measures of stress in the adult population. The review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA-S) checklist. Twenty studies were included in the final review. Quality assessment was conducted with the Mixed Methods Appraisal Tool. Overall, the evidence is strong for an association between differences in sensory processing and self-reported stress in adults. This association was found across a range of populations and measures of stress, in cross-sectional studies. The most commonly used measure of sensory processing was the Highly Sensitive Person Scale, which was consistently moderately associated with a range of measures of stress. The quality of the included studies was generally good, with most meeting four or five out of five criteria. Longitudinal studies are lacking. There is strong evidence for a cross-sectional association between sensory processing and stress in an adult population. Further research, in particular longitudinal studies and studies including clinical populations, would be of benefit in order to establish causality.

Abstract
While interest grows in investigating sensory processing sensitivity (SPS), few studies have employed objective behavioural measures to directly explore the underlying attentional processing. The present study utilised two modified versions of the Emotional Attention Networks Test Integration (E-ANTI) to investigate whether and how emotion interacts with three attentional networks associated with SPS when emotion information was target-irrelevant (Experiment 1) and target-relevant (Experiment 2), respectively. Both experiments involved four manipulated within-subject factors: Signal (tone vs. no-tone), Cue Validity (valid vs. invalid), Flanker Congruency (congruent vs. incongruent), and Emotion (fearful vs. happy). Linear mixed models were employed, and three attentional networks were successfully captured in both experiments. In Experiment 1, we observed that as SPS increased, the difference in reaction time between valid and invalid cue conditions decreased, especially in incongruent trials. Participants rated fearful faces as more arousing than happy faces as SPS increased. In Experiment 2, we found that slow responding to fearful faces reduced as SPS increased, particularly in incongruent trials. The observed effects related to SPS in both experiments were particularly pronounced in incongruent conditions, suggesting that SPS may modulate attentional processes in high-conflict situations. Overall, higher SPS may be associated with increased cautiousness in conflict contexts.

Abstract
Sensory Processing Sensitivity (SPS) is a temperament trait rooted in biology, and is distinguished by heightened awareness, emotional responsiveness, and sensitivity to environmental stimuli. In this study, we aimed to enable the assessment of SPS within Spanish-speaking populations. To achieve this, we translated, adapted, and validated the Sensory Processing Sensitivity Questionnaire (SPSQ), which offers a comprehensive evaluation of SPS, encompassing both positive and negative aspects of the trait. Participants were 1,004 (844 females, mean age 37) mainly from Chile (964), and 40 were from other Spanish-speaking regions. Confirmatory factor analysis, utilizing the diagonally weighted least squares method, was applied to validate the internal structure of the Spanish version of the SPSQ (S-SPSQ). Fit indices such as GFI, CFI, TLI, RMSEA, and SRMR were scrutinized. Reliability assessment utilized Cronbach's alpha and McDonald's Omega. Three models were examined: Model I (six factors) displayed robustness, Model II (six factors plus a general factor) did not show substantive improvement, and Model III (Higher Order and Bifactor) excelled in fit while balancing complexity and representation, thus validating the findings of the original SPSQ and indicating similar reliability coefficients. The study offers a balanced perspective on SPS and contributes to cross-cultural validation of an SPS instrument which may facilitate research and guide personalized therapeutic interventions, thus enhancing outcomes for highly sensitive persons.

Abstract
All individuals on planet earth are sensitive to the environment, but some more than others. These individual differences in sensitivity to environments are seen across many animal species including humans, and can influence personalities as well as vulnerability and resilience to mental disorders. Yet, little is known about the underlying brain mechanisms. Key genes that contribute to individual differences in environmental sensitivity are the serotonin transporter, dopamine D4 receptor and brain-derived neurotrophic factor genes. By synthesizing neurodevelopmental findings of these genetic factors, and discussing them through the lens of mechanisms related to sensitive periods, which are phases of heightened neuronal plasticity during which a certain network is being finetuned by experiences, we propose that these genetic factors delay but extend postnatal sensitive periods. This may explain why sensitive individuals show behavioral features that are characteristic of a young brain state at the level of sensory information processing, such as reduced filtering or blockade of irrelevant information, resulting in a sensory processing system that 'keeps all options open'.

Abstract
Sensory modulation is critical for interacting with the physical and social environment. When sensory input from the environment is not properly perceived and modulated, it may elevate arausability, avoidant behavior, impair function and wellbeing. Sensory modulation difficulties (SMD) are mainly reported during childhood and are related to neurodevelopmental conditions such as Attention-Deficit Hyperactivity Disorder (ADHD). SMD in adulthood further deteriorate function and emotional status, hence should be screened and treated. Nonetheless, relevant measures of SMD for adults are limited. This study aims to establish the psychometric properties of the "SENSE" - Sensory and Behavioral Modulation Questionnaire for adults. Based on theoretical/clinical knowledge the SENSE measures sensitivity/arousability, habituation and avoidance. After establishing content and face validity, 663 participants aged 18-65 completed a sociodemographic and health questionnaire, the Adult ADHD Scale-5 (ASRS-5), the SENSE and the Highly Sensitive Person Scale (HSPS). Factor analysis approved the determination of SENSE scales. Medium- high internal consistency was found. SENSE discriminated between adults with/without ADHD and correlated with HSPS scores, confirming concurrent validity. CONCLUSIONS: SENSE has good psychometric properties and may be feasible for screening sensory-behavioral modulation difficulties in adults. Studies should further examine SENSE applicability to clinical populations.

Abstract
Sensory processing sensitivity (SPS) is a personality trait described in humans and dogs that mediates how individuals are affected by experiences. It involves being aware of subtle stimuli, high emotional intensity and empathy, and deeper processing of information. Recognizing individuals scoring higher in SPS is likely to help better diagnose, treat, and prevent both psychological (behavioral) and physical problems, leading to increased welfare and quality of life of the animal and its surroundings.

Abstract
Sensory processing sensitivity (SPS), linked with a penchant for the arts and creativity, exerts its bivalent influences, contingent on context, on individuals' health-related outcomes. But little is known about how it interacts with creative self-concept (CSC). Focusing on the role of SPS, this study identified risk and protective factors of resilience among artistically inclined individuals from middle to later life during the coronavirus 2019 (COVID-19) restriction period and examined the interaction effect between SPS and CSC on depression. Two stages of analyses were pursued. Stage 1 identified factors associated with resilience by using regression and profile analyses on data from 224 anonymized respondents from middle to third age (Mage = 54.08, SD = 10.08, range = 40-84) with diverse disciplinary backgrounds in visual arts. Stage 2 examined the influence of SPS on the relationship between CSC and depression. SPS, lack of peer support of shared interests in the arts, and depression emerged as risk factors associated with lower levels of resilience. The profiles of SPS components among the relatively high and low resilience groups were found to be divergent. The effects of CSC on depression were contingent upon SPS, controlling for neuroticism. The findings call for future research to examine the differential correlational patterns among the SPS components and neuroticism across different populations. The risk/protective factors and patterns found in this study provide directions for research in SPS and applied work to support artistically inclined individuals from middle to later life.

Abstract
Two individual-difference theories focus on sensory sensitivity: one emanating from psychology-sensory-processing-sensitivity (SPS); and one from occupational therapy-sensory processing theory (SP). Each theory is coupled with its measure: the highly-sensitive-person scale (HSPS) and the adolescent adult sensory profile (ASP). The constructs of both theories were claimed to be independent of neuroticism. To assess the convergence of these measures, we recruited participants from a general population and a Facebook Group dedicated to people high in SPS. The participants, N = 1,702 M age = 26.9 (66.7% female), answered the HSPS, ASP, and neuroticism questionnaires. We subjected the HSPS and the APS to exploratory graph analysis. To assess the divergence of these measures from neuroticism, we performed meta-analyses. We also used a subsample obtained in an unrelated study, N = 490, to correlate HSPS and APS with the Big Five and additional measures. The results suggested that (a) the latent structure of these measures conforms to the theories only partially, (b) some of the sub-scales of these two measures correlated highly, r = 0.63, but low enough to suggest divergence, (c) both differentially predict membership in a Facebook group, and (d) both are not isomorphic with neuroticism. We concluded that HSPS primarily measures the emotional reaction to sensory stimulation, whereas ASP the behavioral reactions. We offer shorter yet reliable measures for both theories.

Abstract
Previous research using functional MRI identified brain regions associated with sensory processing sensitivity (SPS), a proposed normal phenotype trait. To further validate SPS, to characterize it anatomically, and to test the usefulness in psychology of methodologies that assess axonal properties, the present study correlated SPS proxy questionnaire scores (adjusted for neuroticism) with diffusion tensor imaging (DTI) measures. Participants (n = 408) from the Human Connectome Project were studied. Voxelwise analysis showed that mean- and radial diffusivity correlated positively with SPS scores in the right and left subcallosal and anterior-ventral cingulum bundle, and the right forceps minor of the corpus callosum, all frontal cortex areas generally underlying emotion, motivation, and cognition. Further analyses showed correlations throughout medial frontal cortical regions in the right and left ventromedial prefrontal cortex, including the superior longitudinal fasciculus, inferior fronto-occipital fasciculus, uncinate, and arcuate fasciculus. Fractional anisotropy was negatively correlated with SPS scores in white matter (WM) of the right premotor/motor/somatosensory/supramarginal gyrus regions. Region of interest (ROI) analysis showed small effect sizes (- 0.165 to 0.148) in WM of the precuneus and inferior frontal gyrus. Other ROI effects were found in the dorsal-, ventral visual pathways and primary auditory cortex. The results reveal that in a large group of participants, axonal microarchitectural differences can be identified with SPS traits that are subtle and in the range of typical behavior. The results suggest that the heightened sensory processing in people who show that SPS may be influenced by the microstructure of WM in specific cortical regions. Although previous fMRI studies had identified most of these areas, the DTI results put a new focus on brain areas related to attention and cognitive flexibility, empathy, emotion, and first levels of sensory processing, as in primary auditory cortex. Psychological trait characterization may benefit from DTI methodology by identifying influential brain systems for traits.

Abstract
Sensory processing sensitivity is described as a personality trait associated with a high sensitivity to environmental and social stimuli. It has been assumed that about 15–20% of the total population can be described as highly sensitive. The concept states that those individuals represent a higher sensitivity to subtle stimuli, thereby exhibiting a different somatic sensation. Here we aim to test the assumption that the brain’s sensory perception is different in individuals with high sensory processing sensitivity. We used a German version of the Highly Sensitive Person scale to measure sensory processing sensitivity. Furthermore, we assessed the Big Five personality dimensions and trait empathy (using IRI). To test the hypothesis that the brain’s handling of sensory information is different in individuals with high sensory-processing sensitivity, we scanned participant’s brain activity with functional magnetic resonance imaging (fMRI) while they were touched by an experimenter’s hand. Results showed positive correlations of sensory processing sensitivity with neuroticism, openness, and empathy. Introversion was not a significant predictor. Neuroimaging data demonstrated that sensory processing sensitivity (controlled for associated personality dimensions) was not related to primary or secondary somatosensory BOLD responses, but positively associated with BOLD activity in left posterior insular cortex. Based on these results we conclude that sensory processing sensitivity seems to represent insula-mediated affective touch. We discuss these results with previous studies reporting an engagement of the insula in individuals with high sensory processing sensitivity.

Abstract
This study examined the relationship between sensory processing sensitivity and psychological stress reactivity in 69 healthy Japanese university students. The Japanese version of the Highly Sensitive Person Scale and the Japanese version of the Adolescent/Adult Sensory Profile were used for subjective assessment. The Galvanic skin response was measured as an objective measure of stress responses while the participants were completing the Stroop task. The Wilcoxon signed-rank test, the Spearman rank correlation coefficient, and the Mann−Whitney U test were conducted for data analysis. The results demonstrated that there was no significant correlation between the Japanese version of the Highly Sensitive Person Scale and Galvanic skin response. However, there was a marginal trend toward significance between low registration in the Japanese version of the Adolescent/Adult Sensory Profile and Galvanic skin response (rs = 0.231, p < 0.10; rs = 0.219, p < 0.10), suggesting that self-rated sensitivity was not necessarily associated with objective measures. These results indicate that sensory processing sensitivity analyses require the consideration of the traits and characteristics of the participants and multifaceted evaluations using a sensitivity assessment scale other than the Japanese version of the Highly Sensitive Person Scale.

Brain Sci 2022; 12:brainsci12050641.

Abstract
Many concepts of the human personality are based on assumptions about underlying physiological processes. The most prominent example is probably the concept of extraversion introduced by H.J. Eysenck decades ago. However, more recent approaches also propose that personality traits may be reflected by physiological processes. For example, empathic personality dimensions have been linked to tactile perception, suggesting that individuals with higher tactile sensitivity are also more empathetic to the sensations of others. Another recent example is the concept of sensory processing sensitivity, which has been linked to enhanced primary sensory processing. However, the exact relationship between tactile abilities and personality is still unclear, thus the current study aims to test whether different personality dimensions affect the performance in a tactile acuity task. Tactile abilities of healthy participants were tested with tactile 2-point-thresholds on the hands. Personality dimensions were examined with respect to empathy, sensory processing sensitivity, and the Big Five. Results revealed that empathy, but not sensory processing sensitivity, was associated with tactile performance. We conclude that the ability to feel with someone else seems to be linked to the perception of our own body. Thus, the sense of touch may play an important role for empathy. We discuss explanations of these results and highlight possible implications of our findings.

Abstract
Sensory Processing Sensitivity (SPS) is a common, heritable, and evolutionarily conserved trait, describing inter-individual differences in responsiveness and a more cautious approach to novel stimuli. It is associated with increased activation of brain regions involved in awareness, integration of sensory information, and empathy during processing of emotional faces. Furthermore, SPS is related to better performance in a visual detection task. Even though SPS is conceptualized to be closely related to traits characterized by pausing before acting, no study to date has assessed the relation between SPS and inhibitory control in a behavioral inhibition task. The present study fills this gap by investigating how SPS influences individual performance on two different antisaccade paradigms including emotional face stimuli. In addition, we assessed self-reported mood, anxiety, and depressiveness. Results showed that SPS was related to faster processing speed on the emotional, but not the classic antisaccade paradigm. Moreover, SPS predicted inhibitory control speed above mood and depressiveness. Our results provide evidence that higher SPS participants show superior inhibitory abilities, especially during the processing of emotional stimuli. This is in line with earlier findings showing better performance in a visual detection task as well as increased brain activation during emotional face processing.

Abstract
BACKGROUND Sensory processing sensitivity (SPS) is a biologically based temperament trait associated with enhanced awareness and responsivity to environmental and social stimuli. Individuals with high SPS are more affected by their environments, which may result in overarousal, cognitive depletion, and fatigue. METHOD We examined individual differences in resting-state (rs) brain connectivity (using functional MRI) as a function of SPS among a group of adults (M age = 66.13 ± 11.44 years) immediately after they completed a social affective "empathy" task. SPS was measured with the Highly Sensitive Person (HSP) Scale and correlated with rs brain connectivity. RESULTS Results showed enhanced rs brain connectivity within the ventral attention, dorsal attention, and limbic networks as a function of greater SPS. Region of interest analyses showed increased rs brain connectivity between the hippocampus and the precuneus (implicated in episodic memory); while weaker connectivity was shown between the amygdala and the periaqueductal gray (important for anxiety), and the hippocampus and insula (implicated in habitual cognitive processing). CONCLUSIONS The present study showed that SPS is associated with rs brain connectivity implicated in attentional control, consolidation of memory, physiological homeostasis, and deliberative cognition. These results support theories proposing "depth of processing" as a central feature of SPS and highlight the neural processes underlying this cardinal feature of the trait.

Abstract
This study examined whether components of sensory processing sensitivity (SPS) could moderate the effect of perceived stress on depressive symptoms and its neural substrates. In this study, 244 participants (181females) reported on their SPS, perceived stress, and experienced depressive symptoms, and subsequently underwent a resting-state functional magnetic resonance imaging (RS-fMRI) to explore the neural basis of their SPS characteristics. Behavioral results showed that, compared with individuals low in EOE (i.e., ease of excitation, a sub-dimension of SPS), those high in EOE were more likely to report depressive symptoms under stress. The VBM analysis indicated that EOE was significantly positively correlated with gray matter (GM) volumes of right cerebellum and negatively correlated with GM volumes of right dorsal anterior cingulate cortex (right dACC). Moreover, GM volumes of the two areas moderated the relation between stress and depression. These findings collectively suggest that the structural abnormalities in these regions might account for simulating and experiencing intense emotional reactions frequently among individuals with high EOE. Thus, the accumulation of these negative emotions in reaction to stress may lead to higher probabilities of experiencing depressive symptoms. Taken together, present study shed light on how stress interacted with sensory processing sensitivity to predict depression from the neural perspective.

Abstract
Sensory Processing Sensitivity (SPS) is a personality trait in humans characterised by a tendency to process information deeply, to be easily overstimulated, and to have strong emotional responses and an enhanced sensitivity to subtle stimuli. A trait similar to SPS has recently been identified in dogs ("canine Sensory Processing Sensitivity", cSPS). In children, this trait interacts with parenting factors to influence emotional and mental development, which in turn are linked to behaviour problems. Paralleling these findings in humans, we demonstrate that cSPS interacts with owner personality and use of aversive communication to influence the likelihood of behaviour problems in dogs. More behaviour problems were reported for more highly sensitive dogs per se, when there was a relative mismatch between owner and dog personality, and when use of "negative punishment" was reported. These findings indicate that a dog's personality might moderate how an individual is affected by environmental factors, particularly owner personality and communication style, emphasising the importance of considering individuality in prevention, development and treatment of behaviour problems in dogs.

Abstract
Background: Adolescence and young adulthood are periods of increased substance use, with insecurely attached individuals at greater risk of abusing substances. With recent evidence linking insecure attachment with sensory sensitivity, and evidence that both are linked with higher levels of distress, there is a need to consider these variables in relation to substance use in a sample of young adults. Methods: A convenience sample of 223 young adults (18-24 years) completed self-report measures of attachment, sensory sensitivity, use of various substances (e.g. alcohol, legal and illegal drugs, cigarettes, energy drinks), and distress. Correlation, t-test, and regression/mediation analyses were conducted. Results: Sensory sensitivity was positively correlated with insecure attachment. Anxious attachment was related to problematic substance use, frequent cigarette use, and misuse of prescribed medications. Avoidant attachment was associated with frequent use of cigarettes and energy drinks. Sensory sensitivity, attachment anxiety, and attachment avoidance each had significant indirect effects on problematic substance use, mediated by increased levels of distress. Conclusions: Sensory sensitivity and attachment insecurity both appear to impact problematic substance use in young adults through elevated levels of distress. Findings support consideration of sensory- and attachment-informed interventions with this population.

Abstract
AIM Dentistry is a stressful and exhausting profession with high levels of burnout. Sensory processing sensitivity (SPS) is a basic personality trait characterised by a gradient of sensitivity to both internal and external stimuli, including social and emotional cues. In this study, the influence of SPS on burnout and professional quality of life among Israeli dentists was analysed. METHODS Two-hundred and forty-three Israeli dentists responded to questionnaires that collected information on their SPS and professional quality of life (burnout, satisfaction at work and level of secondary traumatic stress), as well demographic variables, professional specialisation and workload. RESULTS Linear regression analyses showed that burnout can be predicted by the three aspects of SPS (ease of excitation, low sensory threshold and aesthetic sensitivity; 32% of the variance). Additionally, the same three aspects of SPS also predicted dentists' satisfaction at work (24% of the variance). Ease of excitation and low sensory threshold, but not aesthetic sensitivity, predicted dentists' reaction to their patients' stress and trauma (23% of the variance). CONCLUSIONS Sensory processing sensitivity can serve as a tool to identify dentists who are prone to develop burnout and whose professional quality of life can be adversely affected by their profession.

Abstract
Abstract. High sensitivity is an individual disposition to perceive and process external and internal stimuli more intensely than the average population. For measuring high sensitivity, Aron and Aron (1997) developed a unidimensional self-report questionnaire. However, Smolewska, McCabe, and Woody (2006) fitted a model with three correlated factors: ease of excitation, aesthetic sensitivity, and low sensory threshold. Both models were questioned by Evans and Rothbart (2008) who postulated a two-factor structure: negative affect and orienting sensitivity. Nonetheless, the studies presented so far are based on small samples and did not address the issues of the ordinal data and measurement invariance. We presented the first study that compared all postulated models, thereby taking the ordinal data into account, and evaluated the measurement invariance. We adopted the High Sensitive Person (HSP)-Scale for German-speaking populations and found that a three-factor model provided the best fit. However, we excluded 13 items because of their low factor loadings or high intercorrelations. The revised HSP-Scale fit a three-factor model. Furthermore, we could establish a high level of measurement invariance (strict invariance), indicating equality of loadings, thresholds, and residual variances across sex. The scale showed good psychometric properties and high test-retest reliability. Finally, relationships with psychological symptoms were presented.

Abstract
It has been hypothesized that an increased sensitivity to the surroundings, can leave some individuals vulnerable to experience the environmental stress of winter more overwhelming, thus leading to a greater risk of Seasonal Affective Disorder (SAD). However, the association between trait Sensory Processing Sensitivity (SPS) and SAD is not known. We therefore aimed to investigate: 1)cross-seasonal group differences in trait SPS, in 31 individuals with SAD compared to 30 age-, gender- and education-matched healthy controls, and 2)the association between trait SPS in remitted phase (summer) and depression severity in symptomatic phase (winter) in individuals with SAD. All participants completed the Highly Sensitive Person Scale, as a measure of SPS, and the Major Depression Inventory in summer and in winter, using a longitudinal and seasonally counterbalanced design. In both remitted and symptomatic phase, individuals with SAD exhibited higher trait SPS compared to healthy controls, which for individuals with SAD was heightened during depression in winter. Notably, when averaged across season, about 25% of the individuals with SAD display high-sensitivity whereas this is only the case for 5% of the healthy controls. In addition, higher trait SPS in summer was associated with more severe SAD symptoms in winter. Our findings suggest that those with SAD are more likely to score high on SPS and that high SPS may be a vulnerability marker related to more severe SAD symptomatology.

Abstract
Parenting styles vary in levels of both warmth and control, with evidence that type of parenting behavior is linked with social-emotional and other developmental outcomes for children. There are well-established associations between adult attachment and parenting styles. Given emerging evidence that people with different attachment patterns vary in how they receive and modulate sensory information, there are potential implications for parenting which have rarely received research attention. This cross-sectional study investigates the links between parenting style and parental sensory sensitivity, and the possible mediating role of parental sensory sensitivity in the relationship between adult attachment and parenting styles. A convenience sample of 155 parents of children aged 4-12 years old completed an online survey measuring: adult attachment (Experiences in Close Relationships-Modified 16-item Scale), sensory sensitivity (Highly Sensitive Persons Scale-Shortened Version), and parenting styles (Parenting Styles and Dimensions Questionnaire). Correlation, regression and mediation analyses were conducted. Analyses revealed that parents who reported more attachment insecurity also reported higher levels of parental sensory sensitivity, and more authoritarian and/or permissive (non-optimal) parenting styles. Parental sensory sensitivity was found to fully mediate the relationship between attachment avoidance and permissive parenting, and to partially mediate the relationship between attachment anxiety and both authoritarian and permissive parenting. This study represents the first quantitative evidence for associations between parental sensory sensitivity and parenting styles, and the mediating effect of parental sensory sensitivity on the known relationship between attachment insecurity and parenting. Awareness of a parent's level of sensory sensitivity, in addition to his/her attachment style, may assist in developing effective strategies to meet both the parent's and child's needs and support the parent-child relationship.

Abstract
Creativity, meant as the ability to produce novel, original and suitable ideas, has received increased attention by research in the last years, especially from neuroaesthetics and social neuroscience. Besides the research conducted on the neural correlates of such capacities, previous work tried to answer the question of whether it is possible to enhance creativity through cognitive and neural stimulation. In particular, transcranial direct current stimulation (tDCS) has been applied to increase neuronal excitability in those areas related to creativity. However, being a complex construct that applies to a huge variety of situations, available results are often confusing and inconsistent. Thus, in the present critical review, after selecting original research articles investigating creativity with tDCS, results will be reviewed and framed according to the different effects of tDCS and its underlying mechanisms, which can be defined as follows: the promotion of self-focused attention; the disruption of inhibiting mechanisms; the enhancement of creative thinking; the promotion of artistic enactment. Finally, a theoretical perspective, the creative on/off model, will be provided to integrate the reported evidence with respect to both anatomical and functional issues and propose a cognitive explanation of the emergence of creative thinking.

Abstract
According to empirical studies and recent theories, people differ substantially in their reactivity or sensitivity to environmental influences with some being generally more affected than others. More sensitive individuals have been described as orchids and less-sensitive ones as dandelions. Applying a data-driven approach, we explored the existence of sensitivity groups in a sample of 906 adults who completed the highly sensitive person (HSP) scale. According to factor analyses, the HSP scale reflects a bifactor model with a general sensitivity factor. In contrast to prevailing theories, latent class analyses consistently suggested the existence of three rather than two groups. While we were able to identify a highly sensitive (orchids, 31%) and a low-sensitive group (dandelions, 29%), we also detected a third group (40%) characterised by medium sensitivity, which we refer to as tulips in keeping with the flower metaphor. Preliminary cut-off scores for all three groups are provided. In order to characterise the different sensitivity groups, we investigated group differences regarding the Big Five personality traits, as well as experimentally assessed emotional reactivity in an additional independent sample. According to these follow-up analyses, the three groups differed in neuroticism, extraversion and emotional reactivity to positive mood induction with orchids scoring significantly higher in neuroticism and emotional reactivity and lower in extraversion than the other two groups (dandelions also differed significantly from tulips). Findings suggest that environmental sensitivity is a continuous and normally distributed trait but that people fall into three distinct sensitive groups along a sensitivity continuum.

Abstract
OBJECTIVE Sensory processing sensitivity (SPS) is a recently proposed construct that refers to a genetically influenced tendency to more strongly and deeply process a variety of information. The aim of the study was to examine whether SPS is associated with an autoimmune disease such as type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS Participants were 128 adolescents (62 with T1D and 66 comparisons [without autoimmune disease]) and their parents who completed the Highly Sensitive Person Scale (HSPS) questionnaire, assessing SPS level. RESULTS Higher levels of SPS were found in the T1D group than in the comparison group. Furthermore, the frequency of SPS trait was significantly higher in the T1D group than in the comparison group. CONCLUSIONS T1D is associated with higher levels of SPS. Hence, there is a need to develop interventions, treatments, and care focused on the needs of T1D patients with SPS temperament, aimed at better treatment adherence. Furthermore, longitudinal research is needed to evaluate whether SPS is a risk factor in the development of T1D.

J Exp Child Psychol 2017; 163:53-68.

Abstract
When interacting with other people, both children's biological predispositions and past experiences play a role in how they will process and respond to social-emotional cues. Children may partly differ in their reactions to such cues because they differ in the threshold for perceiving such cues in general. Theoretically, perceptual sensitivity (i.e., the amount of detection of slight, low-intensity stimuli from the external environment independent of visual and auditory ability) might, therefore, provide us with specific information on individual differences in susceptibility to the environment. However, the temperament trait of perceptual sensitivity is highly understudied. In an experiment, we tested whether school-aged children's (N=521, 52.5% boys, Mage=9.72years, SD=1.51) motor (facial electromyography) and affective (self-report) reactivities to dynamic facial expressions and vocalizations is predicted by their (parent-reported) perceptual sensitivity. Our results indicate that children's perceptual sensitivity predicts their motor reactivity to both happy and angry expressions and vocalizations. In addition, perceptual sensitivity interacted with positive (but not negative) parenting behavior in predicting children's motor reactivity to these emotions. Our findings suggest that perceptual sensitivity might indeed provide us with information on individual differences in reactivity to social-emotional cues, both alone and in interaction with parenting behavior. Because perceptual sensitivity focuses specifically on whether children perceive cues from their environment, and not on whether these cues cause arousal and/or whether children are able to regulate this arousal, it should be considered that perceptual sensitivity lies at the root of such individual differences.

Abstract
In humans, the personality dimension 'sensory processing sensitivity (SPS)', also referred to as "high sensitivity", involves deeper processing of sensory information, which can be associated with physiological and behavioral overarousal. However, it has not been studied up to now whether this dimension also exists in other species. SPS can influence how people perceive the environment and how this affects them, thus a similar dimension in animals would be highly relevant with respect to animal welfare. We therefore explored whether SPS translates to dogs, one of the primary model species in personality research. A 32-item questionnaire to assess the "highly sensitive dog score" (HSD-s) was developed based on the "highly sensitive person" (HSP) questionnaire. A large-scale, international online survey was conducted, including the HSD questionnaire, as well as questions on fearfulness, neuroticism, "demographic" (e.g. dog sex, age, weight; age at adoption, etc.) and "human" factors (e.g. owner age, sex, profession, communication style, etc.), and the HSP questionnaire. Data were analyzed using linear mixed effect models with forward stepwise selection to test prediction of HSD-s by the above-mentioned factors, with country of residence and dog breed treated as random effects. A total of 3647 questionnaires were fully completed. HSD-, fearfulness, neuroticism and HSP-scores showed good internal consistencies, and HSD-s only moderately correlated with fearfulness and neuroticism scores, paralleling previous findings in humans. Intra- (N = 447) and inter-rater (N = 120) reliabilities were good. Demographic and human factors, including HSP score, explained only a small amount of the variance of HSD-s. A PCA analysis identified three subtraits of SPS, comparable to human findings. Overall, the measured personality dimension in dogs showed good internal consistency, partial independence from fearfulness and neuroticism, and good intra- and inter-rater reliability, indicating good construct validity of the HSD questionnaire. Human and demographic factors only marginally affected the HSD-s suggesting that, as hypothesized for human SPS, a genetic basis may underlie this dimension within the dog species.

Abstract
Current research supports the notion that the apparently innate trait Sensory Processing Sensitivity (SPS) may act as a modulator of development as function of the environment. Interestingly, the common serotonin transporter linked polymorphic region (5-HTTLPR) does the same. While neural mechanisms underlying SPS are largely unknown, those associated with the 5-HTTLPR have been extensively investigated. We perform a comparative analysis of research findings on sensory processing facets associated with the trait and polymorphism to: 1. detect shared phenotypes and frame a hypothesis towards neural mechanisms underlying SPS; 2. increase the understanding of 5-HTTLPR-associated behavioral patterns. Trait and polymorphism are both associated with differential susceptibility to environmental stimuli; additionally, both involve 1. having stronger emotional reactions, 2. processing of sensory information more deeply, 3. being more aware of environmental subtleties, and 4. being easily overstimulated. We discuss neural mechanisms and environmental conditions that may underlie these four facets. Besides urging the actual assessment of the link between the two, the conclusions of our analyses may guide and focus future research strategies.

Abstract
OBJECTIVE To better understand the ways in which adult attachment, sensory processing, and distress may be interrelated in healthy adults. METHOD A cross-sectional study design was used with a convenience sample of 116 healthy participants who completed questionnaires before participating in a cold pressor pain-inducement task. RESULTS Attachment anxiety was significantly positively correlated with sensory sensitivity as measured using the Highly Sensitive Persons Scale and the Sensory Profile and with distress (i.e., stress, anxiety, and depression). Associations between attachment anxiety and both sensory sensitivity variables were lost when controlling for stress. Attachment avoidance was correlated only with sensory sensitivity measured using the Sensory Profile, and this relationship was retained when controlling for stress. Neither the attachment nor the stress variables were associated with sensation seeking. CONCLUSION Findings suggest that developing active coping approaches to deal with sensory sensitivities may be a valuable way to minimize distress. Recommendations for future research are provided.

Abstract
A swiftly growing volume of literature, comprising both human and animal studies and employing both observational and experimental designs, has documented striking individual differences in neurobiological sensitivities to environmental circumstances within subgroups of study samples. This differential susceptibility to social and physical environments operates bidirectionally, in both adverse and beneficial contexts, and results in a minority subpopulation with remarkably poor or unusually positive trajectories of health and development, contingent upon the character of environmental conditions. Differences in contextual susceptibility appear to emerge in early development, as the interactive and adaptive product of genetic and environmental attributes. This paper surveys what is currently known of the mechanisms or mediators of differential susceptibility, at the levels of temperament and behavior, physiological systems, brain circuitry and neuronal function, and genetic and epigenetic variation. It concludes with the assertion that differential susceptibility is inherently grounded within processes of biological moderation, the complexities of which are at present only partially understood.

Abstract
Sensory processing sensitivity (SPS) is an intrinsic personality trait whose genetic and neural bases have recently been studied. The current study used a neural mediation model to explore whether resting-state brain functions mediated the effects of dopamine-related genes on SPS. 298 healthy Chinese college students (96 males, mean age = 20.42 years, SD = 0.89) were scanned with magnetic resonance imaging during resting state, genotyped for 98 loci within the dopamine system, and administered the Highly Sensitive Person Scale. We extracted a “gene score” that summarized the genetic variations representing the 10 loci that were significantly linked to SPS, and then used path analysis to search for brain regions whose resting-state data would help explain the gene-behavior association. Mediation analysis revealed that temporal homogeneity of regional spontaneous activity (ReHo) in the precuneus actually suppressed the effect of dopamine-related genes on SPS. The path model explained 16% of the variance of SPS. This study represents the first attempt at using a multi-gene voxel-based neural mediation model to explore the complex relations among genes, brain, and personality.

Abstract
BACKGROUND Theory and research suggest that sensory processing sensitivity (SPS), found in roughly 20% of humans and over 100 other species, is a trait associated with greater sensitivity and responsiveness to the environment and to social stimuli. Self-report studies have shown that high-SPS individuals are strongly affected by others' moods, but no previous study has examined neural systems engaged in response to others' emotions. METHODS This study examined the neural correlates of SPS (measured by the standard short-form Highly Sensitive Person [HSP] scale) among 18 participants (10 females) while viewing photos of their romantic partners and of strangers displaying positive, negative, or neutral facial expressions. One year apart, 13 of the 18 participants were scanned twice. RESULTS Across all conditions, HSP scores were associated with increased brain activation of regions involved in attention and action planning (in the cingulate and premotor area [PMA]). For happy and sad photo conditions, SPS was associated with activation of brain regions involved in awareness, integration of sensory information, empathy, and action planning (e.g., cingulate, insula, inferior frontal gyrus [IFG], middle temporal gyrus [MTG], and PMA). CONCLUSIONS As predicted, for partner images and for happy facial photos, HSP scores were associated with stronger activation of brain regions involved in awareness, empathy, and self-other processing. These results provide evidence that awareness and responsiveness are fundamental features of SPS, and show how the brain may mediate these traits.

Abstract
Individual differences in the capacity for information processing in complex tasks can be predicted from both personality and temperament that derive from both the biological and social substrates of human development and behavior. If there are cultural differences in brain structure and function that govern information processing, then two different cultures may show biologically based temperamental differences in sensitivity to stimulation (e.g., Pavlov’s Strength of the Nervous System) which in turn may predict individual differences in capacity for tolerating environmentally determined stimulus overloads. We examined the relationship between biologically based measures of Pavlovian Temperament (Strength of Excitation, Inhibition, and Mobility) and an individual differences measure consisting of five dimensions of capacity for tolerating information load. Both direct and indirect effects of country of origin on capacity for information processing were tested in a mediated path analytic model in which Pavlovian Excitation, Inhibition, and Mobility were hypothesized to mediate the relationship between culture and self-reported information processing capacities.

Abstract
Evolutionary psychology has seen the majority of its success exploring adaptive features of the mind believed to be ubiquitous across our species. This has given rise to the belief that the adaptationist approach has little to offer the field of differential psychology, which concerns itself exclusively with the ways in which individuals systematically differ. By framing the historical origins of both disciplines, and exploring the means through which they each address the unique challenges of psychological description and explanation, the present article identifies the conceptual and theoretical problems that have kept differential psychology isolated not only from evolutionary psychology, but from explanatory approaches in general. Paying special attention to these conceptual problems, the authors review how these difficulties are being overcome by contemporary evolutionary research, and offer instructive suggestions concerning how differential researchers (and others) can best build upon these innovations.

Abstract
The highly sensitive trait present in animals, has also been proposed as a human neurobiological trait. People having such trait can process larger amounts of sensory information than usual, making it an excellent attribute that allows to pick up subtle environmental details and cues. Furthermore, this trait correlates to some sort of giftedness such as higher perception, inventiveness, imagination and creativity. We present evidences that support the existance of key neural connectivity between the mentioned trait, higher sensory processing sensitivity, introversion, ectomorphism and creativity. The neurobiological and behavioral implications that these biomarkers have in people living in developing rural areas are discussed as well.

Abstract
The aim of this review is to highlight an emerging field: the neuroscience of culture. This new field links cross-cultural psychology with cognitive neuroscience across fundamental domains of cognitive and social psychology. We present a summary of studies on emotion, perspective-taking, memory, object perception, attention, language, and the self, showing cultural differences in behavior as well as in neural activation. Although it is still nascent, the broad impact of merging the study of culture with cognitive neuroscience holds mutual distributed benefits for multiple related fields. Thus, cultural neuroscience may be uniquely poised to provide insights and breakthroughs for longstanding questions and problems in the study of behavior and thought, and its capacity for integration across multiple levels of analysis is especially high. These findings attest to the plasticity of the brain and its adaptation to cultural contexts.

Abstract
This article reviews the literature on sensory processing sensitivity (SPS) in light of growing evidence from evolutionary biology that many personality differences in nonhuman species involve being more or less responsive, reactive, flexible, or sensitive to the environment. After briefly defining SPS, it first discusses how biologists studying animal personality have conceptualized this general environmental sensitivity. Second, it reviews relevant previous human personality/temperament work, focusing on crossover interactions (where a trait generates positive or negative outcomes depending on the environment), and traits relevant to specific hypothesized aspects of SPS: inhibition of behavior, sensitivity to stimuli, depth of processing, and emotional/physiological reactivity. Third, it reviews support for the overall SPS model, focusing on development of the Highly Sensitive Person (HSP) Scale as a measure of SPS then on neuroimaging and genetic studies using the scale, all of which bears on the extent to which SPS in humans corresponds to biological responsivity.

Contributions of dopamine-related genes and environmental factors to highly sensitive personality: a multi-step neuronal system-level approach. PLoS One 2011; 6:e21636. [PMID: 21765900 PMCID: PMC3135587 DOI: 10.1371/journal.pone.0021636] [Citation(s) in RCA: 37] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2011] [Accepted: 06/04/2011] [Indexed: 11/19/2022] Open
Abstract
Traditional behavioral genetic studies (e.g., twin, adoption studies) have shown that human personality has moderate to high heritability, but recent molecular behavioral genetic studies have failed to identify quantitative trait loci (QTL) with consistent effects. The current study adopted a multi-step approach (ANOVA followed by multiple regression and permutation) to assess the cumulative effects of multiple QTLs. Using a system-level (dopamine system) genetic approach, we investigated a personality trait deeply rooted in the nervous system (the Highly Sensitive Personality, HSP). 480 healthy Chinese college students were given the HSP scale and genotyped for 98 representative polymorphisms in all major dopamine neurotransmitter genes. In addition, two environment factors (stressful life events and parental warmth) that have been implicated for their contributions to personality development were included to investigate their relative contributions as compared to genetic factors. In Step 1, using ANOVA, we identified 10 polymorphisms that made statistically significant contributions to HSP. In Step 2, these polymorphism's main effects and interactions were assessed using multiple regression. This model accounted for 15% of the variance of HSP (p<0.001). Recent stressful life events accounted for an additional 2% of the variance. Finally, permutation analyses ascertained the probability of obtaining these findings by chance to be very low, p ranging from 0.001 to 0.006. Dividing these loci by the subsystems of dopamine synthesis, degradation/transport, receptor and modulation, we found that the modulation and receptor subsystems made the most significant contribution to HSP. The results of this study demonstrate the utility of a multi-step neuronal system-level approach in assessing genetic contributions to individual differences in human behavior. It can potentially bridge the gap between the high heritability estimates based on traditional behavioral genetics and the lack of reproducible genetic effects observed currently from molecular genetic studies.

Abstract
Cultural neuroscience is an interdisciplinary field of research that investigates interrelations among culture, mind and the brain. Drawing on both the growing body of scientific evidence on cultural variation in psychological processes and the recent development of social and cognitive neuroscience, this emerging field of research aspires to understand how culture as an amalgam of values, meanings, conventions, and artifacts that constitute daily social realities might interact with the mind and its underlying brain pathways of each individual member of the culture. In this article, following a brief review of studies that demonstrate the surprising degree to which brain processes are malleably shaped by cultural tools and practices, the authors discuss cultural variation in brain processes involved in self-representations, cognition, emotion and motivation. They then propose (i) that primary values of culture such as independence and interdependence are reflected in the compositions of cultural tasks (i.e. daily routines designed to accomplish the cultural values) and further (ii) that active and sustained engagement in these tasks yields culturally patterned neural activities of the brain, thereby laying the ground for the embodied construction of the self and identity. Implications for research on culture and the brain are discussed.
