Zadka-Peer S, Rosenbloom T. Targeted nudging for speeding behavior: The influence of interpersonal characteristics on responses to in-vehicle road nudges. ACCIDENT; ANALYSIS AND PREVENTION 2024; 204:107638. [PMID: 38815308 DOI: 10.1016/j.aap.2024.107638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 03/26/2024] [Accepted: 05/11/2024] [Indexed: 06/01/2024]
Abstract
Road carnage is one of the most fatal and expensive global issues today. Many solutions have been implemented to minimize it, but most are costly and unreliable. Therefore, in this study, nudges were used as a reliable and inexpensive tool to affect safe driving behavior which, in turn, may reduce road fatalities. To optimize the use of nudges, we suggested that responses to nudges - in a similar manner to responses to other stimuli - may vary by interpersonal characteristics, so that different nudges may lead to more accurate and reliable reactions in different sub-populations in a predictable manner. To test these assertions, we collected a sample of 200 participants, both men and women, ages 17.5 to 83 years. We measured different interpersonal characteristics that included both demographic information (e.g., age, gender, years with a driver's license) and different personality traits. We then assessed responses to nudges using a simulator that was specially designed for this study, in which participants are asked to adjust their speed as they see fit while they watched a video shot from a driver's perspective of the forward roadway. Over the course of the video, a different nudge was displayed for each subject and their response latency and speeds were recorded for further analysis. We were able to observe several interesting phenomena: responses to a reminder nudge and a negative reinforcement nudge were faster than responses to a social norm nudge. However, the latter showed a longer-term impact. The responses to the social norm interventions were also more variable, demonstrating that high neuroticism is linked to decreased response to social norm nudges, a picture that is repeated in men compared to women. Contrarily, conscientiousness was linked to a faster and more reliable response to the social norm nudge, and the gender effect was eliminated for men with high conscientiousness. Moreover, parenthood was found to increase the response to all nudges and was protective against the effects of high sensation-seeking, which led to more road violations. These findings may be tested using modern technology, which can facilitate the measurements of personal traits and verify the reliability of responses to nudges. Therefore, the current study suggests nudge personalization may be beneficial in improving the use of nudges on the road.

Abstract
Childhood trauma is a leading early adverse environment that increases psychopathological symptoms. Respiratory sinus arrhythmia (RSA) suppression to challenges as a marker of self-regulation is found to linearly moderate the link between early adverse experiences and psychopathological symptoms, but yielding mixed findings. The present study examined the relationships between childhood trauma and internalizing and externalizing symptoms via a 1.5-year longitudinal design and the quadratic moderation effect of RSA suppression on these relationships among adolescents. In November 2021 (T1), the final sample of 275 Chinese adolescents (Mage = 12.94, SDage = 0.79; 49.82% females) completed the short form of Childhood Trauma Questionnaire and the Achenbach Youth Self-Report-2001 and underwent a speech task during which their baseline RSA and stress exposure RSA were obtained. In June 2023 (T2), 251 adolescents completed the Achenbach Youth Self-Report-2001. Results showed that childhood trauma at T1 was positively correlated with internalizing and externalizing symptoms at T1 and T2. RSA suppression to stress quadratically moderated these associations, such that adolescents with moderate rather than higher or lower RSA suppression had the least internalizing and externalizing symptoms at T1 and T2 when exposed to childhood trauma. The findings suggest that moderate RSA suppression to stress as a marker of optimal vagal regulation buffers the risk of developmental psychopathology from early adverse experiences.

Abstract
BACKGROUND Opioid use disorder (OUD) is a heterogeneous disorder. However, there is a lack of deep phenotyping investigations focusing on important psychological constructs such as resilience that may impact OUD. The present study aimed to investigate the relationship between trait resilience and the five-factor model of personality (FFM) among individuals with opioid use disorder (OUD). We also explored whether the FFM and trait resilience form specific phenotypes associated with psychological functioning. METHODS This secondary analysis of an epigenetic study included participants of African ancestry (n = 72), an understudied population, who met DSM-5 criteria for OUD. Participants completed measures to assess personality traits, trait resilience, current and previous drug use, and psychological functioning (depression, anxiety, and stress). RESULTS Linear regression revealed a significant relationship between resilience (CD-RISC-25 score) and the FFM, R2 = 0.56, F(5,62) = 15.7, p<.001. Further, a two-cluster classification emerged as the optimal solution from the cluster analysis. Cluster 1 (n = 33, 45.8% of the sample) showed lower resilience (CD-RISC-25 score: M = 58.6, SD = 11.2) compared to Cluster 2 (n = 35, 48.6%; CD-RISC-25 score: M = 76.1, SD = 11.9). The "High-Resilience Cluster" (Cluster 2) was characterized by higher FFM traits of: Extraversion, Openness, Agreeableness, and Conscientiousness, and lower Neuroticism versus Cluster 1. Multivariate analysis of variance revealed statistically significant differences between the two resilience clusters concerning other psychological symptoms, Λ = 0.732, F(4, 50) = 7.05, p < 0.003. CONCLUSIONS These findings suggest associations between the FFM and trait resilience among individuals with OUD. Two distinct "resilience phenotypes" emerged, with high-resilience individuals displaying less stress, anxiety, and depressive symptoms. Results highlight the clinical importance of resilience as a potential target for intervention in people with OUD.

Abstract
BACKGROUND AND AIMS Adaptive physiological responses to stress have been suggested as a potential mechanism facilitating the association between extraversion and positive health outcomes. The present study examined the influence of extraversion on physiological reactivity and habituation to a standardized psychological stress task presented as two separate laboratory sessions approximately 48 days apart. METHODS The present study utilized data from the Pittsburgh Cold Study 3. Participants in the study (N = 213, mean age = 30.13, SD = 10.85 years; female = 42.3 %) completed a standardized stress testing protocol twice, at two separate laboratory sessions. The stress protocol consisted of a speech preparation period (5-minutes), a public specking task (5-minutes), and a mental arithmetic task with observation (5-minutes). Trait extraversion was assessed using 10-items from the international personality item pool (IPIP). Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR) and salivary cortisol (SC) were assessed throughout a baseline phase and the stress task phase. RESULTS Extraversion was statistically significantly associated with larger DBP and HR reactivity in response to the initial stress exposure, as well as greater habituation of DBP, MAP and HR on repeated stress exposure. No statistically significant associations emerged between extraversion and SBP responses, SC responses or self-reported state affective responses. CONCLUSION Extraversion is associated with greater cardiovascular reactivity, as well as pronounced cardiovascular habituation to acute social stress. These findings may indicate an adaptive response pattern amongst highly extraverted individuals and a potential mechanism leading to positive health outcomes.

Abstract
BACKGROUND AND AIMS Extraversion has been associated with positive physical health outcomes, with adaptive cardiovascular responses to stress being one potential physiological mechanism. The present study examined the influence of extraversion on both cardiovascular reactivity and cardiovascular habituation to an acute psychological stress task (Paced Auditory Serial Addition Test (PASAT)) in a sample of healthy undergraduate students. METHODS A sample of 467 undergraduate students completed the Big Five Inventory (BFI) to assess trait extraversion and attended a single stress testing session. The testing session included two identical stress-testing protocols, each consisting of a 10-minute baseline and 4-minute PASAT. Cardiovascular parameters including heart rate (HR), systolic/diastolic blood pressure (S/DBP) and mean arterial pressure (MAP) were recorded throughout the testing session. State measures of positive affect (PA) and negative affect (NA), as well as post task measures of self-reported stress were used to assess psychological experiences of the stress task. RESULTS Extraversion was significantly associated with lower self-reported stress in response to the initial stress exposure, but not the second stress exposure. Higher levels of extraversion were associated with lower SBP, DBP, MAP and HR reactivity in responses to both exposures to the stressor. However, no significant associations were observed between extraversion and cardiovascular habituation to recurring psychological stress. CONCLUSION Extraversion is associated with lower cardiovascular reactivity to acute psychological stress and this relationship persists upon repeated exposures to the same stressor. Cardiovascular responses to stress may indicate a potential mechanism facilitating the association between extraversion and positive physical health outcomes.

Abstract
BACKGROUND Early life adversity (ELA) increases the risk of cardiovascular diseases through dysregulation of cardiovascular stress responses manifested by either exaggerated or blunted reactivity. The catechol-O-methyltransferase (COMT) gene rs4680 polymorphism has been identified in gene-environment interaction (G×E) studies to explain individual differences in the effects of ELA on physiological stress responses. However, little is known about whether ELA interacts with COMT gene rs4680 polymorphism to affect cardiovascular responses to repeated stress exposures. OBJECTIVE The current study examined the associations between ELA and cardiovascular responses to repeated stress exposures, and the moderating role of COMT rs4680 polymorphism in these associations. METHODS The childhood trauma questionnaire (CTQ) was administered to 359 junior school students who underwent a two-successive stress exposures protocol with continuous cardiovascular monitoring [heart rate (HR) and systolic and diastolic blood pressure (SBP, DBP)] across four laboratory phases, and their saliva samples for deoxyribonucleic acid (DNA) genotyping were collected. RESULTS ELA was associated with blunted HR reactivity to the first and second stress exposures, blunted SBP reactivity to the first stress exposure, and attenuated SBP habituation to repeated stress exposures. Moreover, COMT rs4680 moderated these associations, such that the associations between ELA and blunted HR, SBP, and DBP reactivity to the first stress and disrupted DBP habituation to repeated stress exposures only existed in GA/AA genotype carriers but not in GG genotype carriers. CONCLUSIONS These findings suggest that the A allele of COMT rs4680 is vulnerable to the negative effects of ELA on the developmental dysregulation of stress physiological systems.

Abstract
Abstract. This study aimed to investigate whether and how avoidant personality disorder symptoms are related to cardiovascular reactivity to stress tasks with different levels of cognitive demands. The revised Chinese edition of the avoidant personality disorder subscale of Personality Diagnosed Questionnaire-4+ (PDQ-4+) was administered to 222 undergraduate students randomly assigned to psychological stress tasks (i.e., mental arithmetic tasks) with low, moderate, or high cognitive demands (manipulated by task difficulty), during which their physiological data were continuously collected. Results showed that avoidant personality disorder symptoms and cognitive demands of tasks interactively predicted systolic blood pressure (SBP) and diastolic blood pressure (DBP) reactivity. In specific, avoidant personality disorder symptoms were not associated with SBP reactivity under the low- and moderate-demand conditions and DBP reactivity under the low-demand condition but were associated with blunted SBP reactivity under the high-demand condition and blunted DBP reactivity under the moderate- and high-demand conditions. These findings indicate that the association between avoidant personality disorder symptoms and cardiovascular reactivity to psychological stress is contingent on the cognitive demands of tasks, which have potential implications for physical health.

Abstract
The 'reactivity hypothesis' has a long and fruitful history in health psychology and behavioural medicine, with elements of its thesis taken as core and others lost in the plethora of research on its utility as a theory of psychosomatic disease. One such thesis is that the underlying hemodynamic profile of the stress response may be particularly revealing when detailing the impact of psychological stress on the development of cardiovascular disease. This paper re-examines old ideas surrounding the hemodynamic profile of the stress response, asking why its health-predictive properties were never fully explored. Further, this paper reviews the evidence that a vascular profile of stress responding may be especially predictive of disease development, particularly in the case of hypertension. In addition, measurement of hemodynamic profile as well as its known psychosocial moderators are reviewed including how examination of patterns of cardiovascular-stress response adaptation may extend the field. This paper highlights that the extension of the reactivity hypothesis to include both hemodynamic profile and patterns of cardiovascular stress-response adaptation may hold much explanatory power in detailing the impact of how stress responding and stress tolerance promotes disease development.

Abstract
Test anxiety is a widespread and primarily detrimental emotion in learning and achievement settings. This research aimed to explore the autonomic nervous system (ANS) response patterns of test-anxious individuals in response to evaluative stress. By presenting a standard interview task, an evaluative scenario was effectively induced. Heart rate variability (HRV), a biomarker that can accurately reflect the ANS activity, was used to reflect the physiological responses of 48 high test-anxious subjects and 49 low test-anxious subjects. Results indicate that: (1) both groups show a significantly increased emotional arousal in the evaluative scenario; (2) high test-anxious individuals show a significantly decreased emotional pleasantness in the evaluative scenario, whereas low test-anxious individuals show no significant changes; (3) both groups show a significantly increased low-frequency HRV; (4) high test-anxious individuals show a significantly decreased high-frequency HRV and root mean square of successive heartbeat interval differences (RMSSD), whereas low test-anxious individuals remain stable. These findings suggest that high test-anxious individuals display an increased sympathetic nervous system (SNS) activity and a decreased parasympathetic nervous system (PNS) activity in response to evaluative stress, while low-anxious individuals display an increased SNS activity and a stable PNS activity in response to evaluative stress.

Abstract
Childhood maltreatment as an early-life stress leads to cardiovascular stress response dysregulation manifested by either exaggerated or blunted stress responses. However, little is known how childhood maltreatment affects cardiovascular response habituation to recurrent stress, which implicated in the long-term health effects of chronic stress. The scale of Childhood Trauma Questionnaire (CTQ) was administered to 192 healthy undergraduates who underwent continuous cardiovascular monitoring [heart rate (HR), blood pressure (BP), cardiac output (CO) and total peripheral resistance (TPR)] while facing two consecutive psychosocial stress exposures (public speaking tasks). Results showed that childhood maltreatment was negatively associated with HR and CO reactivity to the first stress exposure and HR reactivity to the second stress exposure. Even after controlling for depression symptoms, both high and low childhood maltreatment groups (upper and lower 27% of total CTQ scores) exhibited HR and CO response habituation to repeated stress exposures, but high childhood maltreatment group showed blunted HR and CO reactivity to the first stress exposure compared with low childhood maltreatment group. These findings suggest that the observed cardiovascular response habituation to repeated stress following initial blunted (i.e., inadequate) reactivity among individuals with high childhood maltreated experiences might be maladaptive, which would lead to cardiovascular disease risk.

Abstract
Research and theory have shown a link between heart rate reactivity during cognitive testing and extraversion in younger adults; however, similar work has not been conducted with older adults. This study was designed to explore age and extraversion-related differences in within-person heart rate (HR) reactivity during two working memory tasks of varying difficulty using a multi-level modeling approach. Across 570 total within-person assessments of continuous HR monitoring, 28 younger adults (M = 19.76, SD = 1.15) and 29 older adults (M = 71.19, SD = 6.63) were administered two working memory tasks (backward digit span and n-back). There were no age differences in reactivity during the backward digit span. However, similar to previous findings, on the more difficult n-back task, younger adults low in extraversion showed a trend toward higher HR reactivity than young adults high in extraversion. Interestingly, the older adults showed the opposite pattern in that lower extraversion older adults were less reactive than the higher extraversion older adults who showed the steepest increase in HR. The HR increase of the older adults high in extraversion may be an indication of higher engagement in this more difficult task. Individual differences in extraversion need to be taken into account when administering working memory tasks in older adults.

Is stressor-evoked cardiovascular reactivity a pathway linking positive and negative emotionality to preclinical cardiovascular disease risk? Psychophysiology 2020; 58:e13741. [PMID: 33278305 DOI: 10.1111/psyp.13741] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 11/06/2020] [Accepted: 11/10/2020] [Indexed: 11/28/2022]
Abstract
Stressor-evoked cardiovascular reactivity, trait positive emotionality, and negative emotionality are all associated with cardiovascular disease. It is unknown, however, whether cardiovascular reactivity may constitute a pathway by which trait positive or negative emotionality relates to disease risk. Accordingly, this study modeled the cross-sectional relationships between trait positive and negative emotionality, stressor-evoked cardiovascular reactivity, and severity of a subclinical vascular marker of cardiovascular risk, carotid artery intima-media thickness (CA-IMT). The sample consisted of healthy, midlife adults free from clinical cardiovascular disease (N = 286; ages 30-54; 50% female). Trait positive and negative emotionality were measured by three questionnaires. Heart rate and blood pressure reactivity were assessed across three stressor tasks. CA-IMT was assessed by ultrasonography. Latent factors of positive and negative emotionality, blood pressure reactivity, heart rate reactivity, and CA-IMT were created using structural equation modeling. Greater negative emotionality was marginally associated with more CA-IMT (β = .21; p = .049), but lower blood pressure reactivity (β = -.19; p = .03). However, heightened blood pressure (β = .21; p = .03), but not heart rate reactivity (β = -.05; p = .75), associated with greater CA-IMT. Positive emotionality was uncorrelated with cardiovascular reactivity (blood pressure: β = -.04; p = .61; heart rate: β = .16; p = .11) and CA-IMT (β = .16; p = .07). Although trait negative emotionality associates with a known marker of cardiovascular disease risk, independent of positive emotionality, it is unlikely to occur via a stressor-evoked cardiovascular reactivity pathway.

OBJECTIVE The underlying mechanisms for linking Type D personality to cardiovascular stress reactivity remain unknown. The present study explored the possible mediating role of cognitive appraisals of stress and/or motivational levels involved in stress in the association between Type D personality and cardiovascular stress reactivity. DESIGN Cross-sectional. METHODS Chinese version of Type D Scale-14 was administered to 154 undergraduate students who underwent psychosocial stress during which the physiological data were continuously monitored, and cognitive appraisals indexed by a ratio of perceived stress demands to perceived personal resources and motivational levels engaged in stress indexed by self-reported stress task engagement were immediately assessed after the stress exposure. RESULTS Results indicated that Type D personality was related to blunted HR, SBP, and DBP reactivity to stress. Self-reported stress task engagement mediated the relation between Type D personality and blunted cardiovascular stress reactivity. The mediation effect of cognitive appraisals on this link was non-significant. CONCLUSIONS These findings suggest that motivational disengagement in the psychosocial stress task might be an important pathway linking Type D personality to blunted cardiovascular stress reactivity.

Abstract
ARMARIO, A, J. Labad and R. Nadal. Focusing attention on biological markers of acute stressor intensity: empirical evidence and limitations. NEUROSCIENCE AND BIOBEHAVIORAL REVIEWS. The availability of biological markers that objectively quantify stress is a highly relevant issue. However, experimental evidence suggests that most physiological changes elicited by emotional stressors do not reflect their intensity and are not useful for this purpose. Thus, we review experimental evidence in animals and humans about the putative validity of neuroendocrine and sympathetic/parasympathetic variables to measure stress. Plasma levels of some hormones (e.g. ACTH, glucocorticoids, prolactin and catecholamines) have been found to reflect, at least under certain conditions, the intensity of emotional stressors in animals and probably in humans. However, the temporal resolution of hormone changes is insufficient to reflect the very dynamic psychological processes taking place while experiencing stressors. Cardiovascular parameters (e.g. heart rate and blood pressure) have much better temporal resolution but their validity as markers of stressor intensity either in animals or humans is problematic. Skin conductance and pupil dilation appear to be promising. Additional and more systematic studies are needed to demonstrate the actual validity of stress-induced physiological changes to quantify stress.

Abstract
Recent research has suggested that diminished, as well as elevated reactivity to acute psychological stress is maladaptive. These differences in stress reactions have been hypothesized to relate to the Big Five personality traits, which are said to be biologically-based and stable across adulthood; however, findings have been inconclusive. This study sought to replicate the findings of the largest study conducted to date (Bibbey et al., 2013), with a sample of participants from the Midlife in the United States Study (MIDUS), aged between 35 and 84 years (M = 56.33, SD = 10.87). Participants (N = 817) undertook a standardized, laboratory-based procedure during which their cardiovascular and neuroendocrine reactivity to acute stress was measured. In contrast to Bibbey et al. (2013), associations between neuroticism and blunted reactivity did not withstand adjustment for confounding variables. Further, following adjustment for multiple tests, no significant positive association between agreeableness and HR reactivity was observed. Methodological differences between the studies, which may account in part for the contrasting findings, are discussed. Further conceptual replication research is needed to clarify associations between the Big Five personality traits and stress reactivity, across the lifespan.

Abstract
The present study examined the potential moderating role respiratory sinus arrhythmia (RSA) plays in the relationship between parental marital conflict and adolescents' internalizing problems. To examine this issue, data were collected from 330 adolescents (13-14 years, 182 boys). The Chinese version of the Achenbach Youth Self-Report-2001 and the Chinese version of the Children's Perception of Interparental Conflict were used to assess the adolescents' internalizing problems and their perceptions of parental marital conflict. To obtain RSA data, electrocardiogram monitoring was performed on the adolescents at baseline and during a series of stress tasks (watching a film clip depicting marital conflict, a mental arithmetic task, and a speech task). The results indicated that baseline RSA and RSA reactivity to the film clip moderated the relationship between parental marital conflict and internalizing problems in early adolescents. The moderating effect of baseline RSA supported the BSCT hypothesis. Specifically, adolescents with low baseline RSA have both the highest and lowest levels of internalizing problems, depending on the level of marital conflict. In contrast, adolescents with high levels of baseline RSA have moderate levels in internalizing problems, regardless of the level of marital conflict they experience. Similarly, high marital conflict was related to internalizing problems for adolescents with less RSA suppression or RSA augmentation but not for those with greater RSA suppression. This effect was specific to stress related to marital conflict, as RSA reactivity to the mental arithmetic task and speech task did not moderate the relationship between marital conflict and internalizing problems. These findings suggest that certain profile of parasympathetic nervous activity is a risk factor for internalizing problems particularly for those who experience high-conflict environments.
