Attachment and emotional memory: investigating the source and extent of avoidant memory impairments

Modulation of maintenance and processing in working memory by negative emotions

Previous research has shown that working memory processes are affected by emotions. However, it is not clear if both components - maintenance and processing of information - are modulated by emotion. Since emotion is intimately related to attention, we focused on attentional maintenance in working memory. In a previous study, using a complex span task, we showed that processing emotionally negative information reduced maintenance of neutral information in working memory. The objective of the present study was first to replicate the results of our previous study and second to investigate whether maintaining emotional information would affect processing of neutral information. In Experiment 1, young adults were asked to remember a series of five letters each followed by images, either negative or neutral, to be categorized. In Experiment 2, participants were required to memorize a series of five images, either negative or neutral, each followed by digits to be categorized. In order to focus on attentional maintenance, in both experiments the tasks were performed under continuous articulatory suppression. In Experiment 1, longer processing times were observed for emotional stimuli than neutral ones, and lower recall of series of letters when negative stimuli were processed. In Experiment 2, higher memory performance was observed for negative images than neutral ones and longer processing times of digits when a series of negative stimuli was maintained. Overall, our results show that emotion impacts both processing and attentional maintenance in working memory. This is consistent with models of working memory suggesting an attentional trade-off between maintenance and processing.

Associations of peripheral blood DNA methylation and estimated monocyte proportion differences during infancy with toddler attachment style

Attachment is a motivational system promoting felt security to a caregiver resulting in a persistent internal working model of interpersonal behavior. Attachment styles are developed in early social environments and predict future health and development outcomes with potential biological signatures, such as epigenetic modifications like DNA methylation (DNAm). Thus, we hypothesized infant DNAm would associate with toddler attachment styles. An epigenome-wide association study (EWAS) of blood DNAm from 3-month-old infants was regressed onto children's attachment style from the Strange Situation Procedure at 22-months at multiple DNAm Cytosine-phosphate-Guanine (CpG) sites. The 26 identified CpGs associated with proinflammatory immune phenotypes and cognitive development. In post-hoc analyses, only maternal cognitive-growth fostering, encouraging intellectual exploration, contributed. For disorganized children, DNAm-derived cell-type proportions estimated higher monocytes -cells in immune responses hypothesized to increase with early adversity. Collectively, these findings suggested the potential biological embedding of both adverse and advantageous social environments as early as 3-months-old.

Polygenic risk for traumatic loss-related PTSD in US military veterans: Protective effect of secure attachment style

OBJECTIVES

To examine whether attachment style moderates the relationship between polygenic risk scores (PRS) for posttraumatic stress disorder (PTSD) re-experiencing (PTSD_REX) symptoms and the severity of and positive screen for traumatic loss-related PTSD.

METHODS

Data were analysed from 631 US veterans who endorsed 'unexpected death of a loved one' as their 'worst' traumatic event. Multivariable models evaluated the association between PRS for PTSD_REX, attachment style, and their interaction in predicting severity and positive screen for PTSD. A gene enrichment analysis was conducted to identify possible molecular mechanisms underlying the association between PTSD_REX PRS and PTSD.

RESULTS

PTSD_REX PRS (β = 0.17; odds ratio [OR] = 1.85), attachment style (β= -0.33; OR = 0.14), and PTSD_REX PRS × attachment style interaction (β= -0.12; OR = 0.53) were significant predictors of the severity and positive screen for PTSD. The most significant gene set detected was the gene ontology (GO) cellular component podosome set (GO:0002102, p < 3.95 × 10^-5).

CONCLUSIONS

Having a secure attachment style may help mitigate polygenic risk for developing traumatic loss-related PTSD in US veterans. Podosomes, which are implicated in inflammatory and neuroplasticity processes, may contribute to the genetic liability to developing loss-related PTSD. Psychological treatments targeting attachment security may help mitigate increased polygenic risk for loss-related PTSD in this population.

The Study of Security Priming on Avoidant Attentional Biases: Combining Microsaccadic Eye-Movement Measurement With a Dot-Probe Task

Microsaccades are small fixational eye movements that have shown to index covert attentional shifts. The present experiment combined microsaccades with performance measures from a dot-probe task to study influences of attachment security priming on the attentional biases of individuals high in attachment avoidance. Security priming is an experimental manipulation aimed at boosting felt security. Using a randomized, mixed design, we measured differences in attentional vigilance toward angry and neutral faces as a function of priming (neutral vs. secure) and attachment avoidance. Individuals high in avoidance habitually tend to withdraw from, or otherwise dismiss, emotionally salient stimuli. Here, we operationalized attentional withdrawal based on both task performance in the dot-probe task and microsaccadic movements. In addition, unlike previous studies where priming salience for the individual participant has been unclear, we used a standardized narrative method for attachment script assessment, securing an indication of how strongly each participant was primed. Dot-probe data significantly captured the link between avoidance and attentional disengagement, though from all facial stimuli (angry and neutral). Although microsaccadic movements did not capture avoidant attentional disengagement, they positively correlated to dot-probe data suggesting measurement convergence. Avoidance was associated with weaker security priming and no overall effect of priming on attention was found, indicating a need for further exploration of suitable priming methods to bypass avoidant deactivation. Our results provide a first indication that, as an implicit looking measure, microsaccadic movements can potentially reveal where early attention is directed at the exact moment of stimulus presentation.

Self-defining memories-Narrative features in relation to adaptive and maladaptive personality traits (replication and extension of Blagov & Singer, 2004)

OBJECTIVE

Self-defining memories (SDMs) are units of life-story analysis, whose features resemble elements from narrative identity's factorial structure. To bridge narrative-identity and personality-trait domains, we conducted a replication and extension of prior research.

METHOD

We linked four SDM features - affect, specificity, meaning making, and content - to the Big Three trait domains of personality and psychopathology in a small sample that was well-powered for multilevel modeling (133 participants, 1330 SDMs).

RESULTS

Affect SDM affect correlated with indices of Positive Emotionality and Negative Emotionality, and narrative themes of contamination were associated with Negative Emotionality. Specificity SDM specificity vs. overgenerality related to Constraint and Negative Emotionality indices, lending support to the executive dysfunction and emotional disorder theories of overgeneral autobiographical memory. (Tests of the avoidance thesis of overgeneral memory were inconclusive.) Meaning making Explicit meaning making in SDMs reflected adaptive personality. It moderated (or buffered) the link between SDMs' affect and chronic emotional distress. Content The links between SDM content and traits suggest that SDMs reflect personal goals, whose fulfillment or frustration relate to psychological health.

CONCLUSIONS

This research serves replication purposes as well as the purpose of connecting two major domains of personality: narrative identity and adaptive and maladaptive traits.

I Need a Doctor, Call Me a Doctor: Attachment and the Evaluation of General Practitioners before and during the COVID-19 Pandemic

Attachment is a system of threat regulation, and insecure (anxious and avoidant) attachment orientations are important individual difference antecedents to the cognitive and affective attributions of trait inferences. However, little is known about how threat-related contexts, such as the current COVID-19 pandemic, influence attachment-related socio-cognitive schemas. Using an experimental research design across two independent samples of 330 (pre-onset of COVID-19) and 233 (post-onset of COVID-19) participants, we tested whether attachment orientations influenced general practitioner (GP) ratings and selection differently pre- and post-onset of the COVID-19 pandemic. We found that during the COVID-19 pandemic, when presented with only negative information signals, avoidant individuals attributed positive ratings to GPs, with differing ratings as the number of positive signals increased. Differences between pre- and post-onset of the COVID-19 pandemic were less pronounced with regards to positive signals. We discuss these results in line with signal detection theory (SDT) and provide practical implications in response to our findings.

Adult attachment dimensions: Differential effects on physiological and subjective response during the recollection of childhood memories

The aim of this study was to explore the relationship between adult attachment dimensions and emotional response induced by the recall of potentially painful memories from childhood. A convenience sample of 100 women responded to an interview that focused on experiences with their caregivers during childhood, and a control interview, in counterbalanced order. Skin conductance level (SCL), heart rate (HR), heart rate variability (HRV), as well as subjective distress measures were collected. Results from generalized linear mixed model indicated that individuals high in avoidance showed a pattern of SCL increase from baseline that persisted during rest phases regardless of the topic addressed. Attachment dimensions did not affect HR, neither alone nor interacting with the interviews content, whereas baseline resting vagal tone was the most important factor. No attachment dimensions effects were observed on subjective measures of emotion; the time-varying vagal tone during rest phases did not moderate their relationships. Limited evidence was observed in support of the hypothesis that attachment Avoidance and Anxiety are associated with distinct physiological regulation profiles during the recall of potentially painful childhood memories.

Investigating the role of attachment orientation during emotional face recognition: An event-related potential study

We recorded event-related potentials (ERPs) while anxious and avoidant participants performed an emotional face recognition task featuring happy and angry faces. The avoidant attachment individuals were more accurate on angry trials, whereas anxious attachment individuals were more accurate on happy trials. FN400 amplitude was larger in the anxious attachment group than in the avoidant attachment group. Both groups produced larger N170 amplitudes in response to angry faces. However, happy faces evoked shorter N170 latencies in the anxious attachment group while angry faces evoked shorter N170 latencies in the avoidant group. Our results demonstrate that the processing of emotional stimuli differs between individuals with anxious and avoidant attachment styles. These differences start at early stages of stimulus processing and yield perceptual biases in the two attachment orientations. This appears to underlie differences in the later stage of recognition of emotional stimuli.

Stimulating the left dorsolateral prefrontal cortex improves the memory representation of threats among individuals with high avoidant attachment

Prior research has suggested that individuals with high avoidant attachment may demonstrate a vigilant attentional bias and selective attentional avoidance towards attachment-related negative information (threat information). Similarly, some evidence suggests that impairment of hot working memory (WM) or emotional-related WM occurs in highly avoidant individuals. Moreover, functional MRI studies have demonstrated that the less-activated left dorsolateral prefrontal cortex (L-DLPFC) is related to the impairment of cognitive control for threat stimuli in individuals with high avoidant attachment. Therefore, in the present study, the causal role of the L-DLPFC on hot WM presentation was investigated by the high-definition transcranial direct current stimulation (HD-tDCS) technique, and cognitive control for internal mental representations in WM was measured by the Internal Shift Task (IST). The results showed that the highly avoidant participants performed faster on the emotional IST than low avoidant participants in the sham condition. In the emotional IST, highly avoidant participants were slower after receiving anodal HD-tDCS than in the sham condition. Moreover, the switching cost of the emotional IST was significantly smaller in the highly avoidant group than low avoidant group under the sham HD-tDCS condition. Interestingly, in the emotional IST, the switching cost of highly avoidant individuals was significantly greater in the anodal stimulation group than the sham stimulation group. Conversely, the switching cost of low avoidant individuals was significantly smaller with anodal stimulation than for sham stimulation. The findings indicate that anodal HD-tDCS over the L-DLPFC can effectively enhance the ability of memory representation towards threat information in highly avoidant individuals. This study extends causal research by showing that the L-DLPFC is an important brain region for hot WM representations.

Attachment anxiety benefits from security priming: Evidence from working memory performance

The present study investigates the relationship between the attachment dimensions (anxious vs. avoidance) and the cognitive performance of individuals, specifically whether the attachment dimensions would predict the working memory (WM) performance. In the n-back task, reflecting the WM capacity, both attachment related and non-attachment related words were used. Participants were randomly assigned into two groups that received either the secure or the neutral subliminal priming. In the secure priming condition, the aim was to induce sense of security by presenting secure attachment words prior to the n-back task performance. In neutral priming condition, neutral words that did not elicit sense of security were presented. Structural equation modeling revealed divergent patterns for attachment anxiety and avoidance dimensions under the different priming conditions. In neutral priming condition, WM performance declined in terms of capacity in the n-back task for individuals who rated higher levels of attachment anxiety. However in the secure priming condition, WM performance was boosted in the n-back task for individuals who rated higher levels of attachment anxiety. In other words, the subliminal priming of the security led to increased WM capacity of individuals who rated higher levels of attachment anxiety. This effect, however, was not observed for higher levels of attachment avoidance. Results are discussed along the lines of hyperactivation and deactivation strategies of the attachment system.

Priming the Secure Attachment Schema Affects the Emotional Face Processing Bias in Attachment Anxiety: An fMRI Research

Our study explored how priming with a secure base schema affects the processing of emotional facial stimuli in individuals with attachment anxiety. We enrolled 42 undergraduate students between 18 and 27 years of age, and divided them into two groups: attachment anxiety and attachment secure. All participants were primed under two conditions, the secure priming using references to the partner, and neutral priming using neutral references. We performed repeated attachment security priming combined with a dual-task paradigm and functional magnetic resonance imaging. Participants’ reaction times in terms of responding to the facial stimuli were also measured. Attachment security priming can facilitate an individual’s processing of positive emotional faces; for instance, the presentation of the partner’s name was associated with stronger activities in a wide range of brain regions and faster reaction times for positive facial expressions in the subjects. The current finding of higher activity in the left-hemisphere regions for secure priming rather than neutral priming is consistent with the prediction that attachment security priming triggers the spread of the activation of a positive emotional state. However, the difference in brain activity during processing of both, positive and negative emotional facial stimuli between the two priming conditions appeared in the attachment anxiety group alone. This study indicates that the effect of attachment secure priming on the processing of emotional facial stimuli could be mediated by chronic attachment anxiety. In addition, it highlights the association between higher-order processes of the attachment system (secure attachment schema priming) and early-stage information processing system (attention), given the increased attention toward the effects of secure base schema on the processing of emotion- and attachment-related information among the insecure population. Thus, the following study has applications in providing directions for clinical treatment of mood disorders in attachment anxiety.

The processing of body expressions during emotional scenes: the modulation role of attachment styles

There is broad evidence indicating that contextual information influence the processing of emotional stimuli. However, attachment theory suggests that attachment styles contribute to the ways in which people perceive emotional events. To shed light on whether the processing of body expressions during different emotional scenes is modulated by attachment styles, attachment-related electrophysiological differences were measured using event-related potentials. For avoidantly attached group, our results suggested that larger N170 amplitudes were educed by neutral bodies than angry bodies, which was found only in neutral scene. Moreover, significant differences were found in P300 amplitudes in response to angry bodies compared with neutral ones only during angry scene. However, securely and anxiously attached individuals were associated with larger P300 amplitudes in response to angry bodies versus neutral ones in both emotional scenes. The current study highlights the characteristics of cognitive processing of attachment styles on body expressions during different emotional scenes, with the variation of N170 and P300 amplitude in different emotional scenes as the best example.

The vigilance-avoidance model of avoidant recognition: An ERP study under threat priming

Our study examined attachment-related electrophysiological differences in recognition using event-related potentials (ERPs) measured during a study-test paradigm after threat priming. We identified ERP correlates of recognition by comparing the ERPs of attachment-related positive and negative images between avoidant and secure attachment orientations. Our results revealed that the distribution of early old/new effects was broader in avoidant individuals than in secure individuals, and an early parietal old/new effect was observed in avoidant individuals, which reflected their implicit memory. The late old/new effect was found only in secure individuals when evoked by negative pictures, and was not observed in avoidant individuals. The results suggest that avoidant individuals adopt the "vigilance-avoidance" dual-process model to recognize both positive and negative attachment-related stimuli and carry out preferential familiarity matching at the automatic level and avoidant retrieval at the controlled-processing level.

Latent constructs model explaining the attachment-linked variation in autobiographical remembering

In the current study, we proposed a latent constructs model to characterise the qualitative aspects of autobiographical remembering and investigated the structural relations in the model that may vary across individuals. Primarily, we focused on the memories of romantic relationships and argued that attachment anxiety and avoidance would be reflected in the ways that individuals encode, rehearse, or remember autobiographical memories in close relationships. Participants reported two positive and two negative relationship-specific memories and rated the characteristics for each memory. As predicted, the basic memory model yielded appropriate fit, indicating that event characteristics (EC) predicted the frequency of rehearsal (RC) and phenomenology at retrieval (PC). When attachment variables were integrated, the model showed that rehearsal mediated the link between anxiety and PC, especially for negative memories. On the other hand, for avoidance EC was the key factor mediating the link between avoidance and RC, as well as PC. Findings were discussed with respect to autobiographical memory functions emphasising a systematically, integrated framework.

The relation between insecure attachment and posttraumatic stress: Early life versus adulthood traumas

The present study examined the relations between insecure attachment and posttraumatic stress disorder (PTSD) symptoms among community-dwelling older adults with exposure to a broad range of traumatic events. Attachment anxiety and attachment avoidance predicted more severe symptoms of PTSD and explained unique variance in symptom severity when compared to other individual difference measures associated with an elevated risk of PTSD, including NEO neuroticism and event centrality. A significant interaction between the developmental timing of the trauma and attachment anxiety revealed that the relation between PTSD symptoms and attachment anxiety was stronger for individuals with current PTSD symptoms associated with early life traumas compared to individuals with PTSD symptoms linked to adulthood traumas. Analyses examining factors that account for the relation between insecure attachment and PTSD symptoms indicated that individuals with greater attachment anxiety reported stronger physical reactions to memories of their trauma and more frequent voluntary and involuntary rehearsal of their trauma memories. These phenomenological properties of trauma memories were in turn associated with greater PTSD symptom severity. Among older adults with early life traumas, only the frequency of involuntary recall partially accounted for the relation between attachment anxiety and PTSD symptoms. Our differential findings concerning early life versus adulthood trauma suggest that factors underlying the relation between attachment anxiety and PTSD symptoms vary according to the developmental timing of the traumatic exposure. Overall our results are consistent with attachment theory and with theoretical models of PTSD according to which PTSD symptoms are promoted by phenomenological properties of trauma memories.

Neurocognitive considerations in the treatment of attachment and complex trauma in children

Accumulating evidence suggests that children suffering deprivation and maltreatment at critical times in their development often pay a cognitive toll. While children vary to the extent that neurocognitive domains are affected, those factors influence how children process, manage and understand traumatic and attachment experiences as well as how they respond to treatment. Current research on trauma and attachment favor some aspects of cognition over others. The literature discusses attention, memory, cognitive biases, internal working models, beliefs and attributions as ways that impact an individual's understanding of experience. Other categories such as working memory, processing speed, verbal, auditory or perceptual processing, metacognitive skills, and cognitive rigidity or flexibility rarely surface. This paper examines what is and is not known about the interface of cognition with attachment and complex trauma and how that knowledge can inform treatment. It explores existing research and offers a case vignette as an example of how that knowledge can be integrated into treatment strategies.

Attachment anxiety moderates the relationship between childhood maltreatment and attention bias for emotion in adults

Research indicates that some individuals who were maltreated in childhood demonstrate biases in social information processing. However, the mechanisms through which these biases develop remain unclear-one possible mechanism is via attachment-related processes. Childhood maltreatment increases risk for insecure attachment. The internal working models of self and others associated with insecure attachment may impact the processing of socially relevant information, particularly emotion conveyed in facial expressions. We investigated associations among child abuse, attachment anxiety and avoidance, and attention biases for emotion in an adult population. Specifically, we examined how self-reported attachment influences the relationship between childhood abuse and attention bias for emotion. A dot probe task consisting of happy, threatening, and neutral female facial stimuli was used to assess possible biases in attention for socially relevant stimuli. Our findings indicate that attachment anxiety moderated the relationship between maltreatment and attention bias for happy emotion; among individuals with a child abuse history, attachment anxiety significantly predicted an attention bias away from happy facial stimuli.

False memory for trauma-related Deese-Roediger-McDermott lists in adolescents and adults with histories of child sexual abuse

The purpose of the present research was to examine Deese-Roediger-McDermott false memory for trauma-related and nontrauma-related lists in adolescents and adults with and without documented histories of child sexual abuse (CSA). Individual differences in psychopathology and adult attachment were also explored. Participants were administered free recall and recognition tests after hearing CSA, negative, neutral, and positive Deese-Roediger-McDermott lists. In free recall, CSA and negative lists produced the most false memory. In sharp contrast, for recognition, CSA lists enjoyed the highest d' scores. CSA-group adolescents who evinced greater posttraumatic stress disorder (PTSD) symptoms had higher rates of false memory compared to (a) non-CSA group adolescents with higher PTSD symptom scores (free recall), and (b) CSA-group adolescents with lower PTSD symptom scores (recognition). Regression analyses revealed that individuals with higher PTSD scores and greater fearful-avoidant attachment tendencies showed less proficient memory monitoring for CSA lists. Implications for trauma and memory development and for translational research are discussed.

Attachment insecurities, maladaptive perfectionism, and eating disorder symptoms: a latent mediated and moderated structural equation modeling analysis across diagnostic groups

Although 96-100% of individuals with eating disorders (EDs) report insecure attachment, the specific mechanisms by which adult insecure attachment dimensions affect ED symptomatology remain to date largely unknown. This study examined maladaptive perfectionism as both a mediator and a moderator of the relationship between insecure attachment (anxiety and avoidance) and ED symptomatology in a clinical, treatment seeking, sample. Insecure anxious and avoidant attachment, maladaptive perfectionism, and ED symptomatology were assessed in 403 participants from three medium size specialized care centres for EDs in Italy. Structural equation modeling indicated that maladaptive perfectionism served as mediator between both insecure attachment patterns and ED symptomatology. It also interacted with insecure attachment to predict higher levels of ED symptoms - highlighting the importance of both insecure attachment patterns and maladaptive aspects of perfectionism as treatment targets. Multiple-group comparison analysis did not reveal differences across diagnostic groups (AN, BN, EDNOS) in mediating, main and interaction effects of perfectionism. These findings are consistent with recent discussions on the classification and treatment of EDs that have highlighted similarities between ED diagnostic groups and could be viewed through the lens of the Trans-theoretical Model of EDs. Implications for future research and intervention are discussed.

Motivation matters: differing effects of pre-goal and post-goal emotions on attention and memory

People often show enhanced memory for information that is central to emotional events and impaired memory for peripheral details. The intensity of arousal elicited by an emotional event is commonly held to be the mechanism underlying memory narrowing, with the implication that all sources of emotional arousal should have comparable effects. Discrete emotions differ in their effects on memory, however, with some emotions broadening rather than narrowing the range of information attended to and remembered. Thus, features of emotion other than arousal appear to play a critical role in memory narrowing. We review theory and research on emotional memory narrowing and argue that motivation matters. Recent evidence suggests that emotions experienced prior to goal attainment or loss lead to memory narrowing whereas emotions experienced after goal attainment or loss broaden the range of information encoded in memory. The motivational component of emotion is an important but understudied feature that can help to clarify the conditions under which emotions enhance and impair attention and memory.

Neuroscience of human social interactions and adult attachment style

Since its first description four decades ago, attachment theory (AT) has become one of the principal developmental psychological frameworks for describing the role of individual differences in the establishment and maintenance of social bonds between people. Yet, still little is known about the neurobiological underpinnings of attachment orientations and their well-established impact on a range of social and affective behaviors. In the present review, we summarize data from recent studies using cognitive and imaging approaches to characterize attachment styles and their effect on emotion and social cognition. We propose a functional neuroanatomical framework to integrate the key brain mechanisms involved in the perception and regulation of social emotional information, and their modulation by individual differences in terms of secure versus insecure (more specifically avoidant, anxious, or resolved versus unresolved) attachment traits. This framework describes how each individual's attachment style (built through interactions between personal relationship history and predispositions) may influence the encoding of approach versus aversion tendencies (safety versus threat) in social encounters, implicating the activation of a network of subcortical (amygdala, hippocampus, striatum) and cortical (insula, cingulate) limbic areas. These basic and automatic affective evaluation mechanisms are in turn modulated by more elaborate and voluntary cognitive control processes, subserving mental state attribution and emotion regulation capacities, implicating a distinct network in medial prefrontal cortex (mPFC), superior temporal sulcus (STS), and temporo-parietal junction (TPJ), among others. Recent neuroimaging data suggest that affective evaluation is decreased in avoidantly but increased in anxiously attached individuals. In turn, although data on cognitive control is still scarce, it points toward a possible enhancement of mental state representations associated with attachment insecurity and particularly anxiety. Emotion regulation strategies such as reappraisal or suppression of social emotions are also differentially modulated by attachment style. This research does not only help better understand the neural underpinnings of human social behavior, but also provides important insights on psychopathological conditions where attachment dysregulation is likely to play an important (causal) role.

Adolescent attachment insecurity and parasympathetic functioning predict future loss adjustment

Losing a close relationship is highly stressful and a robust predictor of major depression in adolescents. The current study examined relationships between attachment insecurity, parasympathetic nervous system activity, indexed by respiratory sinus arrhythmia (RSA), and adolescent adjustment to the loss of a close social partner. Adolescents with more attachment anxiety to their mother at age 14 were more likely to report poorer adjustment to a subsequent loss than adolescents with less attachment anxiety. Attachment avoidance interacted with stress-induced changes in RSA to predict loss adjustment. Among adolescents with higher RSA in response to the stressor, those with more attachment avoidance reported better loss adjustment, whereas among adolescents with lower RSA in response to the stressor, those with more attachment avoidance reported poorer loss adjustment. In sum, the combination of attachment insecurity and stress-induced changes in RSA predicted how well adolescents adjusted to a loss.

Models of intimacy of securely and avoidantly attached young adults: a narrative approach

This study compared models of intimacy implicit in the narratives of young adults (mean age, 25 years) with secure (n = 13) and avoidant (n = 13) attachment styles. Participants completed an open-ended interview in which they described past and present adult love relationships. Content analysis revealed that although secure and avoidant individuals expressed needs for both closeness and distance, the meaning they attached to these needs differed. Narratives of secure individuals were more likely to include themes of caring, idealization, and passion; in contrast, the narratives of avoidant individuals were more likely to contain themes of holding, self-validation, and calmness. Avoidant individuals implicitly endorse an "infant-mother" intimacy model, whereas secure individuals seem to hold a "two-adult" intimacy model.

Women with an avoidant attachment style show attenuated estradiol responses to emotionally intimate stimuli

The current study examined neuroendocrine processes associated with emotional intimacy in humans. Despite the importance of this aspect of close relationships, emotional intimacy has received much less attention in neuroendocrine research compared to other aspects of close relationships. In this study, participants viewed movie clips depicting an emotionally intimate parent-child interaction or other, non-intimate themes, and we assessed whether depictions of emotional intimacy increased levels of estradiol, a steroid hormone associated with attachment and caregiving processes. We also examined whether estradiol responses were moderated by individual differences in attachment avoidance, or people's discomfort with closeness and intimacy. Our findings revealed that, among single participants, estradiol levels increased in response to the emotionally intimate clip, but this effect was not observed among currently partnered participants. Moreover, the effects of emotional intimacy were moderated by gender and attachment avoidance, such that highly avoidant women showed smaller increases in estradiol after watching the emotionally intimate clip. Women's avoidance was unrelated to estradiol responses in the non-intimate control conditions, however, suggesting that the effects of avoidance were specific to intimate contexts. Taken together, the current findings contribute to our understanding of the biological bases of attachment and caregiving processes. They also highlight the potential role of estradiol in avoidant individuals' regulation of closeness and intimacy.

Emotional working memory capacity in posttraumatic stress disorder (PTSD)

Participants with a lifetime history of posttraumatic stress disorder (PTSD) and trauma-exposed controls with no PTSD history completed an emotional working memory capacity (eWMC) task. The task required them to remember lists of neutral words over short intervals while simultaneously processing sentences describing dysfunctional trauma-related thoughts (relative to neutral control sentences). The task was designed to operationalise an everyday cognitive challenge for those with mental health problems such as PTSD; namely, the ability to carry out simple, routine tasks with emotionally benign material, while at the same time tackling emotional laden intrusive thoughts and feelings. eWMC performance, indexed as the ability to remember the word lists in the context of trauma sentences, relative to neutral sentences, was poorer overall in the PTSD group compared with controls, suggestive of a particular difficulty employing working memory in emotion-related contexts in those with a history of PTSD. The possible implications for developing affective working memory training as an adjunctive treatment for PTSD are explored.

Sex differences in romantic attachment: a meta-analysis

This article presents the first meta-analysis of sex differences in the avoidance and anxiety dimensions of adult romantic attachment, based on 113 samples (N = 66,132) from 100 studies employing two-dimensional romantic attachment questionnaires (Experiences in Close Relationships, Experiences in Close Relationships-Revised, and Adult Attachment Questionnaire). Overall, males showed higher avoidance and lower anxiety than females, with substantial between-study heterogeneity. Sex differences were much larger in community samples (bivariate D = .28) than in college samples (D = .12); web-based studies showed the smallest sex differences (D = .07) in the opposite direction. Sex differences also varied across geographic regions (overall Ds = .10 to .34). Sex differences in anxiety peaked in young adulthood, whereas those in avoidance increased through the life course. The relevance of these findings for evolutionary models of romantic attachment is discussed, and possible factors leading to underestimation of sex differences are reviewed.

Autobiographical memory development from an attachment perspective: the special role of negative events

The authors propose a novel model of autobiographical memory development that features the fundamental role of attachment orientations and negative life events. In the model, it is proposed that early autobiographical memory derives in part from the need to express and remember negative experiences, a need that has adaptive value, and that attachment orientations create individual differences in children's recollections of negative experiences. Specifically, the role of attachment in the processing of negative information is discussed in regard to the mnemonic stages of encoding, storage, and retrieval. This model sheds light on several areas of contradictory data in the memory development literature, such as concerning earliest memories and children's and adults' memory/suggestibility for stressful events.

Endogenous estradiol levels are associated with attachment avoidance and implicit intimacy motivation

Estradiol has been linked with attachment and caregiving processes in humans and other mammals; however, relations between estradiol and personality constructs relevant to intimate relationships have not yet been explored. In the present sample of 100 adult participants (52 men, 48 women), we examined endogenous estradiol levels in relation to two personality constructs that predict comfort with and desire for close, intimate relationships-attachment style and implicit intimacy motivation. In both men and women, estradiol levels were predicted by an interaction between a dimension of attachment style-attachment avoidance-and implicit intimacy motivation. Specifically, the highest estradiol levels were observed among participants whose explicit traits support the expression of their implicit motives, that is, those characterized by both low avoidance and high intimacy motivation. Our findings provide novel evidence that endogenous estradiol levels are associated with relationship-relevant personality constructs in theoretically meaningful ways. These findings also highlight the importance of considering interactions between implicit and explicit personality constructs in the study of the biological bases of personality.

Adult attachment, personality traits, and borderline personality disorder features in young adults

Previous studies have demonstrated that insecure attachment patterns and a trait disposition toward negative affect and impulsivity are both associated with borderline personality disorder (BPD) features. According to attachment theory, insecure attachment patterns impart greater risk for the maladaptive personality traits underlying BPD. Hence, insecure attachment might be indirectly related to BPD through its association with these traits. The current cross-sectional study used structural equation modeling to compare two competing models of the relationship between adult attachment patterns, trait negative affect and impulsivity, and BPD features in a large nonclinical sample of young adults: (M1) attachment anxiety and avoidance are positively related to trait negative affect and impulsivity, which in turn, are directly associated with BPD features; and (M2) trait negative affect and impulsivity are positively related to attachment anxiety and avoidance, which in turn, are directly associated with BPD features. Consistent with attachment theory, M1 provided a better fit to the data than M2. However, only attachment anxiety, and not attachment avoidance, was significantly associated with negative affect and impulsivity. The results favored a model in which the relationship between adult attachment anxiety and BPD features is fully mediated by trait negative affect and impulsivity.

Avoiding interference: adult attachment and emotional processing biases

The present study investigated attachment-related differences in emotional processing biases. Consistent with the proposal that avoidant individuals limit attention to potentially distressing information, attachment avoidance was associated with reductions in emotional Stroop (ES) interference for attachment-related words (e.g., intimate, loss). These biases were strongest among individuals who were currently in a romantic relationship, suggesting that being in a close relationship may activate avoidant defensive strategies. In addition, avoidant attentional biases were attenuated under cognitive load, suggesting that inhibiting attention to attachment-related information requires cognitive effort. Finally, avoidance was unrelated to ES performance for emotional, nonattachment-related words, demonstrating the specificity of these attentional biases. The present findings suggest that avoidant individuals can inhibit attention to potentially threatening information, that this ability requires cognitive effort, and that relationship status may be an important moderator of avoidant defensive strategies. The implications of these strategies for emotional functioning and well-being are discussed.
