An attachment theoretical perspective for the neural representation of close others.

Recent investigations in neuroscience elucidate the neural basis of close other cognitive representations, which serve functions central to our health and happiness. Yet, there are persistent barriers to this research, including disparate research methods and the absence of a common theoretical background. The present review connects neuroimaging and attachment theory within a novel social, cognitive and affective framework. We apply attachment theory to understand why we would expect cognitive representations of close others to be different from other social neural representations. Developing reliable markers of attachment is a critical step in mapping close other neural representations. We then examine existing neuroimaging literature on close other representations, highlighting the recruitment of neural systems supporting reward, motivation and distress alleviation, in addition to the mirror neuron system, default network and salience network. We then review the methodologies of past studies, revealing a diverse array of self-report measures assessing `closeness' and social cognitive tasks that, taken together, preclude meaningful synthesis of findings. Lastly, we discuss specific behavioral measures of attachment and closeness with recommendations for the field. This attachment framework integrates brain and behavioral sciences and unites theoretical principles with empirical methods to further our understanding of how the brain represents close others.

Neural signatures of chronic accessibility in parent - adult child attachment bonds.

Some of the closest reciprocal relationships are between parents and their children. As part of the attachment characterizing many parent-child bonds, individuals form mental representations that are chronically accessible and calibrate expectations for future relationships. We predict that there exist unique neural signatures of this chronic accessibility. Young (N = 29, 16 females) and older adults (N = 27, 12 females) made trait judgments for parent or child, respectively, during fMRI scanning. Multivariate analysis identified whole-brain patterns of activation that covaried with the magnitude of parent-child attachment when thinking about that individual. Higher levels of parent and child attachment were associated with lower neural recruitment in anterior cingulate cortex, amygdala, posterior cingulate cortex, medial temporal lobe, and occipital face area. Results provide novel evidence for neural signatures of chronic accessibility, as bringing to mind one's attached parent or child requires less engagement of brain regions involved in distress relief, memory, and facial processing.

I Have, Therefore I Love: Status Quo Preference in Mate Choice.

Decades of research indicate that individuals adhere to existing states ("status quo bias") and value them more ("endowment effect"). The present work is the first to investigate status quo preference within the context of trade-offs in mate choice. Across seven studies (total N = 1,567), participants indicated whether they would prefer remaining with a current partner possessing a particular set of traits (e.g., high trustworthiness, low attractiveness) or switching to an alternative partner possessing opposite traits. Preference for a given trait was highest when the individual representing the status quo (one's romantic partner or an interaction partner) possessed that trait. Concerns about hurting the partner, ambiguity avoidance, and biased construal of the partner and the alternative predicted status quo preference and disapproval of the current partner by network members eliminated this effect. These findings indicate that when it comes to matters of the heart, we tend to love what we currently have.

Dissociable patterns of brain activity for mentalizing about known others: a role for attachment.

The human brain tracks dynamic changes within the social environment, forming and updating representations of individuals in our social milieu. This mechanism of social navigation builds an increasingly complex map of persons with whom we are familiar and form attachments to guide adaptive social behaviors. We examined the neural representation of known others along a continuum of attachment using fMRI. Heterosexual adults (N = 29, 16 females), in romantic relationships for more than 2 years, made trait judgments for a romantic partner, parent, close friend, familiar acquaintance and self-during scanning. Multivariate analysis, partial least squares, was used to identify whole-brain patterns of brain activation associated with trait judgments of known others across a continuum of attachment. Across conditions, trait judgments engaged the default network and lateral prefrontal cortex. Judgments about oneself and a partner were associated with a common activation pattern encompassing anterior and middle cingulate, posterior superior temporal sulcus, as well as anterior insula. Parent and close friend judgments engaged medial and anterior temporal lobe regions. These results provide novel evidence that mentalizing about known familiar others results in differential brain activity. We provide initial evidence that the representation of adult attachment is a distinguishing feature of these differences.

Mental representations of attachment figures facilitate recovery following upsetting autobiographical memory recall.

A growing literature shows that even the symbolic presence of an attachment figure facilitates the regulation of negative affect triggered by external stressors. Yet, in daily life, pernicious stressors are often internally generated--recalling an upsetting experience reliably increases negative affect, rumination, and susceptibility to physical and psychological health problems. The present research provides the first systematic examination of whether activating the mental representation of an attachment figure enhances the regulation of affect triggered by thinking about upsetting memories. Using 2 different techniques for priming attachment figure representations and 2 types of negative affect measures (explicit and implicit), activating the mental representation of an attachment figure (vs. an acquaintance or stranger) after recalling an upsetting memory enhanced recovery--eliminating the negative effects of the memory recall (Studies 1-3). In contrast, activating the mental representation of an attachment figure before recalling an upsetting memory had no such effect (Studies 1 and 2). Furthermore, activating the mental representation of an attachment figure after thinking about upsetting memories reduced negative thinking in a stream of consciousness task, and the magnitude of the attachment-induced affective recovery effects as assessed with explicit affect measures predicted mental and physical health in daily life (Study 3). Finally, a meta-analysis of the 3 studies (Study 4) showed that the regulatory benefits conferred by the mental representation of an attachment figure were weaker for individuals high on attachment avoidance. The implications of these findings for attachment, emotion regulation, and mental and physical health are discussed.

Coregulation, dysregulation, self-regulation: an integrative analysis and empirical agenda for understanding adult attachment, separation, loss, and recovery.

An integrative framework is proposed for understanding how multiple biological and psychological systems are regulated in the context of adult attachment relationships, dysregulated by separation and loss experiences, and, potentially, re-regulated through individual recovery efforts. Evidence is reviewed for a coregulatory model of normative attachment, defined as a pattern of interwoven physiology between romantic partners that results from the conditioning of biological reward systems and the emergence of felt security within adult pair bonds. The loss of coregulation can portend a state of biobehavioral dysregulation, ranging from diffuse psychophysiological arousal and disorganization to a full-blown (and highly organized) stress response. The major task for successful recovery is adopting a self-regulatory strategy that attenuates the dysregulating effects of the attachment disruption. Research evidence is reviewed across multiple levels of analysis, and the article concludes with a series of testable research questions on the interconnected nature of attachment, loss, and recovery processes.

Recognizing and treating uncommon behavioral and emotional disorders in children and adolescents who have been severely maltreated: reactive attachment disorder.

This article explores reactive attachment disorder, a disorder that has been linked to severe and chronic maltreatment. The fundamental concepts of attachment theory are reviewed briefly, and the two types of behaviors associated with reactive attachment disorder in children and adolescents are discussed. Treatment strategies are explored, including the controversial holding or rebirthing strategies.

Adoption as a natural experiment.

Adoption provides a unique opportunity for the study of child development. Because adopted children are raised in families in which they have no genetic relationship with their parents, and possibly none with their siblings, they provide a rare opportunity to study the relative importance of genetic, shared environmental, and nonshared environmental influences on the development of child characteristics and behaviors. Because children are adopted from a variety of circumstances and at a wide range of ages, studies of adopted children and their families provide researchers the opportunity to examine the short- and long-term influences of a wide range of environments on children's development. Because children are adopted into homes with a range of characteristics (e.g., multiracial homes), adoption provides the opportunity to study the range of influences of these homes on child development. Adoption research that focuses on each of these areas is reviewed in this article. We present conclusions about the value of adoption in psychological research and some reasons why many psychologists ignore the opportunities presented by studying adoptive families, as well as potential useful directions for future research with adopted children and their families.
