Abstract Attachment security describes a sense of safety and security felt by individuals and promotes mental health. The mechanism by which attachment security buffers against psychological threat remains unclear, however. Here, we explored how attachment security attenuates the response to threatening information using a signal detection theory (SDT) and event-related potentials (ERPs) approach. Participants were assigned to an attachment security priming condition or a control condition. After a priming procedure, behavioral data and electroencephalography (EEG) signals were recorded while participants categorized threatening and neutral pictures. Our behavioral results revealed that attachment security biased participant responses to categorizing the two types of pictures; participants in the control condition exhibited a tendency to categorize stimuli as threatening, whereas those in the attachment security condition tended to categorize stimuli as neutral. Meanwhile, attachment security priming modulated early attention processes, reflected by an increased P200. The findings reported here suggest that attachment security buffers against external threats by modulating individual response preferences, the effects of which manifest in the early stages of attentional processing.

ERP experiments generate massive datasets, often containing thousands of values for each participant, even after averaging. The richness of these datasets can be very useful in testing sophisticated hypotheses, but this richness also creates many opportunities to obtain effects that are statistically significant but do not reflect true differences among groups or conditions (bogus effects). The purpose of this paper is to demonstrate how common and seemingly innocuous methods for quantifying and...

Abstract This study examined the potential mediating roles of the cognitive risk factors of rumination and overgeneral memory in explaining the relationship between insecure attachments (avoidant and anxious) and depression. One hundred African American outpatient psychiatric patients completed the Experiences in Close Relationships Scale, the Ruminative Response Scale, the Diagnostic Inventory for Depression, and the Autobiographical Memory Test. Results supported a mediating role for ruminatio...

A predominant expectation that social relationships with others are safe (a secure attachment style), has been linked with reduced threat-related amygdala activation. Experimental priming of mental representations of attachment security can modulate neural responding, but the effects of attachment-security priming on threat-related amygdala activation remains untested. Using functional magnetic resonance imaging, the present study examined the effects of trait and primed attachment security on a...

Mothers are important to all humans. Research has established that maternal information affects individuals' cognition, emotion, and behavior. We measured event-related potentials (ERPs) to examine attentional and evaluative processing of maternal stimuli while participants completed a Go/No-go Association Task that paired mother or others words with good or bad evaluative words. Behavioral data showed that participants responded faster to mother words paired with good than the mother words pair...

Event-related potential (ERP) approaches to social cognitive and affective neuroscience (SCAN) are not as widely used as other neuroimaging techniques, yet they offer several unique advantages. In particular, the high temporal resolution of ERP measures of neural activity make them ideally suited for studying the dynamic interplay of rapidly unfolding cognitive and affective processes. In this article, we highlight the utility of ERP methods for scientists investigating questions of SCAN. We beg...

Abstract We propose an ethical intervention leading to improved ethical decision-making. Moral disengagement has long been related to unethical decision-making. We test an ethical intervention in which this relationship is broken. Our ethical intervention consisted of priming individuals to be securely-attached, in which they recalled a past instance of relational support and acceptance. We predicted and found an interaction between attachment state and moral disengagement, in which individuals ...

Abstract People's preference to help victims about whom they have some information is known as the identifiable victim effect. Results of three studies, in which dispositional attachment styles were measured (study 1) and activated in a between-subjects priming manipulation (studies 2 and 3), suggest that the intensity of this phenomenon is related to the potential helper's adult attachment style. Specifically, we found that secure people provide similar levels of help to identified and unidenti...

Abstract Attachment-related electrophysiological differences in emotional processing biases were examined using Event-Related Potentials (ERPs). We identified ERP correlates of emotional processing by comparing ERPs elicited in trials with angry and neutral faces. These emotional expression effects were then compared across groups with secure, anxious and avoidant attachment orientations. Results revealed significant interactions between attachment orientation and facial expression in mean ampli...

The current study examined the causal relationship between secure and anxious attachment orientations and pain sensitivity in a pain-free sample. In a double blind repeated measures study, a cold pressor task was used to induce acute pain in 95 participants before and after priming them with a secure or anxious attachment orientation or a neutral prime. Measures of pain threshold, tolerance, catastrophizing and intensity were taken. Compared to the neutral prime, secure and anxious primes result...
