ABSTRACT

Maternal psychological factors, including anxiety, depression, and substance use, may negatively affect parenting. Previous works with mothers have often assessed each of these factors in isolation despite their frequent co-occurrence. Psychological factors have also been associated with neural processing of facial stimuli, specifically the amplitude (i.e., size) and latency (i.e., timing) of the face-specific N170 event-related potential. In the current study, 106 mothers completed measures assessing maternal psychological factors-anxiety, depression, and substance use. A latent profile analysis was used to identify profiles of psychological factors and assess profile associations with the N170 elicited by infant faces and with parental reflective functioning (PRF) as a measure related to caregiving. Two profiles (termed high and low psychological risk) were identified, with the higher risk profile associated with delayed N170 latency responses to infant faces. An exploratory analysis evidenced an indirect effect between the higher psychological risk profile and lower PRF through delayed N170 latency responses to infant faces. Taken together, maternal psychological risk across multiple indicators may together shape neural processing of infant faces, which may have downstream consequences for caregiving.

ABSTRACT

Reward-related activity in the dopaminergic midbrain is thought to guide animal behavior, in part by boosting the perceptual and attentional processing of reward-predictive environmental stimuli. In line with this incentive salience hypothesis, studies of human visual search have shown that simple synthetic stimuli, such as lines, shapes, or Gabor patches, capture attention to their location when they are characterized by reward-associated visual features, such as color. In the real world, however, we commonly search for members of a category of visually heterogeneous objects, such as people, cars, or trees, where category examples do not share low-level features. Is attention captured to examples of a reward-associated real-world object category? Here, we have human participants search for targets in photographs of city and landscapes that contain task-irrelevant examples of a reward-associated category. We use the temporal precision of EEG machine learning and ERPs to show that these distractors acquire incentive salience and draw attention, but do not capture it. Instead, we find evidence of rapid, stimulus-triggered attentional suppression, such that the neural encoding of these objects is degraded relative to neutral objects. Humans appear able to suppress the incentive salience of reward-associated objects when they know these objects will be irrelevant, supporting the rapid deployment of attention to other objects that might be more useful. Incentive salience is thought to underlie key behaviors in eating disorders and addiction, among other conditions, and the kind of suppression identified here likely plays a role in mediating the attentional biases that emerge in these circumstances.Significance Statement Like other animals, humans are prone to notice and interact with environmental objects that have proven rewarding in earlier experience. However, it is common that such objects have no immediate strategic use and are therefore distracting. Do these reward-associated real-world objects capture our attention, despite our strategic efforts otherwise? Or are we able to strategically control the impulse to notice them? Here we use machine learning classification of human electrical brain activity to show that we can establish strategic control over the salience of naturalistic reward-associated objects. These objects draw our attention, but do not necessarily capture it, and this kind of control may play an important role in mediating conditions like eating disorder and addiction.

ABSTRACT

Maternal attachment security is an important predictor of caregiving . However, little is known regarding the neurobiological mechanisms by which attachment influences processing of infant cues, a critical component of caregiving. We examined whether attachment security, measured by the Adult Attachment Interview, might relate to neural responses to infant cues using event-related potentials. Secure (n=35) and insecure (n=24) mothers viewed photographs of infant faces and heard recordings of infant vocalizations while electroencephalography was recorded. We examined initial processing of infant faces (N170) and cries (N100), and attentional allocation to infant faces and cries (P300). Secure mothers were significantly faster than insecure mothers to orient to infant cries (N100), structurally encode their own infant's face (N170), and attend to infant faces (P300). These differences may elucidate mechanisms underlying how attachment may shape neural processing of infant cues and highlight the use ofsocial neuroscientific approaches in examining clinically relevant aspects of attachment.

ABSTRACT

Objective: Research has demonstrated relative success with brief interventions that utilize social psychological theory to target the root cause of unwanted behaviours. Given the intersections among anxious attachment, depression, and emotion dysregulation, the current research utilises an interpersonal conflict cognitive reappraisal intervention to evaluate improvements in depressive symptoms. We also evaluated mediation via improvements in emotion regulation and moderation by attachment anxiety. Design: Undergraduates (N = 260) completed a baseline assessment and were randomised to one of four writing conditions: An interpersonal conflict from (a) their own perspective; (b) the other party's perspective; or (c) a neutral, third-party perspective (primary experimental condition) or about their day (control condition). They also completed a follow-up survey online two weeks later. Main outcome measures included limited access to emotion regulation strategies and depressive symptoms. Results: Consistent with hypotheses, compared to control, participants who adopted the perspective of neutral third party reported improvements in access to emotion regulation strategies. There was also a significant indirect effect on depressive symptoms through changes in strategies. Finally, improving strategies led to a reduction in depressive symptoms, especially for those higher in attachment anxiety. Conclusion: We present promising emerging results for a single-session, conflict-focused, brief cognitive reappraisal intervention on changes in emotion regulation and depressive symptoms.

ABSTRACT

Research has shown links between interpersonal conflict and problematic drinking behaviors as a way to cope. The present research examined the effects of a brief interpersonal conflict cognitive reappraisal intervention on short-term reductions in alcohol-related problems in a sample of college student drinkers. Undergraduates who were regular drinkers (N = 190) participated in a randomized control online study, completing self-reported measures of alcohol consumption and alcohol-related problems at baseline and 2 weeks later. After completing the baseline survey, participants completed a brief writing intervention during which they were asked to reflect on a recent interpersonal conflict and write about it from 1 of 3 possible perspectives, 2 of which were targeting cognitive reappraisal (i.e., a neutral, third-party perspective and the other party's perspective), their own perspective, or to reflect on their activities that day (control). Results from negative binomial regression models supported both reappraisal conditions: Compared with control, those who thought about the conflict from a neutral third-party perspective and those who thought about the conflict from the other party's perspective reported significantly fewer drinking problems at follow-up. Results from this study suggest preliminary efficacy of a single-session writing intervention aimed at reappraising interpersonal conflict.
