Exploring Task Design and Heuristics Interaction Through a Knowledge‐Free Option Generation Task
Past research on option generation, the mental process of creating possible courses of action for goal‐directed behaviors, focused extensively on the outcomes of the process, specifically, the quantity and quality of options generated. Accordingly, various effects were introduced to describe and categorize observed trends in option properties, yet these studies utilize differing task designs. This paper focuses on the “quantity‐breeds‐quality”, “…
Stress exposure in at‐risk , depressed, and suicidal adolescents
Background Stress exposure contributes to the onset, maintenance, and recurrence of major depressive disorder (MDD) in adolescents. However, the precise stress facets (e.g. chronicity, domain) most strongly linked to outcomes at different stages along the depression severity continuum remain unclear. Across two studies, chronic and episodic stressors were comprehensively assessed among: (a) healthy youth with (High‐Risk [HR]) and without (Low‐Ris…
St Annual Scientific Meeting Biopsychosocial Health in Context March 20-23, 2024, Brighton, UK
The impact of perseverative cognition in the development and maintenance of psychiatric disorders has been mainly investigated in the context of individuals’ responses to aversive situations. Limited and contrasting evidence has emerged about the role of perseverative cognition in the positive valence systems domain. The present study combined laboratory-based assessment of reward responsiveness and electrophysiology to examine the effects of wor…
Longitudinal associations between five factor model and impulsive personality traits and PTSD symptoms
Neural sensitivity to peer feedback and depression symptoms in adolescents
BACKGROUND: Depression risk increases during adolescent development, and individual differences in neural sensitivity to peer feedback (rejection vs. acceptance) may be a key diathesis in understanding stress-related depression risk. METHODS: At baseline, adolescents (12-14 years old; N = 124) completed clinical interviews and self-report symptom measures, and the Chatroom Task while MRI data were acquired. The majority of participants provided u…
A mesocorticolimbic signature of pleasure in the human brain
Stress-induced alterations in HPA-axis reactivity and mesolimbic reward activation in individuals with emotional eating
Fast evidence accumulation in social anxiety disorder enhances decision making in a probabilistic reward task
Choices and response times in two-alternative decision-making tasks can be modeled by assuming that individuals steadily accrue evidence in favor of each alternative until a response boundary for one of them is crossed, at which point that alternative is chosen. Prior studies have reported that evidence accumulation during decision-making tasks takes longer in adults with psychopathology than in healthy controls, indicating that slow evidence acc…
Reward Learning, Neurocognition, Social Cognition, and Symptomatology in Psychosis
Reward learning was associated with symptoms of psychosis - in particular negative symptoms - across diagnoses, and was predictive of worse social cognition. Reward learning was not associated with neurocognitive performance, suggesting that, across patient groups, social cognition but not neurocognition may share common pathways with this aspect of reinforcement learning. Better understanding of how cognitive dysfunction and reward processing de…
Large-Scale Network Dysfunction in Major Depressive Disorder
Effects of early life stress on cognitive and affective function
Task feedback effects on conflict monitoring and executive control
Emerging evidence suggests that depression is associated with executive dysfunction, particularly after committing errors or receiving negative performance feedback. To test this hypothesis, 57 participants performed two executive tasks known to elicit errors (the Simon and Stroop Tasks) during positive or negative performance feedback. Participants with elevated depressive symptoms (Beck Depression Inventory scores >or= 13) were characterized by…
Anxiety selectively disrupts visuospatial working memory
On the basis of a review of the extant literature describing emotion-cognition interactions, the authors propose 4 methodological desiderata for studying how task-irrelevant affect modulates cognition and present data from an experiment satisfying them. Consistent with accounts of the hemispheric asymmetries characterizing withdrawal-related negative affect and visuospatial working memory (WM) in prefrontal and parietal cortices, threat-induced a…
The Worried Mind
To study the psychophysiological correlates of worrying, the authors recorded heart rate, respiratory sinus arrhythmia (RSA), skin conductance level, and alpha electroencephalographic asymmetry in healthy males during baseline, relaxation, worry induction, and anticipation of an impromptu speech task. Compared with baseline, relaxation, and anticipation, worrying was associated with greater heart rate and lower RSA. Worrying was further character…
