Previous research using a thought suppression paradigm found that repressors are more skilled in suppressing anxious autobiographical thoughts than low anxious, high anxious, and defensive high anxious people. Another line of research showed that individual differences in working memory capacity are related to the ability to intentionally suppress intrusive thoughts. This study aimed at combining these findings and sought to investigate whether repressors' superior ability to suppress intrusive thoughts is related to a larger working memory capacity. Results indicate that in a thought suppression paradigm, repressors report fewer intrusive thoughts for their most anxious experiences than participants in the 3 other subgroups. Furthermore, the superior ability of repressors to avoid intrusive thoughts can be explained largely by their higher working memory capacity.

Mapping patterns of thought onto brain activity during movie-watching.
Elife

Department of Psychology, Queens University, Kingston, Canada.
Movie-watching is a central aspect of our lives and an important paradigm for understanding the brain mechanisms behind cognition as it occurs in daily life. Contemporary views of ongoing thought argue that the ability to make sense of events in the 'here and now' depend on the neural processing of incoming sensory information by auditory and visual cortex, which are kept in check by systems in association cortex. However, we currently lack an understanding of how patterns of ongoing thoughts map onto the different brain systems when we watch a film, partly because methods of sampling experience disrupt the dynamics of brain activity and the experience of movie-watching.

Department of Psychology and Neuroscience, Dalhousie University.
Objective: We examined whether hangover-related rumination-repeatedly dwelling on negative aspects of yesterday's drinking while hungover the following morning-predicts changes in three dimensions of heavy episodic drinking (HED) over time.
Method: = 334 emerging adults (aged 19-29) from three Eastern Canadian universities who had recently experienced a hangover completed online self-report questionnaires at baseline (Wave 1) and 30 days later (Wave 2; 71.6% retention).
Experience of post-traumatic growth among parents of children with biliary atresia undergoing living-related liver transplantation: a descriptive phenomenological study.

To explore the experience of post-traumatic growth among parents of children with biliary atresia undergoing living-related liver transplantation.: Participants were recruited within 2 weeks of their child's transplant surgery using purposive sampling. Transcripts were analyzed using Colaizzi's descriptive analysis framework, with collaborative analysis conducted using NVivo 12 software and a post-traumatic growth model.

In humans, grief is characterized by intense sadness, intrusive thoughts of the deceased, and intense longing for reunion with the deceased. Human fMRI studies show hyperactivity in emotional pain and motivational centers of the brain when an individual is reminded of a deceased attachment figure, but the molecular underpinnings of these changes in activity are unknown. Prairie voles (Microtus ochrogaster), which establish lifelong social bonds between breeding pairs, also display distress and motivational shifts during periods of prolonged social loss, providing a model to investigate these behavioral and molecular changes at a mechanistic level.

Bathymetry critically influences the intrusion of warm Circumpolar Deep Water onto the continental shelf and under ice shelf cavities in Antarctica, thereby forcing ice melting, grounding line retreat, and sea level rise. We present a novel and comprehensive bathymetry of Antarctica that includes all ice shelf cavities and previously unmeasured continental shelf areas. The new bathymetry is based on a 3D inversion of a circumpolar compilation of gravity anomalies constrained by measurements from the International Bathymetric Chart of the Southern Ocean, BedMachine Antarctica, and discrete seafloor measurements from seismic and ocean robotic probes.
