Facing temptation: The neural correlates of gambling availability during sports picture exposure

Nowadays, sports betting has become increasingly available and easy to engage in. Here we examined the neural responses to stimuli that represent sporting events available for betting as compared to sporting events without a gambling opportunity. We used a cue exposure task in which football (soccer) fans (N = 42) viewed cues depicting scheduled football games that would occur shortly after the scanning session. In the “betting” condition, participants were instructed to choose, at the end of each block, the game (and the team) they wanted to bet on. In the “watching” condition, participants chose the game they would prefer to watch. After the scanning session, participants completed posttask rating questionnaires assessing, for each cue, their level of confidence about the team they believed would win and how much they would enjoy watching the game. We found that stimuli representing sport events available for betting elicited higher fronto-striatal activation, as well as higher insular cortex activity and functional connectivity, than sport events without a gambling opportunity. Moreover, games rated with more confidence towards the winning team resulted in greater brain activations within regions involved in affective decision-making (ventromedial prefrontal cortex), cognitive inhibitory control (medial and superior frontal gyri) and reward processing (ventral and dorsal striatum). Altogether, these novel findings offer a sensible simulation of how the high availability of sports betting in today’s environment impacts on the reward and cognitive control systems. Future studies are needed to extend the present findings to a sample of football fans that includes a samilar proportion of female and male participants.     

Field perspective deficit for positive memories characterizes autobiographical memory in euthymic depressed patients

Research on autobiographical memory (AM) and the ability to retrieve specific autobiographical events in euthymic depressed patients yielded divergent results. The main goal of the present study was to further explore episodic specificity of AM among fully remitted depressed patients. Twenty euthymic depressed patients and 20 matched healthy controls were given a semi-structured interview, which assesses episodic specificity of positive and negative autobiographical memories regarding event and details' specificity, autonoetic consciousness (remember/know procedure) and visual perspective (field/observer procedure). Results showed an impairment of episodic specificity of AM in euthymic depressed patients. This impairment was explained by a field perspective deficit for positive memories only. These results suggest that euthymic patients continue to exhibit discrepancy between their current self and their self for positive past behaviors, which maintains an unfavorable view of their current self. Specific cognitive interventions may improve the self-relevance of their positive memories.     

Parentification of Adult Siblings of Individuals with Autism Spectrum Disorder

Many typically-developing (TD) siblings provide care for their siblings with autism spectrum disorder (ASD), both as children and as adults. Research on parentification (i.e., when children assume responsibilities typically reserved for adults) has been mixed, with some studies supporting positive outcomes for TD siblings and others indicating negative outcomes. Some of these discrepancies may be due to inconsistencies in differentiating types of parentification. The current study examined how different types of parentification during childhood (retrospectively-reported) related to distress outcomes and attitudes about sibling relationships among 41 TD adult siblings of individuals with ASD. Results indicated that parent-focused parentification was positively related with anxiety and stress among TD siblings. Sibling-focused parentification was positively related to stress but was also related to more positive sibling relationship attitudes. Accounting for demographic variables and the other form of parentification, parent-focused parentification was a unique predictor of distress, whereas sibling-focused parentification was a unique predictor of positive sibling relationship attitudes. Although parentification is often viewed negatively, sibling-focused parentification and perceived benefits of parentification may predict positive outcomes. Results suggest that parentification may prove important in understanding the complex nature of sibling relationships. Specifically, strengthening the sibling bond and reducing parent-focused parentification during childhood may curtail sibling relationship problems and general distress in TD siblings later in life.
