Targeted memory reactivation (TMR) during post-learning sleep is known to enhance motor memory consolidation but the underlying neurophysiological processes remain unclear. Here, we confirm the beneficial effect of auditory TMR on motor performance. At the neural level, TMR enhanced slow wave (SW) characteristics. Additionally, greater TMR-related phase-amplitude coupling between slow (0.5-2 Hz) and sigma (12-16 Hz) oscillations after the SW peak was related to higher TMR effect on performance. Importantly, sounds that were not associated to learning strengthened SW-sigma coupling at the SW trough. Moreover, the increase in sigma power nested in the trough of the potential evoked by the unassociated sounds was related to the TMR benefit. Altogether, our data suggest that, depending on their precise temporal coordination during post learning sleep, slow and sigma oscillations play a crucial role in either memory reinstatement or protection against irrelevant information; two processes that critically contribute to motor memory consolidation.

Despite numerous studies demonstrating the influence of cognitive distortions on gambling problem severity, empirical data regarding the role of psychological vulnerability on the latter is limited. Hence, this study assesses the mediating effect of cognitive distortions between psychological vulnerability (personality and mood), and gambling problem severity. It also verifies whether the relationships between these variables differs according to the preferred gambling activity. The sample is composed of 272 male gamblers [191 poker players; 81 video lottery terminal (VLT) players] aged between 18 and 82 years (M = 35.2). Bootstrap analysis results revealed that cognitive distortions mediate the effect of narcissism on gambling problem severity for both groups. The level of depression for VLT players significantly predicted gambling problem severity, both directly and indirectly via the mediating effect of cognitive distortions. Mediation analyses also indicated that narcissism had an indirect impact on problem gambling through cognitive distortions for both groups. These findings suggest that certain vulnerabilities related to personality and mood may influence cognitive distortion intensity and gambling problem severity. In addition, psychological vulnerabilities could differ based on preferred gambling activity. These results may be useful for prevention policies, identifying high risk gamblers and planning psychological interventions.

Ce qu'un individu pense de son apparence est intimement lié à ses relations interpersonnelles et à ce qu'il croit que les autres pensent de son apparence, notamment dans le contexte des relations amoureuses. La sexualité est une dimension du fonctionnement conjugal particulièrement sensible aux difficultés reliées à l'image corporelle, en raison des cognitions et des émotions liées à l'apparence qui sont en jeu lors du dévoilement de soi et du partage d'intimité associés à la sexualité. Cette étude vérifie, parmi 103 couples hétérosexuels, des modèles d'analyses acheminatoires reliant l'image corporelle, la sexualité et la satisfaction conjugale (femmes et hommes séparément) ainsi que des modèles d'interdépendance acteurpartenaire (couples). Chez les femmes, l'insatisfaction corporelle est associée négativement à la satisfaction sexuelle et conjugale par l'affirmation sexuelle et les distractions cognitives. Chez les hommes, la perception de ce que leur conjointe pense de leur corps est associée négativement à la satisfaction sexuelle et conjugale, notamment par les distractions cognitives. Dans les modèles d'interdépendance acteur-partenaire, l'insatisfaction corporelle des femmes est liée négativement à la satisfaction sexuelle et conjugale de leur conjoint. Le niveau d'affirmation sexuelle des hommes et des femmes est lié positivement à la satisfaction sexuelle et conjugale de leur conjoint respectif.
