Though some evidence showed that negative mood has a differential effect on verbal and visuospatial WM, other findings did not report a similar effect. To explore this issue, we examined the negative mood’s impact on verbal and visuospatial WM executive tasks based on grammatical reasoning and visuospatial rotation. Participants with no anxiety or depression disorders performed the tasks before and after negative (n = 14) or neutral (n = 13) mood induction. Participants’ mood at the beginning and the end of the session was assessed by the Present Mood States List (LEAP) and word valence rating. The analyses showed changes in the emotional state of the negative group (ps < .03) but not of the neutral group (ps > .83) in the LEAP instrument. No significant differences between groups were observed in the WM tasks (ps > .3...

Participants memorised two face arrays with the same emotion but different identities and were required to judge whether the test face had the same identity as one of the previous faces. Concurrently during encoding and maintenance, a sequence of high-or-low pitched tones (high load) or white noise bursts (low load) was presented, and participants were required to count how many low-tones were heard. Experiment 1 and 2 used an emotional and neutral test face, respectively. The results revealed a significant WM impairment for sad and angry faces in the high load vs low load condition but not for happy faces. Happy faces were better recognised than other emotional faces in a high load. In Experiment 1, participants remembered better happy faces than other emotional faces. In contrast, Experiment 2 showed that performance was poorer for happy than sad faces but not for angry ...

Tal ação colabora para desenvolver novas formas de ensinar, de aplicar estratégias de ensino e gera dados para compreensão de tais questões, contemplando, assim, os três grandes objetivos da universidade: docência, pesquisa e extensão. O presente trabalho, de natureza descritiva, visa apresentar a produção de um projeto de extensão universitária como possibilidade de aproximação entre universidade e sociedade a partir do processo de criação de cursos de difusão científica de temas de um Programa de Pós-Graduação em Psicobiologia. O processo envolveu a escolha das áreas e conteúdos dos cursos, do público-alvo, ambiente virtual de aprendizagem e das formas de divulgação. Foram estruturados quatro cursos, sendo que um deles foi realizado e contou com a participação de 81 alunos. Concluímos que o processo de criação da proposta fomentou habili...
