Relations Between Emotion and Working Memory: Evidence From Behavioural and Psychophysiological Studies

Abstract

Resumo. Baddeley (2007) propôs o Detector Hedônico para explicar a relação entre as emoções e memória operacional (MO). Esta revisão teve como objetivo sistematizar evidências da influência das emoções no desempenho em tarefas de MO a partir de artigos atuais e sua associação com o sistema Hedônico. Para isso, foi realizada uma pesquisa em variadas bases de dados que gerou 103 artigos em um período restrito (2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017). Foram selecionados dez artigos combinando testes comportamentais com medidas psicofisiológicas e dez artigos utilizando tarefas estritamente comportamentais. Em todas as abordagens foi observado que o tipo de demanda cognitiva subjacente à tarefa foi crucial para entender como o desempenho da MO é influenciado pelas emoções. Além disso, foi possível detectar uma tendência para explicação dos resultados com base no processamento executivo relacionado a um modelo neural da MO, visto que apenas um artigo comportamental explicou os resultados com base no sistema de detecção Hedônica.Palavras-chave: Emoção; memória operacional; revisão sistemática. (2007) proposed the Hedonic Detection to explain the connection between emotion and working memory (WM). This review aimed to systematize evidence of the influence of emotion on performance of WM tasks and its association with the Hedonic system on current studies. We carried out a database research that generated 103 papers in a restricted period (2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017). Ten papers combining behavioural tests with psychophysiological measures and ten papers using strictly behavioural tasks were selected. In all approaches were observed that the type of cognitive request underlying the task is crucial to understand how WM performance is influenced by emotion. Besides, was possible to detect a trend in the literature to focus on executive process related to a neural model for WM, since just only one behavioural paper explained the results based on Hedonic Detector system.

En la presente revisión se tuvo como objetivo sistematizar a partir de artículos actuales la influencia de las emociones en la performance de tareas de MO a partir de artículos actuales y su asociación con el sistema Hedónico.

Se seleccionaron 10 artículos conductuales combinados con medidas psicofisiológicas y otros 10 utilizaron solo medidas conductuales. En ambos abordajes se observó que el tipo de demanda cognitiva presente en la tarea es crucial para comprender cómo la ejecución en la tarea es influenciada por la emoción. Además, fue posible detectar una tendencia en la literatura a centrarse en el proceso ejecutivo relacionado con un modelo neural de MO; ya que solo un estudio conductual explicó sus resultad...

Neutral and negative mood induction in executive tasks of working memory

“…In contrast with Gray's (2001) findings, we found no support for the hypothesis that negative mood improves performance on visuospatial WM tasks. Compared with Gray's study, an explanation for the lack of the negative mood effect in this task might be related to task differences between studies (Ribeiro et al, 2018). For instance, our study failed to find a negative mood effect on a visuospatial WM executive function task based on the Shah and Miyake (1996) complex span test.…”

Scrutinizing Domains of Executive Function in Binge Eating Disorder: A Systematic Review and Meta-Analysis

“…In their review, Redick and Lindsey (66) pointed out that Span and N-back tasks measure different cognitive processes. Therefore, different tasks can be used to evaluate different working memory components, and combination of results of these tasks may provide biased results and inappropriate interpretation (67). In our meta-analysis of working memory, we were careful not to combine these two tests.…”

Emotional Induction Through Music: Measuring Cardiac and Electrodermal Responses of Emotional States and Their Persistence

“…In this sense, future studies should also address whether the musical preferences, personality, different ages would impact the persistence of emotions evoked by music, and how explicit valence–arousal reports might induce changes by themselves. Finally, the persistence of those emotions could also be assessed during diverse cognitive tasks, for instance with high and low cognitive demands, since it also seems to influence the persistence of evoked emotions ( Ribeiro et al, 2018 ).…”
