“…First, the sample was modest in size and In spite of these limitations, data highlight an activation pattern within frontoparietal and occipital regions during encoding that underlie interference control during a WMC task. The modified Rspan task appears to provide a tool for probing neural circuitry of WMC that differentiates the regions involved in interference control from set size, which may be relevant in future studies assessing populations (e.g., posttraumatic stress disorder; Bomyea, Amir, & Lang, 2012) or affective states (e.g., emotional arousal; Osaka, Yaoi, Minamoto, & Osaka, 2013) marked by deficits in this ability. In addition, empirical interest in training of cognitive functions dependent on interference control and working memory capacity in healthy and clinical samples has recently grown (Bomyea et al, 2015), with evidence that training-related changes may occur in both structural and functional neural activity (Engvig et al, 2010).…”

The extent to which one can use cognitive resources to keep information in working memory is known to rely on (1) active maintenance of target representations and (2) downregulation of interference from irrelevant representations. Neurobiologically, the global capacity of working memory is thought to depend on the prefrontal and parietal cortices; however, the neural mechanisms involved in controlling interference specifically in working memory capacity tasks remain understudied. In this study, 22 healthy participants completed a modified complex working memory capacity task (Reading Span) with trials of varying levels of interference control demands while undergoing functional MRI. Neural activity associated with interference control demands was examined separately during encoding and recall phases of the task. Results suggested a widespread network of regions in the prefrontal, parietal, and occipital cortices, and the cingulate and cerebellum associated with encoding, and parietal and occipital regions associated with recall. Results align with prior findings emphasizing the importance of frontoparietal circuits for working memory performance, including the role of the inferior frontal gyrus, cingulate, occipital cortex, and cerebellum in regulation of interference demands.

“…Ainda relacionado aos estudos que investigaram o desempenho verbal da MO, Osaka et al (2013) demonstraram piores resultados para o desempenho verbal da MO (Reading Span) com estímulos negativos em comparação com estímulos neutros. Além disso, Fairfield et al (2014) observaram que a precisão com palavras positivas e negativas diminuiu conforme as listas se estenderam, embora a extensão da lista não tenha tido impacto na recordação de palavras neutras.…”

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.

Se seleccionaron 10 artículos conductuales combinados con medidas psicofisiológicas y otros 10 utilizaron solo medidas conductuales.

“…It has been reported that both positive and negative affective picture stimuli improve working memory performance (Levens & Phelps, 2008;Lindström & Bohlin, 2011). Other studies have found that while positive stimuli are beneficial for working memory performance, negative stimuli impair it (Osaka, Yaoi, Minamoto, & Osaka, 2013;Perlstein, Elbert, & Stenger, 2002). A reason for the diverging results might be that when stimuli are perceived as threatening, the attentional resources are directed towards the threat, disrupting working memory performance (Pessoa, 2009).…”

The emotional dysregulation and impaired working memory found after sleep loss can have severe implications for our daily functioning. Considering the intertwined relationship between emotion and cognition in stimuli processing, there could be further implications of sleep deprivation in high-complex emotional situations.Although studied separately, this interaction between emotion and cognitive processes has been neglected in sleep research. The aim of the present study was to investigate the effect of 1 night of sleep deprivation on emotional working memory.Sixty-one healthy participants (mean age: 23.4 years) were either sleep deprived for 1 night (n = 30) or had a normal night's sleep (n = 31). They performed an N-back task with two levels of working memory load (1-back and 3-back) using positive, neutral and negative picture scenes. Sleep deprivation, compared with full night sleep, impaired emotional working memory accuracy, but not reaction times. The sleep-deprived participants, but not the controls, responded faster to positive than to negative and neutral pictures. The effect of sleep deprivation was similar for both high and low working memory loads. The results showed that although detrimental in terms of accuracy, sleep deprivation did not impair working memory speed. In fact, our findings indicate that positive stimuli may facilitate working memory processing speed after sleep deprivation.
