Visual working memory resource allocation mechanism in consolidation and maintenance phase

2018

Visual working memory (VWM) is a system for actively maintaining visual information to meet the needs of an ongoing task. It allows individuals to store visual input information from a complex outside environment and provides storage space as an information buffer platform to help integrate information into a continuous visual experience. This research examined the consolidation and maintenance phase of the VWM resource allocation mechanism. Four aspects of this issue were investigated. First, resource allocation in VWM consolidation was investigated for different materials, and it was determined whether VWM resources were allocated in a serial manner for orientation materials but in a limi…

The mechanism of retro-cue effect in visual working memory : Cognitive phase separation

2020

Retro-cue effect (RCE) refers to the phenomenon that individuals can use retro-cues to improve their visual working memory (VWM) performance of target items after memory stimuli disappear. To explain the mechanism of RCE in VWM, five different hypotheses have been proposed by previous studies: the hypothesis of enhancing target representations, the hypothesis of forgetting non-target representations, the hypothesis of preventing memory degradation, the hypothesis of preventing interference from probe array and the hypothesis of cognitive phase separation. Although RCE has been repeatedly observed in previous studies, the mechanism of RCE remains unclear. In this study, we conducted three ex…

视觉工作记忆中回溯线索效应的影响因素 [The Influencing Factors of Retro-Cue Effect in Visual Working Memory]

2022

The visual working memory is a temporary storage system, which encodes, maintains and retrieves visual information. The researchers have found that adding retro-cues to the maintenance phase of memory leads to changes in participants’ memory performance, which is the retro-cue effect. The magnitude of the retro-cue effect is not set in stone, but changes with the changes of its influencing factors. However, there is no study to summarize the influencing factors of the retro-clue effect. This paper looked into the articles related to the study of the retro-cue effect and summarized the influencing factors of the retro-cue effect: memory items, maintenance interval time, interference in maint…

Negative emotional state modulates visual working memory in the late consolidation phase

2020

Although a considerable literature has grown up around the interactions between emotional state and visual working memory (VWM) performance, the mechanism underlying the impact of the negative emotional state on VWM remains unclear. The present study aimed to test whether the influence of emotional state is related to the early phase or late phase of VWM consolidation process. Across three experiments, we found that the negative emotional state did not affect VWM performance when the presentation time of stimuli was short. However, when the presentation time was long, the negative emotional state increased the VWM precision and reduced the VWM number. According to the two-phase model propos…

不同情绪面孔的视觉工作记忆表现差异 [The Performance Difference of Visual Working Memory between Various Emotional Faces]

2022

Among social-emotional stimuli, emotional faces occupy an important position, which specifically refer to human faces with certain facial expressions. The visual working memory is a limited workspace where information can be saved online and can be accessed and operated by advanced cognitive function during the maintenance period. A large number of behavioral and electrophysiological studies have shown that there are differences in visual working memory performance of different emotional faces. Specifically, angry faces can enhance the visual working memory performance; fearful faces may cause some damage to visual working memory; sad faces will impair face recognition encoding in visual wo…

Electrophysiological evidence supports the role of sustained visuospatial attention in maintaining visual WM contents

2019

Recent empirical and theoretical work suggests that there is a close relationship between visual working memory (WM) and visuospatial attention. Here, we investigated whether visuospatial attention was involved in maintaining object representations in visual WM. To this end, the alpha lateralization and contralateral delay activity (CDA) were analyzed as neural markers for visuospatial attention and visual WM storage, respectively. In the single-task condition, participants performed a grating change-detection task. To probe the role of visuospatial attention in maintaining WM contents, two color squares were presented above and below the fixation point during the retention interval, which …

La visualisation au service de l'analyse d'interactions Implémentation d'une forme de visualisation générique au sein d'un environnement d'analyse de…

2009

International audience; La visualisation de traces d'interactions est une composante importante de leur analyse dans le cadre de l'évaluation d'usages d'EIAH collaboratifs. Différentes présentations permettent en effet aux chercheurs de plus facilement explorer des corpus parfois très complexes. Dans cet article, nous examinons les besoins de chercheurs désirant visualiser et analyser des traces d'interaction et introduisons la notion de partition d'interaction, une forme générique de visualisation adaptée à ces besoins. Nous montrons de quelle manière cette fonction a été implémentée au sein de Tatiana, un environnement d'analyse de traces. En particulier, nous illustrons comment l'archite…

Positive Effects of Videogame Use on Visuospatial Competencies: The Impact of Visualization Style in Preadolescents and Adolescents

2019

Use of videogames (VGs) is almost ubiquitous in preadolescents' and adolescents' everyday life. One of the most intriguing research topics about positive effects of VG use is about the domain of visuospatial competencies. Previous research show that training with videogames enables children and adolescents to improve their scores in visuospatial tests (such as mental rotation of shapes and cubes), and that such training could overcome gender differences in these domains. Our study aimed at (1) verifying the positive effects of videogame use in the visuospatial domain both for male and female adolescents and preadolescents and (2) verifying whether the visualization style (2D or isometric 3D…

Lessico della cultura dialettale delle Madonie. 2. Voci di saggio

2011

Nella prospettiva di una sistematica ricognizione del patrimonio lessicale di un'area di grande interesse etnodialettale come quella madonita e dopo il volume sulla cultura alimentare tradizionale, il volume presenta oltre 3000 voci di saggio e numerose unità fraseologiche relative alla terminolgia connessa ai settori della cultura tradizionale. Le voci si riferiscono, in particolare, ai più significativi concetti dell'agricoltura e della pastorizia, ma presentano anche molti ambiti del mondo "naturale" (zoonimi, fitonimi, miconimi, meteoronimi). Il volume è corredato di carte linguistiche a colori sui principali tratti della cultura dialettale delle Madonie; il libro è arricchito da numero…
