The aim of the present study was to compare visuospatial working memory performance in 18 individuals with Williams syndrome WS and 18 typically developing TD children matched for nonverbal mental age. Two aspects were considered: task presentation format i. Our results showed that individuals with WS performed less well than TD children in passive spatial-simultaneous tasks, but not in passive spatial-sequential tasks. The former's performance was also worse in both active tasks. These findings suggest an impairment in the spatial-simultaneous working memory of individuals with WS, together with a more generalized difficulty in tasks requiring information storage and concurrent processing, as seen in other etiologies of intellectual disability.

The hippocampus: Beyond recognition memory View all 10 Articles. In this review, we will discuss the idea that the hippocampus may be involved in both memory and perception, contrary to theories that posit functional and neuroanatomical segregation of these processes. This suggestion is based on a number of recent neuropsychological and functional neuroimaging studies that have demonstrated that the hippocampus is involved in the visual discrimination of complex spatial scene stimuli. We argue that these findings cannot be explained by long-term memory or working memory processing or, in the case of patient findings, dysfunction beyond the medial temporal lobe MTL. Instead, these studies point toward a role for the hippocampus in higher-order spatial perception.
Several studies have found that musicians perform better than nonmusicians in memory tasks, but this is not always the case, and the strength of this apparent advantage is unknown. Here, we conducted a meta-analysis with the aim of clarifying whether musicians perform better than nonmusicians in memory tasks. The selected studies involved two groups of participants: young adult musicians and nonmusicians. All the studies included memory tasks loading long-term, short-term or working memory that contained tonal, verbal or visuospatial stimuli. Three meta-analyses were run separately for long-term memory, short-term memory and working memory. We collected 29 studies, including 53 memory tasks. To further explore the data, we included a moderator the type of stimulus presented, i.
Baddeley's model of working memory is a model of human memory proposed by Alan Baddeley and Graham Hitch in , in an attempt to present a more accurate model of primary memory often referred to as short-term memory. Working memory splits primary memory into multiple components, rather than considering it to be a single, unified construct. This model is later expanded upon by Baddeley and other co-workers to add a fourth component, and has become the dominant view in the field of working memory. However, alternative models are developing, providing a different perspective on the working memory system. The phonological loop stores verbal content, whereas the visuo-spatial sketchpad caters to visuo-spatial data.
In cognitive psychology and neuroscience , spatial memory is a form of memory responsible for the recording of information about one's environment and spatial orientation. For example, a person's spatial memory is required in order to navigate around a familiar city, just as a rat's spatial memory is needed to learn the location of food at the end of a maze. It is often argued that in both humans and animals, spatial memories are summarized as a cognitive map. Spatial memory has representations within working, short-term memory and long-term memory.
A visual short-term memory task was more strongly disrupted by visual than spatial interference, and a spatial memory task was simultaneously more strongly disrupted by spatial than visual interference.
Она подавляла его своей красотой, и всякий раз, когда он оказывался рядом, язык у него заплетался. Сейчас она держалась подчеркнуто сдержанно, и это пугало его еще сильнее. - Так в чем же проблема, Фил? - спросил Стратмор, открывая холодильник.
Должно быть, Танкадо держится в стороне от таких вещей, но всем известно, что он гений. Это культовая фигура, икона в мире хакеров. Если Танкадо говорит, что алгоритм не поддается взлому, значит, так оно и .
Хейл не проронил ни слова. Казалось, вспыхнувшая на его глазах перепалка абсолютно его не касается. Очевидно, Стратмор вдруг задумался: .
