Effects of updating visuo-spatial working memory in early visual cortex

Spatial working memory effects in early visual cortex.

The present study investigated how spatial working memory recruits early visual cortex. Participants were required to maintain a location in working memory while changes in blood oxygen level dependent (BOLD) signals were measured during the retention interval in which no visual stimulation was present. We show working memory effects during the retention period in early visual cortex which were...

Visuo-spatial Working Memory

The Effects of Spark Training on Visual-Spatial Working Memory Operation in Children with Mental Retardation

Introduction: Mental retarded children who receive a wide range of health services, representing more than two percent of the population. Mental retardation is associated with significant constraints on mental performance and adaptive behavior as well as perceptual and practical skills. According to the studies, one of the important tools that can affect cognitive abilities, such as memory, is ...

Updating visual–spatial working memory during object movement

Working memory enables temporary maintenance and manipulation of information for immediate access by cognitive processes. The present study investigates how spatial information stored in working memory is updated during object movement. Participants had to remember a particular location on an object which, after a retention interval, started to move. The question was whether the memorized locat...

The time course of visuo-spatial working memory updating revealed by a retro-cuing paradigm

We investigated the influence of non-cued working memory representations on further information processing. A retro-cue indicated if items on the left or right side of a previous memory array remained relevant. Subsequently, a central probe item was presented with a varying stimulus onset asynchrony (SOA: 300, 400, 600, 1,000, 1,800 ms). Participants had to state whether this stimulus was shown...
