Editing Visual short-term memory (section)

==The function of visual short-term memory representations==
VSTM is thought{{by whom|date=March 2019}} to be the visual component of the working memory system, and as such it is used as a buffer for temporary information storage during the process of naturally occurring tasks. But what naturally occurring tasks actually require VSTM? Most work on this issue has focused on the role of VSTM in bridging the sensory gaps caused by saccadic eye movements. These sudden shift of gaze typically occur 2–4 times per second, and vision is briefly suppressed while the eyes are moving. Thus, the visual input consists of a series of spatially shifted snapshots of the overall scene, separated by brief gaps. Over time, a rich and detailed long-term memory representation is constructed from these brief glimpses of the input, and VSTM is thought{{by whom|date=March 2019}} to bridge the gaps between these glimpses and to allow the relevant portions of one glimpse to be aligned with the relevant portions of the next glimpse. Both spatial and object VSTM systems may play important roles in the integration of information across eye movements. Eye movements are also affected by VSTM representations. The constructed representations held in VSTM can affect eye movements even when the task does not explicitly require eye movements: the direction of small [[microsaccade]]s point towards the location of objects in VSTM.<ref>{{cite journal |last1=Martinez-Conde |first1=S |last2=Alexander |first2=R |title=A gaze bias in the mind's eye |journal=Nature Human Behaviour |date=2019 |volume=3 |issue=5 |pages=424–425 |doi=10.1038/s41562-019-0546-1 |pmid=31089295 |s2cid=71148025 }}</ref>
