Working memory load predicts visual search efficiency: Evidence from a novel pupillary response paradigm.
An observer's pupil dilates and constricts in response to variables such as ambient and focal luminance, cognitive effort, the emotional stimulus content, and working memory load. The pupil's memory load response is of particular interest, as it might be used for estimating observers' memory load while they are performing a complex task, without adding an interruptive and confounding memory tes...
متن کاملMemory load affects visual search processes without influencing search efficiency
Participants' eye-movements were monitored while they searched for a target among a varying number of distractors either with or without a concurrent memory load. Consistent with previous findings, adding a memory load slowed response times without affecting search slopes; a finding normally taken to imply that memory load affects pre- and/or post-search processes but not the search process its...
متن کاملFinding memory in search: the effect of visual working memory load on visual search.
There is now substantial evidence that during visual search, previously searched distractors are stored in memory to prevent them from being reselected. Studies examining which memory resources are involved in this process have indicated that while a concurrent spatial working memory task does affect search slopes, depleting visual working memory (VWM) resources does not. In the present study, ...
متن کاملSearching while loaded: Visual working memory does not interfere with hybrid search efficiency but hybrid search uses working memory capacity.
In "hybrid search" tasks, such as finding items on a grocery list, one must search the scene for targets while also searching the list in memory. How is the representation of a visual item compared with the representations of items in the memory set? Predominant theories would propose a role for visual working memory (VWM) either as the site of the comparison or as a conduit between visual and ...
متن کاملEffects of memory load on visual search.
It remains unclear how memory load affects attentional processes in visual search (VS). No effects, as well as beneficial and detrimental effects of memory load, have been found in this type of task. The main goal of the present research was to explore whether memory load has a modulating effect on VS by means of a different attentional set induced by the order of trials (mixed vs. blocked) and...
