Effort during visual search and counting: insights from pupillometry.
We investigated the processing effort during visual search and counting tasks using a pupil dilation measure. Search difficulty was manipulated by varying the number of distractors as well as the heterogeneity of the distractors. More difficult visual search resulted in more pupil dilation than did less difficult search. These results confirm a link between effort and increased pupil dilation. ...
متن کاملPupil Dilation Co-Varies with Memory Strength of Individual Traces in a Delayed Response Paired-Associate Task
Studies on cognitive effort have shown that pupil dilation is a reliable indicator of memory load. However, it is conceivable that there are other sources of effort involved in memory that also affect pupil dilation. One of these is the ease with which an item can be retrieved from memory. Here, we present the results of an experiment in which we studied the way in which pupil dilation acts as ...
متن کاملDoes retrieval require effort? Effects of memory strength on pupil dilation
The current study investigates the relation between retrieval effort and the relative memory strength of mentally stored information. A previous pupillary study by Magliero (1983) showed that encoding effort reacts to the recency effect but no studies have linked effort as measured by pupillary dilation to the frequency effect. In the current study, phasic pupil dilation of 15 participants was ...
متن کاملPupil dilation reveals top-down attentional load during spatial monitoring.
It has long been known that the diameter of human pupil enlarges with increasing effort during the execution of a task. This has been observed not only for purely mechanical effort but also for mental effort, as for example the computation of arithmetic problems with different levels of difficulty. Here we show that pupil dilation reflects changes in visuospatial awareness induced by attentiona...
متن کاملThe Impact of Auditory Spectral Resolution on Listening Effort Revealed by Pupil Dilation.
OBJECTIVES This study measured the impact of auditory spectral resolution on listening effort. Systematic degradation in spectral resolution was hypothesized to elicit corresponding systematic increases in pupil dilation, consistent with the notion of pupil dilation as a marker of cognitive load. DESIGN Spectral resolution of sentences was varied with two different vocoders: (1) a noise-chann...
