Visual Working Memory Capacity Can Be Increased by Training on Distractor Filtering Efficiency [PDF]

open access: yesFrontiers in Psychology, 2017
It is generally considered that working memory (WM) capacity is limited and that WM capacity affects cognitive processes. Distractor filtering efficiency has been suggested to be an important factor in determining the visual working memory (VWM) capacity of individuals.

Previewing distractors reduces efficiency of visual processing at previewed locations

open access: yesVision Research, 2013
Visual marking refers to the phenomenon in which old items in a visual search are excluded from the search when new items appear in the visual field. Visual marking may result from inhibition of irrelevant information at the location of old items before new items appear.

Perceptual load vs. dilution: the roles of attentional focus, stimulus category, and target predictability

open access: yesFrontiers in Psychology, 2013
Many studies have shown that increasing the number of neutral stimuli in a display decreases distractor interference. This result has been interpreted within two different frameworks; a perceptual load account, based on a reduction in spare resources ...

The interaction of target-distractor similarity and visual search efficiency for basic features

open access: yesJournal of Vision, 2017
Visual search efficiency is commonly measured by the relationship between subject response time (RT) and display set size. Basic features are visual features for which a singleton target can be found efficiently (RT independent of set size), a situation commonly referred to as pop-out.

Template-to-distractor distinctiveness determines visual search efficiency.

open access: yes, 2020
Historically, it has been found that more veridical target templates produce faster and more accurate target match decisions during visual search. However, recent evidence suggests that the template may actually be more optimal when “off-veridical” if it

Distractor inhibition: Evidence from lateralized readiness potentials [PDF]

open access: yes, 2015
peer reviewedThe present study investigated distractor inhibition on the level of stimulus representation. In a sequential distractor-to-distractor priming task participants had to respond to target letters flanked by distractor digits. Reaction time and

Item analysis and optimizing multiple-choice questions for a viable question bank in ophthalmology: A cross-sectional study

open access: yesIndian Journal of Ophthalmology, 2021
Purpose: Multiple-choice questions (MCQs) are useful in assessing student performance, covering a wide range of topics in an objective way. Its reliability and validity depend upon how well it is constructed. Defective Item detected by item analysis must

Distractor dwelling, skipping, and revisiting determine target absent performance in difficult visual search

open access: yesFrontiers in Psychology, 2016
Some targets in visual search are more difficult to find than others. In particular, a target that is similar to the distractors is more difficult to find than a target that is dissimilar to the distractors.
