Using reliability and item analysis to evaluate a teacher-developed test in educational measurement and evaluation

Cogent Education, 2017
Item analysis is essential in improving items which will be used again in later tests; it can also be used to eliminate misleading items in a test. The study focused on item and test quality and explored the relationship between difficulty index (p-value)

Enhancing Biochemistry Assessments: Our Experience with MCQ Validation in Punjab [PDF]

Indian Journal of Medical Biochemistry
Background and aim: Item analysis of multiple-choice questions (MCQs) is a widely accepted method to ensure their quality and effectiveness. Key indices used in this process include the difficulty index (DIF I), discrimination index (DI), and distractor ...

“Two Minds Don’t Blink Alike”: The Attentional Blink Does Not Occur in a Joint Context [PDF]

, 2018
Typically, when two individuals perform a task together, each partner monitors the other partners' responses and goals to ensure that the task is completed efficiently. This monitoring is thought to involve a co-representation of the joint goals and task,

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

Journal 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.

Eye tracking the face in the crowd task: why are angry faces found more quickly? [PDF]

PLoS ONE, 2014
Among a crowd of distractor faces, threatening or angry target faces are identified more quickly and accurately than are nonthreatening or happy target faces, a finding known as the "face in the crowd effect." Two perceptual explanations of the effect ...

Investigation of a Model-Based Working Memory Training With and Without Distractor Inhibition and Its Comparative Efficacy: A Randomized Controlled Trial on Healthy Old Adults

Frontiers in Aging Neuroscience, 2021
Background: Various working memory (WM) trainings have been tested, but differences in experimental designs, the lack of theoretical background, and the need of identifying task-related processes such as filtering efficiency limit conclusions about their

Effects of transcranial direct current stimulation over left dorsolateral pFC on the attentional blink depend on individual baseline performance [PDF]

, 2015
Selection mechanisms that dynamically gate only relevant perceptual information for further processing and sustained representation in working memory are critical for goal-directed behavior.

Efficient Attentional Selection Predicts Distractor Devaluation: Event-related Potential Evidence for a Direct Link between Attention and Emotion [PDF]

Journal of Cognitive Neuroscience, 2007
Abstract Links between attention and emotion were investigated by obtaining electrophysiological measures of attentional selectivity together with behavioral measures of affective evaluation. Participants were asked to rate faces that had just been presented as targets or distractors in a visual search task.

Target–distractor similarity predicts visual search efficiency but only for highly similar features

Attention, Perception, & Psychophysics
A major constraining factor for attentional selection is the similarity between targets and distractors. When similarity is low, target items can be identified quickly and efficiently, while high similarity can incur large costs on processing speed. Models of visual search contrast a fast, efficient parallel stage with a slow serial processing stage ...
