Extended testing with the dot-probe task increases test-retest reliability and validity

Student Database

Author: Aday, Jacob S.; Carlson, Joshua M. Description: The dot-probe task is used to measure attentional biases toward threat. However, the test-retest reliability and validity of the task have been called into question. No studies to date have included an extended number of testing sessions or tailored the task to individual participants by incorporating self-relevant stimuli-doing so may improve reliability. Here, participants provided 10 words that caused them anxiety and 10 neutral words which were incorporated into a dot-probe task for 6 sessions. The test-retest reliability of their bias indices…

Threat-related attentional bias in anxious and nonanxious individuals: a meta-analytic study

Student Database

Author: Bar-Haim, Yair; Lamy, Dominique; Pergamin, Lee; Bakermans-Kranenburg, Marian J.; van IJzendoorn, Marinus H. Description: This meta-analysis of 172 studies (N = 2,263 anxious, N = 1,768 nonanxious) examined the boundary conditions of threat-related attentional biases in anxiety. Overall, the results show that the bias is reliably demonstrated with different experimental paradigms and under a variety of experimental conditions, but that it is only an effect size of d = 0.45. Although processes requiring conscious perception of threat contribute to the bias, a significant bias is also observed with stimuli…
