“A preliminary investigation of ERP components of attentional bias in anxious adults using temporospatial principal component analysis”: Correction to Gupta, Kujawa, & Vago, 2021.

Reports an error in "A preliminary investigation of ERP components of attentional bias in anxious adults using temporospatial principal component analysis" by Resh S. Gupta, Autumn Kujawa and David R. Vago (Journal of Psychophysiology, 2021, Vol 35[4], 223-236). In the article, the authors detected an error in the “Split-Half Reliability” section. The software used to perform the Spearman-Brown split-half correlation analyses outputted the Spearman rho, and not the Spearman-Brown, statistics. The authors re-calculated the Spearman-Brown split-half reliability values for all components, and it is excellent for all cases (Spearman-Brown range: .94–.98). All conclusions remain unchanged. (The following abstract of the original article appeared in record 2021-21536-001.) Threat-related attention bias is thought to contribute to the development and maintenance of anxiety disorders. Dot-probe studies using event-related potentials (ERPs) have indicated that several early ERP components are modulated by threatening and emotional stimuli in anxious populations, suggesting enhanced allocation of attention to threat and emotion at earlier stages of processing. However, ERP components selected for examination and analysis in these studies vary widely and remain inconsistent. The present study used temporospatial principal component analysis (PCA) to systematically identify ERP components elicited to face pair cues and probes in a dot-probe task in anxious adults. Cue-locked compon...
