TL;DR: In this article, the authors make theoretical comparisons among five coefficients (Cronbach's α, Revelle's β, McDonald's ω� h�, and two alternative conceptualizations of reliability) and demonstrate formally their nonequivalence.

TL;DR: In this article, seven techniques for estimating ωh were compared in a series of simulated data sets and the results suggest that alpha and methods based on either the first unrotated principal factor or component should be rejected as estimates of ω h.

TL;DR: A visual search task with a lexical decision component was used to differentiate between attentional interference and facilitation, and high PTSD participants showed increased interference to trauma-related words relative to Low PTSD participants and no evidence was found for facilitated detection of threatening stimuli in PTSD.

TL;DR: In this paper, the influence of attentional demands, stimulus properties, and mode of response on perceptual asymmetries for global and local perception was examined for divided-than-focused-attention tasks and stimuli in which local and global levels were equally salient compared with those with greater global than local saliency.

TL;DR: No evidence was found for facilitated detection of threatening stimuli in PTSD, and attentional interference and facilitation were distinguished.
