This study compares the signal detection to exponential race model useful in explaining various aspects of visual attention. Both models explain multielement displays that affect the entry of items in the visual short-term memory (VSTM) (Larsen, Markussen, & Bundesen, 2020). Specifically, bias set size of display, pertinence, and duration of exposure all affect the item and the number that enters the VSTM. The exponential race model is based on the theory of visual attention (TVA) and explains the entry of items in VSTM involves competition at processing race and in an exponentially distributed processing time (Larsen et al., 2020). It is also based on the power-law generalization of the sample size model (SSPL) that explains that the target’s sensitivity is affected by the duration of exposure and the power function of the set size (Larsen et al., 2020). The study to compare the two models is based on a new experiment that used the Gabor patches and letters and by use of data from previously published
