The authors report 9 new experiments and reanalyze 3 published experiments that investigate factors affecting the time course of perceptual processing and its effects on subsequent decision making. Stimuli in letter-discrimination and brightness-discrimination tasks were degraded with static and dynamic noise. The onset and the time course of…

The present study investigated the ability to inhibit the processing of an irrelevant visual object while processing a relevant one. Participants were presented with 2 overlapping shapes (e.g., circle and square) in different colors. The task was to name the color of the relevant object designated by shape. Congruent or incongruent color words…

Nine studies showed a bidirectional link (a) between a global processing style and generation of similarities and (b) between a local processing style and generation of dissimilarities. In Experiments 1-4, participants were primed with global versus local perception styles and then asked to work on an allegedly unrelated generation task. Across…

The Stroop effect is psychology's classic measure gauging the selectivity of attention to individual attributes of complex stimuli. The emotional Stroop effect gauges the influence on behavior of threat and emotional stimuli. The former taps central/executive processes abstracted from particular stimulus contexts, whereas the latter taps automatic…

The effects of orthographic regularity and visual familiarity on internal coding and processing of visual stimuli were investigated in four experiments using college student subjects. Consistent effects of orthography on the activation of all codes were found. Familiarity influenced semantic more than phonetic codes. Implications for reading…
