When sharing a task with another person that requires turn taking, as in doubles games of

The magnitude of congruency effects, such as the flanker-compatibility effects, has been
found to vary as a function of the congruency of the previous trial. Some studies have …

if no interpersonal coordination is required. The present study asked whether coactors in a …

Social influences on action and memory are well established. However, it is unknown how

In research investigating Stroop or Simon effects, data are typically analyzed at the level of
mean response time (RT), with results showing faster responses for compatible than for …

A spatial compatibility effect (SCE) is typically observed in forced two-choice tasks in which a
spatially defined response (eg, pressing a left vs. a right key) has to be executed to a …
