Exploring Modality Compatibility in the Response-Effect Compatibility Paradigm

Exploring Modality Compatibility in the Response-Effect Compatibility Paradigm

According to ideomotor theory, action planning is based on anticipatory perceptual representations of action-effects. This aspect of action control has been investigated in studies using the response-effect compatibility (REC) paradigm, in which responses have been shown to be facilitated if ensuing perceptual effects share codes with the response based on dimensional overlap (i.e., REC). Addit...

Joint response-effect compatibility.

When performing jointly on a task, human agents are assumed to represent their coactor's share of this task, and research in various joint action paradigms has focused on representing the coactor's stimulus-response assignments. Here we show that the response-effect (R-E) contingencies exploited by a coactor also affect performance, and thus might be represented as if they were used by oneself....

Verbal response-effect compatibility.

Ideomotor theory states that motor responses are activated by an anticipation of their sensory effects. We assumed that anticipated effects would produce response-effect (R-E) compatibility when there is dimensional overlap of effects and responses. In a four-choice task, visual digit stimuli called for verbal responses (color names). Each response produced a written response-effect on the scre...

Stimulus-Response Compatibility Is Information-Action Compatibility

The neural effect of stimulus-response modality compatibility on dual-task performance: an fMRI study.

Recent fMRI studies suggest that the inferior frontal sulcus (IFS) is involved in the coordination of interfering processes in dual-task situations. The present study aims to further specify this assumption by investigating whether the compatibility between stimulus and response modalities modulates dual-task-related activity along the IFS. It has been shown behaviorally that the degree of inte...
