Summary
Temporal overlap in cognitive processes, where partial stimulus information triggers responses early, sometimes occurs and sometimes doesn't. Distinguishing between perceptual selection and response control selection explains these variations in mental process overlap.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Psychophysiology
Background:
- Temporal overlap of cognitive processes involves partial stimulus information activating responses before full identification.
- Recent psychophysiological evidence shows this overlap is inconsistent.
- Understanding this inconsistency requires differentiating selection mechanisms.
Purpose of the Study:
- To explain the variable occurrence of temporal overlap in cognitive processes.
- To differentiate between selection of partial information for perception and for response control.
- To identify factors modulating this temporal overlap.
Main Methods:
- Analysis of psychophysiological measures related to cognitive processing.
- Theoretical distinction between perceptual and response control selection.
- Discussion of modulating mechanisms and factors.
Main Results:
- Temporal overlap is not constant; its occurrence depends on specific selection processes.
- Distinguishing between selection for perception versus response control is key.
- Various factors influence the availability and use of partial information.
Conclusions:
- The variability in temporal overlap of cognitive processes can be explained by differentiating selection for perception and selection for response control.
- Mechanisms and factors selectively influencing perceptual availability or use of partial information modulate this overlap.
