Inhibition of return (IOR) is a delay in responding to cued locations. This study found IOR is amplified with simple responses, but not affected by response complexity in choice tasks.
Area of Science:
- Cognitive Neuroscience
- Psychology
Background:
- Inhibition of return (IOR) describes delayed responses to previously cued locations.
- IOR is theorized to involve attentional mechanisms or cue-evoked response inhibition.
Purpose of the Study:
- To investigate the role of response requirements in IOR.
- To differentiate between attentional and response-related contributions to IOR using EEG.
Main Methods:
- Event-related EEG activity was recorded during a task involving simple, compatible, and incompatible choice responses.
- Participants responded to targets presented at cued and uncued locations.
Main Results:
- IOR was significantly amplified with simple responses.
- No significant difference in IOR was observed between compatible and incompatible choice responses.
- Attention-related electroencephalography (EEG) correlates remained consistent across different cue-target onset asynchronies.
Conclusions:
- Response selection processes do not appear to contribute to IOR in manual choice response tasks.
- The findings suggest that IOR is primarily driven by attentional mechanisms rather than response-related factors.
