This study employs transcranial direct current stimulation (tDCS) to investigate the role of the orbitofrontal cortex (OFC) in processing gaze and arrow cues.
This study employs transcranial direct current stimulation (tDCS) to investigate the role of the orbitofrontal cortex (OFC) in processing gaze and arrow cues.To examine the distinct functions of the OFC in processing social versus non-social stimuli, participants were randomly assigned to one of three tDCS groups: anodal, cathodal, or sham. Following stimulation, all participants completed a spatial cueing task involving both gaze and arrow cues. Two stimulus onset asynchrony (SOA) conditions (200 ms and 600 ms) were implemented to investigate how timing modulates the processing of these cues within the rOFC.

| Reaction time to the judgment of the target location. | The primary analysis focused on the reaction times for judging the target location under each condition. | 1 hour |
| Measure | Description | Time Frame |
|---|---|---|
| Magnitude of the cueing effect | This index is derived by subtracting the congruent reaction time from the incongruent reaction time to quantify the magnitude of the cueing effect. | 1 hour |
