Interventions

  • Low social feedback — BEHAVIORAL
    Social information is provided to participants signaling that the upcoming trial will be low in negative affect and cognitive effort.
  • High social feedback — BEHAVIORAL
    Social information is provided to participants signaling that the upcoming trial will be high in negative affect and cognitive effort.

Study Details

This study aims to assess the impact of social influence on direct neural recordings in human patients undergoing surgical treatment of epilepsy. 24 patients recruited from the Epilepsy Center at Dartmouth Health Medical Center (DHMC) will undergo electrode implantation throughout the brain to localize epileptogenic zones. Patients will be asked to rate their provider's warmth, competence, and other, similar traits associated with care-competency. They will then complete the picture-induced fear and math portions of the multimodal negative affect task (MNAT) during which iEEG is recorded.

Arms

  • Experimental: Random Order 1: Effects of social feedback on intracranial EEG
    Participants experience trials involving presentation of negative affective stimuli and an effort-demanding cognitive task. Trials are preceded by high or low social cues in random order.
  • Experimental: Random Order 2: Effects of social feedback on intracranial EEG
    Participants experience trials involving presentation of negative affective stimuli and an effort-demanding cognitive task. Trials are preceded by high or low social cues in random order.

Primary Outcome Measure

Negative affect ratings [ Time Frame: Ratings are made 3 to 10 seconds after experiencing each stimulus presented during task performance. ]
