Brief Summary
This clinical trial will examine whether transcranial magnetic stimulation (TMS), a noninvasive form of brain stimulation, can influence social cognition, cognitive processing, and brain function in adults with elevated psychopathic traits. The study will also evaluate the safety and feasibility of delivering TMS in this population. Participants will be randomly assigned to receive either active TMS or sham (placebo-like) TMS. The study will compare outcomes between participants receiving active versus sham TMS and will evaluate changes from before to after TMS exposure. Participants will:
- Complete a baseline magnetic resonance imaging (MRI) brain scan.
- Receive three single-session TMS interventions.
- Complete a post-intervention MRI brain scan.
- Complete assessments of social cognition.
- Complete assessments of cognitive processing. The primary objectives are to determine whether TMS can influence social cognition, cognitive processing, and functional brain organization and connectivity in adults with elevated psychopathic traits.

Outcome Measures
Primary Outcomes (2)
Social Cognition Task Battery Performance
Performance on a social cognition task battery assessing facial emotion recognition (Emotion Recognition Task), perspective taking (Visual Perspective Taking Task), theory of mind (Movie Assessment of Social Cognition Task), and social decision-making (Altruistic/Antisocial game). Accuracy and reaction time will be analyzed using mixed-effects models to compare active stimulation versus sham stimulation across tasks. Higher accuracy values indicate better performance, whereas lower reaction times indicate better performance.
within 10 minutes after the intervention.
Serial and Parallel Cognitive Processing Task Performance
Performance on the Miller serial/parallel cognitive processing task. Trial-level accuracy and/or reaction time will be analyzed using mixed-effects models to compare active stimulation versus sham stimulation across serial and parallel processing conditions.
within 10 minutes after the intervention.
Secondary Outcomes (1)
Change in Resting-State Functional Connectivity
From the date of baseline fMRI until the first TMS session, assessed 2 times (baseline and post-TMS) up to 2 months after the baseline session. Post-TMS fMRI scan will be conducted within 30 minutes after the intervention.
Study Arms (3)
active dlPFC sham TPJ
ACTIVE COMPARATORSubjects in this group will receive active continuous theta burst stimulation (cTBS) to the individually defined region of the dlPFC and sham to the TPJ.
active TPJ sham dlPFC
ACTIVE COMPARATORSubjects in this group will receive active intermittent theta burst stimulation to the individually defined region of the TPJ and sham to the dlPFC.
sham
SHAM COMPARATORSubjects in this group will receive sham stimulation to the dlPFC and TPJ.
Interventions
Continuous theta burst stimulation (cTBS) will be delivered using transcranial magnetic stimulation (TMS) targeting the right dorsolateral prefrontal cortex (dlPFC). cTBS is a patterned form of repetitive TMS designed to modulate neural activity within targeted brain networks involved in cognitive control and social cognition. Stimulation targets will be individualized using participant-specific neuroimaging data.
Sham transcranial magnetic stimulation will be delivered using procedures designed to mimic the sensory experience of active stimulation without producing the intended neuromodulatory effects. Stimulation targets and study procedures will mirror those used in the active intervention arms.
Intermittent theta burst stimulation (iTBS) will be delivered using transcranial magnetic stimulation (TMS) targeting the right temporoparietal junction (TPJ). iTBS is a patterned form of repetitive TMS designed to modulate neural activity within targeted brain networks involved in social cognition and perspective taking. Stimulation targets will be individualized using participant-specific neuroimaging data
