What is the purpose of this trial?

The purpose of this clinical trial is to investigate the effects of multiple sessions of transcranial direct current stimulation (tDCS) delivered while participants complete tasks that target social learning with high functioning adults with ASD and/or high traits of ASD. The main question it aims to answer is: What are the effects of multiple sessions of active compared to sham tDCS, with tDCS simultaneously paired with social learning tasks, from employing a within-subject, cross-over randomized controlled trial design? Participants will: * Complete a randomly assigned block of 5 sessions of active and a block of 5 sessions of sham tDCS, with a four-week break occurring between the two blocks. * Complete social learning tasks simultaneously during receipt of tDCS at each session (whether receiving active or sham tDCS). * Complete behavioral, physiological, and electrophysiological testing before and after each block of active or sham tDCS. * Complete a social validity questionnaire after completion of the study.

What Are the Treatments Tested in This Trial?

Interventions

• Anodal tDCS + Social Learning
• Placebo Anodal tDCS + Social Learning

Trial Overview The study tests if brain stimulation (tDCS) paired with social learning tasks can help adults with ASD. Participants will undergo two blocks of five sessions each: one block using active tDCS and another using sham (placebo) tDCS, separated by a four-week break. Their behavior, physiology, and brain activity will be measured before and after each block.

How Is the Trial Designed?

Group I: Anodal tDCS + Social Learning Experimental Treatment 1 Intervention

In this arm, participants will undergo 5 sessions of 30 minutes anodal tDCS combined with social learning tasks on consecutive weekdays.

Group II: Placebo anodal tDCS + Social Learning Placebo Group 1 Intervention

In this arm, participants will undergo 5 sessions of 30 minutes placebo anodal tDCS combined with social learning tasks on consecutive weekdays.
