Participants
The study was conducted in two samples. The first sample included 436
undergraduates (304 females, M = 19.37 (range: 18-45) years of
age) recruited from undergraduate psychology courses who received course
bonus credit. The replication sample included 477 undergraduates (314
females, M = 20.07 (range: 18-56) years of age). Both
samples were comprised of non-clinical individuals varying in
schizotypal traits. Participation criteria included: (1) normal
hearing; (2) normal or corrected-to-normal vision; (3) no history of
epilepsy; and (4) no history of major neurological or psychiatric
illness (e.g., traumatic brain injury, multiple sclerosis, autism,
bipolar disorder). Information regarding participants’ medication
intake was not collected. However, data were excluded if participants
indicated that they had a neurological disease or psychiatric problem.
Thus, we can infer that participants included in both samples were not
under the effects of antipsychotic medication. Protocols were approved
by the University of Nevada, Reno’s Institutional Review Board(#1395718) . Participants completed an online survey (Qualtrics)
including demographic questions, the SPQ-BR (Cohen et al., 2010), and
the PGT (Wilkins et al., 1984).
