Delusion-like thinking is associated with lower individual alpha peak frequency

Schizophrenia and schizotypy are understood to lie along a continuum of neurophysiological and cognitive features, yet the specific neural markers bridging clinical and subclinical manifestations have remained underexplored. In our study (N = 318), we found that reduced Individual Alpha Frequency (IAF)—previously established as a neural marker in schizophrenia—features magical thinking trait in schizotypy. This finding broadens the relevance of IAF to subclinical populations linking it to delusion-like thinking in schizotypy and suggests its potential as a transdiagnostic indicator across the schizophrenia spectrum.
