Signal discrimination in the psychotic phenotype: increased sensory precision and reduced decision threshold associated with psychotic-like experiences.

Cognitive Neuropsychiatry July 1, 2025 Francesco Scaramozzino, Ryan Mckay, Nicholas Furl 1 citation

Psychotic-like experiences may reflect disrupted signal discrimination, whereby individuals overinterpret noisy sensory input as meaningful. Drawing on predictive coding accounts, we investigated whether increased sensory precision and reduced data-gathering relate to psychotic-like experiences in a signal discrimination task. We fitted drift-diffusion models to Random Dot Motion (RDM) task...

Shamanism and the psychosis continuum.

Behavioral and Brain Sciences January 2018 Robert M Ross, Ryan Mckay

Singh's cultural evolutionary theory of shamanism is impressive, but it does not explain why some people become shamans while others do not. We propose that individual differences in where people lie on a "psychosis continuum" could play an important causal role.
