There is evidence that people with schizophrenia have difficulties in some (recently evolved) competencies for processing social information. However, a case can be made that vulnerabilities can also lie in (previously evolved) threat and safeness processing systems. Evolutionary models may need to consider interactions between genetic sensitivities, early experiences of threat/safeness, and later cognitive vulnerabilities. Psychological treatments must address issues of experienced threat and safeness before working on more cognitive competencies.
