Individuals with schizotypy show deficits in sustained attention, a key cognitive function. This subtle attention impairment was observed regardless of anxiety or depression levels in the study.

Area of Science:

  • Cognitive Psychology
  • Psychopathology Research
  • Neuroscience

Background:

  • Schizotypy is considered a potential precursor to schizophrenia, characterized by subclinical psychotic-like experiences.
  • Attention deficits are a well-documented feature in individuals diagnosed with schizophrenia.
  • Understanding cognitive functioning in schizotypy may offer insights into the early stages of psychosis.

Purpose of the Study:

  • To investigate sustained attention abilities in individuals with schizotypy compared to healthy controls.
  • To determine if anxiety and depression levels influence sustained attention performance in schizotypal individuals.
  • To explore the utility of the psychometric high-risk strategy in psychopathology research.

Main Methods:

  • A sample of 32 schizotypic and 43 normal control subjects was recruited from a university population.

  • Schizotypy was assessed using the Perceptual Aberration Scale.
  • Sustained attention was measured using the Continuous Performance Test-Identical Pairs (CPT-IP).

    • Main Results:

    • Schizotypic subjects demonstrated significantly poorer sustained-attention performance compared to control subjects, indicated by lower d' and overall hit rates.
    • Sustained attention deficits in schizotypy were not significantly correlated with self-reported anxiety or depression.
    • The findings suggest a subtle, specific deficit in sustained attention among individuals with schizotypy.

    Conclusions:

    • The study provides evidence for a subtle sustained-attention deficit in schizotypy, independent of anxiety and depression.
    • These findings align with attention research in schizophrenia and individuals at clinical high risk for the disorder.
    • The psychometric high-risk strategy is a valuable approach for studying the cognitive underpinnings of psychopathology.
