Negative and Cognitive Symptoms of Schizophrenia01:30

Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Area of Science:

  • Neuroscience
  • Psychiatry
  • Cognitive Psychology

Background:

  • Simple reaction time tasks assess central nervous system processing and neurobehavioral performance.
  • Schizophrenia is associated with general slowness and attentional disengagement deficits.

Purpose of the Study:

  • To investigate attention disorders in schizophrenia using a simple reaction time task.
  • Clarify the specific features of attention deficits in schizophrenic patients.

Main Methods:

  • A simple reaction time task was administered to 54 individuals with schizophrenia and 61 healthy controls.
  • Participants were matched for age and gender; reaction times were measured using a response analyzer.

Main Results:

  • Schizophrenic patients demonstrated significantly slower reaction times compared to healthy controls (p<0.000).
  • This indicates a pronounced difficulty in sustaining attention among individuals with schizophrenia.

Conclusions:

  • The findings suggest inattentiveness in clinical settings and emotional disturbances in social interactions for schizophrenic patients.
  • Increased reaction times may stem from psychomotor poverty, disorganization, and reality distortion linked to frontal and temporal lobe dysfunction.
