Schizophrenia patients exhibit impaired problem-solving skills, taking more steps and fewer optimal solutions on cognitive tasks. This deficit appears linked to executing intentions rather than motor speed.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Cognitive Psychology

Background:

  • Schizophrenia is a complex mental disorder.
  • Cognitive deficits are a core feature of schizophrenia.
  • Problem-solving abilities are often affected in schizophrenia.

Purpose of the Study:

  • To investigate problem-solving deficits in schizophrenia.
  • To assess planning and response times using the 3-D CTL Test.
  • To explore the relationship between cognitive performance and symptom severity.

Main Methods:

  • Thirty schizophrenia patients and 27 controls were tested.
  • The Three-Dimensional Computerised Tower of London Test (3-D CTL Test) was utilized.
  • Response latencies and planning times were analyzed.

Main Results:

  • Schizophrenia patients required more moves and fewer optimal solutions.
  • Patient response times were longer, but adjusted planning times were not significantly increased.
  • Inaccurate planning did not correlate with symptom type, but longer response times trended with negative symptoms.

Conclusions:

  • Schizophrenia is associated with a deficit in problem-solving activity.
  • This deficit may stem from difficulties in translating intentions into actions.
  • The problem-solving impairment appears independent of motor speed.
