People sometimes engage in “jumping to conclusions,” a reasoning bias where a decision is made without having an adequate amount of information to make a proper decision. New research indicates that JTC directly impacts cognitive functioning.
Susana Ochoa, PhD, of the Sant Joan de Deu Research Foundation in Barcelona, Spain, and colleagues conducted a study to assess the relationship between three tasks differing in complexity and concept which assess JTC and cognitive functioning in a sample of people with schizophrenia (n=43) and healthy participants (n=57).
Participants were measured with a cognition battery including executive function, verbal memory, and IQ. In addition, patients with schizophrenia were evaluated on their psychotic and affective symptoms and the healthy participants on proneness to hallucinations and delusions.
There was a clear relationship between JTC and cognitive functioning, particularly in working memory, verbal memory, and cognitive processing speed both in people with schizophrenia and in healthy participants, the researchers reported in Schizophrenia Research. However, there was no relationship in the emotional task of JTC.
“Our results suggest that diverse psychological interventions such as cognitive remediation, cognitive behavioral therapy and meta-cognitive training might contribute to reducing JTC bias,” the researchers concluded, adding hallucinations in people with schizophrenia is related to JTC.
‘Jumping to conclusions’ (JTC) is a reasoning bias consisting of a tendency to take a decision without having enough information about an event. It has been related to the presence of delusions. The aim of the present study was to assess the relationship between three tasks differing in complexity and concept which assess JTC and cognitive functioning in a sample of people with schizophrenia and healthy participants.
