Unstable Belief Formation and Slowed Decision-making: Evidence That the Jumping-to-Conclusions Bias in Schizophrenia Is Not Linked to Impulsive Decision-making.

ABSTRACT:

Jumping-to-conclusions (JTC) is a prominent reasoning bias in schizophrenia (SCZ).

Participants performed a probabilistic beads task. To test the association of JTC with measures of delusions (Positive and Negative Syndrom
