Schizophrenia: Jumping to Conclusions

The forming and remaining of delusions is associated with the jumping to conclusions bias (Takeda, Nakataki, Ohta, Hamatani, Matsuura, and Ohmori, 2018). The bias of jumping to conclusions is often assessed with a probabilistic learning task. Takeda et al. (2018) investigated the association among JTC bias and neurocognition, confidence in decisions, and social cognition.

The authors concluded that JTC bias and confidence in decisions may be associated with different aspects of cognitive functioning. It was found that the jumping to conclusions bias was associated with neurocognition. In addition, the confidence in decisions was to be found to be associated with social cognition in schizophrenia patients (Takeda et al., 2018). The authors conclude finally that neurocognition and social cognition are two different aspects for schizophrenia vulnerability (Takeda et al., 2018).
