Jumping to conclusions bias : assessment of hasty data-gathering in normal population

Abstract

The study investigated data-gathering in context of delusional reasoning where we examined an enhanced tendency to decrease data-gathering in respect to scores on sub-clinical assessment of psychotic experiences. The study examined three proposed accounts of this phenomena, liberal acceptance, hyper salience, and noise – whereby calculation of the three parameters approximating these accounts was used to see which of them undermined the tendency to a decrease in data-gathering. In current sample, hyper salience was the proposed account that was associated to a decreased tendency of data-gathering. The decrease in data-gathering was specifically associated to sub-clinical positive symptoms. In addition, predictors of sub-clinical positive symptoms was systematizing traits and sub-clinical negative symptoms.
