  • Title: Jumping to conclusions and the continuum of delusional beliefs.
    Author: Warman DM, Lysaker PH, Martin JM, Davis L, Haudenschield SL.
    Journal: Behav Res Ther; 2007 Jun; 45(6):1255-69. PubMed ID: 17052687.
    Abstract:
    The present study examined the jumping to conclusions reasoning bias across the continuum of delusional ideation by investigating individuals with active delusions, delusion prone individuals, and non-delusion prone individuals. Neutral and highly self-referent probabilistic reasoning tasks were employed. Results indicated that individuals with delusions gathered significantly less information than delusion prone and non-delusion prone participants on both the neutral and self-referent tasks, (p<.001). Individuals with delusions made less accurate decisions than the delusion prone and non-delusion prone participants on both tasks (p<.001), yet were more confident about their decisions than were delusion prone and non-delusion prone participants on the self-referent task (p=.002). Those with delusions and those who were delusion prone reported higher confidence in their performance on the self-referent task than they did the neutral task (p=.02), indicating that high self-reference impacted information processing for individuals in both of these groups. The results are discussed in relation to previous research in the area of probabilistic reasoning and delusions.
