Diffusion models have become essential for describing the performance and statistics of reaction times in human decision making. Despite their success, it is not known how to evaluate decision confidence from them. I introduce a broader class of models consisting of two partially correlated neuronal integrators with arbitrarily time-varying decision boundaries that allow a natural description of confidence. The dependence of decision confidence on the state of the losing integrator, decision time, time-varying boundaries, and correlations is analytically described. The marginal confidence is computed for the half-anticorrelated case using the exact solution of the diffusion process with constant boundaries and compared to that of the independent and completely anticorrelated cases.

How do human observers determine their degree of belief of being correct in a visual discrimination decision, i.e. their confidence? According to prominent theories of confidence, the quality of stimulation should be positively related to confidence in correct decisions and negatively to confidence in incorrect decisions. However, in a backwards-masked orientation discrimination task with varying stimulus-onset asynchrony (SOA), we observed that confidence in incorrect decisions increased with stimulus quality as well. Model fitting to decision and confidence data revealed that the best explanation for the present data was the new weighted evidence and visibility model, according to which confidence is determined by evidence about the orientation as well as the general visibility of the stimulus. Signal detection models, post-decisional accumulation models, two channel models, and decision-time based models were all unable to explain the pattern of confidence as a function of SOA and decision correctness. We suggest that the metacognitive system combines several cues to being correct in visual discrimination decisions to calculate decision confidence.

This study deals with the sociocognitive organization of the self-schema in alcoholic patients. It was aimed at understanding how the self-schema takes shape within the framework of social judgments known to be determinants of personality. Alcoholic subjects were interviewed twice, once during their first consultation for treatment and then again four months later after completion of treatment. Our approach was derived directly from the methodology used by Markus (1977) and Clemmey & Nicassio (1997) in their studies on the self-schema. The subjects had to perform three tasks that required manipulating personality traits with positive and negative connotations (a self-description task in which decision time was measured, an autobiographical task, and a recall task). The results of the first interview showed that 1. in their self-descriptions, alcoholics took more time than control subjects both to accept positive traits and to reject negative ones; 2. unlike control subjects, alcoholics considered more negative traits to be self-descriptive than positive traits, and 3. unlike controls, alcoholics recalled more negative traits than positive ones. By the second interview, the results for the alcoholic subjects on the autobiographical and recall tasks had changed: 1. they now described themselves more positively and less negatively than on the first meeting; 2. they recalled a marginally greater number of positive traits and a significantly smaller number of negative traits, and 3. the differences between the alcoholics and controls indicated an improvement in the alcoholics' self-perceptions.

Research using the Implicit Association Test (IAT) has shown that names labeled as Caucasian elicit more positive associations than names labeled as non-Caucasian. One interpretation of this result is that the IAT measures latent racial prejudice. An alternative explanation is that the result is due to differences in in-group/out-group membership. In this study, we conducted three different IATs: one with same-race Dutch names versus racially charged Moroccan names; one with same-race Dutch names versus racially neutral Finnish names; and one with Moroccan names versus Finnish names. Results showed equivalent effects for the Dutch-Moroccan and Dutch-Finnish IATs, but no effect for the Finnish-Moroccan IAT. This suggests that the name-race IAT-effect is not due to racial prejudice. A diffusion model decomposition indicated that the IAT-effects were caused by changes in speed of information accumulation, response conservativeness, and non-decision time.
