The effect of incentivization on the conjunction fallacy in judgments: a meta-analysis.

The conjunction fallacy is a classical judgment bias that was argued to be a robust cognitive illusion insensitive to the positive effect of incentivization. We conducted a meta-analysis of the literature (n = 3276) and found that although most studies did not report a significant effect of incentivization, the results across studies show a significant positive effect for incentivization, d = 0.19, with an odds ratio of 1.

Choice behavior in autistic adults: What drives the extreme switching phenomenon?

Background: Previous studies reported that autistic adolescents and adults tend to exhibit extensive choice switching in repeated experiential tasks. However, a recent meta-analysis showed that this switching effect was non-significant across studies. Furthermore, the relevant psychological mechanisms remain unclear.

The effect of methylphenidate and mixed amphetamine salts on cognitive reflection: a field study.

Rationale: Methylphenidate (MPH) and mixed D,L-amphetamine salts (MASs; Adderall) were previously found to have unreliable effects on judgment and decision processes.

Objective: We predicted that MPH and MASs have a specific effect of reducing heuristic responses, which should lead to increased performance on the cognitive reflection test (CRT). The CRT is considered to be a testbed for heuristic versus deliberative response modes.

Autism is not associated with poor or enhanced performance on the Iowa Gambling Task: A Meta-Analysis.

Individuals with Autism Spectrum Disorder (ASD) report difficulties in making routine decisions. Yet there is a controversy about whether their decision performance is impaired or enhanced compared to typically developing individuals. We focused on studies of the Iowa Gambling Task (IGT) where contrary arguments have been made in this regard.
