Illusory correlation and cognitive processes: a multinomial model of source-monitoring

The present research examines how the application of a multinomial source-monitoring model in the illusory correlation paradigm (Klauer & Meiser, 2000) can shed light on the cognitive processes underlying illusory correlation paradigm in children. A source-monitoring analysis allows assessing the roles of different factors (item memory, source memory and response bias) involved in the illusory correlation. In line with the previous source-monitoring analyses on adults (Klauer & Meiser, 2000; Meiser & Hewstone, 2001), illusory correlation phenomenon was caused by the guessing bias in source discrimination: a larger proportion of positive than negative behaviors was attributed to the majority group in a state of memory uncertainty. The results are discussed in terms of previously proposed theories of illusory correlation paradigm

The role of probabilistic reasoning abilities on adolescent risk taking

The aim of this work was to investigate the role of the cognitive system and the affective system on adolescents’ risk taking in gambling tasks characterized as different on the basis of information given to decision makers. In Study 1, we explored the role of probabilistic reasoning and sensation seeking on decision making in a non-risky context (Non-Gambling Task) and a risky context (Gambling Task) in which no preliminary information were given to participants. Results showed that adolescents referred to probabilistic reasoning only in the Non-Gambling Task. In Study 2, we explored the role of probabilistic reasoning and sensation seeking in risky situations with preliminary information given to participants. Specifically, we compared a risky context characterized by high-emotional arousal (Game of Dice Task), in which a feedback after each decision was given, with one characterized by low-emotional arousal (Game of Dice Task – Modified version), without feedback. Probabilistic reasoning characterized adolescents’ decision making regardless of feedback. Findings showed that adolescents’ decision making was solely linked to the cognitive system in the non-risky situation, and the affective system overcomes the cognitive system in situation of risk. Moreover, providing information about the task might interfere with the imbalance between the two systems
