The role of the hippocampus in decision-making is beginning to be more understood.
Because of its prospective and inferential functions, we hypothesized that it might be …

Individuals with high trait anxiety form a non-clinical group with a predisposition for an
anxiety-related bias in emotional and cognitive processing that is considered by some to be …

Introduction Behavioral adaptation generally follows the contextual changes arising from the
consequences (rewards and punishments) of an action. According to the reciprocal …

The primary aim of this study was to compare the neural substrates of decision-making in
middle-aged children and adults. To this end, we collected fMRI data while 9–12-year-olds …

Involvement of dopamine in regulating exploration during decision-making has long been
hypothesized, but direct causal evidence in humans is still lacking. Here, we use a …

Although the cognitive theory has implicated judgment bias in various psychopathologies, its
role in decision making under risk remains relatively unexplored. In the present study, we …

Individual differences in dopamine (DA) signaling, including low striatal D2/3 receptors, may
increase vulnerability to substance abuse, although whether this phenotype confers …

Understanding the neurocognitive basis of risk-taking behavior is an important issue,
especially in economic decision-making. Classical behavioral studies have shown that risk …

Risky decisions may involve uncertainty about possible outcomes (ie, reward risk) or
uncertainty about which action should be taken (ie, behavioral risk). Determining whether …

This fMRI study investigated the neural correlates of reward-related trial-and-error learning
in association with changing degrees of stimulus–outcome predictabilities. We found that …
