Humans often have an intuitive sense of whether they made the right decision or not -- our sense of confidence. In studies on metacognitive faculties, confidence is most often assessed explicitly, by asking participants how confident they are in their response being correct. While we can explicitly report our confidence, implicit methods of…

Delay discounting tasks measure the relation between reinforcer delay and efficacy. The present study established the association between delay discounting and classroom behavior and introduced a brief measure quantifying sensitivity to reward delays for school-aged children. Study 1 reanalyzed data collected by Reed and Martens (J Appl Behav Anal…

Adults deliver mixed messages to children about the acceptability of truth- and lie-telling across contexts. To probe this discrepancy, we investigated how adults evaluate children's truths and lies across various situations. Participants watched videos of children telling prosocial lies or hurtful truths that varied in their directness (blunt or…

When making decisions, the amount of time remaining matters. When time horizons are long, exploring unknown options can inform later decisions, but when time horizons are short, exploiting known options should be prioritized. While adults and adolescents adapt their exploration in this way, it is unclear when such adaptation emerges and how…

Most experimental preparations demonstrate a role for dorsolateral striatum (DLS) in stimulus-response, but not outcome-based, learning. Here, we assessed DLS involvement in a touchscreen-based reversal task requiring mice to update choice following a change in stimulus-reward contingencies. In vivo single-unit recordings in the DLS showed…

Theories of perceptual decision making have been dominated by the idea that evidence accumulates in favor of different alternatives until some fixed threshold amount is reached, which triggers a decision. Recent theories have suggested that these thresholds may not be fixed during each decision but change as time passes. These collapsing…

Children have a powerful ability to track probabilistic information, but there are also situations in which young learners simply follow what another person says or does at the cost of obtaining rewards. This latter phenomenon, sometimes termed bias to trust in testimony, has primarily been studied in children preschool-age and younger, presumably…

The purpose of this study was to examine kindergarten children's motivation choice after successfully completing a mathematical task. Three succeeding measurements took place in two-week intervals. In each measurement a different choice dyad was presented to participating children. After the successful completion of a mathematical activity,…

Long-term fear memory formation in the hippocampus and neocortex depends upon brain-derived neurotrophic factor (BDNF) signaling after acquisition. Incremental, appetitive odor discrimination learning is thought to depend substantially on the differentiation of adult-born neurons within the olfactory bulb (OB)--a process that is closely associated…

Many researchers have used the standard Iowa Gambling Task (IGT) to assess decision-making in adolescence given increased risk-taking during this developmental period. Most studies are cross-sectional and do not observe behavioral trajectories over time, limiting interpretation. This longitudinal study investigated healthy adolescents' and young…

Balancing habitual and deliberate forms of choice entails a comparison of their respective merits--the former being faster but inflexible, and the latter slower but more versatile. Here, we show that arbitration between these two forms of control can be derived from first principles within an Active Inference scheme. We illustrate our arguments…

Children are notoriously bad at delaying gratification to achieve later, greater rewards (e.g., Piaget, 1970)--and some are worse at waiting than others. Individual differences in the ability-to-wait have been attributed to self-control, in part because of evidence that long-delayers are more successful in later life (e.g., Shoda, Mischel, &…

We examined the role of working memory (WM) in dynamic decision making by having participants perform decision-making tasks under single-task or dual-task conditions. In 2 experiments participants performed dynamic decision-making tasks in which they chose 1 of 2 options on each trial. The decreasing option always gave a larger immediate reward…

Children's epistemic vigilance was examined for their reasoning about the intentions and outcomes of informants' past testimony. In a 2 x 2 factorial design, 5- and 6-year-olds witnessed informants offering advice based on the intent to help or deceive others about the location of hidden prizes, with the advice leading to positive or negative…

Individuals with depressive symptoms typically show deficits in decision-making. However, most work has emphasized decision-making under gain-maximization conditions. A gain-maximization framework may undermine decision-making when depressive symptoms are present because depressives are generally more sensitive to losses than gains. The present…
