Abstract When adapting to a risky world, decision makers must be capable of grasping the probabilistic nature of the environment. Developmental research on the ontogeny of the ability to use probabilities thus far has used different paradigms and revealed inconsistent findings. Merging two paradigms (choices based on probabilistic inferences; trust-in-informants decisions), we tested whether procedural differences are responsible for the inconsistent findings. 6-, 9-, and 22-year-olds (N = 108) ...

Abstract Not all information is equally relevant for making good choices. Do children find it difficult to use information weights for an adaptive information search because of their insensitivity towards search costs? To address this question, we used an information-board game played either with or without search costs to compare decisions of 8- to 10-year-olds, 11- to 12-year-olds, and young adults. To assess the use of weights, we manipulated the weight-structure (high vs. low weight dispersi...

ABSTRACTIn many decision situations, individuals must actively search information before they can make a satisfying choice. In such instances, individuals must be aware of the fact that not all information may be equally relevant for the choice at hand—thus, individuals should weight information by its respective relevance. We compared children’s and adult’s decision-making in a child-friendly decision game. For each decision, participants received information on the content of 3 piggy banks on ...

We investigated whether children prefer feedback over stated probabilistic information in decision making. 6-year-olds’, 9-year-olds’, and adults’ decision making was examined in an environment where probabilistic information about choice outcome had to be actively searched (N = 166) or was available without search (N = 183). Probabilistic information was given before choices as predictions of cues differing in validity. The presence of outcome feedback was varied. Six-year-olds, but not nine-ye...

Adaptive actors must be able to use probabilities as decision weights. In a computerized multi-attribute task, the authors examined the decisions of children (5--6 years, n = 44; 9--10 y., n = 39) and adults (21--22 y., n = 31) in an environment that fosters the application of a weighted-additive strategy that uses probabilities as weights (WADD: choose option with highest sum of probability-value products). Applying a Bayesian outcome-based strategy classification procedure from adult research,...

Weighted-additive (WADD) strategies require decision makers to integrate multiple values weighted by their relevance. From what age can children make choices in line with such a WADD-strategy? We compare multi-attribute decisions of children (6–7; 8–10; 11–12-year-olds) with adults in an open information-board environment without pre-decisional information search. In two experiments, we classify decision strategies based on individual choice patterns and find that in all age groups the majority ...

Abstract To make decisions in probabilistic inference tasks, individuals integrate relevant information partly in an automatic manner. Thereby, potentially irrelevant stimuli that are additionally presented can intrude on the decision process (e.g., Sollner, Broder, Glockner, & Betsch, 2014). We investigate whether such an intrusion effect can also be caused by potentially irrelevant or even misleading knowledge activated from memory. In four studies that combine a standard information board par...

This paper presents an experimental study investigating the interplay of individuals’ other-regarding preferences and individuals’ risk attitude. Participants (N=120) had to make choices between a certain and risky payoff only for themselves (individual context) and choices in which the participants were paired with another randomly assigned participant who functioned as a passive recipient (interpersonal context). In the interpersonal context the risky option was beneficial for the other person...

Adaptive decision making in probabilistic environments requires individuals to use probabilities as weights in predecisional information searches and/or when making subsequent choices. Within a child-friendly computerized environment (Mousekids), we tracked 205 children's (105 children 5-6 years of age and 100 children 9-10 years of age) and 103 adults' (age range: 21-22 years) search behaviors and decisions under different probability dispersions (.17;.33,.83 vs. .50,.67,.83) and constraint con...
