Consider the task of selecting a medical test to determine whether a patient has a particular disease.Normatively, this requires taking into account (i) the prior probability of the disease, (ii) the likelihood|for each available test|of …

Finding the (most efficient) way out of a maze is easier than asking (good) questions

We investigate whether a spatial representation of a search task supports 4- to 7-year-old children’s information-search strategies, relative to their performance in a question-asking game. In Experiment 1, children played two computationally and …

Learning functions actively

How do people actively learn functional rules, i.e. a mapping of continuous inputs onto a continuous output? We investigate information search behavior in a multiple-feature function learning task in which participants either actively select or …
