Action repetition biases choice in context-dependent decision-making.

ABSTRACT: Humans are prone to decision biases, which make behavior seemingly irrational. An important cause for decision biases is that the context in which decisions are made can later influence which choices humans prefer in new situations. Current computational models (e.g. relative value learning or range normalization) often require extensive environmental knowledge to explain these biases. Here, we tested the hypothesis that decision biases are mainly driven by a tendency to repeat context-specific actions. We implemented a series of nine value-based decision-making tasks on n = 351 male and female participants and reanalyzed six previously published datasets (n = 350 participants). We found that higher within-context repetition of an option was associated with biased choices including higher
