Irrelevant information should not affect our decisions. Yet, our choices are often swayed by contextual input that is entirely unrelated to the decision at hand. This is true for perceptual judgments pertaining to the appearance of a visual stimulus, as well as for more abstract evaluations of economic prospects. My doctoral work examines the context dependence of choice behavior across the realms of perception and economics. I run carefully controlled psychophysical experiments with volunteers to chart the behavioral signatures of context-dependent choices. I combine this behavioral data with simulations of mathematical models to arbitrate between different theoretical accounts of the mechanisms underlying context-dependent decision making. My work so far has encompassed decoy effects in economic decisions, distraction in perceptual decisions and categorization judgments.
