Learning to play it safe (or not): stable and evolving neural responses during adolescent risky decision-making.

abstract：:In this paper, we describe a novel approach to the study of problem solving involving the detailed analysis of natural scanning eye movements during the "one-touch" Tower-of-London (TOL) task. We showed subjects a series of pictures depicting two arrangements of colored balls in pockets within the upper and lower halv...
