Table 1. experimental and computational-model derived variables.

The table summarizes for both tasks their experimental and model-derived dependent variables. DATA: experimental data; RELATIVE: relative value learning model with delta rule update and context-specific heuristic (best fitting model); ABSOLUTE: absolute value learning model. Data are expressed as mean ± s.e.m.
