Strategies for performing the task for (a) Monkey N and (b) Monkey S and for the learning phases of Monkey S: (c) before learning, (d) during learning, and (e) after learning. In each panel, reward rate (drops of juice per trial) is plotted for each stimulus onset asynchrony (SOA) as a function of proportion of correct decisions. The observed reward rate (gray circles and bold lines) is compared with other hypothetical reward rates from various strategies, given the observed distribution of correct decisions and high bets. The alternative strategies were best possible betting (black triangles), random betting (gray triangles), and worst possible betting (white triangles). For comparison, white squares show reward rates that would have occurred for perfect betting (given the monkeys’ observed distribution of correct decisions but not the observed high bets).
