(a) The average representational strength of the chosen picture (red), the unchosen picture (blue) or one of the unavailable options (averaged across two unavailable options; green) is shown for quick and deliberative decisions as in Figure 3, but separated by subject (Subject M: n = 272 trials, Subject N: n = 166 trials). Both subjects show similar effects. When a quick decision is made, representations of the chosen item dominate, but when subjects deliberate, chosen and unchosen representations have similar strength. (b) Chosen and unchosen representations as in a, but aligned to the time of the choice. Chosen representations do not increase in strength at the time of the choice during deliberation trials. All plots show mean ± SEM.
