Time-resolved proportion of choice for chocolate as a function of trial number A) Time-resolved proportion of chocolate choice was modelled from trial 11 to 35, integrated over choices in the last 10 preceding trials.

<p>Mean choice proportion estimates with bootstrapped 95% confidence intervals for the conditions with expensive chocolate are displayed for the 5:3 (uncompensated, blue line) and 5:3C (compensated, red dashed line) conditions. Purple bar: Difference in Z-value > 1.96 (p<0.05, Bonferroni-corrected for multiple comparisons to |Z|>3.07). B) as in A), but now for choice proportions estimated for the conditions with inexpensive chocolate (3:5, uncompensated, blue line; 3:5C, compensated, red dashed line).
