Fig. 4.

Amount of adaptation produced by single adapters (experiment 1) as a function of ISI or SOA (A), SOA or adapter Dur (B), and adapter Dur or ISI (C), indicated by the upper and lower abscissae in each panel. The symbols show the average across 12 participants, and the error bars show the standard error (SE). The gray lines in A and B show least-squares exponential function fits to the data (see text). The gray line in C shows a prediction of the experiment 1C data based on the function fits to the data from experiments 1A and 1B. The prediction was derived by adding to the function fit for experiment 1A the difference between the function fit for experiment 1B and the measured adaptation for the shortest (100-ms) adapter Dur (marked thin horizontal line in B). The dashed gray lines show the confidence intervals of the fitted functions (A and B) and the derived prediction (C).
