Figure 3.

Figure 3

Mean difference between the log threshold contrast values for the asynchronous and synchronous conditions of Fig. 2 as a function of log target duration for the four observers for either static noise (filled squares) or dynamic noise (unfilled squares). Error bars indicate ±1 SEM. Curves represent the differences between the corresponding fitted functions of Fig. 2. The horizontal dashed line indicates equality between the log threshold contrast values for the asynchronous and synchronous conditions. Target durations in ms are indicated on the top x-axis.
