8.2 Sensitivity to envelope displacement

Figure 8.23 depicts the sensitivity measure βΔx(s) as a function of spacing. The construction of the measure and the figure is the same as described in § 5.4.3.

8.3 Sensitivity to carrier motion

Figure 8.24 measures the spacing-dependent summation of carrier motion, denoted in the model as MS for all observers who participated in the experiment. The construction is described in § 5.2.2.

Figure 8.24: Sensitivity to carrier motion as a function of spacing. This is a complete version of Figure 5.6 showing all observers; see § 5.2.2 for details on construction.


8.4 Carrier repulsion

Figure 8.25 depicts the repulsion to carrier motion MI for all observers who participated in the experiment. The construction is described in § 5.4.6.

8.5 Number and spacing

Figure 8.26 compares four model predictions for data from Experiment 2, as described in § 6.2.2.

Vertical axis measures the proportion of responding “clockwise” to a stimulus, while the horizontal axis measures inter-element spacing; colors and labels show the number of moving elements shown. See § 6.1 for details.
