Left-hand column: mean extinction indices for the control group (Panel 1A, mean; error bars represent the 95% confidence interval, CI, around the mean) and individual indices for each patient (Panels 2A and 3A), by stimulus location and modality. Right- hand column: mean probit functions for the control group (Panel 1B, mean) and individual functions for patients (Panels 2B and 3B), by stimulus onset asynchrony (SOA) and modality.

TOJ = temporal order judgment. GoF = goodness-of-fit. JND = just noticeable difference. PSS = point of subjective simultane- ity. CI = confidence interval. JND, PSS, and 95% CI for PSS are reported in ms. p-values associated with the GoF statistics indicate the probability that the difference between the observed data and estimated functions is statistically significant. In the right-hand column the p-values indicate the probability that the PSS estimate is equal to zero (PSS = 0). tasks (see Figure 3, Panel 1A), demonstrating consistent performance between single- and dual-target trials. Results for the TOJ task also demonstrated near veridical judgments of temporal asynchrony. Panel 1B in Figure 3 plots the mean probit function as a function of SOA for the visual and auditory stimuli. For comparison with the patients, the mean PSS values for the control group along with the 95% confidence intervals (CIs) are presented in Table 3. In the visual modality, the mean PSS was –13 ms (SD = 26 ms), and in the auditory modality it was 15 ms (SD = 44 ms). Neither PSS dif- fered significantly from zero, t(14) = –1.97, p = .07, and
