Table 5.

Means (first lines) and standard deviations (second lines) are shown for parameters from each experiment for the LCA model. a is the height of the response boundary above zero, s is the standard deviation of the Gaussian internal processing noise, T_er is the mean non-decision time, s_z is the range [0, s_z] of uniformly distributed across-trial variability of the starting point, s_t is the range of the across-trial variability in non-decision time, and p is the exponent in the psychophysical power-law transformation function.
