two sections of this chapter indicates that I have yet to practice what I preach about the analysis of dissociations. The dissociations in the operant experiments were obtained with only a few settings of the relevant experimental parameters. The results certainly demonstrate the utility of this approach to examine timing and related cognitive processes. Additional experiments are obviously necessary to determine the extent to which these dissociations are stable when confronted with parametric manipulations.
Thus, I hope I have reciprocated Endel's contributions, and left the reader wiser and more knowledgeable: Wiser about the logic that is necessary to make inferences about psychological dissociations from empirical dissociations, and more knowledgeable about the ways in which one can test cognitive processes in animals, and use neuropsychological investigations to examine the relationships between time and memory.
