Latency-probability functions as bases for evaluating competing accounts of the sensory decision process

Analyzes certain properties in 4 different models of the sensory decision process and suggests that models with those properties cannot legitimately be evaluated on the basis of differing latency-probability functions. This strategy of evaluation has been recommended and adopted in a number of studies, the only criticism having come from S. Koppell (see record 1976-29070-001), whose criticism was directed more at a particular comparison than at the strategy as a whole. The present analysis indicates that the overall strategy defaults (a) because the theoretical variables that in each model determine response probability underdetermine response latency, and (b) because there is a lack of suitably powerful measurement of those variables that affect the former but not the latter.
