Abstract
Current models of absolute identification emphasise different processes as the
underlying cause of observed patterns of choices and response latencies in the task.
According to one model, the Extended Generalized Context Model (EGCM; Kent &
Lamberts, 2005), behavioural latency patterns are directly linked to stimulus sampling
processes; all other models emphasise the response selection stage. In two tasks (one
using visual stimuli and one using auditory stimuli) in which stimulus exposure duration
was manipulated, we demonstrate that stimulus sampling is very rapid, but time to
respond is long. This is contrary to the EGCM predictions and implicates response
selection processes. In addition, analysis of the speed-accuracy relationship produced by
manipulations of set size, stimulus spacing and exposure duration exhibited stable
individual differences in not only magnitude, but direction. Overall, the results do not
support the emphasis on stimulus sampling in the EGCM, but do suggest downstream
influences of stimulus sampling that are neglected in other models.
