Addressing Very Short Stimulus Encoding Times In Modeling Schizophrenia Cognitive Deficit, Colleen D. Cutler
Electronic Thesis and Dissertation Repository
It is well known that encoding times in persons with schizophrenia are longer than those of normal controls. Neufeld and others have argued that this is the consequence of additional subprocesses being executed during the encoding process in the case of schizophrenia. In general they expressed an encoding time as the sum of $k^{\prime}$ independent exponentially-distributed subprocesses, each executed with rate $v$. A troubling consequence of their application of this model to real data was that under some circumstances some individuals appeared to encode instantaneously. This was accommodated in Neufeld et al. by placing a Poisson distribution on …
