Comparison of cognitive function in human and non-human primates.
Fundamental to any comparative study of cognitive function in monkey and man is the demonstration of behavioral homology, viz. that the same cognitive function is being studied in both species. This paper considers a variety of psychological issues that need to be taken into account when attempting to demonstrate behavioural homology. Examples are taken from studies of attentional set-shifting, discrimination reversal learning, spatial working memory and episodic memory. Whilst highlighting the pitfalls to be avoided in the future, these examples also demonstrate the enormous contribution that such studies have had to our understanding of the functions of the temporal lobes and frontal lobes. Moreover, they also illustrate the enormous potential in defining the cognitive functions and dysfunctions of the prefronto-striatal circuitry which underlie so many neurodegenerative and neuropsychiatric disorders.
