Approaches to the study of higher cognitive functions related to creativity in nonhuman animals

Fundamental to creativity is prior knowledge and learning capability. One can be creative only to the extent that one’s prior knowledge and learning abilities enable. Many of the mental functions of humans that are affected by neuropathology involve levels of learning ability that supercede those used by most animal researchers. Yet there is literature showing that there are similarities in structure and function in the cerebrum within class Mammalia and that nonhuman animals are capable of higher levels of learning than those typically studied by neuroscientists. Reviews of abstracts from the 2005 meeting of the Society for Neuroscience reveal that most neurobehavioral research with animals has involved relatively low levels of learning ability. Thomas’s [R.K. Thomas, Brain, Behav. Evol. 17 (1980) 452–474.] hierarchy of learning abilities has been revised here to better include Learning Set Formation which is fundamental to most forms of higher learning. This paper summarizes both the rationale and the methodologies that might be used to assess the roles of neuroanatomical structures involved in the psychological processes that serve as the bases of creativity.
