Individual Response Strategies in List Learning by Orangutans

Two orangutans learned eight lists of items in a recognition memory procedure that allowed the list items to be reported in any order. In a previous study using this same procedure, the orangutans developed a spatial response strategy that was applied to acquisition of novel lists. The purpose of the present study was to determine […]

Response strategies inlist learning by orangutans (Pongo pygmaeus × P. abelii)

Rhesus monkeys (Macaca mulatta) develop strategies to acquire and execute serial lists (K. B. Swartz & S. A. Himmanen, 2001). Serial probe recognition studies of list memory have demonstrated similarities across monkeys and humans (S. F. Sands & A. A. Wright, 1980). The present study extended the investigation of list learning and memory to determine […]
