A computer touch screen system and training procedure for use with primate infants: Results from pigtail monkeys (Macaca nemestrina).

Computerized cognitive and perceptual testing has resulted in many advances towards understanding adult brain-behavior relations across a variety of abilities and species. However, there has been little migration of this technology to the assessment of very young primate subjects. We describe a training procedure and software that was developed to teach infant monkeys to interact with a touch screen computer. Eighteen infant pigtail macaques began training at 90-postnatal days and five began at 180-postnatal days. All animals were trained to reliably touch a stimulus presented on a computer screen and no significant differences were found between the two age groups. The results demonstrate the feasibility of using computers to assess cognitive and perceptual abilities early in development. (c) 2008 Wiley Periodicals, Inc.
