Peer reviewedGunderson, Virginia M.; Sackett, Gene P. – Developmental Psychology, 1984
Examined the development of pattern recognition in infant pigtailed macaques using the familiarization novelty technique. Results indicate that by at least 200 days postconception subjects show a consistently reliable visual response to novelty. (Author/RH)

Peer reviewedSackett, Gene P.; And Others – Developmental Psychology, 1976
Social and nonsocial behaviors of infant rhesus (macaca mulatta) and pigtail (M. nemestrina) monkeys reared in total social isolation were compared with those of socialized controls. Results question the generality of rhesus total isolate behavior as a model for some human problems. (Author/SB)

Peer reviewedGluck, John P.; Sackett, Gene P. – Developmental Psychology, 1976
Rhesus monkeys were reared in total isolation, in partial isolation, or under normal conditions with access to mothers and peers. Each group was compared on the rate of acquisition of a simple operant response. (GO)

Trisomy 16 in a Pigtailed Macaque ("M. nemestrina") with Multiple Anomalies and Developmental Delays
Direct linkRuppenthal, Gerald C.; Moore, Charleen M.; Best, Robert G.; Walker-Gelatt, Coleen G.; Delio, Patrick J.; Sackett, Gene P. – American Journal on Mental Retardation, 2004
A female pigtailed macaque ("Macaca nemestrina") with unusual physical characteristics, deficits in learning and cognitive tasks, abnormal social behavior, and abnormal reflexes and motor control was followed from birth until 3 years of age and found to have trisomy 16, which is homologous to trisomy 13 in humans. The animal described here showed…

Swartz, Karyl B.; Sackett, Gene P. – American Journal on Mental Retardation, 1994
Comparison of social choices of trisomic macaques and of control groups found that groups showed few differences in preferences for stimulus animals with and without disabilities. Results suggest that the avoidance of individuals with disabilities is not a general primate trait and the presence of mental retardation and physical handicaps need not…
