Abstract:
Monkeys show an innate ability at problem solving. This can be seen across many species, New World and Old World. This study focuses on five different monkeys and their ability to manipulate and solve six different latches to access a novel food item. Three guenon species and two capuchin species were tested three times with a thirty-minute trial run. Each species, age group, and monkey group displayed different abilities of completing the enrichment. ( , )

FACTORS INFLUENCING VARIATIONS IN MONKEY PROBLEMSOLVINGAbigail Cotner

PAGE 2

INTRODUCTION & BACKGROUND•Explore the capabilities of multiple species and their comprehensive understanding of complex tasks • Enriching their day to day lives with a new opportunity • Results of this research will provide insight into the diversity of primate cognition and provide stimulating enrichment

PAGE 3

HYPOTHESES OF INTEREST•Each capuchin species has a different problem solving ability Sapajus apella and C ebus capuchins. • The guenon monkeys will each display a different capacity at solving complex tasks Cercopithecus ascanius, Cercopithecus neglectus, and Cercopithecus wolfi. • New world monkeys and Old World monkeys have different problem solving abilities. • There will be a difference between the abilities of younger individuals compared to older individuals in their problem solving skills.

METHODS•Place novel food items inside boxes • Shift monkeys to opposite side of cage • Attach box to interior of cage • Give monkeys access to both sides • Video and observe behaviors for 30 mins, repeat for another 2 trials • T tests and ANOVA tests 1 II III IV V VI

DISCUSSION•Adults may be better problem solvers • Juveniles are more curious • Old World Monkeys are better problem solvers • Brain size does not necessarily mean more capable • There is no difference in capuchin species capabilities

PAGE 13

CONCLUSION•Future studies should look into separating individuals and testing age capabilities and/or sex • Also control the time at which the monkeys are fed before the test • Further do not give monkeys any other form of enrichment • Novel food item should be something they all can eat
