Abstract: | Eight tasks were presented to ten tufted capuchin monkeys and hand preferences were recorded for each subject on each task. The strength of hand preferences varied accross tasks. Although no significant population-level left- or right-hand bias emerged for any of the tasks, there was a tendency toward greater left-hand use in a task requiring the use of probing tools. The data also confirm that simple reaching is of limited value as a measure of hand preference. Hand preferences in capuchin monkeys appear to be determined by a number of individual, species, and environmental factors. |
