“…The apparent increase in the degree of lateralized hand use which all animals showed when adopting a bipedal posture (Tasks B, C, and D) compared to a quadrupedal posture (Task A) is in line with reports from several other primate species (ANDERSON et al, 1996;DEVLEESCHOUWER et al, 1995;DIAMOND & MCGREW, 1994;HOPKINS, 1993) and illustrates that measurement of simple food reaching from the floor alone may give a rather incomplete picture of functional forelimb laterality in a primate species.…”

ABSTRACT. The purpose of this study was to test the influence of sex, age, social rank, matriline membership, posture, and visual and tactual motor control on manual preferences in Saimiri sciureus. A well-established social group of 12 squirrel monkeys, aged 2 to 14 yrs and consisting of two matrilines with social rank known for each animal, was presented with four different foodreaching tasks and assessed for hand preferences with a minimum of 100 reaches per animal.Frequency of occurrence of hand preferences at the group level and degree of hand preferences at the individual level depended on posture and on whether the reaching act took place under visual or tactual guidance. Sex, age, social rank, and matriline membership were not found to determine frequency of occurrence, direction or degree of hand preferences with the exception of one task in which a significant negative correlation between the degree of hand preference and age was found. Nine out of 12 monkeys showed task-dependent changes in the hand they used preferentially while only three animals preferred the same hand in all four tasks. Significant preferences for the use of right or left hand on a given task were distributed almost equally between individuals. Thus, the results of this study suggest task-specific demands like posture and/or whether reaching was visually or taetually guided to be the major correlates of hand preferences in food-reaching tasks in squirrel monkeys.

“…Studies across several primate taxa provide support for the notion that more complex tasks elicit a greater consistency and strength of hand preference than do more simple tasks such as reaching (Cebus: Anderson, Degiorgio, Lamarque, & Fagot, 1996;Spinozzi et al, 1998;Cercocebus: Blois-Heulin, Guitton, Nedellec, Bienvenue, Ropars, & Vallet, 2006;Pan: Hopkins & Rabinowitz, 1997;Papio: Vauclair et al, 2005). The TUBE task (Hopkins, 1995) is one measure of complex bimanual coordination that has been tested in several primate species, including chimpanzees and capuchins.…”

A comparative study of chimpanzee (Pan troglodytes) and capuchin monkey (Cebus apella) cerebellar asymmetry and its relationship to handedness was conducted. Magnetic resonance images of the brain and behavioral data on a coordinated bimanual task were obtained from 16 chimpanzees and 11 capuchins. Chimpanzees displayed a greater rightward bias of the posterior cerebellum and capuchins displayed a greater leftward bias of the anterior cerebellum. Cerebellar asymmetries were significantly associated with handedness in capuchins but not chimpanzees, and this effect was most pronounced in right-handed capuchins.

“…Given the association between tool use, finer motor control and the leading role of the left hemisphere for highly demanding processes [Fagot and Vauclair, 1991;Hammond, 2002;IturriaMedina et al, 2011], right-handedness could be expected. Although there are some studies that show a left-hand bias during tool use in non-human primates [Westergaard, 1991;McGrew and Marchant, 1992;Anderson, 1996;Bogart et al, 2012;Phillips and Thompson, 2013], they focused on tool use involving probing, which probably requires more tactile input. The left-hand preference could reflect asymmetry favouring the right cerebral hemisphere for its haptic sensory inputting [Cochet and Byrne, 2013;Phillips and Thompson, 2013].…”

Hand Preference during Tool Use in Wild Bearded Capuchins

The preferential use of one limb (lateralization) has been observed in many species. This lateralization reflects functional asymmetries of the brain. Right-handedness and left-hemisphere dominance seem to be the norm in humans. However, suggestions that vertebrates, particularly non-human primates, show handedness are contentious. Tool use could be a driver of handedness. Here I investigated hand bias during tool use activities in groups of wild capuchins (Sapajus libidinosus). I observed the use of feeding tools in wild capuchin monkeys living in the dry Caatinga forests of the Serra da Capivara National Park, Piaui, Brazil. Capuchins used three major types of feeding tools: (a) tools for probing; (b) tools for pounding/cracking, and (c) digging stones to extract tubers or roots. I recorded hand use in 118 tool use bouts. These different types of tools had different motor demands; digging tools apparently favour right-hand use. The harsh Caatinga habitat poses a strong selective pressure for tool using, which might favour increased laterality and right-hand bias. However, the extent of right-handedness associated with tool use, particularly for digging, can only be fully evaluated following studies with larger sample sizes.
