Hand preferences on unimanual and bimanual tasks in Tonkean macaques ( Macaca tonkeana )
This is the first study to examine hand preferences in Tonkean macaques on a bimanual task. One of our objectives was to continue the move toward greater task standardization, in order to facilitate comparisons between species and studies on handedness. The main aim was to test and determine task robustness, by varying intra‐task complexity. To this end, we administered several different tasks to the subjects: two unimanual tasks (grasping task f…
Pointing gesture in young children: Hand preference and language development
This paper provides an overview of recent studies that have investigated the development of pointing behaviors in infants and toddlers. First, we focus on deictic gestures and their role in language development, taking into account the different hand shapes and the different functions of pointing, and examining the cognitive abilities that may or may not be associated with the production of pointing gestures. Second, we try to demonstrate that wh…
Features of spontaneous pointing gestures in toddlers
This study investigated the production of spontaneous pointing gestures in 26 toddlers, who were observed during free play time at day nursery. Pointing gestures and their different features (e.g., handedness, vocalizations, form and function of gesture) were recorded for a total observation time of 100 hours. Results revealed that the vast majority of pointing gestures were right-handed and accompanied by vocalizations, emphasizing the tight int…

Phylogenetic Approach to Object Manipulation in Human and Ape Infants
Object manipulation in primates is discussed with regard to the phylogenetic evolution of intelligence. Comparative data are reported on prehension schemes and levels of complexity in object manipulation by three primate species: a human infant, a pigmy chimpanzee, and a common chimpanzee. Characteristics of object manipulation in apes (e.g., exploratory mouthing without removal of objects from background) are compared with the typical manipulati…
Hand preferences on unimanual and bimanual tasks in white‐faced capuchins ( Cebus capucinus )
This study examined hand preference in white‐faced capuchins on a unimanual task and on a coordinated bimanual task. For the unimanual task, handedness was assessed by observing simple reaching for small grains. For the bimanual task, tubes lined with chocolate paste inside were presented to the capuchins. The hand and the finger(s) used to remove chocolate paste were recorded. Seven individuals out of eight in the reaching task and 12 out of 13 …
L'éthologie cognitive
Les singes s'épouillent, les araignées tissent, les lionnes chassent, les oiseaux chantent et les castors bâtissent. Les activités des animaux ont toujours beaucoup intéressé les biologistes et les psychologues. Mais l'étude des interactions de l'animal avec son milieu ne peut pas s'arrêter là : il faut aussi prendre en compte la perception que cet animal se fait des situations rencontrées ainsi que les émotions qu'il éprouve à leur sujet. Force …
Object manipulation, tool use, and the social context in human and non-human primates
Le developpement d'un comportement oriente vers des objets est compare chez trois groupes de primates : singes capucins, chimpanzes et humains, en se referant au role du contexte social dans l'acquisition de l'emploi d'outils. Une difference entre des primates humains et non-humains est le degre auquel les objets en tant que tels deviennent un centre des interactions sociales : de telles interactions par la mediation d'objets sont une particulari…
Manual laterality in nonhuman primates: A distinction between handedness and manual specialization
This article examines individual and group manual lateralization in nonhuman primates as a function of task's demands. It is suggested to distinguish low- from high-level manual activities with respect to the novelty variable and to the spatiotemporal scale of the movements. This review shows that low-level tasks lead to (a) symmetrical distributions of hand biases for the group and (b) manual preferences that are not indicative of the specializa…
