Résumé / Abstract

The development of prehension was studied in babies aged between 6 and 20 months in a partial replication of the classic study by Halverson (1931). In our study the objects to be grasped were spheres and cubes carefully graded to allow comparisons of grips with object shape and size controlled. The trend noted by Halverson, for power grips to decrease and precision grips to increase, was replicated so that by the second year precision grasping is the dominant mode of prehension. However, the transition to precision grasping appears to occur by selection from a developmentally prior mixture of power and precision grips. In comparing spheres and cubes object size was the most important factor influencing grip selection but object shape also had a lesser influence. Object size may have acted as a scaling factor for grip selection. The findings are discussed in relation to a selectionist approach to the development of prehension.
