SOUZA, Rosana Machado; TUDELLA, Eloisa and TEIXEIRA, Luis Augusto. Infants' manual preference in reaching regarding spatial target location. Psicol. Reflex. Crit. [online]. 2011, vol.24, n.2, pp. 318-325. ISSN 0102-7972. http://dx.doi.org/10.1590/S0102-79722011000200013.
Manual preference of 5-month-old infants was evaluated in tasks of reaching static targets positioned on the midline, at the left and right, regarding egocentric coordinates. Frequency analysis of using the hands pointed out to diversified direction and magnitude of manual preference among infants. It was observed that they predominantly made ipsilateral reaches toward targets laterally positioned. Frequency of using the right and left hands was similar for targets located at the midline. The results suggest that in this stage of development manual preference is shifted by the spatial position of the objects.
