SOUZA, Rosana Machado de  and  TEIXEIRA, Luis Augusto. The relationship between phylogeny and ontogeny in the development of infant laterality. Psicol. Reflex. Crit. [online]. 2011, vol.24, n.1, pp.62-70. ISSN 0102-7972.

Human laterality has been conceived as resulting, predominantly, from phylogenetic factors in human development, whereas individual-environment interaction is thought to play only a minor role. This study aims at presenting a critical review of literature showing evidence of the effect of phylogenetic and ontogenetic factors on the development of laterality, with particular emphasis on the first years of life. From the results presented, we propose that human laterality is a dynamic process, with sharp effects of lateralized sensorimotor experiences over manual preference and interlateral asymmetry of motor performance.
