“…In that 6-month-old infants used their two hands equally often in making contact with an object whereas 8-month old infants used their right hand twice as often as their left, these data indicate age-related changes in the development of right hand usage. This is consistent with the general direction of findings reported by Cohen (1966) and Ramsay (1980). Cohen (1966) found that 8-month old infants exhibited a significant right-handed preference in reaching.…”

To examine age-related changes in hemispheric specialization, 6-and 8-monthold infants were presented with auditory input while reaching for an object. Music or speech were presented separately to the infants' right or left ears. Examination of the latency to contact the object revealed a complex relationship between type of auditory input and locus of presentation as a function of age and gender. In younger boys presentation of speech to the left ear resulted in longer contact latencies than did presentation of music. Younger girls showed no asymmetries. Older boys took significantly longer to contact when music was presented to their right than to their left ear; older girls exhibited a tendency toward the typical adult pattern of specialization in that there was a greater effect of speech at their right than at their left ear and vice versa for music. These data are discussed in terms of possible sequences in the development of hemispheric specialization.

“…However, a determination of handedness has been considered problemmatic in children as young as these used in present study. Some investigators have suggested that dominant hand usage actually undergoes cyclical changes during infancy (Cohen, 1966;Gesell & Ames, 1947), with consistent usage emerging at age 3 (Ingram, 1975) and then increasing at least until age 10 (Miller, 1982) Nonetheless, the fact that some forms of consistent nght-hand usage seem to emerge as early as the second half of the first year of life (Ramsay, 1980) suggests that it may be possible to distinguish righthanded children at an earlier age than previously thought possible In any event, it is possible to determine current hand preference and usage.…”

This experiment was conducted to determine whether young children show any evidence of right hemispheric specialization for tactual processing. Seventy-two 1-, 2-, and 3-year-old right-handed children were each administered six cross-modal tasks in which they palpated a shape with either their left or right hand for 25 s and then viewed the familiar and a novel shape in a 10-s test of visual recognition. Although children of all three ages showed significantly more visual fixation to novel shapes, regardless of which hand had been used for palpation, scores were enhanced among 2-and 3-year-olds following palpation with the left as compared with the right hand. This left-hand (right hemisphere) superiority was not evident in 1-year-olds. These results are the first to demonstrate a left-hand superiority for information processing in children as young as 2 years and to suggest that this adult-like pattern is developed by at least the second year of life.There is now ample evidence that the right and left hemispheres of the human brain differ anatomically and functionally in adults, with language and analytical sequential processing lateralized in the left hemisphere and visuospatial and nonsequential processes lateralized in the right hemisphere (e.g., Gazzaniga, 1970;Sperry, 1982). Fundamental questions remain, however, as to how and when these basic differences between the left and right brain emerge. Lennenberg's (1967) review of the literature available in the 1960s led him to conclude that lateralization of function develops over time and is not complete until puberty. However, recent evidence suggests that certain anatomical, electrophysiological, and motor

“…Early acquisition of hand‐use preferences has been proposed to facilitate cognitive, motor, and emotional development in infancy (e.g., Cohen, ; Hildreth, ). Also, a stable hand preference was shown to be associated with more effective object management skills involving the “storage” of objects (“retaining control of an object by transferring it to another hand or placing, without haphazardly dropping, an object within reach”; Kotwica, Ferre, & Michel, , p. 519).…”

This is the first paper in a series of three discussing different aspects of the development of role-differentiated bimanual manipulation (RDBM-two hands performing different but complementary actions on an object). Emergence of RDBM is an important shift in the development of infant manual skills. Trajectories of monthly changes in the number of RDBMs and RDBM hand preference were explored in a sample of 90 (57 males) normally developing infants (30 with a right preference for acquiring objects, 30 with a left preference, 30 with no preference) during the 9-14 month period. Multilevel analysis revealed that infants performed more RDBMs with age, with similar patterns of change in all hand preference groups. A hand-use preference for RDBM became more prominent with age with most right-preferring infants and those without a preference for object acquisition developing right-hand preference for RDBM. Left-preferring infants exhibited more heterogeneity in their hand-use for RDBM.
