“…In other words, the results for the 1-year-olds may be a consequence of a procedure that relies on a visual response and so may have masked possible hemispheric differences in processing produced by the initial lateralization of information. The cross-modal paradigm has, however, proved sufficiently sensitive for the detection of laterality differences in adults (Gardner et al, 1977;Gardner & Ward, 1979), in 6-year-olds, children several years younger than those who showed success in Flanery and Balling's unimodal tactual study (Cioffi & Kandel, 1979;Witelson, 1976), and now in even younger children (present study).…”

“…The results demonstrate a left-hand superiority for tactile processing in children as young as 2 years. Although several studies have demonstrated a left-hand (right-hemispheric) advantage for haptic perception in adults (Cranney & Ashton, 1980;Dodds, 1978;Gardner et al, 1977;Gardner & Ward, 1979;Smith et al, 1977) the youngest age at which previous studies have found such an effect is 6 years for form perception (Cioflfi & Kandel, 1979;Witelson, 1976). Flanery and Balling (1979) questioned the appropriateness of cross-modal tasks for investigating hemispheric differences in tactual processing.…”

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

“…Most of the studies using choice-reaction time (CRT) tasks tested compatibihty by using visual and acoustic stimuli and found a clear advantage of reaction times when sahent features of stimulus and response overlapped (Proctor & Reeve, 1990) and these effects extended cross-modally (Proctor, Dutta, Kelly, & Weeks, 1994). By contrast, comparatively few studies have been conducted in the tactile modality (Leonard, 1959;Gardner & Ward, 1979;ten Hoopen, Akerboom, & Raaymakers, 1982;Hasbroucq, 1987). Ln tactuomotor stuches of compatibility, the stimulus that cues for the choice of the appropriate response is delivered in the ~ersonal rather than in the extrapersonal space.…”

We studied spatial stimulus response compatibility in the somatosensory modality by instructing 16 men and 16 women to press a key using the left or the right thumb in response to a nonnoxious electric stimulation delivered either to the left or to the right little finger or, in different blocks, to the left or to the right malleolar region. The task was performed in compatible (stimulus and key-response on the same side of the corporeal midline) and in incompatible conditions (stimulus and key-response on opposite sides of the corporeal midline). In Exp. 1 subjects were tested while keeping their limbs in anatomic position; in Exp. 2 subjects performed the task while keeping the left upper and lower limbs on the right side and the right limbs on the left side of the bodily midline (crossed position). The compatibility effect was observed in both experiments and was higher for stimuli delivered to the little finger than to the malleolar region. This suggests that the cost of inhibiting compatible responses is maximal when stimulated and responding body parts are contiguous. Moreover, in the spatially most demanding task (Exp. 2) men outperformed women for both speed and accuracy suggesting a sex related specialisation in the spatial processing of somatosensory information.
