“…Their results confirmed those of Benton et al (1962) that self-reports of 1eft handers were not predictive of manual proficiency. Whereas performance of self-c1assified right handers on manua1 tests corre1ated high1y with their verbal reports of hand preference, se1f-c1assified 1eft handers varied in both manua1 and speech 1atera1ity.…”

“…Benton, Meyers & Polder (1962) showed that self-reports on hand preference were significantly correlated with manual dexterity in righthanded, but not in left-handed individuals. Barnsley & Rabinovitch (1970) further pointed out that the full range of skills involved in hand performance should be taken into account.…”

Ear asymmetry for dichotic digits was used to indicate speech latera1ity in 19 hearing-impaired and 19 normal-hearing children. Sequences of 2, 4 and 6 digits were also presented monaura11y. Whereas for the norma1-hearing group right-ear dichotic scores were significant1y superior, inter-subject variabi1ity resu1ted in a non- The groups did not differ significant1y in relative right1eft hand proficiency. No correlation was found between hand and ear latera1ity in either group, nor between degree of ear asymmetry and vocabu1ary scores for hearing-impaired subjects. Discrimination of a dichotic pair by the latter subjects rarely occurred, with one digit apparently masking or suppressing the other. Prediction of speech lateralization in hea~ing-impaired children from dichotic digit scores was not reccmmended.

“…Early studies by Benton [3] revealed that while 60% of righthanders with left hemisphere lesions presented with language impairments, only 32% of left-handers did. Hecaen and Sauget [32] report that though left-handers with left hemisphere lesions typically experience similar production difficulties as do right-handers, they are less likely to present with comprehension deficits.…”

To address the impact of differences in language lateralization on joke comprehension, event-related brain potentials (ERPs) were recorded as 16 left-and 16 right-handed adults read one-line jokes and non-funny control stimuli (''A replacement player hit a home run with my girl/ball,''). In right-handers, jokes elicited a late positivity 500 -900 ms post-stimulus onset that was largest over right hemisphere (RH) centro-parietal electrode sites, and a slow sustained negativity over anterior left lateral sites. In left-handers, jokes elicited a late positivity 500 -900 ms post-onset that was larger and more broadly distributed than in the right-handers' ERPs. In right-handed women, the late positivity was larger over RH electrode sites. In left-handed women, the late positivity was bilaterally symmetric. The highly asymmetric slow sustained negativity over left anterior electrode sites was absent from left-handers' ERPs to jokes. Differences may reflect more efficient inter-hemispheric communication in the left-handers, as they are reputed to have relatively larger corpus callosal areas than right-handers. Results support the portrait of more bilateral language representation among left-handers, and suggest language lateralization affects highlevel language comprehension tasks such as joke comprehension.

“…The problems involved in the measurement of handedness have been comprehensively discussed (Benton, Meyers and Polder, 1962), but the relationship between hand preference (determined by self-report and response to questionnaire) and manual dexterity (measured by motor tasks) is far from clear (compare Satz, Achenbach and Fennell, 1967;Annett, 1970 a;Provins and Cunliffe, 1972). All our observations are concerned with reported preference and not measured performance; and for the reasons which Oldfield (1971) has enumerated we chose the questionnaire method of assessing hand preference for the Otmoor sample.…”

Hand preference and I.Q. in a group of Oxfordshire villages

Verbal and performance scores in a standard intelligence test (WAIS) were considered in relation to patterns of hand preference (measured by questionnaire) in a large sample of the general population. Left-handers and mixed-handers did not obtain lower scores than right-handers. Indeed, there was a tendency for subjects who reported that they could use either hand for at least one of the questionnaire tasks to obtain higher I.Q.s. Otherwise, there were no significant differences in I.Q. with the exception of a consistent sex difference, in that men achieved higher scores on both verbal and performance scales.
