Hand position during writing, cerebral laterality and reading: Age and sex differences

Levy and Reid's neurological model in relation to writing hand/posture: An evaluation.

“…They have also reported significantly higher proportions of male than female sinistrals using the inverted posture. Such sex differences have also been reported by the smaller studies of Allen and Wellman (1980), Herron et al (1979), and McKeever and Van-Deventer (1980). Applying Levy and Reid's (1976) In addition to the tendency for these estimates of inversion to be lower when the proportion of females in the sample increased, the estimates also appeared to reflect the posture classification procedures of the three studies.…”

“…Such conformity is possibly greater among females (McKeever & VanDeventer, 1980). The findings of Allen and Wellman (1980) and of Coren and Porac (1979) that the incidence of inversion decreases with increasing age, and the contrasting finding of Peters and Pedersen (1978) that such incidence increases with age, are not directly compatible with a genetic-based theory of hand/posture.…”

“…Herron et al stressed the importance of not treating language as a unitary function. That reading is in some way related to writing hand/posture was also supported by Allen and Wellman's (1980) finding that among elementary school children, the closer writing posture was to the normal position, the better the child's reading ability. However, evidence for the existence of a relation between hand/posture and visual language is at best equivocal, inasmuch as such a claim is contradicted by the findings of Bradshaw et al (Note 1), Bradshaw and Taylor (1979), McKeever (1979), McKeever and VanDeventer (1980), and Weber (1980.…”

Hemispheric Dominance: Its Development and Relation to Speech Disorders

“…Dcxtrals with a normal writing posi tion and sinistrals with a hooked or inverted posture had verbally specialized left hemi spheres and spatially specialized right hemi spheres. Sinistrals with a normal writing po sition and dextrals with an inverted position manifested the reverse [Levy and Reid, 1977], Subsequent studies, however, could not confirm this [McKeever and Van De venter, 1980], Inverted hand position seems to be also correlated with decreased reading ability in children [Allen and Wellman, 1980], In addition to handedness, eye, ear and foot preferences have been studied. Sighting dominance for the right eye is more preva lent, but it is not correlated well with other hemispheric asymmetries.…”

Relación entre habilidades neuropsicológicas y comprensión lectora en Educación Primaria

“…En el caso de que, por ejemplo, utilizara la mano, el oído y el pie del lado derecho pero el ojo dominante fuera el izquierdo, se puede decir que es una lateralidad no homogénea. En algunos estudios realizados en épocas anteriores como el de Longoni, Scalisi y Grilli (1989) no se hallaron diferencias significativas en cuanto al rendimiento de la lectura en niños con lateralidad cruzada, mientras que en otros trabajos hay evidencias de que la lateralidad se relaciona con la lectura (e.g., Allen y Wellman, 1980). De la misma manera, estudios más actuales también muestran que la lateralidad se relaciona con el aprendizaje y dominio de la competencia en la lectura.…”
