“…Instead, the left-hand tapping decrement of the GRGS group was not significantly different from either their own right-hand score or the left-hand score of the poor spelling groups. Similar bilaterally symmetrical interference was found in a study of White average readers (Grades 2-5) that used a modified version of the JLOT (Hiscock, Antoniuk, Prisciak, & von Hessert, 1985). The reason for this cultural difference is unclear.…”

“…Instead, the GRGS group's bilaterally equal interference observed in this study, and in that by Hiscock et al (1985), suggests that both the LH and the RH normally participate in JLOT processing. This eventuality is consistent with several studies that have attempted to determine the separate contributions of the two hemispheres in solving this task (Kim, Morrow, Passafiume, & Boller, 1984;Gur et al, 2000;Mehta & Newcombe, 1991;Mehta, Newcombe, & Damasio, 1987;Ng et al, 2000).…”

“…That is, the PRPS group consisted entirely of boys, whereas a majority of girls were present in both of the other groups. Furthermore, Hiscock et al (1985), studying good readers in Grades 2 to 5, found that boys performed more accurately than girls in a dual-task line orientation judgment experiment, and with significantly less disruption in tapping. These effects are in the opposite direction to those encountered in the present study.…”

A dual-task paradigm involving concurrent finger tapping and line orientation judgment was used to investigate brain processing differences in early adolescent good readers/poor spellers (dysgraphia), poor readers/poor spellers (dyslexia) and good readers/good spellers. Whereas all groups were similarly affected during the left-hand tapping condition, in the right-hand tapping condition the good spelling group displayed significantly less tapping disruption than both poor spelling groups, who did not differ significantly from each other. From these results, it can be inferred that individuals with dyslexia and dysgraphia share a left-hemisphere processing limitation that is not confined to written language. In light of other relevant research findings, I suggest that this limitation is due to the absence of a disembedding scanning mechanism for converting spatial arrays (e.g., spelling patterns) to temporal form-an impairment putatively caused by attempting to teach written language to children who are late in establishing left-hemisphere motor dominance.

“…Oral reading and speaking in general (Dalby, 1980;Hellige & Longstreth, 1981;Hiscock, Antoniuk, Prisciak, & von Hessert, 1985;Hiscock, Cheesman, Inch, Chipuer, & Graf, 1989;Singh, 1989) have been well established since the first experiments by Kinsbourne and Cook (1971) and Hicks (1975) as activities that interfere with the right hand more than the left. The left hemisphere typically controls speech production and distal movements of the right hand and the right hemisphere controls distal activity of the left hand.…”

“…Lateral specialization for the processing of language is detectable at an early stage in healthy children (Kinsbourne & Hiscock, 1977). Behavioral studies suggest that basic systems for language perception and control are well lateralized by approximately 3 years of age, and that the degree of lateralization is stable until adulthood (Kimura, 1967; Hiscock & Kinsbourne, 1980; Hiscock et al., 1985). Functional neuroimaging studies further support this view: Activation associated with the processing of meaningful speech is left‐hemisphere dominant, encompassing frontal and temporoparietal cortices in infants as young as 3 months of age (Dehaene‐Lambertz et al., 2002).…”

Neuropsychological and functional MRI studies provide converging evidence of anterior language dysfunction in BECTS

et al. 2009

SUMMARYPurpose: Benign childhood epilepsy with centrotemporal spikes (BECTS) is the most common epilepsy syndrome of childhood and can be associated with language difficulties. The exact profile of these difficulties and their neurofunctional underpinnings, however, are not yet clear. Methods: To further understand the impact of the BECTS syndrome on language, we assessed language performance using standard neuropsychological measures, and patterns of language lateralization using functional magnetic resonance imaging (fMRI) in children with typical BECTS (n = 20) and healthy controls (n = 20).Results: The fMRI analyses revealed that language-related activation was less lateralized to the left hemisphere in anterior brain regions in the patients relative to the control group. This finding was consistent with decreased performance in the BECTS group compared to the control group on the neuropsychological measure most dependent on the integrity of anterior aspects of the language axis, namely, sentence production. Discussion: The converging lines of evidence from the neuropsychological and activation methodologies support the view that BECTS is associated with language difficulties that are regional, and anterior, in nature.
