Abstract
We previously had found that left-handers who employed the inverted handwriting posture (IHP) showed no significant manual reaction time difference between homolateral and heterolateral stimulus/response-hand conditions, whereas those employing the noninverted handwriting posture (NHP) did (McKeever & Hoff, 1979). The IHP sinistrals had also shown a pattern of visual-field/response-hand-condition latencies that suggested that they might have a “disconnection” of visual and manual motor areas within the left hemisphere. The results reported here replicate the absence of a homolateral-heterolateral-conditions difference in IHP sinistrals, but not a pattern suggestive of disconnection.
