Handedness and language lateralization: Neuroimaging data and implications for special education
Summary:
Handedness has been characterized as an indicator of cerebral lateralization for language, while both variables have been extensively studied in the context of special education. However, the optimal handedness measurement is still a matter of debate within the literature. Indeed, the use of certain handedeness measurements is particularly extensive in studies of language lateralization that take into account the differences between various handedness groups, yielding however few findings that indicate a clear or direct connection between handedness and cerebral lateralization for language functions. The purpose of this study is to identify a handedness measurement that could be an optimal choice in language lateralization examination research. The above scientific issue was addressed through the examination of 60 participants (M=10, W=50) with three different handedness measurements (hand preference inventory of two versions, hand preference test, hand skill test). The assessment of handedness was correlated with neuroimaging data from a word generation task under the recording of participants’ brain activity using functional transcranial Doppler ultrasound. The results revealed significant correlations between cerebral lateralization for language production and handedness for all of the three different handedness measurements. Research findings still support the use of various handedness measurements in lateralization studies. Use of optimal handedness measurements in order to assess handedness in people with disabilities and special educational needs is being discussed.
