The interactive functional biases of manual, language and attention systems.

ABSTRACT: Hemispheric lateralisation is a fundamental principle of functional brain organisation. We studied two core cognitive functions-language and visuospatial attention-that typically lateralise in opposite cerebral hemispheres. In this work, we tested both left- and right-handed participants on lexical decision-making as well as on symmetry detection by means of a visual half-field paradigm with various target-distractor combinations simultaneously presented to opposite visual fields. Laterality indexes were analysed using a behavioural metrics in single individuals as well as between individuals. We observed that lateralisation of language and visuospatial attention as well as their relationship generally followed a left-right profile, albeit with differences as a function of handedness and t
