| summary | Limb apraxia is an acquired deficit in processing hand gestures, whereas limb dyspraxia refers to a delay in the development of gestural abilities. Praxis deficits can be detected through the assessment of different gesture types (ie, meaningful and meaningless) carried out in different modalities (ie, elicited by a verbal or visual command or by imitation). Recent cognitive models of praxis processing (Rothi et al. 1991; Cubelli et al. 2000) have been developed to account for the complexity of limb apraxia. Based on these cognitive models, we devised and administered a
battery of tasks for the assessment of praxis abilities to a group of left-brain damaged patients and to individuals with autism. Results showed dissociations among gestures, suggesting that each gesture calls for specific cognitive skills.
