Sammanfattning (abstract):
As gestures are known to accompany speech, they may be a possible precursor to language development (Iverson & Goldin-Meadow, 2005). Babbling has been linked to onset of rhythmic hand movements and word comprehension with emergence of deictic gestures (Bates & Dick, 2002). According to recent theories of prediction, humans need sensory feed – back in order to learn movements. Sensory feed-back and integration is impaired in autism spectrum disorders, which has consequences for the development of speech and language and manual gestures. There are substantial reasons for believing that imitation would be interconnected with theory of mind. Both aspects, imitation and theory of mind, involve translating the perspective of another individual to oneself. In the human brain, there is a neurological overlap concerning hand/arm and mouth motor function in Brocas area (Buccino, Binkofski & Riggio, 2004). We may therefore look upon Brocas area as a core area of autism spectrum disorders, as an area for speech production, mediation between production and perception, manual gestures, sensorimotor integration and theory of mind. In the current study of gestures we examine accompanying gestures in a Swedish 5-year-old boy with autism spectrum disorders who is living in a bilingual family. The boy is followed longitudinally over 1 1⁄2 years during an intervention with stimuli (minimal pairs). A corpus was collected from videofilm, transcribed and annotated for gesture data in PRAAT. The purpose is to describe gestural performance, timing and accompanying gesture types in the corpus. References Bates, E., Dick, F.
