Gestures and different speech types in Greek speakers

The purpose of this research is to investigate the quantitative and qualitative differences in gestures produced in different types of speech and their correlation with performance on neuropsychological tests of executive functions. The research sample consists of 20 healthy volunteers who were videotaped in four different types of speech and assessed for executive functions using four neuropsychological tests. Based on McNeil's (1992) theory, two main categories of gestures were defined: referential and non-referential. The first category consists of the subtypes of iconic, metaphoric, and deictic gestures, while the second includes rhythmic and non-rhythmic gestures. Data analysis revealed differences in the mean values of the different categories of gestures, both independently and in interaction with the different types of speech. Non-referential gestures generally prevailed and were more numerous in the story of Little Red Riding Hood and the story of the birth of Christ. The subtype of gestures was found to have a major effect on the total number of gestures, with non-referential, non-rhythmic gestures outnumbering metaphoric, iconic, and deictic gestures; rhythmic gestures outnumbering deictic and iconic gestures; and metaphoric gestures outnumbering deictic and iconic gestures. Iconic gestures were also more numerous than deictic ones. The type of speech did not seem to affect the number of gestures. The total number of gestures, iconic and metaphoric gestures in the story of Little Red Riding Hood, and non-referential, rhythmic and non-rhythmic gestures in the description of the cookie theft picture negatively correlated with TMT-A, indicating a positive correlation of gestures with processing speed, visual attention, and motor coordination.
