Meaning in Words, Gestures, and Mental Images

چکیده
In this study, we provide evidence for a cross-modal interaction between the meaning of pantomimes and words when the visuo-spatial and perceptual information of these last is enhanced. We recorded behavioral and electrophysiological responses with a cross-modal repetition priming. Pantomimes of objects and actions were used to prime visually presented nouns and verbs with an image formation task. The behavioral results showed that the image formation times of words primed by a preceding gesture were faster in the matching meaning condition than in the mismatching one. Electrophysiological results confirmed the interaction between gesture and word meanings showing a N400 localized all over the scalp with a peak on the left anterior hemisphere. Overall, these results support the idea of a tight interplay between the meaning of pantomimes and words when perceptual information is enhanced in words at both the behavioral and neurophysiological levels.

Mental Timeline in Persian Speakers’ Co-speech Gestures based on Lakoff and Johnson’s Conceptual Metaphor Theory
One of the introduced conceptual metaphors is the metaphor of "time as space". Time as an abstract concept is conceptualized by a concrete concept like space. This conceptualization of time is also reflected in co-speech gestures. In this research, we try to find out what dimension and direction the mental timeline has in co-speech gestures and under the influence of which one of the metaphoric...

متن کاملIconic gestures prime words: comparison of priming effects when gestures are presented alone and when they are accompanying speech
Previous studies have shown that iconic gestures presented in an isolated manner prime visually presented semantically related words. Since gestures and speech are almost always produced together, this study examined whether iconic gestures accompanying speech would prime words and compared the priming effect of iconic gestures with speech to that of iconic gestures presented alone. Adult parti...

Sound has been an overlooked modality in visualization. Why? Because it is ephemeral. We experience it as it happens, often in community with others. Then, the sound is gone. Furthermore, sound in human communication is multidimensional and includes the semantic meaning of words, the meaning of expressive verbal gestures (paralingual and prosodic components), the nonvocal gestures, and relation...
