    A study of using metaphoric and beat gestures with motion-based and non-motion-based metaphors during retelling stories
    (MDPI, 2022-04) Khatin-Zadeh, Omid; Farsani, Danyal; Reali, Florencia
    In this paper, we classify metaphors into four categories: motion-based metaphors, static space-based metaphors, static object-based metaphors, and static event-based metaphors. Then, a study that investigated the use of gestures with these types of metaphors is reported. The aim was to examine how these types of metaphors are used with metaphoric and beat gestures during the process of re-telling stories. The participants of the study listened to three audio stories. Each story contained two motion-based metaphors, two static space-based metaphors, two static object-based metaphors, and two static event-based metaphors. After listening to each story, they had to retell the stories in front of a camera. The videos were analyzed to determine the number of metaphoric gestures and beat gestures that had been used by participants during the retelling of the stories. The results showed that the highest number of metaphoric gestures had been used with static space based metaphors. This was followed by motion-based metaphors, static object-based metaphors, and static event-based metaphors, respectively. On the other hand, the highest number of beat gestures was used with static event-based metaphors. These findings indicate that the use of metaphoric gestures and beat gestures accompanying metaphors is highly dependent on the spatial and motoric properties of the base of the metaphors, which supports the idea of embodied metaphor comprehension.

    The impact of gestural representation of metaphor schema on metaphor comprehension
    (De Gruyter Mouton, 2023) Khatin-Zadeh, Omid; Hu, Jiehui; Marmolejo-Ramos, Fernando; Farsani, Danyal
    This study aimed to investigate how priming a metaphor by the gestural representation of its schema affects the understanding of that metaphor. In each of the two tests, different groups of participants were invited to judge the sensibility of the same 20 metaphors preceded by congruent versus incongruent gesture primes as compared to no prime. In the congruent gesture-prime conditions, each metaphor was preceded by a gesture that represented the schema of the subsequent metaphor whereas this gesture was not compatible with the schema of the subsequent metaphor in the incongruent gesture-prime conditions. Results showed that a higher proportion of sentences were judged to be sensible in the congruent gesture-prime conditions compared to no-prime and incongruent gesture-prime conditions. Also, response times of sensibility judgements were shorter in congruent gesture-prime conditions compared to no-prime and incongruent gesture-prime conditions. These results suggest that metaphor schema affects metaphor comprehension through the activation of metaphorically-relevant information and suppressing irrelevant information.

    The roles of gestural and symbolic schematizations in inhibition as a component of executive functions
    (Springer, 2023) Khatin-Zadeh, Omid; Farina, Mirko; Yazdani-Fazlabadi, Babak; Hu, Jiehui; Trumpower, David; Marmolejo-Ramos, Fernando; Farsani, Danyal
    The role of gestural schematization in enhancing thinking processes has been the subject of a large body of works. In this process, contextually unimportant or irrelevant information related to a concept (or a system of concepts) is deleted or ignored, while relevant spatial information is maintained. This process is a special type of inhibition, which is one of the key components of executive functions. In this short paper, it is suggested that gestural schematization is a special type of symbolic schematization, a much more general process through which irrelevant information related to features of a concept (or a system of concepts) is suppressed, while relevant information (spatial and non-spatial) is maintained. Through symbolic schematization, abstract structural similarity between two concepts or between two systems of concepts can be discovered. In this way, an individual’s knowledge about the first situation can be generalized to the second situation. Symbolic schematization is the basis of abstraction, knowledge generalization, and knowledge development. This is particularly the case with abstract mathematical thinking. This proposal offers a picture of cognitive mechanisms through which knowledge of abstract mathematical concepts is created and developed in the mind.
