The aim of the article is to present ways in which gestures combine with the verbal layer of an utterance, thus reflecting embodied thinking and the rooting of abstract concepts in human bodily experience. The article discusses two different ways in which gestures, described in the literature as metaphoric, illustrate both linguistically expressed metaphors and abstract concepts that are not verbally expressed as metaphors. The data analyzed in this paper have been taken from speeches of politicians and other public figures.

Gestures are an integral part of in-person conversations and complement the meaning of the speech they accompany. The neural processing of co-speech gestures is supported by a mostly left-lateralized network of fronto-temporal regions. However, in contrast to iconic gestures, metaphoric as well as unrelated gestures have been found to more strongly engage the left and right inferior frontal gyrus (IFG), respectively. With this study, we conducted the first systematic comparison of all three types of gestures and resulting potential laterality effects. During collection of functional imaging data, 74 subjects were presented with 5 s videos of abstract speech with related metaphoric gestures, concrete speech with related iconic gestures and concrete speech with unrelated gestures. They were asked to judge whether the content of the speech and gesture matched or not. Differential contrasts revealed that both abstract related and concrete unrelated compared to concrete related stimuli elicited stronger activation of the bilateral IFG. Analyses of lateralization indices for IFG activation further showed a left hemispheric dominance for metaphoric gestures and a right hemispheric dominance for unrelated gestures. Our results give support to the hypothesis that the bilateral IFG is activated specifically when processing load for speech-gesture combinations is high. In addition, laterality effects indicate a stronger involvement of the right IFG in mismatch detection and conflict processing, whereas the left IFG performs the actual integration of information from speech and gesture.

Abstract Patients with schizophrenia spectrum disorders (SSD) exhibit an aberrant perception and comprehension of abstract speech-gesture combinations associated with dysfunctional activation of the left inferior frontal gyrus (IFG). Recently, a significant deficit of speech-gesture mismatch detection was identified in SSD, but the underlying neural mechanisms have not yet been examined. A novel mismatch-detection fMRI paradigm was implemented manipulating speech-gesture abstractness (abstract/concrete) and relatedness (related/unrelated). During fMRI data acquisition, 42 SSD patients (schizophrenia, schizoaffective disorder, or other non-organic psychotic disorder [ICD-10: F20, F25, F28; DSM-IV: 295.X]) and 36 healthy controls were presented with short video clips of an actor reciting abstract or concrete sentences accompanied by either a semantically related or unrelated gesture. Participants indicated via button press whether they perceived each gesture as matching the speech content or not. Speech-gesture mismatch detection performance was significantly impaired in patients compared to controls. fMRI data analysis revealed that patients showed lower activation in bilateral frontal areas, including the IFG for all abstract > concrete speech-gesture pairs. In addition, they exhibited reduced engagement of the right supplementary motor area (SMA) and bilateral anterior cingulate cortices (ACC) for unrelated > related stimuli. We provide first evidence that impaired speech-gesture mismatch detection in SSD could be the result of dysfunctional activation of the SMA and ACC. Failure to activate the left IFG disrupts the integration of abstract speech-gesture combinations in particular. Future investigations should focus on brain stimulation of the SMA, ACC, and the IFG to improve communication and social functioning in SSD.

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.

In this article, we extend our previously suggested categorization of metaphors to literal statements, and categorize metaphorical and literal statements into four pairs of corresponding metaphorical and literal statements: (1) motion-based metaphorical/literal statements; (2) static space-based metaphorical/literal statements; (3) static object-based metaphorical/literal statements; (4) static event-based metaphorical/literal statements. Then, we report a study that investigated the use of metaphoric and iconic gestures with these corresponding categories during the retelling of a set of stories by a group of thirty participants. The participants listened to five audio short stories. Each story contained one statement of each metaphoric category and one statement of each literal category. After listening to each story, they retold it in their own language in front of a camera. The results showed that event-based metaphors and event-based literal statements were accompanied by the smallest number of metaphoric and iconic gestures. Furthermore, there was a significant similarity between each metaphorical category and its corresponding literal category in the number of gestures that were used with these categories. This similarity supports the idea that the mechanisms underlying the embodiment of metaphorical and literal statements are essentially similar.

This study aimed to examine the gestural embodiment of intensifiers in iconic and metaphoric gestures when these words are used with literal and metaphoric statements. We asked a group of Persian native speakers to listen to and then retell a set of Persian stories. In these stories, a number of intensifiers were used with literal and metaphoric sentences. The results showed that when an intensifier was used with a literal sentence, there was a higher probability of using an iconic or beat gesture than when there was no intensifier in the sentence. Also, when an intensifier was used with a metaphoric sentence, there was a higher probability of using a metaphoric or beat gesture than when the sentence contained no intensifier. These results suggested that an intensifier in a literal or metaphoric sentence can strengthen the mental simulation and the embodiment of objects, ideas, or situations. When an intensifier is used with a literal or metaphoric sentence, the strength of activation in the premotor areas may be amplified and spread to motor areas. In contrast, when no such intensifier is used in a literal or metaphoric sentence, there is a higher probability of simulation in premotor areas without spreading to the primary motor areas. The production of an internal force and expressing emphasis are two other possibilities that may explain the higher use of gestures with intensifiers.

This paper aims to develop a theoretical articulation of the different sense-making processes in human experience developed by Valsiner, Werner and McNeill. To this purpose, the mechanism of meaning-making - Pleromatization and schematization - developed by Valsiner; physiognomization in the perception of world developed by Werner; and the concept of metaphoricity as gestural representation of a mental construct developed by McNeill, are reviewed. In conclusion, a relationship between pleromatization, physiognomization and metaphoricity as phenomena - holistic, whole, organismic - that are integrated into the perception and construction of human experience, is established. On the other hand, a direct relationship between schematization, geometrical-technical perception and iconicity as another dimension - objectified, particularistic and cognitive - of making sense in human experience, is established.

The metaphorical motion of time can be expressed in gesture along either a sagittal axis—with the future ahead and past behind the speaker, or a lateral axis—with the past to the left and future to the right of the speaker (Casasanto & Jasmin in CL 23(4): 643–674, 2012). Adult English speakers, when gesturing about time, show a preference for lateral gestures with left-to-right directionality, consistent with the directionality of the reading-writing system in English (Casasanto & Jasmin in CL 23(4): 643–674, 2012). In this study, we asked how early children would show a preference for left-to-right lateral gestures and whether literacy skills would predict the production of such gestures. Our findings showed developmental changes in both the orientation and directionality of children’s gestures about time. Children increased their production of left-to-right lateral gestures over time, with a shift around ages 7–8. More importantly, literacy predicted children’s production of such lateral gestures. Overall, these results suggest that the orientation and directionality of children’s metaphorical gestures about time follow a developmental pattern that is largely influenced by changes in literacy.

Space and shape are distinct perceptual categories. In language, perceptual information can also be used to describe abstract semantic concepts like a \"rising income\" (space) or a \"square personality\" (shape). Despite being inherently concrete, co-speech gestures depicting space and shape can accompany concrete or abstract utterances. Here, we investigated the way that abstractness influences the neural processing of the perceptual categories of space and shape in gestures. Thus, we tested the hypothesis that the neural processing of perceptual categories is highly dependent on language context. In a two-factorial design, we investigated the neural basis for the processing of gestures containing shape (SH) and spatial information (SP) when accompanying concrete (c) or abstract (a) verbal utterances. During fMRI data acquisition participants were presented with short video clips of the four conditions (cSP, aSP, cSH, aSH) while performing an independent control task. Abstract (a) as opposed to concrete (c) utterances activated temporal lobes bilaterally and the left inferior frontal gyrus (IFG) for both shape-related (SH) and space-related (SP) utterances. An interaction of perceptual category and semantic abstractness in a more anterior part of the left IFG and inferior part of the posterior temporal lobe (pTL) indicates that abstractness strongly influenced the neural processing of space and shape information. Despite the concrete visual input of co-speech gestures in all conditions, space and shape information is processed differently depending on the semantic abstractness of its linguistic context.

Rhymed Ruminations(1940)Though moved to contribute to the war effort with his patriotic verse, Sassoon continued with the work of autognosis and the poetry of his private self throughout the war. Amidst the anxieties and distractions of wartime, much of his autognostic creative energy was directed to the composition of his prose memoirs, and since before the war began, he had been beset with nagging doubts about his poetic ability. By 1939 he had come to consider his poems in which he sought to express his true or inner self as ‘essentially private communications’. Choosing and arranging poems for Rhymed Ruminations, his only volume of new verse published during the war, he worried about the discrepancy between his autognostic approach and contemporary modernist tastes. In the war years he endured long spells of poetic inactivity, though he was by no means completely silent, writing more poetry than has been generally realized, most of it unpublished. The manuscripts containing this work – about forty poems – are marked by signs of his crisis of confidence; many lines are crossed out, there are scribbled amendments and convoluted additions, leaving the impression that he lacked the creative energy to complete this work or the confidence to see it published. When he considered a second wartime volume in 1944, he imagined a collection of only sixteen poems, a number soon reduced to twelve, and even then he doubted their cohesiveness as a sequence. And yet, in spite of all this doubt, he continued to write poetry.
