The sound of motion in spoken language: visual information conveyed by acoustic properties of speech

Language is generally viewed as conveying information through symbols whose form is arbitrarily related to their meaning. This arbitrary relation is often assumed to also characterize the mental representations underlying language comprehension. We explore the idea that visuo-spatial information can be analogically conveyed through acoustic properties of speech and that such information is integrated into an analog perceptual representation as a natural part of comprehension. Listeners heard sentences describing objects, spoken at varying speaking rates. After each sentence, participants saw a picture of an object and judged whether it had been mentioned in the sentence. Participants were faster to recognize the object when motion implied by speaking rate matched the motion implied by the picture. Results suggest that visuo-spatial referential information can be analogically conveyed and represented.     

Teachers facing school failure: the social valorization of effort in the school context

This paper describes two studies concerning teachers’ classroom interventions facing school failure. The role of two main variables is investigated: the lack of effort as a cause of failure students are held responsible for by teachers, and teacher’s social representations of intelligence. The first study (Study 1) explored the impact of “lack of effort” causal attribution for student’s failure on the intervention strategies adopted by 122 high school teachers. Study 2 analyzed the impact of social representations of intelligence, held by 202 high school teachers, on “lack of effort” causal inference and on behavioral interventions. Results highlight that teachers mostly choose more severe educational interventions with retributive purpose when failure is ascribable to an absence of effort expenditure by the student. Moreover, the findings support the role of teachers’ social representations of intelligence in failure explanations and in educational practices, showing that “lack of effort” attribution and practices with retributive purpose are predicted by the social representation of intelligence “as a gift”. Results are analyzed and discussed by considering the effort as a normative parameter of the school environment. This research was supported financially in part by MURST “University funds, 2004 (Ex 40%)”. Portions of these results were presented at the 8th International Conference on Social Representations, Rome.     

Caregiving representations in war conditions: Associations with maternal trauma,mental health,and mother–infant interaction

Risk features in mothers’ caregiving representations remain understudied in dangerous environments where infants most urgently need protective parenting. This pilot study examines the feasibility of a novel coding system for the Parent Development Interview (PDI) interview (ARR, Assessment of Representational Risk) in assessing 50 war-exposed Palestinian mothers’ caregiving representations. First, we explored the content and structure of risks in the representations. Second, we examined associations between the high-risk representations, mothers’ pre- and postnatal exposure to traumatic war events (TWE), depressive and post-traumatic stress disorder (PTSD) symptoms, and self-rated emotional availability (EA) with their 1-year-old infants. Following three dimensions of high-risk caregiving representations were identified: self/dyadic dysregulation, unavailable, and fearful. Mothers’ prenatal depressive symptoms were associated with dysregulating and fearful representations, and their postnatal PTSD with fearful representations. TWE were not associated with the high-risk representations. Moreover, mothers of boys reported more fearful representations, and mothers with financial difficulties reported more unavailable representations. TWE and high-risk representations were not associated with EA. However, qualitative analysis of the representations indicated risks in the mother–infant relationship. Further, older mothers and mothers with postnatal PTSD reported lower EA. Cultural variance in caregiving representations and the use of self-report measures among traumatized mothers are discussed.     

Incorporating Demographic Embeddings Into Language Understanding

Meaning depends on context. This applies in obvious cases like deictics or sarcasm as well as more subtle situations like framing or persuasion. One key aspect of this is the identity of the participants in an interaction. Our interpretation of an utterance shifts based on a variety of factors, including personal history, background knowledge, and our relationship to the source. While obviously an incomplete model of individual differences, demographic factors provide a useful starting point and allow us to capture some of this variance. However, the relevance of specific demographic factors varies between situations—where age might be the key factor in one context, ideology might dominate in another. To address this challenge, we introduce a method for combining demographics and context into situated demographic embeddings—mapping representations into a continuous geometric space appropriate for the given domain, showing the resulting representations to be functional and interpretable. We further demonstrate how to make use of related external data so as to apply this approach in low‐resource situations. Finally, we show how these representations can be incorporated into improve modeling of real‐world natural language understanding tasks, improving model performance and helping with issues of data sparsity.     

Social representations of health and illness: the case of the Chinese community in England

This paper reports results from a qualitative study on social representations of health and illness among the Chinese community in England. It is assumed that representations of health and illness are grounded in cultural frameworks and are constructed through communication, social interaction and the practices of daily life. Our findings show that in spite of differences related to age and degrees of acculturation, Chinese people in England share a common representational system with respect to health and illness. This system is based on the traditional notions of “balance” and “harmony” between the interdependent forces of Yin and Yang. Health results from balance, whereas illness is brought about by disequilibrium. It is through these traditional Chinese concepts that Western biomedical knowledge is incorporated, producing a mixed representational field where Chinese and Western knowledge co‐exist. This representational field is transmitted through the most fundamental dimensions of culture: food, language and kinship relations. We conclude by showing that social representations of health and illness are inseparable from the struggles over identity experienced by the Chinese people in England.

Reading the Public: Political Action and Its Relationship to Constructions of Political Disagreement and Opinion Climate in the Context of Brexit

This study applied a social representations approach to investigate the ways in which constructions of perceived political disagreement and the prevailing opinion climate were implicated in people's construals of political participation in the context of the United Kingdom European Union referendum of 2016. Interviews were conducted with 19 residents of the United Kingdom who voted to remain in the referendum, located in constituencies which represented diverse opinion climates in relation to the referendum. Thematic analysis of the data revealed that public opinion was a dilemmatic social representation; it was inscrutable and often ill-informed but also volatile and disruptive, which left open the possibility of it moving towards a more pro-EU position. Importantly, constructions of a polarized and dysfunctional political system worked to sustain a mode of political engagement which prioritized and positioned as efficacious individual rather than collective anti-Brexit political behavior. This implies that people may prefer different types of political participation depending on the opinion climate which they occupy and the way in which they construe it. Findings are discussed in relation to previous work linking meta-representations to political behavior and expression, and the implications of the findings for emergent forms such as Brexit are elaborated.
