Lab Meets World: the Case for Use-Inspired Basic Research in Affective Science

We join others in envisioning a future for affective science that addresses society's most pressing needs. To move toward this vision, we consider a research paradigm that emerged in other disciplines: use-inspired basic research. This paradigm transcends the traditional basic-applied dichotomy, which pits the basic goal of fundamental scientific understanding against the applied goal of use in solving social problems. In reality, these goals are complementary, and use-inspired basic research advances them simultaneously. Here, we build a case for use-inspired basic research-how it differs from traditional basic science and why affective scientists should engage in it. We first examine how use-inspired basic research challenges problematic assumptions of a strict basic-applied dichotomy. We then discuss how it is consistent with advances in affective science that recognize context specificity as the norm and consider ethical issues of use being a complementary goal. Following this theoretical discussion, we differentiate the implementation of use-inspired basic research from that of traditional basic science. We draw on examples from recent research to illustrate differences: social problems as a starting point, stakeholder and community engagement, and integration of research and service. In conclusion, we invite affective scientists to embrace the "lab meets world" perspective of use-inspired basic research as a promising pathway to real-world impact.

Caregiver linguistic alignment to autistic and typically developing children: A natural language processing approach illuminates the interactive components of language development

BACKGROUND

Language development is a highly interactive activity. However, most research on linguistic environment has focused on the quantity and complexity of linguistic input to children, with current models showing that complexity facilitates language in both typically developing (TD) and autistic children.

AIMS

After reviewing existing work on caregiver engagement of children's utterances, we aim to operationalize such engagement with automated measures of linguistic alignment, thereby providing scalable tools to assess caregivers' active reuse of their children's language. By assessing the presence of alignment, its sensitivity to the child's individual differences and how well it predicts language development beyond current models across the two groups, we showcase the usefulness of the approach and provide initial empirical foundations for further conceptual and empirical investigations.

METHODS

We measure lexical, syntactic and semantic types of caregiver alignment in a longitudinal corpus involving 32 adult-autistic child and 35 adult-TD child dyads, with children between 2 and 5 years of age. We assess the extent to which caregivers repeat their children's words, syntax, and semantics, and whether these repetitions predict language development beyond more standard predictors.

RESULTS

Caregivers tend to re-use their child's language in a way that is related to the child's individual, primarily linguistic, differences. Caregivers' alignment provides unique information improving our ability to predict future language development in both typical and autistic children.

CONCLUSIONS

We provide evidence that language development also relies on interactive conversational processes, previously understudied. We share carefully detailed methods, and open-source scripts so as to systematically extend our approach to new contexts and languages.

Word Teaching Strategies in Story Reading for Preschool Children

Abstract Shared book reading (SBR) as a teaching practice produces significant effects on development of verbal repertoires in children, especially when associated with strategies of explicit vocabulary teaching. This study aimed to test the cumulative effects of using word teaching strategies, during SBR sessions, on word learning by preschool children. Three sessions of SBR of the same story and a session of complementary activity about the words of the story read were carried out in a class of 13 children aged 4 to 5 years. It was identified significant children’s gains, between pre and post-test, in matching-to-sample tasks for nouns and in naming tasks, both for nouns and for verbs. The results confirm the effectiveness of using word teaching strategies during SBR and their feasibility in the natural classroom context.
