Language production––far from happening in the vacuum––is shaped by socio-emotional and thematic contexts and the goals and qualities of social interactions. This symposium explores how semantic, social, and emotional aspects shape language production at different levels of granularity, from the access to the mental lexicon to free verbal interactions. The symposium kicks off with three talks exploring the continuous naming paradigm, known to induce cumulative semantic interference (CSI), i.e., slower naming with each additional member of a (semantic) category being named. Marisha Herb presents pooled analyses of seven experiments and introduces cosine similarity as a unifying measure to quantify different types of semantic relations. The next two talks use browser-based applications of the same paradigm to examine subtypes of thematic relations that have received comparably little empirical attention so far: Dimitra Tsiapou investigates emotional language production, exploring how emotional action verbs (related to basic emotions happiness, sadness, fear, anger, disgust, surprise) elicit an emotion-specific CSI effect. Annika Speckhahn examines social context in language production, demonstrating how words from associatively related social categories (children’s play, conflict, parenthood) shape the CSI effect. Shifting focus to interactive language use, Kirsten Stark presents findings from three online experiments on verbal deception and honesty. She shows that while lying is slower than truth-telling, truth-telling is far from being immune to the social-deceptive context, highlighting the role of planning, control, and monitoring processes involved. Finally, Giusy Cirillo takes a further turn towards real-life interactions and explores how early vocabulary acquirement is shaped by social alignment between toddlers and caregivers: Using a multiphase experimental paradigm with free interaction, referential, and object recognition tasks, she explores how 22- and 30 month-old toddlers’ early language acquisition is modulated by the way caregivers adapt their language to the toddler’s age and knowledge. Throughout these talks, the symposium aims to showcase innovative experimental, browser-based, and response-time sensitive methods for studying language production in both experimental and real-life contexts and various age groups.

The symposium will be chaired by Kirsten Stark and Prof. Dr. Rasha Abdel Rahman1 (rasha.abdel.rahman@hu-berlin.de). Prof. Abdel Rahman will not give a talk herself.

Previous research has shown that lexical selection is not only affected by shared semantic features, but also by associative or thematic relations between items (Rose & Abdel Rahman, 2016; Lin, 2022). Additionally, social effects involving communicative partners have been reported in the continuous naming task (e.g., Kuhlen & Abdel Rahman, 2017; Hoedemaker et al., 2017) and other paradigms (e.g, Diveica et al., 2024; Arioli et al., 2021). In the present study, participants named photographs of scenes from 16 social interaction contexts (e.g., children's play, conflict, parenthood) by producing the displayed social actions (e.g., to argue) in a continuous naming task in an online experiment with typed responses. Pilot data shows a significant cumulative semantic interference effect with an increase in response latencies of ~36 ms with each consecutive word from the same social interaction context. For the final dataset and a replication study with spoken instead of typed responses we predict comparable interference effects, which would enhance our understanding of the role of social relations during language production.
