Effective communication is vital in both social and professional contexts, yet the nuanced relationship between nonverbal communication (NVC) and affectivity, particularly in relation to demographic factors, has not been fully understood. The lack of clarity in how these elements interact poses a challenge in developing tailored communication…

Nudge theory, a strategy to influence decision-making, holds promise for enhancing an adult's use of evidence-based strategies during a read-aloud experience with a young child. This study examined the effectiveness of a nudge theory approach in increasing adult gesture use during a book-reading activity with a young child. Notably, 31 U.S.…

Studying early language development has been a challenging task throughout the years. Earlier studies mostly documented language competence only after toddlers had started producing their first words. Theoretical and methodological advances in this domain brought about more sophisticated ways of probing into early development by exploiting overt…

As technology becomes ubiquitous in the homes of many families, children learn to incorporate touchscreen devices into their everyday activities. The present study explored young children's role in shaping their gaming experience to maintain social interactivity. Twenty-nine children at 2.5 years old in the U.S. played a non-educational game on a…

Meaningful gestures enhance degraded speech comprehension in neurotypical adults, but it is unknown whether this is the case for neurodivergent populations, such as autistic individuals. Previous research demonstrated atypical multisensory and speech-gesture integration in autistic individuals, suggesting that integrating speech and gestures may…

A fundamental challenge in the cognitive sciences is discovering the dynamics that govern behavior. Take the example of spoken language, which is characterized by a highly variable and complex set of physical movements that map onto the small set of cognitive units that comprise language. What are the fundamental dynamical principles behind the…

Although previous research provides insights into how gestures function as a pedagogical tool, relatively little is known about how gesture is related to language, together creating a key meaning-making teaching resource. Drawing on the system of logico-semantic relations in Systemic Functional Linguistic theory and McNeill's description of…

Background: Initiating meaningful moments of interaction with people with profound intellectual disabilities can prove to be difficult for support staff. Exploring the behaviour of support staff that precedes the initiations of behaviour by people with profound intellectual disabilities helps to shed light upon the potential facilitating effects…

Multiple movement methods have been used in the music classroom for educational and research purposes. Laban Movement Analysis (LMA) is a movement framework that has been used with conductors, but there is limited research using Laban movements with K-12 band ensemble students. The purpose of this study was to investigate the effect of Laban…

Successive matching-to-sample (S-MTS) with a go/no-go response requirement has previously produced equivalence classes with nonverbal auditory stimuli among college students. When participants are required to talk aloud during posttests (protocol analysis), their verbal behavior tends to match their selection performance. However, in some cases,…

Language plays a fundamental role in enabling flexible, goal-directed behaviour. This study investigated whether the contribution of language to instruction encoding is modulated by the expression of autism traits, as measured by the Autism Spectrum Quotient (ASQ) questionnaire. Participants (N = 108) completed six choice reaction time tasks, with…

Societal expectations for social-emotional behavior differ across sexes; however, diagnostic definitions of autism do not account for this when delineating "typical" versus "atypical." This study examines sex differences in autism in one behavior associated with strong gender biases: smiling. Computer vision was used to…

Objective: In preterm and very low birth weight (VLBW) infants, attention-related problems have been found to be more pronounced and emerge later as academic difficulties that may persist into school age. In response, based on three attention networks: alerting, orienting, and executive attention, we examined the development of attention functions…

Purpose: The present study explored the extent to which early prelinguistic communication skills predict expressive language in toddlers with autistic siblings (Sibs-autism), who are known to be at high likelihood for autism and language disorder, and a comparison group of toddlers with non-autistic older siblings (Sibs-NA). Method: Participants…

The accurate detection of children's truthful and dishonest reports is essential as children can serve as important providers of information. Research using automated facial coding and machine learning found that children who were asked to lie about an event were more likely to look surprised when hearing the first question during an interview…
