911 calls reporting the mysterious disappearance of a child may contain information critical to law enforcement. If this information is untruthful, valuable resources can be misdirected and precious time may be lost. Therefore, the current study examined verbal cues of veracity and deception in 911 calls placed by caregivers of missing children.…

External representations powerfully support and augment complex human behavior. When navigating, people often consult external representations to help them find the way to go, but do maps or verbal instructions improve spatial knowledge or support effective wayfinding? Here, we examine spatial knowledge with and without external representations in…

The inclusion of private events in the philosophy of our science is integral to avoid dualism and remain objective rather than making assumptions about an unseen mind. However, the inclusion of behaviors and stimuli which cannot be observed in an analysis poses obvious issues. One established method of studying covert behavior is to examine tasks…

The early language environment, especially high-quality, contingent parent-child language interactions, is crucial for a child's language development and later academic success. In this secondary analysis study, 89 parent-child dyads were randomly assigned to either the Music Together® (music) or play date (control) classes. Children were 9- to…

Background: Children with Tourette syndrome (TS) have historically experienced problems in academic and social settings, yet their language and communication abilities have not been extensively researched. Aims: This scoping review maps the literature on the oral language and social communication abilities of children with TS in order to describe…

The purpose of the study was to evaluate the effects of tact and match-to-sample instructions on the increase and maintenance of intraverbal responses to subcategorical questions (i.e., naming multiple items in a subcategory of a category). Three Chinese children on the autism spectrum (2 boys, 1 girl, aged 6-8 years old) participated in this…

Procedural fidelity refers to the degree to which procedures for an assessment or intervention (i.e., independent variables) are implemented consistent with the prescribed protocols. Procedural fidelity is an important factor in demonstrating the internal validity of an experiment and clinical treatments. Previous reviews evaluating the inclusion…

Multiple contemporary theories emphasize the quantity and quality of child vocalizations for promoting spoken language acquisition. Yet, empirical evidence for facilitating vocal development is strikingly lacking including for children with autism spectrum disorder (ASD) who have difficulty developing language. We evaluate use of contingent…

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…

Early writing includes both transcription skills (e.g., handwriting and spelling) and composing skills (e.g., the generation, manipulation, and translation of ideas into writing), yet early composing is not as well understood in academic research or by classroom educators. This study seeks to understand 1) how children retained or modified core…

Previous research has shown that contingent vocal imitation has a reinforcing effect on vocalizations emitted by children. Nevertheless, the precise contingencies that have a reinforcing effect on vocalizations remain unclear. This study examined the effects of five conditions (contingent vocal imitation, contingent interaction, noncontingent…

The current study examined vocalizations that occurred during training of the Picture Exchange Communication System for three U.S. preschool-age participants with autism spectrum disorder. In Phase IV, the protocol incorporates a delay to reinforcement in an effort to encourage vocalizations; however, the manual does not suggest additional…

In this paper, we aimed to examine what characterizes teachers' interactions with children in micro-level transitions in Norwegian preschools. We used video and observed transitions at the micro level, such as between meal and sleeping time, and between playing and meals. The participants were 22 teachers from 22 classrooms in 17 preschools. We…

Purpose: Individuals with aphasia identify discourse-level communication (i.e., language in use) as a high priority for treatment. The central premise of most aphasia treatments is that restoring language at the phoneme, word, and/or sentence level will generalize to discourse. However, treatment-related changes in discourse-level communication…

Rodriguez et al. (2022) discovered that teaching four component skills was sufficient to facilitate the emergence of intraverbal tacts across four applications with three participants. Our study replicated and evaluated an extension of this procedure that was directed at facilitating intraverbal tacts when a child learns the component skills but…
