Purpose: Bound morphemes are challenging for children who are deaf and hard of hearing (DHH) to acquire and to use successfully. The challenge arises in part from limited access to spoken word forms as a result of reduced audibility during perception, but successful comprehension requires access to both the morphological forms and the mapping…

Discrete trial teaching (DTT) is a common teaching methodology used within intervention for autistics/individuals diagnosed with autism spectrum disorder (ASD). Practice recommendations related to using DTT for receptive language instruction includes the desired size of the array of stimuli to be presented. Some recommendations include ensuring…

Visual perspective-taking is the ability to perceive the world from another person's perspective, and research on visual perspective-taking ability in children with autism spectrum conditions yielded inconsistent results. To solve a visual perspective-taking task, people can mentally rotate themselves to another person's location (embodied…

Background and aims: Although young children's gaze behaviors in experimental task contexts have been shown to be potential biobehavioral markers relevant to autism spectrum disorder (ASD), we know little about their everyday gaze behaviors. The present study aims (1) to document early gaze behaviors that occur within a live, social interactive…

Eye tracking research technologies are often used to study how individuals attend visually to different types of AAC displays (e.g. visual scene displays, grid displays). The assumption is that efficiency of visual search may relate to efficiency of motor selection necessary for communication via aided AAC; however, this assumption has not…

"Stimulus over-selectivity" describes a phenomenon in which an individual responds only to a subset of the stimuli present in the environment and, thus, may restrict learning. This study aimed to develop understanding of the nature and role of over-selectivity in autism spectrum disorder (ASD) by analyzing the relationship of…

Oral retelling portrays what one understands from reading or listening to a text. The retold stories of children with autism spectrum disorder (ASD) often show macrostructural (overall story structure) difficulties. The study's purpose was to compare macrostructure oral story retelling, after reading (visual modality) or listening (auditory…

This study provides an example of using single case experimental design to guide data-driven, low-inference interventions for an individual using customized displays on a speech-generating device and can serve as an example for interventionists who need to compare intervention strategies to identify approaches that are most appropriate for a…

Purpose: Many aided augmentative and alternative communication (AAC) systems require the use of an external display that is represented via a visual modality. It is critical to evaluate and understand visual-perceptual processing in individuals with disabilities who could benefit from AAC. One way to evaluate how individuals process visual…

This study investigated developmental memory capacity through picture span and feature binding. Participants included third grade students and college age adults with typical development. Picture span was used to assess working memory capacity when participants were asked to identify, locate, and sequence common visual-graphic symbols from…

Purpose: The purpose of this study was to examine whether children's identification of misarticulated words as real objects was influenced by an inherent bias toward selecting real objects or whether a change in experimental conditions could impact children's selections. Method: Forty preschool children aged 4 years 0 months to 6 years 11 months…

We assessed nonword repetition (NWR) skills in 7-9 year-old children with dyslexia (dyslexia-only), developmental language disorder (DLD-only), co-occurring DLD+dyslexia, and typical development (TD) with a norm-referenced and an experimental task. The experimental task manipulated phonemic variability (dissimilarity among consonant phonemes…

According to prediction-based learning theories, erroneous predictions support learning. However, empirical evidence for a relation between prediction error and children's language learning is currently lacking. Here we investigated whether and how prediction errors influence children's learning of novel words. We hypothesized that word learning…

Purpose: This study compares online word recognition and prediction in preschoolers with (a suspicion of) a developmental language disorder (DLD) and typically developing (TD) controls. Furthermore, it investigates correlations between these measures and the link between online and off-line language scores in the DLD group. Method: Using the…

Bilingualism has been associated with a range of cognitive and language-related advantages, including the recognition that words can have different labels across languages. However, most previous research has failed to consider heterogeneity in the linguistic environments of children categorized as monolingual. Our study assessed the influence of…
