Mathematics is crucial to the educational and vocational success of students. The concrete-representational-abstract (CRA) approach is a method to teach students mathematical concepts. The CRA involves instruction with manipulatives, representations, and numbers only in different lessons (i.e., concrete lessons include manipulatives but not…

Individuals with intellectual and developmental disabilities have increased risk for developing challenging behavior. One particularly dangerous topography of challenging behavior is rapid eating. Rapid eating can lead to increased risk for choking and obesity as well as negatively impact social interactions during mealtimes (Anglesea et al.,…

Children with autism spectrum disorder (ASD) display difficulties with response to joint attention in natural settings but often perform comparably to typically developing (TD) children in experimental studies of gaze following. Previous work comparing infants at elevated likelihood for ASD versus TD infants has manipulated aspects of the gaze…

The purpose of this study is to explore the effects of an affective recommendation system on the developmental trajectories of prospective teachers' emotional patterns, integrated with a Simulated Virtual Classroom (SVC) platform called SimInClass. SVC exposes teachers to a range of student discourses in the form of unexpected stimuli. Fifteen…

Recent work has shown significant sublexical effects of long-term memory in nonword repetition (NWR) using a dichotomous consonant age of acquisition (CAoA) variable (Moore, 2018; Moore, Fiez, and Tompkins, 2017). Performance consistently decreased when stimuli comprised consonants acquired later versus earlier in speech development. To address…

Children with autism spectrum disorder (ASD) often demonstrate difficulty communicating with others, and this may impact the extent to which they can engage in language during play. Previous researchers have used interventions to increase commenting during play with caregivers, siblings, and adult play partners. In these previous studies,…

Early and late bilinguals both differ in the speed with which they comprehend language or in their processing of sentences compared to monolinguals. This is possibly a result of cross-language interference, differential allocation of cognitive resources, or some other difference in language-dependent processes. This dissertation presents research…

Purpose: The purpose of the current study was to examine inhibition of irrelevant information in younger and older English monolingual and Spanish--English bilingual adults. Method: Sixty-one participants divided into four groups: 15 younger English monolinguals, 16 younger Spanish-English bilinguals, 15 older English monolinguals, and 15 older…

Scientific enquiry is a creative process, commonly beginning with a question or problem, then generating a tentative answer or solution, and testing it. In the classroom, the question, perhaps in the form of a problem, is generally given, ready-made, to students by the teachers. With the aim of providing young students with a fuller experience of…

Although reducing visual input to emphasize auditory cues is a common practice in pediatric auditory (re)habilitation, the extant literature offers minimal empirical evidence for whether unisensory auditory-only (AO) or multisensory audiovisual (AV) input is more beneficial to children with hearing loss for developing spoken language skills. Using…

Purpose: Bilingual individuals have been shown to be more proficient on visual tasks of inhibition compared with their monolingual counterparts. However, the bilingual advantage has not been evidenced in all studies, and very little is known regarding how bilingualism influences inhibitory control in the perception of auditory information. The…

Astronomy, a captivating field that draws upon science, mathematics, and engineering, has traditionally relied on visual representations to convey the wonders of the cosmos. While this approach effectively engages the sighted population, the use of imagery can exclude individuals with blindness or visual impairment (B/VI). Astronomical research is…

Aspectual and mood morphology are vulnerable domains in adult heritage speakers. This paper investigates the root of such vulnerability within the domain of Turkish evidentiality system by comparing 20 second-generation adult and 20 school-age child Turkish heritage speakers to 20 first-generation immigrants (main input providers for child…

Most tasks test memory within the same day, however, most forgetting occurs after 24 h. Further, testing memory for simple words or objects does not mimic real-world memory experiences. We designed a memory task showing participants video clips of everyday kinds of experiences, including positive, negative, and neutral stimuli, and tested memory…

Purpose: Augmentative and alternative communication (AAC) is an intervention approach that can promote communication and language in children with multiple disabilities who are beginning communicators. While a wide range of AAC technologies are available, little is known about the comparative effects of specific technology options. Given that…
