Our visual system samples external information, adjusts its sensitivity and constructs a stable representation of the world that allows us to perceive and interact with objects in our environments. Visual information with different levels of complexity is processed through the hierarchically organized visual cortical areas. This dissertation…

The genetic diversity contained in a population can be used to engage the audience in an understanding of human genotypes and phenotypes. With a series of simple examples of well-documented sensory phenotypes related to the perception of colour, aromas or food preference, the diversity of the audience can be easily explored. The collecting of…

The researchers designed a delayed intervention start randomized controlled trial to compare improvements in functional communication following augmentative and alternative communication (AAC) interventions. The study compared outcomes from function-based applied behavior analytic (ABA) and eclectic non-ABA forms of classroom-based communication…

Objective: This study seeks to understand the experiences of college student as they completed their education during the COVID-19 lockdown. Participants: Students at a large 4-year college in Midwestern USA. Methods: We conducted a photo-survey of students' experiences during the lockdown. Student researchers and faculty collaborated to analyze…

Verbs serve as the architectural centerpiece of sentences, making verb learning pivotal for language acquisition. Verb learning requires both the formation of a verb-action mapping and the abstraction of relations between an object and its action. Two competing positions have been proposed to explain the process of verb learning: (a) seeing a…

The fact that the violin is a fretless instrument brings along intonation problems both in its performance and in its education. The introduction of technology into educational environments day by day, has led to the need to try different methods besides the traditional methods for solving intonation problems. The aim of this study is to examine…

Money skills are important for students with autism spectrum disorder (ASD) to successfully live independently. A crucial first step is teaching them money identification. The purpose of this study was to examine the efficacy of using TouchMath money (TMM) to teach middle school students with ASD to count money. A multiple probe design across…

Although statistical learning (SL) has been studied extensively in developmental dyslexia (DD), less attention has been paid to other fundamental challenges in language acquisition, such as cross-situational word learning. Such investigation is important for determining whether and how SL processes are affected in DD at the word level. In this…

Purpose: The use of attentional resources is an important cognitive indicator of reading engagement but it is unknown how this is influenced by linguistic cues. We designed two experiments to investigate whether shifts in narrative perspectives occupy more of the attention of readers and engage them more in the text. Methods: Experiment 1 employed…

This study explores the complexity of language learner silence in the female Saudi Arabian university English as a foreign language (EFL) classroom. To this end, a combination of two methodologies was used. First, a total of 296 students from 12 EFL classrooms were observed using the COPS structured observation scheme (King, 2013a, b) to measure…

Covert contrast is the statistically reliable distinction between target language phonemes produced in the process of language acquisition that is nevertheless not perceived by a native speaker of that language. This paper examines the acquisition of contrasts in four Najdi Arabic fricatives, /s/, /[voiceless palato-alveolar fricative]/,…

Students in a typical instrumental analysis course may learn more than 30 analytical techniques. There are more than 150 components associated with the instrumentation that they learn. To help students organize this large amount of information, we classified these components into four categories: sources, samples, discriminators, and detectors. In…

Introduction: Visual model comprehension and application are important for success in science, technology, engineering, and mathematics (STEM) courses. As educational materials shift to primarily digital content with dynamic interactive visuals, students with visual impairments are at risk for being disadvantaged, since few interactives are born…

The majority of research examining infants' decontextualized word knowledge comes from studies in which words and pictures are presented simultaneously. However, comprehending utterances about unseen objects is a hallmark of language. Do infants demonstrate decontextualized absent object knowledge early in the second year of life? Further, to what…

The occurrence of an unexpected, infrequent sound in an otherwise homogeneous auditory background tends to disrupt the ongoing cognitive task. This "deviation effect" is typically explained in terms of attentional capture whereby the deviant sound draws attention away from the focal activity, regardless of the nature of this activity.…
