Intro. A full account of speech perception requires explaining how listeners organize the acoustic signal into speech objects (perceptual organization) and how listeners use their memory for language to impart meaning to the speech objects (linguistic memory). Traditionally these mechanisms have been investigated separately, and thus theorized as…

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…

Infants are born highly sensitive to the natural patterns found in languages. They use their perceptual sensitivity to acquire detailed information about the structure of languages in their environment. To date, most studies of infant perception and early language acquisition have investigated spoken/auditory languages and hearing infants (e.g.…

Challenges in peer interaction are commonly associated with autism, both within research literature and through first-person accounts. Related intervention studies have tended toward a skills-based approach that emphasizes remediating perceived social deficits in the autistic individual, with most of the literature focusing on children who are…

Results from previous research studies suggest that inclusive settings benefit all learners. However, general education teachers often do not have built in supports within the classroom to meet the needs of students with disabilities. Implementing a sensory diet curriculum (SDC) is one instructional practice that addresses needs of students with…

This dissertation investigates the ways in which experience with lexical tone influences the perception of musical melody, and how musical training influences the perception of lexical tone. The central theoretical basis for the study is a model of perceptual learning, Reverse Hierarchy Theory (Ahissar et al., 2009), in which cognitive processes…

Spatial ability is important to science, technology, engineering, and math (STEM) success, but spatial talents are rarely developed in schools. Likewise, the gifted may become STEM innovators, but they are rarely provided with pedagogy appropriate to develop their abilities in schools. A stratified random sample of volunteer participants (n = 75)…

The Visual-Spatial Chemistry Specific (VSCS) assessment tool was developed to test students' visual-perceptual skills, which are required to form a mental image of an object. The VSCS was designed around the theoretical framework of Rochford and Archer that provides eight distinct and well-defined visual-perceptual skills with identified problems…

Individuals with autism spectrum disorders (ASD) have documented sensory processing difficulties across the lifespan; however there is limited empirical support for the sensory-based interventions that have become ubiquitous with the population. This study was conducted to address this need and examine the effect of sensory-based interventions on…

In 2005, the U. S. Department of Education estimated that 44% of the 3 million students enrolled in non-traditional, that is, non-academic, adult education programs were English language learners. Yet, because of the overt focus that tends to be placed on oral communication, little has been done to document how these learners might view themselves…
