Over the past two decades, we have witnessed an abundance of student protests at colleges and universities in the United States. Many of these protests cluster around the issues of white supremacy and anti-Black racism as they function in higher education settings--issues that have historically and contemporarily plagued United States colleges and…

As humans, we use language with ease and speed, solving the complex computational problem of processing form and meaning seemingly without effort. This dissertation studies how the properties of language enable us to achieve this, by investigating what is computationally difficult about language, and what is easy. We first investigate the…

Segmentation is a cornerstone of language processing across levels of linguistic analysis, and yet, standard models of linguistic memory leave the role of higher-order segments in online comprehension understudied. This dissertation advances the Context-Sensitive Encoding (CSE) hypothesis: that implicit prosodic boundaries (Bader, 1998; J. Fodor,…

Prospective memory (PM), the ability to remember to execute an intention in the future, is critical for the performance of everyday tasks important for independence and quality of life. PM failures are associated with negative health, financial, and social outcomes, and are more frequent with increased age and can be even greater for older adults…

Concept maps are a popular learning activity that have successfully demonstrated student learning outcomes. Research suggests that concept mapping has a positive effect on recognition, recall, and transfer. Likewise, researchers in cognitive psychology have shown the value of referencing oneself with a concept. Known as the self-reference effect,…

Learning in a multimedia environment puts many demands on a learner's limited working memory, but this can become even more demanding as the level of distraction increases in a lesson. What has not been investigated much in previous literature is whether higher levels of distraction in lessons are more harmful to some learners than others. This…

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…

Executive functions are higher order mental processes individuals use during academic tasks (Diamond, 2013). Few studies examined executive functions in braille reading. Additionally, most studies located by the primary researcher were studies analyzing group differences between individuals with visual impairments and those who are sighted and…

The appropriate amount of first language (L1) and second language (L2) to use in L2 learning has been constantly debated (e.g., Cummins, 2007; Hall & Cook, 2012). This study situates the debate of L1 and L2 use in the context of vocabulary learning from reading. By examining the potential moderating factors on the comparison of L1 and L2…

Across three separate investigations, this dissertation documents work examining the role of higher-order processes and cognitive effort during the top-down compensatory repair of degraded speech, specifically perceptual restoration. Perceptual restoration is a phenomenon where a listener can perceptually restore or repair speech…

Reading is a fascinating cognitive process through which individuals perceive arbitrary symbols on a page and turn them into vivid mental representations of text. Most available evidence supports an embodied explanation for how readers are capable of such representations--they recruit supralinguistic brain regions in order to mentally simulate the…

Memory is expressed in multiple functionally and anatomically distinct systems that interact over the course of learning and during the retrieval of information about the world. One method to determine the kind of memory representation (episodic and/or procedural) guiding behavior is to look at the expression of expectations (i.e., predictions) in…

According to cognitive psychologists, consistent practice (i.e., tasks with a high degree of similarity) of a skill leads to the development of automaticity, with the degree of automatization being increased if the practice also involves exact repetition. Practice is skill specific, meaning that practicing one skill does not automatize related…

A high-quality, foundational education offers lifelong benefits for young children. The problem is that working memory in pre-school-aged children is declining and could be impaired by the extraneous cognitive load imposed during engagement with screen media apps and/or preschool programs. Although the pedagogical practices associated with…

Extensive evidence supports the effectiveness of retrieval practice as a powerful method for promoting long-term learning. For students to obtain the maximum benefit from retrieval practice they need to incorporate the strategy into their study routines as a learning tool that is used early and often. Unfortunately, many students avoid retrieval…
