Mobile Cognitive Training For The Cognitive Symptoms Of Depression In Young Adults: A Double-Blind, Randomized Pilot Study With Active Control, Alice Grinberg
Mobile Cognitive Training For The Cognitive Symptoms Of Depression In Young Adults: A Double-Blind, Randomized Pilot Study With Active Control, Alice Grinberg
Dissertations, Theses, and Capstone Projects
Background: Depression is associated with a broad range of cognitive symptoms, including reduced attention, verbal learning and memory, executive functioning (EF), and processing speed (PS). Computerized cognitive training (CCT) has been shown to ameliorate the cognitive symptoms of depression. Younger adults, in particular, are understood to benefit more from CCT than older adults due to their greater capacity for neuroplasticity. However, several issues remain unclear about the effectiveness of CCT: (1) whether the benefits of CCT are driven by the specific content or by non-specific factors, such as engagement, motivation, novelty, and expectancy, which have been inadequately controlled in prior …
The Cognitive Thalamus: Source Analysis Of Scene Working Memory Delay Activity, Bernard A. Gomes
The Cognitive Thalamus: Source Analysis Of Scene Working Memory Delay Activity, Bernard A. Gomes
Dissertations, Theses, and Capstone Projects
Working Memory represents a limited-capacity store for maintaining information and manipulating the store's contents over a short period for the guidance of goal-directed behavior. Working Memory is an essential component of executive functions that are intricately associated with the prefrontal cortex (PFC). The PFC has been implicated in maintaining task-related information online for brief periods in the absence of relevant information. This active maintenance phase is called the delay period that occurs between encoding and retrieval of the stimulus. Previous studies have attempted to understand the relationship between working memory and the PFC, especially during the delay or maintenance phase …
Working Memory Training: Cognitive And Linguistic Implications In Adult English Language Learners, Deepti Wadhera
Working Memory Training: Cognitive And Linguistic Implications In Adult English Language Learners, Deepti Wadhera
Dissertations, Theses, and Capstone Projects
This study used a cognitive training paradigm to explore whether the same mechanisms of working memory underly conflict resolution in non-verbal and verbal domains in adult English language learners.The association between an individual’s Working Memory (WM) performance and their success in skills such as interference control, decision-making and language processing has been repeatedly highlighted by researchers in cognitive psychology and linguistic fields. Particularly, acquisition and use of a second language is one life experience in which WM ability seems valuable. However, when this association is put to the test in studies that train participants’ WM and measure transfer of these …
Bilingual Reading Fluency And Prediction: Heritage Language Versus Second Language, Olga Parshina
Bilingual Reading Fluency And Prediction: Heritage Language Versus Second Language, Olga Parshina
Dissertations, Theses, and Capstone Projects
The thesis presents the first comparative investigation of reading fluency and factors that affect it by examining eye movements in reading by Heritage Speakers (HSs) and L2 learners of Russian. The eye movements of bilingual participants are compared to two control groups, monolingual adults and monolingual children. Following the introductory Chapter 1, in Chapter 2 we present the study that establishes basic eye-movement characteristics in reading for Heritage Speakers and L2 learners in connection to proficiency and linguistics factors of word length and frequency. Contrary to our predictions, we found that all eye-movement characteristics of high-proficiency HSs are different from …
The Effects Of Self-Esteem And Motivation On Cognitive Control, Andrea Benavides
The Effects Of Self-Esteem And Motivation On Cognitive Control, Andrea Benavides
Dissertations, Theses, and Capstone Projects
Cognitive control describes a set of mechanisms that guide behavior towards a goal (Cohen, 2017). The successful execution of cognitive control is essential for effective learning, information processing, problem solving, and academic achievement (Visu-Petra et al., 2011). The Expected Value of Control framework (EVC; Shenhav et al., 2013) suggests that control carries an inherent cost, which is weighed against the potential benefits of expending it. This cost-benefit analysis determines the direction and intensity that a goal is pursued. Importantly, motivation plays a role in this cost-benefit analysis and may function as the factor that offsets the cost of control expenditure …
Applying A Metacognitive Framework In The Neuropsychological Assessment Of Subjective Cognitive Decline And Mild Cognitive Impairment, Susan Y. Chi
Dissertations, Theses, and Capstone Projects
The characterization of the earliest stages of Alzheimer's disease (AD) is a topic of major research interest because it is critical for early diagnosis and emerging interventions. Metamemory, or knowledge about memory, including awareness of one’s own memory functions, has been investigated in AD especially in relation to how impairment in memory and executive functions contribute to unawareness of cognitive deficits, termed anosognosia. Previous research, however, has not systematically investigated metamemory functioning in older adults with prodromal dementia conditions. Therefore, we investigated metamemory accuracy in cognitively healthy older adults (HC) and those with subjective cognitive decline but intact neuropsychological test …
Beyond Exposure: Markers Of English Proficiency In School-Aged French–English Bilinguals, Erin Quirk
Beyond Exposure: Markers Of English Proficiency In School-Aged French–English Bilinguals, Erin Quirk
Dissertations, Theses, and Capstone Projects
Bilingual children show more variation in their language development than monolingual children, a fact that has been linked to their experience with their languages. Bilingual language experience also varies more than monolingual children's, both in terms of how much they hear the language spoken around them (exposure) and how much they speak the language themselves (production). This dissertation investigates the following aspects of the relationship between bilinguals’ language experience and development which are not well-understood: how children’s language production relates to their proficiency in that language, how children’s language exposure relates to receptive versus expressive and lexical versus grammatical skill, …
