The Effect Of Age-Related Declines In Inhibitory Control On Audiovisual Speech Intelligibility, Avanti Dey
The Effect Of Age-Related Declines In Inhibitory Control On Audiovisual Speech Intelligibility, Avanti Dey
All Theses and Dissertations (ETDs)
Audiovisual: AV) speech perception is perception in which both auditory and visual information is available in order to understand a talker, compared to an auditory signal alone, during face-to-face communication. This form of communication yields significantly higher word recognition performance as compared to either sensory modality alone, constituting a general AV advantage for speech perception. Despite an overall AV advantage, older adults seem to receive less benefit from this bimodal presentation than do younger adults. However, there is evidence to suggest that not all age-related deficits in AV speech perception are of a sensory nature, but are also influenced by …
The Process Dissociation Of Moral Judgments: Clarifying The Psychology Of Deontology And Utilitarianism, Paul Conway
The Process Dissociation Of Moral Judgments: Clarifying The Psychology Of Deontology And Utilitarianism, Paul Conway
Electronic Thesis and Dissertation Repository
A growing body of work has examined responses to moral dilemmas where causing some degree of harm leads to a greater positive outcome; such dilemmas are said to pit deontological philosophical considerations (causing harm is never acceptable) against utilitarian philosophical considerations (causing harm is acceptable if it leads to the best possible outcome). According to dual-process theories of moral judgment, independent processes drive each judgment: affective reactions to harm drive deontological judgments, whereas cognitive evaluations of outcomes drive utilitarian judgments. Yet, theoretically both processes contribute to each judgment; therefore, it is an error to equate judgments with processes. To overcome …
The Role Of Cognition In Oral & Written Transmission As Demonstrated In Ritual Chant, Mary Elizabeth Husslein
The Role Of Cognition In Oral & Written Transmission As Demonstrated In Ritual Chant, Mary Elizabeth Husslein
Theses and Dissertations
This thesis examines the role of cognition in oral and written transmission. It looks at areas of music history where cognition is already used as a reference, including the development of notation, trends and changes in oral transmission, and performance practice. The thesis examines three different case studies on ritual chant in order to demonstrate how the cognitive process can be used to explain the ways learning, retention, and transmission work in oral and written transmission. The first case study is on the chant practices originating in Jerusalem. It discusses the intervallic relationships and music patterns involved in retention of …
Validation Of The Adapted Cogstate Brief Battery In Hematopoietic Cell Transplant Patients, Bethany Gourley
Validation Of The Adapted Cogstate Brief Battery In Hematopoietic Cell Transplant Patients, Bethany Gourley
Master's Theses and Doctoral Dissertations
A small literature has documented cognitive deficits in adult hematopoietic cell transplant (HCT) survivors across the transplant trajectory, primarily occurring in memory, executive function, attention, and processing speed. Although HCT-associated cognitive decline occurring within one year of transplantation is well documented, only two studies have longitudinally investigated cognitive function in HCT survivors beyond one year. Furthermore, studies demonstrating neuropsychological decline have made use of numerous measures and varying impairment criteria, making the compilation of findings across studies challenging. Another difficulty with the current literature base is the use of traditional neuropsychological tests that are susceptible to practice effects and thus …
Visual Attention Bias And Body Dissatisfaction In Eating Disorders, Janet Lydecker
Visual Attention Bias And Body Dissatisfaction In Eating Disorders, Janet Lydecker
Theses and Dissertations
Eating disorders, such as anorexia and bulimia nervosa, have profound negative effects on the quality of life of both affected individuals and their families. Behavioral approaches such as cognitive-behavioral therapy (CBT) are commonly used for the treatment of these disorders. CBT teaches skills to restructure maladaptive thought patterns as a method of altering feelings and behaviors. However, even after CBT, 50-70% of women with bulimia and 67-87% of women with anorexia report continued eating disordered thoughts, feelings and behaviors. Measuring underlying cognitive processes such as orienting, maintaining, and executive attention in individuals with eating disorder symptomatology might be an important …
Diffusion Tensor Imaging And Neuropsychological Performance In Insulin Resistant Individuals, Elizabeth M. Lane
Diffusion Tensor Imaging And Neuropsychological Performance In Insulin Resistant Individuals, Elizabeth M. Lane
Dissertations
The current study sought to understand relationships between insulin resistance (IR), diffusion tensor imaging (DTI), and cognitive performance. It was hypothesized that IR would have a negative impact upon white matter and cognition. It was predicted that the uncinate fasciculus would be the most severely impacted, and this in turn would affect executive function and memory. Aim: The purpose of the study was to determine the impact of IR on white matter brain integrity among cognitively normal older adults using DTI and neuropsychological test performance. Background: The prevalence of IR has increased with growing incidence of obesity and older aged …
The Effects Of Progesterone Receptor On Development Of Serotonergic Circuits That Mediate Cognition, Heather Smith
The Effects Of Progesterone Receptor On Development Of Serotonergic Circuits That Mediate Cognition, Heather Smith
Psychology
As the rate of premature births has been substantially increasing, progestin administration is becoming a common treatment for the prevention of preterm labor. However, not much is known regarding how these hormonal supplements may affect the development of the fetal brain. The developing brain is highly sensitive to progesterone as progesterone receptor (PR) is expressed in many regions during critical developmental periods. Steroid hormone receptors such as PR are powerful transcription factors and regulate gene expression to alter fundamental processes of neural development. During the developmental period of post-natal day one (P1) to P14 in rats, PR is transiently expressed …
Relations Among Type 2 Diabetes, Arterial Stiffness And Cognitive Functioning, Gregory A. Dore
Relations Among Type 2 Diabetes, Arterial Stiffness And Cognitive Functioning, Gregory A. Dore
Electronic Theses and Dissertations
Although the associations among diabetes mellitus, cognitive functioning and arterial stiffness have been explored previously, the degree to which arterial stiffness is responsible for the association between diabetes and cognitive function has not been examined. The primary aim of the current investigations is to examine the extent to which arterial stiffness mediates the association between diabetes and cognitive function, as well as the extent to which this indirect effect is modified by age and APOE genotype. The sample included 590 participants (age 23-94, 62% women, 12% African- American) from the seventh wave of the Maine-Syracuse Longitudinal Study. Individuals with history …
Infants’ Responses To Affect In Music And Speech, Daniel K. Feinberg
Infants’ Responses To Affect In Music And Speech, Daniel K. Feinberg
Pitzer Senior Theses
Existing literature demonstrates that infants can discriminate between categories of infant-directed (ID) speech based on the speaker’s intended message – that is, infants recognize the difference between comforting and approving ID speech, and treat different utterances from within these two categories similarly. Furthermore, the literature also demonstrates that infants understand many aspects of music and can discriminate between happy and sad music. Building on these findings, the present study investigated whether exposure to happy or sad piano music would systematically affect infants’ preferences for comforting or approving ID speech. Five- to nine-month-old infants’ preferences for comforting or approving ID speech …
The Effect Of Oral Contraceptives On Performance In Sexually Dimorphic Cognitive Tasks, Kathryn Sears
The Effect Of Oral Contraceptives On Performance In Sexually Dimorphic Cognitive Tasks, Kathryn Sears
Honors Theses
The goal of the current study was to further extend limited research assessing the effects of sex, menstrual phase, and oral contraceptive use on sexually dimorphic cognitive tasks, as well as emotional regulation. Studies have found that menstrual cycle phases have cognitive and physiological effects on women’s brains depending on the concentration of female sex hormones, progesterone and estrogen (Epting & Overman, 1998). Oral Contraceptive pills (OC) contain a concentration of these female sex hormones that have been shown to alter gray matter volume to resemble men’s brains in areas associated with learning, memory, spatial navigation, and emotional regulation (Pletzer …
Antidepressant Medications And Cognitive Functioning In Major Depressive Disorder, Rachel Kay
Antidepressant Medications And Cognitive Functioning In Major Depressive Disorder, Rachel Kay
Wayne State University Theses
Individuals with Major Depressive Disorder (MDD) frequently experience cognitive decrements in addition to mood impairments. Ironically, antidepressant medications used to treat depression may have adverse effects on cognitive functioning. It is imperative to understand the relative cognitive costs of antidepressants when considering the treatment of MDD patients. Furthermore, observational studies of depression are challenged by problems of systematically confounded variables. Researchers are often faced with difficulties in managing this issue and opt to either ignore the problem, alter their sample, or use inappropriate statistical methods (e.g., Analysis of Covariance) due to a limited understanding of acceptable solutions. It is important …
Source Memory And Generation Effects In Parkinson's Disease, Lynn Elizabeth Oelke
Source Memory And Generation Effects In Parkinson's Disease, Lynn Elizabeth Oelke
USF Tampa Graduate Theses and Dissertations
The primary aim of this study was to investigate source memory performance in individuals diagnosed with Parkinson's disease (PD). The secondary goal was to explore how memory was impacted when subjects were asked to generate responses during encoding. Fifty idiopathic PD patients and fifty healthy control subjects completed a task measuring item memory and source memory which also included a generation manipulation. Relative to controls, PD patients exhibited deficits in source memory but not item memory. Both groups demonstrated enhanced memory performance in the generative condition of the item memory task. The PD group displayed a marginally significant trend toward …
Effects Of Construal Level On The Reliance On Affect Versus Substance, Ellen O'Malley
Effects Of Construal Level On The Reliance On Affect Versus Substance, Ellen O'Malley
Legacy Theses & Dissertations (2009 - 2024)
The influence of construal level on judgment and decision-making is often seen in consumer research. However, the effect of construal level on preferences for evaluative inputs rather than final products is less explored. Two experiments were conducted to examine whether construal level affects the degree to which individuals rely on either affective or substantive information when making evaluative judgments; specifically, that abstract construals increase reliance on affective information, whereas concrete construals increase reliance on substantive information. Experiment 1 provided evidence for a relative preference for affective versus substantive information when engaged in abstract and concrete construals, respectively. Experiment 2 replicated …
Language Development Among Preschool Age Children Born Prematurely, Brittany Nicole Peters
Language Development Among Preschool Age Children Born Prematurely, Brittany Nicole Peters
Wayne State University Theses
Premature birth has been shown to be associated with various deficits in neuropsychological functioning during early childhood; however, few studies have attempted to understand the variables that contribute to variability in performance among children born prematurely. The purpose of the current study was to investigate the relationships between specific perinatal factors and language and cognitive outcome measures in a group of preschool-aged children born prematurely (N=47). As predicted, there were significant relationships between sex and specific outcome measures, with boys performing more poorly than girls; however, contrary to hypotheses, significant relationships failed to be found between outcome measures and both …
