Gene-Environment Interaction: Brain-Derived Neurotrophic Factor (Bdnf) As A Moderating Factor For The Effects Of Exercise And Diet On Cognitive And Mental Health: The Cache County Study On Memory In Aging, Chelsea L. Sanders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Cache County Study on Memory in Aging, funded by the National Institute on Aging, studied longitudinal changes in memory and aging over 12 years’ follow-up in a population-based sample of 5,092 older adults in semirural Cache County, UT. Among the extensive interview procedures, researchers collected information regarding the participants’ demographics, health, genetic factors, diet, physical activity, and cognitive abilities. This study has allowed researchers to investigate how genetic and modifiable lifestyle factors interact to predict health, cognitive function, and psychological wellbeing in older adults.

Diet and exercise are important lifestyle factors in maintaining cognitive health and psychological wellbeing throughout …

Concurrent Neurological And Behavioral Assessment Of Number Line Estimation Performance In Children And Adults, Joseph Michael Baker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Understanding the brain’s response to common math-learning activities may help improve math education. For example, by imaging the brains of typically developing children and adults throughout a number line estimation task, it is possible to establish a baseline of what “typical” brains do in such situations. Thus, comparisons may be made to determine the degree to which brain functioning differs between typical and atypical math learners. Moreover, by identifying methods that may increase the brain’s response to real-world math activities, it may be possible to improve the math learning process for typical and atypical learners alike.

Brain imaging devices such …

Maladaptive Schemas As A Predictor Of Residential Treatment Outcomes In Females With Eating Disorders, Jodi Leigh Cullum

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study aimed to examine the relationship between maladaptive schemas and treatment outcomes of adolescent and adult women with an eating disorder receiving residential treatment. Existing data were obtained from 67 females aged 11 to 47 years (m =18.61) that had entered residential treatment for anorexia nervosa (AN), bulimia nervosa (BN), or eating disorder not otherwise specified (EDNOS) at a Western United States residential eating disorder treatment facility. Pre- and posttreatment data were collected by the personnel at the facility on eating disorder symptomatology, mood, and core beliefs. Three hypotheses were tested: (a) that maladaptive schemas would be …

A Reliability Measurement Of The Transactional Analysis Checklist, Robert B. Kahn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of the study was to measure the reliability of a checklist created and standardized for the study. The development of the checklist, referred to in the study as the Transactional Analysis Checklist (TAC), finds its basis in Transactional Analysis theory.

The literature available pertaining to Transactional Analysis was reviewed. No literature, prior to the study, existed which directed itself specifically to the examination of an instrument that could be used during the diagnostic phase of treatment.by .Transactional Analysts. The lack of literature was a partial motivator for the study. It was suggested that informally constructed devices are being …

A Study Of The Difference In Short-Term Memory Between Seventh Grade Students Rated High And Low In The Ability To Acquire Sport Skills, Vera Jeppesen Watkins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study investigated the possibility that the short-term memory factor may be one of the variables involved in the learning of motor skills.

The subjects of the study were all of the seventh grade gym students at Logan Junior High School who were rated by their teachers as being in the upper or lower one-fourth of their class in respect to their abilities in sport skills. After a short-term memory (STM) test developed by the researcher was administered to this group, their scores were compared to determine whether there was a significant difference between the upper and lower one-fourth.

Spatial Reasoning As Related To Solving "Story Type" Problems, James R. Holder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In this study it was hypothesized that the ability to mentally solve II story type" problems, those presented in the form of sentences, is significantly related to one's spatial reasoning ability and that a weakness in this ability, when tested by the "story type" problems, could be compensated for by training in and utilization of overt "paper and pencil" manipulations.

To test the hypothesis, three measures were used. These were the DAT Verbal Reasoning test--used to control the factor of verbal reasoning, the DAT Space Relations test--used to measure spatial reasoning ability, and two forms of a test composed of …
