Anterior And Posterior Types Of Neuropsychological Deficits In Parkinson’S Disease: A Subgroup Classification Of Cognitive Outcome, Megan M. Risi
Anterior And Posterior Types Of Neuropsychological Deficits In Parkinson’S Disease: A Subgroup Classification Of Cognitive Outcome, Megan M. Risi
Honors Program Theses and Projects
Individuals with Parkinson’s disease (PD) exhibit cognitive deficits. Recent studies suggest there are distinct cognitive profiles of PD characterized by deficits in abilities that are dependent upon anterior versus posterior areas of the brain. While anterior-based deficits are more prevalent, posterior-based deficits are more predictive of the future occurrence of dementia in PD. The purpose of the current project was to examine these cognitive profiles in more detail. Performance on six tests of anterior function and six tests of posterior function was examined in 34 non-demented PD participants and 27 healthy control participants matched for age and education. Results showed …
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 …
The Influence Of Spatial Distance Priming On Test Anxiety And Judgments, Eric R Raap
The Influence Of Spatial Distance Priming On Test Anxiety And Judgments, Eric R Raap
Masters Theses & Specialist Projects
This paper examined the effects of distance priming on test anxiety and judgment. Research suggests that individuals’ perceived distance can impact their affect and judgments, which sheds light on the principle of “distance equals safety” (Williams & Bargh, 2008). Taking an exam invokes both cognitive and emotional anxiety, such as worry, panic, and tension. It is hypothesized that the distance priming may reduce test anxiety—particularly, the emotionality aspect—as well as perceived test difficulty. The results showed that, counter to the hypotheses, there was no significant difference among the three priming groups in their emotional test anxiety or perceived test difficulty. …
The Influence Of Children's Affective Ties On The Goal Clarification Step Of Social Information Processing, Amanda C. Thorn
The Influence Of Children's Affective Ties On The Goal Clarification Step Of Social Information Processing, Amanda C. Thorn
Masters Theses & Specialist Projects
Previous studies have shown that children’s social goals are influenced by
emotion and that emotions can be manipulated using relationships. The present study combines these previous findings by examining the effect of children’s relationships on social goals. Social goals were examined in second and fifth grade children using hypothetical ambiguous provocation situations in which the relationship between the participant and the provocateur was manipulated by inserting the name of a friend, enemy, or a neutral peer into the story. After each situation, children rated the importance of four different social goals, indicating which of the four would be the most …
Intrinsic And Extrinsic Motivation: Abraham Lincoln As An Adult Learner, Warren Greer
Intrinsic And Extrinsic Motivation: Abraham Lincoln As An Adult Learner, Warren Greer
Masters Theses & Specialist Projects
Over the last two decades, research has identified factors that foster versus undermine human motivation and well being with important implications for learning and performance. Much of the research is concerned with intrinsic versus extrinsic motivation and autonomous versus non-autonomous learning environments. The data suggests that learning and performance are often significantly enhanced in autonomy-supportive environments that foster intrinsic motivational perspectives. This study examines the lived experience of Abraham Lincoln in the context of his adult learning motivation, forming a qualitative narrative around his adult educational experiences. It was hypothesized that Abraham Lincoln benefited from learning experiences with high levels …
Ages Of Engagement In Risk Taking And Self-Harm: An Investigation Of The Dual Systems Model Of Adolescent Risk Taking, Brittany Dykstra
Ages Of Engagement In Risk Taking And Self-Harm: An Investigation Of The Dual Systems Model Of Adolescent Risk Taking, Brittany Dykstra
Masters Theses & Specialist Projects
Risk taking (RT) and self-harm (SH) are clinically, conceptually, and empirically
related, yet separate constructs, which occur most frequently during adolescence. The current study utilized retrospective reports of college students to determine reported ages of engagement in RT and SH behaviors. Reported ages were compared with predictions for ages of high frequency engagement in RT based on the Dual Systems Model of Adolescent Risk Taking (DSMART; Steinberg, 2010). The sample consisted of 228 college students, ranging in age from 18 to 48 years (mean 22.8), who completed a survey of commonly investigated RT (12 items) and SH (18 items) behaviors. …
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 …
Dot Polarity In Dynamic Glass Patterns, Dawn Vreven, Timothy Petersik, Jim Dannemiller, Jamie Schrauth
Dot Polarity In Dynamic Glass Patterns, Dawn Vreven, Timothy Petersik, Jim Dannemiller, Jamie Schrauth
Dawn L Vreven
Each frame of a Glass pattern consists of a random placement of dots and a spatially shifted copy of this pattern. Thus, each dot has a partner, forming dot-pair dipoles. When shown in succession, motion is perceived along the axis of the spatial shift. The perception of motion in dynamic Glass patterns is believed to be a two-stage process: first, local orientation detectors respond to the orientation signal in the dot-pair dipole; and second, global detectors integrate local orientation signals. We examined the ability to detect rotation in dynamic Glass patterns whose dipoles contained a) the same polarity, b) opposite …
Integration Of Speed Signals In The Direction Of Motion, Dawn Vreven, Preeti Verghese
Integration Of Speed Signals In The Direction Of Motion, Dawn Vreven, Preeti Verghese
Dawn L Vreven
Speed discrimination tasks were used to examine the spatial and temporal characteristics of the integration mechanism involved when signals are extended in the direction of motion. We varied the aspect ratio of a signal patch whose speed differed from the background, while holding the area of the signal patch constant, so that the signal patch could be either extended in the direction of motion or extended orthogonal to the direction of motion. Speed discrimination thresholds decreased dramatically as the signal patch was extended in the direction of motion. The spatial and temporal integration regions were larger than would be expected …
Music And Movement Share A Dynamic Structure That Supports Universal Expressions Of Emotion, Beau Sievers, Larry Polansky, Michael Casey, Thalia Wheatley
Music And Movement Share A Dynamic Structure That Supports Universal Expressions Of Emotion, Beau Sievers, Larry Polansky, Michael Casey, Thalia Wheatley
Dartmouth Scholarship
Music moves us. Its kinetic power is the foundation of human behaviors as diverse as dance, romance, lullabies, and the military march. Despite its significance, the music-movement relationship is poorly understood. We present an empirical method for testing whether music and movement share a common structure that affords equivalent and universal emotional expressions. Our method uses a computer program that can generate matching examples of music and movement from a single set of features: rate, jitter (regularity of rate), direction, step size, and dissonance/visual spikiness. We applied our method in two experiments, one in the United States and another in …
