Reference-frames, or coordinate systems, are used to express properties and relationships of objects in the environment. While the use of reference-frames is well understood in physical sciences, how the brain uses reference-frames remains a fundamental question. The goal of this dissertation is to reach a better understanding of reference-frames in human perceptual, motor, and cognitive processing. In the first project, we study reference-frames in perception and develop a model to explain the transition from egocentric (based on the observer) to exocentric (based outside the observer) reference-frames to account for the perception of relative motion. In a second project, we focus …

Exploratory Learning Activities In The Physics Classroom: Contrasting Cases Versus A Rich Dataset., Campbell Rightmyer Bego
Electronic Theses and Dissertations
In exploratory learning, students engage in an exploration activity on a new topic prior to instruction. This inversion of the traditional tell-then-practice order has been shown to benefit learning outcomes, especially conceptual knowledge and preparation for future learning, but not always. In three studies, the current work examines whether the type of exploration activity impacts learning mechanisms and outcomes, on the topic of gravitational field in undergraduate physics classrooms. Activities using either contrasting cases (CC) or a rich dataset (RD) are compared in two instructional orders, explore-first (EF) and instruct-first (IF). Learning outcomes measured procedural knowledge, conceptual knowledge, and performance …

Wireless Sensor System For Mild Cognitive Impairment Diagnosis, Ahmed A. Almaghasilah Mr
Electronic Theses and Dissertations
Alzheimer’s disease (AD), which causes decline in the cognitive functions, is the
major lead of dementia. AD begins showing damage in memory, making patients
dependent on caregivers. Treating AD requires early diagnosis of its signs. The
initial sign of AD is mild cognitive impairment (MCI), which is the middle stage
between a healthy patient and one diagnosed with AD. The proposed sleep
monitoring system is capable of diagnosing MCI symptoms.
MCI patients are characterized with sleep fragmentation and sleep disorder. The
sleep fragmentation is defined as awakenings that interrupt the normal sleep. The
proposed system in this thesis uses force …
