Audio Narration And Reading Ability In Programmed Instruction, Wendy Jaehnig
Dissertations
This study compared the effects of audio, textual, and audio-textual narration in a programmed instructional module on the performance of individuals with different reading abilities. One hundred eighty-four college students were randomly assigned to audio, textual, or audio-narration. Dependent variables were posttest score and instruction completion time. An ANCOVA was used to analyze the results, with ACT reading test scores as the covariate. No differences were found between the groups on posttest scores (p = .56) or completion time (p = .90), and there was no interaction between narration type and reading score for either dependent variable. Audio …

Investigating The Effects Of Real-Time Visual Feedback On Computer Workstation Posture, Sigurdur Oli Sigurdsson
Dissertations
The purpose of this study was to examine the effects of a package intervention that included discrimination training, real-time visual feedback, and self-monitoring on postural behavior at a computer workstation in a simulated office environment. A total of 21 participants were screened for participation, and eight of those participated throughout the study. A non-concurrent multiple baseline design across participants was used to assess the effects of the interventions across three postural variables. Following an information-only phase, participants were exposed to the intervention for the lowest stable postural variable. For most targeted postural variables, the intervention implemented in this study led …
