The Effect Of Environmental Context Upon Visual Distance Perception, Jessica M. Dukes Apr 2021

The Effect Of Environmental Context Upon Visual Distance Perception, Jessica M. Dukes

Masters Theses & Specialist Projects

The ability of 16 younger adults to visually perceive distances in depth was evaluated within three environmental contexts (indoors in the dark, indoors in the light, and outdoors). The observers' task was to bisect an 8m distance interval in all contexts using both monocular and binocular vision. In the outdoor environment (a natural grassy field), the observers' judgments indicated perceptual compression of farther distances similar to that obtained in many previous studies. In the indoor lighted environment (a 10.2 x 9.6m laboratory room), the observers' judgments were consistent with perceptual expansion of farther distances. Finally, there was a beneficial effect …

Aging And Visual Spatial Integration, Alexia J. Higginbotham

Masters Theses & Specialist Projects

The current study evaluated the ability of 20 younger and 20 older adults to discriminate shapes depicted by Glass patterns. On any given trial, observers identified a particular pattern as either possessing a radial or concentric organization. Detecting a shape defined by a Glass pattern requires the successful detection of the orientations of its constituent local dipoles. In addition, long-range processes are needed to integrate the spatially separated dipoles into perceivable contours that have a particular (e.g., radial or concentric) organization. In the current experiment, the shapes were defined by either 40 or 200 oriented dipoles spread over an area …


Beauty In Snowflakes: Complexity And Visual Aesthetics, Olivia C. Adkins Apr 2016

Beauty In Snowflakes: Complexity And Visual Aesthetics, Olivia C. Adkins

Masters Theses & Specialist Projects

Experimental aesthetics research has been conducted since the nineteenth century. Interestingly, however, few studies have examined the perceived beauty of naturally shaped objects. In the current experiment, 204 participants were presented with a set of ten snowflake silhouettes that varied in complexity (perimeter relative to area); they were similarly presented with ten randomly-shaped, computer-generated, solid objects that also varied in complexity. For each stimulus set, the participants selected the single snowflake or object that was the most beautiful (Fechner’s method of choice). The results for the solid objects replicated the findings of earlier research: the most and least complex objects …
