The Effects Of Viewpoint, Motion, And Affordance Priming On Perceptual Learning Of Feelies, Catherine Dowell
The Effects Of Viewpoint, Motion, And Affordance Priming On Perceptual Learning Of Feelies, Catherine Dowell
Dissertations
According to Gibson and Gibson (1955) perceptual learning is a process of developing the skill to differentiate previously undifferentiated but available information. The initial investigations focused on object identification, lacking a behaviorally relevant functional task. In the current study participants learned to differentiate between novel objects (feelies). To test the role of visual exploration objects were viewed from either a side or a top view and were displayed as either static pictures or rotating about a vertical axis. In Experiment 1 a simple object discrimination task was used. Perfect accuracy was achieved sooner in static conditions compared to motion conditions …
Creating Project Contrast: A Video Game Exploring Consciousness And Qualia, Pierce Papke
Creating Project Contrast: A Video Game Exploring Consciousness And Qualia, Pierce Papke
Honors Projects
Project Contrast is a video game that explores how the unique traits inherent to video games might engage reflective player responses to qualitative experience. Project Contrast does this through suspension of disbelief, avatar projection, presence, player agency in storytelling, visual perception, functional gameplay, and art. Considering the difficulty in researching qualitative experience due to its subjectivity and circular explanations, I created Project Contrast not to analyze qualia, though that was my original hope. I instead created Project Contrast as an avenue for player self-reflection and learning about qualitative experience. While video games might be just code and art on a …
Stimulus–Response Congruency Effects Depend On Quality Of Perceptual Evidence: A Diffusion Model Account, Blaine Tomkins
Stimulus–Response Congruency Effects Depend On Quality Of Perceptual Evidence: A Diffusion Model Account, Blaine Tomkins

Individuals often need to make quick decisions based on incomplete or “noisy” information. This requires the coordination of attentional, perceptual, cognitive, and behavioral mechanisms. This poses a challenge for isolating the unique effects of each subprocess from behavioral data, which reflect the summation of all subprocesses combined. Sequential sampling models offer a more detailed examination of behavioral data, enabling us to separate decisional and non-decisional processes at play in a task. Participants were required to identify briefly presented shapes while perceptual (duration, size, location) and response features (location-congruent/-incongruent/-neutral) of the task were manipulated. The diffusion model (Ratcliff, 1978) was used …
Perceiving The Poster: How Suspicion Of Motives May Impact Perceptions Of Potential Allies Engaging In Online Activism, Kathrina Z. Durante
Perceiving The Poster: How Suspicion Of Motives May Impact Perceptions Of Potential Allies Engaging In Online Activism, Kathrina Z. Durante
Honors Theses
Social media posts signaling support for various social and racial justice movements have emerged as an important aspect of social media use. However, little research has investigated how these posts and the social media users behind them are perceived by members of disadvantaged groups﹘those the messages are presumably intended to “help.” Though the post’s content and poster’s identity are likely important, the primary aim of this study is to investigate an individual difference variable in the perceiver, specifically disadvantaged group members’ Suspicion of Motives Index (SOMI) scores, which measure a general tendency to perceive White individuals’ attempts at non-prejudice to …
Examining The Effects Of Noise And Task Dependent Performance In Prosody Perception In Autistic Individuals, Zehranur Sasal
Examining The Effects Of Noise And Task Dependent Performance In Prosody Perception In Autistic Individuals, Zehranur Sasal
Theses and Dissertations (Comprehensive)
ABSTRACT
Objective: It is known that autistic individuals have enhanced abilities in pitch discrimination and tend to excel in low-level tasks requiring lower cognitive processing. On the other hand, noise is a distracting factor in many areas of life, including prosody perception. The studies presented in this thesis aimed to understand prosody perception through different levels of cognitive tasks and under the influence of speech background noise.
Methods: In total, 256 non-autistic and 39 high-functioning autistic adults participated in these studies. In the first study, participants were asked to listen to brief utterances conveying one of six universally accepted emotions …
