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 …
Language Experience: The Perception Of Foreign Language Acquisition Among University Adults, Lileth A. Stricklin
Language Experience: The Perception Of Foreign Language Acquisition Among University Adults, Lileth A. Stricklin
Honors Theses
While bilingualism has always existed within the history of the U.S. and is the global norm, mainstream approaches to learning have traditionally been monolingually centered and fail to employ approaches that produce sustainable motivation towards foreign language acquisition in students. This study sought to investigate the perceptions adult individuals display towards acquiring foreign language skills, emphasizing distinctions exhibited between monolinguals and their multilingual counterparts. A mixed-method approach in the analysis of 506 survey responses yielded results that suggest that university adults generally display positive perceptions towards foreign language learning. Distinctions in perception between monolinguals and multilinguals were very few with …
Does Optic Flow Provide Information About Actions?, Hannah Masoner
Does Optic Flow Provide Information About Actions?, Hannah Masoner
Dissertations
Optic flow, the pattern of light generated in the visual field by motion of objects and the observer’s body, serves as information that underwrites perception of events, actions and affordances. This visual pattern informs the observer about their own actions in relation to their surroundings, as well as those of others. This study explored the limits of action detection for others as well as the role of optic flow. First-person videos were created using camera recordings of the actor’s perspective as they performed various movements (jumping jacks, jumping, squatting, sitting, etc.). In three experiments participants attempted to detect the action …

How Well Do You Know Your Reach?, Tyler Surber
How Well Do You Know Your Reach?, Tyler Surber
Dissertations
How does the relationship between an actor’s body proportions (eye-, shoulder-, and arm length) and environmental properties (object distance) affect the perception of whether an object is within reach? Experiment 1 demonstrated that participants are more accurate at judging their own eye height than shoulder height. Experiment 2 revealed that participants can accurately perceive the angular direction to a target object’s location. Interestingly, their pointing errors were significantly smaller when measured from the shoulder as a reference point than from the eye. In Experiment 3 we verified this finding using a functionally meaningful affordance task of reaching to a target …
The Role Of Action In Affordance Perception Using Virtual Reality, Ashley J. Funkhouser
The Role Of Action In Affordance Perception Using Virtual Reality, Ashley J. Funkhouser
Honors Theses
Space perception in virtual reality (VR) is distorted. Does action in conjunction with an avatar's presence improve perception in VR? Participants judged whether a virtual ball was within reach. Condition 1 was perception-only, where the participant was not allowed to move nor could see their arms. Condition 2 was perception with nonvisible action, where the participant could move their real arm to reach but could not see an avatar representation of the arm. Condition 3 was perception with visible action, where the participant could move and see a virtual hand that corresponded to the actual arm movement. Participants overestimated their …
Correspondence Between Haptic And Visual Perception Of Stand-On-Ability: Do Hills Look As Steep As They Feel?, Jonathan Kenealy Doyon
Correspondence Between Haptic And Visual Perception Of Stand-On-Ability: Do Hills Look As Steep As They Feel?, Jonathan Kenealy Doyon
Master's Theses
Vision and haptics play a central role in perceiving environmental layout to guide action. Hajnal, Wagman, Doyon, and Clark (2016) demonstrated that visual perception of stand-on-ability is accurate compared to action capabilities, whereas haptic perception of stand-on-ability reliably underestimates action capabilities. This finding contradicts Gibson’s (1979) theory of equivalence in perceptual systems, which suggests that perception should be equivalent regardless of modality. Previous comparisons of visual and haptic perception tested the modalities in isolation. The current experiment directly compares visual to haptic perception of stand-on-ability by using one perceptual system to estimate the other. Observers viewed a surface set to …
Form-Blindness And Its Implications: A Verification Study, Meredith G. Moody
Form-Blindness And Its Implications: A Verification Study, Meredith G. Moody
Honors Theses
Form-blindness is not an eye problem. It is a perceptual inability to distinguish the small differences between shapes, colors, and patterns. This research examines this phenomenon by using a previously-established exam to study form-blindness and its implications. Demographic variables such as age, major, GPA, and sex are also looked at to see what potential impact they might have on a person’s performance on the exam. The form-blindness tests administered during this study were graded and then analyzed using descriptive statistics and multiple linear regression. In the end, no statistical significance was found for the demographic variables of age, GPA, major, …
The Perception Of Distance On A Real Geographic Slope, David Alan Bunch
The Perception Of Distance On A Real Geographic Slope, David Alan Bunch
Dissertations
Ooi, Wu, and He (2001) have shown that for objects resting on flat, horizontal surfaces, those that appear in the lower sector of the visual field are perceived as close to the observer and objects located near the visual horizon are perceived as further from the observer. Researchers have hypothesized that observers utilize the angle subtended between the horizon and the line of sight to the target object as information for distance.In a previous investigation Hajnal, Bunch, and Kelty-Stephen (2014) showed that an object’s physical angle of declination below the horizon is not uniquely utilized when making distance estimates to …
Ecological Psychology And Media Consumption Among Young Adults: A New Framework, Alice Diana Cade Ferguson
Ecological Psychology And Media Consumption Among Young Adults: A New Framework, Alice Diana Cade Ferguson
Dissertations
The Pew Research Center (2010, March 1) identified three crucial “new metrics of news” (p. 2) that help to explain the appeal of new, interactive media forms among young adult news consumers. These metrics of Portability, Personalizability and Participation (Pew, 2010) highlight the rapid transformations in technology and user interests that have helped create a new manifestation of what McLuhan called an “age of anxiety” (1967/2001, pp. 8-9) in mass media industries and in mass communication education and scholarship. The purpose of this research is to investigate this very shift in how news is delivered and consumed, with particular attention …
