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 …

Dissertations

Emotion plays an important role in human beings’ daily lives. Understanding emotions and recognizing how to react to others’ feelings are fundamental to engaging in successful social interactions. Currently, emotion recognition is not only significant in human beings’ daily lives, but also a hot topic in academic research, as new techniques such as emotion recognition from speech context inspires us as to how emotions are related to the content we are uttering.

The demand and importance of emotion recognition have highly increased in many applications in recent years, such as video games, human computer interaction, cognitive computing, and affective computing. …

What Influences Dolphin Interest In Video?, Kelley Ann Winship

Dissertations

Environmental enrichment is an important component in maintaining the welfare of animals housed in human care. While a variety of enrichment types (e.g., objects, food, sound) have been utilized, a major challenge in developing enrichment is determining the enrichment potential of various techniques for individual animals. In this study, the efficacy of video clips as enrichment devices was assessed in two species of captive dolphins, exposed to video footage accompanied by sound. Videos were evenly divided into five categories, based on content, and played at underwater viewing windows across 20 sessions while the animals were housed with conspecifics. Species and …
