Vocal Response Of Bottlenose Dolphins (Tursiops Truncatus) To A Novel Stimulus, Lindsey Johnson Jul 2019

Vocal Response Of Bottlenose Dolphins (Tursiops Truncatus) To A Novel Stimulus, Lindsey Johnson

Master's Theses

Bottlenose dolphins utilize acoustic signals as their primary mode of communication. Although some aspects of dolphin vocal behavior are well understood, less is known about vocalizations in different behavioral contexts and how these vocal behaviors may indicate habituation and sensitization. The focus of this study was to investigate how bottlenose dolphins respond vocally to a novel stimulus. Archival data from three populations of bottlenose dolphins (N = 20) living in a human-care facility were exposed to a novel apparatus (a mirror) for 10 trials, each lasting 20 minutes. Five of the trials presented the mirror covered with an opaque cloth whereas ...


Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor Aug 2018

Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor

Master's Theses

The ability for humans to communicate with another species has been an aspiration and well documented. One example is through training animals to make associations between a designated cue and conditioned response (Pryor, 1986). Two-way communication, however, in which both species can express wants/needs has been predominantly pursued with apes and dolphins. Studies conducted by Louis Herman demonstrated the capabilities of dolphins to comprehend complex semantic and syntactic commands in an artificial language system (Herman, Richards, & Wolz, 1984). Researchers working with primates have used American Sign Language, a computer keyboard system with discrete lexigrams, and a portable lexigram keyboard (Gardner & Gardner, 1969; Rumbaugh, 1977; Savage-Rumbaugh, 1986). Savage-Rumbaugh decided to take a different approach to learning after one individual demonstrated the ability to use the keyboard ...


A Description Of Vocalizations And Their Association With Mouthing Behaviors And Social Context In Bottlenose Dolphins, Tursiops Truncatus, Christina Elyse Perazio Aug 2014

A Description Of Vocalizations And Their Association With Mouthing Behaviors And Social Context In Bottlenose Dolphins, Tursiops Truncatus, Christina Elyse Perazio

Master's Theses

Dolphin communication is multimodal and incorporates physical behaviors and vocalizations. Dolphins often exchange information with conspecifics using different types of vocalizations, and these vocalizations are sometimes associated with specific behaviors. However, the relationship of vocalization type and mouthing behavior type has not been investigated. This thesis examines simultaneous acoustic and visual recordings of bottlenose dolphins (Tursiops truncatus) to determine the relationship between type of mouthing behavior and type of vocalization (whistle, whistle-squawk, chirp, moan, burst-pulse type A, burst-pulse type B, and click trains). The role of the social context of a mouthing behavior is also evaluated. Data were obtained opportunistically ...


I'M The Same Me: Communication And Renegotiation Of Identity In The Weight-Loss Surgery Experiences Of Women, Heather D. Schild Jun 2012

I'M The Same Me: Communication And Renegotiation Of Identity In The Weight-Loss Surgery Experiences Of Women, Heather D. Schild

Master's Theses

Adult obesity rates are on the rise in the United States according to the Centers for Disease Control (2009) which has led to an increase in obesity-related illnesses such as diabetes and heart disease. Weight-loss surgery (WLS) has become accepted as a "cure" for obesity by the medical community. There has been a dramatic increase in the number of obese individuals electing to undergo WLS every year; 82% of these individuals are women (AHRQ, 2007). More women may be electing to undergo these procedures than men due to the pressures women face in American culture to achieve social standards of ...


Cognitive Dissonance In Task-Orientedgroups Under Intermittent And Continuous Success, Arthur Hiram Strock Ii Jun 1965

Cognitive Dissonance In Task-Orientedgroups Under Intermittent And Continuous Success, Arthur Hiram Strock Ii

Master's Theses

In a recent study by Burke (1961), the psychological effects of participation in task-oriented groups were studied. This study incorporated selected communication networks, the wheel, circle, and the all-channel, from a number of experimental arrangements that were conceived and developed by Bavelas (1950). Burke’s eighteen five-man groups were seated at a partitioned table containing slots in a center post through which written messages could be sent. This apparatus was similar in design to the table first used and described by Leavitt (1951). The groups worked on a task that required the members to find one symbol among five that ...
