Vocal Response Of Bottlenose Dolphins (Tursiops Truncatus) To A Novel Stimulus, Lindsey Johnson
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 …
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 …
A Description Of Vocalizations And Their Association With Mouthing Behaviors And Social Context In Bottlenose Dolphins, Tursiops Truncatus, Christina Elyse Perazio
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 …
Cognitive Dissonance In Task-Orientedgroups Under Intermittent And Continuous Success, Arthur Hiram Strock Ii
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 was …
