The Ontogeny Of Whistle Production In Infant Atlantic Bottlenose Dolphins (Tursiops Truncatus) During The First Thirty Days Of Life, Brittany Leigh Jones
The Ontogeny Of Whistle Production In Infant Atlantic Bottlenose Dolphins (Tursiops Truncatus) During The First Thirty Days Of Life, Brittany Leigh Jones
Master's Theses
The manner in which dolphin calves acquire their whistle repertoire is largely unknown. This paper focuses on whistle development in four bottlenose dolphin calves during the first thirty days of life in order to increase our understanding of the early emergence of whistles and whistle-like vocalizations. The acoustic parameters of whistle-type vocalizations (i.e., whistles and whistlesquawks) that coincided with a bubblestream emission from the focal calf and/or its mother were analyzed, as were the behavioral states of the mother-calf pair during the emission of such vocals. Mother and calf whistle rates are inversely related, with the mother whistling more often …
The Effect Of Local Element Density On Processing Of Visual Hierarchical Patterns: An Infant Erp Study, Sara M. Mosteller
The Effect Of Local Element Density On Processing Of Visual Hierarchical Patterns: An Infant Erp Study, Sara M. Mosteller
Masters Theses
Previous research with infants, children, and adults has shown that global, or configural, information is processed before local, or featural, information in high density visual hierarchical patterns (Freeseman, Colombo, & Coldren, 1993; Ghim & Eimas, 1988; Kimchi, 1988; Navon, 1981; Navon, 1977). The current study used event-related potential to determine if a well documented bias toward global processing in infancy can be disrupted when the number and density of local elements is reduced through increasing the distance between elements. Infant responses were compared between high and low density conditions to global and local novel patterns and to familiar patterns. A …

The Effects Of Arousal Induction On Infants' Tempo Preferences, Erin G. Eisen
The Effects Of Arousal Induction On Infants' Tempo Preferences, Erin G. Eisen
Undergraduate Honours Theses
Previous research has demonstrated that infants have a natural preference to listen to fast temporal sequences over intermediate temporal sequences (Steffler, 2012, unpublished thesis). The present study seeks to explore whether or not infant tempo preferences are context-dependent, specifically examining the effect of arousal levels on tempo preferences. In the current study, 6- to 8-month-old infants' preference for tempo was evaluated using a head-turn preference procedure, following an arousal induction phase, in which the infants' environment was altered with the aim of lowering their physiological arousal. Infants showed a significant 3-way interaction between side of presentation, first stimulus presentation, and …
