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 …
Effects Of Embodiment On Perceptual And Affective Responses To Infant Crying, Jennifer B. Bisson
Effects Of Embodiment On Perceptual And Affective Responses To Infant Crying, Jennifer B. Bisson
Master's Theses
Three experiments were conducted to investigate how changes in bodily states might be related to perceptions of infant vocalizations. In Study 1, participants were asked to hold a pencil between their lips, mimicking a smile, while listening to infant crying. Although there were no embodied effects for perceptual ratings, results indicated that this manipulation decreased participants’ self-reported, negative affect. In Study 2, participants were played both infant crying and birdsong while exposed to similar embodied manipulations, including activation of muscles related to approach and withdrawal behavior. There were no embodied effects for ratings of crying or for affect. Comparing Study …
Effects Of Delayed Auditory Feedback On Young Infants’ Crying, Sarah M. Sanborn
Effects Of Delayed Auditory Feedback On Young Infants’ Crying, Sarah M. Sanborn
Master's Theses
Neural control of newborn crying has typically been considered to originate primarily in the lower brain centers, although support for this assumption is limited. To address this, the present study manipulated newborn infants’ perceptual experience during a cry bout through use of delayed auditory feedback (DAF). Atypical cry productions during DAF would suggest that newborn crying is under higher levels of cortical control than previously assumed. Infants’ spontaneous crying was recorded for 2 minutes at 4 weeks of age (n=16) and again at 8 weeks of age (n=17) using an ABA design, alternating synchronous feedback with DAF. Standard repeated-measures 2 …
