Effects Of Prenatal And Early Postnatal Exposure To Aversive Stimuli On Fearfulness And Exploratory Behavior In Bobwhite Qauil Neonates (Colinus Virginianus), Michael Suarez
FIU Electronic Theses and Dissertations
Neophobia, the fear of novelty, is a behavioral trait found across a number of animal species, including humans. Neophobic individuals perceive novel environments and stimuli to have aversive properties, and exhibit fearful behaviors when presented with non-familiar situations. The present study examined how early life exposure to aversive novel stimuli could reduce neophobia in bobwhite quail chicks. Experiment 1 exposed chicks to a novel auditory tone previously shown to be aversive to naïve chicks (Suarez, 2012) for 24 hours immediately after hatching, then subsequently tested them in the presence of the tone within a novel maze task. Postnatally exposed chicks …
The Effect Of Prenatal Auditory Enrichment On Perceptual Narrowing In Bobwhite Quail Neonates, Briana O'Dowd
The Effect Of Prenatal Auditory Enrichment On Perceptual Narrowing In Bobwhite Quail Neonates, Briana O'Dowd
FIU Electronic Theses and Dissertations
The development of species-typical perceptual preferences has been shown to depend on a variety of socially and ecologically derived sensory stimulation during both the pre- and postnatal periods. The prominent mechanism behind the development of these seemingly innate tendencies in young organisms has been hypothesized to be a domain-general pan-sensory selectivity process referred to as perceptual narrowing, whereby regularly experienced sensory stimuli are honed in upon, while simultaneously losing the ability to effectively discriminate between atypical or unfamiliar sensory stimulation. Previous work with precocial birds has been successful in preventing the development of species-typical perceptual preferences by denying the organism …
