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 …
Exploring The Development Of Social Responses In Children With Callous And Unemotional Traits: An Examination Of The Impact Of Hypothesized Reinforcing And Aversive Stimuli, Andre Maharaj
FIU Electronic Theses and Dissertations
Callous and unemotional (CU) traits in children with conduct problems have been indicated as precursors to adult psychopathy. The analysis of the sensitivity to rewards and punishment in this population may be useful in the identification of effective behavior modification programs and particularly the delineation of ineffective punishment procedures. Scores on the Child Psychopathy Scale, Inventory of Callous and Unemotional Traits, Contingency Response Rating Scale and the Sensitivity to Reward Sensitivity to Punishment – Children Revised scale were used to evaluate 20 children, aged 7-13, recruited from FIU’s Center for Children and Families. The sample comprised 14 males and 6 …
