Neural Reuse: A Fundamental Organizational Principle Of The Brain, Michael Anderson

Brain and Mind Institute Researchers' Publications

An emerging class of theories concerning the functional structure of the brain takes the reuse of neural circuitry for various cognitive purposes to be a central organizational principle. According to these theories, it is quite common for neural circuits established for one purpose to be exapted (exploited, recycled, redeployed) during evolution or normal development, and be put to different uses, often without losing their original functions. Neural reuse theories thus differ from the usual understanding of the role of neural plasticity (which is, after all, a kind of reuse) in brain organization along the following lines: According to neural reuse, …

Stress Levels And Development: A Phenomenology Of Autistic Children And Their Parents, Tiffany R. Wiggs

Senior Honors Theses

Being a parent means taking on both the joys and struggles that come with it. When a parent discovers that his or her child has been diagnosed with autism spectrum disorder (ASD), the level of stress changes. It could be helpful to discover the severity of change that the stresses involved in parenting a child with ASD brings to the parent/child relationship and what effect this has on a child’s physical, cognitive, emotional, and spiritual development. To attempt to answer these questions, six parents were interviewed. Findings suggested that structure in daily living improves the quality of the child/parent relationship …

A Survey Of The Management And Development Of Captive African Elephant (Loxodonta Africana) Calves: Birth To Three Months Of Age, Nicole L. Kowalski, Robert H.I. Dale, Christa L. H. Mazur

Scholarship and Professional Work - LAS

We used four surveys to collect information about the birth, physical growth, and behavioral development of 12 African elephant calves born in captivity. The management of the birth process and neonatal care involved a variety of standard procedures. All of the calves were born at night, between 7PM and 7AM. The calves showed a systematic progression in behavioral and physical development, attaining developmental milestones at least a quickly as calves in situ. This study emphasized birth-related events, changes in the ways that calves used their trunks, first instances of behaviors, and interactions of the calves with other, usually adult, elephants. …

Effects Of Chlordiazepoxide On Predator Odor-Induced Reductions Of Playfulness In Juvenile Rats, Stephen M. Siviy, Courtney L. Steets, Lauren M. Debrouse

Psychology Faculty Publications

The extent to which a non-sedative dose of chlordiazepoxide (CDP) is able to modify the behavioral responses toward a predator odor was assessed in juvenile rats. Play behavior was suppressed and defensive behaviors were enhanced in the presence of a collar previously worn by a cat, when tested 24 hours later in the same context as that where the exposure occurred, and when tested in a context different than that in which the exposure occurred for up to 3 hours after exposure. CDP had no effect on the ability of cat odor to suppress play when rats were tested in …

The Role Of Racial Information In Infant Face Processing, Angela Nicole Hayden

University of Kentucky Doctoral Dissertations

The present research addressed the development of specialization in face processing in infancy by examining the roles of race and emotion. An other-race face among own-race faces draws adults’ attention to a greater degree than an own-race face among other-race faces due to the “other-race” feature in other-race faces. This feature underlies race-based differences in adults’ face processing. The current studies investigated the development of this mechanism as well as the influence that this mechanism has on emotion processing in infancy.

In Experiment 1, Caucasian 3.5- and 9- month-olds exhibited a preference for a pattern containing an Asian face among …

New Developments In Developmental Research On Social Information Processing And Antisocial Behavior, Reid G. Fontaine

Reid G. Fontaine

The Special Section on developmental research on social information processing (SIP) and antisocial behavior is here introduced. Following a brief history of SIP theory, comments on several themes—measurement and assessment, attributional and interpretational style, response evaluation and decision, and the relation between emotion and SIP—that tie together four new empirical investigations are provided. Notable contributions of these studies are highlighted.

Developmental Variation In Children's Acquisition Of Metrical Structure: How Early Treatment Of Stressless Syllables Can Inform Phonological Theory, Clifford S. Jones

Open Access Theses & Dissertations

The present study uses 26 color photos to elicit a total of 14 words conforming to a very specific pattern: a stressless syllable word-initially, followed by a stressed syllable, and at most one more stressless syllable. This was found to be a particularly difficult metrical structure for the two- and three-year old participants to produce in an adult-like manner. Based on the findings that a fairly reliable (if language-particular) order of acquisition is observable for contrasts of both place and manner of articulation, the case is made for a system of six emergent features, which may be characterized as combinable …

The Development And Long-Term Influences Of Attachments As Seen Through Attachment Theory: The Influence Of Attachment On Homosexual Males, Christian Alvarez

CMC Senior Theses

This paper seeks to explore the development of attachments in humans as seen through Bowlby's (1980) attachment theory. Components of the theory which focus on how attachments are formed and how they influence future behavior are explored. These are used to then examine how attachment theory applies to the attachment patterns seen in homosexual males.

The Role Of The Socio-Cultural And Developmental Context On Special Education, Amanda Lam

CMC Senior Theses

Existing research on inclusive education deals primarily with the effectiveness of inclusion programs and the theoretical frameworks behind their limitation. However, no extensive research has been conducted that explores the role of the socio-cultural context and the development level in determining the best way in which the educational needs of children with special needs can be met. Recognizing that the effectiveness of different special education services may depend on the socio-cultural context as well as the development level, this literature review seeks to identify the ideal method of treating children with disabilities in developed and developing countries. By assessing the …

Effects Of Early-Life Stress On 5-Ht1a Receptors In Juvenile Rhesus Monkeys Measured By Pet, Simona Spinelli, Svetlana Chefer, Richard E. Carson, Elaine Jagoda, Lixin Lang, Markus Heilig, Christina S. Barr, Stephen J. Suomi, J. Dee Higley, Elliot A. Stein

Faculty Publications

Background—Traumatic experiences in early childhood are associated with increased risk for developing mood and anxiety disorders later in life. Low serotonin1A receptor (5-HT1AR) density during development has been proposed as a trait-like characteristic leading to increased vulnerability of stress-related neuropsychiatric disorders.

Methods—To assess the relationship between early-life stress and alterations in the serotonin system during development, we used positron emission tomography (PET) to measure in vivo 5- HT1AR density and apparent dissociation constant (KD app) in the brain of juvenile rhesus monkeys exposed to the early-life stress of peer-rearing.

Results—In general, 5-HT1AR density and KD app were decreased in peer-reared …
