Alterations In Neurogenesis Following The Transition From Virgin To Maternal/Lactating Female, Elizabeth Amory
Alterations In Neurogenesis Following The Transition From Virgin To Maternal/Lactating Female, Elizabeth Amory
Master's Theses
The hippocampus displays hormone induced plasticity during estrus. Pregnancy, which exposes a female to a significantly longer duration of elevated estrogen and progesterone, results in even greater changes in neurons in the CA1 region of the hippocampus, with late-pregnant and lactating females displaying a significantly higher concentration of apical dendritic spines. Hippocampal astrocytes were increased in number and showed more and thicker processes in late-pregnant and lactating females. Such anatomical changes may also enhance spatial learning and memory. Changes in reproductive capacity may influence the rate at which new neurons are born, so called neurogenesis. In two experiments, neurogenesis in …
Reproductive Experience And Stress Responsiveness, Jennifer Elizabeth Wartella
Reproductive Experience And Stress Responsiveness, Jennifer Elizabeth Wartella
Master's Theses
Hormonal fluctuations and maternal behavior associated with pregnancy and postpartum care of pups induce many changes in the female rat. Circulating hormonal surges during pregnancy modify the female brain in preparation for motherhood. Past studies identify the medial preoptic area, the hypothalamus and the basal forebrain as structures dense in hormonal receptors involved in controlling reproductive behavior. The hippocampus and amygdala possess many hormonal receptors. Neurons exposed to pregnancy hormones develop new synapses and increased spine density, changes reflected in behavioral preparations, such as nest building and increased foraging, for the new pups. Following the experience of birth, pup stimulation …
Attention, Memory, And Self-Efficacy Differences Between Adhd And Aging Individuals, Douglas Lee Welsh
Attention, Memory, And Self-Efficacy Differences Between Adhd And Aging Individuals, Douglas Lee Welsh
Master's Theses
Attention and memory abilities decline with age. Although a similar pattern of attentional and memory decrement has been observed in individuals with Attention Deficit Hyperactivity Disorder (ADHD), these two populations have never been directly compared. The present study examined performance on attention, self-efficacy (SE), and memory tasks by ADHD young adults and non-ADHD younger and older adults. ADHD adults displayed lower attentional SE than both non-ADHD younger and older adults, but performed comparably to older adults on an attention task on which non-ADHD younger adults outperformed both groups. ADHD adults and older adults had lower memory SE than non-AD HD …
Egon Brunswik (1903-1955), David E. Leary
Egon Brunswik (1903-1955), David E. Leary
Psychology Faculty Publications
Austrian and American psychologist. Brunswik stood at the nexus of several philosophical and psychological traditions, created his own distinctive psychology, and died without foreseeing the influence of his· concepts and methods. Yet more than forty years after his death by suicide, certain of his ideas and techniques are still being explored and used.
Johann Friedrich Herbart, David E. Leary
Johann Friedrich Herbart, David E. Leary
Psychology Faculty Publications
German philosopher, psychologist, and educator. Herbart was among the first, early in the nineteenth century, to propose a mathematical psychology. Coming after Immanuel Kant's claim (in his Metaphysische Angangsgriinde der Naturwissenschaft [Metaphysical Foundation of Natural Science], Riga, 1786) that there could be no such discipline, this was a bold proposal. which kept alive the eighteenth-century quest for a science of psychology. Even though Herbart himself denied the possibility of an experimental psychology, and despite the fact that his own psychology (as a branch of applied metaphysics) was largely conjectural, his example inspired subsequent scholars to work toward a quantitative, experimental …
Leadership During Personal Crisis, Gill Robinson Hickman, Ann Creighton-Zollar
Leadership During Personal Crisis, Gill Robinson Hickman, Ann Creighton-Zollar
Jepson School of Leadership Studies articles, book chapters and other publications
During a seminar involving Kellogg leadership scholars and fellows, the presenters asked participants to identify areas of study that were absent from leadership research (Concepts in Leadership seminar, 1997). Participants at this session indicated that studies involving personal aspects of leadership, among others, were noticeably absent form the literature. Leadership studies students have echoed similar sentiments about the literature and curriculum. They wanted research that focused on individuals in the leadership process as people, who must live, learn, experience, and cope with all of the issues of life, while fulfilling their roles as effective leaders and followers.
Social Comparison And Influence In Groups, Donelson R. Forsyth
Social Comparison And Influence In Groups, Donelson R. Forsyth
Jepson School of Leadership Studies articles, book chapters and other publications
This chapter is a reminder of social comparison theory's foundations in group processes rather than an extension of social comparison to groups. Social comparison research and theory, by tradition, stress individualistic, psychological purposes of comparison, such as satisfying basic drives, defining and enhancing the self, and alleviating distress or anxiety; but Festinger (1954) used the theory to explain shifts in members' opinions, elevated motivation and competition among members, opinion debates, and the rejection of dissenters in groups (Allen & Wilder, 1977; Goethals & Darley, 1987; Singer, 1981; Turner, 1991; Wheeler, 1991). This chapter revisits the theory's roots in groups before …
