Studies indicate that young only children are more likely than those with siblings to have egocentric tendencies. Egocentrism is a maladaptive behavior from a lack of Theory of Mind understanding, which is the ability to take on the perspectives of others and to discern emotional cues. The current study determines whether or not only children are more likely respond negatively to teacher criticism. Only children (N=100) and those with siblings (N=100) aged six years were be tested on tasks measuring egocentrism, ToM understanding, and their response to teacher constructive criticism. Only children are expected to have lower ToM task scores, respond more negatively to criticism, and to be more likely to display traits of egocentrism than those with siblings. These potential results indicate that there is something developmentally beneficial in having a sibling(s), which promotes social and emotional competency in young children that is not necessarily prevalent for only children. Further research should examine children at an even younger age to determine when and how the difference in ToM understanding occurs.

A predicted association between family relations and cognitive development and the emergence of adolescent egocentrism was explored in this study. A sample of seventh grade boys (n=131) and girls (n=120) completed Elkind and Bowen's Imaginary Audience Scale (a measure of egocentrism) and selected items from Heilbrun's Parent-Child Interaction Rating Scale and Schaefer's Parent-Behavior Inventory. A modified version of Lawson's Classroom Test of Formal Operations was used to measure cognitive development. Contrary to a theoretical based hypothesis a negative rather than positive relationship was found between level of formal operational thought egocentrism. For parenting style, perceived rejection/control and emotional support was associated with diminished egocentrism. Mixed results were found for perceived physical effect and egocentrism. Perceived parental withdrawal heightened egocentrism for both sexes. The data provide an alternative model to past cognitive development theory for the development of egocentrism. Parental socialization factors were found to contribute as much variance to the level of egocentrism as did level of formal operational thought.

Adolescence is often seen as a stage where risk taking and experimentation are common. The need to feel a part of one’s peer group, to be valued as an individual and to overcome physical and emotional changes are all part of this developmental stage. This research examines the link between Elkind’s theory of Egocentrism and risk taking in female adolescents. Risk taking and its links to the Personal Fable and the Imaginary Audience were the main focus of the research. This study used a qualitative research design to obtain an in-depth understanding of risk taking among a sample group of ten female adolescents. A focus group from a different school was used to help analyse and discuss the data obtained. The results of this study show that Elkind’s theory of adolescent Egocentrism (both the Personal Fable and the Imaginary Audience) are, indeed, influencing factors in female adolescent risk taking.

TAMCHYNA, M. Personality Depravation in Forensic Psychology. Dissertation. Charles University in Prague, Faculty of Arts, Department of Psychology Advisor - PhDr. Miluše Urbanová, CSc. Co-advisor - PhDr. Alena Marešová, Ph.D. Abstract: The dissertation addresses the issue of negative personality changes understood as personality depravation. The introduction discusses their increase in normally socialized (non- criminal) population and states the need for a solution of this problem. The term depravation, which is taken from clinical practice, is analyzed from a theoretical perspective in the first part of this work. This research also builds upon empirical surveys of personality of groups of juvenile and adult convicts and non-delinquent control groups, which are described in the second part. Long- term empirical surveys repeated every decade (1979 - 2013) focus on personality depravation and are based on comparative analysis of standardized and quantified data - sociodemographic data, analyses of criminal activity, personality assessments using a standardized inventory of tests designed to ascertain personality depravation, and case histories of delinquents (n=1660). Generalizations of the findings are used to capture trends of personality change in convicts. The third part of this work describes the...

Thesis (M.Ed.)--University of the Witwatersrand, Faculty of Education, 1999. / In opposition to the historically accepted view that Piaget failed to theorise the ‘social’ in his theory of cognitive development this research report shows that the ‘social’ is central to his genetic epistemology and that his conceptualisation of the ‘social’ has interesting implications for educational thinking. Specifically, the report shows that not only did Piaget include the social dimension in his genetic epistemology but that his understanding of the role of the ‘social’ in the development of cognition raises interesting possibilities for future psychological and educational research.

Beeinflusst unsere Variabilität, wie wir über andere denken? Betrifft die Veränderung unserer Persönlichkeitszustände mehr als uns selbst? Wie beeinflussen andere unsere Persönlichkeitsentwicklung? Wie wirkt sich Selbstbezug auf das Denken über andere aus? In dieser Arbeit werden die vielfältigen Beziehungen zwischen unserer Persönlichkeit und der Beziehung zu und Interaktion mit anderen Menschen in verschiedenen Bereichen der Persönlichkeitspsychologie untersucht. Neben der Zusammenfassung der vier Veröffentlichungen, wird der theoriegeleitete Ansatz erläutert und in Persönlichkeitsdynamik und -prozesse eingeführt. Zentral sind die Konzepte der Persönlichkeitsmerkmale, der innerpersonellen Variabilität, der Persönlichkeitsentwicklung, des Selbstfokus, des Egozentrismus und der egozentrischen Verzerrung–im Rahmen ihrer Bedeutung für die Theory of Mind (ToM). Publikation 1 schlägt ein zweistufiges Model vor, wie die innerpersonelle Variabilität die ToM durch Erweiterung und Relativierung des Egozentrismus einer Person erleichtern kann. Publikation 2 fürht die Terminologie und die statistischen Werkzeuge der dynamischen Systemtheorie für die Untersuchung von Persönlichkeitszuständen ein und diskutiert Anwendungsfälle. Publikation 3 stellt ein Klassifizierungssystem vor, mit dem systematisch zwischen persönlichen und kollektiven Lebensereignissen unterschieden werden kann, wobei die unterschiedlichen Mechanismen berücksichtigt werden, durch die beide Arten von Lebensereignissen die Persönlichkeitsentwicklung beeinflussen können. Publikation 4 präsentiert Belege für eine kleine, aber robuste positive Beziehung zwischen achtsamer Selbstfokussierung und ToM. Nach der Reflektion der Beiträge zum Fachgebiet werden drei Forschungsansätze aus dem Risikomanagement, der Persönlichkeitspsychologie und den Neurowissenschaften diskutiert, die auf die Forschung zu innerpersönlicher Variabilität und Persönlichkeitsentwicklung sowie zu Egozentrismus und ToM einzahlen könnten. / Does our own variability affect how we think about others? Do personality states changes involve more than ourselves? How do others affect our personality development? How does focusing on oneself affect thinking about others? This dissertation explores the many relationships between an individual’s personality and ther relation to and interaction with other people across multiple areas of personality psychological research. Before summarizing four publications of this cumulative project, I explain my theory-driven approach and introduce the field of personality dynamics and processes. In particular, I focus on the concepts of personality traits, within-person variability, personality development, self-focus, egocentrism, egocentric bias–often in light of their relevant for Theory of Mind. The first publication proposes a two-tier framework of how within-person variability can facilitate Theory of Mind by broadening and relativizing a person’s egocentrism. The second publication introduces the terminology and statistical tools of dynamic systems theory to the investigation of personality state levels and presents possible use cases. The third publication introduces a classification system to differentiate between personal and collective live events in a systematic way that is sensitive to the different mechanisms by which both kinds of life events can affect personality development. The fourth publication presents evidence for a small but robust positive relationship between mindful self-focus and Theory of Mind. Finally, I reflect on the publications’ contributions to the field and suggest three lines of research stemming from risk management, personality psychology, and neuroscience that could inform research on within-person variability and personality development as well as on egocentrism and Theory of Mind further in the future.
