An Emergent Approach To Analogical Inference, Paul Thibodeau, Stephen J. Flusberg, Jeremy J. Glick, Daniel A. Sternberg Aug 2013

An Emergent Approach To Analogical Inference, Paul Thibodeau, Stephen J. Flusberg, Jeremy J. Glick, Daniel A. Sternberg

Faculty & Staff Scholarship

In recent years, a growing number of researchers have proposed that analogy is a core component of human cognition. According to the dominant theoretical viewpoint, analogical reasoning requires a specific suite of cognitive machinery, including explicitly coded symbolic representations and a mapping or binding mechanism that operates over these representations. Here we offer an alternative approach: we find that analogical inference can emerge naturally and spontaneously from a relatively simple, error-driven learning mechanism without the need to posit any additional analogy-specific machinery. The results also parallel findings from the developmental literature on analogy, demonstrating a shift from an initial reliance …


Alternations Of Nmda And Gabab Receptor Function In Development: A Potential Animal Model Of Schizophrenia, Monica Bolton Aug 2013

Alternations Of Nmda And Gabab Receptor Function In Development: A Potential Animal Model Of Schizophrenia, Monica Bolton

UNLV Theses, Dissertations, Professional Papers, and Capstones

Schizophrenia is a debilitating mental disorder that affects up to 3% of the world population. The behavioral symptoms are categorized into positive and negative symptoms, which appear during late adolescence/early adulthood. Unfortunately, the underlying cellular and molecular mechanisms of the disease are poorly understood. Several hypotheses exist to explain mechanisms contributing to these behavioral alterations. One model proposes that a reduced function of the NMDA glutamate receptor on specific GABAergic interneurons may be responsible for deficits in schizophrenia. Post-mortem investigations provide evidence of reductions in both glutamate and GABA-related proteins in patients with schizophrenia. Further, GABAergic interneurons that are activated …


Regrouping: Organized Activity Involvement And Social Adjustment Across The Transition To High School, Amy M. Bohnert, Julie Wargo Aikins, Nicole T. Arola Jun 2013

Regrouping: Organized Activity Involvement And Social Adjustment Across The Transition To High School, Amy M. Bohnert, Julie Wargo Aikins, Nicole T. Arola

Psychology: Faculty Publications and Other Works

Although organized activities (OAs) have been established as important contexts of development, limited work has examined the role of OAs across the high school transition in buffering adolescents' social adjustment by providing opportunities for visibility and peer affiliation. The transition to high school is characterized by numerous changes and OAs may provide an important setting for establishing and maintaining peer relationships during this tumultuous time. This study included 151 8th grade U.S. students (58% male) who were assessed across the transition to high school (spring of 8th and 9th grade). Continuous involvement in academic activities across the transition and becoming …

The purpose of this six-minute message is to share, in an engaging way, some key highlights from a variety of studies on how high profile women were raised to become leaders. It will focus on what influencers (e.g., parents, siblings, and relatives) did to rear their daughters, granddaughters, nieces, etc. to become the influential women they are today.


Examining Trajectories Of Maternal Depressive Symptoms In Relation To Infant Affect Expression, Katherine Guyon-Harris Apr 2013

Examining Trajectories Of Maternal Depressive Symptoms In Relation To Infant Affect Expression, Katherine Guyon-Harris

Master's Theses and Doctoral Dissertations

Research has shown that maternal depression can have serious physical health effects on the developing fetus as well as later cognitive, behavioral, and affective problems in children. One area of clinical significance is the effect of maternal depression across time, including the differential effects of depression on early child development during the transition to motherhood. The present study explored trajectories of maternal depression from pregnancy through 2 years postpartum and their relation to infant affect expression. Data for the study were collected as part of a larger 5-panel longitudinal study on women’s transition to motherhood. The present study will use …


Infant Perceptions Of Mixed-Race Faces: An Exploration Of The Hypodescent Rule In 8.5 Month-Old Infants, Sophie Beiers Apr 2013

Infant Perceptions Of Mixed-Race Faces: An Exploration Of The Hypodescent Rule In 8.5 Month-Old Infants, Sophie Beiers

Pitzer Senior Theses

Studies have shown that adults often categorize mixed-race individuals of White and non-White descent as members of the non-White racial group, an effect said to be reminiscent of the “hypodescent” or “one-drop rule.” This effect has not yet been thoroughly studied in infants, although 9-month-old infants have been shown to be able to categorize mono-racial faces into different racial groups. In the present study, the perception of mixed-race White and Asian/Asian American faces was studied in sixteen 8.5-month-old infants. The infants were randomly assigned to two stimulus groups. The stimuli were the photographed faces of female college students who had …

Lavigne, Laura B.K. Herzing, Edwin H. Cook, Susan A. Lebailly, Karen R. Gouze, Joyce Hopkins, Fred B. Bryant Jan 2013

Gene X Environment Effects Of Serotonin Transporter, Dopamine Receptor D4, And Monoamine Oxidase A Genes With Contextual And Parenting Risk Factors On Symptoms Of Oppositional Defiant Disorder, Anxiety, And Depression In A Community Sample Of 4-Year-Old Children, John V. Lavigne, Laura B.K. Herzing, Edwin H. Cook, Susan A. Lebailly, Karen R. Gouze, Joyce Hopkins, Fred B. Bryant

Psychology: Faculty Publications and Other Works

Genetic factors can play a role in the multiple level of analyses approach to understanding the development of child psychology. The present study examined gene-environment correlations and Gene x Environment interactions for polymorphisms of three target genes, the serotonin transporter gene, the D4 dopamine reactor gene, and the monoamine oxidase A gene in relation to symptoms of anxiety, depression, and oppositional behavior. Saliva samples were collected from 175 non-Hispanic White, 4-year-old children. Psychosocial risk factors included socioeconomic status, life stress, caretaker depression, parental support, hostility, and scaffolding skills. In comparison with the short forms (s/s, s/l) of the serotonin transporter …


Working Memory Performance Across Development And Following Acute Exercise, Patrice L. Stering Jan 2013

Working Memory Performance Across Development And Following Acute Exercise, Patrice L. Stering

Masters Theses 1911 - February 2014

This thesis investigates the developmental trajectory of visuo-spatial working memory as well as the potential influence of acute exercise on working memory performance. Individuals between the ages of 6 and 25 years were randomly assigned to a 30-minute bout of exercise on an elliptical trainer or to a no-exercise control condition. Participants then performed a computerized N-back task to assess working memory. Developmental results suggest that working memory ability continues to develop into early adulthood with the exact trajectory depending on the cognitive demand of the task being assessed. No difference in working memory performance was found between the exercise …


Developmental Changes In Postural Stability During The Performance Of A Precision Manual Task, Jeffrey M. Haddad, Laura J. Claxton, Dawn Melzer, Joseph Hamill, Richard E. A. Van Emmerik Jan 2013

Developmental Changes In Postural Stability During The Performance Of A Precision Manual Task, Jeffrey M. Haddad, Laura J. Claxton, Dawn Melzer, Joseph Hamill, Richard E. A. Van Emmerik

Psychology Faculty Publications

Posture becomes integrated with other goal-directed behaviors early in infancy and continues to develop into the second decade of life. However, the developmental time course over which posture is stabilized relative to the base of support during a dynamic manual precision task has not been examined. Postural-manual integration was assessed in 7-year-olds, 10-year-olds, and adults using a postural-manual task in which task precision (target fitting size) and postural difficulty (reaching distance to a target) were manipulated. The main dependent variable was postural time-to-contact (TtC). Results indicated systematic age effects in which TtC was shortest in the 7-year-olds, increased in the …


Patterns Of Physical And Psychological Development In Future Teenage Mothers, Daniel Nettle, Thomas E. Dickins, David A. Coall, Paul De Monrnay Davis Jan 2013

Patterns Of Physical And Psychological Development In Future Teenage Mothers, Daniel Nettle, Thomas E. Dickins, David A. Coall, Paul De Monrnay Davis

Research outputs 2013

Background and objectives: Teenage childbearing may have childhood origins and can be viewed as the outcome of a coherent reproductive strategy associated with early environmental conditions. Life-history theory would predict that where futures are uncertain fitness can be maximized through diverting effort from somatic development into reproduction. Even before the childbearing years, future teenage mothers differ from their peers both physically and psychologically, indicating early calibration to key ecological factors. Cohort data have not been deliberately collected to test life-history hypotheses within Western populations. Nonetheless, existing data sets can be used to pursue relevant patterns using socioeconomic variables as indices …

The Relationship Between Preterm Birth, Temperament, And Psychopathology, Renata Vaysman Jan 2013

The Relationship Between Preterm Birth, Temperament, And Psychopathology, Renata Vaysman

Legacy Theses & Dissertations (2009 - 2024)

The survival rates of preterm children have improved dramatically since the advent of new technologies and medical treatments. However, the long term behavioral implications of preterm birth are still being investigated. The current study sought to explore the relationships between birth status (preterm or full term), temperament, and psychopathology. A sample of preterm children and their parents, as well as a sample of age-matched controls and their parents, were recruited for participation in this study. The former group was recruited for participation through a local hospital while the latter group was recruited through flyer distributions in several local school districts. …
