Item Family Processes and Leisure Activity Involvement Across the High School Transition: The Mediating Roles of Adolescent Internalizing Problems and Self-Esteem(2010) Dashiell-Aje, Ebony N.; Rubin, Kenneth H; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Parents are among the most important socializing agents in adolescents' lives. The purpose of the current study was to examine the prospective relations between family processes and leisure activity involvement across the high school transition. Specifically, I explored the meditational role of adolescent psychological well-being (internalizing problems and self-esteem) in these relations. The first aim of the present study included two dimensions: 1) to examine whether there were prospective relations between family processes (maternal and paternal parenting) and adolescent leisure involvement across the high school transition; and 2) to investigate the extent to which psychological well-being mediated the relations between family processes and adolescent leisure activity choices, based on Eccles and Harold's (1991) research linking parenting dimensions to leisure outcomes. The second aim of this study was to explore whether boys and girls differed in the extent to which their psychological well-being mediated the relations between family processes and leisure activity involvement from the 8th to the 9th grade. It was hypothesized that perceptions of maternal and paternal parenting would differentially relate to adolescent leisure activity intensity and enjoyment. Likewise, I hypothesized that internalizing problems and self-esteem would act as mediators in these relations. Finally, I hypothesized that gender would moderate some of the meditational relations. OLS regression and bootstrapping techniques were used to test simple mediation and moderated mediation for all variables. Significant mediation effects emerged for relations between perceptions of paternal involvement and sports intensity and enjoyment through internalizing problems. Additionally, internalizing problems mediated the relation between perceptions of paternal support and sports enjoyment. An indirect effect emerged for the relation between adolescent's perceptions of maternal negativity and arts enjoyment through self-esteem. Subsequent hierarchical regressions revealed significant gender by family process interactions when predicting leisure involvement and one significant gender by internalizing problems interaction effect emerged when predicting social activity enjoyment. These findings suggest that maternal and paternal parenting play significant and differential roles in adolescent leisure activity involvement across the high school transition. These results also suggest that adolescent psychological well-being effects the relations between adolescent perceptions of parenting and their leisure activity involvement.Item FACTORS AFFECTING RATES OF SOCIAL BUFFERING IN JUVENILE RHESUS MACAQUES (Macaca mulatta)(2010) Herman, Khalisa N.; Fox, Nathan A; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The purpose of the current study was to investigate genetic and experiential contributions to social buffering between juvenile non human primates. A second aim was to investigate the role of behavioral displays during social buffering, in order to explain social buffering deficits in primates with a history of early social deprivation (Winslow et al., 2003). A total of 31 male rhesus macaques (mean age of 2 years) were videotaped during a Novel Cage Test with and without their homecage partner, and immediately following, blood samples were collected under anesthesia. Subjects were either reared with mothers and peers (mother reared, n=15) or without their mothers in the continuous presence of peers (peer reared, n =16). Cortisol concentrations and rh5-HTTLPR genotypes (long ( l ) and short ( s ) alleles) were generated from blood samples ( l/l =20, l/s =10, and s/s =1), and videos were coded for a variety of stress and affiliation behaviors. Genotype and rearing differences in social buffering of stress behaviors and neuroendocrine function were assessed. Rates of social buffering were also compared between a group of high display subjects that exhibited frequent behavioral displays (n =21) compared to a low display group (n=10). Additionally, the behavioral data were subjected to a lag sequential analysis to examine levels of contingent responsiveness, or the likelihood of behavioral displays occurring before affiliative responses (Bakeman et al., 1997). The results revealed social buffering deficits in the short allele, peer reared, and low display groups. Both the peer reared and low display groups were found to engage in less affiliative behaviors compared to the mother reared and high display groups respectively, while the short allele group appeared to receive less benefit from the presence of a familiar partner. Additionally, contingent responsiveness was identified as a feature of social buffering for the entire sample, but did not explain group differences in social buffering. Taken as a whole, this study identifies genetic and experiential vulnerability factors for social buffering. Furthermore, it adds to our knowledge of how behavioral displays are used during social buffering.Item Reward modulation of inhibitory control during adolescence: An age related comparison of behavior and neural function(2010) Hardin, Michael George; Fox, Nathan A; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The developmental period of adolescence is distinguished by a transition from the dependent, family-oriented state of childhood to the autonomous, peer-oriented state of adulthood. Related to this transition is a distinct behavioral profile that includes high rates of exploration, novelty-seeking, and sensation-seeking. While this adolescent behavioral profile generally aids in the transition to autonomy, it comes at a cost and is often related to excessive risk-taking behavior. Current models attribute the adolescent behavioral profile to a developmental discordance between highly sensitive reward-related processes and immature inhibitory control processes. Specifically, reward-related processes appear to develop in a curvilinear manner characterized by a heightened sensitivity to reward that peaks during adolescence. On the other hand, inhibitory processes show a protracted linear developmental trajectory that begins in childhood and continues gradually throughout adolescence. Thus, the unique developmental trajectories of these two sets of processes leave the adolescent with highly sensitive, reward-driven processes that can only be moderately regulated by gradually developing inhibitory processes. Despite the usefulness of these models of adolescent behavior, they remain incompletely supported by data, as few studies specifically examine the interaction between reward-related and inhibitory processing. The current study addresses this particular gap in the adolescent neural development literature by administering a reward-modified inhibitory control task to children, adolescents, and young adults during functional neuroimaging. Three key findings emerged from the current study. First, adolescents showed greater inhibition-related neural responses than both adults and children when potential monetary reward was available. Second, adolescents reliably showed greater striatal recruitment with reward than both adults and children. These differences in striatal response occurred as all three age groups showed significant reward-related behavioral improvements. Third, when reward was not present, adolescents and children showed deficient inhibitory behavior relative to adults. Findings from this study support models proposing interactive relationships between heightened adolescent sensitivity to reward and protracted development of inhibitory control. Additionally, the current findings expand these models by suggesting heightened adolescent sensitivity to reward may facilitate developmentally inefficient inhibitory control processes in a bottom-up manner.Item The Inluence of Cultural Identity and Intergroup Contact on Adolescents' Evaluations of Arab-Jewish Peer Relationships(2009) Brenick, Alaina Faye; Killen, Melanie; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Recent research has documented the negative intergroup attitudes between Jewish and Arab youth and adults in the Middle East (Bar-Tal & Teichman, 2005; Brenick et al., 2007; Cole et al., 2003), yet little is known about how these negative intergroup biases manifest in the same cultural communities removed from the daily stress and tension of an intractable conflict, and living in the U.S. Moreover, while negative intergroup tensions between Jews and Arabs and, cultural stereotyping, prejudice, and discrimination towards Muslim and Arab groups have increased in the U.S. (Alliance of Civilizations, 2006; Sheridan, 2006), they may still benefit from increased opportunities to engage in intergroup contact, which has been shown to reduce intergroup prejudice (see Pettigrew & Tropp, 2005). However, these attitudes have yet to receive much empirical scrutiny in the developmental literature. The present study investigated age related changes in the influence of intergroup contact and cultural identification on evaluations of Arab-Jewish intergroup friendships. The focus of this study was on how Jewish-American, Arab-American, and unaffiliated (e.g., non-Jewish, non-Arab) American adolescents evaluate exclusion and inclusion in peer situations between Jewish and Arab youth in the peer, home, and community contexts. This study surveyed 953 ninth and twelfth graders (36 Arab participants, 306 Jewish participants, and 591 unaffiliated participants (259 in the Jewish comparison group and 332 in the Arab comparison group). Overall, all participants were primarily rejecting of intergroup exclusion, more so when the exclusion was based on cultural group membership than when no reason for the exclusion was specified. Further, males were more accepting of the intergroup exclusion and more accepting of including an ingroup member as compared to females. Context effects emerged revealing that intergroup exclusion was considered most acceptable in the community context and the least acceptable in the friendship context. The interactive influence of intergroup contact and cultural identification demonstrated that high levels of intergroup contact and high levels of identity commitment predicted less accepting ratings of intergroup exclusion, whereas high levels of intergroup contact and high levels of identity exploration, led to more accepting ratings of intergroup exclusion. These interactions varied by cultural group.Item LOW-INCOME TEEN FATHERS' TRAJECTORY OF INVOLVEMENT: THE INFLUENCE OF INDIVIDUAL, CONTEXTUAL, AND COPARENTAL FACTORS(2009) Holmes, Allison; Harden, Brenda J; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)While teen births are on the rise and marriage rates are on the decline, fathers have become a recent focus. However, there is a dearth of literature on teen fathers' parenting behaviors. The current study provided a portrait of Early Head Start teen fathers' involvement throughout early childhood and salient influences on that involvement. This study maximized developmental and life course perspectives by employing a longitudinal analysis (i.e., Latent Growth Curve Model) that emphasized time-effects. The majority of teen fathers were involved with children initially, but their involvement decreased over time. Consistent with extant literature, teen fathers who were prenatally engaged, resident after the birth, and in romantic coparental relationships at 14- and 24-months were more involved in their children's lives initially. Teen fathers who were in romantic coparental relationships at 36- and 64- months were less likely to decrease their involvement over the course of early childhood. Surprisingly, age, race, employment, and school status were not significant influences on father involvement. Although the present study had its limitations, trends were noted and should be considered in future studies. Teen fathers are a unique population facing several challenges to meeting their own developmental needs and enacting their father role. Some conceptual factors shown to be influential for father involvement with adult and married fathers (i.e., age, employment) do not hold the same meaning and impact among teen fathers. The conceptual and ultimately practical meaning of behaviors and characteristics must be contextualized within teen fathers' developmental trajectory and ecological settings. Similarly, examination of teen fathers within a dynamic, longitudinal framework emphasized the need to address fatherhood in a different way. Previous studies have examined longitudinal data, but not examined the patterns of involvement for individual fathers. This different perspective (i.e., person-centered) revealed unique patterns for teen fathers. Further analyses will allow when and how to best intervene with teen fathers. Teen fathers may be at-risk, but they are involved with their children and can positively benefit both children and mothers. Head Start and Early Head Start could continue to support teen fatherhood through its mission to serve low-income children and parents; availability from pregnancy through 5-years; and mission to adapt to the needs of the community and family. But without support or intervention, the cycle of teen of parenthood is perpetuated.Item The nature of bi-ethnic identity in young adults of Asian and European descent and their perceptions of familial influences on its development(2009) Wagner Hoa, Amanda Laurel; Wigfield, Allan; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The purpose of this study was to identify the key constructs of bi-ethnic identity, the key familial influences, and other salient influences on bi-ethnic identity as perceived by young adults of Asian and European descent. The rapidly changing demographics of the United States provide an impetus for research on the developmental processes of bi-ethnic individuals. In this qualitative study, participants were interviewed about their bi-ethnic identities and possible influences on bi-ethnic identity development. Data analysis for this study incorporated techniques from grounded theory (Strauss & Corbin, 1990) and analytic induction (LeCompte & Preissle, 1993). Five bi-ethnic identity types emerged from participants' responses to interview questions: majority identity, minority identity, dual identity, integrated identity, and unresolved identity. These identity types are a unique contribution to the literature in that they specify how individuals of Asian and European descent define themselves. Additionally, this study identified four facets of bi-ethnic identity that indicate how bi-ethnic individuals think and feel about their background: centrality, self-label, affirmation, and affect. Six categories of influences on bi-ethnic identity development emerged from responses to interview questions (parental, extended family, personal, peer, environmental, discrimination), with 18 subcategories. This study is important because most prior research on bi-ethnic identity has focused on uncovering developmental stages, while we lack understanding of the nature of bi-ethnic identity and influences on its development. This study was important given the dearth of research on bi-ethnic Asians, although future research is needed with other bi-ethnic groups.Item A MULTILEVEL ANALYSIS OF CONTEXT EFFECTS ON ADOLESCENT CIVIC ENGAGEMENT: THE ROLE OF FAMILY, PEERS, SCHOOL, AND NEIGHBORHOOD(2009) Wilkenfeld, Britt Skeens; Torney-Purta, Judith; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The relations between multiple contexts of influence and adolescents' civic engagement were examined in order to facilitate understanding of how adolescents are being prepared for citizenship. This study extends previous research by simultaneously examining the family, peer, school, and neighborhood contexts, including how contexts are interrelated in their influence, and by employing multilevel regression techniques. The purpose of the study was to understand how contexts interact to produce positive outcomes for adolescents, especially those deemed at risk for poor civic outcomes. Utilizing data from the 1999 Civic Education Study and the 2000 U.S. Census, I examined a nationally representative sample of 2,729 14-year-olds from 119 schools in the United States. Access to the zip-codes for each school that participated in the study enabled the connection between neighborhood characteristics and schools and students within schools. Given the multifaceted nature of civic engagement, the current study considered context effects on four different aspects of civic engagement: civic knowledge, support for the rights of ethnic minorities, anticipated voting behavior, and anticipated community participation. Predictors pertain to adolescents' demographic characteristics, political discourse with parents and peers, civic experiences in school, and the demographic composition of the neighborhood. Political discourse with parents was positively related to civic knowledge, attitudes, and anticipated behavior, indicating the consistency with which socialization occurs in the home. Across the contexts examined, student measures of civic experiences in school (or civic learning opportunities) had the most consistently positive relationships with students' civic outcomes. Civic experiences in school include student confidence in the effectiveness of school participation, perception of a classroom climate that is open for discussion, and learning about ideal civic practices. Interactions between the school and neighborhood contexts indicate that higher levels of civic learning opportunities particularly make a difference for students attending schools in impoverished neighborhoods, sometimes substantially improving their civic outcomes. Schools, although implicated in the existence of a civic engagement gap, have the potential to narrow the gaps. Civic experiences in schools contribute to the preparation of youth for active citizenship and full access to these experiences reduces civic engagement gaps between students of different demographic groups.Item CHILDREN'S PERCEPTIONS OF THEIR RELATIONSHIPS WITH MOTHERS, FATHERS AND FRIENDS: A CROSS-CULTURAL STUDY(2008) Oh, Wonjung; Rubin, Kenneth; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The purpose of this study was to cross-culturally examine children's perceptions of their relationships with mothers, fathers and friends among South Korean and European-American children. During middle childhood and preadolescence, although parent-child relationships are presumed to be the primary source of social support, friendships become increasingly salient; provisions for closeness and interdependence begin to shift from parents to friends. Researchers, however, have mostly examined mother-child and father-child relationships and friendships in isolation. The present study examined children's mother-child and father-child relationships and friendships as relationship networks in terms of various latent relationship constructs (social provisions; negative interactions; power distance). Of particular interest was whether the traditional emphasis on the family system in the South Korean culture would reveal distinct patterns of children's relationships with their mothers, fathers and friends. Participants included the South Korean and the European-American children ages 10 to 11 years old from two-parent families in the Seoul and the Washington D.C. Metropolitan Area. Variable-centered and person-centered approaches were employed to address individual differences (latent classes) on relationship qualities. Results revealed both cultural dissimilarities and similarities. Cultural differences were found in the mean levels of affection, conflict, and punitive aspects. The South Korean children perceived more social provisions from their mothers and fathers than from their friends, whereas the European-American children perceived similar levels of social provisions from their mothers, fathers and friends. Despite the changes in today's South Korean society, the South Korean family system continues to play a major role in providing social provisions for South Korean children. Cultural similarities were found regarding the patterns of relationship networks on power distance in both of the South Korean and European-American samples. Structural Equation Modeling also revealed structural invariance in terms of the manner in which the relationship constructs were associated with children's satisfaction with their mothers and fathers. In addition, considerable heterogeneity was revealed in affection, punitive aspects, and power distance. Taken together, findings from the present study highlight the importance of considering cross-cultural perspectives as well as person-centered approaches in the examination of relationship qualities.Item The Relations of Children's Perceived Support for Recreational Reading from Parents and Friends to Their Motivation for Reading(2008-11-17) Klauda, Susan Lynn Lutz; Wigfield, Allan; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This study investigated children's perceived support for their recreational reading from their mothers, fathers, and friends in relation to their reading motivation and habits. Models from the reading domain, including the engagement model of reading (Guthrie & Wigfield, 2000) and McKenna's (1994) model of reading attitude acquisition guided the study, as well as theories from the broader study of motivation, including self-determination theory (Ryan & Deci, 2000a) and expectancy-value theory [Eccles (Parsons) et al., 1983]. The study focused on children in the upper elementary grades, as relatively little research has examined the role that socialization agents play in this age group's reading motivation and activity. Participants, who included 130 fourth-graders and 172 fifth-graders, completed the newly developed Reading Support Survey (RSS) and surveys of their reading motivation and habits. Scores on three reading achievement indicators were obtained. Seven hypotheses were tested, six of which were partially or fully substantiated. Paired sample comparisons that examined individual RSS items indicated that children perceived greater reading support from their mothers than their fathers and friends in several regards. Factor analysis demonstrated the multidimensionality of perceived reading support. Four dimensions were apparent, but differed from those predicted in that support type was an organizing element as much as support source. Girls perceived greater friend support than boys, and fourth-graders reported receiving more books as presents than fifth-graders. Girls and fourth-graders showed somewhat more positive profiles of reading motivation and frequency. Each of the four dimensions of reading support correlated significantly with at least three of five reading motivation dimensions and three of four reading frequency variables studied. Moreover, multiple regression analyses indicated that parent and friend support contributed uniquely to the prediction of reading motivation and frequency, controlling for reading achievement, gender, and grade level. Additionally, cluster analysis indicated that participants could be grouped into five clusters based on their profiles of reading support; further analyses showed how these clusters differed in reading motivation and frequency.Item Maternal Adolescent Parenting Behavior and Child Aggressive and Inattentive Behavior: Findings from the Early Head Start Research and Evaluation Project(2008-11-17) Guner, Bella Mironovna; Klein, Elisa L; Jones Harden, Brenda; Human Development; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Adolescent parenting is associated with a wide variety of risk factors for both the mother (Berlin, Brady-Smith, & Brooks-Gunn, 2002) and child (Moore & Brooks-Gunn, 2002). Understanding the pathways leading toward poor parenting practices, and the subsequent influences on child aggressive and inattentive behavior may yield important information for intervention efforts on the part of adolescent families. The current study examines which maternal characteristics influence parenting behavior in a high risk sample of adolescent mothers and their toddlers, using Belsky's (1984) parenting process model. The purpose of the study was to: 1) examine whether maternal age, depression, or stress influenced positive and negative parenting behavior, 2) examine the influence of positive and negative parenting behavior on child aggressive and inattentive behavior, and 3) examine whether positive parenting would mediate the association between maternal characteristics and child aggressive and inattentive behavior. Data from the Early Head Start Research and Evaluation dataset was used to examine the aforementioned questions. The sample consisted of 319 mothers ages 15-19 and their toddlers ages 2-3 years. Heirarchical regression analyses revealed that maternal depression predicted higher levels of negative parenting behavior, younger adolescent mothers are more likely to engage in punitive parenting behavior than older adolescents, and maternal stress predicted lower levels of positive and higher levels of negative parenting behavior. Logistic regression analyses revealed that adolescent mothers who engaged in positive parenting behavior were less likely to have children who engaged in aggressive and inattentive behavior, and parents who engaged in negative parenting behavior were more likely to have children who engaged in aggressive and inattentive behavior. Mediational analyses revealed that positive parenting behavior mediated the association between maternal stress and child aggressive and inattentive behavior. These findings suggest that maternal characteristics are an important factor to consider in parenting behavior, and that despite the difficulties faced by adolescent mothers, there is room for positive parenting, which may mitigate the influence of maternal stress. The findings from this study indicate that intervention efforts may benefit from focusing on teaching adolescent mothers how to engage in positive parenting behaviors with their toddlers, thereby reducing the risk for future child aggressive and inattentive behaviors.
