Children's competence and value beliefs from childhood through adolescence: Growth trajectories in two male-sex-typed domains.

The purpose of this study was to document gender differences in children's competence and value beliefs (N =514) from the 1st through 12th grades and to investigate the relation of these trends to initial differences in parents' perceptions of children's ability. Six separate growth models were tested: math competence, math interest, math importance, sports competence, sports interest, and sports importance. Across all 6 models, children's self-perceptions declined from 1st grade to 12th grade. Gender differences in competence and value beliefs were found. The gap between boys' and girls' competence beliefs decreased over time. In addition, parents' initial ratings of children's ability helped to explain mean level differences and variations in the rate of change in children's beliefs over time, with the effect being strongest in the sports models.

Intrinsic and extrinsic reading motivation as predictors of reading literacy: A longitudinal study.

The purpose in this study was to examine the longitudinal relationships of intrinsic and extrinsic motivation with reading literacy development. In particular, the authors (a) investigated reading amount as mediator between motivation and reading literacy and (b) probed for bidirectional relationships between reading motivation and reading literacy, controlling for previous reading literacy. A total of 740 students participated in a longitudinal assessment starting in Grade 3, with further points of measurement in Grades 4 and 6. Structural equation models with latent variables showed that the relationship between intrinsic reading motivation and later reading literacy was mediated by reading amount but not when previous reading literacy was included in the model. A bidirectional relationship was found between extrinsic reading motivation and reading literacy: Grade 3 reading literacy negatively predicted extrinsic reading motivation in Grade 4, which in turn negatively predicted reading literacy in Grade 6. Implications for research and practice are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

African Americans and boys: Understanding the literacy gap, tracing academic trajectories, and evaluating the role of learning-related skills.

In this study, the authors examined the racial and gender gap in the academic development of African American and White children from kindergarten to 5th grade. Their main goal was to determine the extent to which social and behavioral factors, including learning-related skills, problem behaviors, and interpersonal skills, explain these gaps and shed light on the academic difficulties specifically experienced by African American boys. The authors utilized the Early Childhood Longitudinal Study–Kindergarten Cohort (ECLS-K) sample and applied growth curve modeling. Learning-related skills explained the literacy development of African American boys over and above the effects of problem behaviors, socioeconomic status, and home literacy environment. Results suggest that emphasis placed on the behavior problems and the social risk factors associated with African American boys needs to be refocused and should be accompanied by increased efforts to improve learning-related skills in the classroom context and beyond.

Task values and ability beliefs as predictors of high school literacy choices: A developmental analysis.

This study examines how competence beliefs and task values predict high school achievement choices related to literacy. Students' task beliefs (self-concept of ability, intrinsic value, and importance) about reading in the 4th grade and English in the 10th grade were tracked over time. Task beliefs, school performance, and gender were used to predict students' (a) time per week spent reading for pleasure in 10th grade, (b) number of language arts courses per year of high school, and (c) reading relatedness of 12th-grade career aspirations. Results indicated that ability beliefs positively predicted all 3 outcomes, importance predicted career aspirations and course choices, and intrinsic value predicted leisure time reading and high school courses. Gender differences were also discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Motivation in a task situation as a function of ability and control over the task.

102 psychology students participated in the task of constructing and validating an "academic aptitude test." Training (level of ability) and amount of control over the task were manipulated in a 2 X 2 factorial design. For untrained Ss, performance was positively related to control. The performance of trained Ss was negatively related to control, contrary to prediction. This reversal was tentatively attributed to unintended "side effects" of the training manipulation. As predicted, expected success was positively related to training, perceived ability, and perceived control. A manipulation of success and failure in the task led to results consistent with predictions: Success produced incerases in satisfaction and perceived ability, while failure led to decreases in perceived ability.

Trajectories of social withdrawal from grades 1 to 6: Prediction from early parenting, attachment, and temperament.

From 1,092 children in the NICHD Study of Early Child Care and Youth Development, the authors identified 3 trajectory patterns of social withdrawal from teacher reports in Grades 1-6: a normative consistently low group (86%), a decreasing group (5%) with initially high withdrawal that decreased, and an increasing group (9%) with initially low withdrawal that increased. Prediction models supported the role of early dysregulated temperament, insensitive parenting, and attachment. Preschool shy temperament was a specific pathway to decreasing withdrawal, and poor inhibitory control was a specific pathway to increasing withdrawal. Children on the increasing pathway were more lonely, solitary, and were excluded by peers. Results suggest differentiated pathways to varying trajectories of social withdrawal and highlight the importance of identification of longitudinal patterns in relation to risk.

Sex Differences in Visuo-Spatial Ability: Task Difficulty, Speed-Accuracy Tradeoff, and Other Performance Factors.

Males have consistently been found to perform better than females on a task that requires the subject to mentally rotate a figure. Recently, Goldstein, Haldane, and Mitchell (1990) suggested that performance factors are operative in explaining sex differences in spatial ability. However, Stumpf (1993) was unable to replicate all of Goldstein et al.'s (1990) findings and to generalize them to other measures of spatial ability. In this study, it was hypothesized (1) that females would take longer to respond and would get fewer correct items than males on a spatial rotation task, and (2) that only females would show a speed-accuracy tradeoff as the difficulty of the spatial task increased from the 90° to 180° rotated conditions. The results confirmed each of these hypotheses. Furthermore, as Stumpf (1993) found, when ratio scores from the number of items correct to number attempted were computed for both males and females, differences in spatial ability were reduced, though still evident.

Growth trajectories of exercise self-efficacy in older adults: Influence of measures and initial status.

Objective: This study examined differential trajectories of exercise-related self-efficacy beliefs across a 12-month randomized controlled exercise trial. Method: Previously inactive older adults (N = 144; M age = 66.5) were randomly assigned to one of two exercise conditions (walking, flexibility-toning-balance) and completed measures of barriers self-efficacy (BARSE), exercise self-efficacy (EXSE), and self-efficacy for walking (SEW) across a 12-month period. Changes in efficacy were examined according to efficacy type and interindividual differences. Latent growth curve modeling was employed to (a) examine average levels and change in each type of efficacy for the collapsed sample and by intervention condition and (b) explore subpopulations (i.e., latent classes) within the sample that differ in their baseline efficacy and trajectory. Results: Analyses revealed two negative trends in BARSE and EXSE at predicted transition points, in addition to a positive linear trend in SEW. Two subgroups with unique baseline efficacy and trajectory profiles were also identified. Conclusion: These results shed new light on the relationship between exercise and self-efficacy in older adults. They also highlight the need for strategies for increasing and maintaining efficacy within interventions, namely targeting participants who start with a disadvantage (lower efficacy) and integrating efficacy-boosting strategies for all participants prior to program end.

Adjustment trajectories in college science programs: Perceptions of qualities of parents' and college teachers' relationships.

This longitudinal study had 2 goals. The 1st goal was to describe trajectories of academic and emotional adjustment in college science programs. The 2nd goal was to determine whether these trajectories differed as a function of students' self-reports of the quality of their relationships with parents and teachers. The sample consisted of 498 students recruited during their last year of high school. Assessment of adjustment continued until the end of the 2nd year of college. For a number of students, the authors observed a significant decline in both academic and emotional adjustment. Moreover, it was possible to identify an at-risk profile characterized by poor academic and emotional adjustment. In examining the students' perceptions of their family and school environments, the authors found that poorly and well-adjusted students differed from each other on the basis of parental but not teachers' relationship quality.

Dialogic reading and morphology training in Chinese children: Effects on language and literacy.

This study investigates the effects of parent-child shared book reading and metalinguistic training on the language and literacy skills of 148 kindergartners in Hong Kong. Children were pretested on Chinese character recognition, vocabulary, morphological awareness, and reading interest and then assigned randomly to 1 of 4 conditions: the dialogic reading with morphology training (DR + MT), dialogic reading (DR), typical reading, or control condition. After a 12-week intervention period, the DR intervention yielded greater gains in vocabulary, and the DR + MT intervention yielded greater improvement in character recognition and morphological awareness. Both interventions enhanced children's reading interest. Results confirm that different home literacy approaches influence children's oral and written language skills differently: Shared book reading promotes language development, whereas parents' explicit metalinguistic training within a shared book reading context better prepares children for learning to read.

Longitudinal findings from the normative aging study: III. Personality, individual health trajectories, and mortality.

Individual differences in physical and psychological health trajectories were examined in 1,515 Normative Aging Study men. Mean age at baseline was 47.15 yrs (range 28–80 yrs), and average follow up was 18.55 yrs (range 8–25 yrs). Both linear and nonlinear growth curves were estimated with random-effects models and then clustered to identify patterns of change. Men whose physical health trajectories were characterized by high, increasing symptoms were higher in hostility and anxiety, were overweight, and smoked. Those whose trajectories were characterized by low symptoms were emotionally stable, educated, nonsmokers, and thin. Men with high, stable psychological trajectories had high hostility; those with low, stable trajectories had high emotional stability; those with moderate anxiety levels had nonlinear trajectories with peaks in psychological symptoms at different life stages. Personality had life-long effects on health trajectories, but these effects varied across traits and health outcomes. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Socioeconomic differences in reading trajectories: The contribution of family, neighborhood, and school contexts.

In the present study, the authors use the Early Childhood Longitudinal Study, Kindergarten Cohort of 1998-1999, to examine the extent to which family, school, and neighborhood factors account for the impact of socioeconomic status (SES) on children's early reading. Through the use of hierarchical linear modeling techniques, growth curve models were estimated to depict children's reading trajectories from kindergarten to 3rd grade. Family characteristics made the largest contribution to the prediction of initial kindergarten reading disparities. This included home literacy environment, parental involvement in school, and parental role strain. However, school and neighborhood conditions contributed more than family characteristics to SES differences in learning rates in reading. The association between school characteristics and reading outcomes suggests that makeup of the student population, as indexed by poverty concentration and number of children with reading deficits in the school, is related to reading outcomes. The findings imply that multiple contexts combine and are associated with young children's reading achievement and growth and help account for the robust relation of SES to reading outcomes.

“Teacher effects” in early literacy development: Evidence from a study of twins.

It is often assumed that differences in teacher characteristics are a major source of variability in children's educational achievements. We examine this assumption for early literacy achievement by calculating the correlations between pairs of twin children who either shared or did not share a teacher in kindergarten, Grade 1, and Grade 2. Teacher effects—or, more strictly, classroom effects—would show up as higher correlations for same-class than for different-class twin pairs. Same-class correlations were generally higher than different-class correlations, though not significantly so on most occasions. On the basis of the results, we estimate that the maximum variance accounted for by being assigned to the same or different classrooms is 8%. This is an upper-bound figure for a teacher effect because factors other than teachers may contribute to variation attributable to classroom assignment. We discuss the limitations of the study and draw out some of its educational implications. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Family involvement in school and low-income children's literacy: Longitudinal associations between and within families.

Longitudinal data from kindergarten to 5th grade on both family involvement in school and children's literacy performance were examined for an ethnically diverse, low-income sample (N = 281). Within families, increased school involvement predicted improved child literacy. In addition, although there was an achievement gap in average literacy performance between children of more and less educated mothers if family involvement levels were low, this gap was nonexistent if family involvement levels were high. These results add to existing evidence on the value of family involvement in school by demonstrating that increased involvement between kindergarten and 5th grade is associated with increased literacy performance and that high levels of school involvement may have added reward for low-income children with the added risk of low parent education. As such, these results support arguments that family involvement in school should be a central aim of practice and policy solutions to the achievement gap between lower and higher income children.

Depression, self-esteem, and anger in emerging adulthood: Seven-year trajectories.

This study used a school-based community sample (N = 920) to examine trajectories of depressive symptoms, self-esteem, and expressed anger in the critical years of emerging adulthood (ages 18-25). Using data from 5 waves, the authors discovered that multilevel models indicated that, on average, depressive symptoms and expressed anger declined, whereas self-esteem increased. Between-persons predictors of variability in trajectories included gender (gender gaps in depressive symptoms and self-esteem narrowed), parents' education, and conflict with parents (depressive symptoms and expressed anger improved fastest in participants with highly educated parents and in those with higher conflict). Across time, increases in social support and marriage were associated with increased psychological well-being, whereas longer periods of unemployment were connected with higher depression and lower self-esteem. Emerging adulthood is a time of improving psychological well-being, but individual trajectories depend on specific individual and family characteristics as well as role changes.

Linear and network trajectories in creative lives: A case study of Walter and Roberto Burle Marx.

Two major trajectories appear in the creativity literature: linear trajectories, marked by acquisition of expertise through extensive practice leading to unique mastery; and network trajectories, wherein the creator is productive in several enterprises that interact. Between these poles are creators whose fields require understanding beyond a single domain. Both expertise and network aspects are needed in creativity. This case study focuses on how Walter and Roberto Burle Marx, Brazilian brothers who represent opposite ends of the continuum, embroidered their lives and included aspects from the opposite poles. Walter, representing the linear trajectory, became a pianist, conductor, musical promoter, and composer. Roberto, representing the network trajectory, created the field of tropical landscape design from his interests in art, music, plants, and nature.

Youth psychotherapy change trajectories and outcomes in usual care: Community mental health versus managed care settings.

Objective: The authors compared symptom change trajectories and treatment outcome categories in children and adolescents receiving routine outpatient mental health services in a public community mental health system and a private managed care organization. Method: Archival longitudinal outcome data from parents completing the Youth Outcome Questionnaire (Y-OQ) were retrieved for children and adolescents (4–17 years old) served in a community mental health system (n = 936, mean age = 12 years, 40% girls or young women, 28% from families of color) and a managed care organization (n = 3,075, mean age = 13 years, 45% girls or young women, race and ethnicity not reported). The authors analyzed Y-OQ data using multilevel modeling and partial proportional odds modeling to test for differences in change trajectories and final outcomes across the 2 service settings. Results: Although initial symptom level was comparable across the 2 settings, the rate of change was significantly steeper for cases in the managed care setting. In addition, 24% of cases in the community mental health setting demonstrated a significant increase in symptoms over the course of treatment, compared with 14% of cases in the managed care setting. Conclusions: These results emphasize the need for increased attention to negative outcomes in routine mental health services and provide a stronger foundation for identifying youth cases at risk for treatment failure. In addition, given the overall differences observed across treatment settings for average rate of change and deterioration rates, results suggest that setting-specific model heuristics should be used for identifying cases at risk for negative outcomes.
