Three experiments assessed the development of children's part and configural (part-relational) processing in object recognition during adolescence. In total, 312 school children aged 7-16 years and 80 adults were tested in 3-alternative forced choice (3-AFC) tasks. They judged the correct appearance of upright and inverted presented familiar animals, artifacts, and newly learned multipart objects, which had been manipulated either in terms of individual parts or part relations. Manipulation of part relations was constrained to either metric (animals, artifacts, and multipart objects) or categorical (multipart objects only) changes. For animals and artifacts, even the youngest children were close to adult levels for the correct recognition of an individual part change. By contrast, it was not until 11-12 years of age that they achieved similar levels of performance with regard to altered metric part relations. For the newly learned multipart objects, performance was equivalent throughout the tested age range for upright presented stimuli in the case of categorical part-specific and part-relational changes. In the case of metric manipulations, the results confirmed the data pattern observed for animals and artifacts. Together, the results provide converging evidence, with studies of face recognition, for a surprisingly late consolidation of configural-metric relative to part-based object recognition.

Background. Previous research has shown that object recognition may develop well into late childhood and adolescence. The present study extends that research and reveals novel differences in holistic and analytic recognition performance in 7-12 year olds compared to that seen in adults. We interpret our data within a hybrid model of object recognition that proposes two parallel routes for recognition (analytic vs. holistic) modulated by attention. Methodology / Principal Findings. Using a repetition-priming paradigm, we found in Experiment 1 that children showed no holistic priming, but only analytic priming. Given that holistic priming might be thought to be more ‘primitive’, we confirmed in Experiment 2 that our surprising finding was not because children’s analytic recognition was merely a result of name repetition. Conclusions / Significance. Our results suggest a developmental primacy of analytic object recognition. By contrast, holistic object recognition skills appear to emerge with a much more protracted trajectory extending into late adolescence.

Previous research (e.g., Jüttner et al, 2013, Developmental Psychology, 49, 161-176) has shown that object recognition may develop well into late childhood and adolescence. The present study extends that research and reveals novel di erences in holistic and analytic recognition performance in 7-11 year olds compared to that seen in adults. We interpret our data within Hummel’s hybrid model of object recognition (Hummel, 2001, Visual Cognition, 8, 489-517) that proposes two parallel routes for recognition (analytic vs. holistic) modulated by attention. Using a repetition-priming paradigm, we found in Experiment 1 that children showed no holistic priming, but only analytic priming. Given that holistic priming might be thought to be more ‘primitive’, we confirmed in Experiment 2 that our surprising finding was not because children’s analytic recognition was merely a result of name repetition. Our results suggest a developmental primacy of analytic object recognition. By contrast, holistic object recognition skills appear to emerge with a much more protracted trajectory extending into late adolescence

Holistic face perception, i.e. the mandatory integration of featural information across the face, hasbeen considered to play a key role when recognizing emotional face expressions (e.g., Tanaka et al.,2002). However, despite their early onset holistic processing skills continue to improvethroughout adolescence (e.g., Schwarzer et al., 2010) and therefore might modulate theevaluation of facial expressions. We tested this hypothesis using an attentional blink (AB)paradigm to compare the impact of happy, fearful and neutral faces in adolescents (10–13 years)and adults on subsequently presented neutral target stimuli (animals, plants and objects) in a rapidserial visual presentation stream. Adolescents and adults were found to be equally reliable whenreporting the emotional expression of the face stimuli. However, the detection of emotional butnot neutral faces imposed a significantly stronger AB effect on the detection of the neutral targetsin adults compared to adolescents. In a control experiment we confirmed that adolescents ratedemotional faces lower in terms of valence and arousal than adults. The results suggest a protracteddevelopment of the ability to evaluate facial expressions that might be attributed to the latematuration of holistic processing skills.

This dissertation tested the effectiveness of a psychosocial intervention, the Personal Development in the Context of Relationships (PDCR) program. The aim of the PDCR seeks to foster the development (or enhancement) of a sense of identity and intimacy among adolescents who participate in the program. The PDCR is a psychosocial group intervention which utilizes interpersonal relationship issues as a context to foster personal development in identity formation and facilitate the development of an individual's capacity for intimacy. The PDCR uses intervention strategies which include skills and knowledge development, experiential group exercises, and exploration for insight. Participants consisted of 110 late adolescents. A mixed-subjects design (pre-post-follow up) was used to assess the effectiveness, efficacy and utility of the PDCR on the experimental condition relative to a content/social contact control group and a time control condition. Identity exploration and identity commitment were measured by the Ego Identity Process Questionnaire (EIPQ). Total intimacy and identity role satisfaction were measured by the Erikson Psychosocial Stage Inventory (EPSI). Relationship quality and closeness were measured by the Relationship Quality Scale (RQS) and the Relationship Closeness Inventory (RCI) in an effort to assess whether any potential impact on interpersonal relationships occurs. Mixed MANOVAs were used to analyze the data with results yielding significant values for increased total identity exploration from pre to post test and decreases in total identity commitment from pre to post to follow-up test in the experimental group relative to the control conditions on the EIPQ. Further results indicated increases in total intimacy from pre to post to follow-up test in the experimental group relative to the control conditions on the EPSI. No clear trends emerged from pre to post to follow-up test for the Relationship measures. Results are discussed in terms of both practical and theoretical implications. ^

The goal of this study was to examine the longitudinal effects of five family factors on alcohol use among adolescent males. The family factors included familism (family pride, loyalty, and cohesion), parent derogation (being put down by parents), parent/child communication, family alcohol problems and family drug problems. The study focused on the effects of the family factors reported by a sample of 451 White-non-Hispanic and African American males during early and mid-adolescence on (1) the intensity of alcohol use in mid-adolescence, and (2) the number of problems associated with alcohol use during the transition to young adulthood. The study also explored racial differences in the effects of the family factors. The data for this study were derived from a two-phase longitudinal epidemiologic cohort study of male and female adolescents enrolled in middle schools in Miami, FL. Data were collected at four points between 1990 and 2001. Linear and logistical regressions were used to analyze the effects of the family variables on the dependent variables. ^ The results of the analyses indicated that all of the family variables except family drug problems were statistically significant predictors of the level of alcohol use and alcohol-related problems. Familism had a moderate influence on both of the dependent variables at all data points, while parent derogation, parent/child communication and family alcohol problems were weak predictors. While the family factors varied by race, their impact on the dependent variables did not vary substantially. ^ This study had methodological shortcomings related to measurement and design that may have contributed to the weak influence of the variables. Future studies should explore possible mediating effects of these variables, and should employ more sensitive measures that are culturally appropriate. The results suggest that, since early family factors have long-term effects on children's substance-using behaviors, the family environment should be addressed in prevention and intervention efforts. ^

The current study was designed to explore the salience of parent and peer support in middle childhood and early adolescence across two time periods as indicated by measures of achievement (grade point average (GPA), Stanford Achievement Test (SAT) scores and teacher rated school adaptation) and well-being (loneliness, depression, self-concept and teacher-rated internalizing behaviors). ^ Participants were part of an initial study on social network relations and school adaptation in middle childhood and early adolescence. Participants at Time 1 (in the spring of 1997) included 782 children in grades 4 and 6 of eight lower and middle income public elementary schools. Participants (N = 694) were reinterviewed two years later in the spring of 1999 (Time 2). ^ Multivariate analyses of variance (MANOVA) were used to investigate the change in salience of parent and peer support from Time 1 to Time 2. In addition, Tukey-HSD (Honestly Significant Difference) post hoc tests were used to test the significance of the differences among the means of four support categories: (1) low parent-low friend, (2) low parent-high friend, (3) high parent-low friend, and (4) high parent-high friend. ^ Compensatory effects were observed for loneliness and self-concept at Time 1, as well as for SAT scores, self-concept and overall achievement at Time 2. Results were consistent with existing findings that suggest a competitive model of parent/peer influence on achievement during adolescence. This study affirms the need for a more contextual approach to research examining competing and compensatory effects on adolescent development. ^

Changes in the demographic structure of American families have highlighted the need to reevaluate fatherhood. Research illustrates that paternal involvement positively affects child development, but father absence has increased due to rising rates of divorce, cohabitation, and non-marital childbirth. There is evidence that other male figures can function as effective father surrogates. However, information is limited, particularly with respect to female development. ^ This study examined differences in well-being, achievement, and paternal support among girls in four father categories: (a) Biological Father, (b) Step-Father, (c) Surrogate Father, and (d) No Father. Maternal support, economic hardship, and life stressors were included as potential covariates. Interviews were conducted with an ethnically and economically diverse sample of 694 sixth and eighth grade children. The sample included boys to assess the extent to which the findings were unique to girls. Measures included quantitative and qualitative support from father figures and indices of self-esteem, loneliness, and depression. Standardized test scores and classroom grades were also obtained from school records. ^ Girls with biological fathers had higher achievement test scores than girls in the other father categories, but there were no other differences related to the presence or absence of a father-figure. Biological fathers also provided greater quantitative and qualitative support than step- and surrogate fathers. Surrogate fathers provided a greater amount but lower quality of support than step-fathers. ^ Girls who received lower levels of support from biological fathers reported lower self-esteem and greater loneliness, compared to fatherless girls and those receiving low support from other father figures, suggesting that low support from biological fathers may be especially distressing. On the other hand, girls with low biological father support had higher achievement scores compared to fatherless girls and those who received low support from step- and surrogate fathers. Thus, the mere presence of the biological father appears to facilitate achievement, regardless of the level of support he provides. ^ This study highlights the supportive characteristics of different father figures and their influence on well-being and achievement in females. Future research should focus on the dynamics of surrogate father relationships and the specific characteristics that differentially affect developmental outcomes. ^

This thesis compares two perspectives on the production of Holocaust memory: a novel that leads up to The Holocaust in Britain and one that reflects the hindsight perspective of a liberator in the Soviet Union. The novels are Virginia Woolf’s BETWEEN THE ACTS and Vasily Grossman’s LIFE AND FATE. The analysis offers a locus of analysis for the diasporic literary energy created by the catastrophe in the 20th and 21st centuries. The project offers a theorized standpoint on the role of literature on official historical archives. Proposing a method through which contemporary readers can engage the diasporic event of The Holocaust, the project adopts both the extended metaphor and literal expression of soundscapes. Soundscapes encompass the immaterial processes of memorialization and the literal sonic textures developed in Holocaust novels. The critical perspective incorporates contemporary notions of narratology, archival practices, and cultural manifestations of language into the notion of literary ethnomusicology.

John le Carré’s novels “The Spy Who Came in From the Cold” (1963), “Tinker, Tailor, Soldier, Spy” (1974), and “The Tailor of Panama” (1997), focus on how the main characters reflect the somber reality of working in the British intelligence service. Through a broad post-structuralist analysis, I will identify the dichotomies - good/evil in “The Spy Who Came in From the Cold,” past/future in “Tinker, Tailor, Soldier, Spy,” and institution/individual in “The Tailor of Panama” - that frame the role of the protagonists. Each character is defined by his ambiguity and swinging moral compass, transforming him into a hybrid creation of morality and adaptability during transitional time periods in history, mainly during the Cold War. Le Carré’s novels reject the notion of spies standing above a group being celebrated. Instead, he portrays spies as characters who trade off individualism and social belonging for a false sense of heroism, loneliness, and even death.

Background Understanding the causes of poor mental health in early childhood and adolescence is important as this can be a significant determinant of mental well-being in later years. One potential and relatively unexplored factor is residential mobility in formative years. Previous studies have been relatively small and potentially limited due to methodological issues. The main aim of this study was to investigate the relationship between early residential instability and poor mental health among adolescents and young adults in Northern Ireland.
Methods A Census-based record linkage study of 28% of children aged 0–8 years in 2001 in Northern Ireland (n=49 762) was conducted, with six monthly address change assessments from health registration data and self-reported mental health status from the 2011 Census. Logistic regression models were built adjusting for socioeconomic status (SES), household composition and marital dissolution.
Results There was a graded relationship between the number of address changes and mental ill-health (adjusted OR 3.67, 95% CIs 2.11 to 6.39 for 5 or more moves). This relationship was not modified by SES or household composition. Marital dissolution was associated with poor mental health but did not modify the relationship between address change and mental health (p=0.206). There was some indication that movement after the age of five was associated with an increased likelihood of poor mental health.
Conclusions This large study clearly confirms the close relationship between address change in early years and later poor mental health. Residential mobility may be a useful marker for children at risk of poorer mental health in adolescence and early adulthood

This dissertation aimed to investigate the development of motor competence in childhood and adolescence. As a starting point, a systematic review was conducted to investigate the instruments used for the evaluation of motor competence. This review identified a gap in the literature regarding the existence of an instrument to assess motor competence based on the three theoretical constructs (stability, locomotor, manipulative). In an attempt to fill this gap, a valid quantitative instrument was proposed. To meet this purpose, 584 children, between 6 and 14 years of age, were evaluated in nine motor tasks, three for each construct. The final instrument comprised two motor tasks for each construct (stability, locomotor, manipulative) and presented very good fit indexes. This instrument was used to analyse the motor competence behaviour by gender in different age groups, indicating that generally boys outperformed girls and both genders increased their performance across age groups. However, different motor competence growth rates appear in both genders across age groups. In addition, children with high and low motor competence were compared regarding some of their health related fitness variables. We found that, regardless of age and gender, the group with better motor proficiency always showed better results in health related fitness. We found positive moderate to high correlations between motor competence and the variables of cardiovascular fitness and muscular fitness, and an inverse correlation with body composition across the four age groups. We also found that motor competence explained 75% of the variance of the health related fitness for the total sample, with locomotion as the primary predictor. However, when analysing the four age groups, stability skills seem to play an important role in health related fitness in the transition from childhood to adolescence. In conclusion, educational and health policies should consider the development of motor competence as an essential strategy to promote healthy development throughout life.

Aims: Investigating tracking of fatness from childhood to adolescence, early adolescence to young adulthood and late adolescence to young adulthood. Subjects and methods: Participants from the Madeira Growth Study were followed during an average period of 7.2 years. Height, body mass, skin-folds and circumferences were measured, nine health- and performance-related tests were administered and the Baecke questionnaire was used to assess physical activity. Skeletal maturity was estimated using the TW3 method. Results: The prevalence of overweight plus obesity ranged from 8.2–20.0% at baseline and from 20.4–40.0% at followup, in boys. Corresponding percentages for girls were 10.6– 12.0% and 13.2–18.0%. Inter-age correlations for fatness indicators ranged from 0.43–0.77. BMI, waist circumference and sum of skin-folds at 8, 12 and 16-years old were the main predictors of these variables at 15, 19 and 23-years old, respectively. Strength, muscular endurance and aerobic fitness were negatively related to body fatness. Physical activity and maturation were independently associated with adolescent (15 years) and young adult (19 years) fatness. Conclusions: Over 7.2 years, tracking was moderate-to-high for fatness. Variance was explained by fatness indicators and to a small extent by physical fitness, physical activity and maturation.
