Developmental scientists are often interested in subgroups of people who share commonalities in aspects of development; these subgroups often cannot be captured directly but instead must be inferred from other information. Mixture models can be used in these situations. Two specific types of mixture models, latent profile transition analyses and…

Sentiment analysis is a computational method that automatically analyzes the valence of massive quantities of text. Basic sentiment analysis involves extracting and counting emotionally-laden keywords from passages of text (e.g., "hate," "love," "happy," "sad"). This study describes using sentiment analysis…

Manifestations of internalizing problems, such as specific symptoms of anxiety and depression, can change across development, even if individuals show strong continuity in rank-order levels of internalizing problems. This illustrates the concept of heterotypic continuity, and raises the question of whether common measures might be construct-valid…

Research suggests that individuals with autism spectrum disorder (ASD) have significant difficulties with adaptive behavior skills including daily living and functional communication skills. Few studies have examined the developmental trajectory of adaptive behavior across childhood and adolescence. The present study examined longitudinal…

One way to avert negative influences on well-being when confronted with blocked goals is the flexible adjustment of one's goals to the given situation. This study examines developmental differences in flexible goal adjustment (FGA) regarding age and gender in a sample of N = 815 participants (10 to 20 years; M = 13.63, SD = 2.60, 48.5% male).…

Although Eriksonian theory suggests that adolescents' sense of fidelity is a key component of healthy development, research on this psychosocial construct has been limited. The current study developed an index of youth fidelity, examined the developmental course of this construct, explored the influence of contextual factors on different fidelity…

This article suggests that ideas about adolescent brains and their development increasingly function as powerful truths in making sense of young people. In this context, the knowledge practices of the neurosciences and evolutionary and developmental psychology are deemed capable of producing what we have come to understand as the evidence on which…

Stanley Hall's (1904) description of adolescence as a time "suggestive of some ancient period of storm and stress when old moorings were broken and a higher level attained" is arguably one of developmental psychology's most vivid and powerful metaphors. Its relatively insignificant contribution to Hall's treatise (Arnett, 2006), the early demise…

This paper makes a fundamentally simple line of empirically supported argumentation. The increasing demands for high level student learning can best be achieved by the use of the substantive research evidence of the past decade demonstrating that developmentally oriented instruction facilitates academic, behavioral, and social performance. Most…

It has been argued that peers are the most important agent of adolescent socialization and, more specifically, that this socialization process occurs at the child-specific (or nonshared environmental) level (J. R. Harris, 1998; R. Plomin & Asbury, 2005). The authors sought to empirically evaluate this nonshared environmental peer influence…

Recently, experimental economists have become increasingly interested in behaviors relating to morality, and one of the main tools for examining these issues has been game theory. Even though developmental psychologists have investigated similar topics for decades, this research has found little resonance. Similarly, economists have only recently…

Introduces a notation system for representing the formal aspects of Erikson's theory of psychological development in adolescence (including consideration of stages and transitions from one stage to the next) and uses this notation system to raise and make some researchable questions regarding Erikson's conceptions of the crises of identity and…

Reviews the literature from two distinct disciplines, developmental psychology and literature, reflecting the emergence of adolescence as a recognized stage in human development. Describes both cognitive and stage theories of adolescence and medieval concerns as well as twentieth century interest. (JAC)

Describes the evolution of adolescence as a developmental stage and several psychological approaches to adolescent development. The discussion covers the need for adolescent literature to address physical, social, and emotional issues, and the need for librarians and teachers to be aware of the available literature. (29 references) (CLB)

Seeks to review varied meanings regression has held within psychoanalytic and developmental literatures; focus on the forms, frequencies, and functions of regression when examining data from two structural developmental models addressing dimensions of normative adolescent identity development; and consider precipitants for different forms of…
