Secondary attachments and adolescent self concept

This study examined the popular notion that crushes or secondary attachments to celebrity figures are an important aspect of self-concept development during adolescence. In a repeated measures design, 79 male and female 5th, 8th, and 11th graders and college sophomores completed a set of personality scales, first describing themselves and later, describing the favorite celebrity. Repeated measures multivariate analyses of variance (MANOVA) analysis of self-object congruence revealed no significant main or interaction effects for the type of attachment, gender, or age of subject. Significant within subject effects were obtained for the repeated measures factor (self-object congruence). Overall, students perceived their attachment objects to be more agentic, yet less expressive and emotionally vulnerable than themselves. MANOVA analyses indicated that males and older students perceived their attachment objects to be higher in agency than expressivity, whereas females and younger students perceived their attachment objects to be higher in expressivity than agency. These data indicate that the function served by secondary attachments in the development of self-concept may be quite similar for adolescent males and females.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45592/1/11199_2004_Article_BF00288191.pd

The Influence of Behavioral, Social, and Environmental Factors on Reproducibility and Replicability in Aquatic Animal Models

The publication of reproducible, replicable, and translatable data in studies utilizing animal models is a scientific, practical, and ethical necessity. This requires careful planning and execution of experiments and accurate reporting of results. Recognition that numerous developmental, environmental, and test-related factors can affect experimental outcomes is essential for a quality study design. Factors commonly considered when designing studies utilizing aquatic animal species include strain, sex, or age of the animal; water quality; temperature; and acoustic and light conditions. However, in the aquatic environment, it is equally important to consider normal species behavior, group dynamics, stocking density, and environmental complexity, including tank design and structural enrichment. Here, we will outline normal species and social behavior of 2 commonly used aquatic species: zebrafish (Danio rerio) and Xenopus (X. laevis and X. tropicalis). We also provide examples as to how these behaviors and the complexity of the tank environment can influence research results and provide general recommendations to assist with improvement of reproducibility and replicability, particularly as it pertains to behavior and environmental complexity, when utilizing these popular aquatic models. © The Author(s) 2020.
