A defensive mindset: A pattern of social information processing that develops early and predicts life course outcomes

The hypothesis was tested that some children develop a defensive mindset that subsumes individual social information processing (SIP) steps, grows from early experiences, and guides long-term outcomes. In Study 1 (Fast Track [FT]), 463 age-5 children (45% girls; 43% Black) were first assessed in 1991 and followed through age 32 (83% retention). In Study 2 (Child Development Project [CDP]), 585 age-5 children (48% girls, 17% Black) were first assessed in 1987 and followed through age 34 (78% retention). In both studies, measures were collected of early adverse experiences, defensive mindset and SIP, and adult outcomes. Across both studies, a robust latent construct of school-age defensive mindset was validated empirically (comparative fit index = .99 in each study) and found to mediate the impact of early child abuse (38% in FT and 29% in CDP of total effect) and peer social rejection (14% in FT and 7% in CDP of total effect) on adult incarceration.     

Latent Variable Modeling and Adaptive Testing for Experimental Cognitive Psychopathology Research

The adaptation of experimental cognitive tasks into measures that can be used to quantify neurocognitive outcomes in translational studies and clinical trials has become a key component of the strategy to address psychiatric and neurological disorders. Unfortunately, while most experimental cognitive tests have strong theoretical bases, they can have poor psychometric properties, leaving them vulnerable to measurement challenges that undermine their use in applied settings. Item response theory–based computerized adaptive testing has been proposed as a solution but has been limited in experimental and translational research due to its large sample requirements. We present a generalized latent variable model that, when combined with strong parametric assumptions based on mathematical cognitive models, permits the use of adaptive testing without large samples or the need to precalibrate item parameters. The approach is demonstrated using data from a common measure of working memory—the N-back task—collected across a diverse sample of participants. After evaluating dimensionality and model fit, we conducted a simulation study to compare adaptive versus nonadaptive testing. Computerized adaptive testing either made the task 36% more efficient or score estimates 23% more precise, when compared to nonadaptive testing. This proof-of-concept study demonstrates that latent variable modeling and adaptive testing can be used in experimental cognitive testing even with relatively small samples. Adaptive testing has the potential to improve the impact and replicability of findings from translational studies and clinical trials that use experimental cognitive tasks as outcome measures.     

‘Invisible’ teachers of literacy: collusion between siblings and teachers in creating classroom cultures

The promise to raise literacy standards significantly at age 11 in economically disadvantaged areas has been an important part of the present British Government's educational policy. Integral to this promise has been the introduction of official home/school ‘contracts’ or ‘agreements’, which oblige parents to engage in specific literacy activities with their children. However, evidence from a longitudinal study of family literacy practices in East London suggests that family and community members other than parents might play a crucial role in initiating young children into literacy. Siblings particularly have been found to be efficient ‘teachers’ of school literacy practices. In this paper, I investigate particularly ways in which an unspoken collusion takes place between teacher and older sibling revealed during ‘play school’ sessions in Bangladeshi British households in East London.     

Improving the Root Mean Square Error of Approximation for Nonnormal Conditions in Structural Equation Modeling

In this study, the authors investigated incorporating adjusted model fit information into the root mean square error of approximation (RMSEA) fit index. Through Monte Carlo simulation, the usefulness of this adjusted index was evaluated for assessing model adequacy in structural equation modeling when the multivariate normality assumption underlying maximum likelihood estimation is violated. Adjustment to the RMSEA was considered in 2 forms: a rescaling adjustment via the Satorra-Bentler rescaled goodness-of-fit statistic and a bootstrap adjustment via the Bollen and Stine adjusted model p value. Both properly specified and misspecifed models were examined. The adjusted RMSEA was evaluated in terms of the average index value across study conditions and with respect to model rejection rates under tests of exact fit, close fit, and not-close fit.     

Parents’ Metacognitive Knowledge: Influences on Parent–Child Interactions in a Science Museum Setting

Despite science learning in settings such as science museums being recognized as important and given increasing attention in science education circles, the investigation of parents’ and their children’s metacognition in such settings is still in its infancy. This is despite an individual’s metacognition being acknowledged as an important influence on their learning within and across contexts. This research investigated parents’ metacognitive procedural and conditional knowledge, a key element of their metacognition, related to (a) what they knew about how they and their children thought and learned, and (b) whether this metacognitive knowledge influenced their interactions with their children during their interaction with a moderately complex simulation in a science museum. Parents reported metacognitive procedural and conditional knowledge regarding their own and their children’s thinking and learning processes. Further, parents were aware that this metacognitive knowledge influenced their interactions with their children, seeing this as appropriate pedagogical action for them within the context of the particular exhibit and its task requirements at the science museum, and for the child involved. These findings have implications for exhibit and activity development within science museum settings.     

Effects of extracurricular activities on postsecondary completion for students with disabilities

The authors focused on participation in extracurricular activities as a way of improving the educational outcomes of children with disabilities. Regarding students in the general population, adolescent involvement in extracurricular activities has been shown to have a positive association with school involvement and adolescent self-esteem, academic achievement, and adolescent development. Using the Educational Longitudinal Study dataset, the authors conducted logistic regression analyses to examine the relationship between participation in high school–sponsored extracurricular activities and postsecondary degree completion for students with disabilities. Findings show a statistically significant association between postsecondary degree completion for students with disabilities and extracurricular activity participation, including extent and type of extracurricular activity. Students with disabilities who participate in high school extracurricular activities may have increased likelihood of completing a postsecondary degree. Implications for policy, practice, and future research are discussed.     

Associations of Home and Classroom Environments with Head Start Children's Code-Related and Oral Language Skills

This study used data from the Head Start Family and Child Experiences Survey (FACES) 2009 4-year-old cohort to examine associations among family characteristics, home and classroom environments, and the emergent literacy skills of Head Start children. Results from hierarchical linear models suggest that both family and classroom contexts play a unique and interactive role in supporting Head Start children's development of different sets of emergent literacy skills. Parental warmth was positively related to children's oral language skills (i.e., receptive and expressive vocabulary knowledge), and teachers' educational level and the quality of instructional support in the classroom were significantly associated with children's code-related skills (i.e., letter-name and letter-sound knowledge). Further, high-quality instructional support in the classroom buffered the negative influence of low maternal education on children's oral language skills. Interventions focusing on enhancing the quality of parent-child interactions, in addition to professional development for teachers designed to improve the quality of instructional support, may contribute to promoting the development of emergent literacy skills of young children from low-income families.     

KANT'S CONCEPTION OF RESPECT AND AFRICAN AMERICAN EDUCATION RIGHTS

Immanuel Kant envisioned a kind of respect in which one recognizes each human (1) as being not fully comprehensible by any human understanding, (2) as being an end in him‐ or herself, and (3) as being a potential source of moral law. In this essay, Gregory Lewis Bynum uses this conception of respect as a lens with which to examine African American education rights on three levels: the individual level (the level of individual persons' moral experience and moral significance), the community level (the level of the formation and sustaining of social groups that have value for humanity), and the global level (the level of a universal community of humanity). Bynum's goal in this examination is to strengthen our practical understanding of African Americans' right to education defined, in accordance with international human rights documents, as the right to an education that supports the full development of the human personality in a manner that respects students' “cultural identity, language, and values.”     

Muscle metabolism and performance improvement after two training programmes of sprint running differing in rest interval duration

Repeated-sprint training often involves short sprints separated by inadequate recovery intervals. The effects of interval duration on metabolic and performance parameters are unclear. We compared the effects of two training programmes, differing in rest interval duration, on muscle (vastus lateralis) metabolism and sprint performance. Sixteen men trained three times a week for 8 weeks, each training session comprising 2-3 sets of two 80-m sprints. Sprints were separated by 10 s (n = 8) or 1 min (n = 8). Both training programmes improved performance in the 100-, 200-, and 300-m sprints, but the improvement was greater in the 10-s group during the final 100 m of the 200- and 300-m runs. Independent of interval duration, training mitigated the drop of muscle ATP after two 80-m sprints. The drop in phosphocreatine and the increases in glucose-6-phosphate and fructose-6-phosphate after two 80-m sprints were greater in the 10-s group. In conclusion, training with a limited number of repeated short sprints (≤10 s) may be more effective in improving speed maintenance in 200- and 300-m runs when performed with a 1:1 rather than a 1:6 exercise-to-rest ratio. This may be due to a greater activation of glycolysis caused, in part, by the limited resynthesis of phosphocreatine during the very short rest interval.
