How are physical literacy interventions conceptualized? – A systematic review on intervention design and content

The concept of physical literacy (PL) has gained increasing attention over the last decade and posits that individuals value and take responsibility for engagement in physical activities for life through (a) motivation/confidence, (b) physical competence, and (c) knowledge/understanding. There is a mounting number of articles that have recently transformed the conceptual ideas of PL into interventions. The goal of this pre-registered (PROSPERO CRD42020188926) systematic review was to analyze and summarize PL interventions in terms of design and content. A total of 18 databases were searched drawing on the 2020 preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Inclusion criteria were English language, publication by November 2020, and interventions based on or inspired by PL. Articles that met these criteria were analyzed in relation to basic delivery characteristics, theoretical foundations, study objectives, intervention content, and potential links between the PL domains (a-c) and content. The multiphase screening process with two independent raters yielded 44 eligible interventions across 46 articles. The analyses of the review demonstrated that the majority of interventions were conducted on children or adolescents and in countries with higher economic development. While 77.3% of the interventions adopted a holistic understanding of PL, only 38.6% formulated study goals or intervention content to cover all the core PL domains. Importantly, only 25.0% of the interventions showed substantial links between PL domains and intervention content and can thus be classified as theory-based. Taken together, most interventions targeted aspects of physical competence (84.1%), whereas knowledge/understanding (59.1%) and motivation/confidence (47.7%) were often neglected. Therefore, future interventions should commit to systematically address all domains of PL simultaneously. PL interventions exposed weaknesses in reporting delivery characteristics and content. Finally, a model is suggested which assumes that practical PL efforts may better harmonize with PL theory and conception if they cultivated a tight interlocking with the three core domains of PL at all stages of the intervention process.     

Never getting to zero: Elementary school students' understanding of the infinite divisibility of number and matter

Clinical interviews administered to third- to sixth-graders explored children's conceptualizations of rational number and of certain extensive physical quantities. We found within child consistency in reasoning about diverse aspects of rational number. Children's spontaneous acknowledgement of the existence of numbers between 0 and 1 was strongly related to their induction that numbers are infinitely divisible in the sense that they can be repeatedly divided without ever getting to zero. Their conceptualizing number as infinitely divisible was strongly related to their having a model of fraction notation based on division and to their successful judgment of the relative magnitudes of fractions and decimals. In addition, their understanding number as infinitely divisible was strongly related to their understanding physical quantities as infinitely divisible. These results support a conceptual change account of knowledge acquisition, involving two-way mappings between the domains of number and physical quantity.     

Developing a Cultural Theory of Mind: The CIAO Approach

The study of children's knowledge about minds is an extremely active area of developmental psychology. This article discusses the reach of this research and the theoretical views guiding it. It then presents some cultural variations (within the United States) in behavior explanation and explains the relevance of that variation to developmental theory. A theory ofearly mind reading that is presented incorporates culture, introspection, analogy, and ontogeny (CIAO).     

Development of a Situation-Response Inventory for Managerial Selection

The development is reported of an SR-inventory of achievement-related behaviour for the purpose of managerial selection. SR-inventories stem from interactional personality psychology. As the design of an SR-inventory is two-facetted, Cronbach et al.'s generalizability theory forms a suitable framework to investigate it. Using data of 404 Dutch respondents — mostly applicants — several generalizability analyses have been performed to conclude under which circumstances the inventory can be a useful tool. Furthermore, confirmatory factor analysis has been used to substantiate the suggested SR-structure of the instrument. The relationship with other personality factors has been investigated to classify the instrument in the domain of personality assessment.     

Participative work as an influence on human development

A number of business and industries in the United States and Europe have been experimenting with ways to involve more employees in organizational decision-making and problem-solving activities. Although the goal of such experiments in participative work is usually to improve productivity and enhance morale, there is evidence that working in such firms enhances adult development. This article reviews this evidence, focusing on how the experience of working in a participative milieu affects the individual in ways that are manifested off the job—in the family and community. Suggestions are made for future research that would involve developmental psychologists in helping work organizations experiment with planned social change.     

Ethnic and sex differences in occupational stereotyping by elementary school children

As part of the formative evaluation of an educational television and print package, fourth-, fifth-, and sixth-grade public school Black, Hispanic, and Anglo children were surveyed regarding career choice and perceptions of the appropriateness of selected occupations for male and female adults and children. Responses were analyzed by ethnic membership and sex. Results indicated that in general Hispanic and Anglo girls chose more non traditional, higher-status occupations than Black girls. For boys, however, there was no clear interaction between sex and ethnic group in career choice. Girls and boys in all three ethnic groups indicated preference for careers stereotyped for their own sex, although girls—particularly Anglo girls—showed a greater tendency to cross sex-stereotyped lines. In addition, while both girls and boys in all three groups stereotyped as appropriate only for females those occupations regarded as traditionally female, traditionally male occupations were stereotyped more frequently by boys than by girls, who tended to consider them appropriate for both sexes. No differences appeared between ethnic groups in boys' responses to male and female adult occupations. In general Black girls tended to hold the most stereotypic views of job appropriateness, while Hispanic girls did not show a clear trend. Black boys tended to stereotype more than the other two groups with reference to child jobs on a boy-stereotype scale. Some differences also appeared in both boys' and girls' responses on the basis of a median split between high and low stereotypers on boy and girl child-job stereotype scales. In general, subjects who stereotyped child jobs tended also to stereotype adult occupations, suggesting a link between the child's current experience and the more remote world of adults. Implications of the findings and suggestions for future research are discussed.     

Cross-sectional,longitudinal and composite longitudinal data on the Career Maturity Inventory Attitude Scale

Longitudinal data collection designs are frequently used in the study of developmental variables but typically yield patterns of results that are different from those obtained using cross-sectional designs. Recent research has focused on ways to clarify and reconcile the methodological distinctions between these two designs by utilizing alternative designs that incorporate features of both. This investigation compared the results obtained by the two traditional designs on the Career Maturity Inventory-Attitude Scale with the effects of an alternative design: constructing a composite longitudinal gradient. The two traditional methodologies yielded different results from each other for males, but not for females. However, the alternative design failed to eliminate the obtained differences for males, and introduced differences for females, casting doubt on the efficacy of the “solution.” The implications of these results for developmental research and career maturity were discussed.     

Synchronous and desynchronous changes during fear reduction.

The purpose of this experiment, carried out on 27 subjects with intense and circumscribed fears, was to test one main hypothesis and several subsidiary predictions. The prediction that a high-demand in vivo treatment condition produces desynchronous changes and a low-demand treatment condition synchronous changes, was supported by some inter-session findings but not by the intra-session findings. The clear linear relation between heart-rate and reported fear was confirmed, as was the rapid habituation of the heart-rate response to phobic stimulation.The fear-reactions and fear-reductions of psychiatric and non-psychiatric were indistinguishable. High heart-rate responders and low heart-rate responders showed similar patterns of improvement. The constrained laboratory ‘treatment’ procedure used in the experiment produced large and rapid reductions in fear.
