Screens across the pond: Findings from longitudinal screen time research in the US and UK

Digital media are increasingly pervasive in the lives of young children. This increase in the availability of digital media might have long-run implications for child development; however, it is too soon to definitively conclude the direction of effects. In part due to this lack of certainty, leading health organizations have chosen to make different recommendations to parents of young children: Many international health organizations (e.g., the American Academy of Pediatrics, World Health Organization) recommend very young children be limited to under one hour of screen time daily, whereas others (e.g., Royal College of Paediatrics and Child Health) have intentionally opted not to make recommendations about specific limits. These guidelines might contribute to parents in different countries making meaningfully different choices about children’s use of digital media. Using a sample of N = 303 families recruited in Cambridgeshire, England and New York City prior to the birth of couples’ first child, we explore predictors of digital media use across the first two years of life. Data were collected when children were 4, 14, and 24 months of age. Results of latent growth curve analyses show that generally, children spend more time engaging with digital media as they grow older; however, growth mixture models reveal most children fit into one of two classes: One group of children (High Media Users; 52.2 %) engages with a substantial amount of digital media, whereas the other (Low Media Users; 48.8 %) engages with relatively little. Children in the US were approximately 30 % more likely to be in the Low Media Users group and there were no differences in group membership on the basis of parents’ psychosocial wellbeing. While these differences could be due to a number of factors, these findings may reflect the power of pediatric recommendations.

SUMMARY

In this paper, the author describes aspects of his work as a psychoanalytical psychotherapist in a hospital for diseases of the colon and rectum. After reviewing some of the earlier psychoanalytic literature (Freud and Abraham), and more recent theoretical contributions, two cases are described in some detail, which help give a flavour to some of the work. The paper concludes with caveats about the internal and external working environment, which will facilitate or hinder working in particular medical settings.     

Don't Take Out This Appendix! Generalizability of the Global Assessment of Relational Functioning Scale

This study investigated the generalizability of the Global Assessment of Relational Functioning (GARF) Scale. Found in an appendix of the Diagnostic and Statistical Manual of Mental Disorders under "Criteria Sets for Axes Provided for Future Study," the GARF Scale provides a global rating of a relational unit (family or couple). Thirty-two raters assigned GARF ratings to five relational units. Generalizability analyses indicate extremely high dependability of GARF scores across raters. Higher generalizability coefficients were found for raters who had formal education in family systems theory. Overall, these results are an encouraging step towards adopting the GARF for widespread use.     

A view of guidance from Africa

Modern Africa has achieved great progress in education, urbanization, and economic development. Modernization, however, brings the traditional into frequent confrontation with the modern and tends to create conflicts in the lives of individuals. Modern Africa's youth need guidance. But to be effective, guidance practice must be based on philosophies that reflect true African thinking. Foreign models will be inadequate. This article examines some African viewpoints in order to suggest elements that might be used in formulating a philosophy of guidance and a mode of practice suitable for Africa.     

A bird's eye view: biological categorization and reasoning within and across cultures

Many psychological studies of categorization and reasoning use undergraduates to make claims about human conceptualization. Generalizability of findings to other populations is often assumed but rarely tested. Even when comparative studies are conducted, it may be challenging to interpret differences. As a partial remedy, in the present studies we adopt a 'triangulation strategy' to evaluate the ways expertise and culturally different belief systems can lead to different ways of conceptualizing the biological world. We use three groups (US bird experts, US undergraduates, and ordinary Itza' Maya) and two sets of birds (North American and Central American). Categorization tasks show considerable similarity among the three groups' taxonomic sorts, but also systematic differences. Notably, US expert categorization is more similar to Itza' than to US novice categorization. The differences are magnified on inductive reasoning tasks where only undergraduates show patterns of judgment that are largely consistent with current models of category-based taxonomic inference. The Maya commonly employ causal and ecological reasoning rather than taxonomic reasoning. Experts use a mixture of strategies (including causal and ecological reasoning), only some of which current models explain. US and Itza' informants differed markedly when reasoning about passerines (songbirds), reflecting the somewhat different role that songbirds play in the two cultures. The results call into question the importance of similarity-based notions of typicality and central tendency in natural categorization and reasoning. These findings also show that relative expertise leads to a convergence of thought that transcends cultural boundaries and shared experiences.     

Emergentism by default: A view from the bench

For the last 50 years the dominant stance in experimental biology has been reductionism in general, and genetic reductionism in particular. Philosophers were the first to realize that the belief that the Mendelian genes were reduced to DNA molecules was questionable. Soon, experimental data confirmed these misgivings. The optimism of molecular biologists, fueled by early success in tackling relatively simple problems has now been tempered by the difficulties encountered when applying the same simple ideas to complex problems. We analyze three examples taken from experimental data that illustrate the shortcomings of this sort of reductionism. In the first, alterations in the expression of a large number of genes coexist with normal phenotypes at supra-cellular levels of organization; in the second, the supposed intrinsic specificity of hormonal signals is negated; in the third, the notion that cancer is a cellular problem caused by mutated genes is challenged by data gathered both from the reductionist viewpoint and the alternative view proposing that carcinogenesis is development gone awry. As an alternative to reductionism, we propose that the organicist view is a good starting point from which to explore these phenomena. However, new theoretical concepts are needed to grapple with the apparent circular causality of complex biological phenomena.     

Exercise psychology: A view from Europe

ObjectiveTo provide a review and commentary on developments and key issues in the psychology of health-related physical activity (‘exercise psychology’).Design and MethodNarrative review and commentary.ResultsA view from Europe is provided, with an emphasis on European influence and research. Summary commentaries are provided using the behavioural epidemiological framework as an organisational tool. The role of psychology is discussed in the study of physical activity correlates, theory, and interventions.ConclusionsThe European influence in exercise and health psychology has been significant. However, more needs to be known about pre-intentional motivation processes and post-intentional volition, as well as clarifying and extending theories (e.g., translating intentions into behaviour). There is also a need to do more intervention work, and to improve how we conduct, evaluate and report interventions. New issues are emerging, including the study of sedentary behaviour.     

Recovering memories of trauma: A view from the laboratory

The controversy over the validity of repressed and recovered memories of childhood sexual abuse (CSA) has been extraordinarily bitter. Yet data on cognitive functioning in people reporting repressed and recovered memories of trauma have been strikingly scarce. Recent laboratory studies have been designed to test hypotheses about cognitive mechanisms that ought to be operative if people can repress and recover memories of trauma or if they can form false memories of trauma. Contrary to clinical lore, these studies have shown that people reporting CSA histories are not characterized by a superior ability to forget trauma-related material. Other studies have shown that individuals reporting recovered memories of either CSA or abduction by space aliens are characterized by heightened proneness to form false memories in certain laboratory tasks. Although cognitive psychology methods cannot distinguish true memories from false ones, these methods can illuminate mechanisms for remembering and forgetting among people reporting histories of trauma.     

“Don't let the group down”: Facets of instrumentality moderate the motivating effects of groups in a field experiment

The motivating effects of group work as compared with individual work are not restricted to the research laboratory but have recently been documented in existing groups performing meaningful tasks. Freestyle swimmers at the 2008 Olympics were shown to swim faster in relay groups than in the individual competitions when their contribution was highly instrumental for the relay group (i.e., indispensable) because of their serial position in the group. The present study replicated and extended this work, aggregating a larger sample from major sports events (N = 199 freestyle swimmers) that also allowed for a competitive test between the instrumentality approach and explanations based on differences in the starting procedures of relay and individual competitions. Consistent with expectancy value models of effort expenditure in groups, swimmers were faster in the relay groups as compared with individual competitions only when (i) a swimmer's performance was highly instrumental for the group's performance (i.e., later serial position in the relay) and (ii) the group's performance was highly instrumental for a positive group outcome (i.e., the relay group had a good chance of winning a medal). The data were not consistent with an explanation of performance differences merely as a result of different starting procedures. Copyright © 2012 John Wiley & Sons, Ltd.
