Change in physical self-perceptions across the transition to secondary school: Relationships with perceived teacher-emphasised achievement goals in physical education

ObjectivesThis study aimed to examine the effects of change in perceived teacher achievement goal emphasis in physical education (PE) on physical self-perceptions and self-esteem across the transition to secondary school.Design & methodsA longitudinal design was adopted with three time points, one at the end of primary school and two during the first year of secondary school. Participants (N = 491) were cross-classified by primary (N = 42) and secondary (N = 46) PE class in order to examine the association between perceived class-level teacher-emphasised goals and within-class student goals with self-beliefs.ResultsPersonal approach goals and class perceptions of teacher mastery approach goal promotion were all positively associated with ratings of co-ordination, sport competence, flexibility, and endurance in primary school. More favourable perceptions of coordination, sport competence, strength, flexibility, and endurance during the first year of secondary school were predicted by an increase in performance approach goal emphasis, whereas ratings of sport competence and flexibility were negatively associated with an increase in mastery approach goal emphasis.ConclusionsAlthough not entirely consonant with theoretical predictions, current findings suggest that teacher-emphasised performance approach goals in PE can promote development of several physical self-perceptions in the initial year of secondary school.     

Applying Recent Argumentation Methods to Some Ancient Examples of Plausible Reasoning

Plausible (eikotic) reasoning known from ancient Greek (late Academic) skeptical philosophy is shown to be a clear notion that can be analyzed by argumentation methods, and that is important for argumentation studies. It is shown how there is a continuous thread running from the Sophists to the skeptical philosopher Carneades, through remarks of Locke and Bentham on the subject, to recent research in artificial intelligence. Eleven characteristics of plausible reasoning are specified by analyzing key examples of it recognized as important in ancient Greek skeptical philosophy using an artificial intelligence model called the Carneades Argumentation System (CAS). By applying CAS to ancient examples it is shown how plausible reasoning is especially useful for gaining a better understanding of evidential reasoning in law, and argued that it can also be applied to everyday argumentation. Our analysis of the snake and rope example of Carneades is also used to point out some ways CAS needs to be extended if it is to more fully model the views of this ancient philosopher on argumentation.     

From ABLE to TAPAS: A New Generation of Personality Tests to Support Military Selection and Classification Decisions

This article discusses 3 modern forced-choice personality tests developed for the U.S Armed Services to provide resistance to faking and other forms of response distortion: the Assessment of Individual Motivation, the Navy Computerized Adaptive Personality Scales, and the Tailored Adaptive Personality Assessment System. These tests represent the transition from Likert to forced-choice formats and from static to computerized adaptive item selection to meet the challenges of large-scale, high-stakes testing environments. For each test, we briefly describe the personality constructs that are assessed, the response format and scoring methods, and selected ongoing research and development efforts. We also highlight the potential of these tests for personnel selection, classification, and diagnostic screening purposes.     

Epigenetics and Child Psychiatry: Ethical and Legal Issues

Epigenetics has the potential to revolutionize diagnosis and treatment in psychiatry, especially child psychiatry, as it may offer the opportunity for early detection and prevention, as well as development of new treatments. As with the previous introduction of genetic research in psychiatry, there is also the problem of unrealistic expectations and new legal and ethical problems. This article reviews the potential contributions and problems of epigenetic research in child psychiatry. Previous legal and ethical issues in genetic research serve as a guide to those in epigenetic research. Recommendations for safeguards and guidelines on the use of epigenetics with children and adolescents are outlined based on the identified issues. Copyright © 2015 John Wiley & Sons, Ltd.     

Partiality and distributive justice in African bioethics

African ethical theories tend to hold that moral agents ought to be partial, in the sense that they should favour members of their family or close community. This is considered an advantage over the impartiality of many Western moral theories, which are regarded as having counterintuitive implications, such as the idea that it is unethical to save a family member before a stranger. The partiality of African ethics is thought to be particularly valuable in the context of bioethics. Thaddeus Metz, in particular, argues that his African-derived theory best accounts for a number of plausible intuitions, such as the intuition that health care practitioners ought to be biased towards the patients for whom they are directly responsible. In this article, I claim that the plausible intuitions drawn on in favour of partiality can be satisfactorily explained on the basis of impartial moral theories. Moreover, I argue that blanket acceptance of partiality has problematic consequences for distributive justice in resource allocation in biomedical contexts. By contrast, impartial theories can justify plausible instances of partiality whilst avoiding the pitfalls of fully partial moral theories. Although this provides grounds for abandoning partiality in principle, I claim that this finding should not be seen as damaging to African medical ethics. Instead, it prompts investigation of underexplored possibilities of impartial African moral theories. To demonstrate the value of this direction, I sketch some novel and attractive conceptions that combine impartiality with elements of African ethics.     

On the dark side of work: a longitudinal analysis using self-determination theory

As the nature of work has changed in recent decades, employees are increasingly exposed to psychological demands in the workplace, which have associated consequences for employees, organizations, and society. Using self-determination theory, this study examined the dark side of work, in which frustration of basic psychological needs is associated with higher levels of work-related stress. In this model, work-related stress is associated with higher levels of somatic symptom burden, which in turn is associated with higher levels of emotional exhaustion, turnover intention, and absenteeism. Results of a longitudinal analysis using data from four time points over 15 months supported these predictions. Taken together, this study advances the literature towards an understanding of the (potential) detrimental impact that need-thwarting work contexts can have on employee wellness and work-related outcomes.     

Genetic and environmental influences on early literacy skills across school grade contexts

Recent research suggests that the etiology of reading achievement can differ across environmental contexts. In the US, schools are commonly assigned grades (e.g. ‘A’, ‘B’) often interpreted to indicate school quality. This study explored differences in the etiology of early literacy skills for students based on these school grades. Participants included twins drawn from the Florida Twin Project on Reading (n = 1313 pairs) aged 4 to 10 years during the 2006–07 school year. Early literacy skills were assessed with DIBELS subtests: Oral Reading Fluency (ORF), Nonsense Word Fluency (NWF), Initial Sound Fluency (ISF), Letter Naming Fluency (LNF), and Phoneme Segmentation Fluency (PSF). School grade data were retrieved from the Florida Department of Education. Multi‐group analyses were conducted separately for subsamples defined by ‘A’ or ‘non‐A’ schools, controlling for school‐level socioeconomic status. Results indicated significant etiological differences on pre‐reading skills (ISF, LNF, and PSF), but not word‐level reading skills (ORF and NWF). There was a consistent trend of greater environmental influences on pre‐reading skills in non‐A schools, arguably representing ‘poorer’ environmental contexts than the A schools. Importantly, this is the case outside of resources linked with school‐level SES, indicating that something about the direct environment on pre‐reading skills in the non‐A school context is more variable than for A schools.     

Individual Differences in Early Scientific Thinking: Assessment,Cognitive Influences,and Their Relevance for Science Learning

ABSTRACT

Early scientific thinking in kindergarten (6-year-olds) was investigated in a large study involving 227 participants. We investigated (1) whether individual differences across 3 scientific-thinking components (experimentation, data interpretation, and understanding the nature of science) are stable across children, (2) whether children’s increased information-processing skills (intelligence, language abilities) and their development of an advanced theory of mind (AToM) are potential mechanisms that bring about individual differences in scientific thinking, and (3) whether individual differences in scientific thinking predict individual differences in science content knowledge. Using a newly developed instrument with 30 items (the Science-K inventory), we found that a one-dimensional Rasch model provides a good fit to the data, showing that kindergarteners’ scientific thinking goes beyond competencies in single tasks. Individual differences across the diverse scientific-thinking tasks were stable, and children’s scientific thinking was correlated with their intelligence and their language abilities. AToM was an important precursor for scientific thinking, predicting it independently from the influences of information-processing skills. Children’s science content knowledge was predicted by their score on the Science-K inventory. This finding points to a specific relation between these 2 components of scientific literacy, and it supports the view that scientific-thinking skills help to better test and revise (wrong) beliefs and misconceptions about science. Our study is the first to reveal substantial individual differences in scientific thinking in children as young as kindergarteners, and it shows that scientific thinking is important for a successful learning of science concepts, even before children enter formal schooling and begin science education.     

Belief in Conspiracy Theories and Susceptibility to the Conjunction Fallacy

People who believe in the paranormal have been found to be particularly susceptible to the conjunction fallacy. The present research examines whether the same is true of people who endorse conspiracy theories. Two studies examined the association between conspiracist ideation and the number of conjunction violations made in a variety of contexts (neutral, paranormal and conspiracy). Study 1 found that participants who endorsed a range of popular conspiracy theories more strongly also made more conjunction errors than participants with weaker conspiracism, regardless of the contextual framing of the conjunction. Study 2, using an independent sample and a generic measure of conspiracist ideation, replicated the finding that conspiracy belief is associated with domain‐general susceptibility to the conjunction fallacy. The findings are discussed in relation to the association between conspiracism and other anomalous beliefs, the representativeness heuristic and the tendency to infer underlying causal relationships connecting ostensibly unrelated events. © 2014 The Authors.

Evidence for preserved representations in change blindness

People often fail to detect large changes to scenes, provided that the changes occur during a visual disruption. This phenomenon, known as "change blindness," occurs both in the laboratory and in real-world situations in which changes occur unexpectedly. The pervasiveness of the inability to detect changes is consistent with the theoretical notion that we internally represent relatively little information from our visual world from one glance at a scene to the next. However, evidence for change blindness does not necessarily imply the absence of such a representation---people could also miss changes if they fail to compare an existing representation of the pre-change scene to the post-change scene. In three experiments, we show that people often do have a representation of some aspects of the pre-change scene even when they fail to report the change. And, in fact, they appear to "discover" this memory and can explicitly report details of a changed object in response to probing questions. The results of these real-world change detection studies are discussed in the context of broader claims about change blindness.
