Mathematical symbols as epistemic actions

Recent experimental evidence from developmental psychology and cognitive neuroscience indicates that humans are equipped with unlearned elementary mathematical skills. However, formal mathematics has properties that cannot be reduced to these elementary cognitive capacities. The question then arises how human beings cognitively deal with more advanced mathematical ideas. This paper draws on the extended mind thesis to suggest that mathematical symbols enable us to delegate some mathematical operations to the external environment. In this view, mathematical symbols are not only used to express mathematical concepts??they are constitutive of the mathematical concepts themselves. Mathematical symbols are epistemic actions, because they enable us to represent concepts that are literally unthinkable with our bare brains. Using case-studies from the history of mathematics and from educational psychology, we argue for an intimate relationship between mathematical symbols and mathematical cognition.     

Memory as discrimination: What distraction reveals

Recalling information involves the process of discriminating between relevant and irrelevant information stored in memory. Not infrequently, the relevant information needs to be selected from among a series of related possibilities. This is likely to be particularly problematic when the irrelevant possibilities not only are temporally or contextually appropriate, but also overlap semantically with the target or targets. Here, we investigate the extent to which purely perceptual features that discriminate between irrelevant and target material can be used to overcome the negative impact of contextual and semantic relatedness. Adopting a distraction paradigm, it is demonstrated that when distractors are interleaved with targets presented either visually (Experiment 1) or auditorily (Experiment 2), a within-modality semantic distraction effect occurs; semantically related distractors impact upon recall more than do unrelated distractors. In the semantically related condition, the number of intrusions in recall is reduced, while the number of correctly recalled targets is simultaneously increased by the presence of perceptual cues to relevance (color features in Experiment 1 or speaker’s gender in Experiment 2). However, as is demonstrated in Experiment 3, even presenting semantically related distractors in a language and a sensory modality (spoken Welsh) distinct from that of the targets (visual English) is insufficient to eliminate false recalls completely or to restore correct recall to levels seen with unrelated distractors . Together, the study shows how semantic and nonsemantic discriminability shape patterns of both erroneous and correct recall.     

Behavioral control of exercise in adults: Studies 7 and 8

Abstract

Building on our previous six study series, the current studies 7 and 8 evaluated behavioral methods of improving adherence to exercise in adults. The studies tested the effectiveness of a single exercise modality versus choice of a variety of exercises and were conducted as part of a 12-week extended studies college course in San Diego, CA. Recruitment efforts were targeted to individuals who reported that they were sedentary and/or had experienced difficulty adhering to regular exercise. Participants were 42 adults (32F, 10M; mean age = 42.0) in Study 7 and 48 adults (35F, 8M; mean age = 47.9) in Study 8. In each study, subjects were randomly assigned to a single focus or variety exercise condition. There were no significant group differences in class attendance or out-of-class exercise adherence rates in Studies 7 or 8. In Study 7, significantly lower drop-out rates were detected in the single focus group (19%) than the variety condition (47.6%) (p = 0.04). No significant group differences were detected for drop-out rates in Study 8. Suggestions for further research are offered.     

A Cross-Country Evaluation of Cheating in Academia—A Comparison of Data from the US and the Czech Republic

In this study, we examine differences in cheating behaviors in higher education between two countries, namely the United States and the Czech Republic, which differ in many social, cultural and political aspects. We compare a recent (2011) Czech Republic survey of 291 students to that of 268 students in the US (Klein et al., 2007). For all items surveyed, CR students showed a higher propensity to engage in cheating. Additionally, we found more forms of serious cheating present in the Czech sample. In all cases, the differences between the US and Czech samples were statistically significant.     

Surviving and Thriving in a Secularized Culture: The Phenomenon of Religious (Church/Faith) Schools in England

While the mainstream churches are being increasingly ignored as religious institutions in rapidly secularizing England, their schools survive and, in many instances, thrive. These schools, financed by public funds, are an increasingly important part of the English state schooling system. It would appear that their survival and expansion has been driven by increased societal emphasis on academic success, which, in the main, these schools provide. What are the implications of this in terms of social divisiveness and what is the response of the churches themselves in terms of their role in the communities they serve? While the arguments for and against are entered into by a small number of commentators, it is perhaps significant that the once politically sensitive area of church/faith schools is still left alone by politicians.     

Personal Constructs of Mind-Body Identity in People Who Experience Medically Unexplained Symptoms

“Medically unexplained symptoms” (MUS) refers to chronic physical symptoms without a clear medical cause, which produce significant levels of distress and functional impairment. This project modified the repertory grid technique to explore how twenty participants experiencing MUS construed self and others in bodily and psychological ways. Findings suggested that symptoms are well integrated within participants' wider mind–body construct systems. Increased distance between how self in general is construed compared to self when symptoms are worst was associated with reduced anxiety. Measuring intrapersonal and interpersonal implicative dilemmas suggested that moral and relational construing of identity is affected by MUS.     

Intraindividual models of employee well-being: What have we learned and where do we go from here?

As societal concern shifts from financial survival towards quality of life issues, both in and outside of the workplace, scholarly interest in employee well-being too has risen greatly in recent years. This greater attention to the antecedents and outcomes of employee well-being, such as job satisfaction, work engagement, and job burnout amongst others, is reflected in the proliferation of theories, constructs, and studies seeking to describe and explain why employees flourish or become exhausted at work, and the effect of employee well-being on individual behaviours and the organization at large. In this article, we provide a selective review of the current state of research in employee well-being, as well as key theories that have been employed in its study, with the aim of providing a critical assessment of the current state of employee well-being research as well as suggest future directions for the field. In particular, we discuss how research adopting intraindividual perspectives in the study of employee well-being can not only add value to our understanding of well-being but also complement the findings from between-individual studies, and offer suggestions for the development of a comprehensive theoretical model that integrates the two perspectives.
