Age, memory load, and individual differences in working memory as determinants of class-inclusion reasoning.

We studied the effects of individual differences in speak-span scores and variations in memory demands on the class-inclusion performance of 10-, 13-, and 15-year-old children. The speak-span task was an age-appropriate modification of Daneman and Carpenter's (1980) reading-span task and was considered to be a measure of global resources. The age variable was assumed to be a global index of skill development, and some of the specific skills hypothesized to be important in class-inclusion reasoning were estimated using a mathematical model. The results from both regression analyses and the mathematical model indicated that differences in age, speak span, and memory load all affected performance. Surprisingly, the effects of speak span and memory load were independent. However, the effects of each of these variables depended on the age level of the participants. Based on these findings, we argued that (a) resources vary continuously with age, (b) both skill level and global resources should be varied in developmental studies of problem solving, and (c) resource theories (e.g., Norman & Shallice, 1986) should be modified to account for developmental change.     

Christianity,settler colonialism,and resource extraction

This article explores the relationship between Christianity, extractivism, and Amer-European settler colonialism. It argues that Amer-European Christianity is an extractivist religion, with beliefs and practices that are deeply intertwined with an extractivist relationship to the natural world and Indigenous peoples. In conversation with the work of Willie Jennings and exploring the impact of the doctrine of Christian discovery, the extractivist theology of John Locke, and the supersessionist use of divine election and covenant, this article exemplifies how Amer-European Christianity has shaped and been shaped by settler colonial extractivism. It raises the question whether and how Amer-European settler Christians may decolonize their extractivist relationship to Indigenous peoples and the natural world by learning from Indigenous peoples in dialogue with the work of the Osage theologian “Tink” Tinker.     

Effect of brief mindfulness and relaxation inductions on anxiety,affect and brain activation in athletes

The mindfulness-based intervention and psychological skills training are often used for maintaining the mental health or reducing undesirable mental states in athletes. However, their differences in acute effects on mental health and underlying neural mechanism are not well understood. Therefore, the purpose of the current study was to examine the differential effects of brief mindfulness induction (MI) and relaxation induction (RI) on state anxiety, affect and brain activation. Thirty-five track and field athletes were recruited for this study. Using a within-subjects crossover design, participants underwent three conditions that incorporated two 30-min experimental conditions (i.e., MI or RI) and a control condition. State anxiety and affect were assessed before and after intervention, and brain activation (i.e., theta, alpha bands) were recorded by electroencephalography (EEG) during each 30-min condition. Repeated measures analysis of variance revealed that MI and RI similarly reduced state anxiety and negative affect from pre-test to post-test compared to the control condition. In terms of positive affect, there were no significant differences among the three conditions across times. Furthermore, participants exhibited higher frontal theta power during the MI and RI than control condition, whereas no differences in alpha power were observed among conditions. The current study provides initial evidence from an electrophysiological perspective that brief MI and RI both improve the negative psychological states in individual sport athletes through similar neural mechanisms. Nevertheless, the moderating effects of training experiences and long-term interventions on mental state and EEG activity in athletes need further investigation in future studies.     

Culture and collective argumentation

What are the mechanisms underlying the reproduction and change of collective beliefs? The paper suggests that a productive and promising approach for dealing with this question can be found in ontogenetic and cross-cultural studies on ‘collective argumentations and belief systems’; this is illustrated with regard to moral beliefs: After a short discussion of the rationality/relativity issue in cultural anthropology some basic elements of a conceptual framework for the empirical study of collective argumentations are outlined. A few empirical case studies are summarized; the results deliver some empirical evidence to the assumption that as the ‘logic of collective argumentations’ develops in children and adolescent there will be different and increasingly more complex constraints on the kinds of basic moral beliefs that can be collectively accepted. Most importantly, as children approach adolescence they may have acquired a ‘logic of argumentation’ which makes possible a collectively valid distinction between the ‘is’ and the ‘ought’ of some disputed particular moral issue. A comparison with a land litigation among Trobriands (Papua New Guinea) shows that the ‘logic of argumentation’ and the corresponding basic moral beliefs of Trobriands very much resemble the ‘logic of argumentation’ and moral rationality standards of (German) adolescents.     

A Study of the Ethical Dilemmas Experienced by School Psychologists in Portugal

This study examines the ethical dilemmas and difficulties encountered by Portuguese school psychologists. As part of a larger survey, participants were asked about ethical issues faced in daily practice and asked to describe ethical incidents. Of the 477 respondents, 274 reported 441 ethically troubling or challenging situations. Responses were coded into a six-category system based on the code of ethics of Portuguese psychologists. Most of the reported dilemmas concerned privacy and confidentiality principles (53%). Results are discussed in light of relevant literature and international findings. Implications for the development of the profession and future research are provided.     

Black Jack: Do company benefits and feelings have an impact on my happiness?

The aim of this study was to determine whether casino employees’ benefits and their feelings about the company influence their experienced happiness. A total of 1 502 casino employees were surveyed (females = 57%; males = 43%). They completed a company benefits, feelings and happiness questionnaire within the work context. Data were analysed to predict what company benefits and whether feelings about the company impact on the casino employees’ happiness; and also to test the mediation effects of company benefits on their happiness experienced through feelings about the company. In addition, structural relations between happiness and feelings about the company, and happiness and company benefits were tested. Findings from the regression analyses and structural equation modelling suggest that feelings about the company and company benefits such as staff meals and pension funds do predict personal happiness and positive feelings about the company where they are employed. Moreover, feelings about the company mediated the effect of stay-in facilities, staff meals and a bonus on happiness. Positive feelings about their company seem to explain employee happiness, particularly with the availability of company benefits such as stay-in facilities, staff meals and a bonus scheme.     

Difference as a Resource for Thinking: An Online Dialogue Showing the Role Played by Difference in Problem Solving and Decision Making

Contemporary societies require citizens and workers to face unexpected challenges. This calls for a shift of emphasis from individualistic competence to the importance of collective intelligence. This article describes a plan for a project in which students who are eight to twelve years old will not only realize that difference is a crucial resource in problem solving and decision making but also live out their personal value as thinking, active beings. They will participate in an online dialogue that takes place among children who attend schools in under‐resourced communities and in middle‐class and upper‐class communities. The students will work on learning units based on philosophical content designed to stimulate their critical ability. The philosophical scenarios will be related to the everyday lives of the children through concrete examples. These examples will be followed by questions that aim to promote the advancement of the students’ thinking skills.     

Trait Intellect Predicts Cognitive Engagement: Evidence from a Resource Allocation Perspective

Trait Intellect, one of the two ‘aspects’ of the broader Openness/Intellect ‘domain’, predicts performance on a range of cognitive tasks including tests of intelligence and working memory. This has been explained in terms of the tendency for high‐Intellect individuals to explore, or engage more effortfully with, abstract information. This theoretical perspective can be framed in the language of Resource Allocation Theory, in terms of high‐Intellect individuals allocating more of their available cognitive resources to abstract cognitive tasks. In two experiments (total N = 160), we examined the relation between Intellect and cognitive engagement during a primary word‐search task under conditions of both high and low secondary cognitive load. Both experiments revealed that high‐Intellect individuals were more vulnerable to the impact of the secondary cognitive load on primary task performance. This suggests that, under low secondary load, such individuals were indeed allocating more of their available cognitive resources to the primary task. These results held after controlling for trait Openness, trait Industriousness (an aspect of Conscientiousness) and a measure of working memory capacity (N‐back task). Our findings provide novel support for the cognitive mechanisms proposed to underlie trait Intellect. Copyright © 2016 European Association of Personality Psychology     

Paradigms and Personhood: A Deepening of the Dilemmas in Ethics and Medical Ethics

There are many calls for a definitions personhood, but also many logical and Wittgensteinian reasons to think fulfilling this is unimportant or impossible. I argue that we can consider many contexts as language-games and consider the person as the key player in each. We can then examine the attributes, presuppositions and implications of personhood in those contexts. I use law and therapeutic psychology as two examples of such contexts or language-games. Each correlates with one of the classic “theories” of ethics-deontology and consequentialism. But each is a large enough cluster to consider them as paradigms in a sense related to Thomas Kuhn's notion in The Structure of Scientific Revolutions. Showing the presuppositions about and “takes” on personhood together with the connections involved in the paradigms deepens the dilemmas we already know to be present.
