Spirituality and the Self

Spirituality and the Self explores how a mystical experience playing basketball led to a metamorphosis that transformed, expanded and unbound the author's sense of self.     

Temporal dynamics in attention bias: effects of sex differences,task timing parameters,and stimulus valence

New methods of calculating indices from the dot-probe task measure temporal dynamics in attention bias or fluctuations in attention bias towards and away from emotional stimuli over time. However, it is unclear how task-specific parameters such as stimulus valence and stimulus onset asynchrony (SOA) as well as participant sex affect temporal dynamics in attention bias. To address this, male and female participants (N?=?106) completed either a fearful or happy face dot-probe task with four levels of SOA (84?ms, 168?ms, 336?ms, and 672?ms). Results suggest that temporal dynamics in attention bias are (1) greatest at the longest SOA, (2) greater in females, and (3) insensitive to stimulus valence. These findings indicate that participant sex and task timing, but not stimulus valence, are related to temporal dynamics in attention bias and should be considered in future studies utilizing this approach.     

Parents’ perceptions of children’s executive functions across different cities

Culture is thought to strongly influence the development of executive functions (EF), such that ethnic groups with similar cultural origins are generally assumed to exhibit comparable levels of EF performance. However, other characteristics, such as urbanization and Westernization, may also affect EF performance in societies comprising different ethnic groups, even if the ethnic groups share a similar cultural origin. The present study aimed to compare the perceptions of parents in three cities [China–Shenzhen (ZH group), China–Hong Kong (HK group), and Singapore (SG group)] regarding the EF performances of their children, all of whom share the same genetic and cultural (i.e., Chinese) origin. The study recruited 95 children aged 5–6 years (ZH group = 32; HK group = 32; SG group = 31). Their parents were invited to complete the Behavior Rating Inventory of Executive Function (BRIEF). The ZH group had significantly lower BRIEF scores compared to both the HK and SG groups. However, the BRIEF scores of the HK and SG groups only differed significantly in terms of the Organization of Materials domain. The results suggest city-related differences in parents’ perceptions of their children’s EF performances, despite their similar genetic and cultural backgrounds. We additionally discuss further interpretations of our results and the limitations of this study.     

Social intelligence and interview accuracy: Individual differences in the ability to construct interviews and rate accurately

This research examined differences in interviewers’ ability to identify effective interview questions and to accurately rate interviewees’ responses. Given the theoretical association between these interview activities and the construct of social intelligence (SI), a performance‐based measure of SI was developed utilizing situational judgment test methodology. The initial step was to examine evidence of the psychometric properties and construct validity of the new SI measure. The SI measure, a test of general mental ability (GMA), and a personality inventory were then used to examine aspects of rater performance. Participants chose a set of interview questions and viewed interviewee responses during a videotaped interview. Results showed that people higher in SI and GMA chose interview questions judged by experts to be superior and were more accurate in rating interviewee responses. The SI measure explained variance beyond GMA and outperformed a trait‐based SI measure. Implications for the selection and training of interviewers are discussed.     

What’s Wrong with the Scrum Laws in Rugby Union? — Judgment,Truth and Refereeing

Officiating and the role of officials in sport is are crucial and often decisive factors in sports contests. Justice and desert of sport contests, in part, rely on officiating truths (performances) that arise from an appropriate admixture of epistemic (judgements) and metaphysical (actions) ingredients. This paper provides a rigorous and original philosophical analysis of the problems of obeying and applying the rules of sport. The paper focuses on a the scrum in rugby union. The scrum has become a focus of criticism and bewilderment. Elite rugby is damaged as a spectacle because too much time is wasted setting and re-setting scrums. Furthermore, trust in the fairness of games is eroded because the scrum is a ‘lottery’. In this paper, we identify two fundamental structural problems which contribute to the scrum controversy. First, we argue that officials cannot make reliable judgements about scrums because they cannot see what they need to see. Secondly, we argue that players cannot follow the laws of the scrum even if they have a strong desire to do so. Consequently, the scrum is not only potentially dangerous, but also flawed in terms of its capacity to actualise an intended part of the game.     

RULE-CIRCULARITY AND THE JUSTIFICATION OF DEDUCTION

I examine Paul Boghossian's recent attempt to argue for scepticism about logical rules. I argue that certain rule-and proof-theoretic considerations can avert such scepticism. Boghossian's 'Tonk Argument' seeks to justify the rule of tonk-introduction by using the rule itself. The argument is subjected here to more detailed proof-theoretic scrutiny than Boghossian undertook. Its sole axiom, the so-called Meaning Postulate for tonk, is shown to be false or devoid of content. It is also shown that the rules of Disquotation and of Semantic Ascent cannot be derived for sentences with tonk dominant. These considerations deprive Boghossian's scepticism of its support.     

Exchange relationships: examining psychological contracts and perceived organizational support

The authors surveyed 347 public sector employees on 4 measurement occasions to investigate the conceptual distinctiveness of the psychological contract and perceived organizational support (POS) and how they are associated over time. Results support the distinctiveness of the 2 concepts. In terms of their interrelationships over time, by drawing on psychological contract theory the authors found little support for a reciprocal relationship between POS and psychological contract fulfillment. Under an alternative set of hypotheses, by drawing on organizational support theory and by separating psychological contract fulfillment into its 2 components (perceived employer obligations and inducements), the authors found that perceived employer inducements were positively related to POS, which, in turn, was negatively related to perceived employer obligations. The results suggest that POS and the components of psychological contract fulfillment are more important in predicting organizational citizenship behavior than psychological contract fulfillment.     

Approximate optimal control as a model for motor learning

Current models of psychological development rely heavily on connectionist models that use supervised learning. These models adapt network weights when the network output does not match the target outputs computed by some agent. The authors present a model of motor learning in which the child uses exploration to discover appropriate ways of responding. The model is consistent with what is known about how neural systems evaluate behavior. The authors model the development of reaching and investigate N. Bernstein's (1967) hypotheses about early motor learning. Simulations show the course of learning as well as model the kinematics of reaching by a dynamical arm.     

Evidence for a gene-environment interaction in predicting behavioral inhibition in middle childhood

Gene-environment interactions are presumed to shape human behavior during early development. However, no human research has demonstrated that such interactions lead to stable individual differences in fear responses. We tested this possibility by focusing on a polymorphism in the promoter region of the gene for the serotonin transporter (5-HTT). This polymorphism has been linked to many indices of serotonin activity. Specifically, we tested the hypothesis that an interaction between children's 5-HTT status and maternal reports of social support predicts inhibited behavior with unfamiliar peers in middle childhood. Results were consistent with this hypothesis: Children with the combination of the short 5-HTT allele and low social support had increased risk for behavioral inhibition in middle childhood.
