CHANCE AND NECESSITY IN ARTHUR PEACOCKE'S SCIENTIFIC WORK

Arthur Peacocke was one of the most important scholars to contribute to the modern dialogue on science and religion, and for this he is remembered in the science‐religion community. Many people, however, are unaware of his exceptional career as a biochemist prior to his decision to pursue a life working as a clergyman in the Church of England. His contributions to studies of deoxyribonucleic acid (DNA) structure, effects of radiation damage on DNA, and on the interactions of DNA and proteins are among the most important in the field at the time and have had a lasting scientific impact that is still felt today. Peacocke's arguments with Jacques Monod over stochastic (chance) and deterministic (necessity) processes driving evolution became important independently for both the science and the religion communities and appear to have contributed significantly to his decision to become involved in science‐religion dialogue rather than continuing his work exclusively in the field of science. Nevertheless, although Peacocke took on an active church life and ceased his experimental work, he never left science but continued to read the scientific literature and published a scientific review on different approaches in defining DNA structure as recently as 2005.     

The pedagogical imperative of values education

Recent research has exposed the potential of quality teaching to exercise a positive influence on student achievement. Extending beyond surface and factual learning, quality teaching has posited conceptions of ‘intellectual depth’, ‘communicative competence’ and ‘self‐reflection’ as being central to effective learning. Implicit in these conceptions are values dimensions reflected in notions of positive relationships, the centrality of student welfare, school coherence, ambience and organisation. The influences of these on student learning, welfare and progress have been observed across public, private and religious sectors, thus confirming earlier studies of similar phenomena in religious schools. Evidence from the Australian Government's Values Education Good Practice Schools Project indicates the benefit to all schools of reflecting on, re‐evaluating and rethinking the implications of values education for curricula, classroom management and school ethos in the interests of student wellbeing and progress. This indicates a pedagogical imperative for values education which extends beyond boundaries of personal or systemic interests and ideologies.     

Investigating sustained attention ability in the elderly by using two different approaches: Inhibiting ongoing behavior versus responding on rare occasions

Previous studies on sustained attention ability in the elderly produced inconsistent results. The aim of this study was to evaluate sustained attention performance in younger and older individuals by using, in a within-subjects design, two versions of the same task (the sustained attention to response task, SART) in which only in the response mode differed: in a traditionally formatted task (TFT), subjects had to respond to rare targets, and in a Go/No-Go task they had to withhold response to rare targets. Results showed that in the TFT SART only the older group exhibited a vigilance decrement. On the contrary, only young individuals showed a vigilance decrement in the Go/No-Go SART. These results showed that older individuals, who also reported less mind wandering and a higher level of motivation, exhibited preserved sustained attention ability in the Go/No-Go SART, which could be explained by increased engagement of cognitive control mechanisms in this population. The discrepancy in performance depending on the approach used also underlines the need for further studies on the nature of attention failures and their underlying mechanisms.     

Association between individual differences in non-symbolic number acuity and math performance: A meta-analysis

Many recent studies have examined the association between number acuity, which is the ability to rapidly and non-symbolically estimate the quantity of items appearing in a scene, and symbolic math performance. However, various contradictory results have been reported. To comprehensively evaluate the association between number acuity and symbolic math performance, we conduct a meta-analysis to synthesize the results observed in previous studies. First, a meta-analysis of cross-sectional studies (36 samples, N = 4705) revealed a significant positive correlation between these skills (r = 0.20, 95% CI = [0.14, 0.26]); the association remained after considering other potential moderators (e.g., whether general cognitive abilities were controlled). Moreover, a meta-analysis of longitudinal studies revealed 1) that number acuity may prospectively predict later math performance (r = 0.24, 95% CI = [0.11, 0.37]; 6 samples) and 2) that number acuity is retrospectively correlated to early math performance as well (r = 0.17, 95% CI = [0.07, 0.26]; 5 samples). In summary, these pieces of evidence demonstrate a moderate but statistically significant association between number acuity and math performance. Based on the estimated effect sizes, power analyses were conducted, which suggested that many previous studies were underpowered due to small sample sizes. This may account for the disparity between findings in the literature, at least in part. Finally, the theoretical and practical implications of our meta-analytic findings are presented, and future research questions are discussed.     

Learning a keying sequence you never executed: Evidence for independent associative and motor chunk learning

A substantial amount of research has addressed how people learn and control movement sequences. Recent results suggested that practice with discrete key pressing sequences results in two types of sequence learning: associative learning and motor chunk development (Verwey & Abrahamse, 2012). In the present study, we addressed whether in keying sequences of limited length associative learning develops also when the use of the chunking mode is prevented by introducing during practice random deviants. In line with the notion of two different learning mechanisms, the present results indicate that associative sequence learning develops when motor chunks cannot be developed during practice. This confirms the notion that motor chunks do not rely on these associations. In addition, experience with a particular execution mode during the practice phase seems to benefit subsequent use of that mode with unfamiliar and random sequences. Also, participants with substantial video-gaming experience were faster in executing discrete keying sequences in the chunking mode. These last two results may point to the development of a general ability to produce movement sequences in the chunking mode.     

Garner interference and temporal information processing

The aim of the study was to explore whether temporal information processing can interfere with performance of a non-temporal task. A new methodology based on the Garner paradigm was employed. Participants were asked to classify two-dimensional stimuli according to either length or duration, with and without variation in the other (task-irrelevant) dimension. Garner interference was detected only with respect to classification by length when irrelevant variation in duration was present. Stroop interference was detected only in classification by length across compatible and non-compatible values of length and duration. Classification by length took more time when done with variation in duration than when duration was constant. Classification by length also took more time when length and duration were not compatible than when they were compatible. The findings indicate that the processing of duration is similar to the processing of other perceptual dimensions. The processing of duration consumes attentional resources and can interfere with the processing of other perceptual dimensions. The findings support attentional models of prospective duration judgment.     

Global VOR gain adaptation during near fixation to foveal targets

Long-term rotational vestibulo-ocular (VOR) adaptation occurs during systematic dysmetria between visual and vestibular afferents, adjusting eye-rotation angular velocity to re-establish retinal stability of the visual field. Due to translational motion of the eyes during head rotation, VOR gain is higher when fixating near objects. The current study measures VOR in humans before and after 6 min of exposure to a foveal near-target during sinusoidal whole-body rotation at 0.45 Hz. All of six participants showed post-exposure increases in open-loop VOR gain after fixating near targets, demonstrating a mean modulation increase of open-loop VOR gain from 0.86 before adaptation to 1.2 after adaptation. We discuss a number of theoretical and applied implications.     

Asymmetric dominance and phantom decoy effects in games

In individual choices between alternatives x and y, the availability of a third alternative z, judged inferior to x but not to y, tends to increase preferences for x. Two experiments investigated corresponding strategic asymmetric dominance effects in games. In Experiment 1, 72 players chose strategies in six symmetric 3 × 3 games, each having one strategy dominating just one other, or in reduced 2 × 2 games constructed by deleting the dominated strategies. Asymmetrically dominated strategies, even when unavailable (phantom decoy), increased choices of the strategies that dominated them and bolstered decision confidence. In Experiment 2, 81 participants played 12 similar but asymmetric games with or without dominated strategies, and similar asymmetric dominance, phantom decoy, and confidence effects were found.     

Last night I had the strangest dream: Varieties of rational thought processes in dream reports

From the neurophysiological perspective, thinking in dreaming and the quality of dream thought have been considered hallucinatory, bizarre, illogical, improbable, or even impossible. This empirical phenomenological research concentrates on testing whether dream thought can be defined as rational in the sense of an intervening mental process between sensory perception and the creation of meaning, leading to a conclusion or to taking action. From 10 individual dream journals of male participants aged 22–59 years and female participants aged 25–49 years, we delimited four dreams per journal and randomly selected five thought units from each dream for scoring. The units provided a base for testing a hypothesis that the thought processes of dream construction are rational. The results support the hypothesis and demonstrate that eight fundamental rational thought processes can be applied to the dreaming process.     

The Adjustment Process of Ex-Buddhist Monks to Life After the Monastery

This study explores the adjustment process of five Western ex-Buddhist monks to life after the monastery, using an in depth case study approach and thematic analysis. Participants discussed their initial experience of leaving, the process of creating a new life and their relationship with the past. The findings indicated that while each case was unique, significant common themes emerged as features of the adjustment process. The adjustment had been multi-dimensional, challenging, difficult, confusing, complex and profound for the participants. They had to contend with issues of grief, delayed development, missing out on life experiences, difficulties with intimacy, money, identity, depression, anxiety and confusion. This was combined with the hope and promise of many newly found freedoms involved in establishing a new life and identity. Parallels are drawn to the experience of Catholic priests and nuns who have departed their Orders, Vietnam veterans, ex-cult members and individuals who have left total institutions where their identity and daily lives were highly prescribed. The adjustment experience of ex-Buddhist monks extends the literature on Buddhist monks and provides an example of a life transition of interest to the helping professions because of its potential relevance to a range of major transitions for which clients may seek assistance.
