This article reports on some findings of a small research project that examined the role of meditation in enhancing the relational lives of children, in particular, their relationship with God. It begins by discussing the literature on relevant research studies that investigate different aspects of meditation. The research method in the project was a case study that involved one Catholic primary school in the Melbourne Archdiocese. Different data collecting strategies were utilised, and this article presents and discusses the analysis and findings from one data source – the analysis and interpretation of a drawing activity which was designed to follow one of the weekly meditation exercises that had been observed by the researchers. Finally, the implications of the findings for education and, in particular, religious education are presented.  相似文献

In this study, we investigated the time course of attentional bias for threat-related (angry) facial expressions under conditions of high versus low cognitive (working memory) load. Event-related potential (ERP) and reaction time (RT) data were recorded while participants viewed pairs of faces (angry paired with neutral face) displayed for 500 ms and followed by a probe. Participants were required to respond to the probe while performing a concurrent task of holding in working memory a sequence of digits that were either in the same order (low memory load) or in a random mixed order (high memory load). The ERP results revealed that higher working memory load resulted in enhanced lateralized neural responses to threatening relative to neutral faces, consistent with greater initial orienting of attention to threatening faces (early N2pc: 180–252 ms) and enhanced maintenance of processing representations of threat (late N2pc, 252–320 ms; SPCN, 320–500 ms). The ERP indices showed significant positive relationships with each other, and also with the behavioral index of attentional bias to threat (reflected by faster RTs to probes replacing angry than neutral faces at 500 ms), although the latter index was not significantly influenced by memory load. Overall, the findings indicate that depletion of cognitive control resources, using a working memory manipulation, increases the capacity of task-irrelevant threat cues to capture and hold attention.  相似文献

The purpose of this study was to assess the relationship between the recall of a highly salient remote event, the terrorist attack in New York City on 9/11/01, and general cognitive functioning in the elderly. A heterogeneous group (n = 93) of persons ≥65 years of age (M = 76.5, SD = 6.4), from both community and hospital settings, were asked to describe as much as they could remember about the events of 9/11/01 in New York City. The number of correct factual details, affective or emotional responses, and incorrect details were recorded. Ten multiple choice questions were then administered to assess recognition of the 9/11 events (M = 9.1 items correct, SD = 1.2). The mini mental state exam (MMSE) was also administered (M = 26.3, SD = 3.4). Participants generated a mean of 4.8 (SD = 3) correct factual details about 9/11, 1.1 affective/emotional responses (SD = 1.1), and 0.22 incorrect recollections (SD = 0.46). Significant correlations (p &;lt; .01) were found between correct details recalled and the MMSE (0.42), education (0.37), and age (?0.31). A significant negative correlation (p &;lt; .01) was found between incorrect details recalled and MMSE scores (?0.38). Female participants generated significantly more affective responses than males (M = 1.3 vs. 0.51; p &;lt; .001) but recall of correct details was equivalent. The recall of 9/11 events, approximately 18 months after the incident, appears related to general mental status, education, and age. Responses to this question may be helpful in assessing the mental status of the elderly. In addition, now that objective memory data has been established, recall of this event by other samples of seniors can be monitored over time to determine the cognitive processes related to the storage and retrieval of this unique and tragic event.  相似文献

The study investigated attentional biases for pictorial and linguistic health‐threat stimuli in high and low health anxious individuals, who were selected from the upper and lower quartile ranges of a normal sample using a screening measure of health anxiety. Attentional bias was assessed using a visual probe task which presented health‐threat and neutral pictures and words at two exposure durations, 500 ms and 1250 ms. The prediction that the high health anxious group would show a greater attentional bias for health‐threat cues than the low health anxious group was not supported despite the groups being well‐differentiated on a general measure of health anxiety, the Illness Attitudes Scale (IAS). Instead, the results indicated that individuals with high levels of anxiety sensitivity showed a significantly greater initial attentional bias for threat pictures compared with those with low anxiety sensitivity, as assessed by the Anxiety Sensitivity Index (ASI).  相似文献

Ellis and Beaton (1993a) reported that the keyword method of learning enhanced memory of foreign vocabulary items when receptive learning was measured. However, for productive learning, rote repetition was superior to the keyword method. The first two experiments reported here show that, in comparison with rote repetition, both receptive and productive learning can be enhanced by the keyword method, provided that the quality of the keyword images is adequate. In a third experiment using a subset of words from Ellis and Beaton (1993a), the finding they reported, that for productive learning rote repetition was superior to the keyword method, was reversed. The quality of keyword images will vary from study to study and any generalisation regarding the efficacy of the keyword method must take this into account.  相似文献

This longitudinal study investigated differences in beliefs and perceived behavioural control between smokers and non-smokers in a large sample of adolescents. Positive and negative instrumental beliefs, normative beliefs, perceived behavioural control (PBC) and smoking status were assessed in the same participants at 11, 13 and 15 years of age. Prospective analyses among non-smokers revealed that for boys, negative instrumental beliefs in non-smokers at age 11 predicted smoking at age 15 years. For girls, normative beliefs and PBC in non-smokers at age 11 predicted smoking status at age 13; normative beliefs at age 11 predicted smoking at age 15; and positive instrumental beliefs and normative beliefs at age 13 predicted smoking status at age 15. Cross-sectional data revealed that smokers were significantly more likely than non-smokers to endorse positive instrumental beliefs, less likely to agree with negative instrumental belief items, more likely than non-smokers to perceive social pressure to smoke, and less likely to report control over smoking, and that female smokers reported less control over smoking and fewer negative instrumental beliefs than all other groups including male smokers at age 13. The need for belief-based preventative interventions that are age- and gender-relevant is discussed.  相似文献

Interpersonal theory identifies agency and communion as uncorrelated (orthogonal) dimensions, largely evidenced by research examining between-person analyses of single-occasion measures. However, longitudinal studies of interpersonal behavior demonstrated the within-person association of agency and communion is not orthogonal for many individuals, and between-person differences in these associations relate to adjustment. We applied a similar approach to investigate the association of interpersonal perceptions. 184 university students completed a 7-day event-contingent study of their interpersonal experiences. Using multilevel regression models, we demonstrated that agentic and communal perceptions were positively associated, and the strength of this within-person association was moderated by between-person scores of dependency and narcissism. We discuss the benefits of incorporating within-person interpersonal associations (termed interpersonal covariation) into interpersonal theory and assessment.  相似文献

It is controversial whether Wittgenstein's philosophy of mathematics is of critical importance for mathematical proofs, or is only concerned with the adequate philosophical interpretation of mathematics. Wittgenstein's remarks on the infinity of prime numbers provide a helpful example which will be used to clarify this question. His antiplatonistic view of mathematics contradicts the widespread understanding of proofs as logical derivations from a set of axioms or assumptions. Wittgenstein's critique of traditional proofs of the infinity of prime numbers, specifically those of Euler and Euclid, not only offers philosophical insight but also suggests substantive improvements. A careful examination of his comments leads to a deeper understanding of what proves the infinity of primes.  相似文献

Rapid online control during reaching has an important bearing on movement accuracy and flexibility. It is surprising then that few studies have investigated the development of rapid online control in children. In this study, we were particularly interested in age-related changes in the nature of motor control in response to visual perturbation. We compared the performance of younger (6–7 years of age), mid-aged (8–9), and older (10–12) children, as well as healthy young adults using a double-step reaching task. Participants were required to make target-directed reaching movements in near space, while also responding to visual perturbations that occurred at movement onset for a small percentage of trials. Results showed that both the older and mid-aged children corrected their reaching in response to the unexpected shifts in target location significantly faster than younger children, manifest by reduced time to correction. In turn, the responses of adults were faster than older children in terms of movement time and on kinematic measures such as time to correction and time to peak velocity. These results indicate that the capacity to utilize forward estimates of limb position in the service of online control of early perturbations to ballistic (or rapid) reaching develops in a non-linear fashion, progressing rapidly between early and middle childhood, showing a degree of stability over mid and later childhood, but then evidence for continued refinement between childhood and young adulthood. The pattern of change after childhood and into early adolescence requires further investigation, particularly during the rapid phase of physical growth that accompanies puberty.  相似文献
