Meta-analysis of the relationship between risk perception and health behavior: the example of vaccination.

BACKGROUND: Risk perceptions are central to many health behavior theories. However, the relationship between risk perceptions and behavior, muddied by instances of inappropriate assessment and analysis, often looks weak. METHOD: A meta-analysis of eligible studies assessing the bivariate association between adult vaccination and perceived likelihood, susceptibility, or severity was conducted. RESULTS: Thirty-four studies met inclusion criteria (N = 15,988). Risk likelihood (pooled r = .26), susceptibility (pooled r = .24), and severity (pooled r = .16) significantly predicted vaccination behavior. The risk perception-behavior relationship was larger for studies that were prospective, had higher quality risk measures, or had unskewed risk or behavior measures. CONCLUSIONS: The consistent relationships between risk perceptions and behavior, larger than suggested by prior meta-analyses, suggest that risk perceptions are rightly placed as core concepts in theories of health behavior.     

Children’s spirituality and the practice of meditation in Irish primary schools

Abstract

This paper uses an interdisciplinary approach to explore the child’s experience of meditation in Irish primary schools and its impact on children’s spirituality. Using a phenomenological, hermeneutic, mystagogical methodology, it describes how children experience the practice of meditation, the benefits they consider they gain from it and the nature of its impact, if any, on their spirituality. Seventy children, aged 7 to 11, were interviewed. The study is original in that the interview protocol contained novel processes designed to elicit from children their experience, if any, of the transcendent in meditation and in its depth of analysis of the spiritual fruits of the practice. The study concludes that meditation does have the capacity to nourish the innate spirituality of the child. It offers a heuristic model outlining the key elements of the child’s experience of meditation, stresses the importance of personal spiritual experience and supports the introduction of meditation in primary schools.     

Generating consensus priority interval vectors for group decision‐making in the AHP

Many practical and important decision‐making problems are complicated by at least two factors: (1) the qualitative/subjective nature of some criteria often results in uncertainty in the individual ratings; and (2) group decision‐making is involved and some means of aggregating individual ratings is required. Traditionally, both individual and group priorities have been represented as point estimates, but this approach presents severe limitations for accommodating imprecision in the decision‐making process. This paper examines the group decision‐making problem in the context where priorities are represented as numeric intervals. A set of techniques that could be used at some of the phases of an analytic hierarchy process (AHP)‐based group decision‐making process, which has the objective of generating a ‘consensus’ priority that represents the group's opinion with regards to the relative importance of a set of N objects (e.g. criteria, alternatives), is presented.

The effect of long-term working memory through personalization applied to free recall: Uncurbing the primacy-effect enthusiasm

In this study, a personalization method (Guida, Tardieu, & Nicolas, European Journal of Cognitive Psychology, 21: 862–896 2009) was applied to a free-recall task. Fifteen pairs of words, composed of an object and a location, were presented to 93 participants, who had to mentally associate each pair and subsequently recall the objects. A 30-s delay was introduced on half of the trials, the presentation rate was manipulated (5 or 10 s per item), and verbal and visuospatial working memory tests were administered to test for their effects on the serial curve. Two groups were constituted: a personalized group, for whom the locations were well-known places on their university campus, and a nonpersonalized group, for whom the locations did not refer to known places. Since personalization putatively operationalizes long-term working memory (Ericsson & Kintsch, Psychological Review, 102: 211–245 1995)—namely, the capacity to store information reliably and rapidly in long-term memory—and if we take a dual-store approach to memory, the personalization advantage would be expected to be greater for pre-recency than for recency items. Overall, the results were compatible with long-term working memory theory. They contribute to validating the personalization method as a methodology to characterize the contribution of long-term memory storage to performance in working memory tasks.     

Improving the Performance of Failing Students by Overcoming Their Self-Serving Attributional Biases

The causal impact of attributions on academic performance was examined by changing low-scoring students' attributions regarding their poor performances. Initially, when students who were failing a college course identified the cause of the performance, they emphasized external, uncontrollable causes. Because these self-serving attributions could have perpetuated poor performance on subsequent examinations, students in the experimental condition were exposed to information that suggested that grades in college are caused by internal, controllable factors such as effort and motivation. As predicted, on subsequent tests and on the final examination, these students earned higher grades than control students who received no attributional information. These findings lend support to an attributional model of academic achievement and also suggest that educational interventions that shift attributions away from a self-serving pattern to a performance-facilitating pattern may improve academic outcomes.
