Maximum-corrected and chance-corrected measures of effect size for the Mantel-Haenszel test

Two measures of effect size are described for the Mantel-Haenszel test. Both measures belong to the r-family of effect size measures. One measure is based on a maximum-corrected model, and the second measure is based on a chance-corrected model.     

Sport psychologists' perceptions of sport and mental health practitioners

Abstract

This study surveys recently graduated sport psychology (SP) doctoral students' (N = 34) educational backgrounds, work experiences, and perceptions of the professional field of SP inside and outside the realm of academia. Special attention was given to subjects' perceptions and expectations with regard to applied work in SP, actual work experiences, and income. Findings indicate that almost all graduates are spending their time in a variety of work activities, i.e., some combination of teaching, research, consulting, administration, and coaching, with a strong emphasis on teaching in an academic institution. Gender analysis revealed that, in general, females earned 74% of what males earned; females earned 53% of what males earned outside academia. Graduates' personal comments suggest a concern about consumer demand and financial support offered applied professionals in SP as well as the adequacy of their own training to provide applied services. Implications for AAASP and SP program directors are provided.     

Mad Scientists, Narrative, and Social Power: A Collaborative Learning Activity

Nathaniel Hawthorne’s short stories “The Birthmark” (1843) and “Rappaccini’s Daughter” (1844) encourage critical thinking about science and scientific research as forms of social power. In this collaborative activity, students work in small groups to discuss the ways in which these stories address questions of human experimentation, gender, manipulation of bodies, and the role of narrative in mediating perceptions about bodies. Students collectively adduce textual evidence from the stories to construct claims and present a mini-argument to the class, thereby strengthening their skills in communication and cooperative interpretation of ethical dilemmas. This exercise is adaptable to shorter and longer periods of instruction, and it is ideal for instructors who collaborate across areas of expertise.     

The Effects of Religiosity on Preferences and Expectations for Marital Therapy Among Married Christians

Highly religious couples constitute a substantial portion of marital therapy clients in the U.S. Married Christian individuals ( N = 211) completed a survey of demographics and religiosity (religious values and Christian beliefs). They rated preferences and expectations for one of four marital therapy situations: Christian therapist using Christian practices (e.g., prayer or reference to Scripture), Christian therapist using psychological practices only, non-Christian therapist willing to use Christian practices, and non-Christian therapist using psychological practices only. High religious values and high Christian beliefs predicted ratings of marital therapy situations, where high was defined as one standard deviation above the mean of standardized norm groups. Low to moderate religious values or Christian beliefs did not predict ratings of marital therapy. It was concluded that highly religious couples present a special situation where the marketing, assessment, and practice of marital therapy might differ from therapy with other types of couples.     

Gaze bias: Selective encoding and liking effects

People look longer at things that they choose than things they do not choose. How much of this tendency—the gaze bias effect—is due to a liking effect compared to the information encoding aspect of the decision-making process? Do these processes compete under certain conditions? We monitored eye movements during a visual decision-making task with four decision prompts: Like, dislike, older, and newer. The gaze bias effect was present during the first dwell in all conditions except the dislike condition, when the preference to look at the liked item and the goal to identify the disliked item compete. Colour content (whether a photograph was colour or black-and-white), not decision type, influenced the gaze bias effect in the older/newer decisions because colour is a relevant feature for such decisions. These interactions appear early in the eye movement record, indicating that gaze bias is influenced during information encoding.     

Risk,religiosity, and emerging adulthood: description of Christian,Jewish, and Muslim university students at entering the freshman year

American students transitioning to university are at an increased risk for behaviours such as binge drinking, depression and suicidality. Despite the proliferation of prevention and intervention programs, rates remain high. Although religiosity is known to confer a protective effect in this population, it remains largely untapped as a resource because, among other reasons, it is poorly understood, poses ethical challenges, and exposes areas of distrust between the religious and medical establishments. This report describes the findings of a survey that examined possible factors explaining the relationship between religiosity, risky behaviours and emotional extremes in students as they transitioned into their first year of university. This study accounted for the religious diversity of the US by surveying Christian, Jewish, Muslim and religiously unaffiliated students. Findings indicated that religiosity was consistently and negatively correlated to risky behaviours across all faith groups. Interestingly, unique patterns in levels of religiosity emerged among the various faith groups. Similarly, patterns of engagement in risky behaviours demonstrated variation among religious groups. Our findings add to the body of evidence that suggests university-based professionals take into consideration student religiosity when creating prevention intervention programs for students.     

Implicit and explicit processes in a second-language learning task

Abstract

Two experiments examined the learning of a set of Greek pronunciation rules through explicit and implicit modes of rule presentation. Experiment 1 compared the effectiveness of implicit and explicit modes of presentation in two modalities, visual and auditory. Subjects in the explicit or rule group were presented with the rule set, and those in the implicit or natural group were shown a set of Greek words, composed of letters from the rule set, linked to their pronunciations. Subjects learned the Greek words to criterion and were then given a series of tests which aimed to tap different types of knowledge. The results showed an advantage of explicit study of the rules. In addition, an interaction was found between mode of presentation and modality. Explicit instruction was more effective in the visual than in the auditory modality, whereas there was no modality effect for implicit instruction. Experiment 2 examined a possible reason for the advantage of the rule groups by comparing different combinations of explicit and implicit presentation in the study and learning phases. The results suggested that explicit presentation of the rules is only beneficial when it is followed by practice at applying them.     

Cognitive Offloading: Structuring the Environment to Improve Children's Working Memory Task Performance

Research has shown that adults can engage in cognitive offloading, whereby internal processes are offloaded onto the environment to help task performance. Here, we investigate an application of this approach with children, in particular children with poor working memory. Participants were required to remember and recall sequences of colors by placing colored blocks in the correct serial order. In one condition the blocks were arranged to facilitate cognitive offloading (i.e., grouped by color), whereas in the other condition they were arranged randomly. Across two experiments (total N = 166) the ordered condition improved task performance for children with low working memory ability. In addition, participants in Experiment 2 rated the difficulty of the two arrangements and performed a further condition in which they were given an opportunity to freely arrange the blocks before completing the task. Despite performing better in the ordered condition, children with low working memory ability did not rate the ordered arrangement as easier, nor did they choose an ordered arrangement when given the opportunity to do so. This research shows that cognitive offloading can also be a useful process in populations other than typical adults, and the implications of this work for supporting children with poor working memory are discussed.
