The learning and motor development transfer process

The aim of this study is to analyze the transference process in motor skill learning. For this purpose, 320 boys and girls, with ages ranging from 3 to 12 years (M= 7.61; SD= 2.61), took part in nine object movement reception drills in which the following variables were cross-examined: the presence-absence of displacement (static or in motion), the corporal segments utilized (hands or arms), the movement direction (right or left), and the moving object (volleyball or tennis ball). The results indicate that what is being transferred is the common factor among them, the ocular-kinesthetic regulating system, which is constructed according to a generalized motor program and a predictive strategy of continuous control. The way that individuals group by levels of skill that represent the developmental levels of the aforementioned regulating system can also be observed. Lastly, the results are discussed, and strategies to improve the learning process in sports and physical education are provided.     

On Potential-Based and Direct Movements in Information Spaces

Learning can be portrayed as a movement in a state space. Potential-based explanations of such movements hold that learners use a gradient-descent process to minimize a potential function. Direct explanations hold that learning is specific to information for learning. This study contrasts specific hypotheses derived from these general approaches. Participants estimated the length of arrow shafts of Müller-Lyer displays. Experiment 1 shows that learning in this paradigm can indeed be portrayed as a movement in a state space. In Experiment 2 nonveridical feedback was used in such a way that the contrasted hypotheses predicted learning in opposite directions. No learning was observed. In Experiment 3, movements in the state space were observed with practice conditions in which one of the hypotheses specified a movement in the state space whereas the other did not specify any movement. A tentative explanation for these findings is that both hypotheses are partly correct. However, more than to the empirical findings for this particular task, the authors wish to draw attention to the distinction between potential-based and direct processes—a distinction that they consider of general importance for the understanding of learning.     

Preferences for religious help-seeking: racial and gender differences,interfaith intolerance,and defensive theology

We examined the relation between preference for religious help-seeking and defensive theology, interfaith intolerance, spiritual conceptualisations of mental health problems, race/ethnicity, and gender in a predominantly Christian sample of 389 college students. MANOVA revealed significant main effects for race/ethnicity, with African American participants showing higher scores than Caucasians and Latinos/as across all main study variables. Follow-up ANOVA yielded main effects for race across all four variables and main effects for gender on spiritual conceptualisation of mental health problems and defensive theology. All race/ethnicity by gender interactions were nonsignificant. Preference for religious help-seeking was regressed in a hierarchical manner on race/ethnicity and gender, followed by interfaith intolerance, defensive theology, and spiritual conceptualisation of mental health problems. A statistically significant model explaining 46% of the variance emerged incorporating all variables except race. A framework for understanding help-seeking preference is presented, followed by directions for future research.     

Cardiovascular medicine at face value: a qualitative pilot study on clinical axiology

Introduction

Cardiology is characterized by its state-of-the-art biomedical technology and the predominance of Evidence-Based Medicine. This predominance makes it difficult for healthcare professionals to deal with the ethical dilemmas that emerge in this subspecialty. This paper is a first endeavor to empirically investigate the axiological foundations of the healthcare professionals in a cardiology hospital. Our pilot study selected, as the target population, cardiology personnel not only because of their difficult ethical deliberations but also because of the stringent conditions in which they have to make them. Therefore, there is an urgent need to reconsider clinical ethics and Value-Based Medicine. This study proposes a qualitative analysis of the values and the virtues of healthcare professionals in a cardiology hospital in order to establish how the former impact upon the medical and ethical decisions made by the latter.

Results

We point out the need for strengthening the roles of healthcare personnel as educators and guidance counselors in order to meet the ends of medicine, as well as the need for an ethical discernment that is compatible with our results, namely, that the ethical values developed by healthcare professionals stem from their life history as well as their professional education.

Conclusion

We establish the kind of actions, communication skills and empathy that are required to build a stronger patient-healthcare professional relationship, which at the same time improves prognosis, treatment efficiency and therapeutic adhesion.

     

Revisiting Case IV: A reassessment of bias and standard errors of Case IV under range restriction

In 2004, Hunter and Schmidt proposed a correction (called Case IV) that seeks to estimate disattenuated correlations when selection is made on an unmeasured variable. Although Case IV is an important theoretical development in the range restriction literature, it makes an untestable assumption, namely that the partial correlation between the unobserved selection variable and the performance measure is zero. We show in this paper why this assumption may be difficult to meet and why previous simulations have failed to detect the full extent of bias. We use meta‐analytic literature to investigate the plausible range of bias. We also show how Case IV performs in terms of standard errors. Finally, we give practical recommendations about how the contributions of Hunter and Schmidt (2004) can be extended without making such stringent assumptions.     

The Carnales

Once, and only once, I had to fight for my life. The experience catapulted me to an edge of my being that I am glad to have found but don't want to visit too often–an edge others may seek by climbing a glacier, trekking in Nepal, or fasting for a week to induce visions. I am not a thrill-seeker, but a lazy quester content to make do with the ample shocks life has brought me unsought.     

What counts as evidence for working memory training? Problems with correlated gains and dichotomization

The question of whether computerized cognitive training leads to generalized improvements of intellectual abilities has been a popular, yet contentious, topic within both the psychological and neurocognitive literatures. Evidence for the effective transfer of cognitive training to nontrained measures of cognitive abilities is mixed, with some studies showing apparent successful transfer, while others have failed to obtain this effect. At the same time, several authors have made claims about both successful and unsuccessful transfer effects on the basis of a form of responder analysis, an analysis technique that shows that those who gain the most on training show the greatest gains on transfer tasks. Through a series of Monte Carlo experiments and mathematical analyses, we demonstrate that the apparent transfer effects observed through responder analysis are illusory and are independent of the effectiveness of cognitive training. We argue that responder analysis can be used neither to support nor to refute hypotheses related to whether cognitive training is a useful intervention to obtain generalized cognitive benefits. We end by discussing several proposed alternative analysis techniques that incorporate training gain scores and argue that none of these methods are appropriate for testing hypotheses regarding the effectiveness of cognitive training.     

EFFECTS OF AN INDEPENDENT GROUP CONTINGENCY SPECIAL ACTIVITY PROGRAM ON INAPPROPRIATE BEHAVIOR IN A RESIDENTIAL SETTING

Group contingencies targeting inappropriate behavior may be especially useful in residential settings where the staff to client ratio makes individualized behavior plan implementation difficult. The purpose of the current study was to evaluate an independent group contingency on inappropriate behavior in a secure residential facility for offenders with disabilities. The independent group contingency involved differential reinforcement of low rate and differential reinforcement of other behavior via access to a special activity (a catered weekly lunch). The group contingency was alternated with non‐activity weeks for a total of 48 weeks. Results were analyzed across and within residents and showed lower overall rates of inappropriate behavior on activity weeks than non‐activity weeks for the majority of residents.
