Visual versus kinesthetic mental imagery: Efficacy for the retention and transfer of a closed motor skill in young children

The main purposes of this study were (a) to compare the effects of mental imagery combined with physical practise and specific physical practise on the retention and transfer of a closed motor skill in young children; (b) to determine the mental imagery (visual vs. kinesthetic), which is the most efficient for retention and transfer of a closed motor skill; and (c) to verify the relationship between movement image vividness and motor performance. As for the secondary purpose, it was to compare the effects of gender on motor learning. Participants (n = 96) were selected from 3 primary schools. These participants were divided into 6 groups and submitted to different experimental conditions. The experimental task required the participants to throw, with the nondominant hand (left hand), a ball toward a target composed of 3 concentric circles. The results demonstrated that performance obtained by the mental imagery (visual or kinesthetic) combined with physical practise group was, during the retention phase, equivalent to that produced by the specific physical practise group but significantly superior during the transfer of closed motor skill. These results showed the potential benefits of mental imagery as a retention strategy intended for motor skills and performance enhancement. Such results could be explained by the similarity of 3 principal functional evidences shared by mental and physical practise: behavioural, central, and peripheral (as suggested by Holmes & Collins, 2001).

Food for thought: the effect of counterfactual thinking on the use of nutrition information

In three experiments, we examine the efficacy of counterfactual thinking (CFT) as a strategy to enhance consumers' motivation to process and use nutrition information on food packages. In the first study, we test whether CFT leads to greater motivation to process nutrition label information in the process of forming product attitudes. We also test whether motivation mediates the relationship between CFT and the influence of the nutrition label in product evaluation. In a second study, we test the effect of upward versus downward CFT on motivation. We also examine whether nutrition information on food packages moderates the relationship between CFT and product attitudes. In a third study, we examined the duration of the motivational effect of CFT. Results from the three studies support the role of CFT as a mechanism that enhances consumers' motivation to elaborate on and use nutrition information to form product attitudes.

Food and Sustainability Challenges Under Climate Changes

Plants are permanently impacted by their environments, and their abilities to tolerate multiple fluctuating environmental conditions vary as a function of several genetic and natural factors. Over the past decades, scientific innovations and applications of the knowledge derived from biotechnological investigations to agriculture caused a substantial increase of the yields of many crops. However, due to exacerbating effects of climate change and a growing human population, a crisis of malnutrition may arise in the upcoming decades in some places in the world. So, effective, ethical and managerial regulations and fair policies should be set up and applied at the local and global levels so that Earth may fairly provide the food and living accommodation needed by its inhabitants. To save some energy consumption, electric devices (for e.g., smartphones, laptops, street lights, traffic lights, etc.) should be manufactured to work with solar energy, whenever available, particularly in sunny countries where sun is available most of the time. Such characteristic will save energy and make solar energy-based smartphones and laptops less cumbersome in terms of chargers and plugging issues.     

Fake Journals: Not Always Valid Ways to Distinguish Them

In their recent paper, Esfe et al. (Sci Eng Ethics, doi: 10.1007/s11948-014-9595-z 2014) present some criteria for fake journals and propose some ‘features’ to recognize them. While I share most of the authors’ concerns about this issue in general, some of the reported criteria are not fit to differentiate fake journals from genuine ones. Here are some examples derived from their list, which illustrate that such criteria are not necessarily specific to fake journals only, but they could also apply to well-established journals and, therefore, should not be considered as is.     

The Effectiveness of Attachment Injury Resolution Model (AIRM) on Increasing Trust among the Injured Women with Marital Infidelity: A Case Study Approach

Abstract

Objective: The present study aimed at determining the effectiveness of emotionally-focused couple therapy, based on attachment injury resolution model (AIRM) on increasing trust among the injured women with marital infidelity. Method: The present study was a single case experiment of the multiple baseline design type. The population included all injured women with marital infidelity, referring to Bushehr family therapy clinics, among whom three women were selected and participated in the intervention through purposive sampling method, based on the desired recall, By considering the inclusion and exclusion criteria and answering the trust scale. Data analysis was conducted by visual analysis, clinically meaningful (reliable change index and normative comparison) and percentage improvement formula. Results: The percentage obtained from the overall increase of trust among the injured women during the therapy was 38.76 and follow-up was 48.58. In addition, the reliable change index during the therapy and a follow-up was 2.77 and 3.49 in the first couple, 3.10 and 3.62 in the second couple, 2.66 and 3.67 in the third couple indicating that these values were significant and higher than z?=?1.96 during the therapy and follow-up (p?=?0.05). Conclusion: Based on the research results, the emotionally-focused couple therapy based on attachment injury resolution model can be used as an effective intervention in reducing the injuries by marital infidelity.     

Impossible Antecedents and Their Consequences: Some Thirteenth-Century Arabic Discussions

The principle that a necessarily false proposition implies any proposition, and that a necessarily true proposition is implied by any proposition, was apparently first propounded in twelfth century Latin logic, and came to be widely, though not universally, accepted in the fourteenth century. These principles seem never to have been accepted, or even seriously entertained, by Arabic logicians. In the present study, I explore some thirteenth century Arabic discussions of conditionals with impossible antecedents. The Persian-born scholar Afdal al-Dīn al-Khūnajī (d.1248) suggested the novel idea that two contradictory propositions may follow from the same impossible antecedent, and closely related to this point, he suggested that if an antecedent implies a consequent, then it will do so no matter how it is strengthened. These ideas led him, and those who followed him, to reject what has come to be known as ‘Aristotle's thesis’ that no proposition is implied by its own negation. Even these suggestions were widely resisted. Particularly influential were the counter-arguments of Naīr al-Dīn al-Tūī (d.1274).     

Does the Cover Letter Really Matter?

Many journals require a covering letter alongside the submission process. Some of them, particularly elitist journals, pay a particular attention to the cover letter to such extent an editor may decide not to send a paper out for external peer-review because of a ‘bad’ or absence of a covering letter. As stated in the instructions of many journals, the goal of the covering letter is to emphasize the novelty and to communicate the potential implications of the reported findings. Authors are also invited to tell the handling editor how the topic is related to the journal’s scope and to demonstrate how the results fit in broader context of the literature. Here, I briefly discuss if the cover letter is really necessary.
