Immediate and delayed recall of a small-scale spatial array

The study examined people's spatial memory of a small-scale array of objects. Earlier work has primarily relied on short-retention intervals, and to date it is not known whether performance is affected by longer intervals between learning and recall. In the present investigation, university students studied seven target objects. Recall was tested immediately after learning and after an interval of seven days. Performance was found to be similar in the immediate and delayed conditions, and the results suggested that recall was facilitated by egocentric and intrinsic cues. The findings are discussed with reference to recent investigations that have shown task parameters can influence spatial recall.     

The Effects of Imagery Training on Swimming Performance: An Applied Investigation

A multiple-baseline design was used to examine the influence of an imagery intervention on the performance of swimmers’ times on a thousand-yard practice set. Performance times for four swimmers were collected over a 15-week period during preseason training. The intervention took place over a 3-week period and was introduced after the fourth week of the study. The results revealed that three out of four participants significantly improved their times on the one thousand-yard practice set after being introduced to the imagery intervention. The results are discussed in terms of the implications of using imagery to improve athlete's performance on continuous tasks.     

Boosting Attachment Security to Promote Mental Health,Prosocial Values,and Inter-Group Tolerance

In this article, we conceptualize the sense of attachment security as an inner resource and present theory and research on the broaden and build cycle of attachment security generated by the actual or symbolic encounter with external or internalized loving and caring relationship partners. We also propose that the body of research stimulated by attachment theory offers productive hints about interventions that might increase positive experiences and prosocial behavior by bolstering a person's sense of security. On this basis, we review recent experimental studies showing how interventions designed to increase attachment security have beneficial effects on mental health, prosocial behavior, and intergroup relations, and discuss unaddressed issues concerning the mechanism underlying the beneficial effects of these interventions, the temporal course of these effects, and their interaction with countervailing forces.     

Responsible Conduct of Research Training and Trust Between Research Postgraduate Students and Supervisors

The federal regulations of human research were written to permit the use of discretion so that research can fit the circumstances under which it is conducted. For example, the researcher and institutional review board (IRB) could waive or alter some informed consent elements if they deem this the morally and scientifically best way to conduct the research. To do so, however, researchers and IRBs would first have to use mature moral and scientific judgment. They might also have to rely on empirical research to discover the most effective way to act on their moral sense (e.g., to discover how best to approach potential research participants and explain the nature and purpose of the research participation for which they are being recruited, to ensure comprehension and competent decision making). On discovering the most ethical way to proceed, they would then need to look to the federal regulations of human research to discover how to document their decision and justify it within that somewhat flexible regulatory structure. Unfortunately, many IRBs and researchers fail to take these sensible steps to solve ethical problems and proceed immediately to a default requirement of the regulations that places science at odds with the regulations and, ostensibly, with ethics. The following articles in this special issue are about the process of learning to engage in ethical problem solving and using the flexibility permitted by the federal regulations. These articles extricate researchers from the mindset that has gotten them into trouble, and, ideally, provoke them to use mature common sense and moral judgment.     

Egg arrangement in avian clutches covaries with the rejection of foreign eggs

In birds, the colour, maculation, shape, and size of their eggs play critical roles in discrimination of foreign eggs in the clutch. So far, however, no study has examined the role of egg arrangement within a clutch on host rejection responses. We predicted that individual females which maintain consistent egg arrangements within their clutch would be better able to detect and reject foreign eggs than females without a consistent egg arrangement (i.e. whose eggs change positions more often across incubation). We tested this “egg arrangement hypothesis” in blackbirds (Turdus merula) and song thrush (T. philomelos). Both species are suitable candidates for research on egg rejection, because they show high inter-individual variation and individual repeatability in egg rejection responses. As predicted, using our custom-defined metrics of egg arrangement, rejecter females’ clutches showed significantly more consistent patterns in egg arrangement than acceptor females’ clutches. Only parameters related to blunt pole showed consistent differences between rejecters and acceptors. This finding makes biological sense because it is already known that song thrush use blunt pole cues to reject foreign eggs. We propose that a disturbance of the original egg arrangement pattern by the laying parasite may alert host females that maintain a consistent egg arrangement to the risk of having been parasitized. Once alerted, these hosts may shift their discrimination thresholds to be more restrictive so as to reject a foreign egg with higher probability. Future studies will benefit from experimentally testing whether these two and other parasitized rejecter host species may rely on the use of consistent egg arrangements as a component of their anti-parasitic defence mechanisms.     

The simple man: The consumption behavior of the principled life

In this study, we analyze the Simple Man, a label for those men who have above-average means in education, household income, or net worth but who consume inconspicuously and modestly below their means. We interviewed 27 men in the Northwest, Midwest, Southeast and Northeast regions of the United States and found that these men have highly individualistic identities and backgrounds yet appear to stray from products that separate them from others. These men also seem to have reached a level of contentment, not needing products or material possessions to achieve fulfillment, status, or a particular masculine identity. These men have practical and durable tastes that reflect low cultural capital (LCC) consumption but have the means and education in many instances to engage in high cultural capital (HCC) consumption. The men in this study adamantly proclaim that they do not define themselves by what they own nor do they appear to define themselves primarily by what they do, at least in terms of occupation. In short, these men appear complex in many ways yet live simple lives, or what might be termed complex simplicity. Copyright © 2013 John Wiley & Sons, Ltd.     

Post-Traumatic Stress Disorder,Sensory Integration,and Aquatic Therapy: A Scoping Review

The prevalence of post-traumatic stress disorder (PTSD) continues to increase. Symptomology of PTSD include sensory deficits much like those displayed in children with sensory integration (SI) disorder. The aim of this scoping review is to review symptoms of PTSD and SI, and make a case of how aquatic therapy may be an effective modality in treating clients with PTSD. Eighteen articles were selected for review. From this review, it is suggested that aquatic therapy can be an effective modality in reducing symptoms of PTSD; however, future research is essential in determining its effectiveness.
