Toward a New Attrition Screening Paradigm: Latest Army Advances

Managing and reducing attrition during the first term of enlistment is a continuing priority for the services. Over the past decade, attrition rates in the Army have averaged between 25% and 30% during first-term periods of enlistment. Historically, the services have relied on education credentials, with special emphasis on possessing a high school diploma, as a primary indicator of completion rates after enlistment and as a proxy for the ability to adapt to a military lifestyle. A primary purpose of this paper is to describe Army research to develop new indicators of adaptability to augment the current system based on education credentials. This work has focused primarily on noncognitive, personality measures and how such measures can be combined with other existing measures for attrition screening during enlistment processing. These advances represent a new paradigm that relies less heavily on education credentials and can provide a more comprehensive and inclusive approach. This new approach incorporates advances in testing methodology to make it more viable for use in large-scale, high-stakes testing applications.     

Making Common Sense of Vaccines: An Example of Discussing the Recombinant Attenuated Salmonella Vaccine with the Public

Researchers have iterated that the future of synthetic biology and biotechnology lies in novel consumer applications of crossing biology with engineering. However, if the new biology’s future is to be sustainable, early and serious efforts must be made towards social sustainability. Therefore, the crux of new applications of synthetic biology and biotechnology is public understanding and acceptance. The RASVaccine is a novel recombinant design not found in nature that re-engineers a common bacteria (Salmonella) to produce a strong immune response in humans. Synthesis of the RASVaccine has the potential to improve public health as an inexpensive, non-injectable product. But how can scientists move forward to create a dialogue of creating a ‘common sense’ of this new technology in order to promote social sustainability? This paper delves into public issues raised around these novel technologies and uses the RASVaccine as an example of meeting the public with a common sense of its possibilities and limitations.     

The influence of cognitive load on spatial search performance

During search, executive function enables individuals to direct attention to potential targets, remember locations visited, and inhibit distracting information. In the present study, we investigated these executive processes in large-scale search. In our tasks, participants searched a room containing an array of illuminated locations embedded in the floor. The participants’ task was to press the switches at the illuminated locations on the floor so as to locate a target that changed color when pressed. The perceptual salience of the search locations was manipulated by having some locations flashing and some static. Participants were more likely to search at flashing locations, even when they were explicitly informed that the target was equally likely to be at any location. In large-scale search, attention was captured by the perceptual salience of the flashing lights, leading to a bias to explore these targets. Despite this failure of inhibition, participants were able to restrict returns to previously visited locations, a measure of spatial memory performance. Participants were more able to inhibit exploration to flashing locations when they were not required to remember which locations had previously been visited. A concurrent digit-span memory task further disrupted inhibition during search, as did a concurrent auditory attention task. These experiments extend a load theory of attention to large-scale search, which relies on egocentric representations of space. High cognitive load on working memory leads to increased distractor interference, providing evidence for distinct roles for the executive subprocesses of memory and inhibition during large-scale search.     

Predictors of Genetic Testing Decisions: A Systematic Review and Critique of the Literature

Genetic testing is increasingly available in medical settings and direct-to-consumer. However, the large and growing literature on genetic testing decisions is rife with conflicting findings, inconsistent methodology, and uneven attention across test types and across predictors of genetic testing decisions. Existing reviews of the literature draw broad conclusions but sacrifice nuanced analysis that with a closer look reveals far more inconsistency than homogeny across studies. The goals of this paper are to provide a systematic review of the empirical work on predictors of genetic testing decisions, highlight areas of consistency and inconsistency, and suggest productive directions for future research. We included all studies that provided quantitative analysis of subjective (e.g., perceived risk, perceived benefits of testing) and/or objective (e.g., family history, sociodemographic variables) predictors of genetic testing interest, intentions, or uptake, which produced a sample of 115 studies. From this review, we conclude that self-reported and test-related (as opposed to disorder-related or objective) predictors are relatively consistent across studies but that theoretically-driven efforts to examine testing interest across test types are sorely needed.     

The perception of a familiar face is no more than the sum of its parts

Why do faces become easier to recognize with repeated exposure? Previous research has suggested that familiarity may induce a qualitative shift in visual processing from an independent analysis of individual facial features to analysis that includes information about the relationships among features (Farah, Wilson, Drain, & Tanaka Psychological Review, 105, 482–498, 1998; Maurer, Grand, & Mondloch Trends in Cognitive Science, 6, 255–260, 2002). We tested this idea by using a “summation-at-threshold” technique (Gold, Mundy, & Tjan Psychological Science, 23, 427–434, 2012; Nandy & Tjan Journal of Vision, 8, 3.1–20, 2008), in which an observer’s ability to recognize each individual facial feature shown independently is used to predict their ability to recognize all of the features shown in combination. We find that, although people are better overall at recognizing familiar as opposed to unfamiliar faces, their ability to integrate information across features is similar for unfamiliar and highly familiar faces and is well predicted by their ability to recognize each of the facial features shown in isolation. These results are consistent with the idea that familiarity has a quantitative effect on the efficiency with which information is extracted from individual features, rather than a qualitative effect on the process by which features are combined.     

Job design,opportunities for skill utilization,and intrinsic job satisfaction

Arguably, job designs that provide for high levels of employee control also provide increased opportunities for the development and exercise of skill. Perceived skill utilization has consistently been found to be amongst the strongest predictors of job-related affective well-being, yet is frequently neglected in studies of work redesign. In this article, a theoretical framework linking the key job characteristics of perceived control and perceived cognitive demand to perceived skill utilization and intrinsic job satisfaction is presented. Results from one cross-sectional study and one longitudinal study are reported that support the mediational influence of perceived skill utilization on the perceived job control?–?job satisfaction relationship only. The relationship between perceived job demand and perceived skill utilization was mixed but no mediating effect was evident. It is argued that the level of both perceived demand and perceived control dictates the nature of the joint influence of both job characteristics on perceived skill utilization and work attitudes such as job satisfaction.     

Religion and obsessive-compulsive disorder (OCD) among young Muslim women in Saudi Arabia

Fifteen young women suffering from OCD in Saudi Arabia were interviewed about their experience of the illness and the roles played by religion. Religion was not perceived as a cause of the illness, but the illness can show itself in religious symptoms – notably with respect to prayer, and in a phase in which the young women were very strict and literal-minded with themselves and their families, with respect to religious observance. Religious symptoms were reported as more upsetting than other symptoms – being seen as damaging to the sufferer's piety. Other facets of the importance of religion in the experience of OCD were shown in help-seeking, in choosing to go first to religious healers for treatment, and only when these were unsuccessful were mental health professionals consulted. At this point, it was very important that the professional should be seen as trustworthy, and the criterion of trustworthiness was religiosity, specifically the use of pious, Qura’anic quotations, and a covered face (for a woman)/long beard (for a man). The accounts of the roles of religion in the experiences of the young women interviewed suggest that religion is an arena – but not the sole arena – for the expression of OCD symptoms. Religion plays an important role in determining the acceptability of treatments and treatment providers.     

Effects of hearing and vision impairments on the Montreal Cognitive Assessment

Many standardized measures of cognition include items that must be seen or heard. Nevertheless, it is not uncommon to overlook the possible effects of sensory impairment(s) on test scores. In the current study, we investigated whether sensory impairments could affect performance on a widely used screening tool, the Montreal Cognitive Assessment (MoCA). Three hundred and one older adults (mean age = 71 years) completed the MoCA and also hearing and vision tests. Half of the participants had normal hearing and vision, 38% impaired hearing, 5% impaired vision, and 7% had dual-sensory impairment. More participants with normal sensory acuity passed the MoCA compared to those with sensory loss, even after modifying scores to adjust for sensory factors. The results suggest that cognitive abilities may be underestimated if sensory problems are not considered and that people with sensory loss are at greater risk of cognitive decline.     

Global Predictions of Memory in Alzheimer’s Disease: Evidence for Preserved Metamemory Monitoring

Previous researchers have argued that there is a metamemory monitoring deficit in Alzheimer’s disease (AD) because patients tend to overestimate their recall performance on a word list. We propose that these previous results are a misleading by-product of the methodologies used, rather than evidence of an underlying metamemory deficit. In two experiments, AD patients and older adult controls made predictions of performance both before and after encoding a to-be-remembered list. Metamemory function was measured by observing the shift in predictions made with, and without, an opportunity to monitor the list. Experiment 1 found that although there were differences between the groups’ accuracy for their prestudy predictions of recall, both groups were equally accurate after encoding. Experiment 2 explored this using four lists that varied in item difficulty and semantic relatedness. This experiment replicated the findings of Experiment 1, and it was also found that the AD group became more accurate at predicting their performance with more exposure to study-test trials. These studies suggest that metamemory monitoring is intact in AD, because AD patients utilize information gained during processing the to-be-remembered items to revise their predictions of subsequent performance.
