Target identification has usually been studied with respect to environmental parameters which affect the performance of the “human operator.” Rather than use this method, which treats individual differences as sources of error, the investigators studied individual differences and related them to Witkin's concept of perceptual style. Witkin and his associates were able to differentiate subjects on their ability to pull a visual item from an embedding context. Two experiments were conducted using the Embedded Figures Test (EFT) as a measure of perceptual style. Significant correlations between perceptual style and the ability to correctly identify targets in aerial photographs were found. Since a great deal of research has been conducted in the area of perceptual style, it is possible to utilize this research in connection with problems associated with target identification. Implications in the areas of experimental design, selection, and training were discussed.

A study was done to assess the ability for visual search and recognition of roadside targets and safety errors during a landmark and traffic sign identification task in drivers with stroke, that is, drivers who have had a stroke. Visual search for roadside targets during automobile driving can compete for a driver's cognitive resources and may impair driving, especially in drivers with cognitive impairment caused by stroke. Thirty-two drivers with stroke and 137 neurologically normal older adults underwent a battery of visual, cognitive, and motor tests and were asked to report sightings of specific landmarks and traffic signs along a segment of an experimental drive. The drivers with stroke identified significantly fewer landmarks and traffic signs and showed a tendency to make more at-fault safety errors during the task than did control subjects. Roadside target identification performance and safety errors were predicted by scores on standardized tests of visual, cognitive, and motor function. Drivers with stroke are impaired in a task of visual search and recognition of roadside targets whose demands on visual perception, attention, executive functions, and memory probably increased the cognitive load and worsened their driving safety.

<p class="0abstract">Context-aware mobile applications can adapt to different mobile, user and application contexts. Mobile cloud computing has been integrated with those applications to benefit from the cloud resources and make up for the limited mobile resources. This paper proposes such an application for the assessment and training of student visual cognitive abilities and skills that constitute an integral part of student intelligence such as the visualization ability of recognizing rotated objects. The need to ubiquitously and continuously deliver exercises relevant to a specific visual cognitive ability or skill according to the student proficiency and context has stimulated proposing the context-aware cloud-based MObile application for assessment and training of visual Cognitive Abilities (MOCA) presented in this paper. Integrating cloud computing with MOCA allows creating an extendible repository on the cloud and saving the relatively limited mobile resources that would be consumed by visual material. MOCA can be used in applications that are based on such cognitive abilities such as teaching visual science concepts and the visual classification and diagnosis of medical images. Two prototype mobile applications have been developed based on MOCA for visualization ability and for visual classification of science concepts. Empirical evaluation has shown the effectiveness of MOCA in training the students and the satisfaction of the students and teachers with its capabilities. MOCA is also a framework for building systems for other types of cognitive abilities.</p>

Abstract Objectives Visual cognitive performance (VCP) is an important factor in high-speed interactions with the environment such as sports or driving, however, the testing, training and determination of factors that influence this ability has been elusive. Iron intake from heme sources has been shown to prevent altered metabolic processes, reductions in protein and neurotransmitter synthesis, and cognitive abilities and neural functions. The purpose of this study is to determine whether chronic dietary iron intake explain the large difference in VCP and training responses between healthy individuals. Methods Men and women age 18–35 completed 15 visual cognitive training sessions (Neurotracker) in 10 visits to the laboratory. On the days of training, all food intake was documented (Nutribase) along with measures of body composition, blood pressure, hydration status, sleep patterns, and recent exercise. Mean nutritional intakes were calculated for the 10 days of food records. Total daily intakes of iron were also calculated for each of the 10 days of food records. Results Iron intake was significantly associated to VCP (P &lt; 0.001) in women (N = 52) but not men (N = 36). VCP improved progressively with dietary iron intake in women from low (iron: 8.2 ± 1.2 mg/day, VCP: 1.38 ± 0.22, N = 24), medium (iron: 13.4 ± 1.3 mg/day, VCP = 1.59 ± 0.38, N = 21) to high (20.9 ± 3.8 mg/day, VCP = 1.86 ± 0.33, N = 7) in which all groups were all significantly different from each other (P &lt; 0.05). Conclusions These results suggest that intakes of iron at or above the RDA may be essential to optimize VCP. Funding Sources National Cattlemen's Beef Association.

Purpose In 2011, the United Nations estimated there were between 180 and 220 million youth with disabilities living around the world, and 80% of them resided in developing countries. Over the last 6 years, this number has increased significantly, and now, over 1 million people live in the Caribbean with some form of disability such as communication disorders resulting in complex communication needs (CCN). Method This publication discusses the benefits of an exploratory, descriptive, nonexperimental study on augmentative and alternative communication (AAC) classroom integration training for 8 special educators in the Bahamas who work with children with CCN. Results The results of this study revealed that 100% of the participants reported the study to be effective in increasing their knowledge and skill in the area of implementing AAC into their classrooms, enhancing their ability to team teach and incorporate AAC opportunities for all students with CCN within their classrooms, and increasing their knowledge and skill overall in the areas of AAC and CCN. Conclusion The findings highlight an important area of potential professional development and training that can be replicated in other English-speaking Caribbean territories focused on AAC classroom integration training program for special educators who teach students with CCN.

Purpose The aim of this study was to examine how hearing aid candidates perceive user-driven and app-controlled hearing aids and the effect these concepts have on traditional hearing health care delivery. Method Eleven adults (3 women, 8 men), recruited among 60 participants who had completed a research study evaluating an app-controlled, self-fitting hearing aid for 12 weeks, participated in a semistructured interview. Participants were over 55 years of age and had varied experience with hearing aids and smartphones. A template analysis was applied to data. Results Five themes emerged from the interviews: (a) prerequisites to the successful implementation of user-driven and app-controlled technologies, (b) benefits and advantages of user-driven and app-controlled technologies, (c) barriers to the acceptance and use of user-driven and app-controlled technologies, (d) beliefs that age is a significant factor in how well people will adopt new technology, and (e) consequences that flow from the adoption of user-driven and app-controlled technologies. Specifically, suggested benefits of the technology included fostering empowerment and providing cheaper and more discrete options, while challenges included lack of technological self-efficacy among older adults. Training and support were emphasized as necessary for successful adaptation and were suggested to be a focus of audiologic services in the future. Conclusion User perceptions of user-driven and app-controlled hearing technologies challenge the audiologic profession to provide adequate support and training for use of the technology and manufacturers to make the technology more accessible to older people.
