Kinship and network: A cognitive model of interaction

This research utilizes aspects of informants' cognition of their kinship relations to generate a hypothetical model of mobilizations of kinsmen for the accomplishment of tasks. Informants produced rankings of the relative strengths of expected norm fulfillment with respect to various kinsmen. These rankings were then scaled. The correlations among the resulting scales were factor analyzed to reveal clusters of kinsmen. These clusters reflect general levels of normative expectation of the kinsmen and, thus, their relative likelihood of recruitment in mobilizations.     

Feasibility and acceptability of a child sexual abuse prevention program for childcare professionals: comparison of a web-based and in-person training

Recent prevention research has established the efficacy of some child sexual abuse prevention programs targeting adults; however, less is known about the feasibility of implementing such programs. The current study examines the feasibility and acceptability of a child sexual abuse prevention program for child care professionals provided in two different formats: in person and Web based. The sample consisted of 188 child care professionals from a large-scale, multisite, randomized controlled trial. Findings indicate that both in-person and online training formats are feasible to implement and acceptable to professionals. When comparing formats, the in-person format was favored in terms of comfort level and likelihood of sharing information with others. These findings have significant implications for dissemination of child sexual abuse prevention programs for child care professionals.     

Infant feeding: the interfaces between interaction design and cognitive ergonomics in user-centered design

This text presents a discussion on the process of developing interactive products focused on infant behavior, which result was an interactive game for encouraging infant feeding. For that, it describes the use of cognitive psychology concepts added to interaction design methodology. Through this project, this article sustains how the cooperative use of these concepts provides adherent solutions to users' needs, whichever they are. Besides that, it verifies the closeness of those methodologies to boundary areas of knowledge, such as design focused on user and ergonomics.     

Effects of motor practice on cognitive disorders in older adults

The demographics of our societies have changed drastically during the past few decades. The general population is aging rapidly as human life spans continue to expand and more adults are set to mature during the next quarter century. This aging process has numerous implications for the way we live and will have particularly important impacts on health and healthcare. In particular, substantial evidence suggests that cognitive–motor function deteriorates considerably as the result of inactive life style, biological aging, and cognitive impairments. The number of individuals with Alzheimer's disease (AD), an aging-related cognitive disorder, is expected to increase significantly during the next 40 years. The development of mild cognitive impairment (MCI) or AD can exaggerate the functional declines observed in cognitive or motor performance. The functional declines affect an array of social, cognitive, mental, physical, and motor activities in our daily lives. However, recent studies suggest that cognitive, physical, motor practice, or skill learning can improve motor speed, smoothness, and accuracy in both MCI and AD patients and their age-matched healthy peers. From theoretical and practical perspectives, this paper addresses several critical aspects of motor deficits and the kinematical characteristics of motor skill development in MCI and AD populations. Empirical data will be presented relative to the sensory–motor functions of MCI and AD, the motor skill acquisition, exercise rehabilitation in older adults with memory loss, as well as the implications for therapies. Finally, this review concludes with thoughts and suggestions for future research in these areas.     

Appropriateness and acceptability: Employee perspectives of internal communication

Internal communication underpins organisational effectiveness since it contributes to positive internal relationships by enabling communication between senior managers and employees. Paradoxically, internal communication can also pose a threat to organisational relationships, as poor communication can be counter-productive. The potential benefits of internal communication rely on appropriate messages reaching employees in formats useful and acceptable to them. Consequently, insight into employee preferences for mediated internal communication is required. The paper investigates employee views on the format of internal publications, contrasting acceptable attributes with elements which attract criticism. The single-case study contributes consideration of fresh data on an under-researched topic. It adopts a stakeholder approach with an employee-centric emphasis on employee preferences, in contrast to much previous research which focuses on manager perceptions of internal communication. Contributions include consideration of practical implications of the findings together with suggestions for avenues of further research.     

Effect of resistance-exercise training on cognitive function in healthy older adults: a review

Several studies have demonstrated that exercise helps reduce or prevent cognitive deterioration among older adults, and recent studies have further examined the effects of resistance-exercise training on cognition. The purpose of this review was to examine the role of resistance-exercise training on cognition in healthy older adults. Specifically, it describes the definition, health benefits, and the design of resistance-exercise training. The authors also review the research related to resistance exercises and cognition and found that this exercise modality may enhance specific cognitive performances. Next, they examine the potential mechanisms underlying resistance exercise and cognitive enhancement. Finally, they consider potential therapeutics and recommendations for further research on resistance-exercise training and cognition in older adults.     

Concurrent cognitive task may improve motor work performance and reduce muscle fatigue

Performance of certain cognitive tasks either during physical load or in rest pauses between boosts might lead to slowing of muscle fatigue and fatigue related decline in performance. Seventeen right-handed healthy volunteers (age 24 ± 1.4, 8 males) participated in this study, aiming to investigate the effect of the level of the cognitive information processing - 1) passive perception of audio stimuli, 2) active stimuli discrimination, 3) active stimuli discrimination following motor response - on motor task performance (handgrip test 30% and 7% of MVC) and muscle fatigue development. Cognitive tasks show the following effects on motor work: i) Perceived fatigue during 30 % MVC (fatiguing) condition developed slower if participant pressed button in response to deviant acoustic stimuli, as compared to passive listening. Counting task, an active task without motor component, took the intermediate position and did not differ significantly from two other cognitive tasks. ii) MVC after 30% MVC (fatiguing) condition tended to decrease stronger when accompanied with passive listening in comparison with both active tasks. iii) Motor task performance during 30% MVC (fatiguing) condition was better for active cognitive task with motor component than for passive task. Active task without motor component took the intermediate position and did not differ significantly from both the other cognitive tasks.

The beneficial effects of different types of exercise interventions on motor and cognitive functions in older age: a systematic review

The decline in cognitive and motor functions with age affects the performance of the aging healthy population in many daily life activities. Physical activity appears to mitigate this decline or even improve motor and cognitive abilities in older adults. The current systematic review will focus mainly on behavioral studies that look into the dual effects of different types of physical training (e.g., balance training, aerobic training, strength training, group sports, etc.) on cognitive and motor tasks in older adults with no known cognitive or motor disabilities or disease. Our search retrieved a total of 1095 likely relevant articles, of which 41 were considered for full-text reading and 19 were included in the review after the full-text reading. Overall, observations from the 19 included studies conclude that improvements on both motor and cognitive functions were found, mainly in interventions that adopt physical-cognitive training or combined exercise training. While this finding advocates the use of multimodal exercise training paradigms or interventions to improve cognitive-motor abilities in older adults, the sizeable inconsistency among training protocols and endpoint measures complicates the generalization of this finding.     

Influence of door handles design in effort perception: accessibility and usability

The application of ergonomics in product design is essential to its accessibility and usability. The development of manual devices should be based on ergonomic principles. Effort perception analysis is an essential approach to understand the physical and subjective aspects of the interface. The objective of the present study was to analyze the effort perception during a simulated task with different door handles by Portuguese subjects of both genders and different ages. This transversal study agreed with ethical aspects. 180 subjects of both genders pertaining to three age groups have participated. Five door handles with different shapes were evaluated. A subjective numeric rating scale of 5 levels was used to evaluate the effort. For statistical analysis it was applied the Friedman non-parametric test. The results have showed no significant differences of effort perception in door handles "A" and "B"; "A" and "D"; and "D" and "C". Door handle "E" presented the lowest values of all. In general, there's an inverse relationship between the results of biomechanical studies and the effort perception of the same task activity. This shows that door handles design influence directly these two variables and can interfere in the accessibility and usability of these kinds of products.     

Perceived inflation: The role of product accessibility and attitudes towards inflation

Little is known about the psychological mechanisms underlying judgments of perceived inflation as empirical evidence is sparse. In two studies, we investigated two factors that are expected to play a significant role in global judgments of perceived inflation: product accessibility and attitudes towards inflation. In Study 1 (N = 253), primed participants retrieved five products whose prices had increased (or decreased) in the past year before expressing a judgment of past inflation (versus non-primed participants with no retrieval task). In Study 2 (N = 101) participants were merely exposed to a series of products, and asked to estimate their frequency of purchase, before judging past inflation. In one condition, the prices of the majority of products had actually increased in the last year, while in another condition they had decreased. In both studies, attitudes towards inflation were also measured. Product priming consistently affected inflation judgments in the direction of an assimilation effect. Also, more negative attitudes towards inflation were associated with higher judgments of perceived inflation. Path analysis confirmed that both product accessibility and attitudes are potential bases for judgments of perceived inflation. These findings suggest that multiple psychological influences may underlie global judgments of perceived inflation.     

Needs and beliefs in construct accessibility: Keys to new understanding

In a general-population survey of 390 Ohioans, respondents rated five concepts as to closeness of linkage with osteopathic medicine. As suggested by the storage-bin concept in construct-accessibility theory, those who had experience with these concepts were most apt to use them in assessing osteopathic medicine. This held even though most respondents reported no contact with osteopathy.Also, those satisfied with their health insurance tended more than others to weigh “niceties” such as wellness heavily in assessing osteopathy. At the other extreme, persons without health insurance gave strong emphasis to cost-containment when evaluating this health-care school.     

Assessment of workplace product accessibility: a human factors perspective

This paper illustrates the advantages of using human factors evaluation techniques as a method of informing rehabilitation service provider decisions about client care and assistive technology selection. Successful integration of accessibility evaluation techniques can strengthen an evidence based service program and offer service providers another tool for providing efficient, effective, and rapid services to individuals in need. With accessibility evaluation data showing the functional abilities required to operate a given product or set of products, it is possible to empirically demonstrate that an individual has the potential to successfully utilize the provided workplace equipment. Conversely, if the accessibility evaluation data reveal that the functional capabilities required to use a product exceed the capabilities of a given user, it would be possible to demonstrate the need for particular interventions or accommodations. With accessibility evaluation data, service providers can make better informed decisions about client care.     

The accessibility and applicability of knowledge: predicting context effects in national surveys

Using data from the National Health Interview Survey on Disability from 1994 and 1995, this research demonstrates that the size of accessibility effects (increased likelihood of using information activated by initial questions in responding to subsequent questions) can be modeled as a function of the applicability of the initial to the subsequent questions. When respondents reported a disability and were asked about the main condition causing the disability, they were more likely to report conditions they had been asked about earlier in the interview than alternative conditions. This accessibility effect was inversely related to the effect on reports of "other" or unclassifiable conditions. The more reports of primed conditions, the fewer reports of unclassifiable conditions. A log-linear model of the accessibility bias fit the data for all disabilities. For reports of specific conditions, a measure of the applicability of context accounted for 74.4 percent of the variance of the accessibility bias; for unclassifiable or "other" conditions, it accounted for 61 percent. When limited to "well-defined" disabilities, applicability accounted for 91.9 percent of the variance (a multiple correlation of.96). Finally, models of the context effects derived from the 1994 data were tested against the actual effects for the 1995 data. The correlation between predicted and actual effects was.80 across disabilities. The theoretical and the practical implications of the findings are discussed.     

Rural accessibility problems and human resource development: Case study from Nigeria

This paper focuses on rural transport as a crucial factor in rural development. It examines the problems posed by poor transportation and the extent to which these constitute constraints to the mobilization of human resources for rural development. Using Kwara State. Nigeria, as a case study, the study shows the poor nature of rural transport network and its effect on the evacuation of agricultural products from the farm centres to markets. This accessibility problem was found to have negative effects on the farmers who are not in the least motivated to increase the acreage cultivated.
