The hippocampus is closely tied to spatial navigation, a central component in cognitive functioning, and critically involved in age-associated cognitive decline and dementia. This study evaluated a novel, cognitive computerized spatial navigation training (CSNT) program targeting the hippocampus, with expectation of mitigating possible cognitive decline with bed rest (BR). During a 14-day BR study with 16 healthy, older men (mean age = 60 ± 3, range = 55–65 years), half received CSNT for 12 days in 50-min sessions and half were controls (watching documentaries). This design uniquely controlled diet, sleep, and other personal and environmental activities. Although there were no cognitive declines in controls post-BR, CSNT participants demonstrated significant increases in executive/attention ability and processing speed, and continued spatial navigation testing showed improvement to 400 days post-BR. This intervention may prove useful to mitigate cognitive declines known to occur in long periods of immobilization and could have broader implications in protecting against age-related cognitive decline.  相似文献

Children as pedestrians are one of the most vulnerable groups of road users. Therefore factors associated with risky pedestrian behaviour should be carefully studied. The aim of this article is to clarify how the traffic behaviour of 6th grade students as pedestrians is associated with the behaviour of their traffic companions and prevention activities at school, also taking gender into consideration. The research was conducted based on a randomly-selected sample of 1033 6th-grade students with the mean age of 12.77 ± 0.38 (SD) years. The results showed that compared to girls boys take significantly more risks as pedestrians: they rarely use reflectors during periods of darkness and often cross the road against the red light. The most important role models for adolescents in traffic behaviour are their parents. The role model behaviour with the strongest effect on adolescent high-risk behaviour in traffic is the role model not using crosswalks to cross the street. The results also showed that higher-risk traffic behaviour by adolescent pedestrians is predicted by higher-risk behaviour on the part of their companions (parents, teachers), walking alone on the street, as well as by an adolescent’s lower involvement in the less active prevention activities in the classroom. To improve adolescent pedestrians’ traffic behaviour social environment and school-based factors should be considered more thoroughly in prevention work at school.  相似文献

Many studies have consistently found evidence of aging-related navigation difficulties that lead to disorientation behaviors and/or reduced travel. Despite technological advances, older pedestrians mainly use paper maps to find their way in unknown environments while they have a lot of difficulties in using and interacting with them efficiently. In this context, the present study was aimed at assessing the effectiveness and acceptability and study older pedestrian’s behavior when wearing a vibrotactile instructions to help them finding their way in an unknown city as compared with visual instructions provided by a paper map. Fifty-eight participants (20 young adults ages 21–45, 20 younger-old adults ages 61–70, and 18 older-old adults ages 71–80) took part in a simulated navigation task where participants had to go from point A to point B in a virtual city. The task was performed either with a vibrotactile wristband delivering directional messages or with a standard paper map showing the visual instructions to follow. The data showed that vibrotactile guidance instructions improved the correct numbers of turns taken (left/right) at simple intersections. They also reduced travel time as compared with visual guidance instructions provided by a paper map. These benefits were greater among the older-old participants, who had trouble using the paper map and thus benefited greatly from the assistance provided by the vibrotactile guidance instructions. These findings suggest that such an assistance device using simple haptic guidance messages is able to improve older pedestrians’ mobility.  相似文献

Abstract

This article focuses on the study of where mobile devices and social media tools are taken into consideration in the Finnish confirmation training entity as a new opportunity to work together. The research is based on the ethnographical method. The data was collected by observation in two confirmation training camp periods and interviewing confirmation training participants. The aim was to find out ways mobile devices were exploited in confirmation training pedagogy, how adolescents reacted to such mobile device use and how adolescents described their personal mobile device use. The research material is analysed by inductive content analysis. The findings are discussed in the theoretical context of the communities of practice (CoPs), originally formed by Lave and Wenger . According to the results, mobile device use, in the confirmation training programme did not seem to be that special for adolescents. At the same time, the youth considered it important to have the possibility to use mobile devices according to their own preferences. Using mobile devices in confirmation training challenged the traditional CoP setting, as adolescents used mobile technology more in their own way, being familiar with it in their earlier virtual communities of practice (VCoPs), instead of the plans of the workers of confirmation training.  相似文献

The aim of this study was to investigate the effects of an action observation training on balance and sit to walk in chronic stroke. Twenty-four chronic stroke patients participated in this study. Participants were randomly allocated to either the landscape imagery observation physical training group (LIOPT) or the action observation physical training group (AOPT). LIOPT observed a landscape picture for 2 min 30 s while the AOPT group observed related video recording. Both groups underwent a physical training session after the observation session for 12 min 30 s and the sessions were repeated twice a day, 3 times a week for 6 weeks. Outcome measures included Time Up and Go Test (TUG), Dynamic Gait Index (DGI), Weight Distribution Index (WDI), and limit of stability (LOS). Between-group and within-group comparisons were analyzed using the Mann-Whitney U test and Wilcoxon signed rank test, respectively. The AOPT and LIOPT groups have shown statistically significant differences in TUG, DGI, WDI, and LOS over time. However, no significant difference was observed in terms of TUG, DGI and WDI, but only in LOS between groups. These findings suggest that action observation training and physical training are effective to improve sit to walk and balance ability of chronic stroke patients.  相似文献

This study explored experiences of power among 11 African American female pastoral counselors‐in‐training. Limited research exists within the field of pastoral counseling regarding the dynamics of power within the development of minority counselors‐in‐training. Experiences of power such as microaggressions and empowerment were evidenced in the art created by participants during their qualitative interviews. Use of a heuristic arts‐based research design resulted in 6 final essences (major themes): symbolic analysis of the journey of identity development, empowerment, powerlessness, ownership of power, integration, and pervasive spirituality. Practical implications for counselor educators and pastoral counseling programs are provided.  相似文献

In a class inclusion task, a child must respond to stimuli as being involved in two different though hierarchically related categories. This study used a Relational Frame Theory (RFT) paradigm to assess and train this ability in three typically developing preschoolers and three individuals with autism spectrum disorder, all of whom had failed class inclusion tests. For all subjects, relational training successfully established the target repertoire and subsequent testing demonstrated both maintenance and generalization. Limitations and future research directions are discussed.  相似文献

We summarize the results of four recent translational studies from our lab that used the predictions of behavioral momentum theory to inform the development of more durable treatments for destructive behavior. Treatments informed by behavioral momentum theory generally showed better suppression of target responding during an extinction challenge than did a comparison treatment. We reanalyze data from each of the four studies to show that this general finding is apparent both at the aggregate (i.e., proportion of baseline response rates averaged across participants) and within participant (i.e., percentage reduction in proportion of baseline response rates, difference in raw response rates during the extinction challenge). Interestingly, participants who experienced multiple cycles of the extinction challenge generally showed less differentiation in target responding between the treatment informed by behavioral momentum theory and the comparison treatment. Overall results suggest that applications of behavioral momentum theory can substantially improve the durability of common treatments for destructive behavior.  相似文献

In this paper, the application of computer technology in higher education and management mode based on cognitive anthropology was studied and a teaching recommendation method was constructed. Firstly, on the basis of the existing teaching recommendation research results, teaching recommendation was carried out by adopting the methods of linear weighting and cascade combination and combining with human social factors, geographical factors and time factors, and the validity of the results was improved. Then, the expansion was carried out in the Apache cluster environment, and the efficiency and scalability of teaching recommendation were improved, so that an innovative mode of higher education research and management was created. Experiments show that the implementation efficiency of comprehensive teaching recommendation method achieved in an Apache cluster environment is high. As the amount of data increases, the efficiency advantages become more pronounced.  相似文献

The author used structural equation modeling to estimate the relationship between the working alliance and state mindfulness while controlling for dispositional mindfulness and empathy in 200 counselors‐in‐training (CITs). Results indicated a moderate to large relationship between working alliance and mindful state. The author discusses the distinction between state and dispositional mindfulness, suggests directions for future research, and offers strategies for enhancing state mindfulness among CITs.  相似文献
