Cognitive processing therapy (CPT) is a first-line, evidence-based treatment for posttraumatic stress disorder (PTSD). Little is known, however, about the use of CPT for older adults. As the United States population continues to grow and age, an understanding of the utility of CPT for older adults is vital. We present a case study describing the assessment and cognitive treatment of a 74-year-old woman veteran with PTSD secondary to military sexual trauma. CPT was associated with decreased PTSD symptoms as measured before and after treatment. Factors contributing to the veteran’s response, as well as contextual and environmental factors, are discussed. The case demonstrates that CPT may be effective for older adults without major modification.  相似文献

The rapid development of urban roads has resulted in an increase in the amount of information that needs to be displayed on traffic signs. The overloading of information on traffic signs may increase drivers’ visual cognition burden and cause driving errors. It could be an important factor affecting driving safety and result in accidents. To enable drivers to cognize traffic signs, the information density that they could endure under reasonable workload levels should be determined. In this study, we designed and implemented trials to analyze drivers’ visual working memory load (VWML) caused by different information densities (including stimulus intensity (SI) and interval time of stimulus (IS)) of traffic signs. Twenty-four paid participants (12 females) with a mean age of 23.38 years (SD = 1.38) participated in laboratory simulation trials based on the memory retrieval approach. Subjective ratings (rating scale mental effort (RSME)), and performance measurement based on reaction time and accuracy of information-matching task were measured to reflect drivers’ VWML at different information densities. The results show that information density is an important factor affecting drivers’ VWML. The following are the significant observations of the study: (1) The subjective ratings on mental effort increased with increase in the SI. Meanwhile, it first decreased and then increased with increase in the IS. (2) The response accuracy results show that a high accuracy (≥0.7) was achieved by drivers in an IS of 15 s when the SI was at most 14.16 bit/m2. Correspondingly, the drivers underwent less mental workload as a result of their better short-term memory characteristic. (3) The mean reaction time was over 1800 ms when the SI was over 14.16 bit/m2. This indicated a reduction in the information-processing capability of the drivers. The results indicate that cognition of information of unreasonable density on traffic signs would increase drivers’ VWML. This would, in turn, result in an increase in their reaction time and decrease in accuracy. The threshold of information density was also determined through the experiment. It would satisfy the information demand of drivers and prevent information redundancy. The results contribute to an understanding of drivers’ VWML while cognizing traffic signs with different information densities and provide safety, effectiveness, and information continuity considerations for the design and setting of traffic signs.  相似文献

When talking about automation, “autonomous vehicles”, often abbreviated as AVs, come to mind. In transitioning from the “driver” mode to the different automation levels, there is an inevitable need for modeling driving behavior. This often happens through data collection from experiments and studies, but also information extraction, a key step in behavioral modeling. Particularly, naturalistic driving studies and field operational trials are used to collect meaningful data on drivers’ interactions in real–world conditions. On the other hand, information extraction methods allow to predict or mimic driving behavior, by using a set of statistical learning methods. In simple words, the way to understand drivers’ needs and wants in the era of automation can be represented in a data–information cycle, starting from data collection, and ending with information extraction. To develop this cycle, this research reviews studies with keywords “data collection”, “information extraction”, “AVs”, while keeping the focus on driving behavior. The resulting review led to a screening of about 161 papers, out of which about 30 were selected for a detailed analysis. The analysis included an investigation of the methods and equipment used for data collection, the features collected, the size and frequency of the data along with the main problems associated with the different sensory equipment; the studies also looked at the models used to extract information, including various statistical techniques used in AV studies. This paved the way to the development of a framework for data analytics and fusion, allowing the use of highly heterogeneous data to reach the defined objectives; for this paper, the example of impacts of AVs on a network level and AV acceptance is given. The authors suggest that such a framework could be extended and transferred across the various transportation sectors.  相似文献

In eight studies, we tested the prediction that making choices for others involves less loss aversion than making choices for the self. We found that loss aversion is significantly lessened among people choosing for others in scenarios describing riskless choice (Study 1), gambling (Studies 2 and 3), and social aspects of life, such as likeably and status (Studies 4a–e). Moreover, we found this pattern in relatively realistic conditions where people are rewarded for making desirable (i.e., profitable) choices for others (Study 2), when the other for whom a choice is made is physically present (Study 3), and when real money is at stake (Studies 2 and 3). Finally, we found loss aversion is moderated when factors associated with self–other differences in decision making are taken into account, such as decision makers’ construal level (Study 4a), regulatory focus (Study 4b), degree of information seeking (Study 4c), omission bias (Study 4d), and power (Study 4e).  相似文献

Diversity can enhance as well as disrupt team performance. Diversity beliefs and climates may play an important moderating role in these effects, but it is unclear what form these should take to promote the positive effects of diversity. Addressing this question in an integration of research in team cognition and diversity, we advance the concept of diversity mindsets, defined as team members’ mental representations of team diversity. These mindsets capture diversity-related goals and associated procedural implications for goal achievement. We develop theory about the accuracy, sharedness, and awareness of sharedness of mindsets as moderators of the diversity-performance relationship. We also identify the determinants of these aspects of diversity mindsets. Finally, we discuss the implications of our model for the management of diversity.  相似文献

DSM-IV-TR defines ADHD-Predominantly Inattentive as allowing up to five symptoms of hyperactivity/impulsivity, while theories of the inattentive type usually assume a group that is hypoactive and characterized by processing speed and cognitive interference deficits. In a community-recruited sample of 572 children and adolescents, a pure inattentive subtype of ADHD (ADD) was defined as those who met DSM-IV-TR criteria for ADHD-PI but had two or fewer hyperactive/impulsive symptoms. Processing and output speeds of those with ADD were compared to those identified with DSM-IV-TR ADHD combined type and non-ADHD controls. These results were then contrasted with those found when DSM-IV-TR defined ADHD-PI was compared with ADHD-C and controls. Processing and output speed were assessed with the Trailmaking A and B and the Stroop Naming Tests. Cognitive interference control was assessed with the interference score from the Stroop Task. Slower cognitive interference speed was found in the ADD vs. ADHD-C and controls comparisons, but not the ADHD-PI versus ADHD-C and controls comparisons. On output speed measures, ADD exhibited the slowest performance, significantly different from controls and the effect size for the set-shifting speed contrast (Trailmaking B) was double that of the ADHD-PI vs. control comparison. ADHD-Inattentive type as defined by the DSM-IV-TR is a heterogeneous condition with a meaningful proportion of those affected exhibiting virtually no hyperactive/impulsive symptoms. This subgroup may represent a distinct inattentive condition characterized by poor cognitive interference control and slow processing or output speed.  相似文献

This study examined the influence of perceived emotional intelligence (PEI) and intrusive thoughts on emotional responses following a stressful event. PEI was assessed on 144 participants using the Trait Meta-Mood Scale (TMMS). The TMMS assesses perceived ability to: (1) attend to moods (Attention); (2) discriminate clearly among moods (Clarity); and (3) regulate moods (Repair). The main purpose of this paper was to examine the relationship between PEI, intrusive thoughts, and adjustment to an acute stressor induced experimentally in the laboratory, on two separate days. Finally, we examined the relationship between PEI, Inhibition, and Empathy. Results indicated that Clarity influences emotional responses on Day 1, and Repair affects emotional responses on Day 2 indirectly via intrusive thoughts, which act as a mediator. Significant associations were obtained between the three factors of the TMMS with Empathy and Inhibition. These findings suggest that individuals with higher emotional Clarity and Repair will experience less negative emotional responses and intrusive thoughts after an acute stressor, which enables them to adapt more readily to the experience.  相似文献

Relatively little is known about the integration of people's fear-related dispositions and their expectations about stressful events. This research used information integration theory to examine how participants’ anxiety sensitivity and event expectancy are integrated to determine their social anxiety. Three studies were conducted—two with university students and one with anxiety clinic patients—in which participants were presented with multiple scenarios of a socially embarrassing event, each representing a different degree of event probability, from which subjective expectancies were derived. Independent variables included anxiety sensitivity (low, moderate, high) and event expectancy (low, medium, high, no probability information). Participants were asked to indicate their anxiety (dependent measure) in each expectancy condition in this 3 × 4 mixed, quasi-experimental design. The results of all three studies strongly suggest that anxiety sensitivity and event expectancy are integrated additively to produce social anxiety. Additional results and their implications for the treatment of anxiety-related disorders are also discussed.  相似文献

ABSTRACT

Background: The general consensus that cognitive abilities decline with advancing age is supported by several studies that have reported that older adults perform more poorly on multiple tests of cognitive performance as compared to younger adults. To date, preventive measures against this cognitive decline have been mainly focused on dietary, physical, and lifestyle behaviors which could allow older adults to maintain their cognitive abilities into late life. However, much less stress has been laid on evaluating meditation as a preventive measure in such cases in spite of the fact that the role of meditation on attention has been proved in several studies. In the current study, we extend this preliminary idea, examining the practice of concentrative meditation and the differences in the cognitive performance of older adults who have or have not employed this practice long term. Methodology: This was a cross-sectional study comparing the cognitive performance of meditators and non-meditators in the geriatric age group. Twenty (age > 55 years) long-term practitioners of Vihangam Yoga meditation (>10 years of practice) were recruited in the present study and were applied six paper–pencil neuropsychological tests for assessment of short-term memory, perceptual speed, attention, and executive functioning. The tests used were: (1) the Digit Span test, (2) the Stroop Color Word test, (3) the Trailmaking test, (4) the Letter Cancellation Task, (5) the digit symbol substitution test, and (6) the Rule Shift Card Test. All the tests were also applied to 20 age- and education-matched geriatric adults who have not practiced the meditation technique. Results: Vihangam Yogis showed significantly better performances in all these tests of attention (p < .05) except for the digit backward test, where a trend (p = .08) was found in favor of meditators. Conclusion: Long-term Vihangam Yoga meditators have superior cognitive abilities than non-meditators in the old age group. This technique should be studied further for its ability to prevent age-related cognitive decline.  相似文献

ABSTRACT

The exponential growth in information resources and the new demands of the information age have put increasing demands upon faculty and students to access appropriate information quickly, to process that information with critical thinking skills, and to communicate both verbally and in writing a product that is practical, interesting, and meaningful. The job of teaching of research methods must include the integral components of an information literacy program. Students need to be encouraged to expertly retrieve the information required for the writing of a paper. They must be helped to think critically, synthesizing ideas and concepts from the numerous information sources.

It is vital that the faculty and librarian at Seminary of the East work together to develop a comprehensive information literacy program that is not only supported by both faculty and library staff, but periodically evaluated to validate the program and to measure its progress in addressing the information literacy needs of both students and faculty.  相似文献
