We investigated the feasibility of using the Space Fortress (SF) game, a complex video game originally developed to study complex skill acquisition in young adults, to improve executive control processes in cognitively healthy older adults. The study protocol consisted of 36 one-hour game play sessions over 3 months with cognitive evaluations before and after, and a follow-up evaluation at 6 months. Sixty participants were randomized to one of three conditions: Emphasis Change (EC)--elders were instructed to concentrate on playing the entire game but place particular emphasis on a specific aspect of game play in each particular game; Active Control (AC)--game play with standard instructions; Passive Control (PC)--evaluation sessions without game play. Primary outcome measures were obtained from five tasks, presumably tapping executive control processes. A total of 54 older adults completed the study protocol. One measure of executive control, WAIS-III letter-number sequencing, showed improvement in performance from pre- to post-evaluations in the EC condition, but not in the other two conditions. These initial findings are modest but encouraging. Future SF interventions need to carefully consider increasing the duration and or the intensity of the intervention by providing at-home game training, reducing the motor demands of the game, and selecting appropriate outcome measures.  相似文献

Mechanisms of selective attention exert a powerful influence on visual perception. We examined whether attentional selection is necessary for generation of the vivid colours experienced by individuals with grapheme-colour synaesthesia. Twelve synaesthetes and matched controls viewed rapid serial displays of nonsense characters within which were embedded an oriented grating (T1) and a letter-prime (T2), forming a modified attentional blink (AB) task. At the end of the stream a coloured probe appeared that was either congruent or incongruent with the synaesthetic colour elicited by the letter-prime. When the prime was attended, synaesthetes showed a reliable effect of prime-probe congruency. In contrast, when the prime appeared at 350 ms following T1 (during the AB), the congruency effect was eliminated. Our findings suggest that focused attention is crucial for inducing letters to elicit colours in synaesthesia.  相似文献

Celebrated people often seem larger than life. In a series of experiments, and with observational data, we asked whether an association exists between regard for the action capabilities of soccer players and perceptual estimations of their size. Higher regard resulted in overestimations of size, and momentary modifications of apparent action capability resulted in overestimations or underestimations of size directly related to performance success or failure, respectively.  相似文献

This study examined predictors of attrition from a pediatric weight-control program in a low-income minority community and the potential usefulness of an orientation session to increase length of treatment. Participants were 342 children and adolescents (M age=13.0 years old; 54% female; 89% African American; M BMI=44.2, M BMI z-score=6.0) and their caregivers who attended FitMatters, a multidisciplinary cognitive-behavioral program focused on long-term participation. Those who attended an orientation session stayed in treatment significantly longer, but attrition was not affected by demographic factors, weight status, or psychological functioning. These results indicate that an orientation session that clearly delineates the structure of a program and expected attitudinal and behavioral requirements for the families may help align expectations, as well as more effectively identify families who are ready to make concerted efforts to change the family lifestyle in support of their obese children's efforts.  相似文献

Students Who Like and Dislike School   总被引:1,自引:0,他引:1  
The major goal of this study was to investigate relationships among levels of 341 secondary school students’ school satisfaction and various intrapersonal, interpersonal, and academic measures. The measures included the School subscale from the Multidimensional Students’ Life Satisfaction Scale (Huebner, 1994), Students’ Life Satisfaction Scale (Huebner, 1991), Children’s Hope Scale (Snyder et al. 1997), Behavioral Assessment System for Children (Reynolds & Kamphaus, 1992), self-perceived grade point average (GPA) and participation in extracurricular activities (SEAs). Students were placed into three groups based on their school satisfaction reports, including very low (lowest 20%), average (middle 30%), and very high (highest 20%) levels of school satisfaction. Students with very low school satisfaction differed from students with very high school satisfaction on all adjustment measures; students with very low school satisfaction also differed from students with average levels of school satisfaction on all measures, except the self-esteem measure. Relative to students reporting average levels of school satisfaction, students reporting very high satisfaction demonstrated significantly higher scores on measures of global life satisfaction, hope, internal locus of control, and GPA. Finally, only three students in the very high satisfaction group and nine students in the average satisfaction group reported clinical levels of psychological symptoms. In the very low satisfaction group, clinical levels of symptoms were reported by 30%, 22%, and 16% of the students on the Clinical Maladjustment, Personal Adjustment, and Emotional Symptoms Index, respectively. Implications for future research and educational practices are discussed.  相似文献

Resilience and emotion regulation are crucial for optimal psychosocial functioning in children. This study assessed whether a group-based intervention, the Resilience Builder Program (RBP), improved student report of emotion regulation when administered in elementary schools. Sixty-seven students aged 9–12 years (M = 10.50, SD =.74; 82.1% male, 98.5% ethnic/racial minority) were randomly assigned to receive the RBP intervention immediately or following a semester delay. Participants reported their emotional control using the How I Feel scale. Students who received the RBP reported a significant increase in their emotional control and a significant decrease in negative emotion compared to those students in the delayed treatment sample who had not yet received the intervention. Further, students indicated a strongly positive perception of the therapy.  相似文献

This study explores child and parent motivation at the start of a social skills training group program and its relationship with treatment outcome. A total of 59 children (aged 7–12) participated. Parents were more aware of, distressed by, and motivated to change the presenting problem than were their children. Greater parent awareness of their child’s difficulty making and keeping friends and perceived importance of their child learning ways to make and keep more friends significantly predicted more improved social skills. Increasing parents’ awareness and perceived importance of treating the presenting problem at the start of therapy may increase treatment effectiveness.  相似文献

Two studies explore the narrative construction of self-perceptions in conversational storytelling among pairs of same-sex friends. Specifically, the studies examined how listener behavior can support or undermine attempts to self-verify in personal storytelling. In two studies (n=100 dyads), speakers told attentive, distracted, or disagreeable (Study 1 only) friends about a recent experience. Distracted, but not disagreeable, friends tended to undermine participants' attempts to verify their self-perception of being interested in an activity (Study 1) or their self-perception that an event was typical for them (Study 2). These results support the notion that friends can be an important source of influence on self-perceptions and, perhaps surprisingly, suggest that responsiveness from friends, rather than agreement per se, may be crucial for supporting self-verification processes.  相似文献

Prognostication, the process offormulating and communicating a prognosis, isno longer considered by most physicians to bean essential task in caring for patients withserious illness. Because of this fact, it isnot surprising to find that when physiciansattempt to engage in prognostication, they doit poorly. What may be surprising to thoseoutside the medical community is the extent towhich professional norms have developed whichactively discourage physicians from engaging inprognostication. This article explores thecauses of this state of affairs and thejustifications offered for it. The conclusionis reached that physicians have a professionalresponsibility to competently engage inprognostication based upon the doctrine ofinformed consent, and that a failure or refusalto do so has not only potential legalramifications, but serious negativeimplications for many of the core issues inbioethics, such as the use of advancedirectives, palliative medicine, and medicalfutility.  相似文献
