Students with developmental disabilities may not have the necessary skills or the same opportunities to access multimedia-based leisure materials as their typical peers. Portable multimedia devices such as the iPod Touch® may provide them with a useful tool for accessing age-appropriate leisure material. The present study examined the feasibility of teaching 3 students with developmental disabilities to independently operate an iPod to watch age-appropriate entertainment videos. A delayed multiple-probe design across participants was implemented with baseline, intervention, fading, and follow-up phases. Video modeling and least-to-most response prompting were successfully used to teach these 3 students to operate an iPod Touch® to watch preferred videos without adult assistance. The results complement previous findings supporting the use of video modeling as an instructional strategy and add to the literature by using portable multimedia devices as assistive technology for teaching an age-appropriate leisure skill.  相似文献

The two‐step flow model of communication (Katz, 1957 ) suggests opinion leaders obtain critical information from the mass media and, in turn, communicate this information to interpersonal contacts such as friends, family and co‐workers. It is suggested that religious leaders (RLs) may serve as opinion leaders on the topic of organ donation by debunking donation myths, promoting donation during worship services, or communicating the benefit of donation to families faced with the opportunity to participate in living or cadaveric donation. The current study examined the personal knowledge, experiences, and willingness to communicate about organ donation in a sample of RLs (N = 59) in Rochester, New York. Structured interviews were conducted in summer and fall of 2009 with a random sample of RLs. Results indicate a disparity between RLs' expressed personal support for donation and their engagement in donor registration. Approximately one‐quarter of RLs have spoken about donation during a religious service and many indicate their knowledge is not sufficient to discuss organ donation in detail. Results elaborate on how RLs may be trained to serve as opinion leaders in the promotion of organ donation. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

How internal categories influence how we perceive the world is a fundamental question in cognitive sciences. Yet, the relation between perceptual awareness and perceptual categorization has remained largely uncovered so far. Here, we addressed this question by focusing on face perception during subliminal and conscious perception. We used morphed continua between two face identities and we assessed, through a masked priming paradigm, the perceptual processing of these morphed faces under subliminal and supraliminal conditions. We found that priming from subliminal faces followed linearly the information present in the primes, while priming from visible faces revealed a non-linear profile, indicating a categorical processing of face identities. Our results thus point to a special relation between perceptual awareness and categorical processing of faces, and support the dissociation between two modes of information processing: a subliminal mode involving analog treatment of stimuli information, and a supraliminal mode relying on discrete representation.  相似文献

We present the first steps in the validation of an observational tool for father-mother-infant interactions: the FAAS (Family Alliance Assessment Scales). Family-level variables are acknowledged as unique contributors to the understanding of the socio-affective development of the child, yet producing reliable assessments of family-level interactions poses a methodological challenge. There is, therefore, a clear need for a validated and clinically relevant tool. This validation study has been carried out on three samples: one non-referred sample, of families taking part in a study on the transition to parenthood (normative sample; n = 30), one referred for medically assisted procreation (infertility sample; n = 30) and one referred for a psychiatric condition in one parent (clinical sample; n = 15). Results show that the FAAS scales have (1) good inter-rater reliability and (2) good validity, as assessed through known-group validity by comparing the three samples and through concurrent validity by checking family interactions against parents’ self-reported marital satisfaction.  相似文献

Parents of individuals with autism spectrum disorders (ASD) often experience stressors associated with caring for their child. These stressors can cause considerable distress for families, which at times can develop into full blown crisis, and it is important that professionals be able to quickly identify when families are approaching or are in crisis to respond appropriately. The current study presents an initial attempt at measuring the subjective experience of crisis in 164 caregivers of people with ASD through a single item instrument, the Brief Family Distress Scale. The BFDS was negatively correlated with helpful coping mechanisms (family hardiness, and parent empowerment), and positive adjustment (caregiver quality of life and positive parenting experiences), and positively correlated with known stressors (severity of aggressive behavior, negative life events) and problematic coping and outcomes (caregiver burden, worry, mental health problems). As expected, caregivers at Marked levels of distress (approaching or in crisis) were significantly different from caregivers at lower levels of distress in nearly all of the dependent variables. Having a quick way of measuring where families are in terms of distress and crisis can be helpful for researchers and clinicians alike.  相似文献

This study aims to reveal correlates of depressive and anxiety symptoms among the Turkish caregivers of leukemic children (n?=?100). The effects of demographic variables, satisfaction of the basic needs, performance on daily activities, and coping strategies on outcome variables were investigated by hierarchical regression. Accordingly, older age, lower reported income, higher number of other children to be looked after, lower levels of satisfaction of basic needs, and more use of emotion focused coping were associated with higher levels of both depressive and anxiety symptoms. Moreover, caregivers with lower education reported more depressive symptoms, and higher performance on daily activities predicted more anxiety symptoms.  相似文献

The purpose of this study was to investigate whether patients with multiple sclerosis (MS) and their partners show adversarial growth and to examine which psychological and disability variables contribute to this in patients and their partners. The study also investigated the relationship between growth and distress. Seventy-two patients with MS and their partners provided demographic information and completed measures of posttraumatic growth, illness perceptions, depression, cognitive function and disability. Both patients and partners showed adversarial growth, with patients reporting significantly higher growth than partners. The only significant predictor for patient growth was partner growth, and vice versa. Dissimilarity in illness representations between patients and their partners on the consequences of MS dimension, patient mood and patient growth accounted for significant variance in partner growth. The findings support the idea of a ‘communal search for meaning’ where patients and their partners experience the trauma of having a chronic illness and subsequently find positive aspects together.  相似文献

This paper presents data concerning culturally prescribed gender traits and their influence on bullying/victimization problems and aggressive tendencies from a wide sample of 1,654 Spanish adolescents. The aims of this study were to clarify the effect of masculine traits on male and female secondary students’ aggression, and also to explore the role of feminine traits in either the inhibition of aggression or the use of more covert forms. Results show that masculine stereotypical traits are related more strongly with bully perpetration, proneness to aggression and experience of anger and hostility in both sexes. In contrast, traditional feminine traits are negatively related with bullying perpetration and proneness to aggression. However, feminine traits are linked to male students’ victimization. Results are discussed in the light of previous findings and are taken into consideration in the design of intervention practices in secondary schools.  相似文献
