The purpose of this study was to demonstrate the applicability of Fitts' law in predicting the response duration of instruction-specific head movements for a person with severe multiple disabilities. Fitts' law is a motoric algorithm that calculates an index of difficulty (ID) for responses in relation to the variables of stimulus width and stimulus amplitude. Four functional tasks from the learner's current continuing education plans were targeted: photocopying, using a paint well, model painting, and communication symbol sequencing. For each of the four tasks, two sets of indices were calculated by (1) holding constant stimulus width while varying amplitude, and (2) holding constant stimulus amplitude while varying width. Results showed that response duration varied as a function of ID variation. 相似文献
Since blushing is difficult to detect in people with dark skin, their experience of blushing may differ fundamentally from people with fair skin. To investigate this issue, cheek temperature and forehead blood flow were measured in 16 Caucasians and 16 Indians during mental arithmetic and singing. Caucasians (particularly females) thought that they blushed more intensely than Indians, and also reported greater self-consciousness when singing. Vascular responses did not differ between groups. However, skin tone moderated the association between vascular responses and ratings of self-consciousness, blushing intensity, blushing propensity and fear of negative evaluation. These findings support the notion that the visibility of blushing influences the nature of emotions experienced in embarrassing social encounters. 相似文献
This article presents findings from a study of the psychometric properties of the Dyadic Adjustment Scale (DAS) with 63 Chinese-Americans. The analysis revealed high internal consistency for DAS scores. Coefficient alpha for the total DAS score was r = .93. Convergent validity was established with the Locke-Wallis Marital Adjustment Scale (LWMAT) (r = .87) and divergent validity by evidence of an inverse relationship with the Marital Disaffection Scale (MDS) (r = –.79). Correlations with each measure were found to be (p = 0.01). The result of factor analysis fail to support the presence of four separate subscales. Results show that the global DAS score is of potential utility with Asian samples. 相似文献
Mental timing studies may be influenced by powerful cognitive illusions that can produce an asymmetry in their rate of progress relative to neuronal timing studies. Both types of timing research are also governed by a temporal asymmetry, expressed by the fact that the direction of causation must follow time's arrow. Here we refresh our earlier suggestion that the temporal asymmetry offers promise as a means of timing mental activities. We update our earlier analysis of Libet's data within this framework. Then we consider the surprises which often occur on those rare occasions when neural timing experiments parallel mental timing work exactly. Together, these surprises and asymmetries prescribe a relentlessly meticulous and fully transparent exposition of timing methods, terms, and concepts which shuns plausible narratives, even when buttressed by rigorous formal models, unless guided by opposite empirical evidence. 相似文献
This teaching case illustrates the innovative application of an instructional technology modality, the WebQuest, in family
therapy training. It describes what a WebQuest involves, and how it can be used as a tool for developing critical thinking
and application of contemporary marriage and family therapy (MFT) theory to social and global issues. The authors discuss
the results of the survey and focus groups conducted to assess the value of this assignment from the students’ perspectives.
Results indicate that its application in a family therapy theories course fostered students’ awareness of global issues impacting
family life, integration of family therapy theories to serve children and families, creativity in developing their own intervention
models, and ability to discuss and integrate knowledge from different knowledge bases and perspectives. 相似文献
This study investigated; the behavioral adjustment and academic status of children with HIV infection through serial evaluations
over a ten-year period. The parents of children were assessed with Achenbach Child Behavior Checklist Parent Forms and the
children were administered the Woodcock-Johnson Tests of Academic Achievement at regular intervals as part of their treatment
in the HIV Program of a children’s hospital. Children with HIV were found to have behavioral adjustment within normal limits
over time. Aggressive behavior was noted to decrease over time. Academic achievement mirrored IQ status, unlike other studies,
which have reported poorer achievement than expected for IQ. Math skills appeared to improve over time. Thus, these findings
suggest children with HIV infection did not show significant behavioral disturbance across time, however, aggressive behavior
appeared to decrease. Academic achievement was stable over time. 相似文献
Previous suicide attempts are a leading risk factor for completed suicide. To identify specific characteristics of those at high risk for attempts, we investigated associations with socioeconomic status (SES). Data from the 2013 Korean Community Health Survey (KCHS) included adults who reported suicidal ideation (N = 220,245). Attempts in the past 12 months were assessed. Associations of demographic, socioeconomic, and suicide‐related behavioral factors were analyzed using multiple logistic regression. Among those with suicidal ideation, 862 (3.9%) had attempted suicide. After stratification by age and gender, results showed that low education and unemployed young adult men and women had significantly higher rates of attempts. The lowest income level was associated with significantly higher rates of attempts in only young adult women. Among those with the lowest and highest income, the association between ideation and attempts was attenuated, whereas it was enhanced among other income groups. 相似文献
Objective. This study explores (1) the motivations and challenges facing family caregiving for cancer in Singapore and (2) suggests a possible framework to guide culturally sensitive future work on caregivers.
Design. Twenty caregivers of patients being treated for cancer at a public hospital in Singapore were interviewed. A semi-structured interview format and inductive thematic analysis were used to analyse the data. Caregivers were asked about their motivations for caregiving and the challenges they faced.
Results. Caregivers’ motivations grouped into three categories: personal value and fulfilment, giving care because of societal expectations such as filial piety, and practical need. Challenges were grouped into interpersonal challenges, disclosure and finding balance. Caregivers with different primary motivations varied in their responses to these challenges. More autonomous caregivers cited learning points and reprioritised more effectively than less autonomous caregivers, who reported more internal conflict and less control over their situation.
Conclusions. In Singapore and Asia, sociocultural values of family caregiving are not uniformly experienced as positive, and may be burdensome for caregivers who give care primarily for extrinsic motivations. As family caregiving needs increase, targeted psychosocial support for caregivers with less autonomous behavioural orientations may pre-empt caregiver burnout and burden. 相似文献
A considerable amount of research in hope is driven by Snyder's (1994) model which proposes that hope is positively associated with agency thinking and pathways thinking. However, the current research suggests that hope as understood by the layperson (Hope) is only associated with agency thinking and not with pathways thinking. This was found over four studies using different agency and pathways variables, different Hope variables, different methods, and different cultures. Implications of these findings for Snyder's model are discussed. 相似文献
