The aim of this study is to explore reasons for and against prenatal testing and termination for a range of conditions in
women from two different ethnic backgrounds. A total of 19 Pakistani and European women in West Yorkshire, UK, who either
had a child with a genetic condition or had terminated a pregnancy for one, completed a questionnaire about their attitudes
regarding prenatal testing and termination for 30 different fetal conditions and were interviewed about their reasons for
their responses. There were more similarities than differences between the Pakistani and European white women. The most important
factor in most women’s decisions about termination of pregnancy was their perception of the quality of the life of a child
with the genetic condition, in particular, whether the child would be “suffering.” This was described as either physical suffering,
as a result of medical treatment, or as emotional suffering, as a result of psychological and/or social factors. These findings
highlight the need for detailed information about the potential quality of life for the child and the child’s family to enable
parents to make informed choices, particularly the extent to which the child is likely to suffer, the nature of such potential
“suffering” and the extent to which the child could lead a “normal” life. The findings also challenge stereotypes about cultural
differences in attitudes about termination of pregnancy. 相似文献

The syntactic devices of subject-verb-object word order, regular plurals, and subject-verb agreement differ in age of acquisition
and susceptibility to error within language-disordered populations. In the present article, the performance of adults on a
grammaticality judgment task is used to explore whether such differences are related to working memory (both in terms of an
externally imposed load and individual differences in capacity) and phonological ability. The results show that word order,
the earliest acquired and most resilient device, is not affected by load, memory span, or phonological ability. Plurals are
affected marginally by load and significantly by phonological ability. Agreement, the last acquired and least resilient device,
is affected by load, memory span, and phonological ability. Thus, consistent with a processing-based explanation, later acquired
and less resilient devices have higher working memory and phonological demands. 相似文献

Three experiments investigated whether study choice was directly related to judgments of learning (JOLs) by examining people’s
choices in cases in which JOLs were dissociated from recall. In Experiment 1, items were given either three repetitions or
one repetition on Trial 1. Items given three repetitions received one on Trial 2, and those given one repetition received
three on Trial 2—equating performance at the end of Trial 2, but yielding different immediate Trial 2 JOLs. Study choice followed
the “illusory” JOLs. A delayed JOL condition in Experiment 2 did not show this JOL bias and neither did study choice. Finally,
using a paradigm (Koriat & Bjork, 2005) in which similar JOLs are given to forward and backward associative pairs, despite
much worse performance on the backward pairs, study choice again followed the mistaken JOLs. We concluded that JOLs—what people
believe they know—directly influence people’s study choices. 相似文献

The aim was to assess the self-efficacy and health outcomes of an adopted Arthritis Self-Management Programme (ASMP) among osteoarthritic knee sufferers in Hong Kong at 1 year. An experimental study with 95 participants assigned randomly to the intervention (n=45) or control group (n=50). Seventy-seven (81.1%) participants joined at least one out of three follow-ups in the 12 month period. Participants in the intervention group received a 6-week ASMP with an added exercise component in two general clinics. Outcome measures included arthritis self-efficacy (ASE) and health outcomes including pain and fatigue rating, self-rated health, daily activities limitation and number of unplanned arthritis-related medical consultations. Mean change (12 months minus baseline) and the effect size of the outcome measures were calculated by Mann-Whitney U test and nQuery Advisor 4.0. At 12 months, there were significant reductions of current pain (p=0.0001), pain at night (p=0.001), pain during walking (p=0.01) and number of unplanned arthritis-related medical consultations (p=0.03) and a significant increase in ASE for pain (p=0.01) and other symptoms (p=0.02) and self-rated health (p=0.04) among the intervention group but not for the control group. However, there were similarities in outcome measures of pain while switching from a sitting to a standing position, fatigue rating and physical functional limitation (p=0.15; p=0.22 and p=0.91, respectively) for both groups. Our findings add to the evidence that the modified arthritis empowering programme improved perception of control of osteoarthritis and three health outcomes after 12 months of treatment. 相似文献

Client engagement is an essential yet challenging ingredient in effective therapy. Engaged clients are more likely to bond
with therapists and counselors, endorse treatment goals, participate to a greater degree, remain in treatment longer, and
report higher levels of satisfaction. This study explored the process of engaging high-risk youth and their parents in a unique
home-based family therapy intervention. Qualitative interviews were conducted with 19 families who completed family therapy
sessions that included a core component aimed at increasing treatment engagement. Parents’ and youths’ perceptions of engagement
suggest the importance of developing therapeutic alliance with therapists, who facilitated building a shared alliance among
family members. Implications for improving client engagement are discussed within the context of alliance building with the
therapist and among family members. 相似文献

The goal of this study was to explore the ability to discriminate languages using the visual correlates of speech (i.e., speech-reading). Participants were presented with silent video clips of an actor pronouncing two sentences (in Catalan and/or Spanish) and were asked to judge whether the sentences were in the same language or in different languages. Our results established that Spanish-Catalan bilingual speakers could discriminate running speech from their two languages on the basis of visual cues alone (Experiment 1). However, we found that this ability was critically restricted by linguistic experience, since Italian and English speakers who were unfamiliar with the test languages could not successfully discriminate the stimuli (Experiment 2). A test of Spanish monolingual speakers revealed that knowledge of only one of the two test languages was sufficient to achieve the discrimination, although at a lower level of accuracy than that seen in bilingual speakers (Experiment 3). Finally, we evaluated the ability to identify the language by speech-reading particularly distinctive words (Experiment 4). The results obtained are in accord with recent proposals arguing that the visual speech signal is rich in informational content, above and beyond what traditional accounts based solely on visemic confusion matrices would predict. 相似文献

Two investigations on how humans perceive information from visually rendered complex objects, such as military icons (glyphs) were conducted. A signal detection theory framework was employed to evaluate the sensitivity and specificity of human subject performance. The 6 adults tested showed that as complexity increased, their accuracy in performance decreased. Study 1 showed that complex dimensions (features) could not be assigned arbitrarily. Study 2 developed a rank ordering for features of an iconic object. 相似文献

Replies to comments by R. J. Griffore and D. A. Newman et al on the author's original article on test validity and cultural bias in racial-group assessment. Helms notes that, given that within-group variance exceeds between-groups variance, racial groups are probably simulating a psychological construct that is more strongly related to individuals' test scores than to their respective racial group's mean test scores. Therefore, models of individual differences, such as her Helms individual-differences (HID) model, that remove construct-irrelevant racial variance, are needed to make the testing process fair at the level of individual African American, Latino/Latina American, and Native American test takers. Her HID model is intended to focus attention on identifying the factors responsible for the racial-group-level differences and, thereby, assist test users to look beyond presumed physical appearance (e.g., racial-group designations) for explanations of individuals' cognitive abilities, knowledge, or skills test scores. 相似文献
