The study objective was to compare breast cancer screening practices, lifestyle behaviors and psychological distress among 640 women initiating BRCA1/2 testing to those among 9,498 similarly-aged women from the general population. Health behaviors and psychological distress were reported in a self-administered questionnaire at pre-test genetic counseling. Regression analyses indicate that high-risk women were more frequently performing breast cancer screening and, in the case of those previously diagnosed with cancer, were more likely to be non-smokers and physically active than women from general population. However, women initiating BRCA1/2 testing were significantly more distressed than controls. Globally, high-risk women seemed to be well informed about recommendations for women who are at high risk and to have access to screening adapted to their risk level. Given their significant psychological distress, providing minimal psychosocial support to all women undergoing BRCA1/2 testing at pre-test genetic counseling is relevant. 相似文献

We defined and measured a dimension of religiosity frequently invoked in end-of-life (EOL) research—deference to God’s Will
(GW)—and examined its relationship to preferences for life-prolonging treatments. In a 35-min telephone interview, 304 older
men and women (60 +) were administered the 5-item GW scale, sociodemographic questions, three attitude items regarding length
of life, and measures of two health indices, depression, and life-prolonging treatment preferences. The GW scale demonstrated
internal consistency (Cronbach’s alpha = .94) and predictive and discriminant validity. Higher scores indicative of greater
deference to GW were associated with stronger life-prolonging treatment preferences in poor-prognosis scenarios. Implications
for the role of religiosity in medical decision-making are discussed. 相似文献

ABSTRACT— Spatial imagery may be useful in such tasks as interpreting graphs and solving geometry problems, and even in performing surgery. This study provides evidence that spatial imagery is not a single faculty; rather, visualizing spatial location and mentally transforming location rely on distinct neural networks. Using 3-T functional magnetic resonance imaging, we tested 16 participants (8 male, 8 female) in each of two spatial imagery tasks—one that required visualizing location and one that required mentally rotating stimuli. The same stimuli were used in the two tasks. The location-based task engendered more activation near the occipito-parietal sulcus, medial posterior cingulate, and precuneus, whereas the transformation task engendered more activation in superior portions of the parietal lobe and in the postcentral gyrus. These differences in activation provide evidence that there are at least two different types of spatial imagery. 相似文献

This study explored how domestic cats perform in a horizontal string-pulling task to determine whether they understand this
case of physical causality. Fifteen cats were tested on their ability to retrieve an unreachable food treat in three different
set-ups: (a) a single baited string, (b) two parallel strings where only one was baited and (c) two crossed strings where
only one was baited. All cats succeeded at pulling a single string to obtain a treat, but none consistently chose the correct
string when two strings were parallel. When tested with two crossed strings one cat chose the wrong string consistently and
all others performed at chance level. There was no evidence that cats understand the function of the strings or their physical
causality. 相似文献

Focus groups are becoming a popular research approach that counselors can use as an efficient, practical, and applied method of gathering information to better serve clients. In this article, the authors describe focus groups and their potential usefulness to professional counselors and researchers. Practical implications related to the use of focus groups in counseling practice are discussed, and case examples are provided demonstrating how focus groups can be useful to counselors. 相似文献

Individuals who depressively ruminate about their current dysphoria tend to perseverate more than nonruminators. The goal of the current study was to determine whether such perseverative tendencies are associated with an inability to switch attention away from old to new information or with an inability to effectively inhibit the processing of previously relevant information. We used a task-switching paradigm that can distinguish between these two processes. Two experiments showed that depressive rumination is associated with a deficit in inhibiting prior mental sets. The second experiment also demonstrated that, in contrast to depressive rumination, angry and intellectual rumination are associated with difficulties in switching to a new task set, but not with inhibition of a prior task set. This study suggests that different forms of rumination are associated with different cognitive mechanisms and that both deficits may contribute to the perseveration that is associated with ruminative tendencies. 相似文献

This research examined the impact of defendant/complainant alcohol consumption and prior sexual history evidence on mock jurors' evaluations of a sexual assault trial. Participants (N = 196) were provided with a simulated trial in which the beverage consumption of both targets and the sexual history between them was manipulated. The results displayed a complex interplay between target beverage consumption and gender of participant. Typically observed gender effects—that is, women, compared to men, were more supportive of the complainant and less supportive of the defendant—was contingent upon target beverage consumption. Depending on how aggressive participants perceived the defendant to be, women were more sympathetic to the complainant, with this being contingent upon complainants' and defendants' beverage consumption. 相似文献

This paper investigates stress assignment in Dutch aphasic patients in non-word repetition, as well as in real-word and non-word reading. Performance on the non-word reading task was similar for the aphasic patients and the control group, as mainly regular stress was assigned to the targets. However, there were group differences on the real-word reading and non-word repetition tasks. Unlike the non-brain-damaged group, the patients showed a strong regularization tendency in their repetition of irregular patterns. The patients' stress error patterns suggest an impairment in retention or retrieval of targets with irregular stress patterns. Limited verbal short-term memory is proposed as a possible underlying cause for the stress difficulties. 相似文献

Yawning frequency and distribution in preterm and near term infants assessed throughout 24-h recordings 总被引:1,自引:0,他引:1
Yawning has been observed in foetuses and preterm infants. The aim of this study was to assess the frequency and the 24 h distribution of yawning in preterm infants.Twelve low-risk infants between 31 and 40 weeks of post-conceptional age (PCA) were continuously video-recorded for 24 h in their incubator. Spontaneous yawning was defined as opening of the mouth to its full extension in a dramatic stretch movement.The results showed that the rate of yawning across the 24-h period was 1.10/h. The highest incidence of yawns was in the waking motility pattern when compared to active sleep or quiet sleep motility patterns.Between 31 and 40 weeks, yawn incidence significantly decreased mainly during the day. The marked decrease in yawn frequency with age may be related to the development of circadian and homeostatic control of sleep and wake. 相似文献

The visual attention (VA) span is defined as the amount of distinct visual elements which can be processed in parallel in a multi-element array. Both recent empirical data and theoretical accounts suggest that a VA span deficit might contribute to developmental dyslexia, independently of a phonological disorder. In this study, this hypothesis was assessed in two large samples of French and British dyslexic children whose performance was compared to that of chronological-age matched control children. Results of the French study show that the VA span capacities account for a substantial amount of unique variance in reading, as do phonological skills. The British study replicates this finding and further reveals that the contribution of the VA span to reading performance remains even after controlling IQ, verbal fluency, vocabulary and single letter identification skills, in addition to phoneme awareness. In both studies, most dyslexic children exhibit a selective phonological or VA span disorder. Overall, these findings support a multi-factorial view of developmental dyslexia. In many cases, developmental reading disorders do not seem to be due to phonological disorders. We propose that a VA span deficit is a likely alternative underlying cognitive deficit in dyslexia. 相似文献
