The aim of the present study was to identify relevant variables associated with Quality of Life (QoL) in older adults. Older
adults, up to 60 years old, were interviewed. Subjects were recruited through convenience sampling. 339 paticipants, who were
stratified by gender, age, and subjective perception of health and illness, answered questions on sociodemographic issues,
QoL (WHOQOL-100) and depressive symptomathology (Beck Depression Inventory—BDI). The multiple linear regression analysis showed
associations of overall perception of QoL with depression levels, subjective perception of health status and gender. The individual
analysis of each domain concluded that depression levels are correlated to all QoL domains, while health status was associated
with physical, psychological, independence level and social relationship domains. Other variables were also assessed. The
assessment of older adults concerning their QoL perceptions is associated with gender, age, marital status, social class,
literacy rate, perception of health, and more substantially associated with depressive symptoms levels. Nevertheless, some
limitations of this study and further ones are suggested. 相似文献

Strong cross-modal interactions exist between visual and auditory processing. The relative contributions of perceptual versus decision-related processes to such interactions are only beginning to be understood. We used methodological and statistical approaches to control for potential decision-related contributions such as response interference, decisional criterion shift, and strategy selection. Participants were presented with rising-, falling-, and constant-amplitude sounds and were asked to detect change (increase or decrease) in sound amplitude while ignoring an irrelevant visual cue of a disk that grew, shrank, or stayed constant in size. Across two experiments, testing context was manipulated by varying the grouping of visual cues during testing, and cross-modal congruency showed independent perceptual and decision-related effects. Whereas a change in testing context greatly affected criterion shifts, cross-modal effects on perceptual sensitivity remained relatively consistent. In general, participants were more sensitive to increases in sound amplitude and less sensitive to sounds paired with dynamic visual cues. As compared with incongruent visual cues, congruent cues enhanced detection of amplitude decreases, but not increases. These findings suggest that the relative contributions of perceptual and decisional processing and the impacts of these processes on cross-modal interactions can vary significantly depending on asymmetries in within-modal processing, as well as consistencies in cross-modal dynamics. 相似文献

Pharmacotherapy follow-up (PTF) is the professional practice in which the pharmacist takes charge of the needs of the patients related to their drugs. OBJECTIVE: To validate a questionnaire to measure the ASE psychosocial determinants (attitude, social influence, self-efficacy) of PTF and the Prochaska & DiClemente's stage of change in Spanish community pharmacists. METHOD: Postal survey to 482 Asturian community pharmacists (test and retest). Validity was estimated in 134 pharmacists answering the test. Stability was estimated in 85 pharmacists answering the test and retest. Exploratory factorial analysis was used to investigate construct validity and produced 4 factors and 104 items. Those factors had high reliability (Cronbach's a between 0,87 and 0,96). DISCRIMINANT VALIDITY: Pharmacists in extreme stages of change showed significant differences of attitude, motivation and self-efficacy. Repeatability was good and the questionnaire appears valid and reliable. 相似文献

A perceptually filled-in surface, such as occurs during sustained attention to a peripheral stimulus (Troxler fading), can be functionally equivalent to a physically presented stimulus. Observers failed to detect probes that were presented in the location of a filled-in surface that had the same surface attributes as the probes; this was true even though, physically, the probes contrasted with the background. Probe stimuli with surface characteristics different from those of the filled-in surface were detected more often, though not quite as often as when there was no filled-in surface. Together, these findings support the idea that there are two components in perceptual filling: a neural filling-in component and a sustained-attention component, which actively suppresses perceptual processing at the filled-in location. More broadly, they illustrate the interplay of basic visual mechanisms in the creation and representation of visual surfaces and in the coding and detection of changes to these surfaces. 相似文献

Inhibition of return (IOR) has long been viewed as a foraging facilitator in visual search. We investigated the contribution
of IOR in a task that approximates natural foraging more closely than typical visual search tasks. Participants in a fully
immersive virtual reality environment manually searched an array of leaves for a hidden piece of fruit, using a wand to select
and examine each leaf location. Search was slower than in typical IOR paradigms, taking seconds instead of a few hundred milliseconds.
Participants also made a speeded response when they detected a flashing leaf that either was or was not in a previously searched
location. Responses were slower when the flashing leaf was in a previously searched location than when it was in an unvisited
location. These results generalize IOR to an approximation of a naturalistic visual search setting and support the hypothesis
that IOR can facilitate foraging. The experiment also constitutes the first use of a fully immersive virtual reality display
in the study of IOR. 相似文献

Although we are far from a universally accepted pattern of impaired function at altitude, there is evidence indicating motor, perceptual, memory and behavioural deficits in adults. Even relatively low altitudes (2500 m) may delay reaction time, and impair motor function. Extreme altitude exposure (>5000 m) may result in more pronounced impairment that can persist after returning to the lowlands. Research into the effects of altitude exposure earlier in development is lacking by comparison. Un-acclimatized children can suffer from acute mountain sickness, and, in native populations born at altitude, subtle cognitive and behavioural deficits suggest incomplete adaptation to hypoxia. The study of neurobehavioural functioning at altitude may provide important information about the effects of clinical hypoxia on the human brain and behavioural development. 相似文献

A systematic review was undertaken of the literature on the use of the Internet and other information and communication technologies (ICT's) in the provision and support of religious and spiritual care in healthcare. Indexes such as Medline, PsychoINFO and Proquest Religion were searched. The review found little systematic study of the effectiveness of the Internet and other ICT's in religious and spiritual care. It is believed that the results of this review provide a basis for promise spiri care in the further explora of the potential and of ICT's for tual healthcare. 相似文献

Abstract-After the airplane attacks of September 11, 2001, in the United States, many Americans drove instead of flying, to avoid the risk of terrorism. As a result, there were extra car accidents in which many people died. This study tested whether a similar effect occurred in Spain after the train bombings of March 11, 2004, in Madrid. Data on train travel, highway traffic, and fatal highway accidents were analyzed for the months immediately following March 11. Results show that, like Americans, Spaniards avoided the dread risk of terror attacks, but unlike Americans, they did not confront the death risk of fatal accidents instead. A sociopolitical interpretation for these findings is offered. 相似文献

Selective Revision 总被引:1,自引:0,他引:1
We introduce a constructive model of selective belief revision in which it is possible to accept only a part of the input
information. A selective revision operator ο is defined by the equality K ο α = K * f(α), where * is an AGM revision operator
and f a function, typically with the property ⊢ α → f(α). Axiomatic characterizations are provided for three variants of selective
revision.
This revised version was published online in June 2006 with corrections to the Cover Date. 相似文献
