Burden of care, expressed emotion (EE), causal attributions, and salivary cortisol were assessed in 100 carers of patients with Alzheimer's disease. Forty-one carers were rated high EE, which was associated with higher scores of carer distress and strain, and greater reports of noncognitive features in the patient, but not with cortisol levels. High EE carers made more attributions personal to, and controllable by, the patient for negative events. Critical carers made more attributions of the patient's behavior that was idiosyncratic. Warmth toward the patient was associated with the opposite of this pattern. Overinvolved carers made attributions of the patient's behavior to causes external to the patient and internal to themselves. Cortisol levels were associated with self-reports of strain and distress.  相似文献

Research in education, psychology, and neuroscience motivates a hypothesis that learning takes time. Support for the hypothesis was found in four replications of an upper level undergraduate course in which the material and activities for 50% of the topics were delivered over the World-Wide Web. Computer records were correlated with three types of test questions: multiple-choice, short-answer, and open-ended essay questions. Positive and significant correlations with time were observed for 33% of the correlations involving multiple-choice questions, 13% of those involving short-answer questions, and 60% of those involving open-ended essay questions. An estimate of the common underlying correlation, ρ, equal to .35 for the four replications was significant. The data also revealed generally low overall study times and a maladaptive pattern of “cramming” before tests instead of distributing practice. In the Discussion section, we argue that computer study times can be used as a predictor of subsequent test performance, which is a measure of student learning.  相似文献

The effect of phonological similarity amongst list items on the modality effect was investigated in free recall with distraction activity interpolated before and after each list word. In Experiment 1 the distractor activity involved counting backward silently mouthing each number, and the modality effect was drastically attenuated by high similarity. This outcome is comparable with that found in immediate recall, and it is consistent with an echoic memory interpretation. In Experiment 2 the same backward-counting task was performed with each number being vocalized, and the modality effect was unaffected by phonological similarity. This outcome leads to the stronger conclusion that, under those conditions at least, the modality effect cannot be echoic. Implications of these findings for general theoretical accounts of the modality effect are discussed.  相似文献

Our aim was to build a model delineating the relationship between attitudes toward suicide and suicidal behavior and to assess equivalence by applying the model on data from different countries. Representative samples from the general population were approached in Sweden, Norway, and Russia with the Attitudes Toward Suicide (ATTS) questionnaire. Data on experience of suicidal behavior among significant others and self‐reported suicidal expressions were also collected. Structural equation modeling resulted in gender and country specific models where experience of suicidal behavior among significant others and self‐reported suicidal expressions earlier in life predicted attitudes, and attitudes predicted current suicidal expressions. The models included the attitude factors acceptance of suicide, condemnation, and preventability; age and level of education were also incorporated. The different models reveal possible ways to better understand gender and culture‐specific paths between attitudes and suicidal behaviors, and their relevance in a suicide prevention context is considered.  相似文献

The most important role in the recognition and categorization of predators (as well as other animals) is usually attributed to so-called key features. Under laboratory conditions, we tested the role of yellow eyes (specific for the genus Accipiter in European raptors) and hooked beak (common for all European birds of prey) in the recognition of the sparrowhawk (Accipiter nisus) by untrained great tits (Parus major) caught in the wild. Using wooden dummies, we interchanged either one of these potential key features or the body of the sparrowhawk (predator) and domestic pigeon (harmless bird). The tested tits showed three types of behaviour in the presence of the dummies: fear, interest without fear, and lack of interest. Eye interchange lowered fear of the sparrowhawk, but did not cause fear of the pigeon. Beak interchange did not lower fear of the sparrowhawk. Eye interchange caused increased interest in both species. Thus, a specific sparrowhawk feature is necessary for correct sparrowhawk dummy recognition but a general raptor feature is not. On the other hand, a specific sparrowhawk feature on a pigeon dummy is not enough to prompt sparrowhawk recognition. Thus, key features play an important, but not exclusive, role in predator recognition. An increased interest in some of the modified dummies implies that the tits have a general concept of a sparrowhawk. The individual variability in behaviour of tits is discussed.  相似文献

The perspective of trunk deformity is a matter of special concern for adolescent idiopathic scoliosis (AIS) patients. No research group has ever reported interviewing patients and their parents regarding differences in perception of body appearance in the course of Cheneau brace treatment. We aimed to investigate the level of agreement in the field of concerns and perceptions of spinal appearance in relation to brace- and scoliosis-related data between parents and female patients with AIS, treated with a Cheneau brace, by means of the Spinal Appearance Questionnaire-pl (SAQ-pl). In this cross-sectional study forty-one pairs of parents and female patients with AIS were asked to separately complete the Polish versions of the Spinal Appearance Questionnaire-pl patient form (SAQ-pl patient form) and the SAQ-pl parent form. Age of patients was 13.60 years SD 1.60 (range 10–17). Patients scored 2.70 (SD 0.60) and parents scored 2.70 SD 0.60 in the total score of the SAQ-pl. The study groups do not differ significantly in regards to the SAQ-pl results. The percentage of consistent answers on SAQ-pl items ranges from 34.10 % (item 20) to 78 % (item 8). Height, age and brace-wearing time per day, were significantly related to the differences in the patient-parent General perception of body shape (r s  = ?0.51, r s  = ?0.34, r s  = 0.36, respectively). Parents and female patients with AIS have similar concerns and perceptions of spinal appearance. The discrepancies in General perception of spinal appearance between parents and AIS females decrease with age of patient. Parental emotional support may contribute to minimizing the risk factors of psychological impairment, especially in late adolescents with AIS.  相似文献
