The clinical staff of a large metropolitan nursing home was surveyed about their religious practices, the degree to which they saw their work as a ministry, and the meaning they obtain from being caregivers. Age, race, gender, education, and various other measures were also taken. As hypothesized, religiosity made a significant positive contribution to participants' belief their work was a ministry to those in need. Multiple regression revealed that African American and older staff scored significantly higher on both dependent variables, whereas Caucasians were significantly less likely to view their work as ministry. Staff who worked with long-term patients derived significantly more meaning from their work, but they were no more likely to see it as ministry. Religiosity appears to enhance the meaning caregivers get from their work, and this may be beneficial to patients. Further research may identify other factors that enhance the meaning caregivers get from their work.  相似文献

In the current study, 138 college females were randomly assigned to four media exposure conditions based on the presence or absence of an attractive person (fashion model) and the presence or absence of an appearance-related product. Outcome measures consisted of visual analogue ratings of multiple body image and mood variables. The results revealed a significant main effect for person, indicating that the presence of a model increased levels of body dissatisfaction and negative mood. No product effect emerged and there was no significant interaction between person and product. These findings suggest that the appearance priming effect of media exposure on body dissatisfaction and mood is specific to a person stimulus, with no additional effect promoted by a generic appearance-relevant stimulus.  相似文献

The degree of perceived force involved in squeezing a handgrip dynamometer is shown to grow as a power function of the force of isometric contraction and also as a power function of the duration of the squeeze. The exponent for force turns out to be more than twice that for duration. These two power functions are able to predict measurements of muscle endurance, i.e., of the maximum length of time that contraction of any constant level of force can be sustained.  相似文献

The relation of brightness to duration and luminance has been studied by matching one brightness to another and also by matching numbers to brightnesses (magnitude estimation). The two methods concur in confirming certain well-known visual functions: Bloch’s law, the Broca-Sulzer effect, and the shift of the Broca-Sulzer enhancement to shorter durations when luminance increases. It is shown that the shift with luminance requires the exponent of the power function for short-flash brightness to be larger than the exponent for stimuli of longer duration. An attempt is made to analyze some of the reasons why the procedure advocated by Graham may not give comparable results.  相似文献

Cross-modality matches have been made between loudness and ten other perceptual continua. The matching functions are all power functions. When the exponent values of the matching functions are divided by the exponent values previously determined for the various continua, the quotients predict values for the loudness exponent. A tentative consensus suggests that the loudness exponent may be about 0.64.  相似文献

ON THE NEW PSYCHOPHYSICS   总被引:1,自引:0,他引:1  
A discussion of problems and methods in modern psychophysics is presented. A distinction is made between prothetic and metathetic continua, and between ratio scales, category scales and what are called confusion scales. The paper includes a survey of some scaling experiments and reports the exponents of a number of power functions describing the relation between stimulus magnitude and subjective magnitude.  相似文献

In Experiment I, three groups of 20 Ss each were exposed to a light of 550 mμ (yellowish-green) for 60 sec and then viewed a random sequence of wavelengths with instructions to respond only to the original color. The instructions given the three groups were worded differently in an attempt to vary the strength of a set-to-discriminate assumed to be created by this procedure. The three groups produced similar gradients, each with a peak of responding at 540 mμ, in agreement with Kalish's (1958) published gradient for the 550 mμ standard stimulus value. It was suggested that the nature of the task is such that a strong discriminatory set is produced regardless of the wording of the instructions.

A temporal analysis of the gradient as it develops during the testing revealed that initially the peak of responding occurs at 550 mμ; but as testing progresses, it shifts gradually in the direction of the shorter wavelengths (purer greens). Experiment II was performed to test the generality of the phenomenon of regression to the primary color. Two groups of 20 Ss each were tested for generalization following exposure to 510 mμ (bluish-green) and 525 mμ (pure green), respectively. We predicted that the 510 mμ gradient would reveal a progressive shift toward the longer wavelengths (purer greens), whereas the 525 mμ gradient would show no tendency to shift. The results were strikingly in accord with these predictions.

We concluded that although a physiological process could not be ruled out, the verbal labeling of the standard stimulus value may well be responsible for the regression of the gradient toward the primary color.

Controversy exists as to whether, compared to young adults, older adults are more, equally or less likely to make linguistic predictions while reading. While previous studies have examined age effects on the prediction of upcoming words, the prediction of upcoming syntactic structures has been largely unexplored. We compared the benefit that young and older readers gain when the syntactic structure is made predictable, as well as potential age differences in the costs involved in making predictions. In a self-paced reading study, 60 young and 60 older adults read sentences in which noun-phrase coordination (e.g. large pizza or tasty calzone) is made predictable through the inclusion of the word either earlier in the sentence. Results showed a benefit of the presence of either in the second half of the coordination phrase, and a cost of the presence of either in the first half. We observed no age differences in the benefit or costs of making these predictions; Bayes factor analyses offered strong evidence that these effects are age invariant. Together, these findings suggest that both older and younger adults make similar strength syntactic predictions with a similar level of difficulty. We relate this age invariance in syntactic prediction to specific aspects of the ageing process.  相似文献

Shame, guilt, and ego development are conceptually interrelated constructs, yet their empirical relations have not yet been examined. Further, these constructs have not yet been mapped onto the widely used Five-Factor Model. In Study 1, relations were examined between these three domains within a sample of Australian university students. Two types of guilt were distinguished, Empathic Guilt (associated with Agreeableness) and Anxious Guilt (associated with Neuroticism). The relationship between Shame and Ego Level was found to be curvilinear, with Shame greatest for persons at intermediate stages of ego development. In Study 2, relations between ego development and the Five-Factor Model were further examined. Across both studies, Ego Level was best predicted from Conscientiousness among men and from Openness among women. Relations between Ego Level, proneness to shame and guilt, and the five factors were typically modest, suggesting that these represent complementary approaches to the study of personality.  相似文献
