Pastors' children have been thought to have more behavioral problems than other children since they face high expectations and are part of families that are often under public scrutiny. The purpose of this study was to describe the social competencies and behavioral problems of a national sample of pastors' children, aged 4–16, and to compare them to age and sex standardized norms. Data were obtained on 98 children from a random sample of 62 families, using the Child Behavior Checklist. Results indicate that scores for both boys and girls at each age grouping fell within the acceptable norms for both social competencies and behavioral problems.  相似文献

This paper presents some results of an in-depth interview study on the celibate experience of Roman Catholic priests. Twenty-four parish priests who were able and willing to talk about their celibacy were interviewed in five- to six-hour-long sessions. The purpose of the study was to gain more insight into the psychodynamics of being obliged to live a celibate life. Three varieties of celibate experience that we discovered in our research population will be presented. Also the problematic relationship between celibacy and mental health will be discussed.This research was partly supported by the Dutch Centre for Studies in Mental Health (KSGV).  相似文献

Our discussion begins with a consideration of the various types of religion and of guilt. Both religion and morality function in different ways from individual to individual. All these factors need to be taken into account before we can turn to treatment for the painful experience of guilt and bring about an improved self-esteem.  相似文献

In Phase 1 of this study, we asked 23 parents between the ages of 30 and 52 years and 26 children between the ages of 10 and 19 years to list effects of television and video games on children. A questionnaire was developed using the most frequently given responses (e.g., television influences children's aggressive behavior, verbal abilities, or time with friends). In Phase 2, this questionnaire was administered to different groups of parents and children and a control group of adults without offspring (N = 204) who were asked to rate the influence of each item on the questionnaire. Multivariate analyses of variance indicated that there were similarities and differences among the groups. For example, parents and other adults held similar beliefs about the influence of television, but parents held more positive beliefs about the influence of video games than the other adults. Children held more positive beliefs about the influence of television than parents, but parents and children held similar beliefs about the influence of video games.  相似文献

In the first experiment, 4 pigeons were each presented with a recurring sequence of four key colors followed by the delivery of grain (block clock). Once the rate of pecking had stabilized, three of the colors were replaced, during different series of sessions, by a darkening of the key. The rate of pecking was reduced within those segments of the interval between deliveries of food during which the key was dark; when the key was dark during the final portion of the interval, rates were reduced throughout the entire interval. In the second experiment, 3 new pigeons were exposed to a different sequence of colors, and the final stimulus was replaced in successive conditions by a novel color, a darkened key, and a restoration of the original color. The data indicated that darkening the key had a more severe, more extensive, and more persistent effect than did a mere change in color. These results suggest that it may be fruitful to conceptualize the autoshaping procedure as a special version of the block clock in which pecking is suppressed throughout the greater part of the interval by darkening the key. In the final condition, the same stimulus appeared in each of the last three portions of the interval. The rate of pecking was lower during the last two portions than when distinctive colors were presented, with the peak rate now appearing in the fifth of seven equal temporal components.  相似文献

In Part 1 of this paper, topics germane to the projective assessment of autobiographical memory were discussed. In Part 2, the cognitive-perceptual method will be used to interpret several early memories and a slightly abridged Early Memories Procedure (EMP).  相似文献

177 respondents attending a midwestern state university reported greater alienation from the wider society when they held more positive attitudes than negative ones toward women and homosexuals. Alienation and attitudes toward African-Americans, women, and homosexuals were not influenced by gender or religiosity.  相似文献

A capacity theory of comprehension: individual differences in working memory.   总被引:77,自引:0,他引:77  
A theory of the way working memory capacity constrains comprehension is proposed. The theory proposes that both processing and storage are mediated by activation and that the total amount of activation available in working memory varies among individuals. Individual differences in working memory capacity for language can account for qualitative and quantitative differences among college-age adults in several aspects of language comprehension. One aspect is syntactic modularity: The larger capacity of some individuals permits interaction among syntactic and pragmatic information, so that their syntactic processes are not informationally encapsulated. Another aspect is syntactic ambiguity: The larger capacity of some individuals permits them to maintain multiple interpretations. The theory is instantiated as a production system model in which the amount of activation available to the model affects how it adapts to the transient computational and storage demands that occur in comprehension.  相似文献
