Self-report measures of grief, depression, and general psychopathology were studied in widows and widowers over a 2.5-year period following death of their partner. A comparison sample of men and women was also followed for the same period. Differences in severity of depression and psychopathology previously reported at 2 months postloss (Gallagher, Breckenridge, Thompson, & Peterson, 1983) diminished to nonsignificant levels at 12 and 30 months. However, significant differences between bereaved and comparison subjects on measures of grief were still apparent 30 months after spousal loss. A main effect of gender for depression and psychopathology (but not for grief) was found at 2 and 12 months: Women reported more distress than men regardless of bereavement status. Results indicate that the experience of grief persists for at least 30 months in both older men and women who have lost their spouse.  相似文献

Older and young adults' letter detection and lexical decision performance were examined as word frequency varied to determine whether there were age differences in word recognition. Allen and Madden (1989) found that older adults' pattern of reaction time (RT) across word frequency categories was different from young adults' pattern for a letter detection task. In this study, for both letter detection and lexical decision tasks, older adults exhibited a monotonically decreasing RT function as word frequency increased. However, young adults exhibited a nonmonotonic RT function across word frequency for the letter detection task but a monotonically decreasing RT function as word frequency increased for the lexical decision task. An expanded parallel input serial analysis model of word processing was hypothesized.  相似文献

Each year, large amounts of human energy, mind, time, as well as raw materials and capital are converted into goods/services available for purchase. Developing basic science to support a task so significant for the quality of individual lives has fallen between the cracks of existing disciplines. Missing the true meaning of division of labor, existing conceptualizations focus on the producer's side of the transaction, neglecting the user's. To begin to remedy this imbalance, the present paper discusses the implications for the quality of individual lives of the marketer's task at micro and macro levels.  相似文献

When was the last time you saw a job application with no spelling or grammatical errors? Basic skill deficiencies among people at all levels of business are forcing companies to develop innovative ways of compensating for and correcting the problem. What follows is a summary of literacy training strategies and suggestions for implementation.  相似文献

In spite of numerous demonstrations that America's youth can be effectively educated with behavior analytic teaching techniques, few of the country's children are benefiting from the technology. In addition scholarly reviews of effective teaching strategies have often omitted reference to behavior analysis. One way to look at this problem is as a two-step operation. First, it is necessary to determine procedures that work; second it is necessary to devise strategies for effective dissemination. The present issue of JOBE (Vol. 1, No. 3, Sept. 1991) contains the recommendations of six outstanding behavioral educators as to how to deal with the dissemination problem. The initial article by Pumroy and McIntire describes the activities of an organization which trains school psychologists and teachers to use behavioral procedures and advocates for the techniques with a number of audiences. Next, Engelmann suggests that the public have more control over school activities and that legal action be taken against irresponsible administrative decisions. Hall advocates for less labor-intensive procedures and the sale of curricular materials based on behavioral principles. Binder proposes that dissemination of the technology become a private endeavor that responds to consumer needs. Rosenfield describes a collaborative model of consultation that increases treatment adherence. Finally, Albers and Greer describe research that isolates a key teacher behavior that results in greater academic proficiency.  相似文献

Adult subjects were presented with two auditory stimuli per trial, and their task was to decide which of the two was longer in duration. An adaptive psychophysical procedure was used. In Experiments 1, 2, and 4, the base duration was 50 msec, whereas in Experiment 3, the base duration was 1 sec. In Experiments 1, 2, and 4, it was found that filled intervals (continuous tones) were discriminated more accurately than empty intervals (with onset and offset marked by clicks). It was concluded that this difference was perceptual rather than cognitive in nature, since performance on filled and empty intervals was not affected by increasing cognitive load in a dual-task procedure (Experiment 2) but was affected by backward masking (Experiment 4). In contrast, the results of Experiment 3 showed that duration discrimination of filled auditory intervals of longer duration was cognitively influenced, since performance was impaired by increasing cognitive load. Implications for notions of perceptual processing and timing mechanisms tanderlying differences in duration discrimination with filled and empty intervals are discussed.  相似文献
