This phenomenological study suggests that generativity, long conceptualized as a stage of individual psychosocial development, is a collaborative experience in the developmental trajectory of some marriages and long‐term partnerships. This new knowledge was developed through exploring the lived experience of 10 middle‐aged and older couples who participated in this research. Termed “generative partnership,” this collaborative experience includes 3 facets: embracing generative identity, contributing talents and resources, and passing it on. Findings suggest that generative partnerships enhance satisfaction and vitality in relationships at midlife and beyond as couples encounter the opportunities and challenges of growing old together. 相似文献

It is common practice in research on the treatment of problem behavior to compare levels of targeted behaviors during treatment to levels when treatment is not in place. Some researchers use data collected as part of a multielement functional analysis as the initial baseline, whereas others collect new baseline data following completion of the functional analysis. We evaluated whether the source of baseline data influences the reliability and efficiency of decision-making. Results suggest that similar decisions are made in regard to treatment efficacy using the different sources of baseline data, but using data from a multielement functional analysis as baseline may save time. Interrater agreement was adequate, but lower for some graphs than has been observed in past studies. Several potential explanations for this discrepancy are discussed. 相似文献

Seven healthy subjects underwent functional magnetic resonance imaging (fMRI) of the brain while performing an inspection time task. Employing a block-type design, the task had three difficulty levels: a control condition, an easy (200 ms stimulus duration), and a more difficult (40 ms) discrimination. Based on group results, there were widespread significant areas of difference in brain activation and deactivation when pairwise comparisons were conducted among the three task conditions. When the difficult condition was compared with the easy condition, there was relative activation in areas of the following brain regions: cingulate gyrus and some frontal and parietal lobe areas. Areas within the following regions showed relative deactivation (greater blood oxygenation level-dependent, BOLD, signal in the easy condition): frontal, temporal, and parietal lobe. There were overlaps between these areas and those found to be active while performing higher cognitive tasks in other functional brain imaging studies. These pilot data encourage future studies of the functional anatomy of inspection time and its relevance to psychometric intelligence. 相似文献

The notion of absolute independence, considered in this paper has a clear algebraic meaning and is a strengthening of the usual notion of logical independence. We prove that any consistent and countable set in classical prepositional logic has an absolutely independent axiornatization. 相似文献

To investigate the hypothesis that sulpiride potentiates stereotyped locomotion at an intermediate dose of amphetamine, rats
were assigned to one of four treatment groups (n=7 per group): vehicle + saline; 20 mg/kg sulpiride + saline; vehicle + 3.5mg/kg
amphetamine; 20 mg/kg sulpiride + 3.5 mg/kg amphetamine. An automated tracking system was used to record distance moved and
sequences of movements between quadrants in a circular open-field. The results showed that amphetamine increased horizontal
distance moved, and increased the number and proportion of thigmotaxic trips around the perimeter of the apparatus. Sulpiride
reduced amphetamine-induced hyperactivity and the number of perimeter trips, but had no effect on the proportion and maximum
run length of perimeter trips. Thus sulpiride reduces the hyperactivity produced by an intermediate dose of amphetamine, but
does not appear to affect the stereotyped nature of locomotion under the drug. 相似文献

This study examined determinants of substance use derived from the theory of planned behavior as influenced by acculturation. Latino adolescents (n= 448) completed measures of attitudes, subjective norms, perceived behavioral control, intentions toward substance use, and 2 acculturation components. The degree to which Latino adolescents were exposed to as well as use Spanish was unrelated to determinants of future substance use, whereas the degree to which they interact with non-Latino peers exerted a protective effect regarding future substance use. However, both acculturation components influenced the extent social influence determinants predicted future substance use. Intervention strategies may need to consider acculturation in order to effectively direct resources toward those psychosocial determinants of substance use of greatest relevance to Latino populations. 相似文献

In a study examining inferences made about couples based on their choice whether or not to have children, college undergraduates projected 1-year and 25-year life situations for a hypothetical couple who either (1) neither had nor wished to have children, (2) were presented without any reference to children, or (3) already had two children. This manipulation notwithstanding, most couples were projected as becoming parents. Female subjects saw having children as enhancing the quality of life of both partners, while males took the opposite view. 相似文献

Stereoacuity and resolution acuity were measured (1)through apertures set at various distances from O and (2) through plus lenses producing an accommodative error for the target equal to that produced by the presence of the apertures. Stereoacuity was degraded by the apertures but not by the lenses, whereas resolution acuity was degraded by the lenses but not by the apertures. Although stereoacuity progressively declined with decreasing target distance, it did not change significantly if accommodation remained constant. The decline of stereoacmty in the water ts attributed to increased accommodation resulting from different sources and to a “Ganzfeld” effect of the typical underwater scene. 相似文献
