This study examined the prospective relations among family history density of alcoholism (FHD), adolescent family harmony, and young adults' alcohol and drug dependence. Family harmony was rated by mothers and fathers in adolescence, and young adults' substance dependence diagnoses were obtained through structured interviews. Higher FHD predicted lower adolescent family harmony, which in turn increased young adults' odds of being diagnosed with drug dependence (with and without alcohol dependence) compared to no diagnoses or to alcohol dependence only. Family harmony also interacted with FHD such that the protective effect of family harmony on young adults' drug dependence with or without alcohol dependence decreased as FHD rose, and was nonsignificant at high levels of FHD. The findings suggest the importance of distinguishing among alcohol and drug dependence disorders and examining their differential etiological pathways, and also suggest that the protective effects of harmonious family environments on substance dependence may be limited at high levels of FHD. 相似文献

Same/different abstract-concept learning by pigeons 总被引:1,自引:0,他引:1
Eight pigeons were trained and tested in a simultaneous same/different task. After pecking an upper picture, they pecked a lower picture to indicate same or a white rectangle to indicate different. Increases in the training set size from 8 to 1,024 items produced improved transfer from 51.3% to 84.6%. This is the first evidence that pigeons can perform a two-item same/different task as accurately with novel items as training items and both above 80% correct. Fixed-set control groups ruled out training time or transfer testing as producing the high level of abstract-concept learning. Comparisons with similar experiments with rhesus and capuchin monkeys showed that the ability to learn the same/different abstract concept was similar but that pigeons require more training exemplars. 相似文献

Yes we can! is a community-building initiative funded by the W. K. Kellogg Foundation that aims to improve educational and economic outcomes in Battle Creek, Michigan by mobilizing low-income communities and resident leaders and building their capacity to influence the decisions and policies that impact their lives. This paper describes the strategies pursued during the first phase of this initiative to foster resident mobilization by building small wins within the neighborhood. Primarily through a neighborhood-based mini-grant program and staff supports to encourage collective action, Yes we can! has started to increase levels of resident mobilization within the seven economically distressed neighborhoods that initially partnered with the W. K. Kellogg Foundation on this effort. The specific programming components and how they were implemented as well as the initial successes experienced are described. Lessons learned are discussed. 相似文献

We replicated and extended treatment procedures described by Lennox, Miltenberger, and Donnelly (1987) designed to reduce rapid eating. The participant was a 17-year-old girl with developmental disabilities who engaged in dangerously high rates of food ingestion. The procedure involved an adjusting differential-reinforcement-of-low-rate-responding (DRL) schedule, response blocking, and prompts. We evaluated a continuation of the treatment despite initial negative side effects that were similar to those reported by Lennox et al. Results showed that the treatment package was effective and negative side effects eventually decreased. 相似文献

To investigate the role that "nonlogical" cues might play in transitive inference, 6- and 7-year-olds were given a three-term transitive task in which perceptual cues to differential absolute size were either present or absent. Relationships between the taught premises and the relational information that was physically present were manipulated using four basic conditions: "congruent," "inverse," "pretended," or "persuaded." Both age groups showed identical overall premise memory, but the younger group tended to reason more on the basis of the perceptual information rather than on the successfully encoded premise information. Contrasts between the various conditions showed that categorical effects can be circumvented in three-term problems with appropriate controls, that there may be qualitative as well as quantitative differences in transitive inference with age, and that transitive inference is not based solely on memory. The findings also indicate that, although 7-year-olds are competent in "logic-based" transitive inference, they experience great difficulty on tasks involving pretend information. 相似文献

The nonconsciousness of self-consciousness 总被引:2,自引:0,他引:2
Hull JG Slone LB Meteyer KB Matthews AR 《Journal of personality and social psychology》2002,83(2):406-424
Five studies demonstrated that private self-consciousness is associated with nonconscious, automatic behaviors. In 2 studies, high but not low self-conscious individuals walked more slowly following exposure to an implicit elderly prime. In a 3rd study, high but not low self-conscious individuals showed improved performance following exposure to a subliminal success prime relative to a subliminal failure prime. In a 4th study, subliminal exposure to an angry prime was shown to increase blood pressure relative to a relax prime. In a final study, the latter effect was shown to be true only for high self-conscious individuals and only for subliminal presentations. Results are discussed in terms of their implications for understanding a variety of effects associated with self-consciousness and self-awareness. 相似文献

The personal/group discrimination discrepancy involves disadvantaged group members rating discrimination directed at their group considerably higher than ratings of discrimination aimed at themselves personally as members of that group. This robust phenomenon has been found in samples of women, African Americans, and aboriginal people. In the present study, the authors used a sample of Inuit from a remote Arctic community to confirm the perceived discrepancy. However, ratings for perceived group discrimination were surprisingly low. The authors argue that geographical isolation may have led Inuit to be unaware of the impact of discrimination on their lives. In support of this argument, findings showed that group discrimination ratings were higher for Inuit who did have contact with mainstream Canadian culture. Implications for the traditional contact hypothesis are discussed. 相似文献

We examined the contribution of semantics to morphological facilitation in the visual lexical decision task at two stimulus onset asynchronies (SOAs) with Serbian materials. Primes appeared in Roman or Cyrillic characters. Targets always were printed in Roman. When primes were presented at an SOA of 250 msec, decision latencies to verbal targets (e.g., VOLIM) showed greatest facilitation after inflectionally (e.g., VOLE) related primes, significantly less after semantically transparent derived primes (e.g., ZAVOLE), and less again after semantically opaque derived primes (e.g., PREVOLE). Latencies after semantically transparent and opaque derived target words did not differ at an SOA of 48 msec. Both were slower than after inflectionally related primes. Stated generally, effects of semantic transparency among derivationally related verb forms were evident at long SOAs, but not at short ones. Under alphabet-alternating conditions, magnitudes of facilitation were greater overall, but the pattern was similar. The outcome suggests that restricted processing time for the prime limits the contribution of semantics to morphological processing and calls into question accounts that posit a task-invariant semantic criterion for morphological decomposition within the lexicon. 相似文献

A rhesus monkey was tested in an auditory list memory task with blocked and mixed retention delays. Each list of four natural or environmental sounds (from a center speaker) was followed by a retention delay (0, 1, 2, 10, 20, or 30 sec) and then by a recognition test (from two side speakers). The monkey had been tested for 12 years in tasks with blocked delays. An earlier (4 years prior) blocked-delay test was repeated, with virtually identical results. The results from the mixed-delay test were likewise similar. Thus, the peculiarities of blocked-delay testing, such as delay predictability or differences in list spacing, apparently do not alter this monkey's memory for auditory lists. It is concluded from this and other evidence that the monkey's serial position functions reflect mnemonic processes that change with changes in retention delay and are not artifacts of the blocked-delay procedure. The nature of the monkey's auditory memory is discussed. 相似文献

Ten-year-old children performed a fragment completion task. Target fragments (e.g., T_ _N) were preceded by four types of study conditions. The identity condition consisted of the target (TURN). Themorphological condition included a related form (TURNED). The orthographic condition consisted of morphologically unrelated words (e.g., TURNIP). Finally, no similar word was presented in the study phase of the no-prime condition. Morphological relatives included orthographically transparent (TURNED-TURN) and orthographically opaque (RIDDEN-RIDE) forms. The results indicated that performance of child readers on the fragment completion task was sensitive to morphological relationships. Completion rates following opaque, as well as transparent, morphological relatives were significantly greater than those following orthographically similar forms. In sum, the fragment completion task provides a viable new tool for examining morphological processing in children and for differentiating morphological effects from effects of similar form. 相似文献
