In three experiments, we examined why pictures are remembered better than words on explicit memory tests like recall and recognition, whereas words produce more priming than pictures on some implicit tests, such as word-fragment and word-stem completion (e.g., completing -l-ph-nt or ele----- as elephant). One possibility is that pictures are always more accessible than words if subjects are given explicit retrieval instructions. An alternative possibility is that the properties of the retrieval cues themselves constrain the retrieval processes engaged; word fragments might induce data-driven (perceptually based) retrieval, which favors words regardless of the retrieval instructions. Experiment 1 demonstrated that words were remembered better than pictures on both the word-fragment and word-stem completion tasks under both implicit and explicit retrieval conditions. In Experiment 2, pictures were recalled better than words with semantically related extralist cues. In Experiment 3, when semantic cues were combined with word fragments, pictures and words were recalled equally well under explicit retrieval conditions, but words were superior to pictures under implicit instructions. Thus, the inherently data-limited properties of fragmented words limit their use in accessing conceptual codes. Overall, the results indicate that retrieval operations are largely determined by properties of the retrieval cues under both implicit and explicit retrieval conditions. 相似文献

Trial-and-error and errorless training procedures were used to train two killer whales on a simple visual discrimination problem. Both whales demonstrated difficulties in solving the problem under trial-and-error training. The relative effectiveness of the two training procedures is evaluated. 相似文献

Newborn screening has existed as a state-based public health service since the early 1960s. Every state and most territorial jurisdictions have comprehensive newborn screening programs in place, but in the United States a national newborn screening policy does not exist. This results in different administrative infrastructures, screening requirements, laboratory and follow-up services, medical management approaches, and related activities across the country. Federal initiatives and support have contributed to limited evaluations of various aspects of individual newborn screening programs at the national level, but funding is an issue. The national evaluation strategies have taken various forms, all with the intent of improving the screening system through review of actions taken and suggestions for future improvements. While participation in the national evaluation effort for newborn screening laboratory practices includes all US programs, and this has aided in improving quality and harmonizing protocols, other national evaluation activities have been only moderately successful. National data reporting of quality indicators for various program elements must be comprehensive and timely, and the elements must be universally accepted in order to meet the evaluation and improvement needs of the national newborn screening system. A comprehensive real time national evaluation activity will likely require additional resources and enforcement incentives. Limited federal actions through grant incentives and selected reporting requirements provide a possible means of stimulating programs to participate in national harmonization efforts. 相似文献

This article provides an update on two significant contributions to the assessment of attachment in adolescents and adults. Two measures of adult attachment, both based on modifications of Hazan and Shaver's (1987) model of adult attachment, are reviewed. The conceptual bases for the development of each measure are discussed, current research involving each measure is presented, and implications of attachment assessment for counseling research and practice are offered. 相似文献

Purpose: Postpartum mood disorders (PMDs), the distressing mental and emotional symptoms experienced by women after childbirth, are just now receiving the attention they warrant. Given the serious and sometimes life‐threatening nature of PMDs, we used a qualitative research design to examine more closely the nature of symptoms experienced and the effective strategies women used to cope with PMD. Participants: The respondents were 252 members of PMD and breast‐feeding (La Leche League) support groups throughout the United States. Method: Participants responded anonymously to open‐ended questions in an online survey. The data were reviewed by the research team to determine common themes and prevailing issues. Results: Participants reported myriad different symptoms and used a host of various strategies to alleviate problematic thoughts, feelings, and behaviours following childbirth. Postpartum symptoms affected participants’ plans to have future children. For some women, symptoms became more intense during subsequent births. Despite the problematic nature of PMD, more than half of the participants reported receiving little or no information from healthcare providers about PMDs. Implications for counsellors and other healthcare providers are discussed in detail. 相似文献

OBJECTIVE: Health communication can help reduce the cancer burden by increasing processing of information about health interventions. Negative affect is associated with information processing and may be a barrier to successful health communication. DESIGN AND MAIN OUTCOME MEASURES: We examined associations between negative affect and information processing at the population level. Symptoms of depression (6 items) and cancer worry (1 item) operationalized negative affect; attention to health information (5 items) and cancer information-seeking experiences (6 items) operationalized information processing. RESULTS: Higher cancer worry was associated with more attention to health information (p<.01) and worse cancer information-seeking experiences (p<.05). More symptoms of depression were associated with worse information-seeking experiences (p<.01), but not with attention. CONCLUSIONS: We found population-level evidence that increased cancer worry is associated with more attention to health information, and increased cancer worry and symptoms of depression are associated with worse cancer information-seeking experiences. Results suggest that affect plays a role in health information processing, and decreasing negative affect associated with cancer communication may improve experiences seeking cancer information. 相似文献
