Three experiments are reported in which the strategy usage for a compass point directions task was investigated. For this task, people may use either an efficient cancellation strategy or an inefficient spatial strategy (see Roberts, Gilmore, & Wood, 1997). Experiment 1, together with Experiment 2, showed that users of cancellation are unlikely to have explicit prior knowledge of this strategy; instead they discover it as a result of experience with the task. Experiment 1 also showed that strategy selection is unlikely to be based on stylistic preferences, and that reducing the cognitive demands of the task does not increase the discovery of cancellation. Experiment 3 showed that evaluation of strategy validity is also of importance: Unsuccessful evaluation may prevent the selection of a newly discovered strategy, even if it is the more efficient method. 相似文献

The effect of sentence priming on picture naming was investigated across the lifespan, from age 3 to 87 years. Names that are normally acquired before 3 years of age were presented in auditory contexts that were semantically congruent, incongruent, or neutral in relation to each picture and its name. Sentential priming was present at all age levels. Facilitation (neutral vs. congruent) was significantly by 4 years of age and did not vary significantly with age. Interference (incongruent vs. neutral) was significant at all age levels, but changed nonmonotonically with age (largest in the youngest children, stable from young adulthood through age 70, with a small increase in the oldest participants). We conclude that picture naming is a useful tool for the investigation of sentential priming effects across the lifespan and that it can reveal potentially interesting developmental changes in the effects of sentential context on word retrieval. 相似文献

This study explored the roles of referent power (i.e., influence based on sense of identification) and expert power (i.e., influence based on knowledge and expertise) in Schizophrenics Anonymous (SA), a mutual-help group for persons experiencing a schizophrenia-related illness. The study describes SA participants' experience of referent and expert power with SA members, SA leaders, and with mental health professionals. It also examines whether or not referent and expert power ascribed to fellow SA participants predicts the perceived helpfulness of the group. One hundred fifty-six SA participants were surveyed. Participants reported experiencing higher levels of referent power with fellow SA members and leaders than with mental health professionals. They reported higher levels of expert power for mental health professionals and SA leaders than for SA members. The respondents' ratings of their SA group's helpfulness was significantly correlated with ratings of referent and expert power. Although expert power was the best independent predictor of helpfulness, a significant interaction between referent and expert power indicated that when members reported high referent power, expert power was not related to helpfulness. These results are interpreted to suggest that there are multiple forms of social influence at work in mutual help. 相似文献

Confidence and accuracy, while often considered to tap the same memory representation, are often found to be only weakly correlated
(e.g., Bothwell, Deffenbacher, & Brigham, 1987; Deffenbacher, 1980). There are at least two possible (nonexclusive) reasons
for this weak relation. First, it may be simply due to noise of one sort or another; that is, it may come about because of
both within- and between-subjects statistical variations that are partially uncorrelated for confidence measures on the one
hand and accuracy measures on the other. Second, confidence and accuracy may be uncorrelated because they are based, at least
in part, on different memory representations that are affected in different ways by different independent variables. We propose
a general theory that is designed to encompass both of these possibilities and, within the context of this theory, we evaluate
effects of four variables—degree of rehearsal, study duration, study luminance, and test luminance—in three face recognition
experiments. In conjunction with our theory, the results allow us to begin to identify the circumstances under which confidence
and accuracy are based on the same versus different sources of information in memory. The results demonstrate the conditions
under which subjects are quite poor at monitoring their memory performance, and are used to extend cue utilization theories
to the domain of face recognition. 相似文献

The Role of Families and Care Givers as Risk and Protective Factors in Preventing Youth Violence 总被引:3,自引:0,他引:3
This paper reviews research which discusses the risk and protective functions that families and other caregivers provide in influencing the development of aggressive behavior in youth. Currently, there is an emphasis on providing violence prevention programs in the school environment, typically with little parental or caregiver involvement. By enhancing the role of families and caregivers in youth violence prevention programs, we assert that an unique opportunity exists to both address specific risk factors for violence while enhancing the protective features of the family. Relatedly, the risk literature on youth violence indicates that the most influential risk factors (i.e., the family, community, and peers) have their principle impact on youth aggression outside the school. We suggest a shift in the focus of violence prevention programming that is more inclusive of families as both a risk and protective agent. In support of this position, relevant theory and reviews of exemplary family-involved programs are offered. Challenges to involving youth caregivers are identified and recommendations for overcoming those challenges suggested. Last, recommendations for future research and public policy in the prevention of youth violence are offered. 相似文献

Two name-learning techniques were compared: expanding rehearsal and name-face imagery. Participants studied name-face associations and were given a cued recall test in which they were presented with a face and were to recall the name. They were presented with either an expanding rehearsal schedule (expanding condition), a distinctive facial feature coupled with a word phonologically similar to the last name and an interactive image linking the name and facial feature (name-face imagery condition), or a no memory (control) strategy. The expanding rehearsal schedule led to superior name learning relative to the name-face imagery and control conditions after a 15-min (Experiment 1) or 48-hr (Experiment 2) retention interval. In Experiment 3, the retrieval practice explanation was tested but not supported; we argue that an encoding variability interpretation is consistent with the overall pattern of results. Applied implications are also discussed. 相似文献
