Repetitions that are distributed over time benefit long‐term retention more than when massed. Recent research has suggested that the advantage of spacing may extend to induction learning‐‐learners were better able to identify the artists of previously unseen paintings when, during training, artists' paintings were spaced (paintings by different artists were interleaved) rather than massed (a given artist's paintings were blocked and presented consecutively). Increasing temporal spacing between paintings while maintaining a presentation sequence that was blocked by artist produced test performance no better than massed presentation (both worse than interleaved presentation) (Experiment 1). Displaying paintings by different artists simultaneously produced test performance as good as interleaved presentation and better than massed presentation (Experiment 2). Our findings argue that spacing benefits perceptual induction learning not because of increased temporal spacing per se but rather because interleaving paintings by different artists enhances discriminative contrast between the artists' styles.

孔子与《易》是有密切关系的,抛开《史记》和帛书的记载不言,仅就《论语》中两条最直接的材料来看确实如此。"加我数年……"当为孔子五十之前所说。五十之前,孔子也曾学《易》,而孔子认为知天命之年尤需学《易》。"不占而已"表明孔子解《易》以德,判定吉凶不需要占筮,而是取决于人的德性。孔子以"生生之德性"解《易》,以"道德必然性"解"天命",通过揭去《周易》的神秘外衣,发掘并发展其天人之学,将隐微难言的性与天道托诸于显著的人道德性,发展出天人合一的德性学说。  相似文献

There is professional consensus that teleanalysis, the practice of psychoanalysis conducted remotely using the telephone and the Internet, is increasing in response to more mobility in the population. But there is controversy as to whether the use of technology leads to a dilution of analysis or to adaptive innovation that is clinically effective and true to the tenets of psychoanalysis. The author reviews the psychoanalytic literature and shows the development of analytic thinking about this technology-assisted practice of psychoanalysis. She summarizes analysts' perceptions and experiences of the advantages and disadvantages, and considers the indications and contra-indications. She focuses on the clinical concerns that arise in terms of the frame, resistance, and the development of analytic process through the unconscious communication of internal objects, unconscious fantasy, transference and countertransference. She gives vignettes from the analysis of a man with trauma-related depression to address the concerns raised and to support her argument that analysis using the telephone and the Internet is a viable, clinically effective alternative to traditional analysis where necessary.  相似文献

Abstract

The authors examined the effectiveness of conflict resolution and peer mediation training among California high school students. The authors randomly assigned 2 of 4 classes to receive 5 weeks of conflict resolution and peer mediation training integrated into the required social studies curriculum. The remaining 2 classes studied the same social studies curriculum for an identical amount of time (105 min every other day) without conflict resolution and peer mediation training. The authors investigated 2 issues. The 1st was the effectiveness of the conflict resolution and peer mediation training. The trained students, compared with the untrained students, learned the integrative negotiation and peer mediation procedures better, applied the procedures more completely, chose an integrative over a distributive approach to negotiation, and developed more positive attitudes toward conflict. The 2nd issue was the impact of the training program on academic achievement. Integrating conflict resolution and peer mediation training into an academic course promoted higher achievement, greater long-term retention of the academic learning, and greater transfer of academic learning in social studies to language arts.  相似文献

In a typical transposition task, an animal is presented with a single pair of stimuli (for example, S3+ S4−, where plus and minus denote reward and nonreward and digits denote stimulus location on a sensory dimension such as size). Subsequently, an animal is presented with a testing pair that contains a previously reinforced or nonreinforced stimulus and a novel stimulus (for example, S2–S3 and S4–S5). Does the choice of a novel S2 instead of previously reinforced S3 in a testing pair S2–S3 indicate that the animal has learned a relation (i.e., “select smaller”)? This review of empirical evidence and theoretical accounts shows that an organism''s behavior in a transposition task is undoubtedly influenced by prior reinforcement history of the training stimuli (Spence, 1937). However, it is also affected by two other factors that are relational in nature—a similarity of two testing stimuli to each other and an overall similarity of the testing pair as a whole to the training pair as a whole. The influence of the two latter factors is especially evident in studies that use multiple pairs of training stimuli and a wide range of testing pairs comprising nonadjacent stimuli (Lazareva, Miner, Young, & Wasserman, 2008; Lazareva, Wasserman, & Young, 2005). In sum, the evidence suggests that both prior reinforcement history and relational information affect an animal''s behavior in a typical transposition task.  相似文献

Larsson Sundqvist, M., Todorov, I., Kubik, V. & Jönsson, F.U. (2012) Study for now, but judge for later: Delayed judgments of learning promote long‐term retention. Scandinavian Journal of Psychology 53, 450–454. Delayed judgments of learning (JOL) are assumed to be based on covert retrieval attempts. A common finding is that testing memory during learning improves later retention (i.e., the testing effect), and even more so than an equivalent amount of study, but only after a longer retention interval. To test the assertion that also delayed JOLs improve memory, the participants either studied Swahili‐Swedish word pairs four times, or they both studied (two times) and performed delayed JOLs (two times) alternately. Final cued recall test were given after either five minutes or one week. Results showed a reliable learning‐group by retention‐interval interaction, with less forgetting in the group that alternated between studying and making JOLs. The results are discussed in relation to the self‐fulfilling prophecy account of Spellman and Bjork (1992) , and in terms of study advice, the results further underscore the importance of delaying JOLs when studying and evaluating one’s ongoing learning.  相似文献

What mechanism implements the mutual exclusivity bias to map novel labels to objects without names? Prominent theoretical accounts of mutual exclusivity (e.g., Markman, 1989, 1990 ) propose that infants are guided by their knowledge of object names. However, the mutual exclusivity constraint could be implemented via monitoring of object novelty (see Merriman, Marazita, & Jarvis, 1995 ). We sought to discriminate between these contrasting explanations across two preferential looking experiments with 22‐month‐olds. In Experiment 1, infants viewed three objects: one name‐known, two name‐unknown. Of the two name‐unknown objects, one was novel, and the other had been previously familiarized. The infants responded to hearing a novel label by increasing attention only to the novel, name‐unknown object. In a second experiment in which the name‐known object was absent, a novel label increased infants’ attention to a novel object beyond baseline preference for novelty. The experiments provide clear evidence for a novelty‐based mechanism. However, differences in the time course of disambiguation across experiments suggest that novelty processing may be influenced by contextual factors.  相似文献

Truly flower-naïve bumblebees, with no prior rewarded experience for visits on any visual patterns outside the colony, were tested for their choice of bilaterally symmetric over asymmetric patterns in a radial-arm maze. No preference for symmetry was found. Prior training with rewarded black and white disks did, however, lead to a significant preference for symmetry. The preference was not specific to symmetry along the vertical axis: a preference for horizontal symmetry was found as well. The results challenge the notion that a preference for bilateral symmetry is unlearned. The preference for symmetry was the product of non-differential conditioning.  相似文献

The interaction between redundant geometric and featural cues in open field search tasks has been examined widely with results that are not always consistent. Cheng (1986) found evidence that when searching for food in rectangular environments, rats used the geometrical characteristics of the environment rather than local featural cues, suggesting that geometry had overshadowed featural cues. More recently, Graham et al. (2006) and Pearce et al. (2006) found that wall color facilitated (potentiated) learning about the shape of the environment by rats in a kite-shaped water maze. The first experiment in the present research replicated the paradigm used by Graham et al. and Pearce et al. using rats in a foraging situation, but with conditions similar, and found the same results, potentiation of shape by color. Experiments 2 and 3 revealed overshadowing instead of potentiation of shape by wall color under the same conditions except that the wall colors of the test environment were not the same as those used during training. The results are consistent with an analysis of the role of associations formed between wall color and geometry in such situations (Rhodes et al., 2009) and extend our understanding of how featural and spatial cues interact.  相似文献
