The effect of repeated testing on delayed relearning of paired associates was investigated. Participants learned two lists of Lithuanian-Dutch word pairs until reaching the criterion of one correct recall from long-term memory. In one condition, items subsequently received three post-retrieval study trials and in the other condition items received three post-retrieval test trials. Participants returned one week later for delayed recall and relearning. Post-retrieval test trials resulted in better delayed recall performance than post-retrieval study trials. Moreover, we found that the items that were repeatedly studied or tested one week prior to relearning were relearned faster than a new set of similar (not previously presented) items. Most importantly, items were relearned faster when they had previously been learned under conditions of post-retrieval testing than items learned under conditions of post-retrieval study. Taken together, the results indicate that the benefits of repeated testing are not just limited to conscious recall on a delayed test. Repeated testing during initial learning is also a very effective strategy to enhance delayed relearning. 相似文献

Twenty-one normally developing 3-year-old children were tested on two approximant consonant contrasts, rake-lake and wake-rake, and a control contrast, wake-bake. Perception was assessed in a two-choice picture identification paradigm; stimuli were (1) natural and computer synthesized “clear cases” of the minimal pairs, and (2) synthetic stimulus series which interpolated on acoustic dimensions that differentiate the minimal pairs. As a group, the children showed very accurate perception of the minimal pairs. Performance on the synthetic series yielded consistent identification of the endpoint stimuli and monotonic functions with abrupt crossovers at the phoneme boundary. Children who did not yet articulate /r/ and /l/ appropriately showed somewhat less consistent perception than children who produced all phonemes correctly. 相似文献

To acquire representations of printed words, children must attend to the written form of a word and link this form with the word's pronunciation. When words are read in context, they may be read with less attention to these features, and this can lead to poorer word form retention. Two experiments with young children (ages 5-8 years) confirmed this hypothesis. In our experiments, children attempted to read words they could not previously read, during a self-teaching period, either in context or in isolation. Later they were tested on how well they learned the words as a function of self-teaching condition (isolation or context). Consistent with previous research, children read more words accurately in context than in isolation during self-teaching; however, children had better retention for words learned in isolation. Furthermore, this benefit from learning in isolation was larger for less skilled readers. This effect of poorer word retention when words are learned in context is paradoxical because context has been shown to facilitate word identification. We discuss factors that may influence this effect of context, especially the role of children's skill level and the demands of learning new word representations at the beginning of reading instruction. 相似文献

Preschool children were trained on a color relevant oddity problem by one of three methods: increased salience of the oddity relationship, instruction on the solution rule, or a combination of increased salience and rule instruction. The youngest Ss solved the training problem when the solution rule was provided but not under the salience procedure. The two older groups solved in all conditions and errors decreased with age. The generality of the solution was determined by performance on a form relevant transfer task. The youngest Ss made fewer errors on the transfer problem following rule instruction training than following training in the combined procedure. The intermediate age group made fewer errors when the transfer task was administered one week after training than one minute after training. The transfer problem was easily solved by the oldest Ss and performance was independent of training procedure and amount of delay. These results were interpreted as reflecting developmental differences in relational concept learning. 相似文献

Three experiments are reported in which subjects chose from an array the response alternative that most resembled a nonsense stimulus trigram or quingram. Subjects could respond on the basis of individual letter positions or overall word shape. However, word shape was not manipulated independently of the individual letters that comprise the word as has been the case in previous studies. Kindergarten children and first graders who were poor readers showed a more varied pattern of responses than first graders who were good readers. With simple stimuli (trigrams), beginning and skilled readers chose alternatives on the basis of overall shape and the initial letter. With more complex stimuli (quingrams), the skilled readers continued choosing on the basis of word shape and initial letters, but beginning readers only chose on the basis of the first letter. 相似文献

Aiming for career success: The role of learning goal orientation in mentoring relationships 总被引:2,自引:0,他引:2
Learning goal orientation of mentors and protégés was investigated as it relates to protégés’ mentoring functions received and outcomes (i.e., managerial career aspirations and career satisfaction). Data from 217 mentor-protégé dyads comprised of working professionals from a variety of industries were analyzed using multivariate analysis of covariance. Results indicated that protégés who possessed high levels of learning goal orientation similar to their mentor were associated with the highest levels of psychosocial support. These protégés also reported higher levels of career development, idealized influence, enacted managerial aspirations, desired managerial aspirations, and career satisfaction when compared to mentor-protégé dyads who possessed low levels of learning goal orientation or dyads with dissimilar levels of learning goal orientation. Implications for practice and future research are discussed. 相似文献

In an interference-between-cues design (IbC), the expression of a learned Cue A–Outcome 1 association has been shown to be impaired if another cue, B, is separately paired with the same outcome in a second learning phase. The present study examined whether IbC could be caused by associative mechanisms independent of causal reasoning processes. This was achieved by testing participants in two different learning situations. In the Causal Scenario condition, participants learned in a diagnostic situation in which a common cause (Outcome 1) caused two disjoint effects, namely Cues A and B. In the Non-Causal Scenario condition, the same IbC design and stimulus conditions were used. However, instructions provided no causal frame to make sense of how cues and outcomes were related. IbC was only found in the Causal Scenario condition. This result is consistent with Causal Reasoning Models of causal learning and raises important difficulties for associative explanations of IbC. 相似文献

We have reported that the expression of conditioned place avoidance (CPA) in the golden hamster is regulated in a circadian pattern such that the preference is exhibited strongly at the circadian time of prior training but not at other circadian times [Cain, S. W., Chou, T., & Ralph, M. R. (2004a). Circadian modulation of performance on an aversion-based place learning task in hamsters. Behavioural Brain Research, 150(1–2), 201–205]. In that study, animals that were trained at a specific circadian time to discriminate between a “safe” context and one paired with foot shock, showed strong avoidance of the paired context at 24 and 48 h following the last training session, and showed no avoidance at 32 and 40 h following training. In the present study, we hypothesized that this “time stamp” effect is settable to any circadian phase. This was tested by training animals at one of two times of day (ZT13 or ZT4) and testing whether a time stamp would be observed, with avoidance occurring only when training and testing times match. Results confirmed our hypothesis, suggesting that the time stamp in the performance of learned tasks can be set to any circadian phase. Such an ability may allow animals in nature to predict the recurrence of 24 h events, regardless of the time of day the event was encountered. 相似文献

Auditory fear conditioning is one of the most well characterized models used in studies of learning and memory. In order to ensure the animals have been conditioned to fear the auditory stimulus, animals are generally tested for their response to this stimulus in a different context to that used for training. For this reason it is often unclear how much contextual fear conditioning the animals also acquire when they are trained. In this study, we have established a protocol for fear conditioning in mice which is explicit for auditory cues; mice trained using this protocol, show a very low fear response to contextual cues encountered during training. We have undertaken analysis to look for potential brain changes associated with this model by measuring levels of the synaptic vesicle protein, synaptophysin, in the basolateral nuclei of the amygdala following auditory fear conditioning. Our results show levels of synaptophysin were significantly higher in mice which learnt to associate the auditory stimulus with fear, in comparison to all non-learning control animals. These findings support the idea that synaptic plasticity associated with formation of fear conditioning to a single specific conditioned stimulus occurs within the basolateral nuclei of the amygdala. Furthermore, our results demonstrate the usefulness of this model in looking for changes in the brain specific for a defined learning event. 相似文献
