对1330名初中生进行间隔一年的追踪测试,通过交叉滞后的方法探讨亲子冲突、朋友冲突和孤独感之间的相互作用。结果发现,对男生而言,先前亲子冲突对随后朋友冲突和孤独感预测作用不显著,而朋友冲突与孤独感为相互预测关系,亲子冲突和朋友冲突不存在显著预测关系;对女生而言,先前亲子冲突可以显著正向预测随后孤独感,而朋友冲突则不能,亲子冲突与朋友冲突为相互预测关系。结论:朋友冲突对男生的孤独感影响更大,亲子冲突对女生的孤独感影响更大。 相似文献

Two experiments examined the effects of event modality on children's memory and suggestibility. In Experiment 1, 3- and 5-year-old children directly participated in, observed, or listened to a narrative about an event. In an interview immediately after the event, free recall was followed by misleading or leading questions and, in turn, test recall questions. One week later children were reinterviewed. In Experiment 2, 4-year-old children either participated in or listened to a story about an event, either a single time or to a criterion level of learning. Misleading questions were presented either immediately or 1 week after learning, followed by test recall questions. Five-year-old children were more accurate than 3-year-olds and those participating were more accurate than those either observing or listening to a narrative. However, method of assessment, level of event learning, delay to testing, and variables relating to the misled items also influenced the magnitude of misinformation effects. 相似文献

Two-action tests of imitation compare groups that observe topographically different responses to a common manipulandum. The
general aim of the two experiments reported here was to find a demonstrator-consistent responding effect in a procedure that
could be elaborated to investigate aspects of what was learned about the demonstrated lever response. Experiment 1 was a pilot
study with rats of a variant of the two-action method of investigating social learning about observed responses. Groups of
observer rats (Rattus norvegicus) saw a demonstrator push a lever up or down for a food reward. When these observers were subsequently given access to the
lever and rewarded for responses in both directions, their directional preferences were compared with two 'screen control'
groups that were unable to see their demonstrators' behaviour. Demonstrator-consistent responding was found to be restricted
to observers that were able to see demonstrator performance, suggesting that scent cues alone were insufficient to cue a preference
for the demonstrators' response direction and thereby that the rats learned by observation about body movements (imitation)
or lever movement (emulation). Experiment 2 assessed responding on two levers, one that had been manipulated by the demonstrator,
and a second, transposed lever positioned some distance away. Demonstrator-consistent responding was abolished when actions
were observed and performed in different parts of the apparatus, suggesting that observed movement was encoded allocentrically
with respect to the apparatus rather than egocentrically with respect to the actor's body. With particular reference to the
influence of scent cues, the results are discussed in relation to the strengths and weaknesses of this and other varieties
of the two-action procedure as tests of imitation in animals and human infants.

本研究通过考察合体字和复合词加工过程中联结记忆和项目记忆的变化,探究了在将不同项目绑定为整体的过程中联结编码和项目编码间的关系,并结合脑电技术比较了合体字和复合词的加工过程在神经机制上的差异。行为结果显示:与不能组成字或词的编码条件相比,合体字和复合词编码条件下的联结记忆成绩有显著提升,且项目记忆成绩没有下降;与复合词编码相比,合体字编码条件下的联结记忆和项目记忆成绩都显著更好。脑电结果显示:复合词编码时晚期负成分(LNC)主要位于额区且发生较早,而合体字编码时的LNC主要位于枕区且发生更晚;合体字编码比复合词编码在α/β频段的神经振荡去同步化更强。这些结果表明,将不同项目绑定为整体的操作可以强化大脑对联结信息的加工,同时不会损害对项目的加工,支持了“只有收益”的观点。本研究也从实证的角度为汉语学习材料的编排提供了参考。 相似文献

Research showed that source memory functioning declines with ageing. Evidence suggests that encoding visual stimuli with manual pointing in addition to visual observation can have a positive effect on spatial memory compared with visual observation only. The present study investigated whether pointing at picture locations during encoding would lead to better spatial source memory than naming (Experiment 1) and visual observation only (Experiment 2) in young and older adults. Experiment 3 investigated whether response modality during the test phase would influence spatial source memory performance. Experiments 1 and 2 supported the hypothesis that pointing during encoding led to better source memory for picture locations than naming or observation only. Young adults outperformed older adults on the source memory but not the item memory task in both Experiments 1 and 2. In Experiments 1 and 2, participants manually responded in the test phase. Experiment 3 showed that if participants had to verbally respond in the test phase, the positive effect of pointing compared with naming during encoding disappeared. The results suggest that pointing at picture locations during encoding can enhance spatial source memory in both young and older adults, but only if the response modality is congruent in the test phase. 相似文献

After 30 years of research, the mechanisms underlying the evaluative priming effect are still a topic of debate. In this study, we tested whether the evaluative priming effect can result from (uncontrolled) associative relatedness rather than evaluative congruency. Stimuli that share the same evaluative connotation are more likely to show some degree of non-evaluative associative relatedness than stimuli that have a different evaluative connotation. Therefore, unless associative relatedness is explicitly controlled for, evaluative priming effects reported in earlier research may be driven by associative relatedness instead of evaluative relatedness. To address this possibility, we performed an evaluative priming study in which evaluative congruency and associative relatedness were manipulated independently from each other. The valent/neutral categorisation task was used to ensure evaluative stimulus processing in the absence of response priming effects. Results showed an effect of associative relatedness but no (overall) effect of evaluative congruency. Our findings highlight the importance of controlling for associative relatedness when testing for evaluative priming effects. 相似文献

记忆编码与特异性效应之间关系的ERP研究 总被引:5,自引:1,他引:4
通过事件相关电位(ERPs)探讨了在“学习–再认”模式条件下的记忆编码与特异性效应之间的关系。选择首要特异性特征为深、浅加工,次要特异性特征为高、低词频。研究结果表明,(1)行为数据支持了低频词的再认比高频词更精确;深加工的再认比浅加工更精确,并且深加工存在着显著的字频效应,浅加工没有显著的字频效应。(2)低频词比高频词有更大的ERP晚正成分(LPC);在低频词条件下,存在着显著的相继记忆效应,随后再认正确的ERPs比随后再认不正确的ERPs更正。因此,加工方式和词频间接地影响着记忆编码的形成。 相似文献

Schatz, T.R., Spranger, T. & Knopf, M. (2010). Is there a memory profit after repeated learning of subject‐performed actions? Comparing direct and long‐term memory performance level as a function of age. Scandinavian Journal of Psychology 51, 465–472. The present two studies investigated the possibility for improvement and maintenance of episodic memory in young and older adults. In a first study, the performance‐enhancing effect of two separate as well as combined learning devices, enactive encoding and repeated learning, was tested. With a time lag of one week, four different series of 30 action phrases were encoded either verbally or by enacting them symbolically. Memory was assessed in four immediate free recall tests. In a second study, the maintenance of the memory profit was tested in an unexpected fifth session half a year later. As expected, there was a steady improvement of memory performance as a function of repeated learning in study one. This holds true regardless of age. In addition, enactive encoding led to a better memory performance than verbal encoding in both age groups. Moreover, younger adults outperformed the elderly regardless of type of encoding. The combination of the two learning devices was not efficient enough to eliminate aging effects in episodic memory. However, memory flexibility is demonstrated also in the elderly. In the long‐term follow‐up, maintenance of learning and memory could be found in all participant groups. 相似文献
