Testing memory typically enhances subsequent re-encoding of information (“indirect” testing effect) and, as compared to restudy, it also benefits later long-term retention (“direct” testing effect). We investigated the effect of testing on subsequent restudy and 1-week retention of action events (e.g. “water the plant”). In addition, we investigated if the type of recall practice (noun-cued vs. verb-cued) moderates these testing benefits. The results showed an indirect testing effect that increased following noun-cued recall of verbs as compared to verb-cued recall of nouns. In contrast, a direct testing effect on the forgetting rate of performed actions was not reliably observed, neither for noun- nor verb-cued recall. Thus, to the extent that this study successfully dissociated direct and indirect testing-based enhancements, they seem to be differentially effective for performed actions, and may rely on partially different mechanisms. 相似文献

学习和记忆是个体赖以生存和发展的前提,如何取得好的学习和记忆效果是心理学和神经科学关注的重点。近年来,许多研究揭示奖赏可以促进记忆效果,奖赏对记忆的影响逐渐成为心理学和神经科学的热点研究课题。大脑的中脑多巴胺奖赏系统与海马记忆系统在结构和功能上均有关联。奖赏通过编码和巩固阶段以不同机制对记忆效果产生作用:在记忆编码阶段,奖赏会激活奖赏系统、注意控制系统,将更多认知资源分配给奖赏相关信息,从而促进奖赏信息的记忆效果;在记忆巩固阶段,奖赏会促进多巴胺释放,作用于海马对奖赏相关信息的加工,从而促进奖赏信息的记忆效果。未来研究可以关注奖赏对行为影响的复杂模式和内在奖赏对学习记忆的影响等方面。 相似文献

Talking on a cell phone can impair driving performance, but the dynamics of this effect are not fully understood. We examined the effects of leaving a voicemail message on driving when there are critical driving targets to attend to (crosswalks and pedestrians). Participants engaged in an ecologically-valid “voicemail” task while navigating a virtual environment using a driving simulator. We also examined the potential weakening or strengthening of effects of leaving a voicemail message on driving as the familiarity and predictability of critical targets changed. Participants completed four experimental runs through the same driving environment in a driving simulator. There were two crosswalks, one with a pedestrian entering the roadway and one without a pedestrian and the location of the pedestrian was predictable (the same pedestrian consistently used the same crosswalk) for the first three runs and then unpredictable for the fourth. Half of the participants left voicemail messages using a hands-free headset, while the other half drove in silence. Leaving a voicemail message increased steering deviation and velocity. Drivers who were leaving a voicemail message decelerated for pedestrians in the roadway to a similar speed as drivers who were not leaving a voicemail message, but they were delayed in braking. Drivers who were leaving a voicemail message also had worse memory for roadway landmarks. These effects were relatively stable across runs through the same driving environment, suggesting that familiarity and predictability did not impact the effects of leaving a voicemail message while driving. Therefore, leaving a voicemail message leads to poorer driving behavior; faster speed, variable steering, and worse memory for roadway landmarks. Interestingly, although drivers who were leaving a voicemail message were slower to react to local targets, they slowed as much as drivers who were not leaving a voicemail message and familiarity with the driving environment did not impact the effects of leaving a voicemail message on driving. 相似文献

Perhaps no other topic in recent history has generated such emotionality as the ongoing traumatic memory debate involving alleged reports of physical and sexual abuse. The literature on this topic is replete with reliance on anecdotal statements, unwarranted and grossly overstated generalizations, emotionally laden conclusions, attacks and counterattacks. This state of affairs has resulted in creating a polarization between cognitive memory researchers and clinical researchers who are attempting to resolve the debate through scientific inquiry. Unfortunately, the databases on both sides of the issue are weak. The purpose of this article is to highlight the key issues at the center of this debate in an attempt to move the debate forward. It is argued that resolution of this debate can only be achieved by conducting appropriately designed clinical research with a population of traumatically abused subjects. To achieve this objective, both sides need to suppress their emotional rhetoric, open lines of communication, and engage in cooperative research efforts. This issue is too important for both the field of psychology and society as a whole to remain polarized and unresolved. 相似文献

Few researchers have examined adults’ and children’s incidental recall of color information. In Experiment 1, we examined how well children recalled the colors of items seen in a first aid demonstration. Color recall of objects was above chance levels after three different time delays. However, recall of clothing color was poor. In Experiment 2, we examined whether colors of items from the same category (e.g., items of clothing) were more difficult to remember than distinct items (i.e., belonging to a range of different categories). Children and adults saw 18 items from three different categories. Color recall was above chance levels. The colors of distinct items were recalled more often than the color of category items. The results suggest that color is encoded automatically to some extent. However, participants had difficulty in recalling the color of clothing worn by the experimenter. 相似文献

Five-day-old chicks were accustomed to follow an imprinted object (a small red ball with which they had been reared) that
was moving slowly in a large arena, until it disappeared behind an opaque screen. In experiments, each chick was initially
confined in a transparent cage, from where it could see and track the ball while it moved towards, and then beyond, one of
two screens. The screens could be either identical or differ in colour and pattern. Either immediately after the disappearance
of the ball, or with a certain delay, the chick was released and allowed to search for its imprinted object behind either
screen. The results showed that chicks took into account the directional cue provided by the ball movement and its concealment,
up to a delay period of about 180 s, independently of the perceptual characteristics of the two screens. If an opaque partition
was positioned in front of the transparent cage immediately after the ball had disappeared, so that, throughout the delay,
neither the goal-object nor the two screens were visible, chicks were still capable of remembering and choosing the correct
screen, though over a much shorter period of about 60 s. The results suggest that, at least in this precocial bird species,
very young chicks can maintain some form of representation of the location where a social partner was last seen, and are also
capable of continuously updating this representation so as to take into account successive displacements of the goal-object.

加工水平对不同类型内隐记忆测试的影响 总被引:3,自引:0,他引:3
许多内隐记忆研究表明 ,加工水平影响外显记忆而不影响内隐记忆 ,这样的实验结果被一些研究者认为是外显记忆与内隐记忆系统分离的重要依据之一。实际上 ,内隐记忆研究中的加工水平问题一直存在争议 ,加工水平效应作为两类记忆系统分离的依据是不充分的。在我们的这项实验中 ,结果表明 ,加工水平影响概念样例生成这种内隐记忆测试而不影响知觉辨认测试。 相似文献

Participants ranging in age from 30 to 70 years free-recalled when they had learned public and private items of news. When responses were plotted in terms of age of participant at time of encoding, it was found that peak recall for public items of news was in the period when participants were aged 10 to 19 years whereas peak recall of private items of news occurred in the period when participants were aged 20 to 29 years. A second study confirmed this pattern of an early reminiscence bump for public news. It is proposed that these two components of the reminiscence bump reflect, respectively, a period of formation of generation identity in the second decade of life and a period of formation of intimate relationships in the third decade. 相似文献
