本研究采用不同线索强度(强/弱)的中文词对, 选取大学生被试126人, 考察了不同学习方式(重学/测试)在不同时间间隔(5分钟/2天)最终自由回忆测试成绩上的差异。结果发现:在强线索强度词对上, 学习方式主效应显著, 测试条件的回忆成绩在5分钟以及2天后均高于重学条件;而在弱线索强度词对上, 学习方式与间隔时间交互作用显著, 5分钟时重学条件与测试条件的记忆成绩差异不显著, 而2天后测试条件的记忆成绩却显著高于重学条件。结果表明词对的线索强度能够调节测试对不同时间间隔记忆保持的促进作用, 支持了精细提取假设。 相似文献

利用功能性磁共振成像(fMRI)技术探讨文盲和非文盲汉字字形和语音加工脑机制的差异。实验1使用汉字字形和图形比较了中国人文盲和非文盲字形加工过程脑机制的左侧差异。实验2使用汉字语音和纯音比较了文盲和非文盲语音加工过程脑机制的双侧差异。结果表明文盲与非文盲汉字字形和语音加工脑机制不同,且非文盲的脑活动强。 相似文献

本研究采用移动窗口技术,以短文为实验材料,分别以单字呈现和多字呈现两种方式,对阅读技能水平较高和较低的聋生进行了实验,旨在验证和探讨聋生在汉语文章阅读过程中语音编码所起的作用。实验结果发现,聋生在短文阅读过程中存在语音激活的现象,但语音与字形所起的作用在不同实验中表现不同;聋生,特别是阅读能力较高的聋生,在阅读过程中,字形起到了关键的作用。 相似文献

Vihman emphasizes the importance of early word production to the emergence of phonological knowledge. This emphasis, consistent with the generative function of phonology, provides insight into the concurrent representation of phonemes and words. At the same time, Vihman's focus on phonology leads her to possibly overstate the influence of early word acquisition on the emergence of sound categories that are probably purely phonetic in nature at the outset of learning. 相似文献

Appetitive learning has been demonstrated several times using neutral cues or contexts as a predictor of food intake and it has been shown that humans easily learn cued desires for foods. It has, however, never been studied whether internal cues are also capable of appetitive conditioning. In this study, we tested whether humans can learn cued eating desires to negative moods as conditioned stimuli (CS), thereby offering a potential explanation of emotional eating (EE). Female participants were randomly presented with 10 different stimuli eliciting either negative or neutral emotional states, with one of these states paired with eating chocolate. Expectancy to eat, desire to eat, salivation, and unpleasantness of experiencing negative emotions were assessed. After conditioning, participants were brought into a negative emotional state and were asked to choose between money and chocolate. Data showed differential conditioned responding on the expectancy and desire measures, but not on salivation. Specific conditioned effects were obtained for participants with a higher BMI (body mass index) on the choice task, and for participants high on EE on the unpleasantness ratings. These findings provide the first experimental evidence for the idea that negative emotions can act as conditioned stimuli, and might suggest that classical conditioning is involved in EE. 相似文献

汉语形声字语音加工的前词汇通路 总被引:4,自引:0,他引:4
本文利用两个行为实验研究了汉语形声字语音加工的前词汇通路。实验-采用命名作业考察了规则性对汉字形声字语音加工的影响,发现在中、低频字中存在规则性效应;实验二考察了视觉对比度和规则性在形声字语音加工中的作用,发现二者存在显著的交互作用,表明汉字语音加工中也存在词汇前通路。作者还从双通道模型角度对实验结果进行了分析。 相似文献

We investigated the construction of gender in chat groups. Four unacquainted persons chatted in two gender-anonymous conditions and a non-anonymous control condition. In one anonymous condition, the gender focus was made salient. The other groups did not know about the gender focus. All participants had to guess the gender of the others and give reasons for their decisions. Results suggest that (a) overall, 2/3 of gender guesses fit the sex category of the targets, (b) gender anonymity was more comfortable for women, (c) participants used mostly gender-stereotypic cues to infer gender, however, men and women used syntactic, semantic, and pragmatic cues (with different predictive value) to different degrees, (d) conversational behavior varied depending on gender anonymity, and (e) degree of gender salience was irrelevant for the use of gender as an organizing category. 相似文献
