THE EFFECTS OF ALIGNABILITY ON MEMORY 总被引:1,自引:0,他引:1
Abstract— According to structure-mapping theory, the process of comparison in one of alignment and mapping between representational structures. This process induces a focus on commonalities and alignable differences (i.e., those related to the commonalities). Non-alignable differences (i.e., those not related to the commonalities) are held to be neglected. The theory thus predicts increased focus on the corresponding information, Whether these are commonalities or differences. In this article, we explore the implications of this claim for memory: Specifically, we test the prediction that alignable differences are more likely to be processed and stored than nonalignable differences.
We present a study in which people made similarity comparisons between pairs of pictures and then were probed for recall. The recall probes were figures taken from the pictures and were either alignable or nonalignable differences between the pairs. The alignable differences were better memory probes than the nonalignable differences, suggesting that people were more likely to encode and store the corresponding information than the noncorresponding information. 相似文献

意志与意识对记忆的交互影响 总被引:1,自引:0,他引:1
运用加工分离程序,研究了编码和提取时不同意志和意识水平对部首补笔的影响。结果发现:除编码阶段和提取阶段的意志之间不存在交互作用之外,同一阶段和(或)不同阶段的意志和(或)意识之间均存在显著的或非常显著的交互作用。研究表明:意志和意识两个因素对记忆存在复杂影响,在记忆研究中应关注意志因素的作用。研究结果验证了记忆的状态依存性。 相似文献

The effects of a prosthetic memory aid on the conversational content and social skills of dyads with dementia were evaluated. Six individuals with moderate to severe dementia served as either subject or partner in dyads during 5-min conversational probes conducted three times per week in daycare and nursing-home settings. During phases when a memory aid, consisting of personally relevant picture and sentence stimuli, was available, most subjects used their own aid to improve the quality of conversations by increasing the frequency of on-topic statements, diminishing nonproductive utterances, lengthening their conversational turn, and/or increasing the frequency of turns taken. Most partners demonstrated awareness of social discourse conventions by appropriately relinquishing conversational dominance, decreasing both content and nonproductive utterances, and increasing acknowledging or affirmative comments when subjects used memory aids. Naive judges' ratings of aided and unaided conversational samples on seven conversational dimensions reflected differences in perceptions of significant improvement as a function of the conversational discourse style of each dyad. 相似文献

采用DRM范式(Deese-Roediger-Mc Dermott paradigm),考察了启动情绪状态下词表项目的呈现方式对错误记忆的影响。结果发现:(1)启动情绪主效应不显著。(2)词表项目的呈现方式主效应显著。(3)启动情绪与呈现方式间存在交互作用。在愉快启动情绪状态下分组呈现的错误再认率明显高于随机呈现条件;当词表项目分组呈现时,三种情绪状态下的错误再认率有显著差异,其中愉快启动情绪下的错误再认率最高,其次是悲伤情绪,最低的为对照组—非启动情绪状态。说明启动的愉快情绪增强了对关键诱饵的连续激活累积效应,从而导致对关键诱饵较高的错误再认率。 相似文献

认知负荷和控制性注意对工作记忆广度任务成绩的影响 总被引:4,自引:0,他引:4
通过stroop干扰实验严格筛选被试,考察了控制性注意能力不同的被试在加工部分认知负荷不同的工作记忆广度任务中的成绩。结果表明:任务复杂性和加工速度对工作记忆广度任务成绩有重要影响,任务越复杂或加工速度越快,被试的工作记忆广度任务成绩越低;在复杂的和加工速度快的工作记忆广度任务中,控制性注意能力高的被试成绩要好于控制性注意能力低的被试,但在简单的和加工速度慢的任务中两者成绩没有显著差异。 相似文献

再认的两种机制及其与启动效应的关系 总被引:2,自引:1,他引:1
通过两个实验对两种再认所涉及的心理机制及其与启动效应的关系进行探讨。实验一用高频字和低频字作实验材料,分别测量集中注意和分散注意条件下,两种再认的成绩。结果表明:学习阶段的注意分散使以提取为基础的再认成绩下降,对以熟悉性为基础的再认成绩没有影响。低频字以熟悉性为基础的再认优于高频字,但字频对以提取为基础的再认没有影响。实验二分别测量两种再认项目的补笔正确率。结果表明:以熟悉性为基础的再认的补笔正确率显著高于以提取为基础的再认的补笔正确率。据此可以推论:两种再认可能有不同的心理机制。以提取为基础的再认属于有意识记忆的范畴,以熟悉性为基础的再认属于无意识记忆的范畴。后者和启动效应的心理基础可能是共同的。 相似文献

Two experiments examined expectations and bodily sensations in premenstrual symptom reports. Women took a fictitious test that indicated they were either premenstrual or intermenstrual. In Experiment 1, 48 women were studied during their premenstrual phase. In Experiment 2, 82 women were studied during either their premenstrual or intermenstrual phase. Individual differences in retrospective premenstrual distess were assessed prior to the experiments. Both experiments revealed that the higher the woman's retrospective reports of premenstrual distress, the more symptoms she reported in the lab during her premenstrual phase, regardless of what the test indicated. However, women who were told they were premenstrual reported greater symptoms than women who were told they were intermenstrual. In summary, although expectations affect women's symptom reports regardless of their actual phase and history of reported symptoms, premenstrual symptom reports cannot be dismissed as simply expectations, because some women do experience greater symptoms as they approach menstruation. 相似文献

心理表征对正投影问题解决及轴测投影图再认水平的影响 总被引:2,自引:0,他引:2
借鉴内隐记忆的研究范式,采用平面、分离的正投影问题解决及其相应轴测投影图的再认任务,探讨问题表征的结构特征性对空间问题解决和再认水平的影响。实验结果表明,一般在正投影问题获得正确解决时,对其相应的、先前从未见到过的轴测投影图往往也可获得正确再认,而且基于正投影问题获得正确解决条件下的再认水平(PCC)显著地高于那些问题未得获得解决下的再认水平(PCI)。在结合被试口语记录的基础上,研究结果证明:基于正投影图上的问题解决过程是受到一个具有三维结构特性而非正投影图中二维特性心理表征的调节;并且,正是这一具有三维结构特性心理表征的建构,使得对具有相同结构特性的轴测投影图获得了更为有效的再认。 相似文献

THE SIMILARITY OF BRAIN ACTIVITY ASSOCIATED WITH TRUE AND FALSE RECOGNITION MEMORY DEPENDS ON TEST FORMAT 总被引:5,自引:0,他引:5

Abstract— Event-related potentials (ERPs) were compared for correct recognitions of previously presented words and false recognitions of associatively related, nonpresented words (lures). When the test items were presented blocked by test type (old, new, lure), waveforms for old and lure items were different, especially at frontal and left parietal electrode sites, consistent with previous positron emission tomography (PET) data (Schacter, Reiman, et. al., 1996). When the test format randomly intermixed the types of items, waveforms for old and lure items were more similar. We suggest that test format affects the type of processing subjects engage in, consistent with expectations from the source-monitoring framework (Johnson, Hashtroudi, & Lindsay, 1993). These results also indicate that brain activity as assessed by neuroimaging designs requiring blocked presentation of trials (e g, PET) do not necessarily reflect the brain activity that occurs in cognitive-behavioral paradigms, in which types of test trials are typically intermixed. 相似文献

支持性条件对记忆年龄差异的影响 总被引:6,自引:0,他引:6
通过三个实验探讨支持性条件对记忆年龄差异的影响。结果表明,在操作条件下记忆高语义关联度项目时,有缩小记忆年龄差异的作用,(实验一);线索回忆时,对于低语义关联度项目,青年人可从名词线索中获得更多支持(实验二);当使用具范畴组织关系的词表作为记忆材料时,操作条件和范畴线索的结合对老年人记忆有干扰作用(实验三)。记忆中年龄差异的变化反映了编码条件、记忆材料和提取条件三方面的综合作用。 相似文献

MODELING THE EFFECTS OF BANDING IN PERSONNEL SELECTION 总被引:1,自引:1,他引:0
Selection outcomes under banding are affected by characteristics of the selection system and the applicant pool. This study examined the effects of eight parameters on the proportions hired from higher- and lower-scoring groups: (a) selection ratio; (b) reliability; (b) fixed vs. sliding bands; (d) top-down vs. random within-band selection; (e) preferential vs. nonpreferential selection; (f) mean differences; (g) standard deviation differences; and (h) proportion of applicants from the lower-scoring group. Simulation results were analyzed in a fully-crossed eight-way ANOVA. Higher-order interactions among selection system and applicant pool characteristics had virtually no effect on selection outcomes; the proportion of the applicant pool from the lower-scoring group accounted for nearly half the variance in out-comes. Other important effects are, in order, the effects of standard deviation differences, mean differences, preferential hiring, and the selection ratio. Applicant pool characteristics have considerably more influence on selection outcomes than do selection system characteristics. 相似文献

损毁海马对大白鼠学习记忆的影响 总被引:1,自引:0,他引:1
本实验探讨损毁海马对不同巩固水平的暗箱回避条件反射(DAR)产生的影响,以及损毁海马不同部位对DAR的影响。实验结果表明,广泛地损毁海马使条件反射难于巩固;其次,条件反射愈巩固、所受的影响愈小;第三,条件反射遭受破坏的程度,随海马损毁面积大小和部位不同而不同,海马腹部对DAR的影响重于背部的影响。上述结果证明,海马参予了记忆的各个阶段,而在记忆形成的早期阶段则更为重要,海马腹部和背部参予程度有一定差异。 相似文献

工作记忆与领域知识在个体认知行为中的作用 总被引:2,自引:1,他引:1
新近研究表明,工作记忆和领域知识在个体认知行为上起了积极的作用,对二者关系的研究有三种观点:一是强调工作记忆或领域知识在认知行为中的单独作用;二是综合考察二者在个体认知行为中的不同作用;三是建立模型,阐述工作记忆和领域知识在认知行为中的作用。最后针对当前有关此方面的研究,探讨有关工作记忆和领域知识作用研究的发展趋势。 相似文献

This study examined how external evaluators' assessments of a management team and its leader are impacted by congruence between the leader's gender and the gender typing of the industry in which the team works. We experimentally tested our theory using industries that are either male typed or gender neutral, with teams led by male and female leaders. Results indicate that performance expectations for the team were more favorable when the leader's gender was congruent with the industry's gender typing, but expectations for the leader were not affected by gender congruence. These findings paradoxically suggest that evaluators form performance expectations for teams based upon individual characteristics of their leaders, even when these characteristics have no effect on the conscious assessments of the leaders themselves. 相似文献
