内外部线索对学习判断的影响

该研究针对Koriat和Dunlosky实验研究结果的不同,通过两个实验,进一步考察内外部线索对学习判断（judgment of learning,简称为JOL）的影响。被试为山东师大本科生63名。内部线索词对的语义联系,两种外部线索分别是呈现时间和呈现顺序。本研究结果表明：（1）无论在交替呈现还是区组呈现条件下,内部线索对JOL和回忆都产生了显著影响;（2）呈现顺序和呈现时间可能是两种不同类型的外部线索;（3）不同的内外部线索对JOL有不同的交互作用;（4）实验二中无意义词对先呈现组的JOL大于有意义词对先呈现组的JOL,这说明JOL可能存在“锚定效应”。     

线索类型对阈下注视线索效应的影响

实验结合连续闪烁抑制范式和线索化范式, 通过操纵直视面孔和斜视面孔的呈现方式, 考察了动静线索类型对注视线索效应的影响。结果表明：两种线索在阈上条件都能产生注视线索效应, 且动态线索诱发的效应更大; 无意识条件下有且仅有动态注视线索能诱发注视线索效应。这说明眼睛运动是产生阈下注视线索效应的必要条件; 眼睛运动会增强阈上注视线索效应, 静态注视线索效应依赖于意识。研究结果支持了社会知觉与心理理论交互模型。     

任务难度与部分线索效应

部分线索效应是指在学习一个词表后,呈现已学项目中的一部分作为回忆线索去回忆其他项目时,回忆效果反而不如没有线索组的效果好。研究通过三个实验探讨了不同任务难度的部分线索效应。结果表明：（1）在中文词表记忆中存在部分线索效应;（2）随着学习材料难度的提高由部分线索造成的提取成绩的削减量降低。这一研究结果支持了部分线索效应的策略破坏假说。     

自闭症儿童利用社会性注意线索习得词语的眼动研究

本研究采用眼动技术考察18名自闭症儿童利用社会性注意线索习得词语的能力。结果表明：1）自闭症儿童具有利用他人视线习得词语的能力;2）不同视线对自闭症儿童的词语习得产生不同的影响;3）自闭症儿童视线追随行为的潜在机制与普通儿童存在差异,自闭症儿童的视线追随行为可能是意识性的诱发行为而普通儿童则是反射性的自发行为。     

自闭症谱系障碍儿童在多重线索下习得词语的眼动研究

本文利用眼动追踪技术在基线、一致和矛盾3种实验条件下考察感知觉线索和社会性线索在自闭症谱系障碍儿童词语习得中的相对作用。行为数据结果表明, 此类儿童在矛盾条件下选择枯燥物体作为新异词语的所指对象, 这说明社会性线索较之于感知觉线索具有优势作用; 而他们在基线和一致条件下选择有趣物体作为新异词语的所指对象, 且一致条件的词语习得成绩优于基线条件, 这说明社会性线索较之于感知觉线索具有促进作用。眼动数据结果表明, 此类儿童在脸部注视模式和视线追随行为上与普通儿童存在差异。这说明, 虽然社会性线索在此类儿童与普通儿童的词语习得中具有相同的相对作用, 但他们获取社会性信息的方式与普通儿童存在差异。     

FOK的线索熟悉性假说与线索熟悉性判断

这项研究对ＦＯＫ的线索熟悉性假说进行了进一步检验,该假说认为,人们是根据自已对记忆线索是否熟悉而作ＦＯＫ判断的,研究结果表明,线索熟悉性判断与ＦＯＫ判断是两种不同性质的判断,它们可以在相同的刺激模式下表现出不同的反应模式。     

海洛因戒除者对相关线索和负性生理线索的注意偏向

以84名海洛因戒除者和20名正常成人为被试,采用情绪stroop范式探讨了不同康复时相海洛因戒除者对海洛因相关线索和负性生理线索的注意偏向。结果发现,海洛因戒除者对表征与海洛因滥用相关的负性生理线索和表征海洛因使用行为的相关线索存在同等效力的注意偏向,且在不同康复时相内具有稳定性。该研究为解释基于戒除症状的负性情绪对于诱发依赖者药物渴求感和复吸行为的作用及整合基于对相关线索注意偏向的认知加工理论和基于对负性情绪的回避的负强化情绪加工理论提供了实验证据。     

外框数目、线索数目和线索类型对返回抑制的影响

采用被试内重复测量设计和经典的线索—靶子实验范式,考查了外框数目（4和8）、线索数目（1和3）、不同线索类型（on-off线索（即线索出现后消失）、onset线索（即线索持续呈现））对返回抑制的影响,发现靶子潜在位置数目越多反应时越长,返回抑制量越小;线索数目越少反应时越长,返回抑制量越大;onset线索反应时长于on-off线索,onset线索产生的返回抑制量大于on-off线索。这表明空间工作记忆负载和记忆痕迹会影响返回抑制。     

不同相关线索下海洛因成瘾者的反应差异及反应抑制特征：来自ERP的证据

采用ERP技术, 探究海洛因成瘾者在不同相关线索下的脑电反应及其与冲动性的关系。实验采用组间实验设计和双选择Oddball范式, 要求海洛因成瘾组和健康对照组被试对标准刺激与偏差刺激分别做不同的按键反应, 记录他们的EEG数据。结果发现：相比对照组被试, 海洛因成瘾者在观看药物相关线索时诱发的N2波幅更小, P3波幅更大; 在成瘾组内, 相比用药工具线索, 用药动作线索诱发了更小的N2波幅和更大的P3波幅。这表明海洛因成瘾者对药物相关线索存在反应抑制缺陷, 且不同的药物相关线索会激发海洛因成瘾者不同程度的反应抑制缺陷, 用药动作线索比用药工具线索更大程度地影响成瘾者的反应抑制能力, 反映出更高的动作冲动性。     

线索-反应相容性效应和线索有效概率的影响

运用前置线索技术,考察了线索－反应的相容性效应,研究了不同线索与反应的关系和线索有效概率对视觉剌激进行命名反应的时间的影响。结果表明：线索－反应的相容性存在,且符合维度重合理论,支持了相容性是信息加工过程的基本特征;线索客观有效概率影响了线索－反应的相容性效应的强度,线索客观有效概率越高,线索－反应的相容性效应越强。     

Cues to deception

Do people behave differently when they are lying compared with when they are telling the truth? The combined results of 1,338 estimates of 158 cues to deception are reported. Results show that in some ways, liars are less forthcoming than truth tellers, and they tell less compelling tales. They also make a more negative impression and are more tense. Their stories include fewer ordinary imperfections and unusual contents. However, many behaviors showed no discernible links, or only weak links, to deceit. Cues to deception were more pronounced when people were motivated to succeed, especially when the motivations were identity relevant rather than monetary or material. Cues to deception were also stronger when lies were about transgressions.     

Time Cues Block the CS, but the CS Does Not Block Time Cues

Analysis of conditioned defensive freezing in rats revealed that prior pairings of a tone conditioned stimulus (CS) and footshock in Context 1 at Time 1 failed to give that tone CS the power to block conditioning to Context 2 at Time 2. This failure of an excitatory CS to block conditioning of time cues was not reciprocal. When the stimulus roles were reversed, excitatory time cues blocked conditioning to the tone CS. This asymmetry in blocking is best explained by the notion that time cues have special access to the association-formation mechanism.     

Facial Features as Personality Cues

Two studies examined the effects of the appearance of specific facial features on attributions of personality. In Study 1, photographs of men and women were computer-manipulated to have larger than average or smaller than average eye size, and wider than average or narrower than average eye spacing. In Study 2, eye size and mouth fullness were similarly altered. Although it was found that neither eye spacing nor mouth fullness had any effect on perceptions of the targets' personality or physical characteristics, eye size had strong effects in both studies. Analyses of covariance revealed that the personality trait ratings that varied with eye size were mediated primarily by perceived differences in the targets' masculinity-femininity and babyfacedness, and to a lesser extent by attractiveness.     

秩序线索对个体信任水平的影响

人类有追求规则、秩序的本能,有秩序的环境是否能提高人们的信任水平呢？本文的具身性研究思路将社会学中抽象的“秩序”具体化为任务操作,以197名大学生为被试,将其分为三组分别完成秩序程度不同的连线任务,然后通过投资博弈任务测量被试信任水平。结果显示,（1）秩序线索影响信任水平,强秩序线索能提高个体信任水平;（2）秩序线索对信任的影响因个体性别不同而表现出差异,秩序线索的差异只影响女性信任水平;不同秩序条件下的男性信任水平不存在显著差异。     

Single-Letter Retrieval Cues for Anagram Solution

Anagram solution, as related to single-letter retrieval cues and first letter of the solution word (consonant or vowel), was examined. In Experiment 1, college-aged solvers were presented both types of 5-letter words and either the first letter of the solution word as a cue, or no cue. In Experiment 2, the effects of four types of retrieval cues (first, middle, or last letter or no cue) upon solving consonant-beginning words was examined. Finally, Experiment 3 examined the solution of both types of solution words as related to the preceding four types of retrieval cues. The results of all 3 experiments showed that a single letter can be an effective cue. For consonant-beginning words, the middle and last letters were as effective as the first letter. For vowel-beginning words, the first letter was more effective than either the middle or last letter. It was concluded that solvers select one letter of the anagram, typically a consonant, to serve as the first letter of the solution word, and then rearrange the remaining letters.     

基于语言内容的谎言识别

语言内容线索是识别谎言的三种线索之一, 主要分为基于标准的内容分析和真实监控两个模型。语言内容线索模型主要有基于标准的内容分析、真实监控、人际欺骗理论和语言接近度等4种, 这些模型在理论基础、识别标准和识别有效性上各不相同。此外, 年龄、社会技能、幻想倾向、文化差异、事件熟悉度、人际互动和询问策略等因素都会影响语言内容线索的有效性。未来的研究需要从整合模型、发展谎言线索、量化线索等方面进一步完善语言内容线索, 并通过发展主动识别技巧, 结合非语言行为线索以提高语言内容线索识别谎言的正确率。
