Unconscious priming according to multiple S-R rules

The present study investigated if unconscious primes can be processed according to different stimulus-response (S-R) rules simultaneously. Participants performed two different S-R rules, such as judging a digit as smaller or larger than five and judging a letter as vowel or consonant. These S-R rules were administered in random order and announced by a previously presented cue. Each target stimulus was preceded by subliminal primes which afforded a different or an identical response according to either the currently irrelevant or currently relevant S-R rule. In three experiments, we consistently found priming effects according to currently irrelevant S-R rules, even when primes for the relevant and irrelevant S-R rules were presented simultaneously. Thus, unconscious stimuli have the power to activate responses according to currently required and currently not required S-R rules concurrently. The results are in line with response activation accounts of subliminal priming and suggest that at least two routes may gain access on response processes simultaneously.     

The influence of induced mood on the inhibition of emotional information

The ability to inhibit affective information plays a major role in efficient cognitive processing. In this study the effect of mood induction on inhibitory processing of emotional material was investigated. In Experiment 1, performance on a negative affective priming task (NAP) following negative and positive mood induction (MIP) was compared to a neutral mood condition. Results revealed that, as compared with the neutral mood condition, inhibitory function for affective material was unaffected by negative MIP. However, after the positive MIP, inhibitory processes were significantly impaired. In Experiment 2, we replicated and extended the findings on positive affect and inhibition. The data concerning positive mood fit with the general findings that positive mood often leads to a “loose, flexible” processing mode. The null-finding concerning negative mood and inhibition is discussed in the light of research on inhibition in depression.     

刺激类型及表征关系对无意视盲的影响

通过考察刺激类型以及重叠呈现的图片流和词语流的表征关系对非注意刺激的捕获差异,试图考察刺激类型和表征关系对无意视盲（Inattentional Blindness）的影响。分别有20名中学生参加了词和图片基线水平测试,52名中学生参与了无意视盲实验。研究结果表明：（1）当词与图片重叠呈现时,不管注意刺激是词还是图片,也不管词与图片的表征是否一致,与基线水平相比,被试都出现了显著的无意视盲现象。（2）当词与图片的表征意义一致时,如果注意刺激是图片,而非注意刺激是词,那么被试更容易觉察到非注意刺激。（3）非注意刺激与注意刺激表征意义一致时更容易捕获观察者的注意     

再探汉字加工中语音、语义激活的相对时间进程

在Zhou和Marslen-Wilson（2000）基础之上,进一步探讨汉字加工中语音和语义信息激活的相对时间进程及其对汉字加工理论的含义。采用启动范式,用同一目标字与语义相关启动字、同音启动字以及无关控制启动字配对,变化同音启动字读音与其声旁的规则性,变化启动字与目标字呈现之间的时间间隔（SOA,57ms或200ms）,使用两种实验任务（真假字判断和命名）,考察语义、语音效应发生的时间先后与效应量的大小。真假字判断实验发现,不管SOA如何,语义启动效应都非常显著,而同音启动效应则随SOA的增长而逐渐加大,从不显著到显著;同音启动字读音规则性对启动效应没有明显影响。命名实验发现,语义启动、同音启动效应同时存在于长、短SOA条件中。长SOA时,两者在数值上没有显著差异;短SOA时,同音不规则字产生的启动效应等同于语义启动效应,而同音规则字产生的启动效应则大于语义启动效应。结合其它实验发现,这些结果说明,在熟练的汉字加工中,语音信息的激活并不比语义信息早,语音激活也不是语义激活的先决条件;但汉字各种信息激活的相对激活量和时间进程会随任务性质和材料性质而在一定范围内有所改变。     

Software Tools in Logic Education: Some Examples

Computers are increasingly present in education and make manyresources and activities available to teachers and pupils. Newpedagogical resources development is very interesting for both.Our digital library Summa Logicae is overtly involved in innovationand pedagogical systematization. It includes some software toolsfor teaching logic developed by computer science students, andin this article we present two of these tools. The MAFIA toolis especially attractive for first year students and helps themto understand the basic concepts of logic in an interactiveway using sematic tableaux. It also allows them to solve thecrazy cases in Mafia which their fellow students from previousyears proposed. The Modelos de Kripke tool, oriented to a moreadvanced level, serves for understanding the link between theproperties of the accessibility relation and the modal formulas,which is at the basis of the current developments of modal logic.     

老年人阈下情绪对其认知偏向和认知效率影响之比较

为了比较研究老年人的情绪对其认知效率和偏向的影响,随机选取25名正常老年人完成两项实验。一个为情绪STROOP实验,记录被试命名阈下呈现情绪图片（积极、消极和中性表情的人脸图片）后的颜色块的反应时;一个为情绪启动实验,同样呈现情绪图片后紧跟的是人的后脑勺图片,记录被试对后脑勺图片人物的表情猜测。结果发现,相对于中性情绪图片条件,老年人将跟在哭表情图片后的人物更多的猜测为哭;但是只有男性老年人的认知反应时因情绪图片条件而异：消极情绪图片延迟反应,积极情绪图片促进反应。

本研究采用问卷法筛选出创造性思维能力高、低大学生作为被试,利用负启动实验范式考察两组大学生特性负启动效应的异同,探讨汉字特性负启动效应与创造性思维的关系。结果发现：低创造性思维能力组大学生具有显著的特性负启动效应,而高创造性思维能力组大学生则没有产生明显的特性负启动效应。     

句法歧义句理解加工中的语义关联性效应研究

通过实验探讨了汉语直接宾语(DO)/宾语小句(SC)类暂时句法歧义句理解加工中的语义关联性效应。实验采用自定速动窗技术。实验1发现在汉语暂时句法歧义句理解加工中存在语义关联性效应。实验2发现语义关联性与句法歧义性因素在解歧区产生了显著的交互作用。结果表明,语义关联性因素显著影响对句子的理解加工,并且与句法歧义因素共同作用于句子的理解加工过程。     

非熟练中—英双语者跨语言长时重复启动效应

采用跨语言长时重复启动研究范式进一步探讨非熟练中－英双语者的记忆表征模型。被试为华南师范大学大一本科生共140名。实验自变量是语言条件（同语言和跨语言）和学习状况（学习过的和未学习过的）,实验因变量是单词判断的反应时和正确率。实验1中被试在学习和测验阶段都完成概念任务,结果表明获得了跨语言长时重复启动效应。实验2中被试在学习和测验阶段完成词汇任务,结果表明没有获得跨语言长时重复启动效应。实验3中被试在学习阶段完成概念任务,在测验阶段完成词汇任务,结果表明没有获得跨语言长时重复启动效应。实验4中在学习阶段的概念任务中呈现汉语单字词,在测验阶段的词汇任务中呈现英语翻译对等词,结果表明没有获得跨语言长时重复启动效应。总的实验结果表明,在基于内隐记忆的跨语言重复启动的范式下,非熟练中－英双语者的记忆表征支持概念表征共享、词汇表征分离的观点。更重要的是,非熟练中－英双语者需要经由汉语翻译对等词的词汇表征,才能通达英语单词的概念表征,支持了词汇连接模型的观点     

音乐知觉期待的研究述评

音乐知觉期待是音乐时间知觉过程中重要的心理现象,它直接影响音乐作为时间艺术的本质特性。文章主要探讨了和音乐知觉期待相关的以下几方面问题：音乐知觉期待存在的范畴,音乐知觉期待依靠音乐元素的四种期待率,音乐知觉期待存在的两种类别和采用的五种研究范式,音乐知觉期待研究的主要领域（神经生理机制、记忆和启动效应等方面）,以及音乐知觉期待通过音乐时间知觉和时间估计对音乐时间操作的影响。展望该领域今后研究的方向,可以认为,对音乐知觉期待的心理特征和存在条件在音乐时间操作中作用的进一步研究,将在很大程度上揭示音乐时间操作中的普遍现象——计时偏差的真正原因
