同音字族内的听觉通道词频效应与同音字表征的激活

对于同音词家族较大的词汇(例如汉语单音节词), 听觉通道的词汇通达和词汇表征的激活会受同音词汇歧义怎样的影响, 仍不很清楚。本研究采用了两个听觉通道的实验。实验一的听写任务发现在孤立音节的同音字选择上存在歧义的同时还存在同音字族内的高频偏向, 并非随机选择; 实验二的音-字同音判断任务对比同音与不同音条件得到同音促进量, 揭示了孤立音节在激活语音表征时还会引起同音高频字表征的自动激活, 而同音低频字则受到抑制。结果说明存在同音字族内的听觉通道词频效应, 同音的高、中、低频字的表征激活具有不同等性, 导致不穷尽通达, 且同音的最高频字得到更多通达机会。这些发现难以被现有的词汇通达和同音词表征激活模型解释, 文章提出一个能够解释这些听觉通道发现的模型。     

Vocal Features of Conversational Sarcasm: A Comparison of Methods

This study investigated vocal cues that differentiate sarcastic utterances from non-sarcastic utterances. Utterances were drawn from videotapes of participant interviews and arranged on a master tape for analysis. Utterances that were identified as sarcastic by speakers and recognized as sarcastic by listeners were randomly arranged with utterances identified and recognized as non-sarcastic by the same participants. Both sarcastic and non-sarcastic utterances were analyzed by two methods–acoustic analysis and perceptual coding. The acoustic analysis proved slightly more successful than the perceptual coding in discriminating between sarcastic and non-sarcastic utterances. The acoustic analysis indicated that fundamental frequency, frequency range, length of utterance, and total amount of sound significantly discriminated sarcastic from non-sarcastic utterances. The perceptual coding method revealed that pitch range, length of utterance, and total amount of sound significantly discriminated sarcastic from non-sarcastic utterances. Moderate correlations were found between the acoustic and perceptual variables.     

Stress assignment in aphasia: word and non-word reading and non-word repetition

This paper investigates stress assignment in Dutch aphasic patients in non-word repetition, as well as in real-word and non-word reading. Performance on the non-word reading task was similar for the aphasic patients and the control group, as mainly regular stress was assigned to the targets. However, there were group differences on the real-word reading and non-word repetition tasks. Unlike the non-brain-damaged group, the patients showed a strong regularization tendency in their repetition of irregular patterns. The patients' stress error patterns suggest an impairment in retention or retrieval of targets with irregular stress patterns. Limited verbal short-term memory is proposed as a possible underlying cause for the stress difficulties.     

Own-other differences in the realism of some metacognitive judgments

The present study investigated differences in judgments of one's own and others' knowledge (the own-other difference). Consistent with the below-average effect (e.g., Kruger, 1999), our main results showed that the participants gave lower knowledge ratings of their own extent of knowledge than of another person's extent of knowledge (Experiment 1). Furthermore, lower and more realistic judgments were found when the participants judged their own as compared with when judging another person's overall accuracy (frequency judgments) of answering knowledge questions correctly (Experiment 1 and 2). On the basis of these results it is argued that judgmental anchoring may be important also in the context of indirect comparisons, and that previous conclusions of cross-cultural psychology regarding the above-average effect may be oversimplified.     

名词具体性效应的眼动研究

通两个实验考察名词的具体性效应.实验一采用词汇判断法,考察名词的具体性效应.采用2（具体性：具体、抽象）×2（词频：高频、低频）的两因素被试内实验设计.结果表明：低频词存在具体性效应.实验二应用眼动技术,以EyelinkⅡ眼动仪为工具,考察在句子阅读中的名词具体性效应.实验为单因素被试内设计,自变量为句子中目标词的具体性.结果表明：在句子语境条件下,低频词也存在具体性效应,而且这种效应表现在低频词的晚期加工阶段.

记忆编码与特异性效应之间关系的ERP研究

通过事件相关电位（ERPs）探讨了在“学习–再认”模式条件下的记忆编码与特异性效应之间的关系。选择首要特异性特征为深、浅加工,次要特异性特征为高、低词频。研究结果表明,（1）行为数据支持了低频词的再认比高频词更精确;深加工的再认比浅加工更精确,并且深加工存在着显著的字频效应,浅加工没有显著的字频效应。（2）低频词比高频词有更大的ERP晚正成分（LPC）;在低频词条件下,存在着显著的相继记忆效应,随后再认正确的ERPs比随后再认不正确的ERPs更正。因此,加工方式和词频间接地影响着记忆编码的形成。     

Long-term effect of prefrontal lobotomy on verbal fluency in patients with schizophrenia

OBJECTIVE: This study investigated the long-term effects of bilateral prefrontal leukotomy on lexical abilities in schizophrenia subjects. METHOD: we compared performances of leukotomized (LSP), non-leukotomized schizophrenia patients (NLSP) and normal controls, using a test of verbal fluency. Multiple case and triple comparison design were implemented. i.e., the performance of each LSP was compared to that of NLSP and that of a normal control. The sample consisted of four LSP, four NLSP, and four normal subjects. Subjects were matched in sex, age, handedness, and schooling. In Addition, schizophrenia groups were matched in diagnosis and years of hospitalization. Quantitative and qualitative analyses of generated words and errors produced by subjects were carried out. RESULTS: A deficiency in both groups of schizophrenia was observed, although a better performance in LSP patients was detected. CONCLUSION: Intact Lexical ability in LSP indicates its poor relation to the frontal lobe.     

Grammatical aspect,lexical aspect,and event duration constrain the availability of events in narratives

The present study investigates how readers’ representations of narratives are constrained by three sources of temporal information; grammatical aspect, lexical aspect, and the duration of intervening events. Participants read short stories in which a target event with an intrinsic endpoint or not (lexical aspect: accomplishments/activities) was described as ongoing or completed (grammatical aspect: imperfective/perfective). An intervening sentence described either a long or short duration event before the target situation was reintroduced later in the story. The electroencephalogram time-locked to the reintroduction of the target event elicited a larger N400 for perfective versus imperfective accomplishments, and this effect occurred only after short intervening events. Alternatively, the N400 to targets in the activity condition did not vary as a function of grammatical aspect or duration of intervening events. These results provide novel insight into how the temporal properties of events interact to constrain the availability of concepts in situation models.     

The effects of bilateral presentations on lateralized lexical decision

We investigated how lateralized lexical decision is affected by the presence of distractors in the visual hemifield contralateral to the target. The study had three goals: first, to determine how the presence of a distractor (either a word or a pseudoword) affects visual field differences in the processing of the target; second, to identify the stage of the process in which the distractor is affecting the decision about the target; and third, to determine whether the interaction between the lexicality of the target and the lexicality of the distractor ("lexical redundancy effect") is due to facilitation or inhibition of lexical processing. Unilateral and bilateral trials were presented in separate blocks. Target stimuli were always underlined. Regarding our first goal, we found that bilateral presentations (a) increased the effect of visual hemifield of presentation (right visual field advantage) for words by slowing down the processing of word targets presented to the left visual field, and (b) produced an interaction between visual hemifield of presentation (VF) and target lexicality (TLex), which implies the use of different strategies by the two hemispheres in lexical processing. For our second goal of determining the processing stage that is affected by the distractor, we introduced a third condition in which targets were always accompanied by "perceptual" distractors consisting of sequences of the letter "x" (e.g., xxxx). Performance on these trials indicated that most of the interaction occurs during lexical access (after basic perceptual analysis but before response programming). Finally, a comparison between performance patterns on the trials containing perceptual and lexical distractors indicated that the lexical redundancy effect is mainly due to inhibition of word processing by pseudoword distractors.
