中性词和负性词的纯粹接触效应

纯粹接触效应指刺激的重复呈现能增加个体对该刺激的喜好。该研究考察中性和负性情绪的非新异刺激能否产生纯粹接触效应。首先评定挑选出本身不使人产生偏好倾向的中性和负性词对。实验一、二分别以所选中性词和负性词为材料, 每个词阈下呈现6次或1次, 后进行偏好判断和再认判断。结果发现, 对多次接触的中性词,偏好分数显著高于随机水平, 再认成绩与随机水平无显著差异; 对多次接触的负性词, 偏好分数和再认成绩均与随机水平相比无显著差异。研究表明, 在阈下呈现的条件下, 中性的非新异刺激能产生经典纯粹接触效应, 而负性非新异刺激则无此种效应。负性情绪材料纯粹接触效应的这一特异性可用加工水平模型解释。     

年龄和性别对气味和词汇的语义识别的不同影响

本研究采用基于人口学特征的大规模取样, 通过线索气味识别测验和词汇测验考察了年龄和性别因素对嗅觉功能和语义知识的影响。1497位健康的成人(35岁~95岁)参与了气味识别和词汇熟练性测验。结果表明年龄对两项测验的成绩都有显著的负面影响, 尽管嗅觉测验的年龄效应更大。女性比男性识别出更多的气味且这种效应与年龄无关, 这进一步证实了先前的观察。本文详细讨论了这些发现的意义。     

汉词和图画再认的ERP效应及脑机制

目的：比较汉词与图画材料再认过程中的事件相关电位（ERP）表现并探讨其脑机制。方法：使用经典“学习一再认”实验模式对21名大学生进行测验,同时记录EEG,离线处理后对汉词及图画再认诱发的ERP波形主要成分及新旧效应进行比较。结果：两种材料的再认均诱发出了明显的新旧效应。顶区新旧效应头皮分布基本一致,但图画再认该效应波幅大于汉词再认;两种材料诱发的额区新旧效应有所不同,图画再认该效应为正走向,而汉词再认此效应表现为负走向趋势。结论：汉词与图画再认既存在某种共同的神经加工机制,叉分别涉及一些特异性的神经活动模式。     

负性情绪词语在外显和内隐记忆测验中的定向遗忘效应

以两类具有不同负性情绪强度值的高频汉语双字词为材料,采用项目法定向遗忘范式,探究负性情绪词语在外显和内隐记忆测验中是否存在定向遗忘效应。结果显示,(1)在外显记忆测验中,强、弱负性词均出现了显著的定向遗忘并且弱负性词的定向遗忘效应大于强负性词;(2)在内隐记忆测验中,只有弱负性词出现了显著的定向遗忘,而强负性词则无。可见,内隐记忆测验中的定向遗忘效应对负性信息比外显记忆测验更加敏感。     

The Effects of Positive and Negative Placebos on Human Memory Performances

Two experiments investigated the possible effects of memory-enhancing and memory-impairing placebo capsules (which participants believed to contain active drugs) on participants' performance in a delayed free recall task. In both experiments participants were randomly assigned to either control, positive, or negative placebo conditions, and their memory performance was tested prior to (baseline trial) and after (test trial) the administration of the placebo. Different patterns of results emerged for positive and negative placebos for actual memory performance measures. Whereas negative placebo produces standard placebo effects by impairing both free recall and accuracy scores on test trial, positive placebo does not affect either of these measures (null placebo effect). On the other hand, both positive and negative placebos produce standard placebo effects with respect to participants' self-reports of perceived changes in memory performance: those in the positive placebo group tend to report that the “drug” improved their performance, and those in the negative group tend to report that it impaired it.     

负性情绪对不同语义、空间关系联结记忆的影响

以负性项目-中性场景以及中性项目-中性场景组成的图片对为材料,通过操控项目-场景之间的语义联系和空间距离,考察了负性情绪对不同语义、空间关系联结记忆的影响。结果显示,当项目-场景空间距离较近时,无论项目-场景之间的语义是否相关,负性情绪始终不会影响项目-场景联结记忆;当项目-场景空间距离较远且语义不相关时,负性情绪会削弱项目-场景联结记忆;而当项目-场景空间距离较远且语义相关时,负性情绪会促进项目-场景联结记忆。结果表明,负性情绪对项目-场景联结记忆的影响会受到项目与场景之间语义关系和空间关系的调节,且语义关系在项目-场景空间距离较远时的作用更为突出。     

汉语字词识别中词频和语义透明度的交互作用

该研究通过词汇判断作业考察了中文双字合成词的心理表征问题。目标刺激为高频透明、高频不透明、低频透明、低频不透明词各12个和48个假词,被试任务为即既又准的判断目标刺激是否是一个词。结果发现,高频词的词汇判断速度快于低频词,透明词的词汇判断速度快于不透明词,词频和语义透明度有显著的交互作用。透明度对低频词的识别所起的作用大于对高频词的识别所起的作用。     

A Developmental Evaluation of Frequency Memory for Actions Presented in Lists,Scripts, and Stories

Although some research suggests that misinformation provided by a co-witness could be more influential than that obtained from other sources, most of this research has compared the effect of co-witness information against non-social forms of misinformation only. To better understand the influence of co-witnesses we compared the influence of co-witness misinformation with the influence of misinformation provided by an interviewer. Across two experiments using the MORI paradigm we found no evidence that a co-witness is particularly influential relative to another social source of post-event misinformation. In fact, the source of the misinformation delivered by our interviewer was less likely to be correctly recalled than the source of the misinformation delivered by a co-witness. There was some evidence that misinformation delivered by both a co-witness and an interviewer has a stronger effect on witnesses' accuracy and confidence than misinformation obtained from either source alone. Finally, our results suggest that the opportunity to provide an early individual memory account might protect against the effect of subsequently-encountered co-witness misinformation. These results have important implications for the way that criminal investigations are conducted.     

Positive,Negative, and Neutral Peer Interactions as Indicators of Children's Social Competency: The Issue of Concurrent Validity

Many studies examining the effects of treatments for socially isolated/withdrawn children have used behavioral measures to assess children's peer relations. In an attempt to examine the concurrent validity of these measures, we observed 258 preschool children during free play and coded their interactions into the categories of positive, negative, and neutral behaviors. We also interviewed these children individually, using a sociometric nomination procedure, and asked them to indicate liked and disliked peers. Our examination of the results revealed that, consistent with other research, the correlation between the sociometric measures and the children's total rate of interaction with peers was low. In addition, measures of positive, negative, and neutral behaviors were also only weakly correlated with the children's sociometric scores. We agree with others in concluding that multiple methods of assessment are needed to properly assess the adequacy of children's peer relations.     

Constructing Semantic Models From Words,Images, and Emojis

A number of recent models of semantics combine linguistic information, derived from text corpora, and visual information, derived from image collections, demonstrating that the resulting multimodal models are better than either of their unimodal counterparts, in accounting for behavioral data. Empirical work on semantic processing has shown that emotion also plays an important role especially in abstract concepts; however, models integrating emotion along with linguistic and visual information are lacking. Here, we first improve on visual and affective representations, derived from state-of-the-art existing models, by choosing models that best fit available human semantic data and extending the number of concepts they cover. Crucially then, we assess whether adding affective representations (obtained from a neural network model designed to predict emojis from co-occurring text) improves the model's ability to fit semantic similarity/relatedness judgments from a purely linguistic and linguistic–visual model. We find that, given specific weights assigned to the models, adding both visual and affective representations improves performance, with visual representations providing an improvement especially for more concrete words, and affective representations improving especially the fit for more abstract words.     

Memory for Related and Unrelated Words: Further Evidence on the Influence of Semantic Factors in Immediate Serial Recall

A number of recent studies have explored the role of long-term memory factors in memory span tasks. The effects of lexicality, frequency, imageability, and word class have been investigated. The work reported in this paper examined the effect of semantic organization on the recall of short lists of words. Specifically, the influence of semantic category on immediate serial recall and the interaction of this variable with articulatory suppression was investigated in three experiments. Experiment 1 compared immediate serial recall performance when lists comprising items from the same semantic category were used (homogeneous condition) with a situation where lists held items from different semantic categories. Experiment 2 examined the same conditions with and without articulatory suppression during item presentation, and Experiment 3 reproduced these conditions with suppression occurring throughout presentation and recall. Results of all three experiments showed a clear advantage for the homogeneous condition. Experiments 2 and 3 showed that the homogeneous category advantage did not depend on the articulatory loop. Furthermore, error analysis indicated that this effect was mainly attributable to better item information recall for the homogeneous condition. These results are interpreted as reflecting a long-term memory contribution to the recall stage of immediate serial recall tasks.     

Attention to Positive and Negative Social-Evaluative Words: Investigating the Effects of Social Anxiety,Trait Anxiety and Social Threat

The study investigated how attention to negative (threatening) and positive social-evaluative words is affected by social anxiety, trait anxiety and the expectation of social threat. High and low socially anxious individuals carried out a modified dot-probe task either while expecting to give a speech or under non-threatening conditions. High socially anxious individuals showed no significant attentional bias towards or away from social-evaluative words. This result significantly contrasted with an identical design that showed avoidance of emotional faces in high socially anxious participants drawn from the same population (Mansell et al ., 1999). Participants who expected to give a speech showed less attentional avoidance of negative and positive social-evaluative words. High trait anxiety was associated with selective attention to negative relative to positive social-evaluative words, consistent with earlier findings of attention to threat cues in high trait-anxious individuals. Implications for designing attention tasks and attentional bias across different dimensions of anxiety are discussed.     

Negative Life Events, Patterns of Positive and Negative Religious Coping, and Psychological Functioning

Religious coping may or may not be adaptive depending upon whether such coping is positive or negative. We investigated the potential moderating effects of positive and negative religious coping patterns on the relationship between negative life events and psychological functioning. Questionnaires included measures of negative life events, positive and negative religious coping, and psychological functioning, and were completed by 336 adult, Protestant church members. Even after controlling for religious participation, negative events were related to increased use of positive and negative religious coping and decreased psychological functioning. Moreover, negative events and positive religious coping produced an interaction effect on depression, such that the high use of positive religious coping buffered the deleterious effects of negative events.     

Memory for Words as a Function of Spelling Transparency

The authors investigated the impact of spelling transparency on memory for words written in Persian orthography. Adult Persian university students (N = 212) performed in a memory recall experiment on 160 monosyllabic words printed on 8 cards (20 on each card) manipulated for spelling transparency, frequency, and imageability. Each card was presented randomly to the participants and they were asked to read the words aloud as quickly as possible. After reading each card, the participants were asked to engage in a digital addition task for 20 s (as a distracter), which was immediately followed by a request to write down as many words as possible from the cards in 40 s. No significant difference was found in the time to name aloud the opaque and transparent words, whereas on the memory recall task there were main effects for spelling, frequency, and imageability and significant 2-way and 3-way interactions. The effects were greatest for transparent spellings when they were of high frequency and high imageability or low frequency and low imageability. The implications of these findings are discussed.     

The Short-Term Memory of Profoundly Deaf People for Words,Signs, and Abstract Spatial Stimuli

The short-term memory (STM) of 25 deaf and 20 hearing adults fluent in Australian Sign Language (Auslan) was tested using both free- and serial-recall versions of three tasks. On two tasks, where stimuli were presented as either written words or Auslan signs, hearing subjects performed significantly better than deaf subjects. This difference was attributed to the facility of the hearing subjects in translating these two classes of language-based stimuli into phonological codes, which have a preferred status in STM. On the third, language-free task, which was an adaptation of the Corsi Blocks test, the deaf and hearing subjects performed at comparable levels, indicating that differences in their STM became evident only with the introduction of language-based factors. Analyses restricted to the deaf subjects showed that performances on the language-based STM tasks correlated positively with scores on a reading comprehension test. Also, deaf subjects who reported an oral education outperformed their counterparts, who reported a total communication (oral plus signed English) education on the language-based STM tasks. Thus, for this diverse adult deaf sample, proficiency in STM for language-based material, skill in reading, and report of an oral rather than total communication education appear to covary.     

Positive and Negative Timelines: A Technique for Restorying

Families or individuals requesting therapeutic consultation often present in the context of an overwhelming history of stressful and negative life events. Frequently, the pressure of such events obliterates memories of strengths and successes. This is particularly true by the time people reach inpatient psychiatric settings. This article outlines a technique designed to help people bring these events into perspective and to develop positive life stories. The use of Positive and Negative Timelines helps to reinforce competency-based themes in people's lives. A clinical case is used to highlight the technique.     

Lexical Association and False Memory for Words in Two Cultures

This study examined the relationship between language experience and false memory produced by the DRM paradigm. The word lists used in Stadler, et al. (Memory & Cognition, 27, 494–500, 1999) were first translated into Chinese. False recall and false recognition for critical non-presented targets were then tested on a group of Chinese users. The average co-occurrence rate of the list word and the critical word was calculated based on two large Chinese corpuses. List–level analyses revealed that the correlation between the American and Taiwanese participants was significant only in false recognition. More importantly, the co-occurrence rate was significantly correlated with false recall and recognition of Taiwanese participants, and not of American participants. In addition, the backward association strength based on Nelson et al. (The University of South Florida word association, rhyme and word fragment norms, 1999) was significantly correlated with false recall of American participants and not of Taiwanese participants. Results are discussed in terms of the relationship between language experiences and lexical association in creating false memory for word lists.     

The Relationship Between Trust-in-God,Positive and Negative Affect,and Hope

We aimed to test the relationships between Trust-in-God, positive and negative affect, and feelings of hope. A sample of university students (N = 282, 50 % female) completed the Positive and Negative Affect Schedule, the Adult Dispositional Hope Scale, and a Persian measure of Trust-in-God for Muslims. The results of a series of hierarchical regression analyses indicated that Trust-in-God was positively associated with participants’ scores for hope and positive affect but was negatively associated with their scores for negative affect. The results support the relationship between Trust-in-God and indices of mental health.     

Integration of Positive and Negative Affective Stimuli

The research reported in this article examines how multiple affective stimuli of differing valence (i.e., both positive and negative) are integrated into an overall affective response. Prior research on the integration of positive and negative information has not focused on affect, and previous affect integration research has not considered both positive and negative feelings. Two experiments investigate how positive and negative affective stimuli combine to influence overall affective responses to an advertisement, content‐specific beliefs, and overall ad evaluations. Both recency and contrast effects were observed on positive affective response and positive beliefs, but comparable effects on negative affective response and negative beliefs were not evident. The results support a motivational influence of affect on judgments.     

Effects of Negative Campaigning on Vote,Semantic Differential,and Thought Listing1

In 3 studies, subjects were asked to vote on all positively described candidate vs. an opponent with a 1-sentence negative. In Study 1, the ail-positively described candidate was voted for more often, was rated higher on 10 of 13 semantic differentials, and generated more positive and less negative thoughts. In Studies 2 and 3, the positively described candidate was voted for more, was rated higher on the semantic differentials, and generated more positive and less negative thoughts in the regular negative condition. In the condition in which an independent nonpartisan committee declared the negative groundless, there was no significant difference in any dependent variables. These theories have important theoretical implications related to Johnson-Cartee and Garramone's theories.
