网络成瘾者不同情绪状态下的认知加工特征

取在校大学生454人,通过《青少年病理性互联网使用量表》（Adolescent Pathological Internet Use Scale, APIUS),筛查出网络成瘾者31名为实验组,随机抽取样本中其他非成瘾大学生31人为对照组。使用词首－词尾对应三重意义组合图片60个为实验材料,用人物图片为情绪启动刺激,研究被试在不同情绪状态下的认知选择,记录被试选择词组性质和反应时间。研究发现,所有被试对积极词语的选择最多,对消极词语的选择最少,表现出“趋乐避苦”的认知选择倾向;成瘾组被试对积极词语的选择比对照组少,但是对消极词语选择比对照组多。悲伤启动情况下,成瘾组被试对积极词语的选择比对照组少,但是对消极词语的选择则比对照组多。成瘾组被试对积极信息的选择速度比对照组慢,但是对中性信息和消极信息的选择速度则比对照组快。愉快情绪启动下,成瘾组被试的反应时间比对照组短,在悲伤情绪启动下,成瘾组被试的反应时间比对照组长。悲伤情绪启动下,成瘾组被试对积极词语的反应时间比对照组慢,但是对消极词语的反应时间比对照组快。这些研究结果对网络成瘾的治疗有重要的参考价值。     

材料呈现方式对大学生分类活动影响的眼动研究

使用ASL504型眼动仪,采用2×3的混合实验设计,记录和分析24名被试在两种材料呈现方式下,对图片分类结果和分类过程中的眼动数据。结果表明:(1)大学生分类结果存在显著的呈现方式差异,但不存在显著的材料类别差异。(2)大学生在分类过程中的兴趣区数目、注视时间、注视次数、注视频率、注视点持续时间等眼动指标存在显著的呈现方式差异,但材料类别差异不显著。     

中英文词语刺激的情绪启动效应研究

本研究目的在于以中英文情绪词为启动刺激,考查它们情绪启动的效果是否存在差异。研究采用多媒体投影仪,以汉语感情色彩评定词库中的9个词语和自编的英语感情信息评定表中的9个单词为情绪启动的刺激材料,采取阈上掩蔽的方式,用幻灯片呈现启动刺激。随机选取6个班的大学生被试,共218名,分别接受积极中文词语组、积极英文词语组、中性中文词语组、中性英文词语组、消极中文词语组和消极英文词语组的实验处理,在启动刺激呈现完后进行情绪自评,即让被试填写情绪自评量表。结果发现:不同情绪材料形式(中文词语和英文词语)的情绪启动效应之间差异不显著。     

呈现形式对于空间工作记忆的影响

实验1比较了被试通过图片和文字布局示意两种呈现形式学习空间布局信息之后进行空间定位的成绩比较,结果发现两种条件下被试在正确率上没有显著差异,但是图片示意的反应比文字示意要快.实验2比较了文字故事叙述和文字布局示意两种呈现形式的空间定位成绩,两种条件下的正确率和反应时没有显著差异.而朝向效应在三种呈现形式条件下均有出现.所以,通过各种呈现形式获得的纯粹的空间信息在工作记忆中的存储机制是相同的.     

情绪Stroop效应：威胁驱动还是反应偏差？

为了考查情绪Stroop效应的产生机制是威胁驱动还是反应偏差,本研究进行了两个实验.实验一用一般负性情绪词语和中性词语作为实验材料,实验二用威胁性的情绪图片和中性图片作为实验材料.每个实验均要求一组被试做按键反应,另一组被试做摇杆反应.结果发现,当实验材料为词语时,未出现情绪Stroop效应;当实验材料为威胁性图片时,无论是趋向性反应方式还是回避性反应方式,都出现了情绪Stroop效应.本研究结果支持威胁驱动机制.     

“找茬”任务中的视野偏好与参照策略

通过四个实验系统探讨了"找茬"任务中的视野偏好(左右侧偏好与上下侧偏好),即个体偏好点击或标记哪一侧来确认发现的差异。实验1A要求被试用圆珠笔圈出A4纸上左右并排呈现的两幅图片的差异,实验1B任务相同,图片采用上下排列方式。实验2A和2B的任务同上,区别在于实验刺激呈现在电脑屏幕上,且通过眼动仪记录被试在"找茬"任务中的眼动行为。总体结果表明,个体在比较上下排列的图片时,存在使用上方图片作为参照点的倾向,但在左右比较中整体上无明显的参照视野偏好。     

材料类型和颜色典型性影响颜色-物体Stroop效应

通过两个实验考查材料类型和颜色典型性对颜色-物体Stroop效应的影响。实验1,考查颜色-物体（图片）Stroop效应。结果颜色典型性差异显著,命名图片的颜色和图片的名称都产生显著的颜色-物体Stroop效应。实验2,考查颜色-物体（词语）Stroop效应。结果颜色典型性差异显著,命名词语的颜色产生颜色-物体Stroop效应,命名词语的名称未产生颜色-物体Stroop效应。结论,材料类型和颜色典型性影响颜色-物体Stroop效应。     

感知觉加工与概念加工对联结记忆中图片优势效应的影响

本研究采用联结再认范式考察联结记忆中感知觉水平和概念加工程度对图片优势效应的影响。实验1通过呈现清晰或模糊的词语或图片对操纵了感知觉水平,结果发现只有在清晰条件下图片优势效应才会出现;实验2则在模糊条件下通过要求被试想象两个项目之间的关系操纵了概念加工程度,结果发现在有概念加工条件下,出现了图片优势效应。研究结果表明：（1）降低的感知觉水平会导致联结记忆中的图片优势效应消失;（2）对模糊项目对进行概念加工会使联结记忆中出现图片优势效应。     

Stimulus generalization along a dimension based on a verbal concept

The present study examined generalization along a dimension based on a verbal concept of occupational status. The status dimension was scaled by students who placed occupation names into five status categories, Category 1 representing highest status and Category 5 the lowest status. In two experiments, key presses by students were occasionally reinforced when a slide showing an occupation name from Status Category 3 was present. For half the subjects, key presses were not reinforced during a name from Category 1; for the other half, presses were not reinforced during a name from Category 5. Occupation names from all status categories were later singly presented. In this generalization test, subjects typically divided the dimension into two parts, responding alike to all names within each part. The results suggest that generalization along a dimension in humans is mediated by a subject's verbal classifications of stimuli.     

Specifying levels of processing

This study examines the nature of stimulus processing under semantic and nonsemantic orienting instructions. Two experiments are reported in which subjects were presented with a series of trials each beginning with the presentation of a “decision word” about which they made either a semantic or non-semantic orienting decision. This decision was followed by a word in coloured ink whose colour subjects were required to name as quickly as possible. On half the trails the coloured word was the primary associate of the decision word whilst on the other half the two words were normatively unrelated. On completion of the experiments the subjects were given an unexpected free recall test. The semantic orienting condition led to longer colour naming latencies on associate trials whilst no such difference was found in the non-semantic condition. The semantic condition also produced higher levels of incidental recall although paradoxically an analysis of associative clustering in recall failed to show any difference between the two orienting conditions. The results are interpreted as support for the “Levels of Processing” approach to memory since they provide an index of processing depth which is independent of retention performance.     

Reaction time to temporally-displaced phoneme targets in continuous speech.

In seven experiments, reaction time (RT) was recorded to phoneme targets in sentences. By means of tape splicing or other experimental interventions preceding the target, speech information was or was not discarded, and targets were either temporally displaced "early" or "late" or remained on time." RT to displaced targets was slower than to on-time targets, except when the tape-splicing manipulation in effect presented coarticulatory target information in advance, in which case RT was faster than RT to on-time targets. The latter manipulation also produced faster RT than RT to the same targets in the original sentence, that is, that containing no experimental intervention at all. In three of the experiments, half the targets were contained in stressed syllables, half in unstressed syllables. Stressed and unstressed targets were affected differently, depending upon practice and other factors. Results were interpreted in terms of listener expectancies based on timing redundancy in continuous speech. They indicate an interaction between the effects of segmental and suprasegmental cues during ongoing perception.     

Gender Roles and Pressure to be Truthful: The Bogus Pipeline Modifies Gender Differences in Sexual but Not Non-sexual Behavior

Previous studies have indicated that the research context has an influence on whether gender differences are found in sexual behavior, likely due to adherence to different gender norms for men and women. The present study utilized bogus pipeline methodology to help determine if the purported use of a lie detector would influence gender differences in reports of other types of behaviors considered more suitable for one gender or the other. Participants consisted of General Psychology students attending a regional campus of a major Midwestern university in the United States. Approximately half of 293 participants completed a questionnaire while connected to non-functioning lie detection equipment and the other half completed the questionnaire after the equipment had been disconnected. There were interactions between gender of participant and testing condition for sexual behavior but not for other types of common behaviors considered more appropriate for one gender or the other. This suggests that there is something specific to sexual behavior with regard to a differential willingness between men and women to report behavior unless there is pressure to be honest. Hypergender ideology was related to reports of sexual behavior (but not nonsexual behavior) only for men in the bogus pipeline condition, lending further support to the idea that gender role expectations influence reports of sexual behavior more than reports of other types of behavior.     

Observer states and traits and the imitative process: A test of a new formulation

In three studies the formulation was tested that characteristics of the observer have an effect on imitation only in situations which provide little information concerning appropriate or expected behaviors. In Experiment I, female college students of high, medium, and low need for social approval underwent either a high or low arousal manipulation. Subjects observed a videotaped model who engaged in a size judgment task. For half the subjects the model received verbal reward (high information); for the other half the model received no feedback (low information). Subsequently, the model and subject responded alternately in the task during which no feedback was given. Neither need for social approval nor manipulated arousal was found to be systematically related to imitation in either information condition. However, the hypothesized relationships were found when subjects' arousal or anxiety levels were determined by self ratings. These results were replicated in a second, similar experiment. In a third experiment, which involved an improved arousal manipulation, the hypothesized relationships were confirmed.     

Victimization and delinquency among Canadian youth.

This study examined the extent of victimization and delinquency in the past year among 962 junior and senior high school students in a large Canadian city. The incidence of having a weapon at school was also investigated. Further, relationships between victimization, delinquency, and weapon possession were explored. The prevalence of self-reported victimization was found to be high, both while the youths were at school and while not at school. Except for victimization of a sexual nature, males reported higher rates of victimization, in and out of school, than did females. In general, younger students reported higher rates of victimization at school than did older students. In addition, over half of the students reported engaging in some form of delinquent behavior within the past year. Males, as compared with females, were more likely to report engaging in a variety of delinquent behaviors. Interestingly, students in grade 9 were more likely to report delinquent behaviors than were students in other grades. Students who reported moderate/high levels of delinquency were more likely to report moderate/high levels of victimization, and students who reported no delinquency were more likely to report no victimization.     

Second-Guessing the Jury: Stereotypic and Hindsight Biases in Perceptions of Court Cases1

This research examined the effects of stereotypic beliefs and hindsight biases on perceptions of court cases. Subjects read evidentiary material pertaining to a criminal trial in which the defendant either was a stereotyped offender or was not. Additionally, some subjects were given outcome information about the verdict attained in the trial; half of these subjects were told that the defendant had been found guilty, and the other half were told that he had been found not guilty. The remainder were not given any outcome information. Subjects were than asked to predict the likely outcome of a trial based on the presented evidence. Typical hindsight bias effects were expected and obtained for nonstereotyped offenders; subjects considering these cases viewed the evidence as less incriminating when they were told the defendant had been found not guilty, and they found it to be more incriminating when they were told the defendant had been found guilty, when compared to the no-outcome-information group. However, no hindsight biases were evident in judgments of cases involving stereotyped defendants, who were seen as relatively more likely to be guilty regardless of the nature of outcome information presented. Particularly striking was the lack of impact of the “not guilty” outcome information on perceptions of the guilt of stereotyped defendants. These findings suggest that strong expectations held in foresight may not be amenable to modification in hindsight.     

A Cross-cultural Perspective on Judgments of Woman-to-woman Sexual Harassment: Does Sexual Orientation Matter?

We investigated perceptions between Brazilian and U.S. college students regarding a hypothetical case involving woman-to-woman sexual harassment in which the sexual orientation of both the target and the alleged harasser was experimentally manipulated. Thus, there were four different scenarios, which were randomly given to 952 college students (89% of whom reported to be White). We found that the scenario that depicted heterosexual woman-to-heterosexual woman sexual harassment was rated as the least likely to be sexual harassment, to need an investigation, and to be punishable than the other scenarios. Generally, Brazilians viewed the case as more likely to be sexual harassment and to need an investigation than did U.S. respondents. In the U.S., women perceived the case as more likely to be sexual harassment, to need an investigation, and to be punishable than men did; however, no such gender differences were found in Brazil. Lastly, hostile sexism and perceptions of woman-to-woman sexual harassment predicted respondents rating the case as sexual harassment and in need of an investigation.     

The eyebrow frown: a salient social signal

Seven experiments investigated the finding that threatening schematic faces are detected more quickly than nonthreatening faces. Threatening faces with v-shaped eyebrows (angry and scheming expressions) were detected more quickly than nonthreatening faces with inverted v-shaped eyebrows (happy and sad expressions). In contrast to the hypothesis that these effects were due to perceptual features unrelated to the face, no advantage was found for v-shaped eyebrows presented in a nonfacelike object. Furthermore, the addition of internal facial features (the eyes, or the nose and mouth) was necessary to produce the detection advantage for faces with v-shaped eyebrows. Overall, the results are interpreted as showing that the v-shaped eyebrow configuration affords easy detection, but only when other internal facial features are present.     

Sexual fantasizing in males and females

Sexual fantasizing during intercourse, masturbation, and nonsexual activity was examined in 30 males and 30 females, American students at Tel-Aviv University. Each subject responded individually to questionnaires involving general background information, sexual activity, daydreaming frequency and attitudes toward daydreaming, and a sexual fantasy scale. The results indicated that virtually no man or woman denied having sexual fantasies. Any observable sex differences were in kind rather than amount of fantasy. Women had more submission fantasies, whereas men reported more performance fantasies. This difference was interpreted as reflecting social sexual stereotypes. In support of a cognitive skill model, it was found that sexual fantasizing proliferates along with increases in both sexual and daydreaming experience. Sexual passivity was related to a greater degree of fantasizing during sex. On the whole, the findings suggest that sexual fantasizing is a universal occurrence which in itself is not necessarily related to psychopathology.
