Assessing the Structure of Self-concept: Evidence for Self-defensive Processes by Using a Sentence Priming Task

It was assumed that the definition of traits that are central to the individual self-concept is adapted to individual competencies (self-concept immunization), i.e., skills that individuals believe themselves to be good at are conceived as diagnostic whereas skills that individuals do not possess are considered as less diagnostic. The mental representation of traits was investigated by semantic priming. Targets were self-relevant traits whereas the primes described observable skills that were either semantically related to the target or not. Corresponding to the hypothesis, priming effects were observed for skills that participants believed themselves to possess and that were related to traits central to the self-concept. The pattern was reversed for participants with low self-esteem, thereby underscoring a coping-theoretical interpretation.     

Antecedent priming at trace positions in Japanese long-distance scrambling

We report the results from three cross-modal lexical decision experiments investigating antecedent priming effects in Japanese. In the first two experiments we examined antecedent reactivation at the preverbal trace position in long-distance scrambling sentences. We found an interaction between the participants' working memory (WM) span and antecedent priming. For the high span group, the magnitude of antecedent priming at the trace position was significantly larger than at the earlier control position; for the low span group, on the other hand, there was no such difference. In a third experiment, we examined whether similar reactivation effects could be observed for argument expressions that are not base-generated adjacent to the verb. Contrary to scrambled objects, subject noun phrases (NPs) in canonically ordered sentences were not reactivated at the preverbal test position in either of the two participant groups. We argue that the priming effect observed in the high span group supports a trace-based account of long-distance scrambling. The degree of complexity of the experimental sentences was such that they exceeded the memory span of the low span group. We conclude that argument traces access their antecedents irrespective of the position of their subcategorizers.     

Mood and the subjective risk of future events

Abstract

In three experiments we investigated the relationship between mood and risk estimation. In Experiment 1, mood was changed by having subjects imagine a series of either positive or negative events. Judgements of future event likelihoods were biased in a global fashion; i.e. events which were used in the mood manipulation did not change to a greater degree than similarly valenced events not used in the manipulation. The results of Experiments 2 and 3 suggest that the failure to find specific biasing for those events used to change mood state is most likely due to interference resulting from presentation of multiple stimuli. It is concluded that events which influence mood can have both global and specific priming effects, consistent with expectations based on an activation/availability model.     

Time course of free-choice priming effects explained by a simple accumulator model

Unconscious visual stimuli can be processed by human observers and modulate their behavior. This has been shown for masked prime stimuli that influence motor responses to subsequent target stimuli. Beyond this, masked stimuli can also affect participants' behavior when they are free to choose one of two response alternatives. This finding demonstrates that an apparently free-choice between alternative behaviors can be subject to influences that are outside of awareness. We report three experiments which exhibit that the temporal dynamic of free-choice priming effects corresponds to that of forced-choice priming effects. Forced-choice priming effects were relatively robust against variations of prime stimuli but sensitive to physical features of target stimuli. Free-choice priming effects, in contrast, depended largely on the stimulus-response compatibility of the prime. A simple accumulator model which accounts for forced-choice response priming can also explain free-choice priming effects by the assumption that unconscious stimuli can initiate motor responses when participants are engaged in a speeded choice-reaction time task. According to our analyses free-choice priming results from a response selection mechanism which integrates conscious and unconscious information from external, stimulus driven sources and also from internal sources.     

自我概念对自传体记忆的影响：来自藏族和汉族青少年的比较研究证据

共有136名藏族和139名汉族青少年参与本实验。研究使用指导语启动方法控制自我概念,把被试随机分到独立取向、互依取向和控制组。之后使用线索词技术,对自传体记忆进行测量,考察自我概念启动对自传体记忆的影响。结果表明,自我概念启动对藏族和汉族青少年的自传体记忆内容描述的自主取向产生了启动效应。自我概念启动对于藏族被试自传体记忆社会事件报告的影响较弱。藏族青少年的自传体记忆与自我概念存在一定程度的分离现象,其自传体记忆的社会性可能更多受到个体的文化建构影响,一定意义上表明自我概念和自传体记忆的联系具有文化差异性。     

Differential Conditioning Based on a Difference in the Predictability of Reinforcement

A Pavlovian procedure containing a set of several alternative reliable trial stimuli and a set of several alternative unreliable trial stimuli was used to determine if reliability of outcome, per se, would differentially condition additional trial stimuli that either preceded or followed those original trial stimuli in a serial conditioning paradigm. The reinforcing effectiveness of the antecedent stimuli themselves was later tested in a higher-order conditioning design. It was found that different rates could be established to the different antecedent stimuli in the absence of a difference in the probability of reinforcement. Further, stimuli paired with those antecedent stimuli in the higher-order conditioning test also exhibited a difference in rate. It was concluded that a combination of a stimulus that is always followed by food and another that is never followed by food are, in net, a more effective reinforcer than a common stimulus that has the same overall probability of reinforcement but which is followed by both outcomes.     

Memory accessibility, mood regulation, and dysphoria: difficulties in repairing sad mood with happy memories?

Recent studies have suggested that mood-incongruency effects are due to mood-regulatory processes, in which people retrieve positive memories to repair negative moods. In Study 1, the authors investigated whether dysphoria influences the accessibility of autobiographical memories following a positive or a negative mood induction combined with subsequent rumination or distraction. The results showed a mood-repair effect for nondysphoric but not for dysphoric participants following rumination. In Study 2, participants were asked to either distract themselves or to recall positive autobiographical memories after a negative mood induction. Whereas nondysphoric participants' mood improved under both conditions, dysphoric participants' mood improved only after distraction. These results suggest that dysphoria is associated with a reduced ability to use mood-incongruent recall to repair sad moods.     

Examining the time course of indexical specificity effects in spoken word recognition

Variability in talker identity and speaking rate, commonly referred to as indexical variation, has demonstrable effects on the speed and accuracy of spoken word recognition. The present study examines the time course of indexical specificity effects to evaluate the hypothesis that such effects occur relatively late in the perceptual processing of spoken words. In 3 long-term repetition priming experiments, the authors examined reaction times to targets that were primed by stimuli that matched or mismatched on the indexical variable of interest (either talker identity or speaking rate). Each experiment was designed to manipulate the speed with which participants processed the stimuli. The results demonstrate that indexical variability affects participants' perception of spoken words only when processing is relatively slow and effortful.     

Auditory,visual, and cross-modal negative priming

Auditory, visual, and cross-modal negative priming was investigated using a task in which participants judged whether stimuli were animals or musical instruments. Negative priming was observed, but only if the attended and the ignored primes evoked different responses. This pattern—negative priming after conflict, but not after nonconflict, primes—was demonstrated with visual stimuli and replicated with auditory stimuli, as well as across modalities, both auditory to visual and visual to auditory. Implications for theories of negative priming are discussed.     

Linking automatic evaluation to mood and information processing style: consequences for experienced affect, impression formation, and stereotyping

According to the feelings-as-information account, a person's mood state signals to him or her the valence of the current environment (N. Schwarz & G. Clore, 1983). However, the ways in which the environment automatically influences mood in the first place remain to be explored. The authors propose that one mechanism by which the environment influences affect is automatic evaluation, the nonconscious evaluation of environmental stimuli as good or bad. A first experiment demonstrated that repeated brief exposure to positive or negative stimuli (which leads to automatic evaluation) induces a corresponding mood in participants. In 3 additional studies, the authors showed that automatic evaluation affects information processing style. Experiment 4 showed that participants' mood mediates the effect of valenced brief primes on information processing.     

On the experience of self-relevant feedback: How self-concept organization influences affective responses and self-evaluations

We evaluated how self-concepts are represented in memory, testing predictions about how self-relevant feedback influences mood and self-evaluation. Specifically, we view the self as comprised of multiple self-aspects (e.g., daughter, sorority sister), each associated with specific attributes (e.g., shy, philanthropy). Study 1 showed that priming a self-aspect increased the accessibility of attributes idiosyncratically associated with the activated self-aspect. In Studies 2 and 3, positive or negative self-relevant feedback was provided to observe how affect and self-evaluations are mediated by self-concept representation. Study 2 demonstrated that changes in mood were accounted for by how feedback impacted evaluations of the currently activated self-aspect. Moreover, evaluations of other self-aspects shifted as they shared more attributes with the self-aspect implicated by feedback. In Study 3, feedback about an attribute also influenced affect, with stronger mood change revealed for attributes associated with a greater proportion of self-aspects. This work demonstrates that affective experiences resulting from self-relevant feedback are not determined by one’s self-concept representation in its entirety, but rather, by the impact of that feedback on activated self-aspects.     

Physically disabled students and achievement orientation: Self-concept,curriculum track,and career aspirations

Little research has been done on the vocational mobility of physically disabled students (Overs, R. In J. S. Picou and R. E. Campbell (Eds.), Career behavior of special groups. Columbus, Ohio: Charles E. Merrill, pp. 177–198). A subset of data from a larger investigation on the achievement processes of youth was analyzed in two phases to describe disabled and nondisabled tenth-grade students on certain sociodemographic variables, high school curriculum track assignment, self-concept dimensions, and educational and occupational aspirations. Additionally, a process model specifying the presence or absence of physical handicaps as an ascribed status was analyzed using path analysis. Results suggest that students who report themselves as being physically disabled are not from specific social origins or differentially allocated to curriculum tracks; more importantly, they do not hold different physical or social self-conceptions or career aspirations. The multivariate analysis shows that disabled status is a significant antecedent only to academic self-concept, having a moderate, positive effect. This finding was interpreted as being a possible “overcompensation” in one particular field when there is a weakness in another. The lack of expected differences in other variables is also discussed.     

判断框架对时序知觉位置启动效应的影响

研究采用包含两种判断框架（判断刺激出现的先后次序）的时序判断任务探讨了决策偏向对时序知觉位置启动效应的影响。实验结果表明,时序知觉中存在着位置启动效应,而且在两个靶刺激出现时间间隔不同时,被试在“哪个靶刺激先出现”和“哪个靶刺激后出现”两种判断框架下的正确率存在显著差异,但在两个靶刺激同时出现时并没有出现显著的判断框架效应。因此,本研究推测时序知觉位置启动效应的作用机制不仅包括知觉增强加工过程,而且也与认知决策有关,这为反应偏向理论提供了新的支持证据。     

Attentional selection is biased toward mood-congruent stimuli

One can exert significant volitional control over the attentional filter so that stimuli that are consistent with one's explicit goals are more likely to receive attention and become part of one's conscious experience. Here we pair a mood induction procedure with an inattentional blindness task to show that one's current mood has a similar influence on attention. A positive, negative, or neutral mood manipulation was followed by an attentionally demanding multiple-object tracking task. During the tracking task, participants were more likely to notice an unexpected face when its emotional expression was congruent with participants' mood. This was particularly true for the frowning face, which was detected almost exclusively by participants in the sad mood induction condition. This attentional bias toward mood-congruent stimuli provides evidence that one's temporary mood can influence the attentional filter, thereby affecting the information that one extracts from, and how one experiences the world.     

Preferential processing of self-relevant stimuli occurs mainly at the perceptual and conscious stages of information processing

Self-related stimuli, such as one’s own name or face, are processed faster and more accurately than other types of stimuli. However, what remains unknown is at which stage of the information processing hierarchy this preferential processing occurs. Our first aim was to determine whether preferential self-processing involves mainly perceptual stages or also post-perceptual stages. We found that self-related priming was stronger than other-related priming only because of perceptual prime-target congruency. Our second aim was to dissociate the role of conscious and unconscious factors in preferential self-processing. To this end, we compared the “self” and “other” conditions in trials where primes were masked or unmasked. In two separate experiments, we found that self-related priming was stronger than other-related priming but only in the unmasked trials. Together, our results suggest that preferential access to the self-concept occurs mainly at the perceptual and conscious stages of the stimulus processing hierarchy.     

保留的跨通道启动与老化：对于近期观点的总结

通道内重复启动的研究提示老年人内隐记忆未受损, 这不只体现在视觉通道上还包括其他感觉通道(例如触觉、听觉和嗅觉)。然而很少有研究考察启动任务是否具有通道特异性。在以年轻人为被试的研究中发现跨通道迁移(视觉到触觉和触觉到视觉)和通道内迁移(视觉到视觉, 触觉到触觉)具有相似性。一项最近的研究进一步探索老年人在跨通道启动任务上是否受损。结果显示视觉和触觉间的跨通道启动在年轻被试和老年被试上都是保留的且具有对称性。并且, 对于自然声响、图片的通道内和跨通道启动任务随着年老化发展仍旧保留。这些行为结果和其它最近神经科学结果显示跨通道启动发生于枕叶后纹状皮层区, 而这一区域在老年人中未损坏。这一领域未来的研究方向包括利用不同知觉通道间、利用熟悉的和新异的刺激并结合行为的和脑成像的方法, 通过设计完善的跨通道启动来研究正常老人与阿尔兹海默病人, 还包括将设计得完善的启动任务包括在用于改善老年人记忆功能的项目中。     

Evidence of vocal and manual event files in auditory negative priming

Negative priming with auditory as well as with visual stimuli has been shown to involve the retrieval of prime response information as evidenced by an increase of prime response errors to the probes of ignored repetition trials compared to control trials. We investigated whether prime response retrieval processes were also present for response modalities other than manual responding. In an auditory four alternative forced choice task participants either vocally or manually identified a target sound while ignoring a distractor sound. Negative priming was of equal size in both response modalities. What is more, for both response modalities, there was evidence of increased prime response errors in ignored repetition trials compared to control trials. The findings suggest that retrieval of event files of the prime episode including prime response information is a general mechanism underlying the negative priming phenomenon irrespective of stimulus or response modality.     

The "second skin": perceptions of disturbed and nondisturbed early adolescents on clothing, self-concept, and body image

The purpose of this investigation was to determine if there were differences between regular education and emotionally disturbed early adolescents with respect to self-concept, body image, and selected uses of clothing. A questionnaire was administered to 74 regular education students from three middle schools. An additional 27 students labeled emotionally disturbed were surveyed from one of the schools. The questionnaire contained existing measures of self-concept and body cathexis and a revised clothing scale developed by the authors. Analysis of the data using t tests revealed significant differences between the groups with regard to self-concept and body image. In both cases, regular education students perceived themselves more positively than did those labeled emotionally disturbed. Factor analysis of the clothing-use measure gave rise to five distinct factors, one of which revealed a significant difference between the groups when analyzed by t tests. This factor, "dependence," examined the emotional effects of the use of clothing on individuals, such as the ability to influence mood. The emotionally disturbed students were less likely to use clothing to influence mood than were the regular education students. The results of this investigation lend further credence to the importance of self-concept in the education curriculum, and imply that the usual aspects of the curriculum that deal with self-concept may be served better by helping the individual become more realistic and self-accepting. The use of clothing as a tool to enhance self-concept merits further investigation.     

Decision mechanisms underlying mood-congruent emotional classification

There is great interest in understanding whether and how mood influences affective processing. Results in the literature have been mixed: some studies show mood-congruent processing but others do not. One limitation of previous work is that decision components for affective processing and responses biases are not dissociated. The present study explored the roles of affective processing and response biases using a drift-diffusion model (DDM) of simple choice. In two experiments, participants decided if words were emotionally positive or negative while listening to music that induced positive or negative mood. The behavioural results showed weak, inconsistent mood-congruency effects. In contrast, the DDM showed consistent effects that were selectively driven by an a-priori bias in response expectation, suggesting that music-induced mood influences expectations about the emotionality of upcoming stimuli, but not the emotionality of the stimuli themselves. Implications for future studies of emotional classification and mood are subsequently discussed.
