错误后减慢理论模型述评

错误后减慢是指错误后正确反应与正确后正确反应相比反应时显著延长的现象.目前研究者已经发现错误后减慢、错误后正确率提高以及错误后干扰效应减少三种错误调控行为,其中错误后减慢是最稳定的错误后行为表现.早期研究主要从冲突监控理论、激活抑制假说、强化学习理论和失匹配理论等角度解释该现象,近年来,研究者又提出了注意朝向理论和评估适应假说.对于该领域未来的研究可以从错误类型、无意识加工、个体差异、新的分析技术的运用方面考虑,以便全面揭示错误后减慢现象的本质.     

Proactive and reactive control depends on emotional valence: a Stroop study with emotional expressions and words

We examined proactive and reactive control effects in the context of task-relevant happy, sad, and angry facial expressions on a face-word Stroop task. Participants identified the emotion expressed by a face that contained a congruent or incongruent emotional word (happy/sad/angry). Proactive control effects were measured in terms of the reduction in Stroop interference (difference between incongruent and congruent trials) as a function of previous trial emotion and previous trial congruence. Reactive control effects were measured in terms of the reduction in Stroop interference as a function of current trial emotion and previous trial congruence. Previous trial negative emotions exert greater influence on proactive control than the positive emotion. Sad faces in the previous trial resulted in greater reduction in the Stroop interference for happy faces in the current trial. However, current trial angry faces showed stronger adaptation effects compared to happy faces. Thus, both proactive and reactive control mechanisms are dependent on emotional valence of task-relevant stimuli.

Reading is believing: the truth effect and source credibility

Five experiments explored how source reliability influences people’s tendency to rate statements as more credible when they were encountered earlier (the truth effect). Undergraduates read statements from one reliable source and one unreliable source. Statements read multiple times were perceived as more valid and were more often correctly identified on a general knowledge test than statements read once or not at all. This occurred at varying retention intervals whether the statements originated from a reliable or unreliable source, when people had little memory for the statements themselves or their source, and when the discrediting information about the sources came either before or after reading the facts. While repetition aided recognition and source accuracy, both were unaffected by the reliability of the source. Consistent with the source monitoring framework, familiarity may create an illusion of truth for statements when people lack source-specifying cues, especially cues regarding the reliability of the source.     

Birth of the subject: the ethics of monitoring development programmes

NGO-based and rigorously monitored development programmes are bringing about important and positive socio-economic changes in the developing world. However, there are numerous instances of the employment of aggressive and grueling monitoring techniques which objectify the subject of development, the primary stakeholder, claiming development results as the successful achievement of goals of the donor or implementing organization. It is in this context that one can speak of an ethic of monitoring development programmes. The paper argues that such an ethic can be positively based on principles like empowering people through development work without hurting their sense of self-worth, the principle of trust and partnership and, negatively, never striving to objectify any person or people for the achievement of some objective, even if this objective is in itself honourable and desirable. The paper contends that if development is freeing the subject, the central player, to exercise their capability to live their life to the fullest, then development monitoring and development work in general has to enhance freedom, autonomy and openness.     

False recall in the Deese–Roediger–McDermott paradigm: The roles of gist and associative strength

Theories of false memories, particularly in the Deese–Roediger–McDermott (DRM) paradigm, focus on word association strength and gist. Backward associative strength (BAS) is a strong predictor of false recall in this paradigm. However, other than being defined as a measure of association between studied list words and falsely recalled nonpresented critical words, there is little understanding of this variable. In Experiment 1, we used a knowledge-type taxonomy to classify the semantic relations in DRM stimuli. These knowledge types predicted false-recall probability, as well as BAS itself, with the most important being situation features, synonyms, and taxonomic relations. In three subsequent experiments, we demonstrated that lists composed solely of situation features can elicit a gist and produce false memories, particularly when monitoring processes are made more difficult. Our results identify the semantic factors that underlie BAS and suggest how considering semantic relations leads to a better understanding of gist formation.     

Reactive and proactive control adjustments under increased depressive symptoms: Insights from the classic and emotional-face Stroop task

The current research investigated differences in reactive and proactive cognitive control as a function of depressive symptomatology. Three participant groups with varying symptom levels (Beck Depression Inventory–II, BDI–II score) completed both the classic and an emotional-face Stroop task separately under speed and accuracy instructions. All groups made equivalent speed–accuracy trade-offs independent of task, suggesting that proactive adjustments are unaffected by depressive symptoms. Additionally, groups made equivalent reactive control adjustments (Stroop effects, congruency sequence effects) in the classic Stroop task, suggesting that these reactive control adjustments are spared across a wide range of BDI–II scorers. In contrast, the high BDI–II group displayed a selective impairment in the resolution of conflict in the emotional-face Stroop task. Thus, while proactive control and many aspects of reactive control were unaffected by the level of depressive symptoms, specific impairments occurred when current task demands required the trial-to-trial regulation of emotional processing.     

Inconsistency effects in source memory and compensatory schema-consistent guessing

The attention–elaboration hypothesis of memory for schematically unexpected information predicts better source memory for unexpected than expected sources. In three source-monitoring experiments, the authors tested the occurrence of an inconsistency effect in source memory. Participants were presented with items that were schematically either very expected or very unexpected for their source. Multinomial processing tree models were used to separate source memory, item memory, and guessing bias. Results show an inconsistency effect in source memory accompanied by a compensatory schema-consistent guessing bias when expectancy strength is high, that is, when items are very expected or very unexpected for their source.     

A meta-analysis of the effects of electronic performance monitoring on work outcomes

Electronic performance monitoring (EPM), or the use of technological means to observe, record, and analyze information that directly or indirectly relates to employee job performance, is a now-ubiquitous work practice. We conducted a comprehensive meta-analysis of the effects of EPM on workers (K = 94 independent samples, N = 23,461). Results provide no evidence that EPM improves worker performance. Moreover, findings indicate that the presence of EPM is associated with increased worker stress, regardless of the characteristics of monitoring. Findings also demonstrate that organizations that monitor more transparently and less invasively can expect more positive attitudes from workers. Overall, results highlight that even as advances in technology make possible a variety of ways to monitor workers, organizations must continue to consider the psychological component of work.
