Event-related potentials as brain correlates of item specific proportion congruent effects

The item-specific proportion congruency (ISPC) effect is consistent with the idea that control processes can be applied rapidly in accord with previously experienced conflict for a particular category. An alternative account of this effect is that it reflects item-specific learning processes unrelated to control at the level of the category. The accounts predict the same behaviour but differ in terms of electrophysiological predictions. Two experiments examined the ISPC effect with a particular focus on neural correlates that might reveal whether, and how early in processing, high and low proportion congruent items are treated as distinct classes of stimuli. For both tasks, the proportion congruency category was distinguished prior to the congruence of the specific stimulus, as early as 100 ms post-stimulus onset for the global/local identification task (Experiment 1) and 150 ms for the Stroop task (Experiment 2). The results support an on-line control account of ISPC effects.     

不同情绪状态下自动表达抑制对情绪及表情知觉敏感性的影响

以103名大学生为对象,在正性、负性两种情绪状态下,用句子整理任务引发被试抑制情绪或表达情绪两种情绪调节方式,采用信号检测论测得正、负性表情的表情知觉敏感性。结果表明：（1）表情知觉敏感性存在情绪一致性效应,在负性情绪状态下,人们对负性表情更敏感,差异显著（p=0.002）;在正性情绪状态下,人们对正性表情更敏感,虽然只是边缘显著（p=0.700）。（2）自动抑制情绪会降低人们的情绪体验,并且会影响表情知觉敏感性的情绪一致性效应。在自动抑制启动的状态下,人们对正、负性表情都不太敏感。     

Justice sensitivity and the processing of justice‐related information

We investigated how Justice Sensitivity (JS) shapes the processing of justice‐related information. We proposed that due to frequently perceiving and ruminating about injustices, persons high in JS develop highly accessible and differentiated injustice concepts that shape attention, interpretation and memory for justice‐related information. Three studies provided evidence for these assumptions. After witnessing injustice, persons high in JS attended more strongly to unjust stimuli than to negative control stimuli (Study1) and interpreted an ambiguous situation as less just than persons low in JS (Study2). Finally, they displayed a memory advantage for unjust information (Study3). Results suggest that JS involves the availability and accessibility of injustice concepts as parameters of cognitive functioning and offer explanations for effects of JS on justice‐related behaviour.

Mood-congruent bias and attention shifts in the different episodes of bipolar disorder

An “affective” go/no-go task was used in the different episodes of bipolar patients (euthymic, depressed, and manic) to examine (1) the presence of a mood-congruent attentional bias; and (2) the patients' ability to inhibit and invert associations between stimuli and responses through blocks. A group of healthy individuals served as controls. Results revealed a mood-congruent attentional bias: patients in the manic episode processed positive information faster, whereas those in the depressive episode processed negative information faster. In contrast, neither euthymic patients nor healthy individuals showed any mood-congruent biases. Furthermore, there was a shift cost across blocks for healthy individuals, but not for the patients. This may reflect a general impairment at selecting relevant information (e.g., in terms of disability to inhibit and invert associations between stimuli and responses) in bipolar participants, regardless of their episode. This state/trait dissociation in an episodic and chronic disorder such as bipolar disorder is important for its appropriate characterisation.     

Synchronicity and the meaning-making psyche

This paper contrasts Jung's account of synchronicity as evidence of an objective principle of meaning in Nature with a view that emphasizes human meaning-making. All synchronicities generate indicative signs but only where this becomes a 'living symbol' of a transcendent intentionality at work in a living universe does synchronicity generate the kind of symbolic meaning that led Jung to posit the existence of a Universal Mind. This is regarded as a form of personal, experiential knowledge belonging to the 'imaginal world of meaning' characteristic of the 'primordial mind', as opposed to the 'rational world of knowledge' in which Jung attempted to present his experiences as if they were empirically and publicly verifiable. Whereas rational knowledge depends on a form of meaning in which causal chains and logical links are paramount, imaginal meaning is generated by forms of congruent correspondence-a feature that synchronicity shares with metaphor and symbol-and the creation of narratives by means of retroactive organization of its constituent elements.     

List-level transfer effects in temporal learning: Further complications for the list-level proportion congruent effect

Congruency effects are larger when most trials are congruent relative to incongruent. According to the conflict adaptation account, this proportion congruent effect is due to the decreased attention to words when most of the trials are conflicting. This paper extends on previous work arguing that list-level (contingency-unbiased) proportion congruent effects might be explainable by temporal learning biases. That is, congruency effects are larger in an easier task (i.e., mostly congruent) due to the faster pace of the task. Two non-conflict analogues of the proportion congruent effect are presented, one with a contrast manipulation and another with a contingency manipulation. Critically, both experiments control for potential item-specific temporal learning biases by intermixing biased context and unbiased transfer items. Results show a proportion congruent-like interaction for both item types, supporting the notion of task-wide temporal learning as an explanation for list-level proportion congruency effects. Distributional analyses lend further credence to the temporal learning account by showing that proportion congruent and proportion congruent-like effects are localised in the fastest and intermediate responses.     

When proportion consensus scoring works

Most objectively scored tests use items with easily identifiable correct answers. When such veridical scoring keys cannot be constructed, researchers sometimes use proportion consensus scoring (PCS) to identify the best answers. To determine if PCS identifies the best answers, we scored a test using both PCS and veridical scoring. Among 353 undergraduates, regular PCS, two-stage PCS, and expert PCS all had high correlations for easy items, but no PCS methods had high correlations for difficult items. Thus, PCS cannot reliability identify the best answers to individual items. However, PCS worked well for total scores. For easy items, total scores had correlations above .99 for all PCS methods. For difficult items, expert and two-stage PCS had correlations of .92 and .82 for the 60-item test. Thus, expert and two-stage PCS can be justified (even for difficult items) if the scoring key is based upon people who truly possess some degree of expertise and if scores are summed over many items.     

领导-团队投入匹配对团队绩效的影响：团队满意度氛围的作用

基于领导-团队匹配的视角,研究以133名领导和645名成员的团队配对数据,采用二次多项式回归与响应面分析对领导工作投入与团队投入氛围的一致性匹配和不一致性匹配,以及团队满意度氛围如何影响团队绩效进行了探讨。结果发现：领导工作投入与团队投入氛围一致与不一致相比,团队绩效较好;并且一致性匹配具有加强效应,即当领导工作投入与团队投入氛围一致时,团队绩效随着双方投入的增加而提高;同时,团队满意度氛围在领导-团队投入的一致性匹配与团队绩效的线性关系中起到部分中介作用。     

Differential validity of the Gottschalk-Gleser Anxiety Scales: is gender a moderator variable?

It can be hypothesized that affects like anxiety can be measured by content analysis of speech due to the phenomenon of mood congruent memory, which is found predominantly in females. To assess the effect of gender on the validity of the Gottschalk-Gleser Anxiety Scales, the standard procedure for obtaining verbal samples was followed and self-report measurements of comparable emotional constructs were applied concurrently. Measures of state and trait emotions were administered to 25 female and 25 male university students. In the female group 18 significant convergent validity coefficients were found. For males, content analytic anxiety scores showed four significant correlations with concurrent self-report scales. These results suggest that content analytic anxiety scores from female subjects may allow a more accurate prediction of state and trait emotions than anxiety scores from male subjects. Thus, gender might have a differential effect on the validity of the Gottschalk-Gleser Anxiety Scales.
