Distinct conflict resolution deficits related to different facets of Schizophrenia

An important issue in understanding the nature of conflict processing is whether it is a unitary or multidimensional construct. One way to examine this is to study whether people with impaired conflict processing exhibit a general pattern of deficits or whether they exhibit impairments in distinct aspects of conflict processing. One group who might exhibit conflict deficits are people with schizophrenia. Schizophrenia is a heterogeneous disorder, with one way to break down the heterogeneity of schizophrenia is to examine specific symptoms. Previous research has found that specific symptoms of schizophrenia are associated with specific deficits in conflict processing. In particular, disorganization is associated with increased response conflict, alogia is associated with increased retrieval conflict, and anhedonia is associated with increased emotional conflict. Moreover, there is evidence that different types of conflict processing are unassociated with each other. This evidence suggests that conflict processing is a multidimensional construct and that different aspects of schizophrenia are associated with impairments in processing different types of conflict.     

动力学与吸引子理论在冲突研究中的应用

用动力学的观点来看待冲突是近年来关于冲突研究的一个新发展。与传统的研究概念和方法不同的是,动力学的观点将冲突及与冲突相关的过程作为一个复杂系统,冲突各方的思想、情感和行为的相互关系构成了冲突内在的动力学机制。系统内各要素的相互关系可以用吸引子来反映,冲突的发展和结束取决于引发冲突的吸引子的性质。所谓成功的干预则意味着冲突各方形成了新的心理和行为模式和不同于以往的心理和社会环境。     

Potential influence structures as sources of interpersonal conflict in groups and organizations

It is argued that conflict in organizations can be interpreted, in many cases, as conflict over who is to exert influence, and that this conflict, in turn, is caused by structural incongruencies in the distribution of potential influence in groups and organizations. Potential influence is described in terms of the structural relations defined by Structural Role Theory. At the psychological level, conflict is explained as a result of incompatible expectations among people about their relative influence, their desire to protect valued roles, and to maintain a sense of freedom. The implications of the present hypothesis for specifying the range of conflict situations, the type of conflict behavior, and conflict management are explored.     

推理判断中偏差反应的加工机制：冲突探查失败，还是抑制失败？

通过控制自变量一致性（冲突、非冲突）与问题类型（基础比率问题、合取问题）,对推理判断中偏差反应的加工机制：冲突探查失败,还是抑制失败,进行验证。反应时、反应自信度的结果支持抑制失败说,被试对冲突的探查是成功的,偏差反应的产生是没能抑制占主导的直觉。而冲突探查大小（Conflict detection size）的结果表明冲突探查存在个体差异,有些被试对两种加工间的冲突探查过程完美无暇(Flawless detection),有些被试的冲突探查过程松散马虎(Lax detection),而且受到问题类型的影响。     

Stimulus conflict predicts conflict adaptation in a numerical flanker task

Conflict monitoring theory states that response conflict triggers conflict adaptation, resulting in reduced congruency effects after response-incongruent trials (Botvinick, Braver, Barch, Carter, & Cohen, 2001). Verbruggen, Notebaert, Liefooghe, and Vandierendonck (2006) observed conflict adaptation after stimulus-incongruent trials without any response conflict. In this study, we further explore the hypothesis that stimulus conflict is an important trigger for conflict adaptation. We propose a measure for stimulus conflict that adequately explains the data of Verbruggen et al. and new data from a numerical flanker task. We conclude that stimulus conflict and response conflict have dissociable effects on behavior Whereas response conflict is a good predictor of response times, stimulus conflict is a better predictor of the adaptation effect.     

The neural basis of error detection: conflict monitoring and the error-related negativity

According to a recent theory, anterior cingulate cortex is sensitive to response conflict, the coactivation of mutually incompatible responses. The present research develops this theory to provide a new account of the error-related negativity (ERN), a scalp potential observed following errors. Connectionist simulations of response conflict in an attentional task demonstrated that the ERN--its timing and sensitivity to task parameters--can be explained in terms of the conflict theory. A new experiment confirmed predictions of this theory regarding the ERN and a second scalp potential, the N2, that is proposed to reflect conflict monitoring on correct response trials. Further analysis of the simulation data indicated that errors can be detected reliably on the basis of post-error conflict. It is concluded that the ERN can be explained in terms of response conflict and that monitoring for conflict may provide a simple mechanism for detecting errors.     

Upsetting the apple cart: Within-team profiles of intragroup conflict and their associations with narcissism

Different types of intragroup conflict (i.e., relationship, task, and process conflict) co-exist in team environments yet how this co-existence is expressed is poorly understood, particularly in sports teams. Further, there is a lack of knowledge surrounding the antecedents of intragroup conflict. Here, we examined the nature of conflict profiles in sports teams and investigated narcissism as an antecedent to the conflict profiles. In a large, multi-group sample (n = 1107 athletes from 109 teams), participants completed measures of intragroup conflict and narcissism. Team-level latent profile analysis of intragroup conflict variables indicated five distinct within-team conflict profiles which varied in patterns of relationship, task, and process conflict. Moreover, teams high in narcissism (both in terms of team mean and team maximum scores) were more likely to occupy dysfunctional conflict profiles, that is profiles high in all conflict types. These findings underscore the importance of considering conflict profiles within teams and provide the first evidence for narcissism as a contributing factor in the development of conflict profiles in groups.     

Domain-specific conflict adaptation without feature repetitions

An influential account of how cognitive control deals with conflicting sources of information holds that conflict is monitored by a module that automatically recruits attention to resolve the conflict. This leads to reduced effects of conflict on the subsequent trial, a phenomenon termed conflict adaptation. A prominent question is whether control processes are domain specific—that is, recruited only by the particular type of conflict they resolve. Previous studies that have examined this question used two-choice tasks in which feature repetition effects could be responsible for domain-specific adaptation effects. We report two experiments using four-choice (Experiment 1) and five-choice (Experiment 2) tasks that contain two types of irrelevant sources of potentially conflicting information: stimulus location (Simon conflict) and distractors (flanker conflict). In both experiments, we found within-type conflict adaptation for both types of conflict after eliminating trials on which stimulus features were repeated from one trial to the next. Across-type conflict adaptation, however, was not significant. Thus, conflict adaptation was due to domain-specific recruitment of cognitive control. Our results add converging evidence to the idea that multiple independent control processes are involved in reactive cognitive control, although whether control is always local remains to be determined.     

冲突水平的变化诱发冲突适应

冲突适应是重要的认知控制现象, 反映了认知控制的动态过程。然而, 目前为止对于冲突水平上的差异能否诱发冲突适应尚不清楚。本研究采用字母Flanker的变式, 通过改变目标-分心物的一致性操纵冲突水平, 探究冲突水平的变化对认知控制调整的影响。结果发现被试的反应时间随冲突水平的提高而增加; 而且先前试次的一致性影响当前试次的干扰效应, 无冲突和低冲突、无冲突和高冲突、低冲突和高冲突条件之间均出现了典型的冲突适应。本研究结果表明, 除了冲突的有无, 冲突水平的变化也能诱发冲突适应, 支持更大的冲突驱动更强的认知控制, 而且冲突诱发的认知控制的功能可能通过注意聚焦实现。这一发现为冲突监测理论的注意调节机制提供了直接的支持证据, 对于促进冲突适应的相关研究具有重要意义。     

Decision making under conflict: Decision time as a measure of conflict strength

Conflict and choice are closely related in that choice produces conflict and conflict is resolved by making a choice. Although conflict was invoked in psychological approaches to decision making early on (Lewin, 1931/1964), no generally accepted measure of conflict strength has been established (Tversky & Shafir, 1992). The present study introduces a model (multiattribute decision field theory) that predicts a decision time pattern depending on the conflict situation. In a risky decision-making experiment with multiattribute choice alternatives, decision time is investigated as a possible measure of conflict strength. It is shown that the model can be fitted to a complex choice pattern.     

The time course of attentional modulation on emotional conflict processing

Cognitive conflict resolution is critical to human survival in a rapidly changing environment. However, emotional conflict processing seems to be particularly important for human interactions. This study examined whether the time course of attentional modulation on emotional conflict processing was different from cognitive conflict processing during a flanker task. Results showed that emotional N200 and P300 effects, similar to colour conflict processing, appeared only during the relevant task. However, the emotional N200 effect preceded the colour N200 effect, indicating that emotional conflict can be identified earlier than cognitive conflict. Additionally, a significant emotional N100 effect revealed that emotional valence differences could be perceived during early processing based on rough aspects of input. The present data suggest that emotional conflict processing is modulated by top-down attention, similar to cognitive conflict processing (reflected by N200 and P300 effects). However, emotional conflict processing seems to have more time advantages during two different processing stages.     

Evidence for task-specific resolution of response conflict

When a target requires different responses to a relevant and to an irrelevant task in a task-switching paradigm, there is response conflict. This target-induced response conflict was combined with conflict caused by a subliminally presented prime presented prior to the target. We found that target-related conflict reduced prime-induced conflict effects within the same trial. However, target-related conflict modified prime-related conflict effects according to the irrelevant stimulus-response (S-R) rule, but not according to the relevant S-R rule. Moreover, trial-to-trial modulations of the target congruency effect were observed in task repetition trials, but not in task switch trials. These results indicate that conflict resolution mechanisms, at least under the present circumstances, operate in a strictly task-specific manner.     

An Ecological Critique of the Sensory Conflict Theory of Motion Sickness

In this article we present a critique of the sensory conflict theory of motion sickness. We discuss three forms of sensory conflict that are believed to exist: input conflict, output conflict, and expectancy violation. We argue that any concept of sensory conflict necessarily entails the violation of internal expectations and, hence, that the three forms of conflict are logically identical. In the motion sickness literature, it is implicit that the expected pattern is one in which the inputs of the visual, vestibular, and somatosensory systems are redundant. We argue that an expectation of redundancy cannot plausibly result from interaction with the environment. We review data indicating that nonredundant patterns of intermodal stimulation lead to adaptive changes in the control of behavior; this implies that the calculation of nauseogenic conflict must be unrelated to the control of behavior. Moreover, we argue that no single pattern of sensory stimulation, redundant or otherwise, can serve as a reliable standard or expecta- tion for the calculation of sensory conflict. We conclude that there is no principled basis on which the conflict theory can distinguish between nauseogenic and nonnauseogenic situations. It follows that the concept of sensory conflict cannot provide a theoretical explanation for the existence of motion sickness. We review data suggesting an important role for the control of behavior in the etiology of motion sickness. This suggests a new basis for understanding the phenomena of motion sickness.     

团队权力分布差异对团队冲突的影响：程序公平和合法性的作用

近年来团队权力分布差异与团队冲突间关系受到了学界较大关注, 但相关研究结果仍存在分歧。通过对70个工作团队的调查, 探讨了团队权力分布差异对团队冲突(任务冲突、关系冲突)作用的边界条件。结果发现, 程序公平调节了两者间关系：当程序公平较高时, 团队权力分布差异与任务冲突、关系冲突负相关; 当程序公平较低时, 团队权力分布差异与任务冲突、关系冲突正相关。此外, 被中介的调节模型分析显示, 团队合法性感知中介了程序公平的上述调节作用。

The impact of religious conflict within orthodox Jewish families in Israel

While prior research suggests that religion influences relationships positively, it may also be a source of conflict. This may be particularly relevant in religion-centric cultures and in families with individuating adolescent children. The current research analysed data from 789 orthodox Jewish couples residing throughout Israel and we hypothesised that religious conflict is related to lower family functioning and higher parenting stress, and that it is more frequent among couples with insecure attachment. Results of a structural equation model indicated that religious conflict was significantly associated with outcome variables within various religious subgroups, and that attachment insecurity was related to higher levels of conflict and was fully or partially mediated by religious conflict. This suggests that within the orthodox community, religious conflict is an important correlate, and perhaps cause, of family dysfunction. Future research exploring causality, cross-cultural relevance, comparability to other forms of conflict, and effective treatment appears warranted.     

负性情绪在冲突适应中的作用机制：分离与整合视角

负性情绪如何影响冲突适应一直以来受到领域内研究者们的广泛关注。根据负性情绪产生的源头(冲突外部操纵vs.冲突内部固有), 对于该问题的论述可以分别从认知与情绪的分离与整合视角展开。分离视角下, 操纵于冲突之外的负性情绪(外部负性情绪)独立于冲突加工过程, 通过情绪加工系统或个体自身的动机/唤醒水平影响冲突适应。近些年来的研究发现冲突加工自动产生负性情绪(固有负性情绪), 寓示着认知冲突与负性情绪间的内在关联, 固有负性情绪因此可被视作诱发冲突适应的另一个有效来源。整合视角下, 操纵于冲突内部的(固有)负性情绪高度整合于冲突加工过程, 其功能与冲突信息类似, 通过内在地促进目标导向行为直接诱发冲突适应。对这一主题的论述加深了我们对负性情绪如何作用于冲突适应过程的理解, 也为探索认知与情绪系统的整合过程及作用机制提供了一个全新的视角, 在此基础上, 我们也提出一些未来可行的研究方向。     

The Role of Power and Gender in Anger Responses to Sexual Jealousy

Despite a growing interest in intimate conflict, little research has examined the variables that influence anger within an interpersonal context. Using the conflict topic of sexual jealousy, male and female undergraduate students were randomly assigned to high- or low-power conditions prior to listening to an audiotaped conflict between intimates. Analysis of participants' affective responses to the conflict indicated that in spite of no initial differences in anger before hearing the conflict, there was a significant difference between power conditions in postconflict ratings: low-power participants reported more anger than did high-power participants. Similarly, women reported more anger than did men after hearing the conflict despite no preconflict differences. The results are discussed in terms of the influence of power and gender expectations on the anger dynamics of intimate conflict. Of special interest is the extent to which perceptions of power or powerlessness, ostensibly unrelated to the conflict, can shape affective reactions to conflict.
