Sense of agency refers to the subjective feeling of being able to control an outcome through one’s own actions or will. Prior studies have shown that both sensory processing (e.g., comparisons between sensory feedbacks and predictions basing on one’s motor intentions) and high-level cognitive/constructive processes (e.g., inferences based on one’s performance or the consequences of one’s actions) contribute to judgments of sense of agency. However, it remains unclear how these two types of processes interact, which is important for clarifying the mechanisms underlying sense of agency. Thus, we examined whether performance-based inferences influence action-effect integration in sense of agency using a delay detection paradigm in two experiments. In both experiments, participants pressed left and right arrow keys to control the direction in which a moving dot was travelling. The dot’s response delay was manipulated randomly on 7 levels (0–480 ms) between the trials; for each trial, participants were asked to judge whether the dot response was delayed and to rate their level of agency over the dot. In Experiment 1, participants tried to direct the dot to reach a destination on the screen as quickly as possible. Furthermore, the computer assisted participants by ignoring erroneous commands for half of the trials (assisted condition), while in the other half, all of the participants’ commands were executed (self-control condition). In Experiment 2, participants directed the dot as they pleased (without a specific goal), but, in half of the trials, the computer randomly ignored 32% of their commands (disturbed condition) rather than assisted them. The results from the two experiments showed that performance enhanced action-effect integration. Specifically, when task performance was improved through the computer’s assistance in Experiment 1, delay detection was reduced in the 480-ms delay condition, despite the fact that 32% of participants’ commands were ignored. Conversely, when no feedback on task performance was given (as in Experiment 2), the participants reported greater delay when some of their commands were randomly ignored. Furthermore, the results of a logistic regression analysis showed that the threshold of delay detection was greater in the assisted condition than in the self-control condition in Experiment 1, which suggests a wider time window for action-effect integration. A multivariate analysis also revealed that assistance was related to reduced delay detection via task performance, while reduced delay detection was directly correlated with a better sense of agency. These results indicate an association between the implicit and explicit aspects of sense of agency. 相似文献

Background and objectives: Recent research has shown day-level differences in an individual’s experience of uncivil behavior; however, it is unknown if that experience follows a consistent weekly change pattern. This study extends incivility theory and research by applying latent growth curve (LGC) modeling to diary study data to understand day-to-day changes in incivility.Design: The authors took a theory-driven approach, reviewing both mood and recovery theory that would support a decrease in incivility over the working week.Methods: Diary survey methodology was used, with a morning and evening survey completed on five consecutive workdays by 171 (73% of the 235 who initially volunteered, 95% of those who completed any surveys) employees in the legal industry. LGC analysis was used to identify patterns of experienced incivility, mood (both measured after work), and recovery (assessed the following morning).Results: Regardless of job demands and gender, a weekly pattern was identified with the likelihood of experiencing incivility (coded as 0?=?none, 1?=?some) decreasing from Monday to Friday by .78 each day (p?<?.001) in a relatively linear fashion with a slope factor of .34 (SE?=?0.23; p?>?.05), indicating invariance between individuals. This weekly pattern was not explained by changes in mood or recovery.Conclusions: Results emphasize the impact of contextual factors such as time on workplace incivility and the need to consider weekly rhythms of other behaviors that are likely to affect employee well-being and productivity. Although limited to one week of data per person, the findings are likely to be relevant to studies of other forms of interpersonal mistreatment, such as social undermining and interpersonal conflict. 相似文献

The distinction between the body schema and the body image has become the stock in trade of much recent work in cognitive neuroscience and philosophy. Yet little is known about the interactions between these two types of body representations. We need to account not only for their dissociations in rare cases, but also for their convergence most of the time. Indeed in our everyday life the body we perceive does not conflict with the body we act with. Are the body image and the body schema then somehow reshaping each other or are they relatively independent and do they only happen to be congruent? On the basis of the study of bodily hallucinations, we consider which model can best account for the body schema/body image interactions. 相似文献

使用《运动想象问卷−修订版》筛选出的30名被试(男女各半), 采用功能性近红外光谱成像技术(fNIRS)监测被试在执行实际举哑铃(男生, 4磅和8磅; 女生, 2磅和4磅)任务和想象举同等重量哑铃任务时, 其大脑皮层氧合血红蛋白浓度的变化。结果发现:男女被试在运动执行与运动想象任务下都激活了主运动皮层; 且运动执行的大脑激活水平高于运动想象。在执行实际运动任务时, 运动强度显著影响大脑皮层血氧浓度的变化, 表现出左半球偏侧化优势; 在执行想象运动任务时, 运动强度没有影响大脑皮层血氧浓度的变化, 且无偏侧化现象。 相似文献

采用整群取样的方法在全国按东部、中部和西部共抽取了7所高校的1983名新生,进行了历时四个月的四次追踪测试。使用潜变量增长模型建模,分别考察了新生主观社会地位和抑郁的变化轨迹,并就两者间的变化关系进行了分析。结果发现新生入学后四个月内:(1)主观社会地位呈阶段化线性增长,其起始水平和第一阶段的增长速度存在显著个体间差异;(2)抑郁呈二次方增长,其起始水平和增长速度存在显著个体间差异;(3)入学后主观社会地位的下滑速度能有效预测新生抑郁水平的上升速度。研究基于情绪压制理论,对主观社会地位与抑郁间的变化关系进行了分析。 相似文献

采用独立记得-知道范式(IRK)和加工分离范式(PDP)探讨焦点阅读中文本表征的意识性。根据阅读材料中人物特征与其目标行为的关系,创设一致和恢复一致两种实验条件,实验1、2分别使用独立记得-知道范式,加工分离范式研究文本表征的意识性问题。研究结果发现被试在两种实验条件下的有意识加工和无意识加工指标上有显著差异,说明在焦点阅读中命题表征和情境模型的建构都是有意识的。 相似文献

卢比孔模型包括四个阶段(前决策、前行动、行动和后行动)、三种意向(目标、执行和评价)及调控机制,旨在勾画愿望如何转换为具体行动。过往的研究聚焦于心理定势和执行意向,近年则扩及于消费和健康心理学等领域中。透过对照何谓好理论的准则及检视其他动机理论的局限,卢比孔模型的优点呈现为建构上的简约,能区分动机和意志过程并体现其复杂性,且应用广泛。针对此模型的拓展,可就往昔被忽略的环节进行更细致的研究。 相似文献

In this paper I examine some presuppositions of toleration and pluralism and explore two models, viz., a deontological and a consequentialist model, respectively, which could support the view that rational agents should act in a tolerant way. Against the background which is offered by the first model, I give two arguments in favor of the view that people are better off and more rational if they act in a tolerant way. The first argument draws upon a principle of charity which is usually applied in philosophy of mind and philosophy of language, but which could, equally well, work with regard to foundational issues in ethics and philosophy of action. The second argument is built upon the epistemic principle of fallibilism and it is meant to show that acting in a tolerant way is the rational thing to do from this perspective. 相似文献
