本文综述并探讨了自上而下因素的调节对启动过程的影响作用。自上而下因素的调节作用是指根据外界不断更新的对行为的要求, 大脑皮层的活动被设定于某种特殊的工作模式中。启动过程是指先前出现的启动刺激对随后目标刺激加工的易化和抑制, 是自动加工过程的体现。近年来, 部分研究认为启动范式引发的自动加工过程(包括知觉加工、语义加工和反应过程)可受到与注意、任务相关的自上而下因素的调节, 例如, 任务指导语的作用、对注意范围的设定等等。本文对此领域的研究及年龄因素进行了总结、分析和展望。启动效应可受到自上而下的注意、目的、任务要求等因素的调节, 且存在年龄因素的影响。  相似文献

The human visual system is extremely sensitive to the directions of the gazes of others. However, the mechanism underlying gaze direction perception has yet to be clarified. The primary aim of the present study is to investigate whether the relational property between the local eye region and other facial regions serves as the primary visual system cue in detecting a direct gaze. Our results showed that search efficiency was determined primarily by the gaze direction indicated by the relational property regardless of the direction indicated by the local feature information of the eye region; this was true even when the gaze directions indicated by these two types of information were conflicting. These results bolster the hypothesis that the human visual system primarily accesses socially meaningful information in searching for a deviant gaze.  相似文献

A novel explanation of belief bias in relational reasoning is presented based on the role of working memory and retrieval in deductive reasoning, and the influence of prior knowledge on this process. It is proposed that belief bias is caused by the believability of a conclusion in working memory which influences its activation level, determining its likelihood of retrieval and therefore its effect on the reasoning process. This theory explores two main influences of belief on the activation levels of these conclusions. First, believable conclusions have higher activation levels and so are more likely to be recalled during the evaluation of reasoning problems than unbelievable conclusions, and therefore, they have a greater influence on the reasoning process. Secondly, prior beliefs about the conclusion have a base level of activation and may be retrieved when logically irrelevant, influencing the evaluation of the problem. The theory of activation and memory is derived from the Atomic Components of Thought‐Rational (ACT‐R) cognitive architecture and so this account is formalized in an ACT‐R cognitive model. Two experiments were conducted to test predictions of this model. Experiment 1 tested strength of belief and Experiment 2 tested the impact of a concurrent working memory load. Both of these manipulations increased the main effect of belief overall and in particular raised belief‐based responding in indeterminately invalid problems. These effects support the idea that the activation level of conclusions formed during reasoning influences belief bias. This theory adds to current explanations of belief bias by providing a detailed specification of the role of working memory and how it is influenced by prior knowledge.  相似文献

Syntactic priming in language production is the increased likelihood of using a recently encountered syntactic structure. In this paper, we examine two theories of why speakers can be primed: error‐driven learning accounts (Bock, Dell, Chang, & Onishi, 2007; Chang, Dell, & Bock, 2006) and activation‐based accounts (Pickering & Branigan, 1999; Reitter, Keller, & Moore, 2011). Both theories predict that speakers should be primed by the syntactic choices of others, but only activation‐based accounts predict that speakers should be able to prime themselves. Here we test whether speakers can be primed by their own productions in three behavioral experiments and find evidence of structural persistence following both comprehension and speakers’ own productions. We also find that comprehension‐based priming effects are larger for rarer syntactic structures than for more common ones, which is most consistent with error‐driven accounts. Because neither error‐driven accounts nor activation‐based accounts fully explain the data, we propose a hybrid model.  相似文献

Neuroticism has been hypothesized to systematically relate to semantic memory networks favoring negative affect, but no studies using affective priming tasks have established this link. The present two studies, involving 145 undergraduate participants, sought to provide initial evidence along these lines. Study 1 used a task in which participants were asked to judge their emotions in the past, whereas Study 2 used a perceptual identification task in which participants merely had to identify the word in question. In both studies, neuroticism was positively correlated with negative affective priming, but not positive affective priming. The studies suggest that neuroticism systematically relates to the inter-connectivity of negative affect with semantic memory systems, whether involving the self-concept (Study 1) or not (Study 2). These results are novel and important in understanding individual differences in neuroticism and their affective processing correlates.  相似文献

Dehaene等(1998)和Greenwald等(1996)的研究通过在方法上的完善, 为阈下知觉的存在提供了确凿的证据。但是阈下知觉可以达到什么样的深度这一问题尚仍然存在争议, 有研究者认为阈下知觉可以达到语义加工的水平, 而有的研究者认为阈下知觉只是对刺激视觉特征的一种浅层加工, 并形成了一些非语义加工的假说。在以往研究的基础上, 本研究通过完善实验范式, 分别采用图片、字词作为实验材料对阈下知觉的深度和影响因素进行探讨。实验1和实验2立据于阈下非语义加工的各种理论, 为阈下语义加工的存在提供了证据。同时实验2表明, 阈下知觉达到的水平取决于靶子集的大小, 更确切的说取决于被试对靶刺激进行了何种水平的加工。  相似文献

Palmer has recently criticized Relational Frame Theory (RFT) on the grounds that it has developed data in search of a principle. In this reply, we show that he has done so by attacking fundamental concepts within behavior analysis itself, including the functional nature of an operant and contingencies of reinforcement as a behavioral process. His claim that RFT appeals to new behavioral principles to explain the development of relational operants is shown to be incorrect: As with any operant, RFT appeals to a history of contacted consistencies in contingencies across multiple ex-emplars to explain them. New principles only emerge later as a logically necessary extension of such operants if they exist--a view that Palmer failed to address or appreciate. Palmer's desire to see the use of methods other than matching-to-sample is proper but already largely satisfied in the empirical literature on RFT. We show Palmer's defense of Skinner's definition of verbal behavior to be illogical and unresponsive to the empirical challenge behavior analysis faces. Palmer's alternative common sense mediational associationistic account is another in more than a century of such accounts, all of which have failed empirically. At its root, Palmer's criticism is based on a mechanistic philosophy that is hostile to a traditional functional behavior analytic approach.  相似文献

具身认知受到越来越多关注, 社会心理学家认为社会关系与个体水平的认知一样都包含了具身方面, 这一问题最直接的解释框架是关系模式理论(Smith, 2008)。Fiske认为人类有4种基本关系类型:公共共享(CS)、等级排序(AR)、平等匹配(EM)和市场定价(MP), 前三种都是具身的, 与不同的具身线索存在联系, 也得到了实证支持。当前具身社会关系研究存在不足, 例如解释范围有限、缺乏整合和深入研究等。未来可以从婴幼儿的发展性研究等入手。  相似文献

启动和探测刺激相同试次低比例时可出现类似负启动的抑制现象。本研究采用不同于以往研究的单一探测范式,并操纵相关项(启动与探测词语义相关)的比例及刺激集的大小研究这一抑制机制的特点。实验一在低比例时发现了显著的负启动效应。实验二在低比例时,发现小的刺激集能诱发负启动,而大的则不能。表明在单一探测范式中启动与探测相关试次的低比例确实能诱发抑制控制,该抑制控制由忽视策略所致,并受刺激集大小的影响,支持了干扰项的凸显能够诱发强抑制的观点。  相似文献

Although structural priming has been considered to be an independent cognitive process, recent evidence suggests that structural priming is modulated by sociocognitive factors such as social perception; speakers are more likely to mimic the sentence structure of a socially desirable interlocutor than the structure of a less desirable interlocutor. This study aims to further address the role of sociocognitive factors in language use by investigating how individual differences in social perception and tendency to align with others (i.e., social monitoring) modulate same‐verb structural priming. In particular, we investigate how likely students are to repeat a sentence structure of a teacher depending on their perception of the teacher and their social monitoring tendency. Our results demonstrate that students’ tendency to imitate a sentence structure of the teacher is positively influenced by their perception of the teacher but negatively by social monitoring. We suggest that the effects may be accounted for in terms of their influence on attention and memory encoding.  相似文献

In this article, we assert that relationships and networks are of paramount importance for understanding and improving settings, neighborhoods, communities, and larger social systems. Despite previous acknowledgements of their relevance, relational and social network perspectives and analyses remain underrepresented in community psychological research and action. Here, we claim that network and relational perspectives can provide conceptual and empirical ‘links’ between levels of analysis, more fully reflecting a transactional view. We also describe some of the sophisticated methodologies that can be employed in empirical studies drawing on these perspectives. Additionally, we contend that core concepts in community psychology such as health promotion, empowerment, coalition building, and dissemination and implementation can be better understood when employing relational and network perspectives. As an introduction to this special issue of American Journal of Community Psychology, we draw out themes and key points from the articles in the issue, and offer recommendations for future advancement of these perspectives in the field.  相似文献

关于两位数的加工方式有整体加工说和局部加工说,实验证据主要来自数字数量控制/主动加工任务。本研究主要考察在数字数量自动加工任务中两位数的加工方式。实验一要求被试完成数量大小比较和物理大小比较两个任务,实验二只要求被试完成物理大小比较任务。结果是在数量比较任务和物理比较任务中都存在显著的个位十位一致性效应和数量物理一致性效应,这表明在两位数的数量主动和自动加工任务中均存在整体加工和局部加工两种方式。  相似文献

Relational reasoning (A > B, B > C, therefore A > C) shares a number of similarities with numerical cognition, including a common behavioural signature, the symbolic distance effect. Just as reaction times for evaluating relational conclusions decrease as the distance between two ordered objects increases, people need less time to compare two numbers when they are distant (e.g., 2 and 8) than when they are close (e.g., 3 and 4). Given that some remain doubtful about such analogical representations in relational reasoning, we determine whether numerical cognition and relational reasoning have other overlapping behavioural effects. Here, using relational reasoning problems that require the alignment of six items, we provide evidence showing that the subjects' linear mental representation affects motor performance when evaluating conclusions. Items accessible from the left part of a linear representation are evaluated faster when the response is made by the left, rather than the right, hand and the reverse is observed for items accessible from the right part of the linear representation. This effect, observed with the prepositions to the left of and to the right of as well as with above and below, is analogous to the SNARC (Spatial Numerical Association of Response Codes) effect, which is characterized by an interaction between magnitude of numbers and side of response.  相似文献

Funeral rituals perform important social functions for families and communities, but little is known about the motives of people planning funerals. Using mixed methods, we examine funeral planning as end-of-life relational spending. We identify how relational motives drive and manifest in funeral planning, even when the primary recipient of goods and services is dead. Qualitative interviews with consumers who had planned pre-COVID funerals (N = 15) reveal a caring orientation drives funeral decision-making for loved ones and for self-planned funerals. Caring practices manifest in three forms: (a) balancing preferences between the planner, deceased, and surviving family; (b) making personal sacrifices; and (c) spending amount (Study 1). Archival funeral contract data (N = 385) reveal supporting quantitative evidence of caring-driven funeral spending. Planners spend more on funerals for others and underspend on their own funerals (Study 2). Preregistered experiments (N = 1,906) addressing selection bias replicate these results and find generalization across different funding sources (planner-funded, other-funded, and insurance; Studies 3A–3C). The findings elucidate a ubiquitous, emotional, and financially consequential decision process at the end of life.  相似文献

Neuroimaging of Priming: New Perspectives on Implicit and Explicit Memory   总被引:2,自引:0,他引:2  
Priming refers to a change in the ability to identify or produce an item as a consequence of a specific prior encounter. Priming has been studied extensively in cognitive studies of healthy volunteers, neuropsychological investigations of brain-damaged patients, and, more recently, studies using modern functional neuroimaging techniques such as positron emission tomography and functional magnetic resonance imaging. We review recent neuroimaging studies that have converged upon the conclusion that priming is reliably accompanied by decreased activity in a variety of brain regions. The establishment of this cortical signature of priming is beginning to generate new hypotheses concerning the relation between priming and explicit retrieval, which we illustrate by considering recent experiments on within- and cross-modality priming.  相似文献
