Building on the dual-system theory of judgment, we propose an intuitive and deliberate framework for understanding the effects of preference construction in choice. We argue that while certain choice effects can be attributed primarily to rapid, unintentional, and intuitive processing, others arise from intentional and deliberate processing. We use this distinction to group choice effects previously identified in the literature, discuss evidence in support of the dual-system framework of preference construction, and propose new research directions. Since the defining property of intuitive versus deliberate mental processes is the degree to which they engage working memory, the proposed framework sheds light on how these previously identified effects will change with conditions such as the availability of cognitive resources. We conclude by calling for additional research to explore the interplay between intuitive and deliberate processing to determine which processes are implicated in generating a preference, as well as research on new moderators of choice effects based on the difference in the amount of willful information processing that underlies decision making.  相似文献

Theories of adult reasoning propose that reasoning consists of two functionally distinct systems that operate under entirely different mechanisms. This theoretical framework has been used to account for a wide range of phenomena, which now encompasses developmental research on reasoning and problem solving. We begin this review by contrasting three main dual-system theories of adult reasoning (Evans & Over, 1996; Sloman, 1996; Stanovich & West, 2000) with a well-established developmental account that also incorporates a dual-system framework (Brainerd & Reyna, 2001). We use developmental studies of the formation and application of intuitive rules in science and mathematics to evaluate the claims that these theories make. Overall, the evidence reviewed suggests that what is crucial to understanding how children reason is the saliency of the features that are presented within a task. By highlighting the importance of saliency as a way of understanding reasoning, we aim to provide clarity concerning the benefits and limitations of adopting a dual-system framework to account for evidence from developmental studies of intuitive reasoning.  相似文献

Dhar and Gorlin (2013) proposed a dual-process framework for understanding the effects of preference construction in choice. Drawing on the distinction operating principles and operating conditions, it is argued that their emphasis on cognitive elaboration fails to specify the mental operations involved in preference construction. This limitation makes their dual-process framework circular and susceptible to the criticism of single-process alternatives. The distinction between associative and propositional processes has the potential to fill this conceptual gap, thereby providing a more thorough understanding of preference construction effects in choice.  相似文献

双系统理论认为人类在推理过程中存在着两种类型的加工方式:一种为快速的、不受工作记忆资源影响的启发式加工; 一种为慢速的、受认知资源限制的分析式加工。通过对这两种加工类型互相作用方式的深入研究,目前已经形成了不同的加工模型,意图解决核心问题——推理偏差产生的原因。本研究从双系统加工模型入手,结合最新的行为、训练以及神经机制的研究,对导致推理偏差的原因究竟是冲突察觉还是冲突抑制的失败进行详细分析  相似文献

We explore the developmental paradox of false belief understanding. This paradox follows from the claim that young infants already have an understanding of false belief, despite the fact that they consistently fail the elicited-response false belief task. First, we argue that recent proposals to solve this paradox are unsatisfactory because they (i) try to give a full explanation of false belief understanding in terms of a single system, (ii) fail to provide psychological concepts that are sufficiently fine-grained to capture the cognitive requirements for the various manifestations of false belief understanding, and (iii) ignore questions about system interaction. Second, we present a dual-system solution to the developmental paradox of false belief understanding that combines a layered model of perspective taking with an inhibition-selection-representation mechanism that operates on different levels. We discuss recent experimental findings that shed light on the interaction between these two systems, and suggest a number of directions for future research.  相似文献

The purpose of this paper is to show that the standard notion of informed choice is unacceptable and must be replaced. To do so, I examine Foucault's analysis of people in contemporary society, drawing attention to the ways power relations act upon us, and to the possibility of resistance. I show how feminist moral theory can be enriched by Foucault's analysis. Applying this new understanding of people and moral theory to an analysis of informed choice, I claim that the standard notion of informed choice is unacceptable, in part because it relies on a false conception of people. Its “necessary” features—intention, understanding, and absence of controlling influences—are much more difficult, if not impossible, to obtain than proponents of the standard notion believe. I end by offering direction for creating a new, Foucault-inspired, feminist theory of informed choice.  相似文献

Are the linguistic forms that are memorized in the mental lexicon and those that are specified by the rules of grammar subserved by distinct neurocognitive systems or by a single computational system with relatively broad anatomic distribution? On a dual-system view, the productive -ed-suffixation of English regular past tense forms (e.g., look-looked) depends upon the mental grammar, whereas irregular forms (e.g., dig-dug) are retrieved from lexical memory. On a single-mechanism view, the computation of both past tense types depends on associative memory. Neurological double dissociations between regulars and irregulars strengthen the dual-system view. The computation of real and novel, regular and irregular past tense forms was investigated in 20 aphasic subjects. Aphasics with non-fluent agrammatic speech and left frontal lesions were consistently more impaired at the production, reading, and judgment of regular than irregular past tenses. Aphasics with fluent speech and word-finding difficulties, and with left temporal/temporo-parietal lesions, showed the opposite pattern. These patterns held even when measures of frequency, phonological complexity, articulatory difficulty, and other factors were held constant. The data support the view that the memorized words of the mental lexicon are subserved by a brain system involving left temporal/temporo-parietal structures, whereas aspects of the mental grammar, in particular the computation of regular morphological forms, are subserved by a distinct system involving left frontal structures.  相似文献

According to dual-system theories, instrumental learning is supported by dissociable goal-directed and habitual systems. Previous investigations of the dual-system balance in healthy aging have yielded mixed results. To further investigate this issue, we compared performance of young (17–24 years) and older (69–84 years) adults on an instrumental learning task. Following the initial learning phase, the behavioral autonomy of the motivational significance of the instrumental outcome was assessed with an outcome-devaluation test and slips-of-action test. The present study provides evidence for a disrupted dual-system balance in healthy aging, as reflected in reduced outcome-induced conflict during acquisition, as well as in impaired performance during the test stage, during which participants had to flexibly adjust their actions to changes in the current desirability of the behavioral outcome. These findings will be discussed in relation to previous aging studies into habitual and goal-directed control, as well as other cognitive impairments, challenges that older adults may face in everyday life, and to the neurobiological basis of the developmental pattern of goal-directed action across the lifespan.  相似文献

Dual-system models explain social cognition and behavior as a joint function of 2 interconnected mental faculties, each operating according to different principles. In this article, we use the Reflective-Impulsive Model as an example and first describe 3 major advantages of dual-system models, i.e., their integrative power, their foundation in well-established constructs of cognition and neuroscience; and the ease with which they can explain the interplay of judgments and nonjudgmental processes. We then turn to current debates on the adequate number of systems, as well as on the role of freedom and consciousness. We conclude by stating that dual-system models are versatile tools to integrate existing findings and to stimulate new research in social cognition and beyond.  相似文献

State-trace analysis was used to investigate the effect of concurrent working memory load on perceptual category learning. Initial reanalysis of Zeithamova and Maddox (2006, Experiment 1) revealed an apparently two-dimensional state-trace plot consistent with a dual-system interpretation of category learning. However, three modified replications of the original experiment found evidence of a single resource underlying the learning of both rule-based and information integration category structures. Follow-up analyses of the Zeithamova and Maddox data, restricted to only those participants who had learned the category task and performed the concurrent working memory task adequately, revealed a one-dimensional plot consistent with a single-resource interpretation and the results of the three new experiments. The results highlight the potential of state-trace analysis in furthering our understanding of the mechanisms underlying category learning.  相似文献

A class of dual-system theories of categorization assumes a categorization system based on actively formed prototypes in addition to a separate instance memory system. It has been suggested that, because they have used poorly differentiated category structures (such as the influential “5-4” structure), studies supporting the alternative exemplar theory reveal little about the properties of the categorization system. Dual-system theories assume that the instance memory system only influences categorization behaviour via similarity to single isolated instances, without generalization across instances. However, we present the results of two experiments employing the 5-4 structure to argue against this. Experiment 1 contrasted learning in the standard 5-4 structure with learning in an even more poorly differentiated 5-4 structure. In Experiment 2, participants memorized the 5-4 structure based on a five minute simultaneous presentation of all nine category instances. Both experiments revealed category influences as reflected by differences in instance learnability and generalization, at variance with the dual-system prediction. These results have implications for the exemplars versus prototypes debate and the nature of human categorization mechanisms.  相似文献

Organizations sometimes present their members with facades of choice: situations that appear to promise a choice but that, in fact, do not do so. Our study examines how facades of choice, relative to genuine choice, influence justice perceptions and negative and compensatory behavioral reactions. We then consider how the adequacy and timing of explanations for façades of choice affect justice perceptions and negative and compensatory reactions following façades of choice. Results indicate that the impact of explanations is influenced by their adequacy and timing (before or after one actually suffers the broken promise inherent in a façade of choice), suggesting that the experience of an injustice may frame a person's understanding of the explanation given for that injustice.  相似文献

Multinational organisations experience difficulties in finding managers willing to accept international assignments. This study has therefore focused on factors that can predict males' and females' willingness to accept international assignments, or to follow their partners on international assignments. Hypotheses were formulated based on the Rational Choice/Human Capital Theory, the Family Power Theory, the Life Role Salience Theory, and the Psychological Contract Theory. Data were collected using a written questionnaire from 178 male and 122 female employees of a large Anglo-Dutch company. Results using regression analyses showed that male candidates were more willing to accept an overseas assignment and more willing to follow their partners than female ones. Further, the rational choice and family power theories were best able to explain male candidates' willingness, whereas females' willingness was better predicted using variables from the life role salience and psychological contract theories. However, in terms of willingness to follow their partner, all the sets of variables are significant predictors for men, whereas, for women, only rational choice and family power variables explain a significant amount of the variance. The results are discussed in terms of theory and organisational practice.  相似文献

近年来, 情绪对跨期决策的影响逐渐成为一个新的研究趋势。根据情绪发生于跨期决策过程中的时间, 可以将其分为决策前情绪、决策中情绪和决策后情绪。目前关于情绪与跨期决策的研究, 尤其是决策前情绪影响跨期决策的研究, 大多还只是停留在揭示现象的阶段, 较少有研究直接验证其中的影响机制。综合运用行为实验和神经影像学的手段从认知过程和决策过程揭示情绪影响跨期决策的行为机制和神经机制, 将有助于加深对跨期决策心理机制的理解, 并帮助人们更好地利用和控制情绪以做出更满意的决策。未来研究还需加强研究的深度和生态效度, 如考察动态情绪、日常情绪和复杂情绪对跨期决策的影响, 并在情绪干预方面进行更多的尝试和探索。  相似文献

基于自我确认理论开展的大量研究,有助于理解自尊对人际互动行为的调节作用。然而,研究者对自尊的测量工具不尽相同,筛选实验被试的标准也不尽一致,实验范式忽略了对实际人际互动情境的操纵,单纯采用人际选择反应作为测量自我确认的指标,因而难以形成具有整合性的理论模型。今后的研究有必要在编制合适的测量工具的基础上,将整体自尊与特殊自尊作为两个独立的变量置于整合性实验范式下开展研究,同时采用对人际评价信息的认知判断和对评价者的交往选择的双维指标,以全面揭示整体自尊与特殊自尊对自我确认过程的相对作用及其心理机制。  相似文献

Over the past decade, moral judgments and their underlying decision processes have more frequently been considered from a dynamic and multi-factorial perspective rather than a binary approach (e.g., dual-system processes). The agent’s intent and his or her causal role in the outcome–as well as the outcome importance–are key psychological factors that influence moral decisions, especially judgments of punishment. The current research aimed to study the influence of intent, outcome, and causality variations on moral decisions, and to identify their interaction during the decision process by embedding the moral scenarios within an adapted mouse-tracking paradigm. Findings of the preregistered study (final n = 80) revealed main effects for intent, outcome, and causality on judgments of punishment, and an interaction between the effects of intent and causality. We furthermore explored the dynamics of these effects during the decision process via the analysis of mouse trajectories in the course of time. It allowed detecting when these factors intervened during the trial time course. The present findings thus both replicate and extend previous research on moral judgment, and evidence that, despite some ongoing challenges, mouse-tracking represents a promising tool to investigate moral decision-making.  相似文献

内隐序列学习意识理论有二分和渐进两种观点。意识的主观和客观行为测量来源于二分理论, 其研究却产生了渐进理论; 电生理和脑成像测量则存在严重的二分偏向。影响意识的三因素--反应刺激间隔(RSI)、人格开放性和新异刺激都是意识产生的原因, 其有关研究各自支持或反对两种意识理论, 进一步探索可能孕育出新的意识理论。鉴于二分理论无法解释中间意识, 反之渐进理论无法解释意识与无意识的脑区分离, 本文提出双系统渐进理论或可统合两者, 且可能促使大脑网络技术探索意识产生机制的多样性和竞争性等新研究的产生。此外, 所有测量方式的敏感性等级尚待确定, 影响意识三因素的交互作用也值得探索。  相似文献

Using magnetic resonance imaging, De Martino and colleagues investigated the neural signature that is associated with decisions between small sure amounts of money and large riskier amounts when the framing of the outcomes is varied. We interpret their results within a dual-system framework, in which different frames evoke distinct emotional responses that different individuals can suppress to various degrees. The study advances the integration of brain imaging results into cognitive theory.  相似文献
