注意范围分布对视觉工作记忆巩固过程的影响

以往研究发现个体能够同时巩固一定数量的项目信息进入视觉工作记忆系统。本研究将考察视觉工作记忆的巩固容量是否会受到分配到记忆项目上的注意资源量的影响。实验1在同时序列掩蔽范式的基础上, 用控制记忆项目呈现区域的大小的方法操纵被试的注意范围, 从而达到操纵分配到单个项目上的注意资源量的目的。研究结果显示, 被试的记忆成绩随着注意范围的扩大显著降低, 但在并行和序列呈现条件之间不存在显著差异; 实验2则证实实验1中对注意资源量分配的控制不会影响对项目的知觉编码效率。本研究结果表明, 分配在记忆项目上的注意资源量能够影响记忆巩固的效率, 但不会影响巩固容量。     

Forward inference in risky choice: Mapping gaze and decision processes

The study of cognitive processes is built on a close mapping between three components: overt gaze behavior, overt choice, and covert processes. To validate this overt–covert mapping in the domain of decision‐making, we collected eye‐movement data during decisions between risky gamble problems. Applying a forward inference paradigm, participants were instructed to use specific decision strategies to solve those gamble problems (maximizing expected values or applying different choice heuristics) during which gaze behavior was recorded. We revealed differences between overt behavior, as indicated by eye movements, and covert decision processes, instructed by the experimenter. However, our results show that the overt–covert mapping is for some eye‐movement measures not as close as expected by current decision theory, and hence question reverse inference as being prone to fallacies due to a violation of its prerequisite, that is, a close overt–covert mapping. We propose a framework to rehabilitate reverse inference.     

Gender role orientation,thinking style preference and facets of adult paranormality: A mediation analysis

This study examines the extent to which masculine and feminine gender role orientations predict self-reported anomalous experiences, belief, ability and fear once relevant correlates including biological sex are controlled for. The extent to which rational versus intuitive thinking style preference mediates these relationships is also examined. Path analysis (n = 332) found heightened femininity directly predicts stronger intuitive preference plus more anomalous experiences, belief and fear with, additionally, intuitive preference mediating several gender role-paranormality relationships. By comparison, heightened masculinity directly predicts both thinking styles plus lower anomalous fear. The latter relationship is also shaped by the nature of mediators with (a) more anomalous experiences and belief associated with more anomalous fear and (b) either heightened rationality else more anomalous ability linked to, conversely, less anomalous fear. The extent to which findings support a gender (or social) role account of adult paranormality, together with methodological limitations and ideas for future research, is discussed.     

A mechanism for biasing the appraisal process in affective agents

In this paper we present a mechanism to model the influence of agents’ internal and external factors on the emotional evaluation of stimuli in computational models of emotions. We propose the modification of configurable appraisal dimensions (such as desirability and pleasure) based on influencing factors. As part of the presented mechanism, we introduce influencing models to define the relationship between a given influencing factor and a given set of configurable appraisal dimensions utilized in the emotional evaluation phase. Influencing models translate factors’ influences (on the emotional evaluation) into fuzzy logic adjustments (e.g., a shift in the limits of fuzzy membership functions), which allow biasing the emotional evaluation of stimuli. We implemented a proof-of-concept computational model of emotions based on real-world data about individuals’ emotions. The obtained empirical evidence indicates that the proposed mechanism can properly affect the emotional evaluation of stimuli while preserving the overall behavior of the model of emotions.     

权力对延迟选择的影响

本研究旨在考察权力对延迟选择的影响, 并探讨决策难度在其中的调节作用以及决策过程的中介作用。两个实验均先操纵个体的权力状态, 然后再请被试完成随后的延迟选择任务。结果发现, 决策难度可调节权力对延迟选择的影响, 当决策困难时, 高权力者具有更低的延迟倾向, 当决策容易时, 权力的影响消失。决策过程的加工变异性可中介权力对延迟选择的影响。结果表明, 低权力者比高权力者具有更高的延迟倾向(尤其当决策困难时), 不同权力水平者在决策过程上的差异或可部分解释此种现象。     

Integrating a cognitive computational model of planning and decision-making considering affective information

Planning and decision-making are two of the cognitive functions involved in the solution of problems. These functions, among others, have been studied from the point of view of a new field known as cognitive informatics focused on the development of cognitive architectures, autonomous agents, and human robots that are capable of showing human-like behavior. We present an exhaustive study of current biological and computational models proposed in the fields of neuroscience, psychology, and cognitive informatics. Also, we present a deep review of the brain areas involved in planning, decision-making, and affection. However, the majority of the proposed computational models are seeking to mimic human external behavior. This paper aims to contribute to the cognitive informatics field with an innovative cognitive computational model of planning and decision-making. The two main differences of our model with respect to the current models in the literature are: (i) our model considers affective and motivational information as a basic and essential trigger in planning and decision-making processes; (ii) our model attempts to mimic both the internal human brain as well as the external human behavior. We developed a computational model capable of offering a direct mapping from human brain areas to computational modules of our model. Thus, in this paper we present our model from a conceptual, formal, and computational approach in order to show how our proposal must be implemented. Finally, a set of tests were conducted in order to validate our proposal. These tests show an interesting comparison between the behavior of our prototype and the behavior exhibited by some people involved in a case study.     

A reflection on learning crafts as a practice for self-development

This paper represents a reflection on craft as a process that stimulates self-development. Central to this approach is the perception of craft, not as a means of production, but as an exercise of relating to the world. The paper suggests that through the dialogue between the mind, body and environment craft practitioners experience a particular form of connection with the world that reshapes their perceptual and conceptual understanding of it. Rather than following an ego-driven tendency to control, a craftsperson is exposed to modes of ‘knowing’ and ‘being’ that embrace the inherent uncertainty of a complex world. The learning experience of a novice (lead author) demonstrates such a course of development in this paper. In particular, the liminal space that needs to be created for the dialogue between the self and the non-self is explored. This personal narrative is woven together with the experience of craft masters within different social contexts and value systems (from traditional to modern to postmodern) and their views on the process of being and becoming a craftsperson.     

Winding paths: Ambivalence in consumers' buying processes

This paper investigates ambivalence in the buying process. The existing literature has rarely studied ambivalence in longitudinal processes and has therefore not been able to capture its dynamics. Those studies that have studied ambivalence longitudinally have focused on general attitudinal ambivalence rather than its subtypes (cognitive, affective, and intercomponent ambivalence) and have therefore ignored some of the more detailed dynamics. Hence, this study addresses these different types of ambivalence longitudinally, exploring what these different ambivalences consist of, what their roles are in the buying process, and how they occur under different types of involvement conditions. A longitudinal video diary method is used in conjunction with a multimodal analysis technique to explore not only the verbally expressed aspects of ambivalence but also its nonverbal expression, which further reveals differences between different types of ambivalence. The findings suggest that cognitive ambivalence involves conflicting evaluations of utilitarian brand and product aspects and is resolved through more effortful mechanisms, whereas intercomponent ambivalence involves conflicting evaluations of varying utilitarian, hedonic, and symbolic brand and product aspects and is resolved through both more and less effortful mechanisms. Finally, affective ambivalence involves conflicting anticipations about the outcome of the buying process but is not resolved through similarly clear mechanisms. As the key outcome of the exploration, propositions and a synthesising framework about the different types of ambivalence in the buying process are developed for future research. This paper hence contributes to the ambivalence literature and offers managerial implications especially for marketers of multifaceted and high‐involvement products.
