The effect of unimanual practice of the non-preferred hand on manual asymmetry and manual preference for sequential finger movements was evaluated in right-handers before, immediately after, and 30 days following practice. The results demonstrate that unimanual practice induced a persistent shift of manual preference for the experimental task in most participants, but no significant correlation between manual asymmetry and manual preference was detected. These findings are explained by proposing that manual preference is influenced by a task-specific confidence developed from the recent history of differential use of the limbs, in interaction with a generalized confidence on a single hand for performance of motor skills. 相似文献

In the research area of multiple criteria decision making, very few publications exist that explicitly design the simulation of a decision maker (DM) in an interactive approach. For this reason, we outline some methods widely used in the literature to identify common assumptions of simulating the DM's responses and the required input preference information. Our paper aims at covering the identified gap by introducing experimental concepts. Such concepts are used for theoretical analyses of a combined search‐and‐decision‐making procedure. Simulating the DM is a fruitful idea because the algorithm can be tested without integrating a human decision maker. Finally, we conduct experiments based on the proposed settings for a multiobjective inventory routing problem, which is a relevant and challenging logistic problem.

Researchers have evaluated a variety of methods for assessing preference for social interactions, and generally have found that such assessments accurately identify differentially reinforcing, preferred interactions. However, few researchers have compared methods for assessing preference for social interactions, and none have done so with participants across different skill levels. The current study compared the stability and validity of hierarchies produced by social interaction preference assessments (SIPA) and picture-based multiple stimulus without replacement preference assessments (MSWO) with 8 individuals diagnosed with autism spectrum disorder (ASD). The MSWO most often produced valid hierarchies for participants who could match, identify, and tact pictures of social interactions and that the SIPA most often produced valid hierarchies for participants who could not identify or tact pictures of social interactions. A vocal paired-stimulus preference assessment (PSPA) was also conducted with a subset of participants who communicated vocally, and it produced valid hierarchies. Considerations and recommendations for selecting a method of assessing preference for social interactions are discussed. 相似文献

童年中期同伴关系与孤独感的中介变量检验 总被引:9,自引:0,他引:9
以571名小学三、四、五、六年级的儿童为被试,考察了儿童社会喜好、友谊质量、社交自我知觉与孤独感的关系,检验了社交自我知觉在同伴关系变量与孤独感间的中介作用。结果表明,社会喜好、友谊质量、社交自我知觉和孤独感间相关显著,并且存在显著的性别差异;社交自我知觉在同伴关系变量与孤独感间存在中介的作用;独立的中介效应检验中,社会喜好、友谊质量均通过社交自我知觉的中介作用与孤独感发生联系,同时,也存在直接的联系;综合模型中,社会喜好只通过社交自我知觉的中介作用与孤独感产生联系,不存在直接效应,而友谊质量与孤独感既存在中介的联系,同时也存在直接联系。 相似文献

消费行为研究中的联合分析法 总被引:11,自引:1,他引:11
联合分析(Conjoint Analysis)是一种定量的研究消费者选择偏好的方法。虽然从它诞生到现在只有40年的历史,但它对消费者行为学的影响很大,它的发展更是日新月异。文章首先介绍了联合分析的基本概念,然后重点阐述了联合分析的原理、步骤和发展历程,最后对联合分析的发展方向作了一个简要概括。 相似文献

社会排斥的现象在当今社会日益凸显,已成为世界各国探究社会政策和不平等问题的一个重要方向。然而却鲜少有研究从心理机制的角度探讨社会排斥对人们的产品偏好的影响。本文通过1个预实验和4个主实验,系统研究了社会排斥如何影响个体对不同触感产品的偏好,并探讨了其内在影响机制。实验结果发现在经历社会排斥(相较于社会接纳)之后,个体更偏好触感柔软的产品,消极心理体验是其内在驱动机制,并且该作用机制被归属感的重要性所调节。当归属感被认为很重要时,个体在经历社会排斥后对柔软触感产品的偏好以及消极心理体验的中介作用会被强化,而当归属感被认为不重要时,以上效应会被削弱。本文还对研究结论的理论贡献和实践应用进行了深入讨论。 相似文献

Behavioral assessment procedures were used to prescribe and evaluate treatments of maladaptive behavior for 2 children with severe multiple handicaps. In Experiment 1, the results of an assessment of reinforcer preference were used in conjunction with a functional analysis of the conditions maintaining self-injurious behavior to prescribe a treatment for a child with severe disabilities. The treatment procedure involved the use of a pressure-sensitive microswitch to activate reinforcing stimuli during two solitary conditions, during which self-injurious behavior had occurred at high rates. The results were evaluated with a multiple baseline across settings design and indicated that self-injury decreased with concomitant increases in microswitch activation. Results were maintained at 6 weeks, 8 weeks, and 6 months. In Experiment 2, the results of behavioral assessments of reinforcer preference and self-injurious behavior were combined to develop a treatment for a second severely handicapped child, who exhibited high rates of self-injury in demand situations. This treatment was evaluated with a multiple baseline across tasks design and resulted in the elimination of self-injury for up to 15 months. 相似文献

Two laboratory experiments demonstrated that Japanese participants did not conform to the majority unless negative social implications of not conforming were clear. When their behaviour had no implications for others, they rather exhibited preference for uniqueness. Results of Study 2 further demonstrated that participants' conformity to the majority was particularly prevalent among those who were chronically concerned with how other people would perceive them. Participants in these studies were shown to be cultural game players who changed their behaviour in response to anticipated responses of others based on culturally shared beliefs. 相似文献

This paper discusses least squares methods for fitting a reformulation of the general Euclidean model for the external analysis of preference data. The reformulated subject weights refer to a common set of reference vectors for all subjects and hence are comparable across subjects. If the rotation of the stimulus space is fixed, the subject weight estimates in the model are uniquely determined. Weight estimates can be guaranteed nonnegative. While the reformulation is a metric model for single stimulus data, the paper briefly discusses extensions to nonmetric, pairwise, and logistic models. The reformulated model is less general than Carroll's earlier formulation.The author is grateful to Christopher J. Nachtsheim for his helpful suggestions. 相似文献
