There is increasing recognition that consumer aesthetics—the responses of consumers to the aesthetic or appearance aspects of products—has become an important area of marketing in recent years. Consumer aesthetic responses to a product are a source of pleasure for the consumer. Previous research into the aesthetic responses to products has often emphasized exterior factors and visual design, but studies have seldom considered the psychological aesthetic experience of consumers, and in particular their emotional state. This study attempts to bridge this gap by examining the link between consumers’ emotions and their aesthetic response to a product. Thus, the major goal of this study was to determine how valence‐based and discrete emotional states influence choice. In Studies 1 and 2, positive and negative emotions were manipulated to implement two different induction techniques and explore the effect of emotions on participants’ choices in two separate experiments. The results of both experiments confirmed the predictions, indicating that aesthetic responses and purchase intention are functions of emotional valence, such that both are stronger for people in a positive emotional state than for those in a negative emotional state. Study 2 also used a neutral affective state to establish the robustness of this observed effect of incidental affect. The results of Study 3 demonstrate that aesthetic response and purchase intention are not only a function of affect valence, but also are affected by the certainty appraisal associated with specific affective states. This research, therefore, contributes to the literature by offering empirical evidence that incidental affect is a determinant of aesthetic response. 相似文献

启动是经验对当前任务的易化作用.重复抑制是刺激重复导致的皮层神经活动减少.大量研究表明启动与重复抑制密切相关.该文以理论假设对启动研究结果的解释效力为依据,对近期认知领域内有关启动和重复抑制的研究进行梳理,评介三种理论解释启动神经机制的适用性和局限性.指出未来研究可以考虑细化启动成分和重复抑制的具体关系,并尝试在此基础上建立神经元、重复抑制和行为启动的整合理论.这将对启动神经机制的理解具有重要意义. 相似文献

When a stationary object begins to move, visual spatial attention is reflexively deployed to the location of that object. We tested whether this capture of attention by new motion is entirely stimulus driven, or whether it is contingent on an observer's goals. Participants monitored a visual display for a colour change, inducing an attentional control set (ACS) for colour. Across the three performed experiments, irrelevant new-motion cues always captured visual spatial attention, despite the ACS for colour. This persistence of the attentional cueing effect demonstrates that ACSs, in particular an ACS for colour, cannot prevent new motion from capturing attention. Unlike other stimulus types, such as luminance changes, colour singletons, and new objects, new motion may always capture attention regardless of an observer's goals. This conclusion entails that new motion is an important determinant of when, and to where, visual spatial attention is deployed. 相似文献

The structure of a Cd68Mg12Dy20 crystalline phase denoted as the φ-phase, which has a composition close to that of the Cd66Mg21Dy13 icosahedral quasicrystalline phase, has been investigated by electron diffraction and scanning transmission electron microscopy (STEM). The φ phase has a fcc lattice with a = 21.6Å. High-angle annular dark-field STEM with Z contrast confirms that the phase has the Cd45Sm11-type structure. The atomic cluster in the structure is shown to be characterized by a Friauf polyhedron with tetrahedral symmetry. 相似文献

This study investigated the influence of social comparison on career choice certainty and its potential mechanisms: regret as a mediator and vocational identity as a moderator. Before the formal experiment, 30 pairs of vocational values representing typical conflicts in career decision-making for Chinese university students were obtained. The formal experiment adopted a single-factor (social comparison VS no comparison) between-subject design with vocational identity as an independent covariate. Ninety-eight junior and senior undergraduate students and graduate students in a university in China were invited to participate in the computer-controlled experiment, which involved vocational identity assessment, social comparison manipulation, and analogue career-choice scenario tests. Path analysis showed that: (a) Social comparison significantly and negatively predicted career choice certainty; (b) Regret partially mediated the effect of social comparison on career choice certainty; and (c) Vocational identity did not moderate the path between social comparison and regret, but significantly moderated the negative effect of regret on career choice certainty. These results indicated that in the collectivistic Chinese culture, individuals' career development trajectories may not be totally independent and are subject to influences by other people's choices, while emotion of regret and vocational identity development all play significant roles in this intricate process. 相似文献

The temperature-dependent elastic constants of body-centred cubic (bcc) phase W are presented from first principles quasi-static approach. With the quasi-harmonic approximation model, the Hugoniot equation of state and temperature-dependence linear thermal expansion coefficient is successfully obtained. The adiabatic elastic constants show a normal behaviour with temperature: decrease with increasing temperature. Based on the obtained adiabatic elastic constants, the structural stability and polycrystalline aggregate properties including bulk modulus B, shear modulus G, and B/G ratio are analysed for bcc phase W. In addition, the sound velocities as a function of temperature for bcc phase W are predicted. 相似文献

具身-生成取向正在引领当代认知科学加速发展,然而学术界在理解“具身-生成”的内涵上却正陷入“战国时代”,这严重影响了该取向的理论效力.通过分析来自交叉学科的相关证据,发现“具身”与“生成”既有联系,又有区别,两者相互支撑.具身认知主要考察嵌入在社会情境中的身体结构、活动、内容与形式对认知活动的影响.“生成”强调认知结构在大脑、身体与环境的结构性耦合中涌现出来的动态机制,尤其是知觉-行动环路的作用.未来,具身-生成的认知科学只有在应对来自经典认知科学的挑战过程中才有可能走出“战国时代”. 相似文献

The Role of Stimulus Type and Semantic Category‐Level Attentional Set in Sustained Inattentional Blindness 下载免费PDF全文
Abstract: We examined the effect of the stimulus type and semantic categorization of the unexpected stimulus on sustained Inattentional Blindness (IB). Results showed that observers could establish attentional set based on a higher level of semantic categorization, which tuned one's attention to prioritizing semantic content over others. The unexpected stimulus, congruent with the attended objects in semantic categorization, was more likely to be noticed, whereas the incongruent semantic stimulus seemed to be unseen. Semantic category‐level attentional set played a crucial role in breaking through IB. The semantically congruent Chinese characters stimulus was detected and recognized more often than a semantically congruent picture stimulus, indicating that Chinese characters had more power to attract attention to escape sustained IB than pictures involved in visual processing. Presumably the finding of Chinese characters breaking through IB more easily might be due to the fact that Chinese characters look more distinct from pictures, rather than Chinese characters being processed more easily. Further research should be taken to test the semantic processing efficiency between pictures and Chinese characters in sustained IB. 相似文献
