消费者新产品采纳的特征

成功的新产品开发是企业获取竞争优势的重要因素,但创新产品并非总能得到市场的接受,大多数的新产品扩散往往以失败告终。因此,业界和学界对新产品采纳问题进行了诸多探索。新产品采纳过程是指创新产品从被设计制造出来,到最终被消费者或潜在消费者认识和采用的过程。对相关研究综述发现：以Rogers创新扩散模型为依据,按采纳时间和特征的不同,新产品采纳者可以系统分为早期采纳者和晚期采纳者,二者之间主要从创新性、产品理解和易感性三个维度进行区分。具体来说,早期采纳者具有高创新性、高产品理解和低易感性;晚期采纳者具有低创新性、低产品理解和高易感性。在此基础上,我们探究了各维度下影响消费者新产品采纳的具体因素。未来研究可以从这三个维度出发,结合已有研究的不足以及当前环境、消费特点等进行拓展。     

节律在听觉言语理解中的作用

言语理解是听者接受外部语音输入并且获得意义的心理过程。日常交流中,听觉言语理解受多尺度节律信息的影响,常见有韵律结构节律、语境节律、和说话者身体语言节律三方面外部节律。它们改变听者在言语理解中的音素判别、词汇感知以及言语可懂度等过程。内部节律表现为大脑内神经振荡,其能够表征外部言语输入在不同时间尺度下的层级特征。外部节律性刺激与内部神经活动的神经夹带能够优化大脑对言语刺激的处理,并受到听者自上而下的认知过程的调节进一步增强目标言语的内在表征。我们认为它可能是实现内外节律相互联系并共同影响言语理解的关键机制。对内外节律及其联系机制的揭示能够为理解言语这种在多层级时间尺度上具有结构规律的复杂序列提供了一个研究窗口。     

正确理解知情同意

知情同意最初由美国于18世纪末19世纪初提出,随着社会不断进步,医学科学的不断发展,人们权力意识的不断增强,知情同意作为患者享有的一项权力,医务人员在医疗过程中应遵循的一条原则已日益到人们的关注。然而在现实的医疗实践中人们对这一的理解和认识还存在一定的偏差。正确理解,践行知情同意既是尊重患者的权利,贯彻“以病人为中心”的原则的保证,也能有效地保护医务人员的合法权益。     

Theory of mind: The state of the art*

Abstract

In this article, I reflect on theory of mind as a field (ToM), how it has developed over the years, and focally on the state of current research and theory. Having begun with preschoolers’ understanding of beliefs and desires, the field now includes research from infancy through late life, contributions and contributors from around the world, research on behavior, conversation, neural correlates, gene-environment contributions, evolution, and the social-behavioral antecedents and consequences of the unfolding trajectories of ToM understanding. Several topics in particular portray the current state of the art and my sense of where theory-of-mind research is likely to head in the near future: progressions of theory of mind achievement; cultural experiences plus experiential influences that shape developmental trajectories; developmental cognitive neuroscience; infant ToM insights; research on ToM developments beyond preschool, including children’s increasing interest in and wrestling with extraordinary minds, such as those of God and super-heroes.     

Emotional valence,sense of agency and responsibility: A study using intentional binding

We investigated how the emotional valence of an action outcome influences the experience of control, in an intentional binding experiment. Voluntary actions were followed by emotionally positive or negative human vocalisations, or by neutral tones. We used mental chronometry to measure a retrospective component of sense of agency (SoA), triggered by the occurrence of the action outcome, and a prospective component, driven by the expectation that the outcome will occur. Positive outcomes enhanced the retrospective component of SoA, but only when both occurrence and the valence of the outcome were unexpected. When the valence of outcomes was blocked – and therefore predictable – we found a prospective component of SoA when neutral tones were expected but did not actually occur. This prospective binding was absent, and reversed, for positive and negative expected outcomes. Emotional expectation counteracts the prospective component of SoA, suggesting a distancing effect.     

Intentional action processing results from automatic bottom-up attention: An EEG-investigation into the Social Relevance Hypothesis using hypnosis

Social stimuli grab our attention. However, it has rarely been investigated how variations in attention affect the processing of social stimuli, although the answer could help us uncover details of social cognition processes such as action understanding. In the present study, we examined how changes to bottom-up attention affects neural EEG-responses associated with intentional action processing. We induced an increase in bottom-up attention by using hypnosis. We recorded the electroencephalographic μ-wave suppression of hypnotized participants when presented with intentional actions in first and third person perspective in a video-clip paradigm. Previous studies have shown that the μ-rhythm is selectively suppressed both when executing and observing goal-directed motor actions; hence it can be used as a neural signal for intentional action processing. Our results show that neutral hypnotic trance increases μ-suppression in highly suggestible participants when they observe intentional actions. This suggests that social action processing is enhanced when bottom-up attentional processes are predominant. Our findings support the Social Relevance Hypothesis, according to which social action processing is a bottom-up driven attentional process, and can thus be altered as a function of bottom-up processing devoted to a social stimulus.     

Studying sense of agency online: Can intentional binding be observed in uncontrolled online settings?

Intentional binding is often used as an implicit index of the sense of agency. However, intentional binding research has primarily been conducted in controlled lab environments. During the COVID-19 global pandemic, there has been a shift to implementing studies using online platforms and it is an open question whether the intentional binding effect can be found using an online experimental set-up and participant sample. Here, we address this question by asking online participants to complete the Libet clock version of the intentional binding task, which we make freely available to researchers as a jsPsych (De Leeuw, 2014) plugin. Intentional binding was observed in the form of later keypress estimates and earlier auditory tone estimates, when the auditory tone followed the keypress. These findings confirm that intentional binding can be assessed in online contexts. We discuss these findings in relation to the broader intentional binding literature.     

The effects of embedding social identities on perceived leadership outcomes and the intentional mobilization of group members

According to Identity Leadership, effective leaders make the group matter by embedding social identities in material reality. Across two studies, we explored the potential importance of embedding social identities on group members' perceptions of leader trust, influence, conflict and intentional mobilization. In Study 1, 74 competitive varsity athletes read a vignette describing a coach who was either embedding or not embedding social identities. Participants presented with a coach who was embedding social identities reported significantly greater leader trust, leader influence and intentional mobilization, and significantly lower leader conflict. In Study 2, four football teams each comprising six athletes were assigned to one of two quasi-experimental conditions where a coach either: (1) spent two weeks embedding social identities before spending two weeks not embedding them; or (2) spent two weeks not embedding social identities before spending two weeks embedding them. When a leader stopped embedding social identities after embedding them for two weeks, group members' trust in their leader significantly reduced. When a leader started embedding social identities after not embedding them for two weeks, group members' perceptions of leader trust, leader influence and intentional mobilization significantly increased. Taken together, findings provide preliminary evidence that embedding social identities is beneficial for leader outcomes and intentional mobilization compared to a non-embedding leadership approach.     

The Effects of Benefactor and Beneficiary Characteristics on Helping Behavior

Abstract

This study assessed the effects of perceived need and nearness of the beneficiary and the chronological maturity of the benefactor on helping behavior. The relationship between verbal and objective measures of helping behavior, and the relationship between available resources and helping behavior were also explored. Indian undergraduates (N = 80 men) composed the sample. The results showed that greater perceived need and nearness of the beneficiary, as well as lesser chronological maturity of the benefactor, led to extending greater help. Verbal and objective measures of help did not generally correspond; however, the relationship between verbal and objective measures was modified by the perceived need and nearness of the beneficiary. Resource availability did not have any direct bearing on helping behavior.     

Production of spontaneous and posed facial expressions in patients with Huntington's disease: Impaired communication of disgust

Several studies have reported impairment in the recognition of facial expressions of disgust in patients with Huntington's disease (HD) and preclinical carriers of the HD gene. The aim of this study was to establish whether impairment for disgust in HD patients extended to include the ability to express the emotion on their own faces. Eleven patients with HD, and 11 age and education matched healthy controls participated in three tasks concerned with the expression of emotions. One task assessed the spontaneous production of disgust-like facial expressions during the smelling of offensive odorants. A second assessed the production of posed facial expressions during deliberate attempts to communicate emotion. The third task evaluated HD patients’ ability to imitate the specific facial configurations associated with each emotion. Foul odours induced fewer disgust-like facial reactions in HD patients than in controls, and patients’ posed facial expressions of disgust were less accurate than the posed disgust expressions of controls. The effect was selective to disgust; patients had no difficulty posing expressions of other emotions. These impairments were not explained by compromised muscle control: HD patients had no difficulty imitating the facial movements required to display disgust. Viewed together with evidence of difficulty in other aspects of disgust in HD, the findings suggest that a common substrate might participate in both the processing and the expression of this emotion.
