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。 相似文献

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。 相似文献

All therapists have values, assumptions, and beliefs about groups of people who are different from the dominant culture. How the therapeutic process is shadowed by therapists' assumptions and attitudes toward ethnic minorities is discussed. The author provides experiential techniques such as visualization, role playing, role reversal, family sculpturing, and a written assignment as a vehicle to heighten a family therapists' awareness of underlying assumptions and biases toward clients of an ethnic minority. 相似文献

An experimental instructional program based mainly on an equal-whole schema in fractions was given to two fourth-grade classes of a Japanese elementary school. As a control, conventional teaching based on a traditional Japanese textbook was given to another fourth-grade class. The study tested the hypothesis that students given the experimental program would understand order and magnitude as central characteristics of fractions better than those who were instructed using the traditional textbook. Students in the experimental group showed better understanding of both the order of fractions and the representation of the sizes of fractions than did the textbook group. However, there were no differences between the experimental and textbook groups in the performance of assessment tasks which were less related to the equal-whole schema. These results are discussed in view of the important instructional aim of having students understand fractions. 相似文献

This study analyzed generalization effects found associated with a language-training intervention to modify the articulation (/f/ phoneme) of a 3.5-year-old boy. The McLean and Raymore Stimulus Shift Articulation Program was implemented by the subject's mother. This language training program is designed to produce setting generalization effects based on an intratherapy training model (i.e., systematic training is applied in a single setting to promote transfer effects to nontraining environments). The intervention resulted in a significant improvement in the subject's production of the /f/ phoneme within the clinical setting in response to untrained stimuli (stimulus generalization). Additionally, the subject's correct phoneme production was observed to generalize to his home and school settings (setting generalization) under “opportunity loaded” (picture prompts) and “spontaneous” (no prompts) conditions. The results provide case-study evidence that stimulus generalization, both within and across settings, may occur with exclusively intratherapy articulation training. 相似文献

The present study investigated differences in infant imitation after watching a televised model and a live model and addressed the issue of whether action effects influence infants’ action control in both cases. In a 2 × 2 design, 12-month-old infants observed a live or a televised model performing a three-step action sequence, in which either the 2nd or the 3rd action step was combined with an acoustical action effect. We assumed that infants would use the observed action-effect relations for their own action control in the test phase afterwards. Even though results exhibited differences in the absolute amount of imitation between the two demonstration groups, both groups showed similar result patterns regarding the action effect manipulation: infants imitated the action step that was followed by a salient action effect more often and mostly as the first target action, emphasizing the important role of action effects in infants’ action control. 相似文献

A word-by-word human sentence processing complexity metric is presented. This metric formalizes the intuition that comprehenders have more trouble on words contributing larger amounts of information about the syntactic structure of the sentence as a whole. The formalization is in terms of the conditional entropy of grammatical continuations, given the words that have been heard so far. To calculate the predictions of this metric, Wilson and Carroll's (1954) original entropy reduction idea is extended to infinite languages. This is demonstrated with a mildly context-sensitive language that includes relative clauses formed on a variety of grammatical relations across the Accessibility Hierarchy of Keenan and Comrie (1977). Predictions are derived that correlate significantly with repetition accuracy results obtained in a sentence-memory experiment (Keenan & Hawkins, 1987). 相似文献

This study aimed to examine the role of attitudes towards psychotherapy and countertransference dimensions as predictors of professional quality of life and burnout among psychotherapists in Iran. Participants were 259 psychotherapists who worked in mental health centres in Tehran (Iran), and they completed the Professional Quality of Life questionnaire, the Therapist Response Questionnaire and the Therapist Attitudes Scale. Professional quality of life was associated with countertransference dimensions and attitude towards psychotherapy. This study concludes that psychotherapists can benefit from working on their specific countertransference issues and re-evaluating their basic attitudes towards psychotherapy to achieve the highest levels of professional satisfaction. Culture may play a role in a specific therapist's attitude and difficulties in addressing certain aspects of countertransference. 相似文献
