为什么被选的和被拒的会是同一个备择选项?

选项的排列和描述方式会对人们的决策产生重大影响, 选择和拒绝反应模式作为描述方式中的特殊变式, 其研究价值和应用潜力被研究者低估。靠“选择和拒绝”反应模式达成决策时的差异表现在认知努力、选择注意力、决策标准等5个层面, 近30年来逐渐发展出了丰富选项范式、分阶段缩小技术和直接询问法等研究范式, 并探索出兼容性假说、承诺假说和强调假说等较为成熟的理论假说, 用以阐述选择和拒绝反应模式差异的内在机制。选择和拒绝反应模式已在消费者行为、医疗卫生等领域中发挥出实在的推动作用, 未来研究可考虑着眼于选择和拒绝反应模式作为助推手段的应用价值和助推实践。     

On the relationship between phonological awareness,morphological awareness and Chinese literacy skills: evidence from an 8‐year longitudinal study

The present study reported data on phonological awareness, morphological awareness, and Chinese literacy skills of 294 children from an 8‐year longitudinal study. Results showed that mainland Chinese children's preliterate syllable awareness at ages 4 to 6 years uniquely predicted post‐literate morphological awareness at ages 7 to 10 years. Preliterate syllable awareness directly contributed to character reading and writing at age 11 years, while post‐literate phonemic awareness predicted only character reading at age 11 years. In addition, preliterate syllable and morphological awareness at ages 4 to 6 years had indirect effects on character reading and writing, reading fluency, and reading comprehension at age 11 years, through post‐literate morphological awareness at ages 7 to 10 years. Findings underscore the significant role of syllable awareness in Chinese character reading and writing, and the importance of morphological awareness in character‐level processing and high‐level literacy skills. More importantly, our results suggest the unique relation of syllable awareness and morphological awareness in Chinese as they focus on the same unit, which is also likely to map directly onto a character, the basic unit for high‐level Chinese reading skills.     

The relationship between spoken language and speech and nonspeech processing in children with autism: a magnetic event‐related field study

It has been proposed that language impairments in children with Autism Spectrum Disorders (ASD) stem from atypical neural processing of speech and/or nonspeech sounds. However, the strength of this proposal is compromised by the unreliable outcomes of previous studies of speech and nonspeech processing in ASD. The aim of this study was to determine whether there was an association between poor spoken language and atypical event‐related field (ERF) responses to speech and nonspeech sounds in children with ASD (n = 14) and controls (n = 18). Data from this developmental population (ages 6–14) were analysed using a novel combination of methods to maximize the reliability of our findings while taking into consideration the heterogeneity of the ASD population. The results showed that poor spoken language scores were associated with atypical left hemisphere brain responses (200 to 400 ms) to both speech and nonspeech in the ASD group. These data support the idea that some children with ASD may have an immature auditory cortex that affects their ability to process both speech and nonspeech sounds. Their poor speech processing may impair their ability to process the speech of other people, and hence reduce their ability to learn the phonology, syntax, and semantics of their native language.     

汉语双音节同音词词汇歧义消解过程的研究

使用跨通道词汇判断任务和语义启动技术,两个实验分别考察了孤立状态下和句子语境中汉语双音节同音词意义通达的情况,结果发现(1)在孤立状态下,无论ISI为0毫秒还是-150毫秒,与同音词主要或次要意义有关的探测词都受到了促进;(2)当ISI为0毫秒时,在语境一致的条件下,与同音词主要或次要意义有关的探测词均受到了促进,在语境不一致的条件下,则未发现任何促进效应;(3)当ISI为-150毫秒时,只是在语境一致并且探测词与同音词的主要意义有关的条件下才观察到促进效应。     

动词隐含因果性对代词加工的影响

本研究探讨了在汉语句子理解中动词隐含因果性对代词指认的影响。在实验一巾,被试进行自定步速的阅读．结果发现当动词隐含因果性和句中代词实际所指一致时阅读时间较短,不一致时阅读时间较长。实验二采用眼动技术,句中两个参与者性别不同,代词上提供性别线索,结果显示了动词隐含因果性在代词加工上微弱的即时效应。     

珠心算过程的眼动和认知研究

本实验采用眼动技术和实验神经心理学的方法对珠心算的认知过程进行了实验研究。研究发现,在竖式运算时,接受过珠心算训练的儿童与没有接受过珠心算训练的儿童相比其眼动轨迹显著不同;神经心理实验的结果表明,训练组儿童在数学运算能力、数字记忆空间、注意力、大脑功能偏侧化等方面均与非训练组儿童有显著差别。     

句子语境中汉语词类歧义词的意义激活

以单字词为实验材料 ,采用跨通道启动真假字判断任务 ,在句子语境中考察汉语词类歧义词不同意义激活的特点。被试为 134名北京师范大学本科学生。实验时向被试听觉呈现含有歧义词的句子 ,且句子语境分别支持歧义词的主要或次要意义 ,以不同的ISI分别呈现与歧义词两种意义有关的视觉目标词。结果发现 ,当探测目标词在最短的ISI出现时 ,与语境支持的意义有关的目标词反应时较短 ,表明语境在歧义词加工早期促进合适意义的激活 ,同时限制不合适意义的激活。实验数据支持相互作用理论     

论心理学基本理论问题的研究

心理学的基本理论问题,是心理学上老大难问题,一直没有得到好好解决。这些问题比较复杂,不容易解决,不容易碰,但不能回避,不能不去碰它们。我国心理学要大步跨上去,要赶超世界先进水平,要很好地为社会主义现代化建设服务,非尽可能研究解决这些问题不可。     

Mementos and the endowment effect

This research provides evidence for a new moderator of the endowment effect: having a memento of the endowed object. Three studies adapting classic endowment effect paradigms and using a variety of endowment objects and mementos demonstrate that having a memento of an endowment increases willingness to trade the endowment and decreases selling prices for the endowment. We provide evidence that mementos attenuate the endowment effect regardless of whether the memento is a separate small gain when facing the loss of the endowment or a small part of the original endowment that is kept. Examining mementos in context of the endowment effect not only provides insight into the psychology underlying the reluctance to part with one's endowment but also other consumer disposition behaviors.
