国家青年排球队员时间管理倾向与自我价值感的相关研究

运用时间管理倾向量表和自我价值感量表对13名国家青年排球队运动员的研究表明,国家青年排球队运动员的整体时间管理倾向与大学生没有显着差异;自我价值感显着高于常模群体,具有较高的自我价值感水平;相关分析发现,时间监控观与总体自我价值感和一般自我价值感之间的相关显着,时间监控观与社会取向的家庭自我价值感、时间管理倾向的三维度与个体自我价值感之间存在显着的相关;多重回归分析发现时间监控观对总体自我价值感和一般自我价值感具有直接的预测作用。     

4～6岁儿童直接推理能力及策略的实验研究

采用定量与定性相结合的研究方法,对4－6岁儿童的直接推理能力进行了实验研究,结果表明：（1）学前儿童萌发了评议条件下的直接推理能力,但年龄发展效应并不明显;（2）对于学前儿童而言,否定前提下的直接推理并不比肯定前提的难。但是,如果进行了反义词的转换,同样的任务,却增加了肯定前提下直接推理的任务难度,而对否定前提下的直接堆理没有影响;（3）学前儿童在直接推理时多种策略并存,随着年龄的增长,有效策略的生成能力有了明显的提高,但有效策略的使用能力并没有与有效策略的生成能力同步发展,而是表现为落后的趋势。

计时和计数的相似与差异

计时指判断时距的长短, 计数指辨别刺激呈现数目的多少。研究者发现计时和计数具有相似性, 表现在类似的基本原理, 对时间和数目的记忆都受到时间延迟的影响, 跨通道效应类似, 而且药物对它们的影响一致。模式控制模型认为计时和计数共享同一机制, 量值理论的观点是时间和数目等不同维度具有部分重叠的同一表征形式。计时和计数都激活了前额、顶叶、小脑等区域, 但两者在行为结果和激活的脑区上也有部分差异。计时和计数具有同一表征还是两者独立加工, 只在对比反应阶段存在共同机制仍需要进一步研究。     

Unilateral implicit motor learning deficit in developmental dyslexia

It has been suggested that developmental dyslexia involves various literacy, sensory, motor skill, and processing speed deficits. Some recent studies have shown that individuals with developmental dyslexia exhibit implicit motor learning deficits, which may be related to cerebellar functioning. However, previous studies on implicit motor learning in developmental dyslexics have produced conflicting results. Findings from cerebellar lesion patients have shown that patients' implicit motor learning performance varied when different hands were used to complete tasks. This suggests that dyslexia may have different effects on implicit motor learning between the two hands if cerebellar dysfunction is involved. To specify this question, we used a one-handed version of a serial reaction time task to compare the performance of 27 Chinese children with developmental dyslexics with another 27 age-matched children without reading difficulties. All the subjects were students from two primary schools, Grades 4 to 6. The results showed that children with developmental dyslexic responded more slowly than nondyslexic children, and exhibited no implicit motor learning in the condition of left-hand response. In contrast, there was no significant difference in reaction time between two groups of children when they used the right hand to respond. This finding indicates that children with developmental dyslexia exhibited normal motor skill and implicit motor learning ability provided the right hand was used. Taken together, these results suggested that Chinese children with developmental dyslexia exhibit unilateral deficits in motor skill and implicit motor learning in the left hand. Our findings lend partial support to the cerebellar deficit theory of developmental dyslexia.     

Dissociation and association of the embodied representation of tool-use verbs and hand verbs: An fMRI study

Embodied semantic theories suppose that representation of word meaning and actual sensory-motor processing are implemented in overlapping systems. According to this view, association and dissociation of different word meaning should correspond to dissociation and association of the described sensory-motor processing. Previous studies demonstrate that although tool-use actions and hand actions have overlapping neural substrates, tool-use actions show greater activations in frontal–parietal–temporal regions that are responsible for motor control and tool knowledge processing. In the present study, we examined the association and the dissociation of the semantic representation of tool-use verbs and hand action verbs. Chinese verbs describing tool-use or hand actions without tools were included, and a passive reading task was employed. All verb conditions showed common activations in areas of left middle frontal gyrus, left inferior frontal gyrus (BA 44/45) and left inferior parietal lobule relative to rest, and all conditions showed significant effects in premotor areas within the mask of hand motion effects. Contrasts between tool-use verbs and hand verbs demonstrated that tool verbs elicited stronger activity in left superior parietal lobule, left middle frontal gyrus and left posterior middle temporal gyrus. Additionally, psychophysiological interaction analyses demonstrated that tool verbs indicated greater connectivity among these regions. These results suggest that the brain regions involved in tool-use action processing also play more important roles in tool-use verb processing and that similar systems may be responsible for word meaning representation and actual sensory-motor processing.     

汉语形声字声旁家族大小对整字发音的影响

拼音文字阅读中的“家族效应”是语音通达研究的一个重要角度,然而,汉字语音通达的家族效应研究却未见报道。本文运用快速命名的实验范式,对汉字形声字声旁家族大小对整字语音通达的影响进行了研究。结果发现汉字阅读中也存在家族效应,但是与拼音文字正好相反,声旁家族越大,反应时越长,在不规则汉字阅读中表现更为明显,显示了汉语语音通达有别于拼音文字的特殊性。另外,作者在研究基础上提出了一个汉字形声字阅读的模型,以期更深入地揭示汉字形声字阅读的认知机制     

Exploring thematic influences on theme park visitors' satisfaction: An empirical study on Disneyland China

This study aims to explore thematic influences on theme park visitors' satisfaction through user-generated data. To this end, we first used an unsupervised machine learning method, structural topic modeling, and analyzed 112,000 reviews post by visitors to Shanghai Disney Resort from June 16, 2016 to March 4, 2022. Our findings are of great significance for reflecting consumer behavior through user-generated data. Specifically, we find that visitors' satisfaction is highly related to service in the theme park and their playing feeling, and early tourists pay more attention to the experience of specific playing items while later tourists focus on the overall playing experience. In addition, an empirical study is conducted by treating the ratings associated with each review as dependent variable and each topic represented by comments as independent variables, which shows that the relationship between the customer reviews and ratings by tourists becomes less pronounced over time. In other words, as time goes, customers review can reflect their subjective feelings or experience, but the rating is not. We discover the “dynamics” of user-generated data over time and gain a better understanding of the aspects and concerns of visitors' satisfaction over time. The findings of the study contribute to the literature on tourism, service, and consumer behavior while also providing valuable practical implications.     

4—6岁幼儿空间方位传递性推理能力的发展

Spatial accuracy demand in aiming movements: kinematic analysis of subtended angle and tolerance width

Subtended angle has been assumed to be an important factor in both response programming time and kinematic characteristics of aiming movements. Support for this assumption has come mainly from studies in which circular targets have been used. However, with circular targets, the subtended angle covaries with the size of the target in the principal direction of the movement (tolerance width). The purpose of this study was to examine the effects of tolerance width and subtended angle on aiming movement with multiple targets. Participants first hit a 5-cm-diameter circular target located 8 cm to the left of a starting position and then moved another 8 cm left to hit either a 5-cm diameter circular target or a 5- x 1-cm rectangular target oriented either horizontally or vertically, depending on the condition. Analysis showed that reaction times and movement times were longer for the vertical rectangular target, which had a smaller tolerance width than the other two targets. In addition, the vertical rectangular target also showed a greater percentage of secondary-submovement trials, lower movement velocity, and higher peak vertical displacement. Overall, the results indicate that the tolerance width of the target may impose more constraints on aiming movements than subtended angle.
