社会主义核心价值体系的基本属性

尽管学界对社会主义核心价值体系的内涵、理论框架等进行了富有成果的讨论,但对于社会主义核心价值体系的基本属性仍然存在模糊认识.社会主义核心价值体系的基本属性应体现在三个方面:普遍性与民族性、单元性与复合性、保护性与扩展性.即社会主义核心价值体系应具有普遍价值理念,民族精神的精华,道德单元构成,道德单元与道德意识、实践的复合,保护性"硬核",自我完善与不断创新等属性.     

Provision of Genetic Services for Hearing Loss: Results from a National Survey and Comparison to Insights Obtained from Previous Focus Group Discussions

Hearing loss is a common sensory deficit and more than 50% of affected individuals have a genetic etiology. The discovery of 40 genes and more than 100 loci involved in hearing loss has made genetic testing for some of these genes widely available. Genetic services for deafness are also being sought more often due to the early identification of hearing loss through newborn screening services. The motivations for pursuing genetic testing, and how genetic services are provided to the client may differ among individuals. Additionally, information obtained through genetic testing can be perceived and used in different ways by parents of deaf children and deaf adults. This study aimed to follow up on focus group studies published earlier with a quantitative survey instrument and assess the preference of consumers for provision of genetic services. We conducted a national survey of hearing and deaf parents of children with hearing loss and of deaf adults. Data was compared and analyzed by hearing status of the participant, their community affiliation and the genetic testing status using nominal logistic regression. Consistent with our focus group results, the survey participants thought that a genetic counselor/geneticist would be the most appropriate professional to provide genetics services. Statistically significant differences were noted in the preferred choice of provider based on the genetic testing status. Parents preferred that genetic evaluation, including testing, occur either immediately at or a few months after the audiologic diagnosis of hearing loss. This data should help providers in clinical genetics keep patient preferences at the helm and provide culturally competent services.     

影响9点问题解决的关键行为

在已有研究的基础上,作者提出划出第三条线是解决9点问题关键行为的假设,并设计了三个实验来验证假设.结果表明:任意两条线的提示训练使9点问题的解决率接近或达到100%,因而,提示两条线不能被看成是解决9点问题的关键行为;而提示划出第三条线的训练使9点问题的解决率明显高于提示其它任何一条线训练的效果,可以被认为是解决9点问题的关键行为;能够引导被试划出第三条线的训练使9点问题的解决率明显提高.     

Big brown dog or brown big dog? An electrophysiological study of semantic constraints on prenominal adjective order

Event-related brain potentials (ERPs) were recorded while participants read and made acceptability judgments about sentences containing three types of adjective sequences: (1) normal sequences--e.g., Jennifer rode a huge gray elephant; (2) reversed sequences that violate grammatical-semantic constraints on linear order--e.g., *Jennifer rode a gray huge elephant; and (3) contradictory sequences that violate lexical-semantic constraints on compositionality--e.g., *Jennifer rode a small huge elephant. Relative to the control condition, the second adjective elicited a reduced N400 and an enhanced P600 in both the reversal condition and the contradiction condition. We present several alternative accounts of these two effects, but favor an interpretation which treats them as reflecting semantic and syntactic aspects of a temporary reanalysis of the adjective order construction. Furthermore, relative to the control condition, the final noun elicited a robust N400 in the contradiction condition but not in the reversal condition. We suggest that this effect indexes the full registration of the lexical-semantic incompatibility of the two adjectives in the contradiction condition. Finally, we discuss how all of these findings fit into the broader context of recent ERP studies that have reported atypical N400s and robust P600s in response to certain types of semantic anomalies.     

Spoken and gestural production in a naming task by young children with Down syndrome

Lexical production in children with Down syndrome (DS) was investigated by examining spoken naming accuracy and the use of spontaneous gestures in a picture naming task. Fifteen children with DS (range 3.8-8.3 years) were compared to typically developing children (TD), matched for chronological age and developmental age (range 2.6-4.3 years). Relative to TD children, children with DS were less accurate in speech (producing a greater number of unintelligible answers), yet they produced more gestures overall and of these a significantly higher percentage of iconic gestures. Furthermore, the iconic gestures produced by children with DS accompanied by incorrect or no speech often expressed a concept similar to that of the target word, suggesting deeper conceptual knowledge relative to that expressed only in speech.     

生育价值观的理论构建及问卷的初步编制

通过文献综述、开放式调查、专家咨询和小样本测试的统计分析等提出了生育价值观的理论构想,以此为基础自编了育龄青年生育价值观问卷,并对正式问卷调查结果进行了探索性因素分析和验证性因素分析,结果表明：生育价值观是一个多层次和多维度的体系,包括3个二阶因素和9个一阶因素。该研究所构建的生育价值观理论结构比较合理,初步编制的量表需修订和完善。本研究可以为继续探讨人们的生育价值观特征提供有意义的基础。     

学习困难儿童的元记忆监测与控制特点

以有无意义联系的两种中文词对为材料,采用2×3×2混合实验设计,对小学三到五年级学习困难儿童的元记忆监测、控制水平与学优儿童之间的差异及其发展特点进行研究。结果表明：1．学习困难儿童在三种元记忆监测判断等级上均显著低于学优儿童。2．学习困难儿童具有元记忆控制能力,但其控制水平相对低于学优儿童。3．学习困难儿童的元记忆监测判断和学习时间分配之间存在交互影响。4．学习困难儿童的元记忆监测和控制水平存在较为复杂的发展特点。据此得出结论认为,学习困难儿童的元记忆监测与控制能力都比学优儿童差,同时也表现出一定的发展趋势。     

表面特征和结构特征在故事类比通达中的作用

The emotional attentional blink is robust to divided attention

The emotional attentional blink (EAB) refers to a temporary impairment in the ability to identify a target when it is preceded by an emotional distractor. It is thought to occur because the emotional salience of the distractor exogenously captures attention for a brief duration, rendering the target unattended and preventing it from reaching awareness. Here we tested the extent to which the EAB can be attenuated by inducing a diffuse top-down attentional state, which has been shown to improve target identification in an analogous attentional phenomenon, the attentional blink. Rapid sequences of landscape images were presented centrally, and participants reported the orientation of a ± 90° rotation of a landscape target. To induce a diffuse state of attention, participants were given a secondary task of monitoring for the appearance of a colored dot in the periphery. We found that emotional distractors impaired target recognition performance to comparable extents, regardless of whether or not participants concurrently performed the peripheral-monitoring task. Moreover, we found that performance of the secondary task led to an impaired ability to ignore neutral distractors. Subjective ratings of target vividness mirrored the behavioral accuracy, with frequent reports of intermediate levels of vividness suggesting that the EAB might impair target visibility in a graded manner. Our results demonstrate that the EAB is robust to manipulations of top-down attention, suggesting that the temporary capture of attention by emotionally salient stimuli involves processes that are distinct from those that produce the attentional blink.
