熟练中－英双语者三语词汇的语义通达

通过两个实验运用跨语言重复启动的范式考察熟练中－英双语者对不熟练的第三语言词汇的语义通达方式。实验1以三语为日语的熟练中－英双语者为被试,实验2以三语为法语的熟练中－英双语者为被试,两个实验都发现了显著的跨语言重复启动效应。实验结果表明,熟练双语者尽管已经形成了直接通达二语词汇概念意义的语义通达方式,但其并没有将此方式迁移到对三语词汇概念意义的通达,他们仍然需要以一语词为中介从而间接通达三语词汇的概念意义。综合先前系列研究的结果初步表明,第二语言的熟练水平是影响晚期双语者语义通达方式的主要因素,晚期双语者记忆表征中的语义通达方式在本质上是一种经验性变化     

The blocking effect of pictorial prompts on sight-word reading

This study replicates and extends previous work showing that pictorial prompts can interfere with the learning of sight words by students with moderate mental retardation. Effects of training with 6 students were assessed during five conditions using an alternating treatments design. In four conditions, words were presented either alone or with a corresponding picture. In a fifth condition, pictures were used to provide feedback. The results showed that acquisition was achieved fastest during the word-alone conditions with 5 students.     

Functional reading for students with developmental disabilities who are linguistically diverse

Students with moderate and severe disabilities often have language deficits that make the acquisition of reading challenging. Sight word instruction of daily living skills is one method of intervention that benefits students with severe disabilities who have not achieved literacy. When students with developmental disabilities are also linguistically diverse, acquisition of reading skills becomes more complex. Sight words must be chosen that are relevant to the students own community. A critical decision in planning sight word instruction is whether to provide instruction in the student's primary language or in English. These issues are discussed and an illustration is given of the heterogeneity among students with developmental disabilities who are linguistically diverse.     

THE EFFECTS OF KNOWN-ITEM INTERSPERSAL ON ACQUISITION AND RETENTION OF SPELLING AND SIGHTREADING WORDS1

The use of well-documented procedures such as shaping, differential reinforcement, and fading may not be the most practical for teaching certain academic behaviors. An alternative procedure of interspersing trials on previously trained items with trials on unknown items has been suggested, but its effects on acquisition and retention have not been systematically examined. This study investigated the effects of interspersing known items during training on new tasks. Six mentally retarded adolescents were given pretests on spelling and sightreading words, which were divided into pools of learned and unlearned items. Training and baseline conditions were implemented concurrently, using a multi-element design. During interspersal training sessions, 10 known words from the pretest were alternately presented with each of 10 test words that were incorrect on the pretest. The ratio of previously mastered words to test words was gradually reduced. During baseline sessions, 10 different test words were presented without alternation of previously known words. During this condition, a procedure involving high-density social reinforcement contingent on task-related behaviors, but not necessarily correct responses, was later introduced, followed by a return to the original noninterspersal baseline. During all conditions, test words were deleted and replaced after meeting a mastery criterion of three consecutive correct trials. Retention tests were administered over learned test words for all conditions, at specified intervals. Results showed that both acquisition and retention of spelling and sightreading words were facilitated by the interspersal procedure. All subjects acquired more words during the interspersal condition than either the high-density or baseline conditions. The effectiveness of the procedure may possibly be attributed to better maintenance of attending behavior to unknown items as a function of the inclusion of known items, which directly increase the amount of reinforcement for correct responses during the early stages of skill acquisition.     

Vulnerability of facial attractiveness perception to early and multi-year visual deprivation

Judgments of facial attractiveness invariably accompany our perception of faces. Even neonates appear to be capable of making such judgments in a manner consistent with adults. This suggests that the processes supporting facial attractiveness require little, if any, visual experience to manifest. Here we investigate the resilience of these processes to several years of early-onset visual deprivation. Specifically, we study whether congenitally blind children treated several years after birth possess the ability to rate facial attractiveness in a manner congruent to normally sighted individuals. The data reveal significant individual variability in the way each newly sighted child perceives attractiveness. This is in marked contrast to data from normally sighted controls who exhibit strong across-subject agreement in facial attractiveness ratings. This variability may be attributable, in part, to atypical facial encoding strategies used by the newly sighted children. Overall, our results suggest that the development of facial attractiveness perception is likely to be vulnerable to early visual deprivation, pointing to the existence of a possible sensitive period early in the developmental trajectory.     

Changes in maternal ratings of children's overt and covert antisocial behavior

Maternal ratings of overt and covert forms of aggression were collected for two samples of children ranging in age from 2 through 12 years. It was hypothesized that longitudinal analyses would show the slope scores for these two forms of aggression to be quite different from each other. The data were consistent with this hypothesis. An effort was made to find alternative explanations for the negative slope for overt antisocial behavior. Alternatively, it was hypothesized that the more extreme cases would not show this negative slope. It was also hypothesized that careful examination of intraindividual curves would identify a significant number of individuals growing from normal to clinical levels of overt antisocial behavior. The findings led to the rejection of both alternative hypotheses. It was hypothesized that overt and covert scores would correlate significantly for first grade boys. It was also assumed that both covert and overt scores would show moderate stability over the 5‐year interval. The findings were consistent with both of these hypotheses. Aggr.

晚清广东学者的经学研究探析

梁启超曾将清代学术的演变分为四个阶段,而将康有为和他本人归入第三期。然而广东学术的发展并不符合这一轨迹。广东学术在道光以前,宋学占主导地位;随着学海堂的创建,汉学成为广东显学,并成为晚清中国经学研究的重镇。道光以前,广东虽治经学的不乏其人,但以《四书》为主,兼及《五经》。学海堂创建后,广东学者以《十三经》为其治经范围,且颇具乾嘉遗风。学海堂创建后,在晚清广东学坛上出现了东塾学派和九江学派．两者既有共同点,也有不同点。九江学派后来又分化出康有为一系和简朝亮一系。康有为走向今文经学,简朝亮则与朱次琦的治学精神一脉相承。     

战国中晚期子家著作中的"亡国"义训

在战国后期的子家著作中,“亡国”一词往往不是用以指陈灭国的事实,而是指称必亡的政治形势,进而也被视作与“王”、“霸”、“危”并立的一种国家类型。作为国家类型的“亡国”,其最明显的特征是君主失制。战国诸子语文中“亡国”含义的多重性表明,上古中国政治思想着眼于如何治理好国家,如何在国际的竞争中生存。这与以城邦为视域的古典希腊政治哲学存在明显不同。     

Do Feelings of Loneliness Mediate the Relationship between Sociocognitive Understanding and Depressive Symptoms During Late Childhood and Early Adolescence?

An interesting association between sociocognitive understanding and depression has been documented in clinical populations, with high levels of depression apparently related to theory-of-mind deficits. Yet no research has so far investigated this relationship among typically developing preadolescents. Therefore, the authors' main aim was to extend previous findings to the general population and to a younger age group. A secondary aim was to explore the role of feelings of loneliness referring to the previous link. A sociocognitive understanding task followed by self-report questionnaires on depressive symptoms and perceived loneliness were administered to a sample of 326 students attending primary and middle schools. Mediation analyses revealed that feelings of loneliness mediated the effect of sociocognitive understanding on depressive symptoms, but only among girls. In boys, depressive symptoms were directly linked to sociocognitive skills. In girls, on the contrary, the relationship between sociocognitive skills and depressive symptoms was significantly mediated by feelings of loneliness. Theoretical and practical implications of these findings are discussed.     

Can pictures promote the acquisition of sight‐word reading? An evaluation of two potential instructional strategies

Sight‐word instruction can be a useful supplement to phonics‐based methods under some circumstances. Nonetheless, few studies have evaluated the conditions under which pictures may be used successfully to teach sight‐word reading. In this study, we extended prior research by examining two potential strategies for reducing the effects of overshadowing when using picture prompts. Five children with developmental disabilities and two typically developing children participated. In the first experiment, the therapist embedded sight words within pictures but gradually faded in the pictures as needed using a least‐to‐most prompting hierarchy. In the second experiment, the therapist embedded text‐to‐picture matching within the sight‐word reading sessions. Results suggested that these strategies reduced the interference typically observed with picture prompts and enhanced performance during teaching sessions for the majority of participants. Text‐to‐picture matching also accelerated mastery of the sight words relative to a condition under which the therapist presented text without pictures.
