The effects of grammatic class and cue type on cueing responsiveness in aphasia

This study investigated the effects of two types of cues (semantic and phonemic) and two grammatic classes (noun and verb) on cueing responsiveness. Subjects consisted of 10 Broca's, 10 Wernicke's, 8 conduction, and 8 anomic aphasics. Cues were administered following failure to name on confrontation. Responsiveness to the two types of cues was dependent on aphasic type and grammatic class. Broca's and conduction aphasics responded better to phonemic cueing, while anomic aphasics were more responsive to semantic cueing. With regard to grammatic class, aphasics responded better to phonemic cueing on nouns; however, no significant difference between types of cues was demonstrated on verbs. Neuropsychological implications for the cueing and naming processes are discussed.     

鄂西南天主教传播及其现代变迁

本文通过民族学田野调查方法介绍了天主教在湖北利川传播的历史渊源及其演变,分析了天主教在土家族山区得以传播的原因,阐述了天主教传播现代变迁的特点,认为天主教在当代土家族地区的传播强度逐步削弱,信徒对天主教的信仰趋于理性。     

派遣制员工对雇用形式的认知与其工作态度的关系研究

采用派遣制员工对雇用形式的认知等5项问卷,对270名派遣制员工进行测查。结果发现:(1)派遣制员工组织认同、工作投入和工作满意度均处较高水平,离职倾向相对较低。(2)78.9%知道自已的派遣制身份;33.1%愿意作为派遣制员工;对于派遣制存在模糊认识和矛盾心态。(3)知道派遣制身份者组织认同、工作奉献、工作意义和工作乐趣等显著高于不知道者;愿意作为派遣制员工者工作满意度、工作意义和工作奉献显著高于不愿意者。对雇用形式的认知在一定程度上决定派遣制员工的工作态度。     

Facile route to synthesising mesoporous SBA-15 using phosphoric acid

A facile route has been developed to synthesise mesoporous SBA-15 using mild H₃PO₄ (replacing the most commonly used strong acid HC1) as the medium and the effects of H₃PO₄ concentration and synthesis temperature on the mesostructure and morphology of the resultant materials investigated. The results demonstrate that a more ordered structure can be obtained at low H₃PO₄ concentration (1–2?M), while a higher H₃PO₄ concentration (3–4?M) results in a less ordered structure. Furthermore, the morphology of SBA-15 particles transforms from rod-like to sphere-like with increasing H₃PO₄ concentration.     

The resilience status of Chinese left-behind children in rural areas: a meta-analysis

The resilience has become the main trend of the left-behind children's (LBC) mental health research. To evaluate the resilience status of Chinese LBC in rural areas, a meta-analysis was performed. Relevant studies were identified using electronic databases from 1990 to 2017. Pooled weighted mean difference (WMD) and 95% confidence interval (95% CI) were calculated with fixed and random effects models. A total of 14 cross-sectional studies with 9777 individuals were included in this meta-analysis. The results showed there was significant difference in the aspects of family support and RSCA (Resilience Scale for Chinese Adolescents) total score between LBC and non-left-behind children (NLBC). After stratification subgroup, significant difference in RSCA total score was also found in subgroup with sample size ≥700 and target population (LBC) between LBC and NLBC. In addition, there was no significant difference in resilience of male and female among LBC (P >0.05). We also found RSCA total score of LBC whose one parents migratingwere higher than both parents (P <0.05) and the time of parental migration (≤2 years) were higher than others (>2 years). In conclusion, more attention should be paid to the LBC, especially both parents migrating or parental migration (>2 years).     

Effects of Phonetic Similarity in the Identification of Mandarin Tones

Tonal languages differ in how they use phonetic correlates e.g. average pitch height and pitch direction, for tonal contrasts. Thus, native speakers of a tonal language may need to adjust their attention to familiar or unfamiliar phonetic cues when perceiving non-native tones. On the other hand, speakers of a non-tonal language may need to develop sensitivity to tonal correlates absent from their native system. The current study examines and compares five language groups’ perception of two synthesized Mandarin tones: the high level tone and the high falling tone. It aims to examine how listeners from tonal and non-tonal backgrounds identify and categorize acoustically equidistant pitches varying along two phonetic dimensions: pitch onset and slope. Results reveal “universal” perceptual patterns across groups and also tendencies caused by native tonal systems. Our findings confirm that L1 tonal and prosodic systems affect speakers’ sensitivity to novel perceptual cues and their abilities to discern relevant phonetic differences.     

因果关系及典型性程度对类别特征推理的影响

采用学习―测试二阶段实验范式,探讨了因果关系及典型性程度对类别特征推理的影响。研究结果表明:(1)因果关系影响类别特征推理任务;(2)典型性程度影响类别特征推理任务;(3)类别特征间存在因果关系的前提下,原因特征维度值与典型性程度间存在交互作用。典型性程度对不含原因特征的项目的特征推理影响是有限的。     

词汇获得年龄在物体和动作图画命名中的不同作用

本研究目的是考察词汇获得年龄(早与晚)这一因素对物体图画和动作图画命名是否产生了不同的影响。采用物体图画和动作图画命名任务,发现:(1)相比于物体图画命名,动作图画命名的反应时更长,表明动词的产生更为复杂。(2)在物体图画命名任务中,与晚获得词相比,早获得的词产生速度更快;相比而言,在动作图画命名中,晚获得词比早获得词的反应时更短,反应速度更快。基于分析和讨论,我们认为Ao A效应可能发生在图画命名过程中的词汇水平,而非概念水平或反应输出阶段。     

汉语声调对称规则的内隐学习及变异性效应

关于内隐学习能否获得底层的抽象规则,研究一直存在争议。该研究通过有效地控制组块和重复结构等表面特征,并操纵规则所在背景的变异性大小,考察了两种汉语声调对称规则——逆行和倒映的内隐学习。结果发现,只有在背景变异较大时,被试才能够超越组块等表面特征,进而无意识地获得汉语声调对称规则的结构知识。该研究证明内隐学习能够获得抽象规则,并从背景变异性效应的角度为考察该问题提供了新的视角。
