8─11个月婴儿迂回行为发展特点与学习能力的研究

采用程序标准化的婴儿迂回行为测验,探讨了２４４名８─１１个月婴儿的迂回行为发展特点及学习能力。结果表明：（１）８─１１个月婴儿的迂回行为水平表现出随婴儿月龄的增长而提高的趋势。（２）８─１１个月的婴儿具有从反复尝试中学会迂回行为的可能性,其中９、１０个月婴儿的学习可能性较大,而８个月婴儿的学习可能性较小。（３）８──１１个月婴儿的学习速度随月龄增大而提高     

同伴排斥与青少年早期饮酒行为:同伴侵害和不良同伴的中介效应

采用同伴提名、同伴侵害问卷、不良同伴问卷和饮酒行为问卷调查广东地区4所普通初级中学1386名7年级学生,考察了同伴排斥与青少年早期饮酒行为的关系,以及同伴侵害和结交不良同伴在其中的链式中介效应。结果发现:(1)同伴排斥、同伴侵害和结交不良同伴均与青少年早期的饮酒行为呈显著正相关;(2)同伴侵害和结交不良同伴在同伴排斥影响青少年早期饮酒行为过程中的链式中介效应显著,即同伴排斥通过增加同伴侵害,从而提高结交不良同伴的风险,进而增加青少年早期的饮酒行为;(3)在控制同伴侵害和结交不良同伴后,同伴排斥对青少年早期的饮酒行为仍存在显著预测作用。

Using support vector machines to identify literacy skills: Evidence from eye movements

Is inferring readers’ literacy skills possible by analyzing their eye movements during text reading? This study used Support Vector Machines (SVM) to analyze eye movement data from 61 undergraduate students who read a multiple-paragraph, multiple-topic expository text. Forward fixation time, first-pass rereading time, second-pass fixation time, and regression path reading time on different regions of the text were provided as features. The SVM classification algorithm assisted in distinguishing high-literacy-skilled readers from low-literacy-skilled readers with 80.3 % accuracy. Results demonstrate the effectiveness of combining eye tracking and machine learning techniques to detect readers with low literacy skills, and suggest that such approaches can be potentially used in predicting other cognitive abilities.     

Levels of phonological awareness in three cultures

This study focused on syllable phoneme onset levels of phonological awareness in relation to reading of Chinese and English in kindergarten and first-grade children from Xian (China), Hong Kong, and Toronto, cultures that differ substantially in approaches to reading instruction. English syllable awareness among native Chinese speakers was as good as or better than that among English speakers, indicating that the Chinese language may promote syllable-level awareness in children. Hong Kong children recognized significantly more words in both English and Chinese but were significantly poorer than the Xian children in both syllable and phoneme onset deletion tasks, suggesting that Pinyin training (given in Xian only) may promote phonological awareness even at the syllable level. In both Xian and Hong Kong, measures of syllable awareness consistently predicted Chinese character recognition better than did phoneme onset awareness. In contrast, English word recognition was predicted differently by syllable and phoneme onset awareness across cultures. These results underscore the roles of both language and writing system in understanding levels of phonological awareness.     

Event‐related potentials reveal linguistic suppression effect but not enhancement effect on categorical perception of color

The present study used the event‐related potential technique to investigate the nature of linguistic effect on color perception. Four types of stimuli based on hue differences between a target color and a preceding color were used: zero hue step within‐category color (0‐WC); one hue step within‐category color (1‐WC); one hue step between‐category color (1‐BC); and two hue step between‐category color (2‐BC). The ERP results showed no significant effect of stimulus type in the 100‐200 ms time window. However, in the 200–350 ms time window, ERP responses to 1‐WC target color overlapped with that to 0‐WC target color for right visual field (RVF) but not left visual field (LVF) presentation. For the 1‐BC condition, ERP amplitudes were comparable in the two visual fields, both being significantly different from the 0‐WC condition. The 2‐BC condition showed the same pattern as the 1‐BC condition. These results suggest that the categorical perception of color in RVF is due to linguistic suppression on within‐category color discrimination but not between‐category color enhancement, and that the effect is independent of early perceptual processes.
