小学生阅读迁移机制的初步研究--字词表征还是内容表征

探讨文章字词与内容在小学生篇章阅读迁移中的作用。结果发现,阅读水平和阅读条件均对阅读迁移效果有显著主效应。阅读水平低的被试的阅读准确性提高得更大;完全重复条件和词汇重复条件在阅读时间和准确性上都没有显著差异,完全重复条件下的阅读时间和准确性均比意义重复及无相关条件的阅读时间和准确性提高得更多;词汇重复条件下的阅读时间和准确性显著高于意义重复条件下的成绩;词汇相同的阅读准确性也显著高于无相关条件下的阅读准确性。据此,我们可以初步得出小学生的篇章阅读迁移主要依赖词汇表征,即词汇表征是小学生篇章阅读迁移的主要机制。     

阅读多策略使用类型对阅读成绩的影响——基于潜在剖面分析

本研究以18299名六年级学生为研究对象,通过潜在剖面分析和方差分析,探讨了六年级学生阅读多策略使用类型的潜在异质性及其对阅读成绩的影响,结果显示:(1)六年级学生的阅读多策略使用存在3个类别:熟练使用型(占36.35%),基本掌握型(占49.29%),有待提升型(占14.36%);(2)3类学生在2类文本(文学类和信息类)和4种阅读能力(分析与整合、获取与解释、连接与推论、感悟与评价)上的阅读成绩均为:属于熟练使用型的六年级学生最好,属于基本掌握型的六年级学生次之,属于有待提升型的六年级学生最差。研究结果表明对学生开展阅读多策略使用的指导非常重要。     

颜色交替文本促进小学高年级聋生篇章阅读的眼动研究

聋生由于听力损失,导致其在阅读方面存在一定的困难。如何提高聋生的阅读效率是一个具有重要的实践价值的课题。本研究采用眼动追踪技术,以29名小学高年级聋生为研究对象,考察颜色交替词标记形式对小学高年级聋生篇章阅读的促进作用。结果发现,无论是眼动指标的整体分析还是局部分析,均支持颜色交替词标记文本可以有效地提高小学高年级聋生的语篇阅读效率。本研究结果对于训练提高小学高年级聋生的阅读效率具有一定的启发意义。     

Letter Position Coding with Fred Astaire: Inversion of Letter Position Substitution Effects in Reverse Spelled Words

The effects of letter substitutions have been linked to their position within a word (letter position effects). The current study expanded upon previous research by examining letter-position effects for letter substitutions using forward- and reverse-spelled word primes. Often substituting a letter on one side of a word will have a stronger impact on performance than substituting a letter on the other side of a word. In three experiments it was revealed that the letter-position effects of substitutions changed places when words were spelled backwards. This occurred when both the target and prime were spelled backwards. This was evidence of a congruency effect of letter-position priming. The ramifications of these results for word recognition and transfer are discussed. However, the need for future research should focus on the possibility of an inversion process/mechanism.     

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.     

中文阅读中预视阶段和注视阶段内词汇视觉编码的过程特点:来自消失文本的证据

研究采用消失文本范式考察中文阅读中双字词汇视觉信息编码的过程特点。实验一操控词n+1上字词消失方式及其延迟时间,结果发现,注视词n时,词n+1上不同位置的汉字及时消失(延迟时间为0 ms)都影响总阅读时间,且影响程度与消失汉字的具体位置与消失汉字的数量有关;延迟时间为60 ms时,词n+1上的左侧字消失不再影响总阅读时间,而词n+1上的右侧字消失仍会影响总阅读时间。实验二操控词n上字词消失方式及其延迟时间,结果发现,注视词n时,词n上不同位置的汉字及时消失对总阅读时间的影响程度完全一致,说明词n上汉字视觉编码不受消失汉字的具体位置与消失汉字的数量的调节;延迟时间为60 ms时,各消失条件都不影响总阅读时间,说明词n上不同汉字的视觉编码同时完成。基于两项实验结果可得出,在预视阶段内中文读者以汉字单元编码内双字词汇的视觉信息,在注视阶段内以整词为单元编码双字词汇的视觉信息。     

绕口令效应对汉语阅读影响的眼动研究

绕口令效应指无论朗读还是默读,绕口令的阅读时间都长于正常句子的阅读时间。本研究采用Eyelink 2000型眼动仪,通过两个实验考察汉语阅读中的绕口令效应及其对知觉广度的影响。实验1结果表明:与阅读非绕口令相比,绕口令的阅读时间和注视次数均显著增加而阅读速度和平均眼跳幅度均显著下降。实验2结果表明:绕口令的知觉广度为注视点右侧1~2个汉字,控制句的知觉广度为注视点右侧2~3个汉字。结果说明汉语中存在绕口令效应,使读者知觉广度变小,阅读效率下降。。     

Masked form priming is moderated by the size of the letter-order-free orthographic neighbourhood

University students made lexical decisions to targets preceded by masked primes. In Experiment 1, transposed-letter primes were used also in the sandwich priming paradigm, in which the target is briefly pre-presented prior to the prime. The priming effects in the masked paradigm, but not in the sandwich paradigm, were moderated by the density of the letter-order-free neighbourhood of the target. In Experiment 2, letter-order-free neighbour prime words produced a priming cost in masked priming. These results are consistent with the idea that sandwich priming attenuates letter-order-free neighbour competition in target identification. Unexpectedly, no priming cost was produced by conventional (letter-position-preserving) word neighbour primes. Order-free neighbours may produce facilitation of target processing less, and more variably, than conventional neighbours.
