高低阅读技能聋生词汇加工的语境预测性效应特点:眼动证据

本研究考察中文聋生读者利用语境预测性信息促进词汇加工的过程特点。实验采用3（组别：高阅读技能聋生组vs.高阅读技能聋生的能力匹配健听组vs.低阅读技能聋生组）×2（句子背景对目标词的预测程度：高预测vs.低预测）混合设计。结果发现：（1）目标词的左侧词汇上,能力匹配健听组在凝视时间和总注视时间两个指标上可见语境预测性效应,两个聋生组在任何指标上均没有语境预测性效应;（2）目标词上,能力匹配健听组在首次注视时间、凝视时间和总注视时间三项指标上均可见显著的语境预测性效应,高阅读技能聋生组仅在总注视上可见语境预测性效应,低阅读技能聋生的任何眼动指标均没有语境预测性效应。由此可见,聋生在利用语境预测性促进词汇加工方面与健听读者有所差异;相对于低阅读技能聋生,高阅读技能聋生读者识别词汇时能更多地利用语境预测性信息。     

词汇预测性对中文高、低阅读技能儿童眼动行为的影响

操纵目标词的预测性、词频和阅读技能水平,考察句子阅读中词汇预测性对高、低阅读技能儿童眼动行为的影响,揭示其在儿童阅读发展中的作用。结果显示：儿童对高预测词的跳读率更高、注视时间更短,且预测性与词频交互影响跳读率和注视时间;预测性对高阅读技能儿童早期的跳读率影响更大,而对低阅读技能儿童晚期的再阅读时间具有更大影响。结果表明：词汇预测性影响儿童阅读的眼动行为和词汇加工,且作用大小和发生时程受阅读技能调节。     

The effect of a virtual reality environment on gaze behaviour and motor skill learning

ObjectiveVirtual reality (VR) systems hold significant potential for training skilled behaviours and are currently receiving intense interest in the sporting domain. They offer both practical and pedagogical benefits, but there are concerns about the effect that perceptual deficiencies in VR systems (e.g. reduced haptic information, and stereoscopic display distortions) may have on learning and performance. ‘Specificity of learning’ theories suggest that VR could be ineffective (or even detrimental) if important differences (e.g. perceptual deficiencies) exist between practice and real task performance conditions. Nevertheless, ‘structural learning’ theories suggest VR could be a useful training tool, despite these deficiencies, because a trainee can still learn the underlying structure of the behaviour. We explored these theoretical predictions using golf putting as an exemplar skill.MethodIn Experiment 1 we used a repeated measures design to assess putting accuracy (radial error) and quiet eye duration of expert golfers (n = 18) on real putts before and after 40 VR ‘warm up’ putts. In Experiment 2, novice golfers (n = 40) were assigned to either VR or real-world putting training. Putting accuracy and quiet eye durations were then assessed on a real-world retention test.ResultsBoth visual guidance (quiet eye) and putting accuracy were disrupted temporarily when moving from VR to real putting (Experiment 1). However, real-world and VR practice produced comparable improvements in putting accuracy in novice golfers (Experiment 2).ConclusionOverall, the results suggest that: (i) underlying skill structures can be learned in VR and transferred to the real-world; (ii) perceptual deficiencies will place limits on the use of VR. These findings demonstrate the challenges and opportunities for VR as a training tool, and emphasise the need to empirically test the costs and benefits of specific systems before deploying VR training.

Response inhibition in motor and oculomotor conflict tasks: Different mechanisms,different dynamics?

Previous research has shown that the appearance of task-irrelevant abrupt onsets influences saccadic eye movements during visual search and may slow down manual reactions to target stimuli. Analysis of reaction time distributions in the present study offers evidence suggesting that top-down inhibition processes actively suppress oculomotor or motor responses elicited by a salient distractor, in order to resolve the conflict that arises when reflex-like and deliberate responses are in opposition. Twenty-six participants carried out a variation of the oculomotor capture task. They were instructed to respond with either a saccade toward or with a button press at the side of the hemifield in which a target color singleton appeared. A distractor stimulus could appear either in the same or in the opposite hemifield. Delta plots revealed competition between reflex-like and deliberate response activation, and highlighted selective inhibition of automatic responses: While participants generally responded more slowly in incongruent compared to congruent situations, this effect diminished and even reversed in the slowest speed quantiles. These effects were present in both the oculomotor and motor response-mode conditions.     

消失文本条件下词的预测性效应的眼动研究

通过考察消失文本条件下的词的预测性效应,探讨影响中文阅读眼动模式的控制因素,为中文阅读的眼动控制理论提供实证证据。以28名大学生为被试,在被试阅读实验句的同时记录其眼动轨迹。被注视的词的呈现时间设为80ms,在这种特殊的实验情境下,考察中文阅读眼动模式的影响因素。以词的预测性为自变量,以被试对目标词的首次注视时间、凝视时间和总注视时间为因变量。结果发现,在消失文本条件下,出现了显著的预测性效应。结果支持眼动的认知控制模型。     

位置和内容对网页广告效果影响的眼动评估

使用TobiiT120型眼动仪,以16名大学生为被试,记录他们阅读嵌有网页广告新闻网页时的眼动注视过程,以探讨广告呈现位置、新闻内容与网页广告的相关性是否影响人们对网页广告的注视。实验采用3（广告位置：上方、中间、下方）×2（相关性：相关、不相关）两因素被试内设计。结果发现：（1）新闻内容和网页广告的相关性不影响人们对网页广告的加工;（2）对位于新闻上方和新闻中间的网页广告,被试的注视次数较多,且注视时间较长;（3）对位于新闻中间的网页广告,其再认效果优于位于新闻上方和新闻下方的广告。表明只有网页广告呈现位置这一因素影响被试对网页广告的注视。     

当代国际传教运动研究的“四个跨越”

20世纪60年代尤其是冷战结束以来,宗教在全世界范围迅速增长,各种跨国宗教运动和现象风起云涌,其中国际传教运动的突飞猛进尤为引人注目,这不仅在很大程度上改变了世界宗教布局,而且对人们关于传教运动的传统看法和理论范式形成了具有颠覆性的挑战。本文主要针对当前国际传教运动的发展趋势和国内学界对传教运动尤其是基督教传教运动研究的现状,提出"国际视野、当代关怀"以及实现"四个跨越"的研究设想,以对全球宗教复兴作更加全面的学术回应。

道路交通标志中对称结构效应的眼动研究

本研究考察了道路交通标志中路名信息对称结构效应的眼动模式。实验采用眼动跟踪技术和视觉搜索范式,共有16名被试参加。实验结果表明：（1）在对称结构路名信息的视觉搜索中,被试的反应正确率明显优于非对称结构条件下的正确率;（2）对称结构条件下,被试的注视点和回扫次数明显较少,凝视时间明显较短;（3）在以道路交通标志为视觉搜索材料时,搜索区有无路名目标对视觉搜索绩效没有影响。可以认为：在道路交通标志中存在对称结构效应;眼动模式的差异是引起对称结构效应的认知机制。
