场景知觉中的眼动分析指标:基于注视和眼跳视角

眼动范式是场景知觉研究的重要方法之一,可以通过对场景知觉过程中眼动变化的实时记录,真实地反映场景信息加工的内在心理机制;然而,人们的心理活动是极其复杂的,与之相应的眼动指标也具有多样性和复杂性。对眼动指标的分析,有不同的分析维度,比如整体和局部、时间和空间等。本文回顾了已有的眼动指标分类,并尝试从注视和眼跳的视角对场景知觉过程中的眼动指标进行分类。在此基础上,从界定标准、心理学意义、研究应用等方面对相应的眼动指标进行分析和介绍,最后提出了眼动指标分析和应用可能存在的问题,以及未来研究可能拓展的领域。     

SWIFT-Ⅱ：阅读中眼跳发生的动力学模型

文章阐述了SWIFT模型的最新进展—SWIFT-Ⅱ模型的基本观点。SWIFT-Ⅱ模型能够在更为详细的水平上分析模型的模拟结果,也较好地解释了词长和词频效应、注视时间的分布、回视、再注视、初次登陆位置等眼动现象。最后对SWIFT-Ⅱ模型与E-ZReader模型进行了比较。     

Computational Evidence That Frequency Trajectory Theory Does Not Oppose But Emerges From Age‐of‐Acquisition Theory

According to the age‐of‐acquisition hypothesis, words acquired early in life are processed faster and more accurately than words acquired later. Connectionist models have begun to explore the influence of the age/order of acquisition of items (and also their frequency of encounter). This study attempts to reconcile two different methodological and theoretical approaches (proposed by Lambon Ralph & Ehsan, 2006 and Zevin & Seidenberg, 2002 ) to age‐limited learning effects. The current simulations extend the findings reported by Zevin and Seidenberg (2002) that have shown that frequency trajectories (FTs) have limited and specific effects on word‐reading tasks. Using the methodological framework proposed by Lambon Ralph and Ehsan (2006) , which makes it possible to compare word‐reading and picture‐naming tasks in connectionist networks, we were able to show that FT has a considerable influence on age‐limited learning effects in a picture naming task. The findings show that when the input–output mappings are arbitrary (simulating picture naming tasks), the links formed by the network become entrenched as a result of early experience and that subsequent variations in frequency of exposure of the items have only a minor impact. In contrast, when the mappings between input‐output are quasi‐systematic or systematic (simulating word‐reading tasks), the training of new items was generalized and resulted in the suppression of age‐limited learning effects. At a theoretical level, we suggest that FT, which simultaneously takes account of time and the level of exposure across time, represents a more precise and modulated measure compared with the order of introduction of the items and may lead to innovative hypotheses in the field of age‐limited learning effects.     

内隐序列学习表征机制探究：眼动证据

内隐序列学习的表征机制是内隐学习研究领域的基本问题, 还存在争议。采用眼动追踪技术, 通过3个实验探讨内隐序列学习的表征机制。结果发现, 知觉序列混合眼跳和反应序列混合眼跳条件下发生序列学习; 朝向眼跳和反向眼跳条件下发生序列学习; 有、无分心反向眼跳下发生序列学习, 两者序列学习量差异不显著。整个研究表明, 内隐序列学习的表征依赖于序列信息。     

国内追踪数据分析方法研究与模型发展

追踪研究因其可以得到比横断研究更有说服力的变量关系论证, 在心理学等科学中具有重要地位。梳理国内以心理学为主的相关领域中追踪数据分析方法研究的发表现状、主要解决的研究问题和模型发展。追踪研究可以进行均值差异比较、分析多变量相互影响、描述总体发展趋势及差异和探究心理动态变化过程。近20年的研究热点和发展思路也集中在上述研究问题当中, 特别是总体发展趋势及差异、多变量相互影响、总体发展趋势与多变量相互影响的融合、追踪研究设计、缺失数据等议题上。最后, 比较国内外研究的差异, 并结合交叉学科对国内追踪研究未来发展做出展望。     

Life satisfaction trajectories among junior high school students in China: The role of parent–child communication

A 3-year follow-up test (from grades 7 to 9) was administered to 807 junior high school students from two regions in Hunan Province, China, using multilevel analysis to examine trends in junior high school students' life satisfaction, differences by gender and location of life and the effects of father–child/mother–child communication on the development of life satisfaction. The results showed that (1) Chinese junior high school students' life satisfaction showed a decreasing trend from the seventh grade to the ninth grade, and there was a significant decreasing process in the eighth grade; (2) father–child communication and mother–child communication had a significant positive predictive effect on Chinese junior high school students' life satisfaction and (3) father–child communication and mother–child communication had a significant negative predictive effect on the decreasing trend of life satisfaction, in which the effect of mother–child communication was particularly significant.     

停表错觉的机制：注意是否为决定因素

通过两个实验探讨了注意是否影响停表错觉（chronostasis）。实验一要求被试在注视时或眼跳后,估计处于眼跳目标或其附近位置的刺激的持续时间;实验二要求被试在眼跳条件下辨别眼跳目标或其附近位置的刺激,以考查两种位置的注意水平。结果表明,眼跳目标位置的注意水平高于其附近位置,而两种位置均可产生停表错觉,且两者的错觉量近似相等。从而说明注意并不影响停表错觉,停表错觉的机制可能是眼跳目标及其附近刺激的知觉提前。
