学前儿童延迟满足的实验研究方法述评

延迟满足之所以能够发展成为一个相对独立的概念结构,在很大程度上取决于研究方法的突破。学前儿童延迟满足研究领域目前有三种典型的实验研究方法,即自我延迟方法、外加延迟方法和礼物延迟方法,这些研究方法对于延迟满足研究起到了十分重要的作用。但这些研究方法似乎都忽略了延迟满足过程中的一种重要的心理过程——价值评判。儿童之所以愿意忍耐长时等待,是因为他们做出了符合自己需要的选择,这一选择过程在延迟满足过程中具有重要的作用。基于延迟满足中的价值评判,尝试性地提出了对延迟满足研究方法的初步改进方案。

父亲参与对儿童延迟满足能力的影响：儿童性别的调节作用

以92名35~74个月的健康儿童为被试,采用选择等待范式测查儿童的自我延迟满足能力,通过父亲参与问卷和母亲参与教养问卷测查儿童父母的参与程度,考察控制母亲参与和儿童年龄的情况下,父亲参与对儿童延迟满足能力的影响以及儿童性别在其中的调节作用。结果表明：（1）父亲参与的互动性、可及性、责任性均能显著正向预测儿童的延迟满足能力;（2）儿童性别可以调节父亲参与的互动性及责任性与儿童延迟满足能力的关系。父亲参与的互动性和责任性可以显著预测男童的延迟满足能力,但均不能预测女童的延迟满足能力。     

4～6岁儿童直接推理能力及策略的实验研究

采用定量与定性相结合的研究方法,对4－6岁儿童的直接推理能力进行了实验研究,结果表明：（1）学前儿童萌发了评议条件下的直接推理能力,但年龄发展效应并不明显;（2）对于学前儿童而言,否定前提下的直接推理并不比肯定前提的难。但是,如果进行了反义词的转换,同样的任务,却增加了肯定前提下直接推理的任务难度,而对否定前提下的直接堆理没有影响;（3）学前儿童在直接推理时多种策略并存,随着年龄的增长,有效策略的生成能力有了明显的提高,但有效策略的使用能力并没有与有效策略的生成能力同步发展,而是表现为落后的趋势。     

儿童自我延迟满足能力发展的研究

延迟满足是一种心理成熟的表现,专指一种甘愿为更有价值的长远结果而放弃即时满足的抉择取向,以及在等待期中展示的自我控制能力。本文通过论述儿童的自我延迟满足能力的发展的特点以及影响其自我延迟满足能力的发展的因素,探索了如何教育儿童自我延迟满足能力的有效途径,对幼儿健康成长和发展具有一定的指导作用。

Expertise in pictorial perception: eye-movement patterns and visual memory in artists and laymen

In two sessions with free scanning and memory instructions, eye-movement patterns from nine artists were compared with those of nine artistically untrained participants viewing 16 pictures representing a selection of categories from ordinary scenes to abstraction: 12 pictures were made to accommodate an object-oriented viewing mode (selection of recognisable objects), and a pictorial viewing mode (selection of more structural features), and 4 were abstract. The artistically untrained participants showed preference for viewing human features and objects, while the artists spent more scanning time on structural/abstract features. A group by session interaction showed a change of viewing strategy in the artists, who viewed more objects and human features in the memory task session. A verbal test of recall memory showed no overall difference in the number of pictures remembered, but the number of correctly remembered pictorial features was significantly higher for artists than for the artistically untrained viewers, irrespective of picture type. No differences in fixation frequencies/durations were found between groups across sessions, but a significant task-dependent-group by session interaction of fixation frequency/duration showed that the artistically untrained participants demonstrated repetition effects in fewer, longer fixations with repeated viewing, while the opposite pattern obtained for the artists.     

The influence of dimensionality on eye fixations.

Eye fixation patterns were explored for sixty adult subjects, each of whom viewed one of three stimuli, either in a three-dimensional model format or in a two-dimensional photographic format. The stimuli consisted of one symmetrical and two asymmetrical color representational drawings displayed in the form of a photograph or of a model. Total fixation times (in ms) were computed for seven portions of each stimulus: top, bottom, left, right, foreground, middle ground, and background. Results indicated that for all stimuli, subjects viewing the 3-D model spent significantly more time fixating the foreground and significantly less time fixating the background than subjects viewing the 2-D photograph. For the two asymmetrical stimuli subjects in the two groups differed significantly in their fixation patterns for the left/right variables. It was concluded that eye fixation patterns vary as a function of dimensionality.     

Gaze Patterns When Looking at Emotional Pictures: Motivationally Biased Attention

Pictures of either emotionally neutral, pleasant (affectionate), or unpleasant (threat and injury) scenes were paired with nonemotional control pictures and presented for 3 s, while eye fixations were monitored. Preferential attention to the emotional picture of eah pair occurred at an early processing stage: The probability of placement of the first fixation and the proportion of viewing time during the first 500 ms were higher for both pleasant and unpleasant pictures than for neutral pictures, whereas later fixation location and time were not differentially affected. This suggests that, when emotional and nonemotional stimuli are presented simultaneously, emotional meaning captures initial overt orienting and engages attention early, as measured by gaze direction and duration. The possibility that this effect could be accounted for by perceptual differences—such as luminance and complexity—between emotional and neutral pictures was ruled out.     

Exploratory Eye Movements to Pictures in Childhood-Onset Schizophrenia and Attention-Deficit/Hyperactivity Disorder (ADHD)

We investigated exploratory eye movements to thematic pictures in schizophrenic, attention-deficit/hyperactivity disorder (ADHD), and normal children. For each picture, children were asked three questions varying in amount of structure. We tested if schizophrenic children would stare or scan extensively and if their scan patterns were differentially affected by the question. Time spent viewing relevant and irrelevant regions, fixation duration (an estimate of processing rate), and distance between fixations (an estimate of breadth of attention) were measured. ADHD children showed a trend toward shorter fixations than normals on the question requiring the most detailed analysis. Schizophrenic children looked at fewer relevant, but not more irrelevant, regions than normals. They showed a tendency to stare more when asked to decide what was happening but not when asked to attend to specific regions. Thus, lower levels of visual attention (e.g., basic control of eye movements) were intact in schizophrenic children. In contrast, they had difficulty with top-down control of selective attention in the service of self-guided behavior.     

失恋经历对爱情相关刺激注意偏向的影响:趋近还是回避?

为探讨失恋经历对爱情相关刺激注意偏向的影响,采用眼动和事件相关电位技术考察有、无失恋个体在加工积极和消极爱情信息时眼动和ERP特征。通过2个实验结果发现：在总注视时间和注视点个数眼动指标上,图片类型和失恋经历的交互作用达到统计显著水平;有失恋经历被试比无失恋经历被试对消极爱情图片的注视点更多,注视时间更长。积极爱情图片比消极爱情图片诱发的N1波峰更大,有失恋经历被试对积极图片的N1潜伏期显著快于无失恋经历的被试;有失恋经历被试在积极爱情图片上的P1波峰小于无失恋经历被试。研究表明,有、无失恋经历被试对爱情相关刺激的注意偏向存在眼动特征和神经生理上的显著差异：有失恋经历者在行为上对消极爱情图片存在注意趋近偏向,而在神经生理上对积极爱情图片存在注意回避倾向。     

自读、伴读和指读对2~3岁幼儿图画书阅读中文字注视的影响

幼儿对文字的关注是内化文字形式和功能（文字意识）的基本途径,如何有效提高年幼儿童对文字的关注是一个具有重要实践意义的课题。本研究以54名2~3岁幼儿为研究对象,记录和分析幼儿在自读、伴读和指读三种方式下阅读图画书的眼动行为。结果发现：1）自读和伴读方式下,2~3岁幼儿对文字和图画的关注具有相同的眼动模式,并且对文字的关注程度均较低;2）指读可显著提高幼儿对文字的关注频率,同时对文字注视时间、次数以及关注速度均表现出一定的促进作用;3）对图画的整体分析显示,指读与伴读/自读方式之间的眼动模式差异不显著;而进一步对图画的局部分析表明：指读不影响幼儿图画关注的全面性和有效性。综上所述,指读在一定程度上能够促进年幼儿童对文字的关注,同时动态手势也不抢占儿童阅读图画的注意资源。     

Strategic attention deployment for delay of gratification in working and waiting situations

Two studies examined whether the detrimental effects of attention to rewards on delay of gratification in waiting situations holds-or reverses-in working situations. In Study 1, preschoolers waited or worked for desired delayed rewards. Delay times increased when children worked in the presence of rewards but, as predicted, this increase was due to the distraction provided by the work itself. not because attention to rewards motivated children to sustain work. Analysis of spontaneous attention deployment showed that attending to rewards reduces delay time regardless of the working or waiting nature of the task. Fixing attention on rewards was a particularly detrimental strategy regardless of the type of task. Study 2 showed that when the work is not engaging, however, attention to rewards can motivate instrumental work and facilitate delay of gratification as long as attention deployment does not become fixed on the rewards.
