The effect of self-referencing on memory for different kinds of source information

ABSTRACT

Self-referential processing has been proven to be effective in improving source memory. However, it is unclear whether different types of source information would be consistently enhanced when an item is self-referentially processed. In two experiments, the authors examined the influence of the self (compared with other-referencing and semantic processing) as well as learning intention (incidental/intentional learning) on memory for two types of source information (spatial location and colour) that differ in the amount of cognitive resources they require to be encoded in memory. Results show that self-referencing has enhanced memory for spatial location of words whatever this information is learned intentionally or incidentally, whereas it cannot facilitate memory for the colour of words under the intentional learning condition, nor can it under the incidental condition. These findings suggest that self-referential processing is beneficial in memory improvement but not all-powerful, a source self-reference effect is subject to source information type.     

On the automaticity of contingent capture: disruption caused by the attentional blink

Converging evidence has shown that onset capture can be completely eliminated by the demands of a concurrent task and during the attentional blink. In the present study, we investigated contingent capture during the attentional blink. We found that contingent capture was attenuated, or even completely eliminated, during the “blink” time of the attentional blink. These results indicate that contingent capture requires limited attentional resources.     

比较视觉搜索任务中工作记忆最小化的眼动研究

采用比较视觉搜索任务和眼动追踪技术,通过增加组成图片的图形数量和改变不同图形的特征属性,考察比较视觉搜索任务是否遵循工作记忆最小化原则以及图形特征加工的优先性问题。结果表明图形数量的增加不影响平均每次注视的图形数量,被试平均每次注视1.65个图形,即比较视觉搜索任务仍遵循工作记忆最小化原则。不同图形中颜色和形状都不同的注视时间最短,颜色不同和形状不同在注视时间上差异不显著,表明比较视觉搜索任务中特征维度数量比特征性质在引导注意上具有优先性。事先不规定搜索路径的情况下,被试主要采用系统搜索策略完成比较搜索任务。     

Backward-walking biological motion orients attention to moving away instead of moving toward

Walking direction is an important attribute of biological motion because it carries key information, such as the specific intention of the walker. Although it is known that spatial attention is guided by walking direction, it remains unclear whether this attentional shift is reflexive (i.e., constantly shifts to the walking direction) or not. A richer interpretation of this effect is that attention is guided to seek the information that is necessary to understand the motion. To investigate this issue, we examined how backward-walking biological motion orients attention because the intention of walking backward is usually to avoid something that walking forward would encounter. The results showed that attention was oriented to the walking-away direction of biological motion instead of the walking-toward direction (Experiment 1), and this effect was not due to the gaze direction of biological motion (Experiment 2). Our findings suggest that the attentional shift triggered by walking direction is not reflexive, thus providing support for the rich interpretation of these attentional effects.     

青少年重复梦主题的调查研究

该文通过对615名青少年进行《重复梦调查问卷》、梦的态度量表、幸福感指数量表等三份问卷的调查,结果发现:1)青少年重复梦的发生频率较高,86.4%的青少年做过重复梦;2)青少年重复主题的梦是最普遍的,占总数的32.4%;3)重复梦的发生频率个体差异较大,难以发现固定规律;4)重复梦里的情绪多为负性的情绪,占58.4%,其中恐惧是重复梦中体验最多的情绪,占38.0%;5)青少年重复梦发生频率最高的两大主题就是被追赶和坠落;6)是否做过重复梦与梦的态度显著相关,现在还在做重复梦的群体对梦的态度最积极;7)有没有重复梦与个体的主观幸福感指数不存在显著相关。

2岁儿童延迟性自我控制及家庭因素的相关研究

摘要研究考察2岁儿童延迟性自我控制行为的发展水平及其家庭影响因素。对86名17．5到28．5个月的儿童在画笔和食物为诱惑物的两种延迟满足情境中的行为进行实验室录像观察。同时以问卷法了解其父母教养行为、婚姻质量及亲子关系等家庭因素。结果显示：(1)2岁儿童已经具有延迟性自我控制行为．且存在性别差异。(2)家庭教养态度,尤其是母亲的教养态度对儿童自我控制行为有显著预测作用;(3)母亲所体验到的家庭生活的和谐程度能显著地预测儿童延迟性自我控制行为;(4)在控制了性别、婚姻质量及家庭教养态度后,亲子关系的作用不显著。     

隐形矫治器是否是传统矫治器的终结

牙科正畸隐形矫治技术是随着计算机革命应运而生的新型矫治技术。它与传统矫治技术相比在美观舒适和治疗预见性方面有诸多提高。最早只有AlignTechnologyInc(ALGN)这个跨国公司垄断经营,其运作方式也不同于传统矫治装置。由于它扩大了正畸患者群并面向非正畸专业的牙医出售其产品,其经营宣传已经开始影响到正畸医疗的服务格局。这样,很容易令人联想到此技术将结束传统矫治技术的时代。通过分析其时代背景和运作方式及技术局限性,认为隐形矫治器仍应作为传统矫治器的有力补充,而成为正畸学发展的助推器,而不应失去掌握着传统矫治技术的正畸医师的监控,导致盲目市场扩大化而伤害患者的健康利益。总之,隐形矫治技术不应是传统矫治技术的终结。

幼儿加减法运算中的策略发展特点

本研究随机选取北京市三所普通幼儿园小、中、大班儿童共90名,采用实物操作的非言语任务,考察3-5岁幼儿在加减法运算中的策略发展特点。结果表明:随着年龄的增长,儿童使用的策略由模仿、交换向内化、相反数策略转化;3、4岁幼儿在相反数题中,更多使用模仿和交换策略,而5岁幼儿更多使用模仿、相反数策略;在标准型题中,儿童一般较多使用模仿和内化策略;最大表征对儿童策略选择存在影响。
