Improving Children's Mental Rotation Accuracy With Computer Game Playing

The authors investigated the relation between mental rotation (MR) and computer game-playing experience. Third grade boys (n = 24) and girls (n = 23) completed a 2-dimensional MR test before and after playing computer games (during 11 separate 30-min sessions), which either involved the use of MR skills (the experimental group) or did not involve the use of MR skills (the control group). The experimental group outperformed the control group on the MR posttest but not on the pretest. Boys outperformed girls on the pretest but not on the posttest. Children whose initial MR performance was low improved after playing computer games that entailed MR skills. The findings imply that computer-based instructional activities can be used in schools to enhance children's spatial abilities.     

心理旋转中的性别差异

性别差异是认知心理学中一个重要的研究领域。男性在执行空间认知任务时的表现往往好于女性,在心理旋转任务中,这种现象更为普遍。近年来,人们在行为和脑成像等层面对心理旋转中的性别差异进行了大量的研究,该文通过对其中一部分研究的回顾描述了心理旋转的性别差异在行为及脑成像实验中的表现,总结了可能导致这种性别差异的生理及策略等因素

Mental Rotation in False Belief Understanding

This study examines the spontaneous use of embodied egocentric transformation (EET) in understanding false beliefs in the minds of others. EET involves the participants mentally transforming or rotating themselves into the orientation of an agent when trying to adopt his or her visuospatial perspective. We argue that psychological perspective taking such as false belief reasoning may also involve EET because of what has been widely reported in the embodied cognition literature, showing that our processing of abstract, propositional information is often grounded in concrete bodily sensations which are not apparently linked to higher cognition. In Experiment 1, an agent placed a ball into one of two boxes and left. The ball then rolled out and moved either into the other box (new box) or back into the original one (old box). The participants were to decide from which box they themselves or the agent would try to recover the ball. Results showed that false belief performance was affected by increased orientation disparity between the participants and the agent, suggesting involvement of embodied transformation. In Experiment 2, false belief was similarly induced and the participants were to decide if the agent would try to recover the ball in one specific box. Orientation disparity was again found to affect false belief performance. The present results extend previous findings on EET in visuospatial perspective taking and suggest that false belief reasoning, which is a kind of psychological perspective taking, can also involve embodied rotation, consistent with the embodied cognition view.     

Higher Processes in Motor Learning

A linear displacement task was used to study the effects of post-KR verbal activity and the time of its introduction in the learning process on the acquisition of a simple discrete motor task. The temporal occurrence of the interpolated act was systematically varied (3 and 10 sec. immediately following KR). Reading polysyllables during the post-KR delay interval interfered with the learning process. Interference occurred whether the post-KR delay interval lasted 3 or 10 sec.     

儿童数字估计中的心理长度

从儿童对数字属性的认识角度探讨一年级儿童在不同数字范围中采用不同表征形式的根本原因。两个实验均采用数字线估计任务,实验一测量一年级儿童在15cm数字线长度下0～100与0～1000两种范围上的数字估计;实验二测量一年级儿童对0～1000范围10cm和20cm数字线长度的估计。结果显示,无论在不同的数字范围还是在不同的数字线长度下,儿童对低端数字的估计均存在心理长度,即儿童倾向于将低端数字与固定的线段长度对应起来,且这种对应关系不随数字范围与数字线长度的变化而变化。心理长度的存在是儿童在不同数字范围和不同数字线长度中采用不同数字表征形式的根本原因,也是儿童对数概念的认识发展到等距水平时出现的一种独特特点。     

Two Routes to Expertise in Mental Rotation

The ability to imagine objects undergoing rotation (mental rotation) improves markedly with practice, but an explanation of this plasticity remains controversial. Some researchers propose that practice speeds up the rate of a general‐purpose rotation algorithm. Others maintain that performance improvements arise through the adoption of a new cognitive strategy—repeated exposure leads to rapid retrieval from memory of the required response to familiar mental rotation stimuli. In two experiments we provide support for an integrated explanation of practice effects in mental rotation by combining behavioral and EEG measures in a way that provides more rigorous inference than is available from either measure alone. Before practice, participants displayed two well‐established signatures of mental rotation: Both response time and EEG negativity increased linearly with rotation angle. After extensive practice with a small set of stimuli, both signatures of mental rotation had all but disappeared. In contrast, after the same amount of practice with a much larger set both signatures remained, even though performance improved markedly. Taken together, these results constitute a reversed association, which cannot arise from variation in a single cause, and so they provide compelling evidence for the existence of two routes to expertise in mental rotation. We also found novel evidence that practice with the large but not the small stimulus set increased the magnitude of an early visual evoked potential, suggesting increased rotation speed is enabled by improved efficiency in extracting three‐dimensional information from two‐dimensional stimuli.

心理旋转的角色效应研究

本研究采用2×4混合实验设计,通过对旋转类型和旋转角度的控制,探讨第一人称角色和第三人称角色心理旋转的差异性。实验结果表明,空间表征转换的角色方式是影响心理旋转的重要因素,第三人称角色心理旋转易于第一人称角色心理旋转。     

想象空间心理旋转的角色效应

第一人称角色心理旋转和第三人称角色心理旋转是人类视觉系统通常采用的两种不同的空间表征动力转换策略。该研究采用实验方法,对违背物理移动规律的两种角色水平面心理旋转进行对比性研究。实验结果表明,想象空间两种角色水平面心理旋转存在显著差异,第三人称角色心理旋转的优势可概括化于旋转轴物理方向与重力方向不一致的水平面心理旋转中。     

不同平面心理旋转的角色效应

Phonemic Processes in Children's Listening and Reading Comprehension

Two experiments were conducted to investigate the role of phonemic activation in children's listening and reading comprehension. Phonemically confusing stories were presented in a listening comprehension task to kindergarten and second-grade children and in a reading comprehension task to second-grade children only. Rhymes induced phonemic confusion more consistently than did alliteratives in both the listening and reading tasks at both grade levels, suggesting that rhyme is inherently more confusing than alliteration, and furthermore, that phonemic information is activated in similar ways when children listen and when they read silently. Children's reading skill was also assessed to examine a possible relationship between reading skill and phonemic sensitivity, but no significant interactions between children's reading skill and their sensitivity to phonemic confusion were found in the reading task. In the listening task, all groups showed phonemic confusion in gist recall scores, but prereaders were less likely than readers to exhibit susceptibility to phonemic confusion in verbatim recall scores.     

同时线索化条件下儿童返回抑制的容量

返回抑制是对先前注意过的目标再次做出反应的时候反应时延长的一种现象。返回抑制具有一定的生物学意义,忽略已经注意过的位置(或客体),使得有机体可以更加有效的注意新的内容。基于这一点,返回抑制现象应该可以在多个已经注意过的位置出现,这便是返回抑制的容量问题。在本研究中,采用同时呈现的线索化方式,考查8岁、10岁儿童在不同的实验任务——觉察任务和辨别任务——中的返回抑制容量。结果发现觉察任务中,10岁组儿童和8岁组儿童最多在5个线索化位置上出现返回抑制,但8岁年龄组的返回抑制容量缺乏稳定;辨别任务中,10岁年龄组只在一个位置上出现返回抑制,而8岁年龄组并没有明显返回抑制现象出现。年龄因素和任务类型对儿童返回抑制容量都产生了一定程度的影响。     

Implicit Mental Processes in Ethical Management Behavior

This article examines the relationship between implicit mental processes and ethical decisions made by managers. Based on the dual-process view in social and cognitive psychology, it is argued that social cognition (e.g., moral judgments) can rely on two different modes of information processing. On one hand, moral judgments reflect explicit, conscious, and extensive cognitive processes, which are attributed to explicit attitude. On the other hand, moral judgments may also be based on implicit, automatic, and effortless processes referring to implicit attitude. To test this thesis, a study involving 182 participants was conducted. The results support the thesis.     

物体识别的视角依赖与心理旋转

物体识别的绩效随物体的视角变化而变化,这一物体识别的视角依赖现象引发了研究者对物体识别的机制的广泛讨论。有研究者认为,心理旋转是导致物体识别视角依赖的原因,而另一种观点认为物体识别中不包含心理旋转过程。两种观点都有来自于行为和神经机制两方面研究的证据。然而,现有的行为证据都是间接的证据,缺乏说服力。进一步的研究应注重直接操纵影响心理旋转与物体识别过程的因素,并把行为研究与能进行实时监测的眼动、脑成像等研究结合起来     

双任务情境下心理旋转的并行加工机制

采用心理不应期研究范式,三个反应时实验检测了心理旋转任务和其他认知操作任务能否并行加工的问题。在每个实验中要求被试快速、系列地完成对高低音的辨别任务(T1)和不同旋转角度的正反像辨别任务(T2),T1和T2呈现的时间间隔运用变化的SOA。结果发现：(1)T1的反应选择对T2的反应选择产生了很大的影响,在T2上PRP效应显著。心理旋转的操作成绩随着SOA的缩短而降低。(2)在T1上同样存在随着SOA缩短,反应时增加,正确率下降的趋势。T2的反应选择对T1的反应选择同样产生了显著的影响。(3)T2的反应选择对T1的中枢加工产生了相应的影响,表明当T1的反应选择占据中枢瓶颈时,心理旋转任务和其他认知操作任务在中枢瓶颈中并行得到了有效的加工     

儿童对道义情景中的心理状态的推理

该文回顾了儿童对道义情景中心理状态推理的研究,包括儿童对行为者愿望、信念和情绪的推理以及对权威愿望的推理研究。总体来讲,道义规则的引入使得儿童过分根据道义规则来对行为者的行为和心理状态进行推理,但是不同的研究还存在诸多矛盾之处,这可能与以往的研究中所使用的道义规则属于不同的领域（如道德、习俗及防范等领域）以及实验任务（如行为预测和奖惩判断等）的差异有关。最后该文提出另外两个可能的影响因素：道义规则的形式和儿童的视角采择能力     

自我和物体为参照系的心理旋转分离：内旋效应

采用虚拟的旋转不同角度左、右手模型,构建“左右手判断(Left and right hand judgment: LR)”任务和“相同－不同判断(same and different judgment: SD)”任务,考察这两种实验任务是否都存在内旋效应和角度效应,以此推论被试采用何种旋转策略。结果发现：（1） 两种实验任务结果均表现出显著的角度效应。（2）在LR任务条件下,存在显著的内旋效应,而在SD任务中不存在内旋效应。从而表明当人手图片作为心理旋转材料时,它具有双重角色。被试心理旋转加工时究竟选用何种参照系的旋转策略,与实验材料和实验任务两者都密不可分
