无觉知条件下的客体注意效应

采用双矩形范式变式考察在对客体无觉知的条件下的客体注意效应,共包括两个实验：实验一考察对完整矩形客体无觉知的条件下能否出现客体注意效应,发现在完整矩形客体不可见的情况下依然出现了客体注意效应。实验二考察对虚拟矩形客体无觉知的情况下是否能够出现客体注意效应,发现在虚拟矩形客体不可见的情况下也能够出现客体注意效应。研究结果表明客体注意效应在无觉知条件下依然存在,为注意与觉知在功能上相互分离的观点提供了新的证据。     

关于两项样例学习心理实验研究报告的分析与评论

对两项关于样例学习心理实验研究的报告进行了逻辑分析,指出了Ross的研究设计的合理性以及莫雷等的 “表面概貌对原理运用的影响的实验研究”中的逻辑欠缺,进而给出了莫雷等的结论“样例与作业问题表面概貌的相似性,不仅会影响原理的通达,而且也会影响原理的运用” 尚不足信的断言,所以只能继续维持Ross的“表面概貌是否相似不影响原理的运用”的结论。最后明确了莫雷等实验研究应该采取的正确设计思路和方法。     

Visual perceptual and handwriting skills in children with Developmental Coordination Disorder

ObjectiveChildren with Developmental Coordination Disorder demonstrate a lack of automaticity in handwriting as measured by pauses during writing. Deficits in visual perception have been proposed in the literature as underlying mechanisms of handwriting difficulties in children with DCD. The aim of this study was to examine whether correlations exist between measures of visual perception and visual motor integration with measures of the handwriting product and process in children with DCD.MethodThe performance of twenty-eight 8–14 year-old children who met the DSM-5 criteria for DCD was compared with 28 typically developing (TD) age and gender-matched controls. The children completed the Developmental Test of Visual Motor Integration (VMI) and the Test of Visual Perceptual Skills (TVPS). Group comparisons were made, correlations were conducted between the visual perceptual measures and handwriting measures and the sensitivity and specificity examined.ResultsThe DCD group performed below the TD group on the VMI and TVPS. There were no significant correlations between the VMI or TVPS and any of the handwriting measures in the DCD group. In addition, both tests demonstrated low sensitivity.ConclusionClinicians should execute caution in using visual perceptual measures to inform them about handwriting skill in children with DCD.     

Cognitive empathy modulates the visual perception of human-like body postures without imitation

To examine the mechanism of visual perception of human-like body postures, we conducted a posture recognition task, a questionnaire survey, and the Interpersonal Reactivity Index (IRI). The majority of participants perceived the pseudo-posture as a human posture in the early stage (78%), but only approximately half of them reported the imagination of bodily movement (66%). These results suggest that the majority of observers perceive pseudo-postures as human postures in the early stage of perception, but this human posture perception does not necessarily lead to the visualisation of bodily movement. In a group of who received the pseudo posture as a human-posture regardless of the perception stages, the participants who imagined bodily movement (64%) showed significantly higher scores than those who did not on the Fantasy subscale of the IRI. Highly empathic participants are more likely to detect a kinematic relation between the pseudo-postures.     

Linked proximal and distal changes in the reaching behavior of 5- to 12-month-old human infants grasping objects of different sizes

This study evaluates age-related proximal and distal changes in reaching organization for objects of different sizes. To this end, eight objects ranging from 2 to 9 cm diam. were presented to 23 infants ages 5 to 12 months. Proximal control was determined by the relative frequencies of bimanual reaching for large and small objects. Distal control was assessed by hand opening and orientation with respect to an object, and by the proportion of the object being included within hand opening at touch. Five-month-old infants tended to reach bimanually regardless of object size. Starting at 7 to 8 months, infants tended to reach for large objects bimanually more often than for small ones. Only at 11 to 12 months did reaching closely reflect the object’s diameter. The frequency of thumb-index finger angle opening during the approach phase also increased after 7 to 8 months of age, as well as the adjustment of the angle to the object diameter and the proportion of the object within hand opening at touch. Proximal and distal changes appeared coupled at 5 to 6 months, when the few subjects showing evidence of some proximal adjustments to object size were also those who exhibited some distal adjustments. After they started to appear, however, proximal and distal adjustments seemed to be independent, as revealed by the lack of correlation of proximal and distal changes between 7 and 12 months.     

Effects of models and demonstrations of personal narratives on the use of lexical ties by writers with mental retardation

A single subject reversal design was used to investigate the effects of two methods for teaching writing to eight adolescents with mild or moderate mental retardation during a weekly process writing workshop. During each workshop, each student wrote a personal narrative while the teacher circulated among the group and provided positive verbal feedback and spelled words on request. Students' texts were later typed with corrected spelling and punctuation and returned to them with verbal praise before the next writing workshop. During the first experimental condition, the subjects listened to an exemplar text selected by the teacher. In the second phase, the teacher read a narrative she had written as the exemplar text. During the third experimental condition, the teacher orally self-instructed herself through steps in writing a narrative. The subjects' texts were analyzed for number of words written and number and type of lexical ties used to produce cohesion between sentences in a text. The model narrative produced the best gains in the number of words written by the poorer readers, while the demonstration improved the cohesiveness of their texts. The better readers and writers wrote more cohesively during the model narrative and produced longer text during the demonstration condition.     

儿童汉字练习:纸笔手写与键盘拼音输入的效果比较

在学校情境下,采用纸笔手写和键盘拼音输入练习汉字的实验任务,比较了75名小学六年级儿童在两种练习方式下的汉字学习及复习效果,并进行了保持效果的追踪。结果发现,纸笔手写和键盘拼音输入对儿童的汉字复习具有同等积极作用,在再认选择和回忆书写上效果均相当;对儿童的汉字学习积极作用不一致:在再认选择上两者积极效果相当,但在回忆书写上,手写明显优于拼音输入。另外,经纸笔手写和键盘拼音输入复习和学习的汉字,其记忆保持随时间变化的趋势一致。以上结果说明了对具有书面语言经验的儿童,拼音输入与手写都有助于形成和巩固汉字在心理词典中的义音形联结,但手写动作更有利于汉字从正字法代码向书写动作程序的转换;"提笔忘字"现象可能是正字法遗忘的结果,并非由使用拼音输入法造成。     

人际关系适应特征的情境评价方法研究

本研究运用情境评价法对人际关系适应特征进行了实验研究 ,结果表明 :1以 Schutz提出的人际关系六因素为评价标准 ,采用情境评价法比问卷形式能更有效地揭示人际适应特征 ;2在情境评价中 ,以合作为主的情境设置比以竞争为主的情境设置更利于反映出人际适应特征 ;3情境评价采用定向、组织、交流和问题解决等阶段的过程设计符合情境评价的实际进程 ,有助于分阶段展开被试的行为特征 ,提高情境评价的可控性和准确性。
