压力与画对儿童错误记忆影响的实验研究

该研究主要探讨了有无压力和画与不画对儿童虚构生活事件记忆的影响。压力用该类研究中常用的医疗模式来进行诱导,结果表明可以使儿童易受暗示性提高,降低“是”反应的标准,增加对虚构生活事件的肯定反应,但可能存在年龄的差异;而画的方式,可能会使儿童混淆所画与所经历事件,儿童通过画使更多的线索被引导出来,导致把虚构的生活事件作为发生过而给予肯定的反应。     

儿童外显视空间注意转移

采用提示范式探讨了三、六年级儿童的外显视空间注意转移。实验结果表明：内源性提示下儿童表现出显著的提示效度效应,其效度效应量在年龄组间没有显著差异;较短SOAs的外源性提示下,儿童表现出显著的提示效度效应;较长SOAs的外源性提示下儿童没有表现出返回抑制效应。用注意的过滤器理论和对象文件模型讨论了本研究的结果     

儿童青少年大脑认知功能事件相关电位P_（300）的年龄特征

从发展心理学的角度．对幼儿到大学六个年龄组的儿童青少年进行了事件相关电位Ｐ_（３００）测定．结果发现：反映大脑认知功能的事件相关电位Ｐ_（３００）各成分随着年龄增长而发展的趋势十分明显,从而进一步说明了认知发展的特点与大脑高级神经系统活动功能发展特点的密切关系。     

3～5岁儿童概念比较过程研究

本研究以两个实验探讨了儿童的一个认知过程:人优先考虑共同性,其次才是组合差异性与非组合差异性。3~5岁三个年龄组儿童分别对日常生活的基本概念进行类似性判断与差异性判断。实验1的结果表明,3岁年龄组的儿童还没有表现出组合差异性,4岁年龄组的儿童初步表现出明显的组合差异性,5岁年龄组的儿童表现出明显的组合差异性。他们首先考虑共同性,其次才是组合差异性与非组合差异性。实验2的结果表明,5岁儿童比4岁儿童更多地表现了组合差异性的判断能力。最后以结构组合的观点讨论了这些结果。     

特质标签对儿童错误信念理解的影响

该研究将错误信念任务中主人公加上"聪明"或"笨"的标签,以考察特质标签是否会影响儿童对错误信念的理解。360名5~8岁儿童参加实验,每个年龄组儿童随机分配到"聪明"标签组、无标签组和"笨"标签组。结果表明:(1)"聪明"标签会极大地阻碍67、岁儿童理解他人错误信念,对5、8岁儿童没有影响;(2)"笨"标签对所有年龄组儿童错误信念的理解都没有产生影响。     

从博弈游戏看儿童经济决策行为的发展

国外有研究借助最后通谍（UG）和独裁者博弈（DG）探查了儿童的决策行为,他们发现,随着儿童年龄的增长,他们分配给对方的金额呈上升趋势,即公平和分享行为随年龄增加。儿童的经济决策行为和社会化不可避免要受文化影响。研究探查了中国文化下小学三、六年级、初二、大学一年级四个年龄组学生在最后通谍（UG）和独裁者博弈（DG）中的经济决策行为发展。研究同时比较了个体决策和群体决策的差异。结果发现：儿童在两个博弈中的提议金额都显示出公平和分享行为,随着儿童年龄的增长,儿童在UG和随后进行的DG中的提议分配金额呈减少趋势。这个发现与以往国外研究结果明显不同。两个博弈的顺序对UG没有影响,但对DG有影响;儿童的个体决策和群体决策结果没有显示显著差异     

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。     

规则的不同特点对儿童判断的影响

本研究探讨不同领域的规则(安全领域规则,个人领域规则)和不同的规则提出者(成人权威,同辈权威)对儿童判断的影响。研究考察了48名4~7岁的儿童在道义推理、奖惩判断、愿望理解和行为判断的发展变化特点。结果表明:(1)直到7岁儿童才能根据规则的不同特点做出不同的判断,7岁儿童预测更不应该违反安全领域规则,违反安全领域规则和成人权威制定的规则后应该受到更多的批评,而4岁组和5岁组儿童在不同规则情境下的判断没有显著差异;(2)各年龄组儿童预测应该给予表扬的数量在各情境下没有显著差异;(3)在规则与愿望相冲突时,高年龄组儿童比低年龄组儿童更多地报告主人公会坚持自己的愿望;(4)在预测主人公是否会违反规则上,各年龄组在不同规则情境下均无显著差异。     

韦氏儿童智力量表中美两种版本的因素分析:两国样本的年龄组间比较

本研究使用LISREL 方法分别对韦氏儿童智力量表美国修订本(WISC-R)与中国修订本(WISC-CR)的六岁半至十六岁半儿童样本做了因素分析,从而发现了适于中美儿童的最佳共同的因子模型。这一模型包括三个因子:言语理解、知觉组织和不分心能力。同时,使用LISREL 多样本分析就相同文化的不同年龄组间,不同文化的各年龄组间进行因素模式一致性的比较。中美样本的分析结果都表明,年幼的与最大的年龄组适合共同的因子模型好于其他年龄组。适合共同模型最好的年龄组也表现出较高的跨文化因素模式的一致性。分析表明,教育与经验是形成能力差异与模型吻合差异的重要来源之一。     

语音与词义激活的相对时间进程:来自儿童发展的证据

本研究从儿童语言发展的角度．在已有研究基础上．进一步考察了汉语视觉字词加工中语音与词义激活的相对时间进程。运用启动命名技术,比较了三年级和六年级儿童在语音和语义启动中的表现。结果发现,三年级和六年级儿童都有语音和语义启动效应,且六年级儿童更为显著。但语义启动和同音启动的促进效应之间没有差异,而同音不同声调启动则可能产生抑制作用。文章探讨了这些发现对汉语视觉字词加工中词义信息提取不同观点的含义。     

Drawing conclusions: The effect of instructions on children's confabulation and fantasy errors

Drawing is commonly used in forensic and clinical interviews with children. In these interviews, children are often allowed to draw without specific instructions about the purpose of the drawing materials. Here, we examined whether this practice influenced the accuracy of children's reports. Seventy-four 5- and 6-year-old children were interviewed one to two days after they took part in an interactive event. Some children were given drawing materials to use during the interview. Of these children, some were instructed to draw about the event, and some were given no additional instructions at all. Children who were instructed to draw about the event, or who were interviewed without drawing, made few errors. In contrast, children who drew without being given specific instructions reported more errors that were associated with both confabulation and fantasy. We conclude that, to maximise accuracy during interviews involving drawing, children should be directed to draw specifically about the interview topic.     

The development of the memorability-based strategy: insight from a training study

We investigated whether the memorability-based strategy, a process supporting the rejection of nonexperienced event occurrence, could be promoted through training. The performance of children who received memorability-based training was compared with that of (a) children who received source-monitoring training and (b) children who did not receive any specific training but were instructed to be as accurate as possible. Participants (142 6- to 10-year-olds) enacted common and bizarre actions. Eighteen days later, participants received misinformation about the first session. Five days after being misinformed, children were questioned about the first session. Compared with children in the no training condition, those in both training conditions reported significantly more true events, but only older children who received the memorability-based training were more likely to reject bizarre suggested events. Age interacted with action type when metacognitive assessments about false event rejection were examined, consistent with the idea that the use of the memorability-based strategy develops late during the elementary school years.     

Human figure drawings of gender-problem children: A comparison to sibling,psychiatric, and normal controls

The Draw-a-Person test was used to evaluate a number of questions regarding children referred for potential problems in their gender-identity development (N = 36). Sibling (N = 31), psychiatric (N = 23), and normal (N = 30) children served as comparison groups. The major results included the following: (1) The gender-referred children were more likely to draw an opposite-sex person when requested to "draw a person" than were the other three groups; (2) the gender-referred children who drew an opposite-sex person were more likely to play with opposite-sex toys and dress-up apparel on a free-play task than were the gender-referred children who drew a same-sex person; (3) the gender-referred children drew taller opposite-sex persons than same-sex persons; (4) using Koppitz's (1968) criteria, the normal children had a smaller proportion of emotional disturbance indicators in their same-sex drawings than did the other three groups. These findings were discussed with regard to psychometric and interpretive issues in the assessment of children with atypical gender-role behavior.     

The Clinical and Forensic Value of Information that Children Report While Drawing

Drawing is commonly used in clinical interviews to help children talk about their experiences. Research has shown that drawing increases the amount of information that children report about some emotional experiences. Here, we aimed to investigate the use of drawing in interviews about other, clinically relevant emotions, and the clinical and forensic relevance of the information that children report while drawing. To do this, sixty 5‐ to 6‐ and 11‐ to 12‐year‐olds drew and told, or told, about prior experiences that had made them feel happy, angry, proud (confident), and worried (nervous). For all emotions, drawing and telling increased the amount of forensically relevant, episodic details (e.g., who was there and what happened) that children reported relative to telling alone. In contrast, drawing and telling did not alter the amount of information that children reported about clinically relevant details (e.g., thoughts and emotions). We discuss the implications of these findings for using drawing in interviews with children. Copyright © 2013 John Wiley & Sons, Ltd.     

da Vinci's window facilitates drawings of total and partial occlusion in young children

When two or more objects are present in a scene, children 5 and 6 years of age rarely draw the scene such that one object totally or partially occludes another object. Instead they draw complete objects. The present study separated two components of drawing: perspective taking and graphic skill. Perspective taking was examined by comparing a free viewing condition with a restricted viewing condition in which a model could only be viewed through four apertures. Graphic skill was examined by comparing drawings requiring total occlusion with drawings requiring partial occlusion under both viewing conditions. Experiment 1 showed that 90% of 5- and 6-year-olds drew total occlusions under restricted viewing conditions but only 32% did so in the free viewing condition. Experiment 2 showed that drawings of partial occlusion were unaffected by viewing condition among 5-year-olds, but that restricted viewing increased the number of partial occlusions that 6-year-olds drew. Thus, failures of young children to draw occlusions have less to do with graphic skill than was previously thought. Instead, it is suggested that young children have a more general difficulty selecting one perspective and maintaining it over time.     

Does drawing facilitate older children's reports of emotionally laden events?

Although it is well‐established that drawing about an event increases the amount of verbal information that young children provide during an interview, it is unclear whether drawing continues to facilitate children's reports as they get older. In the present experiment, 90 children, ranging from 5‐ to 12‐years old, were asked to draw and tell or to just tell about emotional events they had experienced. Children of all ages reported more information when asked to draw and tell rather than to tell only. Drawing had no negative effect on the accuracy of children's accounts. Drawing also increased the number of open‐ended questions and minimal responses that interviewers used. We conclude that drawing may be a useful tool in clinical and forensic settings with children of all ages; it increases the amount of information that children report and the number of appropriate questions that interviewers ask.

The role of nonlinguistic stimuli and semantic relations in children's acquisition of grammatical utterances

Eighteen children, randomly assigned to one of six conditions, were trained in the use of two-word subject-verb (e.g. “mommy go”) utterances. The groups differed in (1) the number of different semantic relations theoretically underlying the subject-verb utterances on which the children were trained, and (2) the extent to which these semantic relations were associated with nonlinguistic events. The results indicated that the children acquired the subject-verb utterance forms more readily when they were also exposed to the events to which the utterances actually referred. Provided that the subject-verb utterances were related to ongoing events, the number of relations “underlying” these utterances did not appear critical. These results suggest that the child's acquisition of novel and grammatical utterances describing nonlinguistic stimuli highly similar to those in his natural environment are amenable to experimental control.     

‘No fair, copycat!’: what children’s response to plagiarism tells us about their understanding of ideas

Adults believe that plagiarizing ideas is wrong, which requires an understanding that others can have ideas and that it is wrong to copy them. In order to test when this understanding emerges, we investigated when children begin to think plagiarism is wrong. In Study 1, children aged 7, 9 and 11 years old, as well as adults, disliked someone who plagiarized compared to someone who drew an original drawing or someone who drew an identical picture by chance. Study 2 investigated the same question with younger children, focusing on children aged 3–6 years old. Children aged 5–6 years old evaluated plagiarizers negatively relative to unique drawers, but 3–4-year-olds did not. Study 3 replicated the findings from Study 2 and found that children justify their negative evaluations of plagiarizers by mentioning concerns over copying. These experiments provide evidence that, by age 5 years old, children understand that others have ideas and dislike the copying of these ideas.     

Does Children's Colour Use Reflect the Emotional Content of their Drawings?

When children draw in clinical contexts, clinicians sometimes rely on children's colour use to make inferences about their emotional reaction to the subject of the drawing. Here, we examined whether children use colour to portray emotion in their drawings. In Experiment 1, children indicated their colour preferences and then coloured in outlines of figures characterized as nasty or nice. Children also drew complex, multi‐coloured pictures about their own happy or sad experiences. In Experiment 2, hospitalized children drew about being worried or scared in hospital and about their positive experiences. In both experiments, we examined the relation between children's colour use and their colour preferences. Three‐ to 10‐year‐old children used more preferred colours to colour in the nice outline. Although they were more likely to use non‐preferred colours to colour in the nasty outline, they tended to used a mix of preferred and non‐preferred colours. When both normal and hospitalized children produced drawings about positive and negative events, there was no relation between children's colour choices and their colour preferences; children primarily used preferred colours. These data suggest that clinicians should exercise extreme caution when interpreting the meaning of colour in children's drawings. Copyright © 2011 John Wiley & Sons, Ltd.
