观点采择因素对3～4岁儿童延迟满足决策的影响

通过采用延迟满足决策任务,要求儿童分别为自己和他人做出决策,本研究考察了观点采择因素对儿童情感决策发展的影响。实验一选取3岁和4岁儿童各40名,结果发现3岁儿童和4岁儿童在为自己选和为他人选两种条件下的表现均无显著差异,都倾向于做出延迟选择。实验二选取3岁和4岁儿童各60名,在为他人的选择中进一步区分了不同的观点提示条件,并增加了观点采择测验任务。结果发现,4岁儿童的观点采择能力得到了初步的发展,在不同的观点提示条件下为他人选择时分别表现出了与为自己选择不同的决策趋势;3岁儿童尚未获得观点采择能力,在各种不同观点提示条件下为自己和为他人做选择时差异均不显著。本研究结果表明,观点采择能力对儿童情感决策的影响是发展性的。随着观点采择能力的发展,儿童逐渐能够确立正确的延迟动机,为他人做出有效的决策。     

儿童社会观点采择的发展及其子类型间的差异的研究

对幼儿园大班至小学阶段的４２５名儿童施以认知和情感两类观点采择测验,考察儿童社会观点采择发展的一般趋势以及两类观点采择的发展趋势及水平上的差异。结果发现：６岁左右儿童在准确推断他人观点方面还存在较大困难。６—１０岁左右是儿童社会观点采择能力快速发展的时期。１０岁左右儿童已能根据环境信息较准确推断他人的观点：儿童认知观点采择与情感观点采择能力的发展趋势基本一致,但后者的发展水平极显著地落后于前者。     

儿童在认知物体时区分看见的和知道的观点采择能力发展的实验研究

本研究旨在探讨儿童认知物体过程中是如何发展区分自己的心理意象与他人现实环境中获得的视觉信息的能力,即区分看见的和知道的观点采择能力。结果发现:(1)5岁儿童才基本具备观点采择能力。(2)不同年龄的儿童具有不同的观点采择水平模型和年龄特征。(3)在不同的信息种类条件下儿童上述的观点采择能力的发展是不同步的。(4)呈现不同的视觉信息也影响儿童上述的观点采择。(5)儿童在观点采择过程中产生错误主要是由于儿童不能把自身对客体的不确定信息的区分外推到他人身上去而造成的。     

4～6岁幼儿经济博弈中的信任行为及其影响因素

本研究通过两个实验考察幼儿是否在博弈任务中表现出对陌生人的信任行为,同时考察可能对幼儿的信任产生影响的因素,包括个体认知因素(观点采择)和环境因素(负性反馈和代际传递)。研究对189名4~6岁幼儿及其家长进行多种任务的测量。实验一通过修订Evans和Krugger(2011)的信任博弈任务,考察幼儿在匿名信任博弈中的信任行为,结果发现与4岁幼儿相比,6岁幼儿对他人的信任更低;实验二考察了幼儿信任的影响因素,结果发现,幼儿在得到负性反馈结果后再次进行信任博弈任务时,他们对他人的信任比前次有所降低,6岁幼儿对他人返还数量的预期比4岁幼儿下降程度更大;6岁幼儿的信任行为(第一次给出意愿)与观点采择能力显著相关;6岁幼儿的信任水平与家长的信任水平显著相关。     

3岁幼儿的二级观点采择及合作互动的影响

研究以经典的乌龟任务(实验1)和改良的滤镜任务(实验2)对3岁幼儿的二级观点采择进行探究, 并探讨其在短暂的社会互动前后的变化。结果表明：(1) 3岁幼儿尚难以自发进行二级观点采择, 但已具备进行这一加工的潜质; (2)短暂的合作互动可在一定程度上提高幼儿采择他人观点的成功率, 而竞争互动则无类似影响。该发现为从建构主义角度解释视觉观点采择发展提供了新的证据。     

幼儿心理理论愿望信念理解与情绪理解关系研究

考察了幼儿心理理论信念愿望理解与情绪理解的发展状况及相互关系.运用实验法对256名3~6岁儿童施测.结果表明:(1)幼儿心理理论愿望-信念理解与情绪理解的发展在3~6岁期间随年龄逐渐提高.4岁是基于信念的情绪理解能力发展的关键年龄;4~5岁是幼儿情绪观点采择能力发展的关键年龄.(2)幼儿基于信念的情绪理解能力的发展晚于错误信念理解能力的发展.(3)幼儿心理理论的愿望-信念理解与情绪理解之间相关显著.     

学前儿童对事实、信念、愿望和情绪间关系的认知

76名3至5岁儿童接受了区分事实和信念、根据信念推测他人愿望、根据愿望推测他人情绪等实验任务,通过考查学前儿童对事实、信念、愿望和情绪间关系的认知,探察学前儿童心理理论发展的特点。结果显示3岁儿童在区分信念和事实时,出现错报事实或错报信念两种错误,而不单纯是现实主义偏向错误;在推测他人愿望时,部分3岁和4岁儿童虽然能够正确报告他人的信念却不能正确推测他人愿望,愿望认知发展有其复杂性的一面。学前儿童主要依据愿望推测他人情绪,儿童对信念和愿望的认知水平制约儿童对他人情绪的理解。     

语言加工过程中的观点采择及其认知机制

观点采择是指个体从他人或他人所处情境出发, 想象或推测他人观点与态度的心理过程。对相关研究综述发现: (1)观点采择是否存在自我中心偏向依然存在争论; (2)观点采择自我中心偏向不是始终存在的, 其原因可能是个体受到时间压力和特定类型任务的要求; (3)他人存在影响观点采择自我中心偏向, 并且这种影响是自动化的, 不受任务类型的影响; (4)观点采择的认知机制主要包括交互对齐、记忆提取和概率计算。未来研究需要: (1)整合已实现的计算模型; (2)进一步探究观点采择能力与心理理论的关系; (3)探究观点采择中私有信息的作用; (4)提高观点采择研究的生态效度; (5)采用不同的技术手段进行汇聚性验证。     

3～5岁儿童情绪能力的年龄特征、发展趋势和性别差异的研究

本研究采用测验法和问卷法,考察了150名3～5岁儿童的情绪能力的年龄特征、发展趋势和性别差异。结果表明:(1)3～4岁幼儿的情绪理解能力有显著变化,对积极情绪的理解要高于对消极情绪的理解,女孩推测他人情绪状态的能力高于同龄男孩;(2)幼儿能够运用多种策略来应对同伴之间的冲突情境,使用频率最高的策略是建构性策略,其次是回避和情绪释放策略,最后是破坏性策略;(3)幼儿的情绪观点采择能力能够预测情绪调节的发展。     

奖惩频率对3～5岁幼儿完成博弈任务的影响

通过对情感决策的常用研究工具——标准爱荷华博弈任务进行了得失总量不变而频率改变的修改,并使之适合于年幼的3～5岁儿童,可以比较幼儿在不同奖惩频率任务中的表现,从而考察奖惩频率对幼儿情感决策的影响。对120名3～5岁幼儿在四种不同类型的任务中的表现进行分析后,所得实验结果如下:(1)儿童对惩罚和奖励频率的变化比较敏感:正向博弈任务中,"有利纸牌不变,不利纸牌的惩罚总量不变,只增加不利纸牌的惩罚频率"可以使3～5岁儿童完成博弈任务的成绩有显著提高;逆向博弈任务中,"不利纸牌不变,有利纸牌的奖惩总量不变,而有利纸牌奖励频率的增加"能促使4～5岁幼儿更多更快地做出正确选择。(2)幼儿的情感决策能力在3～4岁时期发展迅速,而在4～5岁时仍然有较快发展。     

情绪、职业数量对不同职业生涯延迟满足大学生职业决策过程的影响

为探究情绪与职业数量对不同职业生涯延迟满足个体职业决策过程的可能潜在影响,分别对40名高、低职业生涯延迟满足倾向的大学生被试诱发正、负性情绪并完成信息板技术模拟的职业决策任务。结果显示:1)高延迟满足个体的搜索深度和搜索模式显著大于低延迟满足个体;2)不同延迟满足的个体在正性情绪或低职业数量条件下都表现出更好的搜索深度和搜索模式;3)在不同情绪及职业数量条件下,高延迟满足个体在不同职业属性间的搜索更多。职业生涯延迟满足倾向作为与未来规划密切联系的概念,揭示了个体职业生涯规划对其职业决策过程可能存在的影响。     

Development of affective decision making for self and other: evidence for the integration of first- and third-person perspectives

The role of perspective taking in affective decision making was studied in children at two ages (3 and 4 years) using a delay-of-gratification paradigm in which children chose between an immediate reward of lower value and a delayed reward of higher value. Half the children chose for themselves (self condition), and half chose for the experimenter (other condition). Three-year-olds chose delayed rewards in the other condition but made impulsive choices in the self condition. Compared with 3-year-olds, 4-year-olds performed better in the self condition and worse in the other condition. Results suggest that 3-year-olds took either a subjective, first-person perspective (for self) or an objective, third-person perspective (for other). Four-year-olds integrated these perspectives, considering a third-person perspective in the self condition and the experimenter's subjective perspective in the other condition (i.e., her desire for immediate gratification). This integration allowed reason to be tempered by emotion, and vice versa.     

The ability of children to delay gratification in an exchange task

The ability to wait for a reward is a necessary capacity for economic transactions. This study is an age-related investigation of children's ability to delay gratification in an exchange task requiring them to wait for a significant reward. We gave 252 children aged 2-4 a small piece of cookie, then offered them an opportunity to wait for a predetermined delay period before exchanging it for a larger one. In a first experiment, the children had to exchange the initial food item for rewards two, four or eight times larger. Results showed that children aged 3-4 years old sustained longer time lags for larger rewards than for smaller rewards. This effect was not found in 2-year-old subjects. In a second experiment, a reward 40 times larger than the initial piece was offered to determine the maximum waiting time that children could sustain. All age groups increased their performances. Older children were more successful at waiting, but some children as young as 2 years old were able to tolerate delays of up to 16 min. Older children who chose to give up waiting earlier than their known capacity demonstrated anticipation skills which had not been seen in younger children, showing that they had anticipated an increase in the time lag, and that they had considered both time and reward value when making their decision. Despite the age effect, we did not establish any limits for delaying gratification in children. This study may have educational implications for dealing with behavioral misconduct, which is known to be related to impulsivity control in young children.     

四种注意情境下幼儿自我延迟满足的实验研究

将120名中等自控能力的3～5岁幼儿随机分配到四种注意情境下:两种奖励物同时呈现、只呈现即时奖励物、只呈现延迟奖励物、两种奖励物都不呈现,以探索幼儿自我延迟满足的注意机制及发展特点。结果发现:(1)幼儿自我延迟满足在两种奖励物都不呈现情境下平均延迟时间最长,在呈现奖励物的三种情境下平均延迟时间较短,表现出跨年龄稳定性;(2)3～5岁幼儿自我延迟满足发展存在显著年龄差异,表现出随年龄增长而提高的趋势。     

3~5岁幼儿自我延迟满足的发展特点及其中澳跨文化比较

采用实验室实验和情境观察相结合的方法,考察了我国3~5岁幼儿自我延迟满足发展的特点及中澳幼儿自我延迟满足的跨文化差异。研究结果表明：(1) 3~5岁幼儿自我延迟满足平均延迟时间随年龄增长而延长;3岁幼儿使用延迟策略少,4岁幼儿主要使用寻求策略,5岁幼儿主要使用寻求策略和自我分心、问题解决策略,自我言语控制策略在整个幼儿期始终不具有显著优势性。(2) 澳大利亚幼儿自我延迟满足发展水平高于我国同龄幼儿;在延迟策略选择上中澳幼儿既具有差异性,又具有一定的相似性;文化价值观通过教育影响着幼儿自我延迟满足的发展。     

Developmental and sex-related differences in preschoolers' affective decision making

This study investigated developmental and sex-related differences in affective decision making, using a two-deck version of Children's Gambling Task administered to 3- and 4-year-old children. The main findings were that 4-year-old children displayed better decision-making performance than 3-year-olds. This effect was independent of developmental changes in inductive reasoning, language, and working memory. There were also sex differences in decision-making performance, which were apparent only in 3-year-old children and favored girls. Moreover, age predicted awareness of task and the correlation between the latter and decision-making performance was significant, but only in 4-year-old children. This study thus indicates that there is a remarkable developmental leap in affective decision making, whose effects are apparent around the age of 4, which according to our results, also marks the age when the correlation of declarative knowledge and decision-making performance becomes significant.     

孤独症个体的公平决策：心理理论和自我/他人情绪识别的作用

研究通过最后通牒任务,考查孤独症儿童在公平任务中的决策,以及心理理论和识别自我/他人情绪对决策的影响。29名孤独症儿童和三组对照组儿童参加实验结果发现,孤独症儿童在任务中面对不同分配比例的接受率（2:8、3:7）与对照组之间存在显著差异。心理理论能力和自我情绪识别都与决策存在相关：当处于不公平的情况下（1:9、2:8、3:7）,通过心理理论任务的孤独症儿童才会拒绝接受不公平分配,儿童也会感觉到不高兴并且做出拒绝的决定。     

Conflicting desire and the child's theory of mind

We contrast the standard representational theory-of-mind approach to the understanding of mental states with an alternative view that theory-of-mind tasks require executive functioning or the inhibition of more “cognitively salient” information. Two experiments test the hypothesis that 3-year-olds' apparent problems on theory-of-mind tasks are not due to an inability to represent the mental contents of another, but rather lie in the informational structure of the task. In Experiment 1, 3- to 5-year-olds were tested on their understanding of desire in others either when they themselves held a strong and conflicting desire or when they had no strong desire. Results showed that under the condition of having a strong and conflicting desire, only 5-year-olds were able to recognize that another person may desire something different. In contrast, when the children themselves held no strong desire, even 3-year-olds were able to judge another's desire correctly. Experiment 2 compared 3-year-olds' performance on a standard false-belief task with an equivalently structured desire task in which participants had again to inhibit their own strong and conflicting desire. Results showed similar performance on the traditional false-belief task and the new conflicting-desire task.     

Parental Contributions to the Delay of Gratification in Preschool-aged Children

Delay of gratification in young children has been linked to long-term behavioral and academic outcomes. This study explored parent behavior during a laboratory paradigm as possible associates of delay ability. The sample consisted of 50 two- and three-year-old children and their primary caregivers. A newly created laboratory task, the gift delay task, was conducted to assess delay of gratification. Additionally, parents completed a child temperament (EASI-III) questionnaire. Based on the award-oriented behavior in the gift delay task, children were classified into three groups: delay (20 %), touch and go (i.e., approached the gift, but demonstrated some delay ability; 46 %), and non delay (34 %). Likewise, parents were classified into three groups: non-directive (parents did not initiate any interactions, but may have participated in child-led activity), active (parents initiated interaction with the child no more than 3 times), and very active (parents initiated 4 or more interactions with the child). Significant differences in emotionality and impulsivity were found between the 3 groups of children; additionally, significant differences in delay ability were found based on parent classifications suggesting that there is an optimal level of involvement on part of the parent that helps the child to wait, but beyond this point, involvement may be detrimental to a successful delay outcome. Implications for behavioral interventions focused on parental support and scaffolding are discussed.
