The relationship between fluid intelligence and sustained inattentional blindness in 7-to-14-year-old children

Previous researches have shown that people with higher fluid intelligence are more likely to detect the unexpected stimuli. The current study systematically explored the relationship between fluid intelligence and sustained inattentional blindness in children. In Experiment 1, we measured one hundred and seventy-nine 7-to-14-year-old children’s fluid intelligence and sustained inattentional blindness. The results showed that fluid intelligence was negatively related to sustained inattentional blindness only in 7-to-8-year-old children. In Experiment 2, we explored sustained inattentional blindness in sixty children with high Raven’s scores. We found that compared with children who have average Raven’s scores aged 11-to-12 years old, children with high Raven’s scores were unable to better avoid sustained inattentional blindness. In general, this research implies that the relation between fluid intelligence and sustained inattentional blindness is weak. Fluid intelligence could predict sustained inattentional blindness only when children do not have enough perceptual capacities to complete the primary task.     

学前儿童朴素情绪理论的发展

对情绪的心理层面的理解是幼儿心理理论发展中出现得相对较迟的能力, 他们如何通过愿望和信念等不同的心理状态对人们的情绪做出判断？随着年龄的增长, 他们采用不同策略推测情绪的能力又发生了什么变化？本研究结合主人公愿望是否得到满足的状态, 通过利用图片故事个别测查的方法探查了90名3~5岁学前儿童在“内容错误信念”任务中对他人情绪的推测。结果显示, 年幼儿童、尤其是3岁幼儿的高兴情绪理解受其对情境是否满足愿望的认知的影响, 呈现出显著的“积极情绪偏差效应”; 学前儿童对情绪的认知表现出从不能采用信念—愿望策略到错误地采用信念—愿望策略、到正确采用信念—愿望策略的发展模式, 且其基于信念的情绪理解在一定程度上呈现出落后于其错误信念理解的“滞后效应”。结果还显示幼儿的惊奇情绪判断不仅由信念成分决定, 也受愿望理解的影响。这些结果突显出心理状态在儿童情绪理解中的重要作用, 揭示出学前儿童相对完整的朴素情绪理论发展模式。     

Do young and old preschoolers exhibit response bias due to different mechanisms? Investigating children's response time

Previous studies have suggested that younger preschoolers exhibit a yes bias due to underdeveloped cognitive abilities, whereas older preschoolers exhibit a response bias due to other factors. To test this hypothesis, we investigated the response latency to yes-no questions pertaining to familiar and unfamiliar objects in 3- to 6-year-olds. The 3-year-olds exhibited a strong yes bias for both objects, and their response latency was significantly shorter than that of the 6-year-olds. The 4- and 5-year-olds did not exhibit any response bias, whereas the 6-year-olds exhibited a nay-saying bias (a response bias to say “no”) for unfamiliar objects. Overall, children’s response bias scores were stronger for familiar objects than for unfamiliar objects. The results suggest that 3-year-olds exhibit a yes bias automatically, but 5- and 6-year-olds are sensitive to question context.     

幼儿对条件许诺的理解

通过给4、5、6岁儿童呈现一系列图片,分别代表孩子、妈妈以及双方违反约定的不同情况,考察了幼儿对条件许诺形式的社会约定的理解。结果表明：幼儿对条件许诺的认知表现出明显的发展趋势,绝大多数幼儿都能指出孩子违反,随年龄增大能指出妈妈违反、双违反的人次百分比逐渐增多,其中4岁组没有人能指出妈妈违反,5岁组没有人能指出双违反;幼儿对条件许诺中不同角色违背的检测存在“角色效应”和“同侪违背优先检测效应”;多数幼儿还没有将条件许诺理解为双条件规则。     

学前儿童心理理论及欺骗发展的关系研究

本文采用两种标准心理理论任务和两种欺骗任务,以3~6岁儿童为被试,探讨了学前儿童心理理论与欺骗发展的关系,得出如下结论:(1)在不同的误信念任务中,学前儿童的表现不一致;但仍存在一般发展趋势:3岁儿童不能通过误信念任务,4、5岁是儿童误信念发展的关键时期.(2)3岁儿童不能拥有隐藏意图的欺骗能力,4岁儿童拥有隐藏意图的欺骗能力.(3)3岁儿童能说谎,但假装无知的欺骗直到6岁才出现.(4)误信念理解与隐藏意图的欺骗存在相关,但与说谎和假装无知不存在相关.     

线索冲突情境下幼儿对不同领域知识的选择性信任特点

探讨幼儿在准确性线索和共识线索冲突情境下对自然与社会领域知识的选择性信任特点。实验1探究幼儿在线索冲突情境下对自然领域知识的选择性信任,选取88名4~6岁幼儿,采用对物品命名的方法,结果发现4岁幼儿依据共识线索进行信任判断,而5~6岁幼儿依据准确性线索进行信任判断;实验2探究幼儿在线索冲突情境下对社会领域知识的选择性信任,选取94名4-6岁幼儿,采用对人格特质命名的方法,结果发现4岁幼儿依据共识线索进行信任判断,5岁幼儿对两类线索没有做出偏向性选择,6岁幼儿依据准确性线索进行信任判断。实验3采用被试内设计,探讨5岁幼儿对两个领域知识的选择性信任,验证了实验1和实验2的相关结果。结论:在线索冲突情境下幼儿对不同领域知识的选择性信任具有不同的年龄发展特点。     

Young children's storage behavior in a memory-for-location task

Two experiments concerned with children's intentional preparation for future retrieval in a memory-for-location task are presented. In the first experiment, 3-, 5-, 7-, and 9-year-olds were instructed to store and subsequently retrieve an object on a large spatial display. All age groups, except the 3-year-olds, tended to store the object at distinctive locations and their retrieval performance was facilitated accordingly. The four age groups did not differ in the types of selections made in a nonmemory control task. The second experiment dealt with the effects of feedback and informational factors on strategy acquisition. Preschoolers were given experience at retrieving the object from distinctive and nondistinctive positions on the stimulus display. Later, when instructed to store the object by themselves, older preschoolers produced the distinctive-position storage strategy following a feedback procedure in which they directly observed the consequences of their retrieval selections. The strategy was adopted by younger preschoolers, but only when additional strategy and task information accompanied visual feedback. The use of external memory tasks with young children and factors affecting strategy acquisition and utilization are discussed.     

Components of phonemic processing and the beginning reader

This study primarily investigated various aspects of phonemic processing and memory in relation to reading in 74 5- and 6-year-old British children. A principal components analysis revealed a major connection between reading and aspects of phonemic processing for both age groups. For the 5-year-olds the processing of the initial phoneme was important for reading, whereas for the 6-year-olds processing of initial and final phonemes appeared to be equally related on this factor. A second factor for both groups was intelligence, which was related to reading only for the 6-year-olds; but this intelligence factor was more associated with phonemic processing for the 5-year-olds. An analysis involving clustering individual readers with similar patterns across the experimental variables showed some consistent profiles for disabled readers across the two age groups. These profiles suggested potential areas for remediation according to subgroup membership.

Exploring mental-state reasoning as a social-cognitive mechanism for social loafing in children

The authors explored mental-state reasoning ability among 72 preschoolers (ages 3-5 years) as a possible developmental mechanism for the well-known social loafing effect: diminished individual effort in a collaborative task. The authors expected that older children would outperform young children on standard mental-state reasoning tests and that they would display greater social loafing than younger children. In addition, we hypothesized that the ability to infer the mental states of others would be predictive of social loafing, but that the ability to reason about one's own knowledge would not. The authors gave children three standard false-belief tasks and participated in a within-subjects balloon inflation task that they performed both individually and as part of a group. Results indicated that 3-year-olds performed significantly below older preschoolers on mental-state reasoning tasks. Only 4- and 5-year-olds displayed diminished individual effort. Multiple regression analysis indicated that only the ability to reason about others' false beliefs accounted for a significant amount of variance in social loafing; age (in months) and own false-belief reasoning did not. The authors discussed theoretical and pedagogical implications.     

The effects of age and cue-action reminders on event-based prospective memory performance in preschoolers

The present study investigated event-based prospective memory in five age groups of preschoolers (i.e., 2-, 3-, 4-, 5-, and 6-year-olds). Applying a laboratory-controlled prospective memory procedure, the data showed that event-based prospective memory performance improves across the preschool years, at least between 3 and 6 years of age. However, our findings do not confirm early speculations that 2-year-olds may have attained reliable skills to carry out future intentions on their own. By contrast, there were first signs of prospective memory abilities among the 3-year-olds. The present study also revealed that children as young as 3 years can use external memory aids in the form of cue-action reminders to improve their event-based prospective remembering. Finally, the findings suggest that parents or caregivers can adequately estimate their preschool children's prospective memory abilities, as revealed by applying a modified version of the Prospective and Retrospective Memory Questionnaire (PRMQ).     

规则顺序与规则类型对儿童规则推理的影响

学前儿童时期是各种推理能力产生和发展的重要时期。本研究采用Frye和Zelazo等（1996）所设计的“二进二出”装置,设置了规则顺序、规则类型的规则推理任务,采用个别实验法,研究了90名3～4岁儿童规则推理能力的发展。在本研究条件下,结果发现：1．当规则呈现顺序不同时,儿童规则推理成绩差异显著,先呈现哪个规则,则利用这个规则进行推理的成绩就较好;2．不同规则类型下儿童的推理成绩差异极其显著,竖直规则下的推理任务更容易;3．3．5～4岁是儿童二维合取规则推理能力发展的快速期。     

竞争和合作对学龄前儿童分配模式的影响:心理理论和抑制控制的作用

研究考察在双方贡献不相等时,3~6岁儿童分配模式的发展趋势及其原因。98名儿童在竞争或合作情境下和玩偶进行钓鱼游戏,然后对6枚冰箱贴进行分配。结果发现5~6岁儿童比3~4岁儿童进行平均分配的比例更高,一级心理理论和抑制控制能力完全中介了年龄的效应。和竞争情境相比,合作情境促进儿童进行平均分配,同时情境调节了抑制控制对分配模式的影响。研究表明一级心理理论和抑制控制能力的发展能够解释学龄前儿童分配模式的变化。     

Developing domain-specific causal-explanatory frameworks: the role of insides and immanence

Two studies investigate children's knowledge of internal parts and their endorsement of immanent causes for the behaviors of living and non-living things. Study 1, involving 48 preschoolers, showed that domain-specific knowledge of internal parts develops between ages 3 and 4. Study 2 included 43 4-year-olds, 30 8-year-olds, and 35 adults and showed that preschoolers do not endorse these internal parts as causally responsible for familiar biological events (e.g., movement, growth). Like adults and older children, however, preschoolers endorse an abstract cause, “its own energy,” for animals but not for machines. The results suggest that children recognize domain-specific internal parts as early as age 4 but that their causal attributions are not yet anchored in a detailed biological theory. Findings are discussed in terms of theory change and an essentialist assumption.     

Children's response biases to results of object sharing

This study investigated whether 2- to 6-year-old children exhibit a response bias to questions pertaining to the results of sharing objects that should attract their interest. An experimenter distributed four objects between herself/himself and a child, equally or unequally (more to the child or more to the experimenter) and asked the child yes-no questions: “Is this okay?” and “Is this bad?” The results indicated that 2- and 3-year-olds exhibited a yes bias in all conditions, 4-year-olds exhibited a yes bias to the equal condition and to the unequal condition with more distributed to the child, and 5-year-olds exhibited a yes bias to both unequal conditions, whereas 6-year-olds did not show any response bias. Young preschoolers exhibited a yes bias regardless of questions and children may become able to say both “yes” and “no” appropriately to questions about object sharing after the age of six.     

2~5岁学前儿童数概念的发展水平及过程——理解者水平理论的视角

本研究从儿童数概念发展的理解者水平模型的理论视角,对100名2～5岁学前儿童的数概念发展水平进行划分,并比较不同水平儿童对后继函数的理解和掌握,探讨儿童数概念的发展过程。结果表明：儿童在4岁时基本达到了数概念发展的最高水平即基数原则水平,已经理解了后继函数,能够把它的方向性和单位性的变化,对应到数数序列的数词上。而2～3岁的儿童还处于子集水平,该水平的儿童和基数原则水平的儿童相比,对后继函数的理解存在差异。但后继函数的发展不是全或者无的,儿童积累的数词越多,后继函数发展得越好。     

Truck Driver or Nurse? The Impact of Gender Roles and Occupational Status on Children’s Occupational Preferences

Three experiments examined how US children perceive occupational status and gender roles. In Experiment 1, 107 6-to-12-year-olds rated the status and gender roles of 54 occupations. Feminine occupations were underrepresented among the perceived high status jobs. In Experiment 2, 28 6-to-8-year-olds, and in Experiment 3, 36 9-to-12-year-olds, reported their preferences for equally high status masculine and feminine occupations and low status masculine and feminine occupations. In both experiments, girls preferred feminine to masculine occupations and status only affected preferences for masculine occupations. The younger boys’ preferences were based on both variables, whereas older boys’ preferences were based on status. These findings imply that occupational status may influence boys’ vocational preferences more than pressure to conform to masculine gender roles.     

Toddler peer interaction in mixed-age groups

Toddler preference for different age playmates was investigated. Thirty toddlers, aged 16 to 23 months, were observed in family day care homes. Each subject had access to both same-age and older peers. Results indicate that toddlers preferred 2-year-olds compared to same-age peers. Toddlers watched preschoolers more often than same-age peers. Toddlers also used more imitation and language in their play with 2-year-olds compared to other age peers. Features of the caregiving environment were also assessed. Higher levels of arousal and motion were associated with more elaborate peer interaction. These findings support the notion that partner age and the caregiving environment can influence toddler social interaction.     

4～7岁儿童对人的目的指向行为的归因研究

该研究根据人的三种基本生物需要(吃、喝、睡)设计动画故事脚本,通过计算机呈现的方式,探查4~7岁儿童对人的生物需要目的指向行为的归因。结果表明:(1)学前儿童能够对人的生物需要目的指向行为进行非意图的生物学解释,4岁至5岁是一个快速发展期;(2)学前儿童对人的生物需要行为的理解表现出不一致性,其“睡”和“吃”受社会因素影响较大,“喝水”表现为一种纯粹的生物需要(3)学前儿童对人的生物需要行为的满足与否能够采取灵活的多因果解释模式。     

Sociolinguistic contexts of the preschool

Two studies were conducted to determined the effects of specific learning centers on preschoolers' functional uses of language. In Study 1, preschoolers in three separate same-age classrooms (2-, 3-, and 5-year-olds) were observed on a time sampling scheduling during their free play periods for four weeks. Preschoolers' individual utterances were coded as serving one or more than one function; functions were defined following Halliday. The housekeeping and block centers tended to elicit the most individual and multifunctional utterances. The fantasy play and social interaction among children in these centers were thought to be responsible for this mature use of language.In Study 2, same-age and same-sex dyads from two age groups (4- and 5-year-olds) were observed in experimental settings playing with blocks alone and with dramatic props alone. Both contexts elicited a predominance of imaginative language, though the dramatic context elicited more imaginative language than the blocks. With age, children generated more individual functions and multifunctional utterances.
