研究旨在探讨个体分类倾向的发展趋势与影响因素.实验一采用图片、文字两种方式呈现实验材料,并使用不同指导语.要求被试选择三个事物中关系更近的两个.结果表明,成人比儿童具有更显著的按照主题分类的倾向,实验材料的呈现方式对于被试分类倾向没有显著影响.实验二进一步考察了分类倾向的发展轨迹,随着年龄增长,个体按照主题划分事物的倾向增强,由倾向于按照分类学规则向按照主题分类的转变可能发生在小学低中年级之间. 相似文献

研究以139名大学生为被试,采用2(信息素养:高、低)×2(批判性思维倾向:强、弱)×2(信息量:高、低)×2(批判情境:有、无)四因素混合设计,考察个体变量和材料变量对创造性问题提出能力的影响。结果显示:(1)从个体变量看,批判性思维倾向在信息素养预测创造性问题提出能力时起调节作用;(2)从材料变量看,信息量高且含批判情境的材料对创造性问题提出能力有促进作用;(3)个体变量和材料变量在灵活性和独创性上存在交互作用。高信息素养或强批判性思维倾向的被试在含批判情境材料下灵活性、独创性表现更好;低信息素养或弱批判性思维倾向的学生在无批判情境材料下灵活性表现更好,在两种批判情境下独创性无显著差异。 相似文献

童年中晚期攻击的发展轨迹和性别差异:基于母亲报告的分析 总被引:2,自引:0,他引:2
采用母亲报告的方法, 对1618名儿童的攻击进行了4年(9岁~12岁)的追踪研究, 分析了童年中晚期攻击的一般发展轨迹、亚组发展轨迹以及性别差异。结果发现:(1)总体上, 童年中晚期儿童的攻击水平随年龄而下降。(2)基于亚组的准参数模型分析表明, 童年中晚期母亲报告的儿童攻击呈现三条不同的发展轨迹, 即无攻击轨迹、低攻击—下降轨迹以及持续高攻击轨迹, 各轨迹组人数比例分别约为68.7%、26.8%、4.5%。持续高攻击轨迹组以及低攻击—下降轨迹组的儿童在童年晚期均面临一定程度的人际适应困难。(3)多项Logit模型以及卡方检验表明, 男生更倾向于归属于攻击轨迹组(高或者低攻击轨迹组), 而女生更倾向于归属于无攻击轨迹组; 但这并不说明高攻击轨迹组中没有女生, 约2%的女生属于高攻击轨迹组。 相似文献

摘 要 以高低强迫倾向个体为研究对象,考察其在不同概率情景设置的Flanker任务中的信息加工灵活性,研究结果表明:高强迫倾向个体的信息加工方式相对较缓慢、单一,以集中加工方式为主;高强迫倾向个体对情境的变化较少做出反应,在信息加工的灵活性上存在缺陷,而低倾向个体的信息加工方式相对较灵活;高强迫倾向个体不易受线索提示的影响,对信息加工方式的策略性调控能力不足。 相似文献

面对海量网络新闻,直觉或自动化加工过程在信息可信度判断中起重要作用,而与报道人物相关的社会类别信息是重要认知线索。本研究基于社会分类理论,探究网络新闻报道人物的社会分类维度及其与信任知觉的关系。以34名大学生为被试,采取层级分类任务对预备实验中得到的128个人物群体词语进行分类,并用多维标度法进行分析。结果表明,网络新闻人物的社会分类涉及社会地位高/低,社会距离远/近,传统/非传统三个维度,且后两个维度对信任知觉存在显著影响。研究结果揭示了人们对网络新闻报道人物的认知方式,拓展了信任的研究思路和方法。 相似文献

研究以Ellsberg选瓶任务为决策材料,探讨了不同任务特征下个体不确定性容忍度对模糊决策中决策偏好的影响。结果发现,获益情景下:高概率时高、低容忍度个体对模糊选项的选择无显著差异,均偏好模糊规避;中概率时低容忍度个体比高容忍度个体表现出更低程度的模糊规避,前者倾向于模糊中立,后者倾向于模糊规避;低概率时两者对模糊选项的选择无显著差异,均倾向于模糊中立。损失情景下:高概率时两者对模糊选项的选择无显著差异,均倾向于模糊寻求;中概率时低容忍度比高容忍度个体更偏好模糊寻求,前者倾向于模糊寻求,后者倾向于模糊中立;低概率时两者对模糊选项的选择无显著差异,均倾向于模糊规避。这表明,不确定性容忍度对模糊决策偏好产生作用,但这种作用会受到损益概率和损益结果的影响,具有情景依赖性。 相似文献

本研究采用重复囚徒困境实验范式,考察了社会距离和合作指数对不同年龄青少年(初中生、高中生和大学生,且每个年龄段的被试数为40名)在博弈决策中的合作行为的影响。结果发现:(1)随着年龄的增加,青少年合作行为的总体趋势表现为下降;(2)社会距离对大学生的合作行为的正向作用显著,而中学生的合作行为却不受其影响;(3)个体合作率会受到合作指数的促进作用,但这种促进作用在大学生中表现的更为显著。即随年龄增长,个体会更少的采取合作行为,并且个体是否采取合作在更大程度上基于当前博弈中的收支情况和与博弈对象之间的社会距离。 相似文献

为探讨主题关系在儿童归纳推理中的作用,采用经典的三角归纳范式,设计了主题关系和知觉相似冲突、主题关系和分类学关系冲突两种情形,来考察4~5岁儿童在内在属性和情境性属性任务中的归纳推理。结果显示:当主题关系和知觉相似冲突时,从4.5岁开始儿童主要基于主题关系对情境性属性进行归纳推理,而对于内在属性的推论,4~5岁儿童在基于主题关系和基于知觉相似上没有显著差异。当主题关系和分类学关系冲突时,从4.5岁开始儿童主要基于主题关系对情境性属性进行归纳推理,从5岁开始儿童主要基于分类学关系对内在属性进行归纳推理。两个实验结果均发现5岁和5.5岁儿童能够依据不同的属性使用不同的关系推理,表现出归纳灵活性 相似文献

This experiment was aimed at studying both the role of narrow/contextualized categories in the acquisition/organization of conceptual knowledge and the dynamics of categorization decisions. A forced-choice categorization task contrasting thematic and taxonomic responding was used in 4- and 6-year-old children. Before response alternatives were presented, a conceptual organization was pre-activated by means of a matching between the target stimulus and a thematically related, taxonomically related or slot-filler related object. Although taxonomic sorting was prominent overall, it varied as a function of age and of the nature of the pre-activated relation. Responses in accordance with the thematic or taxonomic activations occurred similarly in 4- and 6-year-old children. Age-related effects were however at work in the case of a slot-filler activation: 4-year-old children considered the contextual/contiguity relations between the stimuli but did not weight the equivalence relations (i.e., same occurrence of responses based on the kind of object in the slot-filler and in the thematic activation conditions). More diversified processes appeared to be at work in 6-year-old children. Slot-filler categories were this time considered throughout both their contextual/contiguity structure and their equivalence relations. Results were discussed in terms of availability of conceptual organizations, flexibility abilities, dynamic categorization and preferences. The focus was on implication of slot-filler representations in the construction of conceptual knowledge and in the development of categorization. An important point was to determine whether the age-related changes observed in the slot-filler activation condition could be consistent with Nelson's ( 1983 ) idea that slot-fillers would help passing from a schema-based to a conventional superordinate organization. 相似文献

Knowledge about word and object meanings can be organized taxonomically (fruits, mammals, etc.) on the basis of shared features or thematically (eating breakfast, taking a dog for a walk, etc.) on the basis of participation in events or scenarios. An eye-tracking study showed that both kinds of knowledge are activated during comprehension of a single spoken word, even when the listener is not required to perform any active task. The results further revealed that an individual's relative activation of taxonomic relations compared to thematic relations predicts that individual's tendency to favor taxonomic over thematic relations when asked to choose between them in a similarity judgment task. These results indicate that individuals differ in the relative strengths of their taxonomic and thematic semantic knowledge and suggest that meaning information is organized in 2 parallel, complementary semantic systems.

We investigated the impact of perceptual and categorical relatedness between a target and a distracter object on early referent identification in infants and adults. In an intermodal preferential looking (IPL) task, participants looked at a target object paired with a distracter object that could be perceptually similar or dissimilar and drawn from the same or different global category. The proportion of target looking measures revealed that infants and adults were sensitive to the interplay between category membership and perceptual similarity. Online latency measures demonstrated an advantage for perceptually dissimilar items regardless of their categorical status, indicating that different IPL measures index different processes during target identification. Results suggest that perceptual similarity and category membership of the objects lead to competition effects in word recognition and referent identification in both adults and infants and that lexical categorization and nonlinguistic categorization processes are closely related during infancy. 相似文献

采用认知方式图形测验,对94名普通高中生进行实验研究,探讨了当前普通高中生认知方式特点及其与学绩的关系。结果表明:随着年级的增高,高中生的场独立性增强。高中生的认知方式场依存性、场独立性与学习成绩的相关不显著。在初中毕业刚进入高中,学生的认知方式存在显著的性别差异,但随着年级增长、个体成熟,这种差异逐渐缩小。文理分科对高中生的认知方式发展没有明显的影响。 相似文献

We studied the time course of material categorization in natural images relative to superordinate and basic-level object categorization, using a backward-masking paradigm. We manipulated several low-level features of the images—including luminance, contrast, and color—to assess their potential contributions. The results showed that the speed of material categorization was roughly comparable to the speed of basic-level object categorization, but slower than that of superordinate object categorization. The performance seemed to be crucially mediated by low-level factors, with color leading to a solid increase in performance for material categorization. At longer presentation durations, material categorization was less accurate than both types of object categorization. Taken together, our results show that material categorization can be as fast as basic-level object categorization, but is less accurate. 相似文献
