Infants' intermodal perception of two levels of temporal structure uniting the visual and acoustic stimulation from natural, complex events was investigated in four experiments. Films depicting a single object (single, large marble) and a compound object (group of smaller marbles) colliding against a surface in an erratic pattern were presented to infants between 3 and
months of age using an intermodal preference and search method. These stimulus events portrayed two levels of invariant temporal structure: (a) temporal synchrony united the sights and sounds of object impact, and (b) temporal microstructure, the internal temporal structure of each impact sound and motion, specified the composition of the object (single vs. compound). Experiment 1 demonstrated that by 6 months infants detected a relation between the audible and visible stimulation from these events when both levels of invariant temporal structure guided their intermodal exploration. Experiment 2 revealed that by 6 months infants detected the bimodal temporal microstructure specifying object composition. They looked predominantly to the film whose natural soundtrack was played even though the motions of objects in both films were synchronized with the soundtrack. Experiment 3 assessed infants' sensitivity to temporal synchrony relations. Two films depicting objects of the same composition were presented while the motions of only one of them was synchronized with the appropriate soundtrack. Both
6-month-olds showed evidence of detecting temporal synchrony relations under some conditions. Experiment 4 examined how temporal synchrony and temporal microstructure interact in directing intermodal exploration. The natural soundtrack to one of the objects was played out-of-synchrony with the motions of both. In contrast with the results of Experiment 2, infants at 6 months showed no evidence of detecting a relationship between the film and its appropriate soundtrack. This suggests that the temporal asynchrony disrupted their detection of the temporal microstructure specifying object composition. Results of these studies support on invariant-detection view of the development of intermodal perception. 相似文献

婴儿图式 (baby schema, or Kindchenschema) 是指人们对一系列婴儿特征的一种心理表征, 这些特征包括婴儿所特有的高额头、大眼睛和圆脸蛋等知觉特征。婴儿图式可以诱发人们的积极情绪, 并引起关爱、照顾婴儿的行为, 从而满足个体生存以及繁衍的需要。对婴儿面孔的加工存在性别差异, 女性对婴儿特征比男性更敏感, 原因可能有四种:大脑结构的不同、女性独有的情绪反应、女性生殖激素的影响和早期环境的影响。未来的研究可以进一步揭示婴儿图式的特异性神经机制, 并从性别差异入手, 进一步探讨母爱与婴儿图式的相互作用。 相似文献

Twenty-four (12 males, 12 females) healthy, full-term neonates were exposed to an artificial odorant within the first day after birth for approximately 24 hrs to determine if mere exposure would lead to a subsequent preference for that odor. In choice tests following the treatment period, female infants displayed preferential orientation to the exposure odor. Males, in contrast, displayed no evidence of preference for the exposure odor; rather, they demonstrated a right turning bias regardless of odor location. These data suggest that familiarization with an odor shortly after birth is sufficient for female infants to develop preferential responsiveness to that odor. 相似文献

婴儿客体永久性发展机制的研究 总被引:1,自引:0,他引:1
客体永久性是婴儿早期发展中一项重要的心理能力,本研究以208名8-11个月的婴儿为被试,采用实验法和访谈法探讨了婴儿客体永久性的发展机制及其发展趋势问题。结果表明:1)我国婴儿的爬行与其客体永久性的发展无直接关系,支持了爬行对婴儿客体永久性发展的作用可能来自爬行经验而不是爬行动作的假设:2)我国婴儿的客体永久性随年龄增长而持续发展,提示爬行并不是客体永久性发展的唯一途径,爬行不能发挥作用时,婴儿的客体永久性可以通过其它途径得到发展;3)在8-11个月间,我国婴儿的客体永久性达到了阶段Ⅳ水平,8个月的婴儿已经具备了初步的客体永久性。从发展速度来看,婴儿的客体永久性在8、9个月间发展较为迅速,出现了显著的发展性变化,在9-11个月间没有显著的差异。 相似文献

Meltzoff的“似我”假说认为,婴儿借助“我他对等”认识解读他人行为和心理状态,通过他人间的互动信息推断和调整自身行为。“似我”认识以动作表征为基础,借助第一人称体验建立双向映射,对“似我”之人进行因果推理,由此构成发展路径引导婴儿认识他心。注视追随与模仿两种初级社会学习机制进一步丰富了婴儿对社交关系的理解,使人类学习的渠道突破了自我体验的局限而变得更加多元。 相似文献

Infants' differential vocal response (DVR) towards their mother and a female stranger at 3 months of age has been predominantly investigated as an index of early cognitive functioning. The present study explored the relationship between DVR and different infant and mother indicators of the developing relationship quality in a sample of 23 mother–infant dyads. Mother–infant interactions and stranger–infant interactions were videotaped during home visits when the infants were 3 months old. At the age of 12 months, infants' behaviour was assessed in the Ainsworth's strange situation. In both assessments, mothers noted the infants' behavioural states on 3 successive days. Results revealed a specific relation between DVR and the emotional atmosphere of the early mother–infant interaction. Particularly, DVR was less pronounced in favour of the mother when the mother displayed emotional expressions defined as rejection. DVR is discussed as an index that may indicate both infant emotional engagement and infant cognitive competencies. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

Maternal internalizing symptoms have been linked with child internalizing symptoms, but paternal internalizing difficulties have received little attention. Our aims were to prospectively analyse the simultaneous effect of maternal and paternal internalizing symptoms on child internalizing difficulties, examining gender differences, and to verify the mediating effect of parenting practices and child irritability. The sample included 470 families assessed at child ages 3, 6, 8, and 11. Multi-group structural equation modelling was performed with Mplus8.2. Complete equivalence was found between boys and girls for all paths. Maternal internalizing symptoms at age 3 had an indirect effect on child internalizing symptoms at age 11, via irritability at age 8. Paternal internalizing symptoms at age 3 were not associated with any of the variables under study. Maternal internalizing symptoms and child irritability are targets for intervention in order to prevent child internalizing difficulties. 相似文献
