Using automated controlled rearing to explore the origins of object permanence

What are the origins of object permanence? Despite widespread interest in this question, methodological barriers have prevented detailed analysis of how experience shapes the development of object permanence in newborn organisms. Here, we introduce an automated controlled‐rearing method for studying the emergence of object permanence in strictly controlled virtual environments. We used newborn chicks as an animal model and recorded their behavior continuously (24/7) from the onset of vision. Across four experiments, we found that object permanence can develop rapidly, within the first few days of life. This ability developed even when chicks were reared in impoverished visual environments containing no object occlusion events. Object permanence failed to develop, however, when chicks were reared in environments containing temporally non‐smooth objects (objects moving on discontinuous spatiotemporal paths). These results suggest that experience with temporally smooth objects facilitates the development of object permanence, confirming a key prediction of temporal learning models in computational neuroscience.     

Children's scale errors: A by‐product of lexical development?

Scale errors occur when young children seriously attempt to perform an action on an object which is impossible due to its size. Children vary substantially in the incidence of scale errors with many factors potentially contributing to these differences, such as age and the type of scale errors. In particular, the evidence for an inverted U‐shaped curve of scale errors involving the child's body (i.e., body scale errors), which would point to a developmental stage, is mixed. Here we re‐examine how body scale errors vary with age and explore the possibility that these errors would be related to the size and properties of children's lexicon. A large sample of children aged 18–30 months (N = 125) was tested in a scale error elicitation situation. Additionally, parental questionnaires were collected to assess children's receptive and expressive lexicon. Our key findings are that scale errors linearly decrease with age in childhood, and are more likely to be found in early talkers rather than in less advanced ones. This suggests that scale errors do not correspond to a developmental stage, and that one determinant of these errors is the speed of development of the linguistic and conceptual system, as a potential explanation for the individual variability in prevalence.     

Self‐generated variability in object images predicts vocabulary growth

Object names are a major component of early vocabularies and learning object names depends on being able to visually recognize objects in the world. However, the fundamental visual challenge of the moment‐to‐moment variations in object appearances that learners must resolve has received little attention in word learning research. Here we provide the first evidence that image‐level object variability matters and may be the link that connects infant object manipulation to vocabulary development. Using head‐mounted eye tracking, the present study objectively measured individual differences in the moment‐to‐moment variability of visual instances of the same object, from infants’ first‐person views. Infants who generated more variable visual object images through manual object manipulation at 15 months of age experienced greater vocabulary growth over the next six months. Elucidating infants’ everyday visual experiences with objects may constitute a crucial missing link in our understanding of the developmental trajectory of object name learning.     

Understanding the weapon focus effect: The role of threat,unusualness, exposure duration,and scene complexity

We examined the role of exposure duration and scene complexity on the weapon focus effect (WFE). Memory for the mock crime was affected more by a weapon than an unusual but nonthreatening object. Threat reduced correct identifications when the event was short but not long; duration of the event did not interact with unusualness. Additionally, we found a WFE for target‐absent lineup decisions, but only for the accomplice lineup, not the object‐wielding perpetrator's lineup. We discuss the implications of these results for illuminating the mechanisms that elicit the WFE.     

多目标追踪中基于运动信息的分组效应

本研究旨在探讨运动信息对多目标追踪的影响, 具体为考察多目标追踪中是否存在基于运动信息的分组效应, 以及不同类型表面特征(颜色和形状)对这一效应的影响。实验1发现多目标追踪中存在基于运动信息的分组效应, 并且这一分组效应是自动化的。实验2和实验3分别在不同颜色和不同形状组合条件下考察了基于运动信息的分组效应的稳定性, 结果都表明不同表面特征的组合不会干扰基于运动信息的分组效应的形成, 但其效应量都因表面特征的出现而缩减。整体而言, 多目标追踪中存在基于运动信息的自动化分组效应, 并且这一效应是格式塔法则中共同命运律的具体表现, 能稳定存在于不同表面特征组合之间。     

客体表征质量在语义客体注意效应中的作用

已有研究表明,除自下而上因素外,自上而下因素也能够对客体知觉起到调节作用,从而影响注意的分配。本研究以不同词频（高频和低频）的汉语双字词为实验材料,采用双矩形线索范式变式考察不同语义客体表征质量对基于语义客体注意效应的影响。结果发现,在高语义客体表征质量的条件下出现了基于语义客体的注意效应,而在低语义客体表征质量的条件下并未出现基于语义客体的注意效应。该结果表明,语义客体表征质量的高低是影响基于语义客体注意效应的重要因素。     

汉语主动句、被动句的命题表征项目顺序特点

以中国大学生为被试,采用句子—图画验证任务(sentence-picture verification task )探讨了中国学生理解汉语主动句、被动句所形成的命题表征中项目顺序特点。结果表明,无论是语义水平较高的不可逆句,还是语义水平较低的可逆句,中国学生理解汉语主动句、被动句所建构的命题表征中项目顺序均为“施事→受事”。本研究结果初步表明,中国学生理解汉语主动句和被动句时,能根据它们不同的表层结构（汉语主动句的语言表达顺序为“施事→受事”、汉语被动句的语言表达顺序为“受事→施事”）建构相同的深层结构（语义内容的命题表征项目顺序“施事→受事”）,可能是一个按照“施事→受事”固定方向进行的系列认知心理加工的过程     

环境污染对中枢神经系统损伤的哲学思考

随着工农业生产的迅速发展,全球环境污染日趋严重,由此引发了环境污染对健康影响的思考。环境污染问题从各个方面影响着人类的健康,尤其是它对人类中枢神经系统地损伤已成为人们对健康关注的重点之一。本文运用矛盾自然观的哲学观点,对环境污染对中枢神经系统的损伤做出阐述和几点思考。     

Nonseparability,Potentiality, and the Context-Dependence of Quantum Objects

Standard quantum mechanics undeniably violates the notion of separability that classical physics accustomed us to consider as valid. By relating the phenomenon of quantum nonseparability to the all-important concept of potentiality, we effectively provide a coherent picture of the puzzling entangled correlations among spatially separated systems. We further argue that the generalized phenomenon of quantum nonseparability implies contextuality for the production of well-defined events in the quantum domain, whereas contextuality entails in turn a structural-relational conception of quantal objects, viewed as carriers of dispositional properties. It is finally suggested that contextuality, if considered as a conditionalization preparation procedure of the object to be measured, naturally leads to a separable concept of reality whose elements are experienced as distinct, well-localized objects having determinate properties. In this connection, we find it necessary to distinguish the meaning of the term reality from the criterion of reality for us. The implications of the latter considerations for the notion of objectivity in quantum mechanics are also discussed.

文化与心理治疗

关于文化与心理治疗的关系,主要有文化相对论与文化中立论两种观点。它们各有一定的积极之处和局限性。其实,心理治疗具有普遍性与特殊性两种属性。因此,应注意对心理与行为异常及其治疗的文化分析;积极挖掘整理本文化心理治疗的理论与方法,实现心理治疗的本土化或文化化;加强心理治疗理论与方法的文化整合。
