When do infants start to understand that they can grasp an object by its handle when the interesting part is out of reach? Whereas it is known from preferential looking tasks that already at three months of age infants show surprise when all parts of an object do not move together, little is known about when infants are able to use such knowledge in an active grasp situation. To answer this question we presented six, eight, and 10 month-old infants in a cross-sectional and a longitudinal study with a white cardboard handle within reach and a bright ball at the end of the handle and out of reach. A trick condition, where the handle and the ball seem attached but were not, was added to get an indication of the infant's expectation by observing a possible surprise reaction.Results show that 6-month-olds’ most frequent first behaviors consisted in pointing toward the ball without grasping the handle, or grasping the handle without looking at the ball until it moved. In addition, they often did not look surprised in the trick condition. Eight- and 10-month-olds most often grasped the handle while looking at the ball, and showed clear surprise in the trick condition. This was interpreted as showing that around eight or 10 months, infants take a significant step in understanding the cohesiveness of composite objects during grasping. 相似文献

AbstractSince the 1980s, numerous laboratory investigations have been arguing that infants are numerically competent. This work presents a critical review of this line of research. We propose that despite the repertoire of numerical abilities attributed to infants and the seemingly natural character of the very first numbers in the numerical series, the semiotic complexity of their use and comprehension poses a cognitive challenge that children undertake, motivated, supported and often guided by others. This challenge involves a high degree of semiotic organization of the material world as well as an ability to manage early sign systems, systems which children learn how to use during their first years of life and which form the platform on which numbers are based. 相似文献

Metapsychology or metapsychologies? Some comments on Paul Denis's paper ‘The drive revisited: mastery and satisfaction’ 下载免费PDF全文
Gabriel Sapisochin 《The International journal of psycho-analysis》2016,97(3):797-809
In this commentary on Paul Denis's paper ‘The drive revisited: mastery and satisfaction’, the author defends the idea of a plurality of metapsychologies that must be contrasted with and distinguished from each other while avoiding incompatible translations between models. In this connection he presents various theoretical approaches to aggression and the death drive, and demonstrates the differences between the drive model and the model underlying the theory of internalized object relations. The author holds that the concept of the internal object differs from Freud's notion of the representation (Vorstellung). He also considers that the imago as defined by Paul Denis in fact corresponds to the concept of the internal object. Lastly, he addresses the complex issue of listening to archaic forms of psychic functioning and their non‐discursive presentation within the analytic process, which affects the transference‐countertransference link. 相似文献

Destruction reconceived: On Winnicott's ‘The Use of an Object and Relating through Identifications’ 下载免费PDF全文
Thomas H. Ogden 《The International journal of psycho-analysis》2016,97(5):1243-1262
‘The Use of an Object and Relating through Identifications’ is a landmark contribution that I find very difficult to write about because so much of what lies at its core is merely suggested. It is necessary for the reader not only to read the paper, but also to write it. In my reading/writing of the paper, the mother becomes real for the infant in the process of his actually destroying her as an external object (destroying her sense of herself as an adequate mother), and his perceiving that destruction. She also becomes a real external object for the infant in the process of his experiencing the psychological work involved in surviving destruction, a form of work that does not occur in the world of fantasied objects. The analyst or mother may not be able to survive destruction. It is essential that the analyst be able to acknowledge to himself his inability to survive and, if necessary, to end the analysis because of the very damaging effects for both patient and analyst of prolonged experience of this sort. The author presents clinical discussions of analyses in which the analyst survives destruction and is unable to survive destruction. 相似文献

In the present study we examined whether higher levels of object imagery, a stable characteristic that reflects the ability and preference in generating pictorial mental images of objects, facilitate involuntary and voluntary retrieval of autobiographical memories (ABMs). Individuals with high (High-OI) and low (Low-OI) levels of object imagery were asked to perform an involuntary and a voluntary ABM task in the laboratory. Results showed that High-OI participants generated more involuntary and voluntary ABMs than Low-OI, with faster retrieval times. High-OI also reported more detailed memories compared to Low-OI and retrieved memories as visual images. Theoretical implications of these findings for research on voluntary and involuntary ABMs are discussed. 相似文献

While the objects of olfaction are intuitively individuated by reference to the ordinary objects from which they arise, this intuition does not accurately capture the complex nature of smells. Smells are neither ordinary three-dimensional objects, nor Platonic vapors, nor odors. Rather, smells are the molecular structures of chemical compounds within odor plumes. Molecular Structure Theory is offered as an account of smells, which can explain the nature of the external object of olfactory perception, what we experience as olfactory objects, and what determines the olfactory quality of smells by which we can demarcate the spatiotemporal boundaries of smells. 相似文献

In the first year of life, the ability to search for hidden objects is an indicator of object permanence and, when multiple locations are involved, executive function (i.e. inhibition, cognitive flexibility and working memory). The current study was designed to examine attentional predictors of search in 5‐month‐old infants (as measured by the looking A‐not‐B task), and whether levels of maternal education moderated the effect of the predictors. Specifically, in a separate task, the infants were shown a unique puppet, and we measured the percentage of time attending to the puppet, as well as the length of the longest look (i.e., peak fixation) directed towards the puppet. Across the entire sample (N = 390), the percentage of time attending to the puppet was positively related to performance on the visual A‐not‐B task. However, for infants whose mothers had not completed college, having a shorter peak looking time (after controlling for percentage of time) was also a predictor of visual A‐not‐B performance. The role of attention, peak fixation and maternal education in visual search is discussed. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
