Through direct observation of infants and mothers in an "experimental" nursery, Mahler and her associates have accumulated data which when analyzed point to distinct phases (stages) during the long process of the development of the concepts of self and object. These phases, autism, symbiosis, and separation-individuation (itself subdivided into four subphases, differentiation, practicing, rapprochement, and consolidation of individuation) correspond well with the stages described by Piaget as constituting the period of cognitive growth described as sensorimotor intelligence. The intercorrelation of the phasic development along these two separate lines (objectal-affective and cognitive), expectable as it may be, is of considerable interest as it underlines the intrinsic strength of the psychoanalytic concept of the object. Furthermore, this intercorrelation enhances and enlarges our understanding of the process of consolidation of self and object during the first years of life.  相似文献

Research in the cognitive dissonance tradition has shown that choosing between two equally attractive alternatives leads to more favorable evaluations of chosen as compared to rejected alternatives (spreading-of-alternatives effect). The present research tested associative self-anchoring as an alternative mechanism for post-decisional changes of implicit evaluations. Specifically, we argue that choosing an object results in the creation of an association between the chosen object and the self. By virtue of this association, implicit evaluations of the self tend to transfer to the chosen object, such that implicit evaluations of the chosen object depend on implicit evaluations of the self. Importantly, this mechanism can lead to ownership-related changes in implicit evaluations even in the absence of cognitive dissonance. Results from four experiments provide converging evidence for these assumptions. Implications for a variety of phenomena are discussed, including cognitive dissonance, the mere ownership effect, the endowment effect, and ingroup favoritism.  相似文献

Recognizing opportunities to achieve pending goals is an important cognitive ability. But when and how do we recognize that a current situation is especially suited to resuming a past goal? The predictive encoding model suggests pending goals are encoded into memory in association with anticipated environmental features. Optimally, these features are (a) necessary for successful goal satisfaction, (b) distinctive preconditions for expecting a plan to achieve the goal, and (c) described so as to be readily identified in the environment. Later, ordinary perception of features in the environment leads to automatic recognition of opportunities already prepared in memory. Evidence from experimental studies supports this theory, and demonstrates that general preparation can produce apparently novel opportunism. These findings suggest ways to facilitate the recognition of opportunities to satisfy pending goals.  相似文献

This article presents an understanding of the Rorschach Technique in terms of emergent models from cognitive science. We propose a linkage between cognitive psychology and neuropsychology in understanding the operations that underlie the Rorschach response process. Contemporary information processing models are described. The Rorschach Technique is conceived of as a complex process involving all areas of the cerebral hemispheres, encompassing various aspects of visual attention and perception, object recognition, associative memory, language production, and executive functioning. Exner's model of the response process is delineated, including both Association and Inquiry phases, in terms of requisite underlying neuropsychological abilities and anatomical substrates. The question of the Rorschach Technique's status, utility, and potential as a neuropsychological assessment, tool is discussed. Understanding the Rorschach in terms of contemporary cognitive psychological and neuropsychological models heightens appreciation of the technique's complexity and provides a heuristic and conceptual foundation for empirical research.  相似文献

The binding problem is considered in terms of how a brain-inspired cognitive system can recognize multiple sensory features from an object which may be among many objects, process those features individually and then bind the multiple features to the object they belong to. The Causal Cognitive Architecture 3 (CCA3) is a brain-inspired cognitive architecture using a multi-dimensional navigation map as its basic store of information, and capable of pre-causal as well as fully causal behavior. Objects within an input sensory scene are segmented, and sensory features (e.g., visual, auditory, etc.) of each segmented object are spatially mapped onto a variety of navigation maps. It is shown that to provide efficient, flexible, causal solutions to real-world problems, it is not sufficient to bind space (i.e., objects spatially) but it is necessary to also bind time (i.e., change and rate of change of objects within a sensory scene). The CCA3 binds both space and time onto a navigation map as physical features, and is better able to function in real-world environments. As the CCA3 is brain-inspired, the Causal Cognitive Architecture can help to better hypothesize and understand biological mammalian brain function, including solutions to the binding problem. The CCA3 architecture allows it to work in different knowledge domains, possess continual lifelong learning, and demonstrate reasonable explainability.  相似文献

Greg Davis 《Visual cognition》2013,21(3-5):411-430
Many previous studies have found that we can attend pairs of visual features (e.g., colour, orientation) more efficiently when they belong to the same “object” compared to when they belong to separate, neighbouring objects (e.g., Behrmann, Zemel, & Mozer, 1998; Egly, Rafal, & Driver, 1994). This advantage for attending features from the same object may reflect stronger binding between these features than arises for pairs of features belonging to separate objects. However, recent findings described by Davis, Welch, Holmes, and Shepherd (in press) suggest that under specific conditions this same-object advantage can be reversed, such that attention now spreads more readily between features belonging to separate neighbouring objects than between features of the same object. In such cases it would appear that features belonging to separate visual objects are more strongly bound than features of the same object. Here I review these findings and present the results of a new study. Together these data suggest that magnocellular processes in the human visual system bind together features from separate objects, whereas parvocellular processes bind together features from the same object.  相似文献

A mood induction paradigm was used to examine dysphoria-related changes in two types of cognitive processing in individuals who had previously experienced depression. Formerly depressed patients (n = 23) and never-depressed controls (n = 27) completed the Dysfunctional Attitudes Scale, a self-report measure of effortful processing, and performed the Implicit Association Test, an automatic-reaction time task that measures evaluative bias, before and after a negative-mood induction. The formerly depressed group showed both an increase in endorsement of dysfunctional attitudes and a more negative evaluative bias for self-relevant information after the induction, relative to controls--however, there was no association between the mood-linked changes observed on these two measures. The shift in evaluative bias shown by the formerly depressed group was similar to that seen in a group of 32 currently depressed individuals. These findings suggest that even a mild negative mood in formerly depressed individuals can reinstate some of the cognitive features observed in depression itself.  相似文献
