We compare fork arrow logic, an extension of arrow logic, and its natural first-order counterpart (the correspondence language)
and show that both have the same expressive power. Arrow logic is a modal logic for reasoning about arrow structures, its
expressive power is limited to a bounded fragment of first-order logic. Fork arrow logic is obtained by adding to arrow logic
the fork modality (related to parallelism and synchronization). As a result, fork arrow logic attains the expressive power
of its first-order correspondence language, so both can express the same input–output behavior of processes. 相似文献
Using a name-based categorization task, Nazzi found in 2005 that French-learning 20-month-olds can make use of one-feature consonantal contrasts between new labels but fail to do so with one-feature vocalic contrasts. This asymmetry was interpreted as developmental evidence for the proposal that consonants play a more important role than vowels at the lexical level. In the current study using the same task, we first show that by 30 months French-learning infants can make use of one-feature vocalic contrasts (e.g., /pize/–/pyze/). Second, we show that in a situation where infants must neglect either a consonantal one-feature change or a vocalic one-feature change (e.g., match a /pide/ with either a /tide/ or a /pyde/), both French- and English-learning 30-month-olds choose to neglect the vocalic change rather than the consonantal change. We argue that these results suggest that by 30 months of age, infants still give less weight to vocalic information than to consonantal information in a lexically related task even though they are able to process fine vocalic information. 相似文献
Freud introduced the concept of psychical reality as a consequence of abandoning the theory of seduction, and although this meant a turning point in his theoretical thinking he never defined the concept concisely and systematically. Thus it is possible to delineate at least two meanings of psychical reality that run through Freud´s writings as well as the writings of contemporary analysts. On the one hand psychical reality encompasses the whole field of subjective experiences. On the other, it is understood more narrowly as a transformation of experiences in the unconscious.
Substituting the idea of different meanings ascribed to Freud´s concept this article proposes to differentiate between levels in the psyche with the main focus on the unconscious level of the dream and of phantasy and the real unconscious. Starting from the most superficial level of subjective reality the text moves to that of fantasy formation illustrated by primarily Freud´s text on `A child is being beaten´. Adding Laplanche´s translational model the article ends up at the deepest level represented by the late Lacan and his concept of the real Unconscious.
The paper concludes that the term real points to something exceeding symbolization and the imaginary—thus escaping comprehension—and yet is absolutely indispensable to the organization of unconscious processes. 相似文献
This article has the intention of giving impulses to a hopefully more creative and open-minded discussion of the function of training analysis and the kind of training model we seem to take for granted in the Scandinavian countries, the Eitingon model. I will consider some historical background data on this model as well as some historical data on the development in France which have created an alternative model of training. Especially in Sweden, there has been a stormy debate during the last years about the training analyst functions and some members have actually decided to leave our association because of this. I would like to try to shift focus from just a ‘yes-or-no-perspective’? to a broader question of our psychoanalytical society’s purpose and structure and how the training-model could sustain it. 相似文献
