In speaking and comprehending language, word information is retrieved from memory and combined into larger units (unification). Unification operations take place in parallel at the semantic, syntactic and phonological levels of processing. This article proposes a new framework that connects psycholinguistic models to a neurobiological account of language. According to this proposal the left inferior frontal gyrus (LIFG) plays an important role in unification. Research in other domains of cognition indicates that left prefrontal cortex has the necessary neurobiological characteristics for its involvement in the unification for language. I offer here a psycholinguistic perspective on the nature of language unification and the role of LIFG.  相似文献

Gaining insight into the nature and consequences of people's global self-evaluations (i.e., their self-esteem) has been fraught with difficulty. Nearly 2 decades ago, researchers suggested that such difficulties might be addressed by the development of a new class of measures designed to uncover implicit self-esteem. In this article, we evaluate the construct validity of the 2 most common measures of implicit self-esteem, the Implicit Association Test (IAT) and Name-Letter Test (NLT). Our review indicates that the research literature has not provided strong or consistent support for the validity of either measure. We conclude that both tests are impoverished measures of self-esteem that are better understood as measures of either generalized implicit affect (IAT) or implicit egotism (NLT). However, we suggest that there surely are aspects of self-esteem that people are unwilling or unable to report and suggest a general approach that may allow researchers to tap these unspoken aspects of self-esteem.  相似文献

Although rumination has been proposed to play an important role in the creation of hallucinations, direct empirical tests of this proposal have not yet been performed. Employing a distinction between ruminative and reflective self-consciousness, we set out to test a new model of the relations among rumination, reflection, intrusive thoughts, thought suppression, social anxiety, and hallucination-proneness. This model proposed that rumination would be related to hallucination-proneness through the mediating variable of intrusive thoughts, but that reflection would not be related to hallucination-proneness. The model was tested in a student population (N = 296) using path analyses. A modified version of the model was found to be a good fit to the data, once a direct path from reflection to hallucination-proneness had been added. As hypothesized, rumination was related to hallucination-proneness only indirectly, through the mediating variable of intrusive thoughts. Implications for interventions and future directions for research are considered.  相似文献

Survivors of brain injury or stroke can improve movement ability with intensive, supervised practice. Since the hours of supervised therapy with a physical or occupational therapist are limited, telerehabilitation will enable patients to greatly expand the hours that they practice therapeutic exercises. The Jerusalem TeleRehabilitation System (JTRS) consists of patient and therapist systems plus a central server and database connected via the internet. The system can work in two modes: (1) a cooperative mode in which the therapist and patient are online at the same time, and (2) a stand-alone mode in which the patient uses the system on his own. In both cases, the system will monitor the status and progress of the patient and various parameters of his movement abilities, and prepare reports for the patient and for the therapist. From the clinic, the therapist will be able to change the screen seen by the patient and change the level and types of tasks, as needed. Compared to existing systems, our system will have the following advantages: (1) inexpensive and easy to use; (2) remote monitoring and control of the patient's computer by the therapist in the clinic; (3) more detailed analysis of patient status and progress; (4) a "smart" system which self-adapts to the patient's capabilities in real time, increasing or decreasing the difficulty of the exercise as needed; and (5) a central, international database which, by gathering data on many patients over time, will provide the basis for "smart" therapy and will also facilitate coordinated multicenter research studies.  相似文献

Abstract

Theodor W. Adorno's mature thought can be characterized by the attempt to articulate what he calls a “new categorical imperative after Auschwitz.” By this, Adorno means that theory and praxis must be organized in such a way that the Holocaust does not repeat itself. This article argues that Sándor Ferenczi’s metapsychology is key to understanding Adorno’s attempt to rethink the nature of precisely such a new categorical imperative. One of the key themes of Adorno’s entire corpus is the problem of the “identification with the aggressor” – an idea that originates with Ferenzci rather than, as is commonly thought, Anna Freud. The Ferenczian dimension of Adorno’s thinking becomes particularly clear in Adorno’s thoughts on the question of freedom. In this context, Adorno engages in a psychoanalytically informed critique of the philosophy of freedom and a speculative philosophical critique of psychoanalysis. The fashioning of a “new categorical imperative” after Auschwitz entails a form of education directed towards a new form of Mündigkeit, one oriented towards contradiction, resistance, and a steadfast refusal to “identify with the aggressor.”  相似文献

An integrative approach to human memory is presented in the context of brain asymmetry. The results of psychophysiological investigations suggest that right-hemisphere functioning is closely associated with the limbic system; that association leads to the formation of a polysemantic context. Polysemantic context is determined by multiple interconnections among its elements; each element bears the stamp of the whole context. That context sustains episodic, personal, and emotionally laden memories. Left-hemisphere functioning leads to the formation of a monosemantic context, which is responsible for the maintenance of semantic memories. That distinction--in terms of general organization of material by hemispheres--explains such phenomena as memory disturbances among the very old, the influence of emotions on memory, and confabulations.  相似文献

We present a new modeling framework for recognition memory and repetition priming based on signal detection theory. We use this framework to specify and test the predictions of 4 models: (a) a single-system (SS) model, in which one continuous memory signal drives recognition and priming; (b) a multiple-systems-1 (MS1) model, in which completely independent memory signals (such as explicit and implicit memory) drive recognition and priming; (c) a multiple-systems-2 (MS2) model, in which there are also 2 memory signals, but some degree of dependence is allowed between these 2 signals (and this model subsumes the SS and MS1 models as special cases); and (d) a dual-process signal detection (DPSD1) model, 1 possible extension of a dual-process theory of recognition (Yonelinas, 1994) to priming, in which a signal detection model is augmented by an independent recollection process. The predictions of the models are tested in a continuous-identification-with-recognition paradigm in both normal adults (Experiments 1-3) and amnesic individuals (using data from Conroy, Hopkins, & Squire, 2005). The SS model predicted numerous results in advance. These were not predicted by the MS1 model, though could be accommodated by the more flexible MS2 model. Importantly, measures of overall model fit favored the SS model over the others. These results illustrate a new, formal approach to testing theories of explicit and implicit memory.  相似文献

After a restatement of the isolationism of psychoanalysis from allied disciplines, and an examination of some of the reasons for the diversity of schools of thought and the fragmentation of psychoanalytic knowledge, the author suggests the need to adopt principles of correspondence or external coherence along with those of hermeneutic coherence to validate psychoanalytic hypotheses. Recent developments in neurocognitive science have come to the aid of psychoanalysis in this period of crisis, resulting in the proposition of integrating both areas to form a new paradigm for the construction of the theory of the mind. This emerging paradigm tries to integrate clinical knowledge with neurocognitive science, fi ndings from studies on the process and outcome of psychotherapy, research into the early mother‐infant relationship, and developmental psychopathology. The author examines theoretical‐ technical models based on the concept of drives and of relationships in the light of interdisciplinary fi ndings. He concludes that the relational model has a broad empirical base, except when the concept of drives is discredited. Interdisciplinary fi ndings have led to the positing of the replacement of the Freudian model of drives with a model of motivational systems centred on affective processes. He draws certain conclusions which have a bearing on the technique of psychoanalytic treatment. These arise from the adoption of the new integrated paradigm.  相似文献

Research indicates that selecting a strategy to best exploit a new technology is a complex decision-making process. The task involves making a series of decisions with multiple alternatives, each to be evaluated by multiple criteria whose values have high levels of uncertainty. This paper presents a methodology for modelling a new technology decision using decision trees and an optimizing algorithm. A problem of a mining company considering the adoption of new technology is used to illustrate the decision-making task and modelling methodology. A numerical solution to the case demonstrates the potential of the optimizing technique in strategy selection.  相似文献

The aim of this study was to explore the differences in procedural learning abilities between children with DCD and typically developing children by investigating the steps that lead to skill automatization (i.e., the stages of fast learning, consolidation, and slow learning). Transfer of the skill to a new situation was also assessed. We tested 34 children aged 6–12 years with and without DCD on a perceptuomotor adaptation task, a form of procedural learning that is thought to involve the cerebellum and the basal ganglia (regions whose impairment has been associated with DCD) but also other brain areas including frontal regions. The results showed similar rates of learning, consolidation, and transfer in DCD and control children. However, the DCD children's performance remained slower than that of controls throughout the procedural task and they reached a lower asymptotic performance level; the difficulties observed at the outset did not diminish with practice.  相似文献

CGS 5649 B improves the learning performance of aged rats in a one-way active-avoidance situation. If, under reversed conditions, treated aged rats are also tested for passive avoidance, they show "place learning," which our findings have demonstrated to be typical of young rats. The effects of the substance are not confined to these experimental models nor are they species specific: it also facilitates passive avoidance in mice and social learning in rats. The compound is effective if administered before or immediately after the learning trial.  相似文献

Rats trained to run a shuttle-alleyway for food exhibited exploratory behaviour to a novel visual/tactual stimulus presented in a specific place of the alley. Intermittent presentation of the same stimulus in the same place resulted in reduction of the exploratory activity (habituation), both within and between sessions. The animals also directed exploratory activity to the absence of the previously presented stimulus at the place where the stimulus had been presented before; this latter response also habituated. The presentation (1) of the same stimulus to which the animals had already habituated in another place in the alleyway or when the animals were running in an opposite direction to the previous trials of stimulus presentation, or (2) of another stimulus, resulted, again, in the appearance of exploratory activity. These results lead to the conclusion that the animals code external events, store this information, and use it to detect spatial- and directional-contextual changes and to generate predictions about that specific environment.  相似文献
