An alternative view of the mental lexicon   总被引:2,自引:0,他引:2  
An essential aspect of knowing language is knowing the words of that language. This knowledge is usually thought to reside in the mental lexicon, a kind of dictionary that contains information regarding a word's meaning, pronunciation, syntactic characteristics, and so on. In this article, a very different view is presented. In this view, words are understood as stimuli that operate directly on mental states. The phonological, syntactic and semantic properties of a word are revealed by the effects it has on those states.  相似文献

It is widely accepted that the series elastic component (SEC) of muscles and tendons plays an important role in dynamic human movements. Many experiments seem to show that during a pre-stretch movement energy can be stored in the SEC which is re-used during the subsequent concentric contraction. Mechanical calculations were performed to calculate the capacity for muscles and tendons to store elastic energy. The storage of elastic energy in muscle tissue appears to be negligible. In tendons some energy can be stored but the total elastic capacity of the tendons of the lower extremities appears far too small to explain reported advantages of a pre-stretch during jumping and running.Based on literature concerning chemical change and enthalpy production during experiments on isolated muscles, a model is proposed which can explain the advantages of a preliminary counter movement on force and work output during the subsequent concentric contraction. The main advantage of a pre-stretch, as seen in movements like jumping, throwing and running, seems to be to prevent a waste of cross bridges at the onset of a contraction in taking up the slack of the muscle. The model can explain why the mechanical efficiency in running can be much higher than in cycling. A muscle which is stretched prior to concentric contraction can do more work at the same metabolic cost when compared with a concentric contraction without pre-stretch.  相似文献

Any integrated theory of mind and behavior must address the dynamic interaction between neurobiological and sociocultural systems as possible causes for human action. Newer findings within the behavioral neurosciences have pointed to the brain's exceptional plasticity and flexibility and suggest that one's surroundings, including one's cultural environment, may directly influence the way the human nervous system becomes organized. In this paper, a preliminary connectionist model of culture-brain interaction is proposed in an effort to illustrate the possible contribution of cultural factors to the development of the individual human brain.  相似文献

An analysis of vocal stereotypy and therapist fading   总被引:1,自引:0,他引:1  
A functional analysis for a boy with Down syndrome and autism suggested that vocal stereotypy was maintained by automatic reinforcement. The analysis also showed that instructions and noncontingent attention suppressed vocal stereotypy. A treatment package consisting of noncontingent attention, contingent demands, and response cost effectively reduced vocal stereotypy. The treatment package remained effective even when noncontingent attention was removed, making the procedure easier to implement. Also, the presence of the therapist in the room with the participant was faded systematically. After completion of fading, vocal stereotypy remained low during conditions similar to the no-consequence phase of the functional analysis.  相似文献

Past studies of the factor structure of the State-Trait Anxiety Inventory (STAI; Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983) have arrived at various solutions. However, a relatively strong consensus supports a four-factor (State Anxiety Present, State Anxiety Absent, Trait Anxiety Present, and Trait Anxiety Absent) structure of the scale resulting from the combination of item polarity dimensions and the original two factors (State and Trait Anxiety). In this article, we assessed the adequacy of an alternative factor model of STAI data, the two-construct, two-method model, in three large samples using confirmatory factor analysis. The results revealed a statistical advantage of the two-construct, two-method model over the one-factor model, the two-construct factor model, and the four-factor model. We discuss possible interpretational advantages of the two-construct, two-method model of the STAI.  相似文献

Two studies assess attitudes toward the childless life-style. One study uses an unstructured response style in order to determine the motivation for and effects of the decision attributed to the person intending to be childless. The second study assesses the relationship between self-reported attitudes measures. The studies suggest the person selecting the childless life-style may be viewed by others as less well adjusted or misguided in this choice, which is inconsistent with the majority of published data on the childless spouse.  相似文献

This article focuses on ways in which therapists can mamtain vitality in their work with people. Becoming more aware of personal dynamics, particularly of the need for control and power, is essential. To remain open to new theories and approaches avoids the pitfall of professional encapsulation. Experiencing the client as a person not only facilitates empathy but involves therapists in the growth process as well. Developing a tragic awareness of life enables therapists to maintain a sense of awe, wonder, and grace toward the human predicament, thus bringing depth or spirituality to their work.He is also editor of TheHarding Journal of Religion and Psychiatry.  相似文献

Divorce is often accompanied by feelings of guilt toward the former spouse. So far, no scale has been available to measure such feelings. For this purpose, the authors developed the Guilt in Separation Scale (GiSS). Content validity was assured by using experts and lay experts to generate and select items. Exploratory analyses were run on samples of 214 divorced individuals and confirmatory analyses on 458 individuals who were in the process of divorcing. Evidence was provided for the reliability and construct validity of the GiSS. The internal consistency was high (α = .91), as were the 6-month and 12-month test-retest reliabilities (r = .72 and r = .76, respectively). The GiSS was related to shame, regret, compassion, locus of cause of the separation, unfaithfulness, and psychological functioning.

Males taken into police custody for reported spouse abuse (n = 19) and a matched control group (n = 19) were asked to describe the drinking habits of their parents and the extent of intra-family violence witnessed by them as children. The retrospective data were compared to the participant's own present alcohol use and aggressiveness (CTS). Excessive paternal drinking and intra-family violence were recalled significantly more often by the spouse abusers than by the controls. A latent structure model suggested that the accumulated violence history was less well predicted by either paternal violence or present aggressiveness than by the direct and indirect effects related to drinking. Context-specific social learning could explain why the parental drunken violence behavior pattern witnessed by the child was repeated by the adult spouse abuser. Aggr.

This paper outlines two approaches to account for the finding that concepts that are minimally counterintuitive are better remembered than intuitive or maximally counterintuitive concepts. The first approach considers such memory advantages to be a property of the concepts themselves while the second approach emphasizes the role played by the context in which such concepts appear in allowing a reader to make sense of them. The context-based view also suggests that counterintuitive concepts lose their advantages as they become widely accepted and embedded in a cultural milieu. In the new context, ideas with enhanced counterintuitiveness obtain transmission advantages. This ratcheting up of counterintuitiveness helps explain cultural innovation and dynamism. It also allows us to account for the development and spread of complex cultural ideas such as the overly counterintuitive religious concepts including the Judeo–Christian–Islamic conceptions of God.  相似文献
