Step-path theory of action is used to conceptualize future orientation (FO) as anticipated path characteristics and to derive its function. Study 1 finds that stories written to FO sentences are significantly higher on n Achievement when referring to a young person, while stories written to past orientation sentences tend toward higher scores when referring to an old person. Study 2 finds that extremes on chronological age tend to accentuate these trends. Study 3 supports the “multiplicative rule” for the combination of subjective probabilities of success (Ps) along a contingent path for group data. Individual data show that the predicted accentuation of achievement motivation is mediated by a decrease in path length for nonmultipliers of Ps (time FO), and by an increase in path length for multipliers of Ps (task FO). Path Ps also influences the effects of time and task FO.  相似文献

The aim of this paper is to present the Nyya concept of number in the light of contemporary philosophy and to show that the Frege-Russell concept of number does not contradict the Nyya concept of number but rather supplements it.  相似文献

This article represents an attempt to provide an adequate theoretical basis for the development of guidance programs. Three important questions essential to any planning of guidance programs are discussed: (1) scope of responsibility, (2) developmental timing, and (3) focus of guidance activity. A model is proposed in an attempt to conceptualize the relationship between these three important questions of emphasis. The basic problem of the purpose of guidance programs is discussed, and a proposal relevant to the model and the assumed purposes is made. The proposed objective focuses on the environment of the learner, in an effort to prepare him to actively and effectively appropriate and apply new knowledge and skills. The implications that such an objective has for the role of the guidance specialist, as well as for education in general, are discussed.  相似文献

Three asymmetries in the dynamics of 1:2 interlimb coordination were examined: the asymmetry in uncoupled frequencies, the asymmetry in coupled frequencies, and the left-right functional asymmetry of the body. In a bimanual 1:2 task, participants (N = 8) oscillated hand-held pendulums whose uncoupled frequencies were adjusted so that the first kind of asymmetry could be manipulated. For any given pendulum pair, the pendulum assuming the faster motion in the 1:2 coordination was oscillated in the right and the left hands. By assigning combinations of uncoupled eigenfrequencies and coupled task-specified frequencies across hands, the authors studied the interaction of all 3 asymmetries. The results confirm the appropriateness of generalized relative phase as a collective variable for 1:2 coordination. Additionally, they suggest that the generalized form of the detuning parameter represents the first asymmetry and that the coupling function expresses the second asymmetry. In 1:2 coordination, the body's functional asymmetry plays a limited role.  相似文献

Interlimb rhythmic movements can be modeled as coupled oscillators, with stable performance characterized by the relative phase between the limbs. In the present study, that modeling strategy, verified previously for 1:1 coordination, was generalized to 1:2 coordination with a view to n:m coordination. The generalized model predicted interactions between coordination (specifically, 1:1 vs. 1:2) and the frequency asymmetry between the limbs determining mean relative phase and its variability. The predicted interactions were evaluated with bimanual 1:2 and 1:1 rhythmic tasks in which participants (N = 8) oscillated hand-held pendulums whose uncoupled frequencies could be adjusted so that different interlimb asymmetries were produced. The authors needed new analytic procedures to verify stable 1:2 coordination and to resolve stochastic and deterministic sources of variability in the component oscillations. The major expectations from the generalized model were confirmed, and the implications of additional but unpredicted findings for the modeling of multifrequency behavior are discussed.  相似文献

In an effort to objectify neuropsychologic evaluations, consideration of a patient's emotional behavior has often been neglected. An extensive literature review is undertaken in an effort to document lateralized emotional behaviors commonly found in brain injury populations. This evidence is contrasted with the psychiatric symptoms and lateralized neuropsychologic impairments seen in major depression and schizophrenia. A theoretical model is then proposed that attempts to integrate these functional vs. organic symptoms based upon reciprocal inhibition of lateralized emotional functioning in brain injury and psychiatric disorders. This opponent process model not only seems to account for some of the discrepant findings in the literature, but additionally provides a cogent and useful marker to neurophychologically differentiate neuronal vs. metabolic disorders. The model further suggests new ways of envisioning treatment and recovery from both psychiatric illness and brain injury.  相似文献

Dimensions of alexithymia and their relationships to anxiety and depression   总被引:3,自引:0,他引:3  
Investigators have suggested that alexithymia is a multidimensional construct and that it is responsive to situational stressors. We tested these hypotheses in a sample of 110 freshman medical students. We conducted factor analyses on the Toronto Alexithymia Scale (TAS), the Beck Depression Inventory (BDI), and the state portion of the State-Trait Anxiety Inventory (STAI) and then used LISREL to examine the relationships among the various factors. The results indicated that the TAS consists of several independent dimensions and that the dimensions associated with difficulties identifying and communicating feelings are positively related to depression and anxiety. Thus, the evidence now affirms that alexithymia (as measured by the TAS) is multidimensional and that certain dimensions are state dependent.  相似文献

The role of worry, regret, and perceived risk in preventive health decisions was explored in a longitudinal questionnaire study on influenza vaccination among 428 university employees. The study yielded 3 main findings. First, ratings of anticipated worry and regret were stronger predictors of vaccination than perceived risk and mediated the effect of risk on vaccination. Second, the anticipated level of emotions differed systematically from experienced emotions, such that vaccinated individuals anticipated more regret and less worry than they actually experienced. Third, anticipated and experienced emotions had implications for subsequent vaccination decisions. Those who did not vaccinate in the 1st year but had high levels of worry and regret were likely to be vaccinated the following year.  相似文献

Zhuangzi chooses a butterfly as a metaphor for transformation, a sighted creature whose inherent nature contains, and symbolizes, the potential for transformation from a less valued state to a more valued state. If transformation is not to be valued; if, according to a recent article by Jung Lee, ‘there is no implication that it is either possible or desirable for the living to awake from their dream’, why not tell a story of a mole awakening from a dream? This would be a more perfect story. There would be no point of a mole awakening since (setting aside tactile, olfactory, auditory and taste sensations for the purpose of the example), there is no way to distinguish between the world of the mole's imagination and the real world that is forever unavailable to a mole. In addition, Zhuangzi relates the story of the coming of a great sage in which it is clearly stated that ‘Only at the ultimate awakening shall we know that this is the ultimate dream’. Such textual evidence both from the choice of metaphors and evidential passages indicates that the message of the Zhuangzi is not epistemological relativity, but one of transformation from a state of intellectual blindness to a state of true understanding.  相似文献
