Attentional requirements of walking at various speeds in older adults were examined. Twenty healthy older adults (69.9?±?2.77?years; 8 males) were asked to walk a distance of 10?m at a self-selected speed as well as 30% quicker and 30% slower. Concurrently, reaction time (RT) was evaluated by having participants respond as fast as possible to randomly presented auditory stimuli. Results reveal that an accelerated walking speed generated faster RT than slow and self-selected speeds, while no difference was found between the latter. Faster RTs during an accelerated walking speed may have been precipitated by the reduced equilibrium demands of the task. 相似文献

Subjects (N = 217) rated the attractiveness of 56 general goals and then completed 3 theory-based tests of personality or motivation. Two goal factors—labeled Social-Economic Status and Competitive Achievement—seemed to reflect two broad domains of status-seeking motivation, and two other factors—labeled Growth Orientation and Interpersonal Security—pointed to separate domains of cooperative motivation. Thus, there was confirmation for the widespread assumption of two primary types of interpersonal motivation (solidarity and status) in our culture but also for important distinctions within each type. Canonical and direct correlations with the theoretically-grounded measures strongly supported that interpretation of the factors. Meaningful relationships between factors obtained from the questionnaire and the more rationally-based test scores indicated convergence in mappings of motivational space. 相似文献

Subjects provided free responses to six concepts representing varying degrees of involvement. Responses were obtained from each subject under normal and negative affect conditions. Group data were used. Under negative affect conditions, significant correlations were found between concept involvement and type/token ratio (TTR), tokens per type, response variation index (RVI), and total types. Correlations were in the direction of increased redundancy as involvement decreased and, conversely, increased response variation as involvement increased. These relationships held only under negative affect conditions. Implications were discussed for the problems of communication under negative affect conditions and the assessment of individuals’ internal states from verbal behavior. Finally, a sociolinguistic view of the “language community” concept was offered. 相似文献

The present study is an investigation into how romantic relationship satisfaction and attitudes toward gender stereotypes about romantic relationship and gender are related to future time orientation in romantic relationships (FTORR). Four hundred and thirteen (208 men and 205 women) university students taking elective psychology courses at Middle East Technical University were given a scale including items about FTORR, romantic relationship satisfaction, and attitudes toward gender stereotypes about romantic relationships. All the participants were then involved in a heterosexual romantic relationship. Multiple regression results showed that for the women, attitudes toward men's assertiveness and men's dominance in relationships were more important predictors of FTORR than relationship satisfaction. For the men, attitudes toward men's assertiveness and romantic relationship satisfaction were important predictors of FTORR, but attitude toward men's dominance was not a predictor of FTORR. Women were more future oriented in their ongoing romantic relationships than were men. Finally, participants who were highly satisfied with their relationships scored higher on FTORR than those who were less satisfied. 相似文献

The aim of this study was to identify the cascade of effects leading from alterations in force generation around the ankle joint to increased plantar pressures under the forefoot. Gait analysis including plantar pressure measurement was performed at an individually preferred and a standardized, imposed gait velocity in diabetic subjects with polyneuropathy (n = 94), without polyneuropathy (n = 39) and healthy elderly (n = 19). The plantar flexion moment at 40% of the stance phase was negatively correlated with the displacement rate of center of pressure (r = ?.749, p < .001 at the imposed, and r = ?.693, p < .001 at the preferred gait velocity). Displacement rate of center of pressure was strongly correlated with forefoot loading (r = ?.837, p < .001 at the imposed, and r = ?.731, p < .001 at the preferred gait velocity). People with a relatively high plantar flexion moment at 40% of the stance phase, have a faster forward transfer of center of pressure and consequently higher loading of the forefoot. This indicates that interventions aimed at increasing the control of the roll-off of the foot may contribute to a better plantar pressure distribution. 相似文献

The notion of time is traced both in Philosophy and in Physics (Newtonian Mechanics, Relativity, Cosmology, Quantum Theory). Distinct temporalities emerge and time appears as the essential condition for the realization of being, in accordance with ideas and theories developed by Peirce, Whitehead, and Heidegger. 相似文献

Because the definition of behavior changes as our understanding of behavior changes, giving a final definition is impossible. One can, however, rule out some possibilities and propose some others based on what we currently know. Behavior is not simply movement, but must be defined by its function. Also, our understanding of behavior must agree with evolutionary theory. I suggest 4 basic principles: (a) only whole organisms behave; (b) behavior is purposive; (c) behavior takes time; and (d) behavior is choice. Saying that parts of an organism behave is nonsense, and, moreover, evolutionary theory explains the existence of organisms mainly through their adaptive behavior. Behavior is purposive in that behavior is shaped by its consequences, through an organism''s lifetime or through interactions with the environment across many generations of natural selection. Behavior takes time in that behavior is interaction with the environment that cannot take place at a moment. Moreover, at a moment in time, one cannot definitely identify the function of behavior. Identification of an activity requires a span of time. Behavior is choice in the sense that a suitable span of time always includes time spent in more than 1 activity. Activities include parts that are themselves activities on a smaller time scale and compete for time. Thus, behavior constitutes time allocation. An accounting problem arises whenever any behavior is attributed to multiple consequences. In the molar multiscale view, this raises the question of whether 2 activities can occur at the same time. The question remains open. 相似文献

We examined the consequences of personal savings estimate inflation that occurs when decision makers provide savings estimates for specific future months when compared with the next month or the next year time frames, along with a method to attenuate this bias. The results of three experiments showed that the savings estimate inflation leads to significantly larger estimates of desired nest egg size (Experiment 1) and preference for riskier choices in other financial domains such as investment and employment decisions (Experiment 2). An attempt to attenuate this bias revealed that it is corrected when individuals provide a budgeting estimate prior to giving a savings estimate (Experiment 3). The theoretical and practical implications of the findings are discussed. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Intertemporal tradeoffs are ubiquitous in decision making, yet preferences for current versus future losses are rarely explored in empirical research. Whereas rational‐economic theory posits that neither outcome sign (gains vs. losses) nor outcome magnitude (small vs. large) should affect delay discount rates, both do, and moreover, they interact: in three studies, we show that whereas large gains are discounted less than small gains, large losses are discounted more than small losses. This interaction can be understood through a reconceptualization of fixed‐cost present bias, which has traditionally described a psychological preference for immediate rewards. First, our results establish present bias for losses—a psychological preference to have losses over with now. Present bias thus predicts increased discounting of future gains but decreased (or even negative) discounting of future losses. Second, because present bias preferences do not scale with the magnitude of possible gains or losses, they play a larger role, relative to other motivations for discounting, for small magnitude intertemporal decisions than for large magnitude intertemporal decisions. Present bias thus predicts less discounting of large gains than small gains but more discounting of large losses than small losses. The present research is the first to demonstrate that the effect of outcome magnitude on discount rates may be opposite for gains and losses and also the first to offer a theory (an extension of present bias) and process data to explain this interaction. The results suggest that policy efforts to encourage future‐oriented choices should frame outcomes as large gains or small losses. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献
