The locomotor adjustment induced by step perturbation of human subjects walking on a treadmill was described by a quantitative analysis of the EMG activities of selected trunk and leg muscles and by rotations of leg joints. The role of the proprioceptive input in the EMG reaction was also evaluated. The perturbation was obtained by a rapid and unexpected increase of belt speed. The motor response showed the stereotyped characteristics of a motor automatism and was accomplished without affecting the basic motor pattern of the gait. The EMG adjustment showed short-latency reflex responses (40–60 msec) of muscles acting at the joints more directly affected by the perturbing stimulus. This result supports the hypothesis of a spinal neuronal mechanism involved in the rapid adjustment of gait. The activity of primary spindle afferents seems to play an important role in the production of the faster EMG responses. 相似文献

According to the received view, Charles S. Peirce's theory of diagrammatic reasoning is derived from Kant's philosophy of mathematics. For Kant, only mathematics is constructive/synthetic, logic being instead discursive/analytic, while for Peirce, the entire domain of necessary reasoning, comprising mathematics and deductive logic, is diagrammatic, i.e. constructive in the Kantian sense. This shift was stimulated, as Peirce himself acknowledged, by the doctrines contained in Friedrich Albert Lange's Logische Studien (1877). The present paper reconstructs Peirce's reading of Lange's book, and illustrates what, according to Peirce, was right and what was problematic in Lange's account of reasoning. It further seeks to explain how Peirce's theory of deductive reasoning was a combination of Kant's philosophy of mathematics and Lange's philosophy of logic. 相似文献

Black people are widely negatively stereotyped. The presence of unconscious stereotypes can be effectively assessed with the administration of “racial priming tasks.” An ethnically diverse group was subjected to a priming paradigm to test whether racial cues could bias the identification of target objects. Participants were asked to categorize objects (either as dangerous or nondangerous) after the presentation of Black/White faces as primes. Results show that both Black and White participants were faster in categorizing dangerous objects when primed with Black faces compared to the control condition (i.e., scrambled faces). One possible explanation for this effect is that Black faces are generally associated with a feeling of danger, which ultimately leads to faster responses. 相似文献

The aims of the present study are to evaluate the impact of insomnia on psychological well-being and to examine the associations of insomnia and psychological well-being with anxiety and depression. Forty-one patients attending our hospital-based Centre for sleep medicine were administered scales for the evaluation of insomnia (ISI), anxiety (STAI-Y), depression (BDI-II) and psychological well-being (PWB). The scores were compared to those of a control group of 68 subjects attending the hospital for routine examinations or as accompanying persons. Significant differences between patients and controls were detected for anxiety and depression, as well as for psychological well-being. Even if subclinical on average, anxiety and depression symptoms were significantly related to poor psychological well-being, whereas insomnia per se was not. These findings suggest that patients with insomnia report a relevant impact on their psychological well-being, and that such an impact seems to be strongly associated with concomitant subthreshold symptoms of anxiety and depression. The implications for diagnosis and treatment are discussed. 相似文献

In this paper I discuss and try to remove some major stumbling blocks for a Moorean buck-passing account of reasons in terms of value (MBP): There is a pro tanto reason to favour X if and only if X is intrinsically good, or X is instrumentally good, or favouring X is intrinsically good, or favouring X is instrumentally good. I suggest that MBP can embrace and explain the buck-passing intuition behind the far more popular buck-passing account of value, and has the means to avoid the wrong kind of reasons problem. Further, I counter the common suspicion that a Moorean account cannot make sense of deontological views such as Ross’s, and that it generally leaves no room for agent-relative reasons. In order to do this, I appeal to the idea that a Moorean account does not dictate the substantive view that values have to be maximized. In some cases, expressing them might be a better response. Finally I lay out and reply to a potentially devastating argument to the effect that a Moorean account makes oughts and reasons non-normative. I also criticize Scanlon’s attempt to favour his own buck-passing account via consideration of the open question argument. MBP thus emerges as a live option in the buck-passing debate. 相似文献
