The authors used two analyses developed within the framework of the uncontrolled manifold hypothesis to quantify multimuscle synergies during voluntary body sway: analysis of intertrial variance and analysis of motor equivalence with respect to the center of pressure (COP) trajectory. Participants performed voluntary sway tasks in the anteroposterior direction at 0.33 and 0.66 Hz. Muscle groups were identified in the space of muscle activations and used as elemental variables in the synergy analyses. Changing mechanical and vision feedback–based constraints led to significant changes in indices of sway performance such as COP deviations in the uninstructed, mediolateral direction and indices of spontaneous postural sway. In contrast, there were no significant effects on synergy indices. These findings show that the neural control of performance and of its stability may involve different control variables and neurophysiological structures. There were strong correlations between the indices of motor equivalence and those computed using the intercycle variance analysis. This result is potentially important for studies of patients with movement disorders who may be unable to perform multiple trials (cycles) at any given task, making analysis of motor equivalence of single trials a viable alternative to explore changes in stability of actions. 相似文献

This paper argues that the accuracy of perceptual experiences cannot be properly characterized by using the particular notion of content without breaking one of the three plausible assumptions. On the other hand, the general notion of content is not threatened by this problem. The first assumption is that all elements of content determine the accuracy conditions of an experience. The second states that objects needed for the accuracy of experiences are physical entities that stand in a perceptual relation to a subject. According to the third assumption, common experiences do not have accuracy conditions that are impossible to satisfy. The above point is demonstrated by analysing illusions of identity in which the number of objects is represented incorrectly. In the concluding parts of the paper, I investigate how an alternative account of particular content can be developed by rejecting the first assumption. 相似文献

The role of activation (arousal and subjective significance) was investigated for word processing in an explicit emotional judgement task using a 3?×?3 manipulation. We expected to find dissociative effects for both factors. The behavioural results showed that the fraction of words perceived as emotional increases with increasing arousal or subjective significance. The electrophysiological (EEG) results showed that both factors influence ERP amplitudes. General effects of subjective significance were found for early (60–120?ms and 120–250?ms, low subjective significant stimuli evoked higher amplitude than other conditions) and late (350–490?ms, high subjective significant stimuli evoked higher amplitude than other conditions) time ranges. Localised arousal effects were found in 250–350?ms and 350–490?ms time ranges at posterior (amplitude for high arousing stimuli was less positive than for other conditions) and left frontal ROIs (diverse pattern). Localised subjective significance effects were found for the 350–490?ms time range at the posterior ROIs (amplitude for high subjective significant stimuli was more positive than for other conditions). The results of this study suggest that the effects of arousal reported in earlier studies might account for a more complex form of activation that was recently postulated, namely subjective significance. 相似文献

Conspiracy theories offer simple answers to complex problems by providing explanations for uncertain situations. Thus, they should be attractive to individuals who are intolerant of uncertainty and seek cognitive closure. We hypothesized that need for cognitive closure (NFCC) should foster conspiracy beliefs about events that lack clear official explanations, especially when conspiracy theories are temporarily salient. In Experiment 1, NFCC positively predicted the endorsement of a conspiracy theory behind the refugee crisis, especially when conspiratorial explanations were made salient. Experiment 2 showed that when conspiratorial explanations were made salient, NFCC positively predicted beliefs in conspiracies behind a mysterious plane crash. However, the link between NFCC and beliefs in conspiratorial explanations was reversed in the case of a plane crash with an official, non‐conspiratorial, explanation for the accident. In conclusion, people high (vs. low) in NFCC seize on conspiratorial explanations for uncertain events when such explanations are situationally accessible. 相似文献

The domain of a quantifier is determined by a variety of factors, which broadly speaking fall into two types. On the one hand, the context of utterance plays a role: if the focus of attention is on a particular collection of kangaroos, for example, then “Q kangaroos” is likely to range over the individuals in that set. On the other hand, the utterance itself will help to establish the quantificational domain, inter alia through presuppositions triggered within the sentence. In this paper, we concentrate our attention on constructions like the following, in which “the square to which ... ” is the critical presupposition trigger:
Many theories predict that all instances of these schemata will give rise to the presupposition that every circle is connected to a square. We present an analysis which predicts that these sentences should generally be accepted in a context in which not all the circles are connected to a square, with one exception only: if a quantified sentence is of type (iii) and Q is non-intersective, then the sentence should be more likely to be rejected. Furthermore, we predict that manipulating the context so as to make the connected circles more or less salient should have an effect on statements with non-intersective quantifiers only. These predictions were tested in a series of experiments. 相似文献
