We studied the processing of two word strings in French made up of a determiner and a noun which contains a schwa (mute e). Depending on the noun, schwa deletion is present ("la tir'lire"), optional ("le ch(e)min") or absent ("la cornemuse"). In a production study, we show that schwa deletion, and the category of the noun, have a large impact on the duration of the strings. We take this into account in two perception studies, which use word repetition and lexical decision, and which show that words in which the schwa has been deleted usually take longer to recognize than words that retain the schwa, but that this depends also on the category of the word. We explain these results by examining the influence of orthography. Based on the model proposed by Grainger and Ferrand (1996), which integrates the written dimension, we suggest that two sources of information, phonological and orthographic, interact during spoken word recognition. 相似文献

This paper presents 4 studies which were conducted for the purpose of constructing and validating a new measure of people's motivation for environmental behaviors, namely the Motivation Toward the Environment Scale (MTES). The MTES consists of subscales that measure an individual's level of intrinsic, extrinsic, and a motivation for environmental behaviors. These subscales correspond to the different forms of motivation identified by Deci and Ryan in their self-determination theory (SDT, 1985, 1991). Results from the first study supported the factor structure of the scale and revealed a satisfactory level of internal consistency. Consistent with the SDT, the more self-determined forms of motivation were associated with more positive responses on the related variables. Implications for the manner in which the public could be encouraged to do environmental behaviors are discussed. 相似文献

The effects of delayed auditory feedback (DAF) on the performance of simple speech and keytapping tasks were compared. In the first experiment, each of the fourteen young adult subjects was asked to repeat the speech sound “b” in groups of three sounds. The subject heard his undelayed speech sounds through earphones. Under the delay condition, the speech sounds were delayed 244 millisec. before being returned to the subject's earphones. In the second experiment, each of the same subjects was asked to tap on a key in groups of three taps. The subjects heard an undelayed click through earphones each time they tapped on the key. Under the delay condition, the clicks were delayed 244 millisec. before being returned to the earphones. Graphic recordings were made of the time and intensity characteristics of tapping under both conditions.
The changes which occurred in speech and keytapping under DAF were qualitatively the same and consisted of increases in intensity and unit-to-unit time of both taps and speech sounds. When performing under DAF, the subjects also exhibited a tendency to repeat more sounds or to tap more times than had been requested. The percentage of change in intensity and time characteristics for speech and keytapping performances which occurred under DAF were not significantly different for the two motor systems. The amount of change in speech performance under DAF did not correlate significantly with the amount of change in keytapping performance. 相似文献

Singing is a cultural universal and an important part of modern society, yet many people fail to sing in tune. Many possible causes have been posited to explain poor singing abilities; foremost among these are poor perceptual ability, poor motor control, and sensorimotor mapping errors. To help discriminate between these causes of poor singing, we conducted 5 experiments testing musicians and nonmusicians in pitch matching and judgment tasks. Experiment 1 introduces a new instrument called a slider, on which participants can match pitches without using their voice. Pitch matching on the slider can be directly compared with vocal pitch matching, and results showed that both musicians and nonmusicians were more accurate using the slider than their voices to match target pitches, arguing against a perceptual explanation of singing deficits. Experiment 2 added a self-matching condition and showed that nonmusicians were better at matching their own voice than a synthesized voice timbre, but were still not as accurate as on the slider. This suggests a timbral translation type of mapping error. Experiments 3 and 4 demonstrated that singers do not improve over multiple sung responses, or with the aid of a visual representation of pitch. Experiment 5 showed that listeners were more accurate at perceiving the pitch of the synthesized tones than actual voice tones. The pattern of results across experiments demonstrates multiple possible causes of poor singing, and attributes most of the problem to poor motor control and timbral-translation errors, rather than a purely perceptual deficit, as other studies have suggested. 相似文献

Since the early days of physics, space has called for means to represent, experiment, and reason about it. Apart from physicists, the concept of space has intrigued also philosophers, mathematicians and, more recently, computer scientists. This longstanding interest has left us with a plethora of mathematical tools developed to represent and work with space. Here we take a special look at this evolution by considering the perspective of Logic. From the initial axiomatic efforts of Euclid, we revisit the major milestones in the logical representation of space and investigate current trends. In doing so, we do not only consider classical logic, but we indulge ourselves with modal logics. These present themselves naturally by providing simple axiomatizations of different geometries, topologies, space-time causality, and vector spaces. 相似文献

ObjectivesThis study aimed at confirming whether Motor Imagery (MI) enhances tennis serve performance, and determining whether a placebo condition could affect the beneficial effects of MI.DesignThis study used a 3 × 2 factorial design. Three groups of tennis players were compared in service performance outcomes before and after a training session.MethodsTwenty-two tennis players were assigned into three groups: a control (C) and two experimental groups subjected to a similar MI intervention, one group using their regular own racket (MI group) while the other used a placebo racket (P group).ResultsAnalyses of Covariance revealed no significant group difference when comparing serve velocity after training session, but MI training improved serve accuracy and regularity. Combining placebo racket with MI further resulted in greater serve accuracy score as compared to MI alone. Players' perception of their serve quality improved after MI, and this effect was reinforced in the P group.ConclusionThese findings revealed that MI may be useful to achieve peak performance, and that the implement placebo effect might be a factor in sport performance, hence promoting the beneficial effects of alternative methods to improve tennis serve performance. 相似文献

Both family decision making and consumer socialization studies have been focused largely on the influence of parents on children. However, because family communication is not unidirectional, studying teenagers' influence on their parents can provide a fuller understanding of consumers' resocialization processes. This study reports on 26 depth interviews conducted with teenagers and their mothers, designed to investigate how parental styles and frequency of communication between a teenager and parent affect parental ecological resocialization. Parental styles and the frequency of communication both have notable impacts on teenagers' influence on their mothers' pro‐environmental behaviors. Moreover, whereas bilateral strategies (bargaining and reasoning) are the most effective strategies used with warmer mothers, unilateral strategies (persuasion and nagging) are the least effective strategies used with cooler mothers.

Modern philosophy is characterised by various objections to the Aristotelian conception of happiness as the supreme good of human life. In this paper, I focus on the objections raised by two key thinkers of the modern period, namely Blaise Pascal and Friedrich Nietzsche. Both philosophers formulate important counter- arguments to the teleological claim that happiness is the highest good towards which all human beings naturally direct their efforts. Their target is not any specific definition of happiness as a particular kind of activity, or a particular kind of good. Instead, they express a more fundamental scepticism about the very possibility of happiness being the ultimate end of human life. As I show, Pascal's and Nietzsche's radical point is that, since reason alone can never answer for certain the question of whether or not happiness is the ultimate aim of human existence, philosophy should not concern itself with the question of happiness. The paper has three parts. I first sketch an outline of Pascal's sceptical argument with regard to happiness, and then present his positive definition of happiness, after which I do the same for Nietzsche. The third part is devoted to a critical assessment of their positions in light of an alternative argument developed by John Cottingham. 相似文献
