Commitment, enjoyment and motivation in young soccer competitive players

Building upon Deci's and Ryan (1985) Self-determination theory as well as the sportive behavioral correlates of the model of Commitment (Scanlan et al., 1976), this study tries to establish the relationship between motivation and commitment in youth sport. For this purpose 454 young competitive soccer players answered the Sport Motivation Scale (SMS) and the Sport Commitment Questionnaire (SCQ) during the regular season. The SMS measures the three dimensions of the Motivational continuum (the Amotivation, the Extrinsic Motivation and the Intrinsic Motivation). The SCQ measures the Sportive Commitment and its composing factors such as the Enjoyment, the Alternatives to the sport, and the Social Pressure. Our findings provided a clear pattern of the influence of motivation in sport enjoyment and commitment, outlining the positive contribution of intrinsic and extrinsic motivation to enjoyment and commitment. Amotivation, contributes positively to alternatives to sport and negatively to enjoyment and commitment, It should be noted that extrinsic motivation has a higher contribution to enjoyment whereas intrinsic motivation has a higher contribution to commitment.     

Exploring the role of national culture on knowledge practices: a comparison between Spain and the UK

In the context of a competitive knowledge-based economy, the knowledge provided by a firm's founders is one of the most important measures of success. This paper aims to identify the role of national culture on a founder's knowledge practices in a modern organisation. Using data collected from 258 Small to Medium sized Enterprises (SME(S)) in the Spanish and UK telecommunication industries (130 from Spain and 128 from the UK), we propose three knowledge management practices to be analysed; namely transfer, transformation and open-mindedness. This paper provides evidence that while Spanish SME(S) are more positively associated with higher levels of transfer and transformation of knowledge, UK SME(S) are more positively associated with higher levels of open-mindedness. Hence, this study serves as an important contribution to the small amount of literature currently available in this field by examining different practices that can be explained by the cultural characteristics of both countries.     

自然分娩与剖宫产的比较研究

剖宫产不是一种分娩方式,而是解决难产的手段.日益增高的剖宫产率成为人们关注的热点话题,自然分娩和剖宫产对母婴的健康和卫生资源的影响,有很多的研究和争议,对于没有医学指征要求剖宫产目前倾向于在知情同意的情况下尊重患者的自主权和选择权,但控制剖宫产率在一个理性的范围之内,是一个系统工程,值得全社会的关注.

Treatment dynamics in sensorimotor disorders: the contribution of electrophysiology]

In the field of sensorimotor activities, progresses achieved over the last fifty years have been largely driven by the Reaction Time (RT) paradigm. Information processing models are set in the context of a global breakdown of sensorimotor activities in multiple concatenated stages, each aggregated in many fundamental operations that are functionally linked. If there is a consensus today about this breakdown, the way stages organize themselves in time however is still much debated. According to one hypothesis, there is no temporal overlap between each stages: the process occurs sequentially. According to another theory, the stages overlap over in time: the process occurs in a parallel manner. A behavioral analysis does not allow to determine between these two hypothesis because the RT represents the final product of the whole sensorimotor pathway, while the temporal organization of the processing of information depends on the nature of the transfer between individual stages. An all-or-nothing information transfer, also called discrete, leads to a sequential organization, while a progressive or continuous transfer brings about a parallel organization. Moreover, contrary to a preconceived notion, data obtained from classical neurophysiology are compatible with both a sequential organization and a parallel organization. Particularly, the great number of connections between the different elements of the nervous system has often seemed difficult to conciliate with a sequential organization. In fact, this argument is inadmissible because it stems from confusion between a temporal organization and an anatomical organization of the processing of information. More generally, our knowledge of the functional anatomy of sensorimotor activities imposes but few constraints on the temporal organization patterns of the processing of information. The lack of interest for the neurophysiological argument seems essentially due to the fact that theses arguments rest on research which is not aimed at the temporal organization of the sensorimotor information processing. Recently, approaches that integrate concepts and methods used in experimental psychology and neurosciences have contributed to putting in perspective the organization of information processing. Electromyography, EEG, reflexology and neuronal recording techniques have been used in the context of two inference logics. The first logic, that we call "factual", is based on the study of functional relations between RT and certain neuronal events. The second logic, that we call "chronometric", is based on the study of the relationships between RT and intervals resulting from the breakdown of the RT in relation to certain neuronal events. Generally speaking, most studies suggest that in tasks where the stimulus is composed of numerous attributes, information processing operates in parallel. On the other hand, when the stimulus is made up of a single attribute, information processing could be operating in a sequential manner. One weakness of this electrophysiological approach is that it has so far only examined relationships between physiological indicators and means RT. We propose here to offset these weaknesses by examining functional relationships between RT distribution variances and certain neuronal events linked to information processing.     

Physiological evidence for response inhibition in choice reaction time tasks

Inhibition is a widely used notion proposed to account for data obtained in choice reaction time (RT) tasks. However, this concept is weakly supported by empirical facts. In this paper, we review a series of experiments using Hoffman reflex, transcranial magnetic stimulation and electroencephalography to study inhibition in choice RT tasks. We provide empirical support for the idea that inhibition does occur during choice RT, and the implications of those findings for various classes of choice RT models are discussed.     

Cross-cultural differences in female university students' attitudes toward homosexuals: a preliminary study

62 Caucasian, 61 Hispanic, and 44 Asian female undergraduates completed the Index of Homophobia by Hudson and Ricketts, seven items from the Attitudes Toward Lesbians and Gay Men Scale by Herek, and three questions on Affectional Orientation toward homosexuals from D'Augelli and Rose. Overall, familiarity with homosexuals as measured by self-reported number of homosexual friends correlated negatively with scores on the homophobia measures, but there were no significant differences among the groups' reported number of homosexual friends. Asian students scored significantly higher on the homophobia measures than Caucasian students. Both Asian and Hispanic students endorsed the statement significantly more often than Caucasian students that the university would be better if only heterosexuals attended. No significant differences in scores were found regarding attitudes toward lesbians versus gay men.     

Lightness depends on immediately prior experience

The lightness hangover illusion is an unusually robust, long-lasting, prior-experience-based lightness effect. The effect occurs in the Mondrian world, a miniature chamber with interior walls covered with dark gray to black patches. The lightest patch in this scene, physically dark gray, looks white. When real whites and light grays are added to the scene, all the patches darken, but at an unusually slow rate. For several seconds, the white patches look self-luminous and the other patches continue to look very light. The luminosity fades and the other patches darken only after 2 min. We tested three possible explanations for this illusion: retinal adaptation, lightness persistence, and anchor persistence. The results clearly support anchor persistence, which is caused by the presence of steady patches, surfaces that retain their luminance values across scenes. The data also show that the size of the illusion varies directly with the number of these steady patches.     

Personality and aesthetic preference in Spain and England: two studies relating sensation seeking and openness to experience to liking for paintings and music

In two studies, one employing Spanish students and the other English students, questionnaire measures of Sensation Seeking and Openness to Experience were correlated with liking for major music types, several short music excerpts, and eight categories of painting (presented as slides). Inter‐correlations between music preference measures, painting preference, and personality are reported. In both samples, the Sensation Seeking Scale (Form V) and, particularly, the Experience Seeking sub‐scale were associated with a factor contrasting liking for ‘hard rock’ music and ‘violent–abstract’ art with liking for ‘neutral–realistic’ art and ‘easy listening’ music. Several substantial relationships between aesthetics measures and Openness to Experience (from the NEO‐PI‐R) were also found, though mostly in the English sample. The results reinforce the view that personality dimensions such as Sensation Seeking and Openness are important influences on aesthetic judgment. Copyright © 2000 John Wiley & Sons, Ltd.
