Male goalkeepers of intermediate skill level attempted to stop penalty kicks executed with the instep and inside foot, in
situ. A mobile eye tracker and an external camera were used to collect the gaze and motor behaviors of the goalkeepers, as
well as the penalty takers’ motor behaviors and flight of the ball. Percent saves was greater during instep (28%) than inside
foot kicks (12%), but we detected few differences in fixation frequency, location, duration, or transitions that could be
attributed to the type of kick used. Fixation transitions (or the frequency of gaze shifts between locations) were significantly
higher on goals than on saves. During the final phase of the kicking action, the quiet eye was located on the visual pivot
and was longer during saves than goals. Furthermore, when the final fixation on the ball exceeded approximately 1,100 ms,
then the likelihood of goals increased. The results are discussed in light of past studies in goaltending and the dual demands
of motor tasks that require information be fixated both early and late at spatial locations that exceed the limits of focal
vision. 相似文献

This paper reports the results of two experiments. In the first, voice-key naming times were collected and in the second, keypress naming times were collected for 250 of the Snodgrass and Vanderwart (1980) pictures. The resulting naming times and correct naming rates were well predicted in multiple regression analyses by one or another measure of codability (name or concept agreement) and by age-of-acquisition ratings collected specifically for this study. Voice-key responses appeared to be somewhat more sensitive indicators of naming difficulty, although keypress responses did remarkably well. The Appendix presents the age-of-acquisition ratings, the trimmed vocal and keypress naming times, and the correct naming rates from the two experiments for the 250 pictures. 相似文献

Previous findings indicate that bilingual Catalan/Spanish‐learning infants attend more to the highly salient audiovisual redundancy cues normally available in a talker's mouth than do monolingual infants. Presumably, greater attention to such cues renders the challenge of learning two languages easier. Spanish and Catalan are, however, rhythmically and phonologically close languages. This raises the possibility that bilinguals only rely on redundant audiovisual cues when their languages are close. To test this possibility, we exposed 15‐month‐old and 4‐ to 6‐year‐old close‐language bilinguals (Spanish/Catalan) and distant‐language bilinguals (Spanish/”other”) to videos of a talker uttering Spanish or Catalan (native) and English (non‐native) monologues and recorded eye‐gaze to the talker's eyes and mouth. At both ages, the close‐language bilinguals attended more to the talker's mouth than the distant‐language bilinguals. This indicates that language proximity modulates selective attention to a talker's mouth during early childhood and suggests that reliance on the greater salience of audiovisual speech cues depends on the difficulty of the speech‐processing task. 相似文献

Interventions including social scaffolding and metacognitive strategies have been used in educational settings to promote cognition. In addition, increasing evidence shows that computerized process‐based training enhances cognitive skills. However, no prior studies have examined the effect of combining these two training strategies. The goal of this study was to test the combined effect of metacognitive scaffolding and computer‐based training of executive attention in a sample of typically developing preschoolers at the cognitive and brain levels. Compared to children in the regular training protocol and an untrained active control group, children in the metacognitive group showed larger gains on intelligence and significant increases on an electrophysiological index associated with conflict processing. Moreover, changes in the conflict‐related brain activity predicted gains in intelligence in the metacognitive scaffolding group. These results suggest that metacognitive scaffolding boosts the influence of process‐based training on cognitive efficiency and brain plasticity related to executive attention. 相似文献

Ask most any cognitive scientist working today if a digital computational system could develop aesthetic sensibility and you will likely receive the optimistic reply that this remains an open empirical question. However, I attempt to show, while drawing upon the later Wittgenstein, that the correct answer is in fact available. And it is a negative a priori. It would seem, for example, that recent computational successes in textual attribution, most notably those of Donald Foster (famed finder of Ted Kazinski a.k.a. “the Unibomber”) speak favorably of the digital model's capacity to overcome the “aspect blindness” handicap in this domain. I argue however that such results are only achievable when rigid input‐to‐output parameters are given, and that this element is precisely what is absent in standard examples of aesthetic judgment. I thus conclude that while the connectionist model anticipated by Turing may provide the best approach for the AI project, its capacity for meeting its own sufficiency requirements is necessarily crippled by its inability to share in what can be generally referred to as the collective engagements of human solidarity. 相似文献

Self-determination theory (Deci & Ryan, 2000, Intrinsic motivation and self-determination in human behaviour. New York: Plenum Publishing) highlights the impact autonomy supportive environments can have on exercise motivation and positive health outcomes. Yet little is known about whether differential effects occur as a function of which significant other is providing this support. Further, no research has examined the relationship between motivation and the social environment with participants' mental health and intentions to be physically active before entering an exercise intervention. Study participants were 347 British adults who were about to start an exercise referral scheme. Regression analyses revealed that the effects of autonomy support on mental health and physical activity intentions differed as a function of who provided the support (offspring, partner or physician), with the offspring having the weakest effects. A structural model was supported, indicating that autonomy support and more autonomous regulations led to more positive mental health outcomes and stronger intentions to be physically active. Knowledge of the social environmental and personal motivation of those about to commence an exercise programme can provide important insights for professionals supporting such efforts. 相似文献

We investigated relations between maternal control and girls’and boys’ concern for others. Fifty-six pairs of children were
separately interviewed, using a newly developed measure of empathy. While mothers completed a parenting inventory, we videotaped
children as one child attempted to convince a friend to make greeting cards for hospitalized children. High maternal control
was associated with lower empathy and less interpersonally sensitive verbal persuasion, but only in girls. 相似文献

The empirical finding that school-aged children could suffer clinical depression refuted the widely held assumption that this age group would be too developmentally immature to experience depressive symptoms. Currently childhood depression is a well-recognized and widely treated clinical disorder. Following more recent developmental findings emphasizing the emotional sophistication of very young children, scientific studies have demonstrated that depression can arise early in life, during the preschool period of development. Preschool depression is characterized by typical symptoms of depression such as anhedonia; changes in sleep, appetite, and activity level; and excessive guilt. Further, longitudinal continuity of preschool depression into school age has been established, suggesting that preschool depression is an early manifestation of the later childhood disorder. Based on the known efficacy of early developmental intervention in a number of domains and disorders related to the greater neuroplasticity of the brain earlier rather than later in childhood, it is important to identify depression at the earliest possible point. Early intervention strategies for preschool depression that focus on enhancing emotional development are currently being tested. 相似文献
