Experimental studies on the head fake in basketball showed that participant’s responses in a pass direction identification task were delayed for incongruent compared to congruent directions of the players gaze and pass (so-called head fake effect). In these studies on the head fake effect, static pictures were presented and responses on the pass direction were given with a simple key press. The present study examines whether an increase in the response complexity affects the head fake effect and whether it can also be transferred to the presentation of dynamic stimuli. In experiment 1, participants were presented with static pictures of a basketball player who passes a ball to the left or to the right. The player’s gaze direction was either oriented in the direction of the intended pass or in the opposite direction (i.?e., a head fake). The participants were asked to respond as quickly as possible to the pass direction and to ignore the gaze direction. Participants gave responses by pressing a key (simple response) or by executing a quasirealistic defense movement (complex response). Response complexity was blocked. In experiment 2, videos replaced the static stimuli. The responses were only given with the complex, full body movement. Results show that the head fake effect is independent of response complexity and that it can also be found when presenting dynamic stimuli. 相似文献

This paper examines the media coverage of the murder of a young Muslim girl in Mississauga, Ontario in December 2007. We examine
how that coverage moved from concerns for a terrible family event to the use of the language of Samuel Huntington’s “Clash
of Civilizations.” We explore the nature of this exaggeration that occurs in times of threat and the “hardening” and eventual
clashing of identities that can follow. We interweave with these matters considerations of the pedagogical and familial consequences
of such identity-exaggeration under threat. We propose that the provisional, negotiated, and casual conviviality of identities
that precedes times of threat are cast into what Ivan Illich called “a zone of deep shadow.” We propose, also, that it is
this locale of an interdependent, co-determining conviviality of identities that can profitably be the locus of rich and intellectually
vital classroom conversations. 相似文献

ABSTRACT The study aims to explore attitudes of the United Arab Emirates University students towards the handicapped. A sample of 313 students, conventionally drawn, took the College Students' Attitude Scale towards the Handicapped. Statistical analysis revealed significant differences in favour of females vs males, single vs married, residents vs non‐residents, families with handicapped children, previous contact with handicapped and urban vs rural groups. Several recommendations are suggested at the end of the study. 相似文献

This study examines the practice of information ethics of the members of the mailing group of the Pakistan Library Automation Group, called PAKLAGPK who participate frequently in the discussions on a variety of LIS ethical issues. The research uses both qualitative and quantitative methods, including a survey questionnaire to measure subscribers' prior knowledge about certain issues in Information Ethics (IE). The research also uses the content analysis method to investigate the information communication behavior of the subscribers over this mailing group. 相似文献

Computer graphics is widely used in several areas of science such as computer science education. The execution of hardware and software computer systems can be skillfully simulated using computer graphics. Such a simulation is very attractive in teaching at a university level. It is a way of visualization where students can see the unseen. In this article, the function of a simple computer is simulated. A simulator ASSEM is developed which is suitable as a teaching tool in computer system courses along with mnemonic and assembly language. The algorithm for implementing such a simulator is also presented. 相似文献

A kinetic approach to evaluate salinity effects on carbon mineralization in a plant residue-amended soil 总被引:3,自引:1,他引:2
The interaction of salinity stress and plant residue quality on C mineralization kinetics in soil is not well understood. A laboratory experiment was conducted to study the effects of salinity stress on C mineralization kinetics in a soil amended with alfalfa, wheat and corn residues. A factorial combination of two salinity levels (0.97 and 18.2 dS/m) and four levels of plant residues (control, alfalfa, wheat and corn) with three replications was performed. A first order kinetic model was used to describe the C mineralization and to calculate the potentially mineralizable C. The CO2-C evolved under non-saline condition, ranged from 814.6 to 4842.4 mg CO2-C/kg in control and alfalfa residue-amended soils, respectively. Salinization reduced the rates of CO2 evolution by 18.7%, 6.2% and 5.2% in alfalfa, wheat and corn residue-amended soils, respectively. Potentially mineralizable C (Co) was reduced significantly in salinized alfalfa residue-treated soils whereas, no significant difference was observed for control treatments as well as wheat and corn residue-treated soils. We concluded that the response pattern of C mineralization to salinity stress depended on the plant residue quality and duration of incubation. 相似文献

INTRODUCTION Blood-Pb levels are taken as representative of dose/exposure, as all clinical symptoms resulting from the toxic effects of Pb are manifested mainly in blood. Lead exposure of children correlates with de- creased IQ, symptoms of hyper kinesis or minima brain dysfunction, poor learning, or defects in specific neuromotor tasks (Landgrin et al., 1980). Large number of observations over the years has associated lead exposure with human diseases (McMichael and Johnson, 1982). Ca… 相似文献

While the English language boasts a century of research into its most frequently-used words, no such attempt has ever formally
been made in the Arab world. This pioneering study presents a list of 500 commonly-used words in the Arabic language based
on compilations of words gathered from a number of popular reading series in Lebanon, spanning grades K to 3. This list can
serve as a powerful tool for language teachers—who face several challenges posed by the inherent nature of Arabic in terms
of diglossia, orthography and morphology—and provide them with a handy list of words for their pupils. The study has its limitations
in terms of scope, breadth and the nature of the technology used for counting words. Nonetheless, it makes a number of recommendations
for the future, including the development of a readability formula based on this list, the expansion of the scope of this
word list and improvement to increase its technical accuracy. 相似文献
