Twenty five years is both a very long time and a very short time. The OPS has seen many innovations— in technique as well as technology. At the same time, some things seem like they won't ever change. Our Society was conceived by Johnny Justice, Jr. (in the Spring of 1969 during a meeting in Sarasota, Florida); and Johnny is still a very active member! This paper is a reminiscence. Each of the ...

During the last twenty-five years, the contextual interference effect has been thoroughly studied. This review finds that the effect is relatively robust in basic research, but considerably weaker in applied settings. Motor learning scholars have urged practitioners to develop instructional strategies based upon the inferences of the contextual interference effect. The smaller effects seem to i...

Parker (1) has shown that the results of infectivity measurements with vaccinia virus may be interpreted as a Poisson distribution of single infective particles among aliquots of the virus obtained by dilution. Thus, if it may be assumed that there exists a quanti ty of virus invariably necessary and invariably sufficient to produce a lesion in the skin of the rabbit, the behavior on dilution r...

Turkey has initiated a number of projects to improve the quality of education and to provide students with knowledge and skills needed for the job market through the integration of information and communication technology (ICT) into education during the last twenty-five years. This paper is an overview of those initiatives of ICT in education in Turkey. It is argued that more attention is neede...

Students were exposed to a priming task in which subliminal representations of the goal of studying were directly paired (priming-positive group) or not (priming group) to positive words. A control group without subliminal prime of the goal was added. Just after the priming task, students performed an easy or a difficult learning task based on their coursework. Participants in the priming-posit...

In 2004, the Government of Timor-Leste introduced elections to villages (suku). Timor-Leste had only been formally independent since 20021, after some centuries of colonisation by Portugal (variable in the timing and degree of penetration), almost twenty-five years of more systematic occupation by Indonesia (1975–99), and two years of centralised transitional administration by the United Nation...

Abraham Flexner first toured the Yale University School of Medicine in preparation for his report of 1910, but it was just the beginning of his relationship with the school. While his review of Yale in his report was generally favorable, he mentioned several shortfalls that needed to be improved to make the school acceptable. Throughout the next twenty-five years, Flexner worked with Deans Geor...

thousand. Four years later there were about two hundred camps in existence, and five thousand boys were in the field. The number has increased steadily and rapidly in the last five years. Five years ago about ten thousand boys received the benefit of outdoor life during the summer months. During the past season, 1907, there were between four and five hundred summer camps, and about twenty-five ...
