John B. Watson remembered: an interview with James B. Watson

Little is known about the personal life of John B. Watson, and this interview aims at capturing the personality of the founder of American behaviorism through the eyes of his son, James B. Watson. Today, psychologists and other social scientists increasingly realize that there is an intimate link between the biography of a psychologist and the kind of psychology he or she founds. Thus biographical information about a founding psychologist can help researchers make explicit this essential link.     

In Hall's shadow: Edmund Clark Sanford (1859-1924)

Edmund C. Sanford of Clark University had earned a reputation by the end of the nineteenth century as a leading American psychologist. He had written the first training manual for experimental psychology and created numerous pieces of laboratory apparatus. He was also editor of the American Journal of Psychology and a charter member of the American Psychological Association. Although his peers elected him to the presidency of the APA in 1902, his standing had already begun to decline. Sanford's impact on early American experimental psychology is documented and the reasons for his reduced status as American psychology grew in the early years of the new century are explored.     

The choice of constraints in correspondence analysis

A discussion of alternative constraint systems has been lacking in the literature on correspondence analysis and related techniques. This paper reiterates earlier results that an explicit choice of constraints has to be made which can have important effects on the resulting scores. The paper also presents new results on dealing with missing data and probabilistic category assignment.I am most grateful to the following for their helpful comments.
