This report is on one aspect of a study that is trying to provide a reference basis for different researchers in their combined efforts to conceptualize and develop a theory and structure of human abilities and temperament. Specifically, the study is directed toward the identification of tests and other instruments that can serve as markers for well established factors. It is the noncognitive area of the study to which the present report is addressed. There is sufficient concensus on many of the temperament factors to make a review and interpretation of recent factor analyses leading to such factors worthwhile. Separately presented in this report are 28 factors that can be called "established," in that they have been found at least three times in reports emanating from at least two different laboratories. It suggests and describes one to five subscales that might be used as marker variables. This literature review takes the form of a discussion of the various analyses in which the factor seems to have appeared and the extent to which the listed subscales measure it. The subscales of items, which this project will ultimately recommend as factor markers, will depend on the results of our own tryouts of the item categories listed in this report coupled with the findings reported in the literature.
