Eighteen objective devices previously validated as interest measures, and chosen as markers to test the hypothesis that there are seven disignatable motivation components, were administered to 135 undergraduates for each of two attitude-interests wanting to participate in sports and wanting to get better grades. Both areas pointed to 8 or 9 factors and eight were taken and rotated to maximum simple structure on most factors. The agreement of patterns at these unique independent resolutions was tested by both congruence coefficients, r's, and salient variable similarity indices, s's which showed (a) significant agreement of the majority of factors with the hypotheses expressing, in patterns, the previous researches, (b) significant agreement of sports and grades, indication independence of motivation components with respect to area of interest. However, three factors showed some weakness of match in one leg of three cornered comparison of grades, sports and pioneer experiments. An alternative theory is presented here according to which four of the factors are considered to align themselves with dynamic calculus concepts represented in the specification equation for an intereset from ergs, sentiments, the arousal adjunct to an erg, and the activation expression of a sentiment.
