Ever since the technique widely known as the semantic differential was pioneered by Charles Osgood, it has been widely applied in most of the social sciences, as well as in a variety of other fields. While the broadest applications of the technique, including much of Osgood's own work, are in the areas of experimental and social psychology, variants of the semantic differential are widely scattered through research in such diverse fields as linguistics, anthropology, and education, not to mention such non-academic fields as journalism and marketing. The attempt by a number of political scientists, particularly in Britain and in Canada, to adapt this technique to the study of political party images represents one of these variants.

7 The data utilized in this paper were made available by the Inter-University Consortium for Political Research, the European Consortium for Political Research and the University of Strathclyde, and were originally collected by David Butler and Donald Stokes. Neither the original collectors of the data nor any of the institutions bear any responsibility for the analysis or interpretation of the data contained herein.
8 All factor analyses reported here were principal component analyses with orthogonal rotation. Kaiser's criterion (eigenvalues > 1·0) was employed in retaining factors for rotation. In each of the tables factor loadings > ·40 are printed bold for emphasis. The interpretation of the factors is of course that of the author alone and, in some instances, alternative interpretations are quite conceivable. Where possible, an ‘Osgood’ interpretation is given in brackets to test the conformity of the structure to the E-P-A model. An asterisk following this interpretation is intended to indicate that its applicability is at best marginal.
9 All of the factor analyses discussed here were also conducted with the dummy variables excluded. In general, the inclusion of the partisan self-image dummy variables did not change the factor structure, but it did provide the opportunity of examining the loading of partisanship on the dominant E factor.
10 An interesting and useful comparison is afforded by the Canadian data, on which an analysis parallel to that reported here was conducted. The most striking characteristic is the dominance of the E (or affect) component, even more marked than in the British case. This holds without exception for all three parties. For the two major parties (Liberal and Conservative), the second factor is an activity factor, suggestive of the Osgood ‘A’ component. For the New Democratic party, a somewhat residual class/ideology factor emerges.
11 The inclusion of the slow/fast word pair in the Canadian study doubtless accounts for the emergence of the A factor in that analysis. But the inclusion of pairs such as powerful/weak and strong-minded/weak-minded did not similarly produce a potency [P] factor as might have been expected. Eleven of the word pairs employed in the 1965 Canadian study were identical to those used in the British studies, or closely comparable. See Meisel, , Working Papers, pp. 63–119.Google Scholar
12 The Osiris ‘Fcomp’ program provides a means of statistically testing the comparability of two independent factor structures. In the analysis undertaken here, an intraclass correlation coefficient of ·95 is obtained between the 1966 and 1970 panels for the Labour party structure, and a coefficient of ·87 between the Labour and Conservative structures in 1966. Other combinations were not tested, but it is clear that the comparability of the Liberal party structure with that of the Labour and Conservative parties would be low. There is no reason however to believe that it would not be as stable over time, and indeed the research of Osgood and others should lead us to expect such stability.
