Student subjects were presented with results of an opinion survey dealing with political, religious and social issues. Their task was to indicate the likelihood of the survey having been conducted in each of a series of countries listed, including Britain. There was a high degree of consensus on the type of nation considered likely. Perceived similarity to Britain of the countries was assessed, and the relative saliency of various criteria determined. Content analysis of verbal reports indicated that the same judgments were made on a variety of different grounds, and yielded insights into the modes of impression formation. Characteristics of the Ss’ ‘cognitive maps’ of Western European and Communist countries are discussed.
