| Abstract: | This paper examines the question of informant accuracy in reporting patterns of communication in face-to-face groups. We are attempting to establish the extent to which it is possible to predict individual differences in accuracy from the patterns of recall among informants. We use data from a series of studies by Bernard, Killworth, and Sailer (Killworth and Bernard, 1976, Killworth and Bernard, 1979Bernard and Killworth 1977;Bernard et al., 1980, Bernard et al., 1982) in which they collected observed behavior interaction frequencies and subsequently asked informants to recall and rate the degree of previous communication. In this paper we attempt to predict the accuracy of recall, i.e. how well each individual's ranking corresponds to the overall observed interactions for the group as a whole, by looking solely at the recall ranking. Using this method, we are able to account for a major share of the variance in accuracy among the subjects. We outline a theory and method for predicting accuracy based upon recall data that may be generalized to a variety of situations beyond social interaction data. |
