“…A first step almost certainly would consist of the establishment of a series of empirical links such that the stimuli of A are manipulated in conjunction with a measurement of the responses of B, and vice versa. We have seen several examples of this kind of research with attempts at the linkage of work on attraction with the rather diverse areas of aggression (Baron, 1971;Hendrick & Taylor, 1971;Pigg & Geen, 1971;Sachs, 1972), sequential learning theory (Lamberth, 1971), Hull-Spence behavior theory (Lott, Aponte, Lott, & McGinley, 1969;Lott, Bright, Weinstein, & Lott, 1970;Lott, Lott, & Walsh, 1970), and even impression formation (Griffitt, Byrne, & Bond, 1971;Rosenblood, 1970;Singh & Byrne, 1971). Second, similarities in the findings across paradigms lead to unifying conceptualizations, and differences lead to efforts to devise explanations of the divergencies.…”
