Two hundred seventy subjects were instructed to form an impression of a hypothetical target person described by several ambiguous behavioral descriptions. Immediately prior to this impression task, Ss memorized a list of priming (context) traits, some of which were applicable to encoding of the behavioral descriptions (and which were either positive or negative), and some of which were inapplicable (and either positive or negative). Behavioral descriptions pertained to traits that were either highly interrelated (homogeneous) or relatively unrelated (heterogeneous). Some Ss were told that they would be asked to recall the priming list after completing the impression task (expected recall), while the remaining Ss were not informed in advance of this recall task (unexpected recall).
