EFFECTS OF TRANSMITTER TUNING ON ATTITUDE-CHANGE PERSISTENCE - AN EXAMINATION OF ALTERNATIVE EXPLANATIONS

Lassiter, Pezzo, and Apple (this issue) replicated the effect of transmitter tuning on attitude change persistence (Boninger, Brock, Cook, Gruder, & Romer, 1990) and included an additional condition as the basis for an alternative explanation. Although their independent replication is an important contribution that provides significant empirical corroboration, a superficial rendering of the interrupted-task literature (Zeigarnik, 1927/1938) and ambiguity in the operationalization of the additional condition appear to weaken their proposed interruption-perseveration explanation. We also summarize ancillary data from our earlier work (Boninger et al., 1990) that shed further doubt on this alternative explanation.
