Effects of Differential Instructions and Anxiety Level on Discrimination Learning

Seventy-seven nonconserver-conserver dyads and 53 nonconserver-nonconserver dyads were given a conservation of length task which encouraged conflicting judgments from the nonconserving dyad. Ss were boys and girls aged 4 through 8. Control tasks for social dominance/compliance were also administered. All sessions were videotaped. The nonconserver-nonconserver dyads did not tend to produce the correct answer by perspective coordination and showed little posttest gain. Nonconservers who had been paired with conservers showed posttest gain on length, mass, liquid, and number conservation problems. Being the winner of an interaction session was associated with opposing the partner's judgment and with producing justifications in conserver-nonconserver dyads, but only with social compliance in nonconserver-nonconserver dyads. Justifications in support of conservation judgments were invariably by logical principles but very rarely so in support of nonconservation judgments. The results are discussed in terms of the relative importance of cognitive conflict and transmission as crucial social experiences in cognitive development, and in terms of the possibility that nonconservers may lack the notion of objective correctness relative to conservers.
