Three groups of Ss learn a consistent pattern of responses: LR, LL, or LLR. After a random schedule of trials a LR pattern is introduced for all groups. Experience with LR or LL but not with LLR leads to faster final learning of LR. "The results are explained in terms of previous experience making the final pattern more discriminable, with discriminability strongly influenced by Ss learning to adopt a consistent mode of response against which an event pattern stands out clearly rather than being masked by response variability." 18 references.
