The rise of this science has been so swift that other learning texts often overlook the fact that, like other mature sciences, the science of…

Several recent studies have explored what Michael (e.g., 1982) termed the "value-altering" effect and the "behavior-altering" effect of motivating operations. One aspect of the behavior-altering effect that has garnered no recent attention involves changes in stimulus control produced by motivating operations. To call attention to this aspect of…

Extinction and recovery of the discriminative stimulus effects of nicotine (0.3 mg/kg) was investigated with a devalued food reinforcer (rats sated). Sixteen rats were trained in a counterbalanced one manipulandum (nose-poke) drug discrimination procedure with the roles of nicotine and saline counterbalanced as S[superscript D] and S[superscript…

Investigates third- and fourth-grade children's verbal evaluations of syllables paired with different reward schedules (full, partial, or none) for "pleasantness" and "curiosity." (Author/ED)

It was the purpose of this study to ascertain whether the culturally disadvantaged child, who appeared to adhere to the principle of immediate gratification, had learned, as a function of his participation in Head Start, a more future-related orientation when compared to his non-Head Start counterparts. One hundred and eighty-seven 4- and…

Results indicated that a combination of primary and conditional reinforcers was most effective in developing a verbal conditioned reinforcer which effectively functioned as a self-reinforcer to facilitate new learning for 80 second grade Ss. (Author/WY)

This study tests the contention that a reinforcing agent's manner of administering rewards and punishments is construed by his associates as revealing his margin of freedom, and that associates are more attentive to cues concerning a reinforcing agent's dispositional qualities, and more inclined to ingratiate themselves to him, when he employes…
