SUCROSE CONCENTRATION AS REINFORCEMENT FOR LEVER PRESSING BY MONKEYS

摘要: 3 rhesus monkeys were given various concentrations of sucrose for lever pressing on a variable interval schedule reinforcement. 7 studied at 2 levels food deprivation. The response rates accelerated rapidly with increasing concentrations, and then declined after reaching maximum, generally between 15 30% concentration. decline was attributed to satiation effect. higher level deprivation tended increase the rate all but extreme high low concentrations.
