The orbitofrontal cortex (OBFc) has been suggested to code the motivational value of environmental stimuli and to use this information for the flexible guidance of goal-directed behavior.

Two studies were conducted to clarify the role of different minimum performance standards for contingent tangible reinforcement or self-dispensed evaluative reinforcement (in the absence of tangible rewards) in determining the rate and accuracy of learning. Preschool children were presented with a discrimination learning task. Their performance…
