Abstract
"This study investigated the operant conditioning of a class of verbal behavior as a function of manifest anxiety and of two types of social approval in grade school children. Anxiety levels were inferred from the Children's Manifest Anxiety Scale. Social reinforcers consisted of a 'head nod' and the verbalization 'good.' Acquisition of a verbal conditioned response was obtained in both reinforcement groups with the verbal reinforcer being significantly better than physical movement. Anxiety effects were not demonstrable." (PsycINFO Database Record (c) 2006 APA, all rights reserved)
