However, most of the time, verbal encouragement/reinforcement was given several times during the task, and the encouragement used was often a personal trait (“You’re good, “you’re clever”, etc.).

The instructor told half of the children “You are a clever boy/girl. You can succeed” (verbal encouragement condition), while she said nothing to the other half of the children (control condition). It was reported that 77% of the children responded correctly in the verbal encouragement condition while only 30% responded correctly in the control condition. In the second study, 8–9 year-old children were asked to do an alphabetical order task using the names of 7 well-known fruits printed on a paper.

Results showed that more children succeeded in the verbal encouragement condition (82%) than in the control condition (47%). The importance of verbal reinforcement for teachers is discussed
