A set of practical behavior change techniques for improving young children's classroom behavior are briefly discussed. Techniques are classified and discussed under two general categories: those that reduce frequency of behaviors ("sticks") and those that increase their frequency ("carrots"). Included under "sticks" are techniques such as ignoring the child's target behavior, time out (removing the child for a short time from all sources of attention), overcorrection and undoing (requiring the child to "overcorrect" his misbehavior in his own free time), and taking away privileges (for example, preventing the misbehaving child from participating in a favorite activity or playing with a preferred toy). Classified with the "carrots" are techniques such as giving attention and praising a positive behavior, shaping a behavior (breaking every target behavior into smaller components or steps, which are then reinforced), and contingencies and rules (having the child first demonstrate the target behavior before earning the privilege). To further illustrate how some of these "sticks" and "carrots" may be applied, seven typical and simplified cases are presented. (MP)
