Ak. Bayhinitz et al., COOPERATIVE GAMES - A WAY TO MODIFY AGGRESSIVE AND COOPERATIVE BEHAVIORS IN YOUNG-CHILDREN, Journal of applied behavior analysis, 27(3), 1994, pp. 435-446
We investigated the effects of competitive and cooperative games on ag
gressive and cooperative behaviors of 70 children (4 to 5 years old) f
rom four classes in three preschools. The experimental design included
both multiple baseline and reversal components. Behaviors were measur
ed during game conditions and in subsequent free-play periods. Results
showed that cooperative behavior increased and aggression decreased d
uring cooperative games; conversely, competitive games were followed b
y increases in aggressive behavior and decreases in cooperative behavi
or. Similar effects were also found during free-play periods.
