[1] Two recent studies have found that punishment is not the best way to influence behavior. One showed that adults are much more cooperative if they work in a system based on rewards.
[2] They had about two hundred college students play a version of the game, which is based on the tension between the interests of an individual and a group. The students played in groups of four. Each player could win points for the group, so they would all gain equally. But each player could also reward or punish each of the other three players, at a cost to the punisher. The most successful behavior proved to be cooperation. The groups that rewarded it the most earned about twice as much in the game as the groups that rewarded it the least. And the more a group punished itself, . The group with the most punishment earned twenty-five percent less than the group with the least punishment.
[3] The other study involved children. It was presented last month in California at a conference on violence and abuse. Researchers used intelligence tests given to two groups. More than eight hundred children were ages two to four the first time they were tested. More than seven hundred children were ages five to nine. The two groups were retested four years later, and the study compared the results with the first test. Both groups contained children whose parents used physical punishmen
t and children whose parents did not. The study says the IQs — or intelligence quotients — of the younger children who were not spanked (打屁股) were five points higher than those who were. In the older group, the difference was almost three points.
[4] Murray Strauss from the University of New Hampshire worked with Mallie Paschall from the Pacific Institute for Research and Evaluation says the more they are spanked, the slower their mental development is. He also looked at average IQs in other nations and found them lower where spanking was more common.
