According to some recent studies, it appears that the IQ of children is increasing. Some experts feel that this increase is that corporal punishment is declining in most countries. One study has been conducted through a survey of 17,000 university students from 32 different countries.
The survey shows that the higher the percentage of use of corporal punishment by parents, the lower the IQ. Another study was conducted in the United States reviewed the data of IQ of 806 children aged between two and four years, and 704 children aged between five to nine years.
When testing again to see IQ 4 years later, research managers were able to see how children in the younger group that they were not punished , they stuck up five points (average), that children which they had been whipped. In the group of older children, those who had suffered some form of physical violence they had lost 2.8 points.
According to the study director, Dr. Straus, the more strokes the child receives, the slower the development of the child's mental capacity. In conclusion, the study explains that if the aim is to teach the child through his cheeks, the method chosen is not correct. If using other methods to discipline the child, then it will develop their cognitive abilities.
