 Despite CTW 's concern that the show would widen the gap between well @-@ to @-@ do children and their less wealthy peers , there was no evidence that this occurred ; gains made by disadvantaged children were as great as those by advantaged children . The show 's positive general effects , as cited by ETS , occurred across all childhood demographics ( gender , age , geographic location and socioeconomic status ) . Studies conducted by ETS seemed to suggest that the program had " a significant impact on children 's social behavior " , although the evidence was not as strong as it was for cognitive effects ; fewer studies exist of social behavior .
