Important notice!!!!

The version that has been published contains four typographical errors.

Please accept our sincere apologies for the inconvenience.

Here are the corrections

1/ On page 857, Table 2: the correlation coefficient of EXP and BEH
is correctly printed as 0.385 but it should be shown to be significant, i.e. 0.385**

2/ On page 858, Table 3, Equation 4: the b of SVO should read 2.042 and not -2.042

3/ On page 858, the sentence

“Indeed, the coefficient associated with the PRIME * SVO interaction has been reduced from 2.508 (in Equation 4) to 0.041 (in Equation 6).”

should read

“Indeed, the coefficient associated with the PRIME * SVO interaction has been reduced from 2.574 (in Equation 4) to 0.041 (in Equation 6).”

4/ On page 860, bottom of second column: the first equation should read Ho: b₄₃ - b ₆₃ = 0
