PSYCHOLOGICAL PREDICTORS OF INDIVIDUAL DE VELOPMENT

Individual characteristics were twice (at an age of 2,3 years and at a n age of 7,8 years) diagnosed in 36 twin pairs. For the former two, Ba ily scales (intellectual development and behavior evaluation) were use d; for the latter - Stanford - Binet test (intellect), Torrance test ( creativity), Liders test (school readiness). Mother's characteristics were evaluated too (intellect, extraversion, neuroticism). Children's weight at birth was registered. Predictors were found by means of mult iple regression analysis. A predictor's value was the highest when it was connected to the same variable as the response or when it was of a complex nature. It can be assumed that predictors are connected to th e responses by common genetic factors.
