The author examines the influence of grandparents (the second preceeding generation) on individal differences in creativity and intelligence. Those children, in whose upbringing granmothers had a bigger part, have a higher level of creativity. The author distinguishes between two different approaches to upbringing: one by parents and the other by grandparents. Grandmothers’ positive impact on creativity can be explained by the following factors: lessening prohibitions and demands from the adults; allowing children more emotional self-expression; encouraging positive self-esteem in the child. Using the method of multiple regresion analysis, the author analyses the impact of each factor on children’s abilities.
