The paper focusses on the different kinds of aggression, specifics of aggression in children in their developmental stages, developmental trajectories of aggression, gender differences in aggression, determinants of aggression, theories of origin of gender differences, and international comparisons of aggression. The objective of the research was to examine specifics of aggression in a Czech sample group, compare Czech results with the results of the other countries (Greece, France, Germany, Italy, Turkey, China, India, Venezuela, Colombia, Mexico and Peru), and examine the effects of age, gender, sibling birth order, and parenting styles on aggression.
The mean of factors of aggression in the Czech sample was among the lowest of the countries mentioned above. We didn't find any significant difference among groups based on age, gender, sibling birth order or divorce of parents.
The main finding was the discovery of eight significant correlations in boys and four significant correlations in girls between FTT's factors of aggression and their parents' upbringing styles.
