Answer:
I. Viewing many television programs that associate successful males with football
III. Operant conditioning
IV. Gender schemata
Explanation:
As we can see in the question above, the boy contracted a very wrong custom of associating virility with his ability and taste for playing football. According to the boy, he is only manly and manly enough boys who like and know how to play football.
This thought (which is extremely wrong) occurs with the influence of some things. The first is the frequency with which this boy watches many television programs that show men, soccer players with a successful and well-established career.
The second influence is the result of operant conditioning, which is a psychological concept characterized by a form of learning that allows a person to associate a situation with a punishment. In this case, the boy associates the lack of skill and the lack of interest in football with words that cause embarrassment as punishment. For this reason, he calls his colleagues who don't like football "sissy".
The third influence occurs through gender schemes, which is a term used to describe the separation of things, activities and behavior as feminine and masculine, in addition to determining that only women can do what is considered feminine and only men can do what it's male. The boy associates football with masculinity and those who do not like or have no interest in football are feminine, effeminate and not men.
