Final answer:
The following true about the theories of attribution is A). The above average effect stems from the fact that we attribute all our behaviours as being situational.
Step-by-step explanation:
The fundamental attribution error is the tendency to overemphasize internal factors and underestimate situational factors when explaining the behavior of others. It occurs when we attribute someone's behavior to their personal characteristics, such as their personality traits or disposition, rather than considering the influence of the situation they are in.
One example of the fundamental attribution error is the Quizmaster study, where participants rated the intelligence of questioners higher than their own despite the fact that the questioners had an advantage due to their role. This error is more prevalent in individualistic cultures. On the other hand, the self-serving bias is the tendency to attribute our successes to personal characteristics and our failures to external factors. It serves to protect self-esteem and can vary across cultures. The correct answer is A). The above average effect stems from the fact that we attribute all our behaviours as being situational.
