Question 1 Short Answer
According to Byrne's reinforcement-affect model, why does attitudinal similarity increase attraction?
Think about your answer, then reveal below.
Model answer: Similar attitudes produce a feeling of validation and agreement, which is intrinsically rewarding. We associate the person delivering this reinforcement with positive affect and come to like them.
The key mechanism is cognitive validation: when someone agrees with your worldview, your attitudes feel confirmed as reasonable. The positive affect generated by this confirmation transfers to your evaluation of the person who expressed agreement.
Question 2 Short Answer
A study finds that people overestimate how similar they are to their romantic partners. What does this suggest about the similarity-attraction link?
Think about your answer, then reveal below.
Model answer: It suggests that perceived similarity — not just objective similarity — drives attraction and relationship satisfaction. The belief that your partner understands and shares your worldview may be as important as whether they actually do.
This finding shows that the psychological mechanism (feeling validated and understood) can operate even when the objective similarity is less than perceived. It also raises questions about how relationships change when people discover they are less similar than they thought.
