Final answer:
The Walster (1965) study concluded that individuals are likely to develop a preference for those who show an interest in them, particularly when they have low self-esteem.
Step-by-step explanation:
The conclusion drawn from the Walster (1965) study is that we tend to like those who like us, especially when our self-esteem is low. This finding supports the notion that our attraction to others is not solely based on their attributes or our self-perception, but also significantly influenced by the reciprocal feelings they express towards us. This has implications for understanding the dynamics of interpersonal relationships and the role of self-esteem in social interactions.
