Final answer:
The answer to the question is need fulfillment, which is not a distinct stage in Reiss's wheel theory of love but an outcome of the stages working together.
Step-by-step explanation:
The process that is NOT a part of Reiss's wheel-theory of love is D. need fulfillment. Reiss's wheel theory involves four stages that repeat cyclically: rapport, self-revelation, mutual dependency, and personality need fulfillment, which together nurture a love relationship. However, our focus on reciprocity, which is the mutual exchange in relationships, relates not to one standalone process in Reiss's model but rather to the overall dynamic nature of how relationships evolve through these stages.
In the context of Reiss's wheel theory, self-revelation is the process of sharing personal information that fosters intimacy. It is characterized by the reciprocal sharing of thoughts, feelings, and experiences, which enhances the bond between individuals. Attraction is also a fundamental component, contributing to the initial connection between people that can eventually lead to love.
