Final answer:
The statement about Lucy coming over to play only when knowing about a new video game indicates a 'one way assistance' stage of friendship according to Selman's stages highlighting a unilateral benefit rather than mutual reciprocity.
Step-by-step explanation:
According to Selman's stages of friendship, the statement "Lucy will come over and play with me when she knows I have a new video game," is indicative of a friendship that is based on self-interest, which aligns with the stage of one way assistance. At this stage, the relationship is typically characterized by a unilateral perspective where one friend sees the relationship as a means of obtaining something they want or need, without necessarily considering the needs or desires of the other person involved.
The stages of friendship proposed by Selman include momentary playmates, one way assistance, two way fair weather cooperation, and intimately connected, culminating in autonomous interdependence. In the discussed scenario, since the friendship seems contingent upon the possession of a new video game, it lacks the reciprocal essence and depth found in the more advanced stages of friendship like two-way fair weather cooperation or intimate, mutually shared relationships.
