Final answer:
The 'turning point' model best describes the changing nature of relationships through significant events. This concept is part of the family life course framework, which recognizes fluid progression in relationships, and aligns with theories that highlight how regular contact influences relationship formation.
Step-by-step explanation:
Understanding Relationship Development Models
The model of relationship development that describes people's relationships as changing based on important positive and negative events is known as the turning point model. This model suggests that relationships evolve through significant moments or events that either improve or deteriorate the connection between individuals. It aligns with the broader concept of the family life course, a sociological model that views family progression as fluid rather than strictly stage-based. It also reflects modern social theories that recognize the influence of proximity on forming friendships and romantic relationships, where regular contact with others increases the likelihood of relationship development.
Within the realm of relationship development, various factors such as societal changes, personal interactions, and the individual characteristics of the people involved play crucial roles. These include but are not limited to proximity, similarity, mutual interests, and significant life events. Understanding these dynamics can help in explaining why some relationships strengthen over time while others may falter.
