Explain Interdependence theory, comparison level and comparison level alternatives.

- theory is framed in terms of rewards that partners can provide each other in different types of situations.
- Relationship evaluations are made on the consistency b/w perception of rewards in relations to two standards;
• expectations about what benefits are deserved (comparison level)
• perceived quality of available alternative partners or rships (comparison level alternatives)
- if perceived rewards are higher than CL or CLalt = satisfied
- if below = unsatisfied, less committed
- theory also discusses the mutual influence b/w partners and interpersonal attributions
