Equity Theory Ratios as Causal Schemas.

Area of Science:

• Social Psychology
• Cognitive Psychology
• Behavioral Economics

Background:

• Equity theory traditionally evaluates justice based on input-output ratios.
• Situations are deemed just when ratios are equal and unjust when unequal.
• This study explores a more fundamental cognitive role for equity ratios beyond justice evaluations.

Purpose of the Study:

• To propose that equity ratios function as causal schemas for exchange outcomes.
• To investigate if equity ratios help determine if outcomes are caused by others' inputs in exchanges.
• To differentiate the cognitive processes of attribution and evaluation in exchange outcomes.

Main Methods:

• Study 1 examined perceptions of give-and-take in various exchange situations (disproportional, balanced proportional) using equity ratios.
• Study 2 investigated the basis of justice perceptions, comparing equity-based evaluations with communicatively accepted rules of interaction.

Main Results:

• Study 1 demonstrated that different exchange situations generate perceptions of give-and-take based on equity ratios.
• Study 2 indicated that justice perceptions rely more on interaction rules than on equity-based assessments.
• A distinction was observed between attribution (causal schema) and evaluation (justice) cognitive processes for exchange outcomes.

Conclusions:

• Equity ratios serve as fundamental causal schemas for understanding exchange outcomes.
• Perceptions of justice in exchanges are influenced by interaction rules, distinct from equity ratio evaluations.
• The study differentiates the cognitive attribution of outcomes from their subsequent evaluation regarding justice.
