摘要：The aim of this study was twofold: one was to test the impact of the involvement on the parental outcome bias, and the second was to
refine the measurement of outcome bias, normally reported as the difference between evaluations of a single decision, with different
outcomes assigned to it. We introduced the evaluation of a decision without an outcome, to induce theoretically normative evaluation,
unbiased by outcome, from which the evaluation shift could be calculated in either direction. To test this refinement in the parental decisionmaking
context, we produced childcare dilemmas with varying levels of complexity, since the rise of complexity induces stronger bias.
Complexity was determined by the particular combination of two factors: parental involvement in a decision - the amount of motivation,
interest and drive evoked by it – and whether the decision was health-related or not. We presented parents with the decisions for
evaluation, followed by a positive and a negative outcome, and without an outcome. The results confirm the interaction between
involvement and domain on decision evaluation. Highly involving decisions yielded weaker outcome bias than low-involvement decisions in
both health and non-health domain. Results also confirm the validity of the proposed way of measuring OB, revealing that in some
situations positive outcomes skew evaluations more than negative outcomes. Also, a highly-involving dilemma followed by negative
outcome did not produce significantly different evaluation compared to evaluation of a decision without outcome. Thus, adding a neutral
position rendered OB measurement more precise and our involvement-related insights more nuanced.
