A factor related to the strength of an "Aha!" experience

Abstract: It is natural to assume that the strength of an "Aha!" becomes stronger when an unexpected solution is correct. In this study, this assumption is examined experimentally through a list of possible correct solutions. In the experiment, subjects listed the possible correct solutions before solving the problems, and evaluated the strength of their "Aha!" experience after they solved the problems. It was shown that the strength of the "Aha!" experience was strongest if the correct answer had not been included in the list of possible correct solutions; if included, the strength of the "Aha!" experience corresponded to the answer's position in the list, that is, the later the correct solution listed, the stronger the feeling became. It is suggested that the strength of an "Aha!" experience can be used as an error function in the learning process.     

When does anger evoke self‐interest and fairness motives? The moderating effects of perceived responsibility for needs

Research has repeatedly demonstrated that anger evokes both self‐interest and fairness motives, but it is unclear what factors determine the evocation of these motives. We examined the idea that the type of relationship, indexed by the perceived responsibility for a partner's needs, moderates the effect of anger on self‐interest and fairness motives by constructing the following hypotheses: Participants will be motivated to protect their self‐interests when they feel anger toward an other who they perceive has the responsibility for needs, while this will not be the case when they feel anger toward an other who they do not perceive has a responsibility for needs (Hypothesis 1), and participants will be motivated to restore fairness regardless of whether the target of anger has a responsibility for needs or not (Hypothesis 2). The Japanese participants in this study rated their anger experiences in terms of the intensity of angry feelings, the perception of responsibility of the other for their own needs, the closeness of the relationship prior to the experience of anger, and the motives that were evoked. Regression analysis supported both hypotheses, implying that concerns related to self‐interest in close relationships reflect the desire for the maintenance of these relationships.
