Who recognizes and chooses behaviors that are best for a relationship? The separate roles of knowledge, attachment, and motivation.

Participants made relationship decisions in several Choose Your Own Adventure-type dating story tasks by choosing between two options at each of 20 points throughout the computerized stories. One option was always the relationship-enhancing option; the other option was detrimental to the relationship. Study 1 included two experimental conditions: Participants were either asked to identify the relationship-enhancing option or to report which option they would actually choose. Individuals high in relationship knowledge were more likely to identify relationship-enhancing behaviors but not more likely to actually choose them. Secure individuals and individuals strongly motivated to have supportive relationships were more likely to identify and to choose relationship-enhancing options. In Study 2 partner supportiveness was manipulated; the fictitious partner was either supportive or nonsupportive. Individuals high in relationship knowledge were better at recognizing when a partner was supportive and when not, whereas attachment anxiety lessened the appreciation of having a supportive partner.
