TL;DR: The Inclusion of Other in the Self (IOS) Scale, a pictorial measure of closeness, demonstrated alternate-form and test-retest reliability; convergent validity with the Relationship Closeness Inventory (Berscheid, Snyder, & Omoto, 1989), the Sternberg (1988) Intimacy Scale, and other measures; discriminant validity; minimal social desirability correlations; and predictive validity for whether romantic relationships were intact 3 months later.

TL;DR: The cognitive significance of being in a close relationship is described in terms of including other in the self as mentioned in this paper, in Lewin's sense of overlapping regions of the life space and in James's sense as resources, perspectives, and characteristics.

TL;DR: The extended contact hypothesis as mentioned in this paper proposes that knowledge that an in-group member has a close relationship with an outgroup member can lead to more positive intergroup attitudes, and four methodologically diverse studies to demonstrate the phenomenon.

TL;DR: The results suggest that romantic love uses subcortical reward and motivation systems to focus on a specific individual, that limbic cortical regions process individual emotion factors, and that there is localization heterogeneity for reward functions in the human brain.

TL;DR: Male passersby were contacted by an attractive female interviewer who asked them to fill out questionnaires containing Thematic Apperception Test pictures, and sexual content of stories written by subjects on the fear-arousing bridge and tendency of these subjects to attempt postexperimental contact with the interviewer were both significantly greater.
