gain–loss theory

a theory of interpersonal attraction stating that people’s like (or dislike) for another person is more strongly affected by the degree to which they believe they have gone up (or down) in that individual’s estimation than by the unvarying degree to which they think they are attractive (or unattractive) to that person. [first studied in 1965 by U.S. psychologists Elliot Aronson (1932– ) and Darwyn E. Linder (1939– )]

sun compass

the use of the sun as a directional stimulus in orientation and navigation. Because the sun appears to move across the sky during the day and has different trajectories in different seasons, a sun compass must be coupled with some form of time estimation. To head south at 9 a.m., one needs to keep the sun on the left, but at 3 p.m., one needs to keep the sun on the right. Studies of several species, ranging from bees to fish and birds, have demonstrated a time-compensated sun compass. For nocturnal species, there is evidence of a star compass.
