Conjunctivochalasis (CCh) Overview. Conjunctivochalasis (CCh) represents one of the most common age-related eye diseases and is characterized by the presence of redundant folds of the conjunctiva that typically are detected between the eyeball and the eyelids.
Reciprocity of liking (also known as reciprocity of attraction and reciprocal liking) describes the tendency for individuals to think positively of others who express positive regard for them.
Reciprocity is so strong that a person will feel obligated to return a favor regardless of whether they like the person who originally gave the favor and even if they did not want the favor, as was demonstrated in an experiment by Dennis Regan in 1971.
