The most immediate and basic response we have to a scent is whether we like it or not.    In scientific parlance this is referred to as odor hedonics.  Hedonic perception is an affective evaluation that centers on liking; that is our preferences.  Pleasantness, familiarity and intensity are the three factors most often evaluated when examining odor hedonic perception.   Pleasantness and familiarity are usually highly correlated in odor preference perception, whereas intensity has a more complex relationship to pleasantness (Moskowitz et al., 1976; Sulmont et al., 2002).  That is, familiar odors tend to be better liked than unfamiliar odors, and pleasant odors are often perceived as familiar.  In contrast, how strong a scent is and how it affects our pleasure of it depends on what the scent is.  For example, a weak fishy odor may be acceptable, but not a strong one.  However, a stronger lilac scent is usually preferred to a weak one (at least up to a point).
