Glossary
acceptance, latitude of: the range of message positions that are acceptable, or plausible, to an listener; includes the listener’s own attitude (at the center of the latitude of acceptance) and those message positions on that topic close to that attitude

assimilation: a perceptual process in which a message which is actually close to an listener’s own attitude (in the latitude of acceptance) is misperceived as closer to the attitude than it really is

contrast: a perceptual process in which a message which is far away from an listener’s own attitude (in the latitude of rejection) is misperceived as further from the attitude than it really is

curvilinear: a relationship that is not a simple, straight line; increases in the size of one variable (discrepancy) first create increases in another variable (persuasion), but further increases in the first variable cause decreases in the other variable*

discrepancy: the amount of difference between a message and a listener’s own attitude
involvement: the extent to which a topic is relevant, important, or salient to an listener

non-commitment, latitude of: the range of message positions that the listener neither accepts nor rejects; there may be one latitude of non-commitment between the latitudes of acceptance and rejection, or two latitudes of non-commitment, one on each side of the latitude of acceptance

rejection, latitude of: the range of message positions that the listener rejects; there can be one or two latitudes of rejection; when the latitude of acceptance is near either end of the attitude/message continuum there will only be one latitude of rejection

*Strictly speaking, I should not use the words “create” or “cause” here because causation is very difficult to prove. I should have said something like “increases in one variable are first associated with increases in a second variable, and further increases in the first variable are associated with decreases in the second variable.”
