also illustrates how people contrast their personal positions on issues to others' positions around them. Aside from having their personal opinion, individuals hold latitudes of what they think is acceptable or unacceptable in general for other people's view. Social attitudes are not cumulative, especially regarding issues where the attitude is extreme. This means that a person may not agree with less extreme stands relative to his or her position, even though they may be in the same direction. Furthermore, even though two people may seem to hold identical attitudes, their "most preferred" and "least preferred" alternatives may differ. Thus, a person's full attitude can only be understood in terms of what other positions he or she finds acceptable or unacceptable, in addition to his or her own stand. Sherif saw an attitude as amalgam of three zones or latitudes. There is the latitude of acceptance, which is the range of ideas that a person sees as reasonable or worthy of consideration; the latitude of rejection, which is the range of ideas that a person sees as unreasonable or objectionable; and, finally, the latitude of noncommitment, which is the range of ideas that a person sees as neither acceptable nor questionable. These degrees or latitudes together create the full spectrum of an individual's attitude. Sherif and Hovland (1961) define the latitude of acceptance as "the range of positions on an issue ... an individual considers acceptable to him (including the one 'most acceptable' to him)" (p. 129). On the opposite end of the continuum lies the latitude of rejection. This is defined as including the "positions he finds objectionable (including the one 'most objectionable" to him)". This latitude of rejection was deemed essential by the SJT developers in determining an individual's level of involvement and, thus, his or her propensity to an attitude change. The greater the rejection latitude, the more involved the individual is in the issue and, thus, harder to persuade. In the middle of these opposites lies the latitude of noncommitment, a range of viewpoints where one feels primarily indifferent. Sherif claimed that the greater the discrepancy, the more listeners will adjust their attitudes. Thus, the message that persuades the most is the one that is most discrepant from the listener's position, yet falls within his or her latitude of acceptance or latitude of noncommitment. Assimilation and contrast Sometimes people perceive a message that falls within their latitude
