According to Maclver an attitude is not a static possession of the individual. It is always a changing valuation a way of regarding persons or things, a way of assessing them in relation to them. Maclver places attitudes in three main categories - Dissociative, restrictive and associative. Dissociative attitudes are those that tend to deter men from friendly relationship.
Restrictive attitudes are those that limit the social relationship whereas attitudes that promote the social relationship may be termed as associative. These attitudes imply in the relationships of the persons affected by them inferiority feeling or superiority feeling or have no such implication.
