Final answer:
In social psychology, a perceived incompatibility of goals indicates conflict, which occurs when individuals or groups have conflicting objectives that they believe cannot be achieved simultaneously.
Step-by-step explanation:
To a social psychologist, a perceived incompatibility of goals indicates conflict. This situation arises when two or more parties believe that their goals are mutually exclusive, leading to a struggle or potential interference with one another's attempts to achieve these goals. This concept is distinct from others such as group polarization, which refers to the strengthening of the original group attitude after discussing views within the group, and the frustration-aggression principle, which suggests that frustration can lead to aggression as an attempt to achieve a blocked goal. Moreover, social loafing occurs when individual members of a group exert less effort than when working alone, and prejudice involves negative attitudes towards others based on their membership in specific social groups.
