Additionally, he classified political participation into three categories: cognitive, expressive, and organizational. Cognitive participation is how citizens obtain information about issues by watching television news, listening to the radio, talking to friends and co-workers, reading magazines, and responding to contacts from the political parties to which they belong. Cognitive participation is related to class. Therefore, the lower the socioeconomic status, the lower the rate of cognitive participation. Furthermore, because the poor are more dependent on less intellectually demanding media and belong to groups with much lower percentages, the quality of their information is lower. Expressive participation is the way citizens express opinions to others. The lower the socioeconomic status, the lower the rate of expressive participation. Since conversation is an energizing act, this means that fewer poor people and more rich people are stimulated to be active in other ways. Furthermore, the article argues that the poor are more likely to have friends who are less knowledgeable and belong to groups with fewer resources. Therefore the quality of their information is lower than that of other classes. Finally, organizational participation is based on the idea that organizations provide a forum within which people discuss issues and encourage each other to participate. Furthermore, groups often mobilize politically when their interests or those of their members are affected. Thus, acquiring information, talking to others, and joining groups provide a basis for subsequent types of action, both directly by individuals and through their collaborators..
