Here I am going to be drawing upon scholarship of Walter Ong and others who distinguish the characteristics of oral societies with those which are dominated by writing—and Europe and the United states are thoroughly dominated by the written culture even though oral culture is still with us because orality is deeply and intrinsically human; all human societies are also oral cultures. Primary orality refers to cultures which are untouched by writing whereas residual orality is cultures like ours where writing dominates even our speaking.
In oral psychodynamics, the conversational, formulaic styling dominates (which aides memory) as well as back-and-forth, redundancy, an emphasis on being less analytic and more aggregative, being more additive rather than developing complex and subordinate clauses (classic example is the Genesis which, like Homer’s Odyssey, is indeed an oral work which was later written down). Oral pschodynamics also tend to be more antogonistic, interpersonal and participatory.
