The cognitive syle characteristics of the standard default PP presentation: foreshortening of the evidence and thought, low spatial resolution, a deeply hierarchical single-path structure as the model for organising every type of content, breaking up of the narrative and data into slides and minimal fragments, rapid temporal sequencing of thin information rather than focused spatial analysis, conspicuous decoration and Phluff, a preoccupation with format not content, and an attitude of commercialism that turns everything into a sales pitch.
