paging vs. scrolling for content : overall summary - scrolling is better then paging.

Evaluation of the average time (in seconds) taken to read each passage revealed a significant difference between the three groups [F (2,28) = 3.42, p < .05] (S.D. Paging = 72.4, S.D. Full = 53.5, S.D. Scrolling = 57.89; See Figure 4). Post hoc analysis found reading time in the Paging condition to be significantly slower than the Full or Scrolling conditions.
