Subclaims¶

q2 i? Participants viewing videos from which event boundaries had been deleted recalled a lower proportion of subevents than participants viewing other versions. → Spanjers 2010 q2 i? Inserting commercials between event boundaries reduced recall of a mini-series episode, while inserting more commercials at event boundaries had a positive effect on recall. → Spanjers 2010 (2)

q2 · i? · review · r3

The review reports Schwan and Garsoffky's (2004) experiment with videos of cleaning a pistol or upgrading a computer, unaltered or with black screens replacing event boundaries or parts between them; the boundary-deleted version yielded lower recall of subevents. No effect size is printed.

"Moreover, participants who viewed the video from which event boundaries had been deleted recalled a lower proportion of the subevents than the participants from the other groups, which might be due to disruption of the event structure, reduced coherence of the video, and a lower proportion of relevant steps shown."

The review reports Boltz's (1992) experiment showing an episode of a mini-series with commercials inserted at or between event boundaries; the between-boundaries version was recalled less well. No effect size is printed.

"She hypothesized that insertion of commercials between event boundaries would hinder perceiving the underlying event structure of the episode. Her results were in line with this hypothesis: Participants who saw this version recalled less from the episode than participants who saw another version."
