Set-size effects play an important role in theories of visual attention and the effects of attentional load upon performance. Visual search theories attribute slower response times to changes in absolute set size. Recent studies have implied that the set-size effects could originate from changes in relative set-size (e.g. the target-to-distractor ratio). Using an iPad foraging task we measure the effects of relative and absolute set size. Participants were required to complete tasks where either relative set-size or absolute set size were altered. Results show that manipulations of relative set-size have an effect beyond absolute set-size.
