Secondary Task Performance

From EuroVR Knowledge Base

Description

Performance on a secondary task can serve as a measure for the amount of effort allocated to the primary task. The more effort that is dedicated to the primary task, the more performance on the secondary task will decrease. A similar argument can be made in the case of presence: if more attention is allocated to the mediated environment, performance on a secondary task will decrease. Reaction times or error rates can be used as secondary task performance measures (IJsselsteijn, 2004),
