Subclaims¶

q2 i? Except for the object that was signalled and visually cued, the percentage of detecting the change on the most focused object was low: five of 12 participants (41.66%) detected the change in the central object. → Mutlu-Bayraktar 2018

q2 · i? · causal · r1

Eye-tracking findings for the central-object scene: five of 12 participants (41.66%) detected the change; heat maps showed participants first focused on the keyboard and some on the monitor at the moment of change.

"In the scene, in which change occurred, when the keyboard was being described, five participants out of 12 (41.66%) detected the change on the scr een (Table 1)."

• Clear Structure Improves Learning — the general claim this finding bears on, with the studies behind it

• The change on the object being verbally described was the most detected change, seen by 10 of 12 participants (83.33%) — related
• Among two objects with the same signalling, participants focused more on the arrow-cued object, and the change occurred in the un-cued object — related
• In a multimedia animation, participants focused more on signalled objects and detected fewer changes in other screen areas — related
• Changes were detected more easily on screens presenting fewer objects (66.66%) — related
• Eye-tracking results confirm that just before students articulate a new manipulation strategy, their visual attention shifts from figural screen elements to a newly invented attentional-anchor location — related
