Table 4 Memory task procedure

From: The role of a virtual avatar in attention and memory tasks in Rett syndrome

Experimental condition

Procedure

With avatar

The avatar appeared initially on the whole screen of the Tobii I-15 and said “Hi, my name is Giorgio. Watch this cartoon with me!”

Then the avatar became smaller and moved to the lower left part of the screen. During the cartoon, it only moves its eyes and head in a stereotyped way to make the avatar seem alive.

After watching the first cartoon, the avatar appeared again and says “Hello, we will play together now!”

Then the avatar started by asking the participant the 8 questions. Participants had to choose the correct answer with their eyes and avoid focusing on the distractor.

Then the avatar appeared again and repeated the process with a second video.

Without avatar

No avatar was presented to participants. The story-cartoon was presented with Tobii eye-tracker.
