| Outline of Final Research Achievements |
We examined whether visual statistical learning enhances memory for objects with statistical regularities and inhibits memory for those that break the regularity. In the familiarization phase, participants observed a sequence consisting of structured triplets that three items always appeared in the same order and random triplets. In the last part of the familiarization phase, Old Turkic letters were inserted into structured triplets, and between structured and random triplets. In the next memory test, participants were asked to decide whether the presented items had been shown in the prior familiarization phase. As a result, we observed that memory for the items from structured triplets was higher than that for the items from random triplets, and that memory for the letters inserted into the structured triplets was lower than that for the letters inserted into the random triplets.
