With inadequate observing, individuals make errors in placing Kanji parts accurately, producing mirror writing or retrography (Sato, 1997; Suzuki et al., 2010).
The three students with developmental disabilities and one of the TD students often demonstrated retrography in producing Kanji.
All students began training with the SSP procedure because four students demonstrated retrography when they were instructed to write Kanji words.
Ami (panel e) was the only participant without a history of retrography. She required 2.32 (range, 2 to 3) blocks after the SSP procedure and scored 100% for both follow-up tests.
AMI, who did not exhibit the retrography, required fewer training blocks in the SSP procedure than the SP procedure, just as the four students with retrography.
