4. TITZER, R. (1997). Case Study of a Second Infant Learning Written Language. (Unpublished study on Keelin Titzer).
Keelin began viewing her reading video on June 15, 1994 at the age of two months, 0 days. On average, she watched the video for about 45 minutes per day. Keelin did not watch any other TV programs or videos in early infancy. Keelin could demonstrate the meanings of seven consecutive written words without hearing them when given recall tests at 8 months of age. In other words, when the word “clap” was shown to her – she consistently would clap. When she saw the word “wave” she would wave her hand.
By 12.5 months of age, Keelin would generally turn her head upside down when shown a long word (five or more letters) that was upside down. This appeared to demonstrate that she had learned a general pattern of what words look like and she recognized when the individual or groups of letters in a long word did not fit that pattern.
Keelin became skilled at matching toys or objects with the written words that represented the toys or objects. By 15 months of age, when four words were scattered on the floor where she could see them and she was handed a small toy/object that matched one of the words, she would take the object and place it on or next to the corresponding word. By 18 months of age, when Keelin was given two novel written words – for example “newspaper” and “computer” – she would consistently point to the word that was spoken. This appeared to show that Keelin had learned some phonetic patterns by 18 months of age.
