Typing in the Missing Letter

SKILL: Writing

DIFFICULTY: 1/5

LEVELS: 12 based on word length and position of the missing letter

BRIEF RATIONALE: This treatment is a step toward typing words that relies upon reading skills to aid writing.

In Typing in the Missing Letter, you will see a picture, hear a word, and see the incomplete written word. You will type in the missing letter using the keyboard. You can replay the audio at any time using the audio button. You can also expand the image using the arrows in the lower-right corner. The treatment auto-adjusts in difficulty based on performance.


HINT: A hint button is available in the lower-left corner of the screen to hear the missing letter name. Using the hint will mark the item as incorrect (as it was not answered independently), but may help you find the missing letter.

FOR THE CLINICIAN: This treatment involves phoneme-to-grapheme conversion (PGC), meaning the patient must convert a sound to a letter to complete the word. The purpose of this PGC task is to improve spelling and writing abilities.
