Filling 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 spelling words using reading skills to aid writing.

In Filling in the Missing Letter, you will see a word that is missing one letter and drag the missing letter tile into place. The treatment auto-adjusts in difficulty based on performance.


HINT: A hint button is available in the lower-left corner of the screen to reveal the correct letter in the first available space. Using the hint will mark the item as incorrect (as it was not answered independently), but may help you complete the word.

FOR THE CLINICIAN:

Besides word length, the position of the missing letter can influence task difficulty. Because most of the word is provided, the overall demand for selecting a single missing letter is relatively low.


Patients may draw on several mechanisms to complete the word, including sounding it out through phoneme-to-grapheme conversion, accessing whole-word orthographic knowledge via the lexical route, applying familiar spelling patterns, and/or using trial and error.
