WIAT Orthographic Processing Skills 5 — Questions and Answers
Question 1: A student struggles specifically with homophones (e.g., writing 'there' for 'their'). This error pattern reflects a deficit in:
- Phonological awareness
- Morphosyntactic knowledge only
- Orthographic differentiation of words with identical pronunciations (Correct answer)
- Rapid automatized naming
Correct answer: Orthographic differentiation of words with identical pronunciations
Confusing homophones demonstrates an inability to maintain distinct orthographic representations for words that sound the same, a core orthographic processing challenge.
Question 2: Which characteristic of English orthography makes it more demanding than shallow orthographies like Spanish or Finnish?
- English has fewer phonemes than other languages
- English has many irregular spellings where sound-letter correspondence is inconsistent (Correct answer)
- English words are longer on average
- English uses a non-alphabetic script for common words
Correct answer: English has many irregular spellings where sound-letter correspondence is inconsistent
English's deep orthography contains many words whose spellings cannot be reliably derived from pronunciation alone, increasing the demands on orthographic memory.
Question 3: A WIAT evaluator notes a student correctly reads 'sign' aloud but spells it 'sine.' Which process is intact and which is impaired?
- Both reading and spelling orthographic processes are impaired
- Orthographic input (reading recognition) is intact; orthographic output (spelling retrieval) is impaired (Correct answer)
- Orthographic output is intact; orthographic input is impaired
- Neither process is impaired; this is a normal developmental error
Correct answer: Orthographic input (reading recognition) is intact; orthographic output (spelling retrieval) is impaired
Correct reading of 'sign' shows the visual pattern is recognized, but the spelling error reveals that the complete stored representation cannot be fully retrieved for production.
Question 4: Which brain region is most consistently implicated in orthographic word-form storage?
- Broca's area in the left inferior frontal gyrus
- The visual word form area in the left occipito-temporal cortex (Correct answer)
- The right cerebellum
- The bilateral anterior temporal lobes
Correct answer: The visual word form area in the left occipito-temporal cortex
The left occipito-temporal region, often called the visual word form area or 'letterbox area,' is specialized for storing and rapidly recognizing whole-word orthographic patterns.
Question 5: When interpreting WIAT results, a pattern of average reading comprehension but below-average spelling most likely indicates:
- A global language processing disorder
- Selective orthographic output deficit with compensatory comprehension strategies (Correct answer)
- Primarily a vocabulary deficit
- A working memory deficit affecting only written production
Correct answer: Selective orthographic output deficit with compensatory comprehension strategies
Good comprehension with poor spelling suggests the student can extract meaning from text but lacks accurate orthographic output representations needed for correct spelling.
Question 6: According to Frith's stage model of literacy development, the stage at which children begin storing whole-word orthographic representations is called the:
- Logographic stage
- Alphabetic stage
- Orthographic stage (Correct answer)
- Morphographic stage
Correct answer: Orthographic stage
In Frith's model, the orthographic stage is when readers move beyond sequential letter-by-letter decoding to recognize whole words as visual units stored in memory.
Question 7: A student excels at spelling phonetically regular words (e.g., 'stamp,' 'blend') but struggles with irregular high-frequency words (e.g., 'colonel,' 'Wednesday'). This profile best indicates:
- Strong orthographic processing with weak phonological skills
- Weak phonological skills with strong orthographic processing
- Strong phonological skills with weak orthographic lexicon for irregular words (Correct answer)
- Deficits in both phonological and orthographic systems
Correct answer: Strong phonological skills with weak orthographic lexicon for irregular words
Success with phonetically regular words shows intact phonological decoding, while failure on irregular words reveals an orthographic lexicon that lacks accurate representations for words that cannot be spelled by sound alone.
