Question 1

Which brain imaging finding is most consistently associated with dyslexia in neurological research?

Accepted Answer

Reduced activation in left temporoparietal regions during reading

Answer

fMRI studies consistently show reduced activation in left temporoparietal areas (including the angular gyrus and Wernicke's area) in individuals with dyslexia during reading tasks.

Question 2

The 'Simple View of Reading' (Gough & Tunmer, 1986) defines reading comprehension as the product of which two components?

Accepted Answer

Decoding and linguistic comprehension

Answer

The Simple View of Reading formula is RC = D × LC, meaning Reading Comprehension equals Decoding multiplied by Linguistic Comprehension.

Question 3

Dyscalculia that co-occurs with dyslexia is best described as which type of comorbidity?

Accepted Answer

Comorbid condition sharing some neurological risk factors

Answer

Dyscalculia and dyslexia frequently co-occur and share some genetic and neurological risk factors, though they also have distinct etiological pathways.

Question 4

Which term describes the phenomenon where a child with dyslexia reads words correctly but very slowly and with great effort?

Accepted Answer

Dysfluent decoding

Answer

Dysfluent decoding refers to accurate but labored, slow word reading that still reflects the core deficit in phonological processing even when accuracy improves.

Question 5

According to the IDA definition, which of the following is NOT a primary characteristic of dyslexia?

Accepted Answer

Difficulties with reading comprehension caused by poor listening comprehension

Answer

The IDA definition specifies that reading comprehension difficulties in dyslexia result from deficits in phonological processing, not from poor listening/language comprehension (which would indicate a different profile).
