Lecture 9: Writing Disorder And Motor Speech Disorder

Question 1

Planton, 2017: handwriting

Answer 1

GMFA and ISLP underlie peripheral processes of writing

Question 2

Brain activation on drawing

Answer 2

Bilateral superior parietal cortex, supplementary motor area, parts of the premotor cortex and the cerebellum

Question 3

Planton, 2017: results

Answer 3

1. Handwriting and drawing similarly recruited similar brain network
2. Handwriting and oral spelling recruited different brain areas
3. SPL similarly activated across drawing and handwriting
4. GMFA shows different activation profiles across handwriting and drawing
5. Posterior cerebellum similarly activated across drawing, handwriting and spelling

Question 4

Imageability effects

Answer 4

More imagegable have richer semantic interpretations

Question 5

Age of acquisition effect

Answer 5

Damage to link between semantic and orthographic word forms with earlier acquired items being more robust to damage to graphemic buffer

Question 6

Frequency effect

Answer 6

More robust representations formed for high frequency words

Question 7

Orthographic neighborhood effect

Answer 7

Words with large N supported by more lexical activation

Question 8

Results of patient BH, priming experiment

Answer 8

BH benefited from orthographic neighbor primes compared to control primes for target word spelling

Question 9

What is speech motor control?

Answer 9

Strategies controlling production of speech

Question 10

Dysarthria of speech

Answer 10

Impairment in muscular control/execution

Question 11

Apraxia of speech

Answer 11

Impairment in motor planning of language

Question 12

The cerebellum is involved in

Answer 12

Attention, memory, language and motor control

Question 13

Lesions to te cerebellum linked to speech motor impairment:

Answer 13

Ataxic dysarthria

Question 14

lesions of ataxic dysarthria

Answer 14

Superior regions of cerebellum

Question 15

Apraxia of speech
