How The Phonological Deficit Hypothesis Is Supported Using Evidence From Genes And Brains Flashcards
Richlan (2012) what does he do
Meta analysis on studies of dyslexics
Richlan (2012) what did he find
Under-activity in LH reading network regions associated with phonological processing and whole word recognition (VWFA)
Over active left inferior frontal gurus - this acsesses phonological output representations - suggests getting them is over effortful
What does richlan 2012 show
Weaker activation in phonological processing abilities = could suggest a deficit in phonological processing
What is the point made by Richlans 2012 study
Brain evidence found that demonstrates a dysfunction in the left hem reading network
Van Der Mark (2011) what did he do
Got participants to do a continuous reading task and used FMRI scans to monitor brain activity
What did Van der Mark (2011) find
Dyslexics had disrupted connectivity between VWFA and Left inferior frontal/parietal language as
What did Van der Mark (2011) show
Rejoins associated with phonological processing have disrupted connections in dyslexics
What is the point made by van der marks (2011) study
Brain evidence shows that dyslexics have disrupted functional connectivity in rejoins associated with phonological processing
What did Heim (2015) do
Training interventions to improve phonology
What did heim (2015) find
Phonology training improved reading in dyslexics
Also phonology training and improved reading corresponded with brain activity increases in VWFA
What does heim (2015) results show
Phonology interventions created increased activation in VWFA in dyslexics
If training in phonology lead to more irregular brain activation suggests that’s where the deficit lied
What is Heim (2015) point for an essay on phonology
Brain evidence has shown phonology training is related to better reading and more regular activation patterns
