6 - from mind to mouth Flashcards
What ERP component is also called the no-go potential?
N200
With what task can we test the temporal aspects of speech production?
Doing a go/nogo task and differing whether the decision depends on semantic or phonological information.
What is the serial or cascade model of speech production?
Early visual encoding, semantic encoding and phonological encoding
How do we know LRP and N200 are independent?
LRP is not present at frontal sites, N200 not present at central sites.
N200 precedes the LRP.
Unlikely that the two influence each other or measurement of one of them is contaminated by overlap from the other.
Both semantic and phonological processing might start at the same time. What evidence do we have for this?
LRP - steeper slope in go = semantics than go = phonology which is consistent with faster and/or easier semantic processing.
N200 amplitude is higher in go=semantic condition, which is associated with faster semantic processing.
What is the evidence for serial and cascading models of speech production?
Semantic information is available early than phonological information.
What are sound errors?
Sound errors occur at the phonological processing stage. In this error one switches syllabic components of words or letters. the slots and filler theory states that speech errors occur because one misfills the slots of certain syllables within a sentence
What are standing errors?
Standing errors take place at the syntactical stage. This is the switching up of morphemes (suffix, prefix and word stem). (fancy getting your model renosed)
What are word exchanges?
Appear at semantical processing stage. Words within sentences get exchanged but the conceptual meaning of the sentence is kept (chats in clap)
