Linguistics
The process of finding lexical items from the mental lexicon
What is lexical access?
The impairment in linking meaning to sound in production
What is anomia?
The MEG brain component correlated with lexical access
What is the M350?
The brain component we were interested in during our Two Tones experiment
What is the auditory M100?
A memorized representation, like the concept of a cat
What is lexical item?
The deficit in linking sound to meaning in comprehension (without any evidence of phonological or semantic impairment)
What is TSA (Transcortical Sensory Aphasia)?
The machines that are not good enough to study lexical access
What are fMRI and PET (hemodynamic methods)?
The reason why participants cannot wear metal inside an MEG
What is a disruption of the data?
The "dictionary" of lexical items in the brain
What is the mental lexicon?
The brain area affected in TSA patients
What is the left middle temporal cortex?
Two factors that can affect lexical access
What is frequency, (predictability based on) context, recency of use, priming?
The activation prediction of the 1000Hz tone, in relation to the 250Hz tone
What is a shorter latency, higher amplitude?
Words that are activated together because they sound alike
What are phonological neighbors?
The difference between TSA and Wernicke's aphasia
What is the ability to repeat words (in TSA)?
The EEG brain component elicited by semantic surprise based on previous context
What is the N400?
MEG experiments on lexical access usually use _______ ________ as a behavioral task
What is "lexical decision"?
Words that are activated together because their meaning is related
What are semantic relatives?
In science, we need to be mindful of the difference between correlation and _________. TSA induction (cortical stimulation) allows us to have _______ data
What are "causation" and "causal" data?
The ease of accessing a lexical entry depends on this entry's ________ _____ __ __________ prior to access
What is the "resting level of activation"?
If we were to study phoneme categorization in an MEG experiment, it would be hard to cross a phonemic boundary without also creating a ________
What is a physical distance between the sounds?
