Normal
-not expectedly different from average
Slip of the Tongue
-most common speech error
-when we say something we didn’t mean to, scrambling the order of the sounds or words or putting in a wrong word
Tip of the Tongue
-can’t find a word, especially a name, that you know and want, and at best can only come out with an approximation to it
-lexical retrieval
Lexical Retrieval
-how we activate a content word when we need it
Mondegreen
-misanalysis of a phrase that you have heard frequently, typically from a song
Melapropisim
-fusing or confusing two words that have similar sounds and using one of them where the other is appropriate (jeopardize instead of deputize)
-these errors are stored in memory rather than one time events
-part of their mental lexicon
Slip of the Ear
-misanalysing a word or phrase as you hear it
-many mondegreens and malapropisms begin as slips of the ear that got lodged in a person’s memory
Normal Speaker
-normal is a spectrum
-an adult speaker/reader w/no detectable foreign accent and no detectable language comprehension or production problems other than occasional slips of the tongue
-normal also depends on context
-has already acquired language
People not considered to be Normal Speakers
-first language learners
-second or later language learners
-people w/developmental disorders, dyslexia, or brain damage, early onset HL
-people w/late onset HL
First Language Learners
-a child who is becoming a speaker of at least one language = typically developing
Second (or later) Language Learners
-past early childhood and learning a second language
-first language may impact the learning of the second
People w/Developmental Disorders, Dyslexia, Early Onset HL, Or Brain Damage
-people who are not developing or learning normally and people with developmental language disorders
People w/Late Onset HL
-people who lose their hearing as adults
-may use bottom up processing via visual information from lip reading
-severe loss may have abnormal pitch and loudness because of not being able to hear themselves
Message Level
-process concerned w/choosing what, of all that’s currently in your mind
-overarching concepts
-brain choosing what to put into words
-picking stories angle, activating people and things that need to be mentioned, and organizing what happened into event structures (who did what to whom)
-not yet language processing
-like thinking of a new invention before giving it a name
-choices at this level like who are you talking to
-what details do you recall/how well do you recall the impacts (arousal of content)
Functional Level: Lemmas
-lemma: the meaning of a word, without it’s sounds
-a word’s lemma is its meaning plus the information that your mind needs to use it in making sentences
-meanings as your mind made it
Relations between Concepts (Semantic Categories)
-semantic category: things or word that create similar meanings
-category names tells us how we can expect something to behave or how we behave toward it
-categories at work in brains as we speak and listen
-categories shaped by own experiences, most things belong in more than on category
What do concepts/semantic categories activate?
-their lemmas
-concepts that are related to lemmas (antonyms or opposites, within category substitution errors)
Spread of Activation for Normal Speakers
-limited: stays within semantic category boundaries for the most part
Spread of Activation for Aphasic Speakers
-also have limited spreading activation
-occassional exceptions in mild aphasia
-dramatic exceptions for severe aphasia (circumlocutions)
Broca’s Aphasia and Lemmas
-receives lemmas but trouble ordering them
Wernicke’s Aphasia and Lemmas
-trouble selecting lemmas or getting lemmas to Broca’s area
-semantically related words are activated which can result in lemmas being selected that aren’t what you wanted
Blend Errors
-parts of two words or phrases tried to get out at same time and were mixed together
-I lost my track of thought (train)
-both lemmas were strong enough to call up their phonological forms at the same time
How do lemmas find the place in the sentence where they belong?
-linking lemmas w/semantic functions that correspond to the roles in our message
-agent, undergoer, theme, recipient, location
