Lecture 2 - Language Learning Disorders Flashcards
What are the two types of Perceptual Analysis?
Auditory (Hearing sounds)
Visual (Seeing letters and words)
Children with Auditory or Vision deficits may also have _____ and _____ language deficits too.
Spoken
Written
What is Phonetic Discrimination?
Ability to hear difference between two sounds that differ acoustically and phonetically
(T in tap and t in bat – differ phonetically, but don’t change meaning (allophones)
T and k differ phonetically and do change meaning)
What is Detection?
Ability to perceive the signal
What is Discrimination in Reading?
Ability to see visual differences between letters
E.g., /b/ vs /d/
What is a Visual Discrimination Problem?
What will this negatively impact? (2)
If can’t tell differences between letters
Decoding and writing
What is Identification?
Knowledge of the correspondence between letters and phonemes
A child who reads words wrong may have an ______ problem or a ______ problem.
This means we need to assess both _____ and _____.
Identification
Discrimination
Discrimination
Identification
What are the 3 types of Word Recognition?
Phonological Representation
Word Meaning
Visual Representation
What do we need to understand Sentences?
Text Processing
What is Comprehension?
Understanding what is being said and read
Words that are seen or heard must be associated with stored concepts in the __________.
Mental Lexicon (vocabulary)
Content of Mental Lexicon is same for _____ and _____.
Reading
Spoken language
What is contained in one’s mental lexicon?
4
Visual form
Phonological Information
Semantic Information (word meaning and relation to other words)
Syntactic information (noun, verb, adjective, etc.)
What happens when we process speech?
What happens as children age?
The phonological representation is directly linked to semantic meaning
They become more sensitive to native language sounds
What are the two paths we use to understand written words?
What is the other path?
Directly
Indirectly
Dual Route Model
What type of stimulus is used in the Direct path for reading?
What is it in a nutshell?
Visual representation
Look and say – whole word processing for sight words/familiar words
What is the Direct Model for reading?
6 + 1
Visual Input ->
Visual Analysis ->
**Visual/Lexical Decoding
**Word Meaning
Sentence/Text Processing ->
Text Meaning
**May be skipped using Sound-Symbol Associations
What type of stimulus is used in the Indirect Model for reading?
What is it in a nutshell?
Phonological representation
Decode words sound by sound, then blend together – takes longer
What is required to use the Indirect Model for reading?
2
Attention to letter sequences in words
Must have knowledge that words have discrete phonemic segments (Liberman, 1983
What is the Indirect Model for reading?
6
Auditory Input ->
Auditory Analysis ->
Phonological decoding ->
Word Meaning
Sentence/Text Processing ->
Text Meaning
What is the Dual Route Model for reading?
We use both the visual/lexical, and phonological routes for word recognition
What is Discourse Level Processing?
1 + 4
Processing…
- Sentences
- Conversations
- Lectures
- Stories
What are the different types of Structural Knowledge?
4
Word Order – Subject + Verb + Object – statements
Questions – Verb + Subject?

(1 + 4)
Trouble with…

- Following directions
- Answering questions
- Etc.
What is a Proposition?
An Idea-unit that has a predicate (verb) and related arguments
(E.g., give – someone giving, object given, recipient of object)
What can deficits in Propositions impact?
4
Composition of sentences
Understanding the meaning of sentences
Sentence structure
Understanding or sequences of information
What are the types of World Knowledge?
4
Situation Model Representations
Specific Content Domains
Procedural Knowledge
Interpersonal Knowledge
What are Situation Model Representations?
Individual’s knowledge of the world aids in comprehension
