Lecture 22: Language and Language Processing II Flashcards
What is psycholinguistics?
The study of the representations, mechanisms, and processes underlying language acquisition and use.
Focuses on comprehension (listening, reading) and production (speaking, writing).
What distinction did Chomsky make in psycholinguistics?
- Competence: Knowledge of linguistic structures.
- Performance: Real-world use of language, including errors.
What are the three stages of language processing?
- Words.
- Structure (syntax and parsing).
- Meaning.
1. Words
What is the mental lexicon?
- A mental “dictionary” of word knowledge.
- Questions include whether bilingual lexicons are separate or shared and if comprehension and production use the same lexicon.
1. Words
What is the segmentation problem in spoken language?
There are no clear breaks between words in speech, requiring listeners to rely on context and meaning.
1. Words
What are key processing models for words?
- Interactive Activation Model (McClelland & Rumelhart, 1981): Detectors for written letters and words activate rapidly with facilitation and inhibition.
- TRACE Model (McClelland & Elman, 1986): Similar processes for spoken word recognition.
2 Structure
What is parsing in sentence processing?
- Using rules to assign structure to sentences.
Example: A sentence has noun and verb phrases (e.g., “The chair fell over”).
2 Structure
What is sentence ambiguity?
Some sentences allow multiple interpretations (e.g., “The cop saw the man with the telescope”).
2 Structure
What are the two main theories of sentence processing?
- Garden Path Theory (Frazier):
Listeners initially choose the simplest structure, revising if wrong. - Constraint-Based Theories (MacDonald, Seidenberg, McClelland):
Multiple structures are considered in parallel, eliminating incompatible ones as the sentence unfolds.
2 Structure
What evidence supports constraint-based theories?
- Altmann et al. (1992): Referential context helped readers choose the correct structure without slowing down.
Methodology: Eye-tracking during reading.
3 Meaning
How are inferences made during language comprehension?
Inferences connect sentences using pronouns and connectives (e.g., “because,” “and so”).
3 Meaning
How do connectives influence implicit causality?
- “John charmed Bill because he had an engaging manner” focuses on John (cause).
- “John charmed Bill and so he wanted a repeat” focuses on Bill (consequence).
Study: Garnham, Child, & Hutton (2020).
Methodology: Visual world experiments tracked gaze during sentence comprehension.
How do comprehension and production differ in processing order?
- Comprehension: Words → Structure → Meaning.
- Production: Meaning → Structure → Words.
How does reading differ from listening in flexibility?
Reading allows control over processing order, while listening generally follows sentence order.
What is alignment in dialogue?
- Speakers unconsciously align linguistic output, including pronunciation, speech rate, and expressions.
Study: Wilkes-Gibbs & Clark (1992).
Methodology: Tangram naming tasks showed shared expressions developed in collaborative dialogue.
