Language Production
Date: Nov 5, 2024
Course: PSYC 145 Guest Lecture by Thomas Morton
Content: "Who am I?"
Reasons to study language production
Methods of studying language production
Definition of speech error
Insights from speech errors on production mechanisms
Process of speaking: From intention to articulation
Preparatory orientation before speaking
Planning duration and its constraints
Impact of past experiences on future production
Word recall difficulties
Nature of speech mistakes
Variance in mistakes and error recognition
Comprehensive models of speech production
Language is a complex, interconnected system:
Children acquire language systems naturally.
Comprehension involves active listening, prediction, analysis, and inference.
Structured representations and cognitive mechanisms are essential.
Learning includes insights gained from studying language use.
Quote: "Discovery is the ability to be puzzled by simple things"
Awareness of automatic processes in speaking.
Noam Chomsky's perspective on the simplicity of speaking despite its complexity.
Language production includes multiple levels:
Precise motor control necessary.
Progression: Sounds → Words → Sentences → Discourse and dialogue.
Initiation in speaking: Begins with an idea or intention.
Planning starts at the highest intention level before motor control.
Language production remains lesser-studied.
Challenges in conducting research on sentence production versus understanding.
Observation in speech is often easier than eliciting spoken responses.
Quote: "If Language Production is so important, why does it get 1 hour on the last day?"
Reflects the current challenges faced by researchers in language production.
Naturalistic Research:
Early studies relied on observational data instead of experimental designs.
Examples include recording speech errors or conducting observational studies.
Speaker: Victoria Fromkin (1973)
Errors can provide linguistic insight into speech production mechanisms.
Examples of speech errors: Spoonerisms, Freudian slips.
e.g., "light a fire" → "fight a liar"
More examples of speech errors details:
Spoonerisms and implications for linguistic theory.
Language production follows hierarchical processes to transform thoughts into fluent speech.
Active participation of speakers involves anticipating and correcting potential errors.
Types of speech errors are indicators of computational level:
Anticipation errors: e.g., "Baris is the most beautiful city"
Perseveration errors: e.g., "That kid was escorking us"
Exchange errors: e.g., "Seymour sliced the knife with a salami"
Substitution errors: e.g., "Till your heart’s dissent"
Identification of four error types:
Anticipation
Perseveration
Exchange
Substitution
Analyzing clusters of errors can reveal various linguistic mechanisms at work.
Speaker: Gary Dell (1989)
Errors suggest language production occurs at discrete levels of representation.
Speakers plan speech level-by-level rather than blending levels.
Levelt’s Model of Language Production:
Conceptualizer (intentions)
Formulating messages with grammar and phonology
Word retrieval from lexicon
Monitoring of speech plans
Translation into articulations
Listening for errors post-speech
Study by Zenzi Griffin and Kay Bock (2000)
Initial eye fixations reflect the order of spoken subjects.
Research by Kay Bock (1986)
Grammar and sound rules shape messages.
Previous syntactic structures bias future speech output.
Demonstration of active versus passive sentence structures and their effects on speech production.
Participants repeat a sentence prime before describing an image, showing priming effects.
Findings: Previous exposure to structures impacts present speech patterns.
Evidence of individuals favoring certain syntactic structures based on prior experience.
Research by Martin Pickering and Holly Branigan (1998)
Verb repetition strengthens the priming effect on sentence structures.
Hartsuiker et al. (2006) findings on word-boost effects in speech production.
Comparison of long-term structural changes versus shorter-term response patterns in speech production.
Situations where speakers know a word's meaning but can't access its phonology.
In gendered languages, individuals still guess gender accurately even when phonological recall fails.
Studies by Gary Dell investigating how inner monitoring influences error detection.
Historical context from John B. Watson's experiments establishing the notion of inner speech.
Investigating similarity in error detection between verbal and non-verbal tasks.
Research indicates increased errors in tongue-twisters when attempting similar onset words.
Studies showing that inner speech functionality impacts outer speech errors.
Findings that articulatory movements mirror inner speech patterns regardless of articulation.
Articulatory errors can manifest during inner speech, highlighting conceptual connections in speech production.
Evidence that physical articulatory errors arise from cognitive processes and planning inefficiencies.
Slevc and Ferreira (2006) investigate sensitivity to semantic vs. phonological conflicts during speech.
Overview of the Stop-Signal Task: investigating participants' ability to halt speech under certain conditions.
Results demonstrate stronger responsiveness to phonological conflicts over semantic discrepancies.
Summary findings suggest heightened sensitivity to phonological over semantic errors.
Clarification that internal strategies focus on semantic errors while external monitoring deals with phonological output.
Revision of Levelt’s model emphasizes steps in message formulation until articulation.
Language entangles various cognitive processes; successful production demands navigating those processes.
Summary of key concepts regarding language production principles and error handling.
Highlighting importance of visual orientation, past performance influences, and internal vs. external monitoring.
