Summary
Speakers can revise speech plans when correcting errors, rather than always starting over. This speech repair process involves revising existing plans, not just replanning from scratch.
Area of Science:
- Psycholinguistics
- Cognitive Science
- Speech Production
Background:
- Understanding speech error repair is crucial for cognitive and psycholinguistic research.
- Investigating whether speakers revise speech plans or restart anew when correcting errors.
Purpose of the Study:
- To determine if speech error repair involves revising an existing plan or starting from scratch.
- To differentiate between the 'restart' and 'revision' hypotheses of speech production.
Main Methods:
- Two experiments were conducted comparing speech production under different planning conditions.
- Participants produced target utterances following prime utterances with single-word differences (addition or deletion).
- Experiment 1 involved planning and producing a prime then target; Experiment 2 involved planning a prime but only producing the target.
Main Results:
- No significant difference in production time between additions and deletions in Experiment 1.
- Additions took significantly longer than deletions in Experiment 2.
- Results support the revision hypothesis over the restart hypothesis.
Conclusions:
- Speakers can repair inappropriately specified utterances by revising their speech plans.
- Speech production planning is flexible, allowing for modifications rather than complete restarts.
- Findings contribute to understanding the cognitive mechanisms underlying fluent speech.
