Summary
This special issue explores lexical access in speech production, dividing it into lexical selection and phonological encoding. Research integrates speech errors, aphasiology, and reaction time studies to understand word retrieval.
Area of Science:
- Psycholinguistics
- Cognitive Science
- Speech Production Research
Background:
- The study of lexical access in speech production has been significantly advanced by analyzing speech errors, dysfluencies, hesitations, aphasiology, and reaction time research over the past 25 years.
- Current theoretical models propose a two-stage process for accessing words during speech production: lexical selection and phonological encoding.
Purpose of the Study:
- This special issue aims to present current research on lexical access in speech production.
- It focuses on the distinct subprocesses of lexical selection and phonological encoding, and their interaction.
Main Methods:
- The issue draws upon analyses of speech errors, dysfluencies, and hesitations.
- It incorporates findings from aphasiology and reaction time research paradigms.
- Theoretical frameworks are developed and discussed.
Main Results:
- The emerging theoretical framework partitions word access into lexical selection (retrieving a lemma) and phonological encoding (computing a phonetic program).
- The special issue is organized into sections addressing lexical selection, phonological encoding, and their interaction.
Conclusions:
- The research presented highlights the distinct yet interconnected nature of lexical selection and phonological encoding in speech production.
- Ongoing research continues to address core issues within these domains, with a particular focus on the controversial interaction between phonological encoding and lexical selection.
