[Investigating phonological planning processes in speech production through a speech-error induction technique]

Area of Science:

• Psycholinguistics
• Cognitive Science
• Speech Production Research

Context:

• Investigating phonological planning, a key mechanism in speech production and memory.
• Building upon previous research using speech-error induction with auditory word distractors.
• Addressing the potential for lexical intrusions in prior speech error studies.

Purpose:

• To validate the temporal distance and edge principles in phonological planning.
• To differentiate phonological planning mechanisms from lexical/semantic influences.
• To confirm findings using nonword distractors to isolate phonological processes.

Summary:

• Replicated previous findings on within-word adjacent mora exchanges and serial position effects using nonword distractors.
• Demonstrated that temporal distance and edge principles organize phonological planning.
• Confirmed that speech errors reflect underlying phonological organization, independent of lexical factors.

Impact:

• Provides robust evidence for the temporal distance and edge principles in phonological planning.
• Clarifies the role of phonological representations separate from lexical and semantic information.
• Enhances understanding of the cognitive mechanisms underlying fluent speech production.
