Does silent reading involve articulation? Evidence from tongue twisters

Area of Science:

• Cognitive Psychology
• Linguistics
• Speech Science

Background:

• Silent reading is often assumed to be purely visual.
• The role of subvocal articulation in silent reading is not fully understood.
• Previous research has explored the impact of overt speech on reading.

Purpose of the Study:

• To investigate the interfering effect of subvocal articulation on silent reading.
• To compare reading times for tongue twisters versus control sentences.
• To explore the relationship between articulatory errors and reading speed.

Main Methods:

• College students repeatedly read tongue-twister and control sentences, silently and aloud.
• A novel technique measured sentence repetition time.
• Oral repetitions were analyzed for articulatory errors.

Main Results:

• Tongue twisters significantly increased reading time in both silent and oral conditions compared to controls.
• A high correlation was found between oral reading errors and oral reading time.
• Silent reading of tongue twisters also showed increased reading times.

Conclusions:

• Subvocal articulation interferes with silent reading.
• Articulatory disturbances, even when not overt, slow down silent reading.
• The findings suggest a link between speech production mechanisms and reading comprehension.
