Limiting lexical activation limits perceptual priming in masked word identification

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• Perceptual priming is influenced by prior word exposure.
• The role of lexical processing in priming requires further investigation.

Purpose of the Study:

• To test if perceptual priming depends on prior lexical processing.
• To determine the contribution of auditory input from reading aloud to priming effects.

Main Methods:

• Four experiments were conducted using tasks like first-letter naming, word fragment completion, and masked word identification.
• Word frequency and auditory input manipulations were employed.
• Participants performed tasks involving word recognition and frequency judgments.

Main Results:

• First-letter naming reduced priming compared to whole-word reading.
• Masked word identification was enhanced by prior word processing, especially for low-frequency words read aloud.
• Replication of findings ruled out cross-modal input as the source of effects.

Conclusions:

• Activation of a lexical unit is a critical determinant of perceptual priming.
• Lexical processing, not just visual input, significantly impacts word priming.
• Auditory feedback from reading aloud plays a role in frequency-dependent priming effects.
