Revisiting bias effects in word-initial phonological priming

Area of Science:

• Psycholinguistics
• Cognitive Psychology
• Speech Perception

Background:

• The phonological priming paradigm is valuable for studying lexical processing.
• Concerns regarding response biases potentially distorting results have persisted since the paradigm's inception.

Purpose of the Study:

• To explore the manifestation of response biases within the phonological priming paradigm.
• To compare priming effects at different stages of a testing session using modified experimental conditions.
• To investigate if response biases influence lexical inhibition, particularly when primes and targets share initial phonemes.

Main Methods:

• Modified the standard phonological priming experiment to assess bias effects over time.
• Conducted four experiments to compare priming effects and response biases under varying conditions.
• Utilized items with shared initial phonemes (first 3 phonemes) to examine lexical inhibition.

Main Results:

• Response biases were observed even in experimental conditions previously believed to mitigate their influence.
• The study demonstrated that biases can manifest and affect outcomes in phonological priming tasks.
• Findings suggest that response biases are a persistent factor in lexical processing studies using this paradigm.

Conclusions:

• Response biases remain a significant concern in phonological priming research.
• The presence of biases in supposedly controlled conditions necessitates careful consideration in interpreting lexical processing data.
• Further research is needed to fully understand and control for response biases in priming paradigms.
