List context fosters semantic processing: parallels between semantic and morphological facilitation when primes are...

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• Understanding word recognition is crucial for cognitive science.
• Priming paradigms reveal how prior exposure influences lexical decision-making.
• The role of different stimulus properties (orthographic, semantic, morphological) in priming is actively investigated.

Purpose of the Study:

• To investigate how different filler trial contexts affect priming effects.
• To determine whether early word processing is primarily form-based or semantically driven.

Main Methods:

• Forward-masked priming was used across three experiments.
• Filler trials varied in type: mixed (morphological, orthographic, semantic), identity, and semantic.
• The proportion of related prime-target pairs was held constant at 75%.

Main Results:

• Morphological priming effects were observed consistently across all filler contexts.
• Semantic priming effects were present only in identity and semantic filler contexts.
• Orthographic priming effects were absent in all tested contexts.

Conclusions:

• Early word processing appears to be attuned to semantic information rather than solely relying on form-based cues.
• The type of filler context significantly modulates the observed priming effects, particularly for semantic relationships.
