Mechanisms of word concreteness effects in explicit memory: Does context availability play a role?

Area of Science:

• Cognitive Psychology
• Neuroscience
• Linguistics

Background:

• Concrete words are recalled better than abstract words, potentially due to context availability.
• Existing explanations for this concrete-word advantage in recall do not extend to recognition memory.
• The role of context availability in recognition memory for word concreteness is under-explored.

Purpose of the Study:

• To investigate if context availability explains the concrete-word advantage in both free recall and item recognition.
• To examine how different levels of sentence constraint (low vs. high) influence recall and recognition of concrete and abstract words.
• To determine if context availability can account for concreteness effects in explicit memory.

Main Methods:

• Two experiments were conducted, one for free recall (Experiment 1) and one for item recognition (Experiment 2).
• Target words were presented in isolation, within low-constraint sentences, or within high-constraint sentences at study.
• The effects of word concreteness and sentence semantic constraint on memory performance were analyzed.

Main Results:

• Concrete words showed an advantage in both free recall and item recognition, consistent with prior research.
• Low-constraint sentence contexts impaired recall but improved recognition compared to isolated words.
• High-constraint sentence contexts impaired both recall and recognition compared to low-constraint contexts.
• The concreteness effect persisted regardless of sentence context, word frequency, or semantic constraint level.

Conclusions:

• Differences in context availability do not explain the concrete-word advantage in either recall or recognition memory.
• The findings suggest that other factors beyond context availability underlie the memory benefits of concrete words.
• The study highlights the complex interplay between word properties, context, and memory processes in explicit memory tasks.
