Word frequency and list composition effects in associative recognition and recall

Area of Science:

• Cognitive Psychology
• Memory Research

Background:

• Word frequency is a known factor influencing memory performance.
• Previous research suggests high-frequency (HF) words are recalled better than low-frequency (LF) words.

Purpose of the Study:

• To investigate the effects of list composition and word frequency on different memory tasks: cued recall, associative recognition, and item recognition.
• To compare memory performance in pure-frequency lists versus mixed-frequency lists.

Main Methods:

• Three experiments were conducted manipulating list composition (pure vs. mixed) and word frequency (HF vs. LF).
• Participants completed cued recall, associative recognition, and item recognition tasks.

Main Results:

• In pure lists, HF words showed better cued recall and associative recognition, whereas LF words were better for item recognition.
• In mixed lists, the HF advantage for cued recall diminished, but frequency effects persisted in item and associative recognition.
• These findings challenge attention-based and co-rehearsal explanations for word frequency effects.

Conclusions:

• Memory recall and recognition are differentially affected by word frequency and list composition.
• Recognition memory appears less sensitive to list composition effects compared to recall memory.
• The results align with list strength theories, suggesting distinct mechanisms for recall and recognition processes.
