Is scanning in probed order recall articulatory?

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Memory

Background:

• Serial recall theories offer insights into short-term memory for ordered sequences.
• The mechanism of 'scanning' during cued recall remains debated, particularly its potential link to articulation.

Purpose of the Study:

• To test whether covert serial recall ('scanning') in short-term memory tasks is articulatory.
• To investigate the influence of word syllabic length on recall latency and accuracy.

Main Methods:

• Two experiments manipulated the syllabic length of words preceding and following target positions in sequences.
• Recall latency and accuracy were measured to assess memory performance.

Main Results:

• Recall latency varied with target position but was not affected by the word length of preceding items.
• Recall accuracy was influenced by the word length of all list items, consistent with distinctiveness assumptions.

Conclusions:

• Evidence does not support an articulatory basis for memory scanning in short-term recall tasks.
• If scanning occurs, it is unlikely to involve covert or overt articulation.
