Modality, concreteness, and set-size effects in a free reconstruction of order task

Area of Science:

• Cognitive Psychology
• Human Memory
• Experimental Psychology

Background:

• Long-term free reconstruction of order tasks are often assumed to isolate memory for item order.
• Factors like presentation modality, item concreteness, and list set size may influence performance in these tasks.
• The extent to which these factors interfere with pure order memory is not fully understood.

Purpose of the Study:

• To investigate whether informing participants about presented items removes modality, concreteness, and set size effects in long-term order memory.
• To determine if the reconstruction of order task provides a functionally pure measure of order memory.

Main Methods:

• Experiment 1: Examined modality effects (auditory vs. visual presentation).
• Experiment 2: Assessed effects of item concreteness (concrete vs. abstract items).
• Experiment 3: Investigated set size effects (repeated vs. unique item sets).
• In all experiments, participants received the to-be-remembered items at test.

Main Results:

• A significant modality effect was observed: auditory presentation enhanced memory for the final item.
• Order memory was superior for concrete items compared to abstract items.
• Order memory was better when a consistent set of six items was used across trials.

Conclusions:

• Presentation modality, item concreteness, and set size continue to affect order memory even when participants are informed about the items.
• The reconstruction of order task is not a functionally pure measure of order memory, as demonstrated by persistent external influences.
• These findings challenge the assumption that order reconstruction tasks exclusively measure memory for sequence.
