Two-component theory of the suffix effect: contrary findings
1Department of Psychology, Rice University, Houston, Texas 77251-1892, USA.
The suffix effect, a memory phenomenon, is re-examined. New research suggests the entire effect stems from grouping the suffix with list items, challenging prior two-component theories.
Area of Science:
- Cognitive Psychology
- Memory Research
Background:
- The suffix effect is a known memory phenomenon.
- It is theorized to have two components: a structural terminal component and a preterminal component.
Purpose of the Study:
- To test the validity of the two-component theory of the suffix effect.
- To investigate the underlying mechanisms of the suffix effect.
Main Methods:
- Conducted a series of 8 experiments.
- Attempted to replicate previously cited findings supporting the two-component theory.
Main Results:
- Failed to replicate key findings supporting the two-component theory.
- Evidence suggests the suffix effect is attributable to item grouping.
Conclusions:
- The traditional two-component theory of the suffix effect lacks empirical support.
- The suffix effect can be explained by the grouping of the suffix with list items.
