A 1990 study suggested two memory processes based on "remember" and "know" responses. Modern replications failed to find this crossover effect, supporting a single-process memory account instead.

Area of Science:

  • Cognitive Psychology
  • Human Memory Research

Background:

  • The "remember"/"know" distinction is a key paradigm in memory research.
  • Gardiner and Java (1990) reported a crossover interaction suggesting two distinct memory processes.

Purpose of the Study:

  • To conduct a modern replication of Gardiner and Java's (1990) study.
  • To investigate the replicability of the crossover interaction in memory retrieval.

Main Methods:

  • Three experiments (N=large) attempted to replicate the original crossover effect.
  • A fourth experiment used a sure-unsure paradigm to re-examine baseline findings.

Main Results:

  • The crossover interaction reported by Gardiner and Java was not replicated across three experiments.

  • Data from replication attempts were more consistent with a single-process memory model.
  • A sure-unsure paradigm replicated baseline findings but supported a single-process explanation.

    • Conclusions:

    • The original crossover effect observed by Gardiner and Java appears not to be replicable.
    • Evidence from this study supports a single-process account of memory retrieval over a dual-process account.
