Test context affects recollection and familiarity ratings: implications for measuring recognition experiences

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Memory Research

Background:

• The binary remember/know task forces participants to choose between recollection and familiarity, potentially oversimplifying subjective recognition experiences.
• Previous research indicates that various factors can produce dissociative effects on these binary remember/know judgments.
• In contrast, independent recollection and familiarity ratings often show parallel effects, hinting that binary judgments might be artifactual.

Purpose of the Study:

• To investigate whether the test-list context effect, previously observed with binary remember/know judgments, also manifests with independent recollection and familiarity ratings.
• To explore the role of response bias in mediating the effects of test-list context on recognition memory judgments.
• To advocate for the use of independent ratings over binary judgments for a more accurate assessment of recognition memory components.

Main Methods:

• Participants were asked to make independent ratings of recollection and familiarity for studied items.
• A test-list context manipulation was employed, varying the memorability of concurrently presented items.
• Response bias was analyzed to understand its influence on the observed effects.

Main Results:

• A parallel test-list context effect was observed for independent recollection and familiarity ratings, mirroring findings from binary judgments.
• This effect was found to be induced by a shift in response bias.
• The results suggest that binary judgments may not fully capture the nuances of subjective recognition experiences.

Conclusions:

• Independent recollection and familiarity ratings are preferable to binary judgments as they allow for the direct reporting of the co-occurrence of these recognition components.
• The findings have implications for how self-reported recognition experiences are measured and for theoretical accounts of recognition memory.
• The study supports the idea that binary judgments can lead to artificial dissociations in memory research.
