Recollection in the context of recognition memory: When the probe is willing but the mind is weak Marty Niewiadomski Steve Joordens Bill Hockley U of Toronto at Scarborough Wilfrid Laurier University

Mirror Effect Within a yes/no recognition memory context present low and high frequency items Low frequency words show a memory advantage: lower false alarms and higher hits Low freq High freq new old FAs HITS LOW FREQ HIGH FREQ

Mirror Effect Several accounts of the mirror effect, eg. Glanzer & Adams (1985); Hintzman & Curran (1997); Hirshman & Arndt (1997); Reder et al. (2000); Joordens & Hockley (2000) Joordens & Hockley (2000) - Hit portion of the mirror effect is due to a combination of familiarity and recollection Low freq High freq familiarity recollection new old

Environmental support
Recognition = mirror effect Partial-item recognition = no mirror effect Partial-item recognition 2 = no mirror effect Cued recall Free recall
15
Conclusions.....so far Given the assumption that the old portion of the effect is primarily due to recollection, environmental support appears to affect not just memory retrieval in general, but more specifically the recollection component
16
Question Is there anything else beyond encoding and environmental support that influences recollection? Well, Yes (if not, I probably wouldn’t ask the question)

22
In Conclusion Recollection begets recollection
Failure of successful recollection on some trials appears to prevent the use of recollection for the entire test – even when good encoding and environmental support are present Possibly the best all around strategy – one size (read: strategy) fits all
