Modelling effects of object naming on long-term object recognition memory

摘要: Lupyan (2008) demonstrated that overtly naming objects leads to impaired long-term recognition memory compared to objects rated for preference (naming effect). Critically, this effect was reflected in a reduction in hit rates for named objects with no differences in false alarm rates. Participants failed to recognize previously named objects but were not biased to falsely recognize lures matched to named objects. Lupyan proposed a representational shift account of this naming effect whereby overtly naming an object activates top-down information of the object’s category that then augments the bottom-up object representation. This top-down categorical information thus distorts the representation for the named object creating a mismatch between the memory representation of the object and the perceptual representation of the object when it is presented again later during a memory test. This mismatch leads to a lower …
