A common neural axis links image distinctiveness and memorability

High H-ability is linked to low FA-ability through a shared neural axis, with image distinctiveness predicting the flipped relationship in both behavior and neural activity.

• Why it matters: Stimulus-specific memorability is a key predictor of memory, but prior findings suggest hit-ability and false alarm-ability may be dissociable, leaving the underlying mechanism unclear.
• What they did: The authors combine neural measures with computational modeling to test whether the neural signature for high H-ability matches that for low FA-ability, and examine how image distinctiveness relates to the H-ability/FA-ability relationship.
• The result: They find an inverse relationship between H-ability and FA-ability along a common factor, and show that image distinctiveness predicts the flipped relationship in both behavioral performance and neural activity.
