Investigates how reward associations influence recognition memory for abstract visual stimuli, suggesting strong implications for memory processes.

The research aims to explore how motivation affects recognition memory for abstract stimuli, even when these stimuli lack meaning.
Conducted two experiments with 48 participants using event-related brain potentials (ERPs).
Participants learned associations between meaningless consonant strings and monetary outcomes (gain, loss, or zero).
Examined the effects of character combinations and font types on recognition memory using an old/new task.
Manipulated memory status and motivational relevance during recognition testing.
Observed enhanced P300/LPC amplitudes for gain-old stimuli, indicating stronger recollection when motivation is present.
Found higher recognition accuracy for gain-old compared to novel stimuli.
Noted a shift from motivation-driven memory enhancement to familiarity-based processes over time.

Grassi et al. (2026) studied this question.
