    Short-term visual memory (STVM) and long-term visual memory (LTVM) components dissociate based on presentation processing time. STVM depends on display duration, while LTVM is less affected by presentation or poststimulus time.

    Area of Science:

    • Cognitive Psychology
    • Neuroscience
    • Visual Perception

    Background:

    • Visual memory comprises short-term (STVM) and long-term (LTVM) components.
    • Understanding the relationship between memory components and processing time is crucial for cognitive models.

    Purpose of the Study:

    • To investigate the differential effects of presentation processing time on STVM and LTVM.
    • To examine how display time and retention intervals influence visual memory components.

    Main Methods:

    • Three experiments measured recognition of novel visual patterns.
    • Visual memory components were isolated using short, unfilled retention intervals (STVM) or interference (LTVM).
    • Display time and poststimulus processing time were systematically varied.

    Main Results:

    • STVM increased rapidly with display time (60-200 msec).
    • LTVM showed slow, erratic increases with display time (60 msec - 2.6 sec).
    • Extended poststimulus processing time (400 msec - 2.7 sec) did not enhance LTVM.

    Conclusions:

    • Results challenge single-trace and serial models of visual memory.
    • Findings suggest distinct mechanisms for STVM and LTVM.
    • The distinction between maintenance and elaboration explains visualization without memorization.
