    Summary
    This summary is machine-generated.

    Environmental context significantly impacts temporal memory. Changes in context reduce or eliminate duration memory biases, while list discrimination improves with context changes, supporting a contextual-change hypothesis for memory.

    Area of Science:

    • Cognitive Psychology
    • Memory Research
    • Environmental Psychology

    Background:

    • Temporal memory judgments are susceptible to various internal and external factors.
    • Environmental context is a known modulator of cognitive processes, including memory.

    Purpose of the Study:

    • To investigate how environmental context changes influence temporal memory judgments.
    • To examine the effect of context on duration memory, list discrimination, and serial-position judgments.

    Main Methods:

    • Three experiments were conducted using two equal durations (D1 and D2) with items presented within each.
    • Participants made temporal judgments and later performed recognition tests including list and serial-position discrimination.
    • Environmental context was manipulated by keeping it constant, disrupting it between durations, or changing it during the second duration.

    Main Results:

    • Unchanged environmental context led to D1 being remembered as longer than D2.
    • Context disruption between durations reduced this effect; changing context during D2 eliminated it.
    • List discrimination improved only when environmental context was changed.
    • Serial-position judgments were unaffected by context manipulations.
    • Changes in internal process context also affected duration memory.

    Conclusions:

    • Environmental context plays a crucial role in shaping temporal memory judgments.
    • The findings support a contextual-change hypothesis, suggesting memory is sensitive to contextual stability.
    • Contextual changes differentially affect various aspects of memory, such as duration estimation versus item discrimination.
