    Priming effects on color perception depend on memory recall. Short delays enhance category distinctions, while longer delays blur them, indicating shifts from physical to conceptual color coding.

    Area of Science:

    • Cognitive Psychology
    • Visual Perception
    • Color Science

    Background:

    • The interplay between physical and conceptual representations of color is crucial for visual processing.
    • Understanding how memory limitations affect color categorization is key to visual cognition research.

    Purpose of the Study:

    • To investigate how the decreasing availability of physical color codes influences the efficacy of conceptual color codes.
    • To examine the temporal dynamics of priming effects in color perception.

    Main Methods:

    • Participants judged the physical identity of color chips.
    • A prototype color chip was presented as a prime before test pairs.
    • Varying delay intervals (0s, 1s, 2s) were introduced between the prime and test pairs.
    • Response times and accuracy were measured for 'good' and 'poor' category members.

    Main Results:

    • Under 0s and 1s delays, priming facilitated responses to good category members and inhibited responses to poor members.
    • After a 2s delay, priming facilitated responses to both good and poor category members.
    • This suggests a shift in processing from physical to conceptual color representation.

    Conclusions:

    • Priming effects are initially mediated by the physical color code.
    • As physical code availability decreases (longer delays), conceptual representations become dominant.
    • This highlights the dynamic nature of color memory and categorization.
