Delayed monochromatic hue matches indicate characteristics of visual memory.

摘要: Short-term memory for 16 monochromatic hues from 425 to 640 nm was measured after six delays .1 24.3 sec by means of an iterative, momentary stimulus-matching technique. Small shifts were revealed in the remembered hue produced certain wavelengths at some delays. These did not follow trends consistent with a storage dependent on sensory pathway characteristics, perceptually unique hues, or semantic encoding but may reflect entropic effects that is remarkably unbiased. By indicating discriminability memory, standard deviations delayed matches reveal other characteristics what stored: Their smooth, exponential growth questions existence "levels" and permits estimating half-life memory; their continued resemblance discrimination function simultaneously perceived suggests stored activity; closely resembled response color. The results also indicate how successive comparisons be corrected applied color work.
