Question restatement: The prompt asks which memory storage explains why you still see the sparkler’s afterglow as you move it back and forth. Answer options are:
- semantic (meaning)
- structural (visual)
- acoustic (phonemic)
- Sensory/iconic
- sensory/echoic

Analysis of each option:
- semantic (meaning): This refers to memory for the meaning of information, not its sensory appearance or persistence. It explains knowledge like concepts and definitions, not how long a visual image persists after the stimulus is gone. Therefore, this option misapplies a high-level memory system to a perceptual persistence phenomenon.
- structural (visual): While this phrasing seems to hint at a visual memory aspect, standard terminology distinguishes iconic memory as the brief visual sensory store, not a separate structural visual memory. The wording is not the conventional label researchers use for this phenomenon, making it an imprecise choice.
- acoustic (phonemic): This concerns the sound structure of language, i.e., phonemic memory. It is unrelated to visual afterglow or persistence of a visual stimulus, so this option does not fit the scenario.
- Sensory/iconic: This is the conventional label for visual sensory memory, the brief persistence of visual information after the stimulus is gone. The iconic store explains why the glow of a sparkler can be seen momentarily as it moves, due to persistence of the visual image in memory.
- sensory/echoic: This term denotes auditory sensory memory, the brief retention of sounds. Since the sparkler’s afterglow is a visual phenomenon, echoic/sensory memory would not account for it.

In summary, the correct concept here is iconic memory (a type of sensory memory for visual information), because it describes the brief continuation of a visual image after the stimulus has moved or disappeared. The other options either describe memory for meaning, incorrectly labeled visual structures, or auditory memory, which do not explain the visual afterglow effect.
