摘要
Short-term memory in vision is typically thought to divide into at least two memory stores: a short, fragile, high-capacity store known as iconic memory, and a longer, durable, capacity-limited store known as visual working memory (VWM). This paper argues that iconic memory stores icons, i.e., image-like perceptual representations. The iconicity of iconic memory has significant consequences for understanding consciousness, nonconceptual content, and the perception-cognition border. Steven Gross and Jonathan Flombaum have recently challenged the division between iconic memory and VWM by arguing against the idea of capacity limits in favor of a flexible resource-based model of short-term memory. I argue that, while VWM capacity is probably governed by flexible resources rather than a sharp limit, the two memory stores should still be distinguished by their representational formats. Iconic memory stores icons, while VWM stores discursive (i.e., language-like) representations. I conclude by arguing that this format-based distinction between memory stores entails that prominent views about consciousness and the perception-cognition border will likely have to be revised.
