Imagine that you were a participant in Sperling's classic study on iconic memory. Why aren't you able to identify all the letters presented on the screen?

I was unable to identify all the letters presented on the screen because they are presented too briefly.

Explanation:

I participated in the classic study conducted regarding the iconic memory in Sperling. During the study, some letters were displayed on the screen. But I was not able to identify all the letters present on the screen because they are presented too briefly.

It takes some time to identify the letters displayed on the screen, as the letter information should be transferred from sensory memory to short-term memory.

Iconic memory is a visual memory in which people remember or memorize something by seeing the visual information very briefly.
