Question

what is missing: memory is taking stuff in, _______, then bringing it back out again? processing it encoding it storing it

Explanation:

In the memory process, the typical stages are encoding (taking stuff in), then storing the information, and finally retrieval (bringing it back out). So the missing step between taking in and bringing out is storing it. "Processing it" is not a standard stage in the basic memory model, and "encoding it" is the first step (taking stuff in), so the correct option is "storing it".

Answer:

storing it
