Our memory can be compared to a library where memories are stored in a coding system. It is the mechanism that involves the acquisition, storage, and retrieval of information. Attention, on the other hand, is the ability to coordinate multiple processes, prepare and handle the flow of information in a special way. However, attention tends to decrease in situations with high environmental stimuli and as we age.
Difficulty in concentration refers to the inability to focus on multiple tasks at the same time, such as being unable to fully engage in reading or experiencing academic difficulties.
