Hussein is concerned because he cannot remember events from before he was about 4 years old. what is the most likely cause for this infantile amnesia? his memories began to be organized differently after he turned 3 or 4. his maturing cortex allowed him to gain a sense of self he didn't have before he was 4. his maturing cortex increased his long-term storage after age 4. all of these things contribute to infantile amnesia.

The correct answer is "all these things contribute to childhood amnesia." This is because when we are born, our brain is still forming, so the information we receive cannot be organized correctly, we also do not have concepts or memories that allow us to understand what we perceive, that is why we can not understand it. As we grow our cerebral cortex matures and we acquire memories and concepts that allow us to organize what we see, and in this way form memories.

I hope my answer can help you.
