I think the correct answer would be the second option. Memory and attention are the two key determinants for human cognitive development in the information-processing theory of learning. It is a theory that focuses on the idea that a person manipulate an information, monitor and strategize about the information. Also, the theory states that the capacity for processing information is gradually developed. And rather than merely responding to certain stimuli, humans would tend to process first the information they had received. This theory sees the mind like a computer which is capable of processing information from the surroundings.
