Hello.
I'm not a psychology student but interested in it so as per your question this qualifies me to share with you a psychology book that I think you might have heard about but still it's so good that i would like to suggest it anyway. It's by Daniel kahneman, a noble lauriete and psychology professor. Its name's THINKING FAST AND SLOW.
It talks about the two systems of the brain which have the capacity of thinking, processing and making decisions at their own pace and in doing so how their pace affects our decision making.
