This part of the Psychology 101 series of posts is about thought and reasoning – the ways we transform and manipulate mental representations to navigate our way through life. Thoughts manifest, and the power of thoughts should not be underestimated. This is why it is such a big area of interest in the field of psychology. The following post will explore the basic units of thought, such as mental images and concepts, and the way people manipulate these units to reason, solve problems and make decisions. Next we examine implicit and everyday thinking, exploring how people solve problems and make judgements outside of awareness, often relying on emotion as well as cognition.
