Settee shourie biography definition psychology

What is psychology? Why do people say the things that they say and do the things that they do? Why is your toddler so endlessly entertained by peek-a-boo? Why did that other driver cut you off so aggressively? Why did your coworker lie to you about the progress he made on the project? Why did that customer leave such a huge tip on their tiny food bill?

Most of us puzzle over the causes and explanations of the things that we see other people do and the things that we find ourselves doing. Psychology is the systematic, orderly pursuit of answers to questions about the causes and drivers of human and animal behavior.

As we will see in this article, the causes of human behavior can be found on several different levels: biology, the environment, mental processes, social structures, and more. We will review these levels of explanation, as well as others, and we will briefly go over the early history of psychology as a systematic, evidence-based science. Although this definition is simple, it covers a lot.

Psychology studies the mental processes implicated in mental illness and the mental processes responsible for normal functioning. Psychology studies sensation, for example in finding the smallest detectable difference between two colors. Psychology also studies perception , for example explaining how optical and other sensory illusions are created.

Psychology studies memory, motivation , learning, and cognition. Psychology studies social processes, for example by explaining how complex decisions can be influenced by groups. Psychology covers developmental processes, studying how thinking and behavior change throughout the life cycle.
