From the word ‘psychology’, ‘psycho’ refers to ‘psyche’ which means ‘mind’, ‘soul’, ‘breath’ and ‘spirit’; and ‘logy’ refers to ‘study of’ or ‘research’ (Online Etymology Dictionary, 2001). And according to Andrew (2009), psychology defined as ‘treats of the soul’. And I define psychology as knowledge which enables us to interpret a person’s mood and thought by observing his or her motion. For example, when a person tells lies, he or she may have petty actions (e.g. fiddling with hair, scratching their nose or continuously changing his sitting posture). Also, I think psychology is a study that allows us to understand and predict a person’s action by reviewing his or her family history, childhood nightmare or big events in his life. For instance, a boy loved his girlfriend a lot, unfortunately his girlfriend died, and some of the organs of that girl were transplanted to some of the patients. Since the boy didn’t want the others to possess her girlfriends’ organs or tissues, therefore he killed people who received the organs, and became a serial killer. And by applying skills learned in psychology, by revising the events happening around the boy, the reason of killing and the boy’s next target can be deduced.

In the video, eight people are divided into 2 teams (the white team and the black team) to play basketball. And students were asked to count the number of passes made by the white team. At that time most of the
