 Psychologists at Johannes Gutenberg University Mainz (JGU) discovered that although depressed individuals perceive slow time passage, their estimates are just as accurate as normal individuals when asked to judge the duration of a specific time interval, such as two seconds or two minutes.People with depression often tend to experience the world differently from others, report changes in appetite, and sometimes feel that time drags on.In a study, mathematical psychologist Diana Kornbrot of the University of Hertfordshire and her colleagues applied the Beck Depression Inventory (BDI) to gauge the mood of 46 participants.
