Abstract We've all heard that "practice makes perfect," but what is the best way to practice? For example, does "mental practice" do any good? You'll need at least 9 volunteers for this project. Pick a well-defined sports activity, with a measurable outcome, such as shooting basketball free-throws (measure number of shots taken and number of shots made), or balancing on one foot on a slightly raised beam (measure how long you can do it; if it's too easy, try closing your eyes). Test all volunteers and record their performance. Assign one group to physically practice the activity daily for a specified amount of time; assign a second group to mentally practice the activity daily for the same amount of time; assign a third group to refrain from practicing the activity. Test performance of all volunteers again both 1 and 2 weeks later. Another idea: does it make a difference if your practice time is done all at once (e.g., one 5-minute session) or spread out during the day (e.g. five 1-minute sessions)?

Psychologist Why people take certain actions can often feel like a mystery. Psychologists help solve these mysteries by investigating the physical, cognitive, emotional, or social aspects of human behavior and the human mind. Some psychologists also apply these findings in order to design better products or to help people change their behaviors. |

Industrial Engineer You’ve probably heard the expression “build a better mousetrap.” Industrial engineers are the people who figure out how to do things better. They find ways that are smarter, faster, safer, and easier, so that companies become more efficient, productive, and profitable, and employees have work environments that are safer and more rewarding. You might think from their name that industrial engineers just work for big manufacturing companies, but they are employed in a wide range of industries, including the service, entertainment, shipping, and healthcare fields. For example, nobody likes to wait in a long line to get on a roller coaster ride, or to get admitted to the hospital. Industrial engineers tell companies how to shorten these processes. They try to make life and products better—finding ways to do more with less is their motto. | |
