15. Take your learning a step further by testing your critical thinking skills on this scientific problem solving exercise.

____1___

Playing a musical instrument is a complicated skill that involves every major aspect of behavior and cognition. To be proficient, musicians must have honed their fine motor skills. In addition, many aspects of thinking come into play, including memory of how to play the instrument and of musical scales and time signatures, and the planning and decision making inherent in translating a piece of sheet music into sound. Equally important are the musician's motivation and emotion, which influence many aspects of a musical performance.

In this exercise you will develop a map describing how various parts of the brain enable a musician to perform a piece of music. Using the following grid, identify three lower level brain structures and three upper level structures and then describe how each structure is involved in musical performance.

You have decided to open a baby-sitting service for children from 18 months to 12 years of age. Your advertising campaign is based on your intention to provide children with intellectually stimulating activities. To design activities that will be appropriate for children of different ages, you decide to follow Piaget's stage theory of cognitive development.

Your task in this exercise is to imagine the viewpoint of children at various stages of cognitive development. For the moment, set aside what you think about the intellectual abilities of children of various ages and try to identify with the unique ways in which they experience the world. Then describe two or three intellectually stimulating activities that would be appropriate for each group.

How does an 18-month-old child experience the world?

What activities would you plan for an 18-month-old child?

How does a 5-year-old child experience the world?

What activities would you plan for a 5-year-old child?

How does an 8-year-old child experience the world?

What activities would you plan for an 8-year-old child?

How does a 12-year-old child view the world?

What activities would you plan for a 12-year-old child?

Rochelle has always felt very competitive with other people, especially her older and only sibling, Doreen. Doreen is less competitive and more motivated by the desire to perform to the best of her ability than by comparing herself with others. Rochelle has always received lower grades in school than Doreen, who receives consistently high scores. Rochelle claims this is because she intentionally selects more difficult classes and instructors than her sister. Doreen responds that she picks instructors who are challenging yet fair, while her sister picks either impossibly difficult or ridiculously easy instructors.

Rochelle has often followed in her older sister's footsteps as Doreen developed new interests. For example, Doreen recently took up the guitar. On her own initiative, she began taking lessons and diligently practicing for an hour each day. Her proud parents frequently praised her for her discipline and musical progress. Not to be outdone, Rochelle decided to start playing the guitar as well. After a week or two, however, her interest in practicing began to wane. To increase their daughter's motivation, Rochelle's parents announced that for 1 month they would reward both daughters' efforts by giving them one dollar for each hour they practiced. The additional incentive seemed effective for Rochelle, who increased practice time to nearly match Doreen's. Much to her parents' surprise, however, Doreen's interest level and practice time actually decreased when the monetary incentive was provided. At the end of the month the puzzled parents withdrew the reward for practicing. Three weeks later neither Rochelle nor Doreen seemed very interested in playing the guitar.

  1. What principles of motivation might help explain why Rochelle and Doreen differ in the level of their school performance?

  2. What principles of motivation might help explain why the monetary reward for practicing influenced Rochelle and Doreen differently?

  3. What advice would you offer to Doreen's and Rochelle's parents if they wished to renew their daughters' interest in playing the guitar?
