Textbook Problem

Psychologists interested in learning theory study **learning curves**, A learning curve is the graph of a function *P*(*t*), the performance of someone learning a skill as a function of the training time *t*. The derivative *dP*/*dt* represents the rate at which performance improves.

- (a) When do you think
*P*increases most rapidly? What happens to*dP*/*dt*as*t*increases? Explain. - (b) If
*M*is the maximum level of performance of which the learner is capable, explain why the differential equation

is a reasonable model for learning.

- (c) Make a rough sketch of a possible solution of this differential equation.

(a)

To determine

**To find:** Time at which *P* increases most rapidly and to study the behavior of
*t* increases.

Explanation

At the beginning *P* increases most rapidly, it is reasonable to assume that one beginner learns more at starting time. Initially

(b)

To determine

**To explain:** The differential equation

(c)

To determine

**To sketch:** The possible solution of the differential equation.
