found: Colman, A.M. A dictionary of psychology, 2001(learning curve -- A mathematical expression of the changes in behaviour occurring as a function of practice, usually represented by a graph showing a measure of performance on the vertical axis and amount of learning, represented by trials or time, on the horizontal axis; also called a practice curve)

found: Corsini, R.J. The dictionary of psychology, 1999(learning curve -- A graph representation that reflects the course of learning; a measure of performance (for example, gains, errors) represented along the vertical axis; horizontal axis plots trials or time; the learning of a group or individual may be represented by the curve)
