Final answer:
Working on a typewriter and then finding it easier to process words on a computer is an example of positive transfer, where skills from one task enhance performance in another.
Step-by-step explanation:
The situation you described where working on a typewriter makes it easier for you to later do word processing on a computer would best be termed positive transfer. Positive transfer occurs when learning in one context or with one set of tools enhances the ability to perform in another context or with a different set of tools. In this case, the skills learned while using the typewriter, such as keyboard layout familiarity and typing technique, are aiding your performance on a computer.
