Consequently, the use of metal machine parts was kept to a minimum. Hand methods of production were very laborious and costly and precision was difficult to achieve. [30] [31] With their inherent precision, machine tools enabled the economical production of interchangeable parts. [28] [29] [32] Examples of machine tools include: [28] [29]
An example of a negative transfer is if it takes longer for a typist to adjust to a randomly assigned letter of the keyboard compared to a new typist. Retention: the performance level of a particular skill after a period of no use. [18] The type of task can have an effect on how well the motor skill is retained after a period of non-use:
