Final answer:
Ethics training is most effective when it elicits a positive immediate response, demonstrates learning outcomes, improves job performance, and yields positive results for organizations.
Step-by-step explanation:
According to a 2003 study by Arthur, Bennett, Edens, and Bell, ethics training is most effective when it is evaluated based on four types of measurements: immediate employee response, testing at the end of training, behavioral measurements of job activities, and productivity and profits.
The study examined various forms of training, including self-instruction, lecture and discussion, and computer-assisted training.
Therefore, ethics training is most effective when it elicits a positive immediate response, demonstrates learning outcomes, improves job performance, and yields positive results for organizations.
