Answer:
Bill and Eric are both preparing to take an IQ test. Bill has already taken this test multiple times over the past several weeks, while Eric, who will be taking the test for the first time, has prepared by repeatedly doing a 'memory drill' app installed on his phone. Assuming that the IQ test scores of both Eric and Bill have been improved by their preparation efforts, Eric's score would show transfer effects while Bill's score would show practice effects.
Step-by-step explanation:
Practice effects = Experiencing one level affects behavior inn another level.
e.g effects of practice , boredom , fatigue.
Practice effects are controlled in within-subjects designs by randomizing or counterbalancing the presentation orders.
While on the other hand, carryover effects. differential/asymmetrical transfer effects usually occur when experiencing one level affects performance on the next.The effect of first level on the next level depending on what comes first.
Hence in the given scenario, Bill and Eric are both preparing to take an IQ test. Bill has already taken this test multiple times over the past several weeks, while Eric, who will be taking the test for the first time, has prepared by repeatedly doing a 'memory drill' app installed on his phone. Assuming that the IQ test scores of both Eric and Bill have been improved by their preparation efforts, Eric's score would show transfer effects while Bill's score would show practice effects.
