According to the study on memory interference conducted by Mcgeoch and Mcdonald (1931), as interference "decreases", retention "improves".

In the year 1931, McGeoch and McDonald directed a trial to learn about interference in LTM. All members learned a rundown of ten adjectives perfectly. Members were then partitioned into gatherings to do diverse exercises previously being requested to review the first ten objectives. A few members that burned through 10 minutes resting had the most elevated review of 4.50 descriptive words by and large followed by 3.68 for the individuals who learned 3-digit numbers, 2.58 for drivel syllables gathering, and 2.17 for disconnected adjectives group and so on. This recommends retroactive interference occurs in light of the fact that it demonstrates that the later material influenced the review of the first material, and the more comparable the later material, the more prominent the interference and the more elevated amount of forgetting.
