Based on the study, which was spearheaded by researchers from Abo Akademi University, the relevance of these strategies was highlighted by the controls who weren't given any strategy advice, yet were able to generate strategies that were connected to better working memory task performance at post-test.
The study's results imply that a substantial part of working memory training effects is due to the rapid development of certain task-specific strategies while training instead of any improvement in working memory capacity as was previously speculated.
The researchers believe that this is the reason why the significant effects of typical working memory training are restricted to the trained task and its associated untrained variants. While there are several commercial working memory training programs on hand, their training effects do not significantly generalize beyond the tasks that are like the trained ones.

For the study, which was published in the peer-reviewed open access journal Scientific Reports, the researchers observed 116 Finnish adults who were randomized into three groups. The participants in the first group were given a short strategy instruction and they trained a working memory updating task for 30 minutes.
Participants in the second group underwent the same computerized training session without receiving any strategy advice. Meanwhile, the third group only performed the pre- and post-test.
The self-generated strategies were then analyzed through questionnaires that were accomplished at the post-test.
