Working Memory Abilities

Satisfactory Essays

The purpose of this article is to find out if there is any correlation or causation effect between playing competitive sports and the development of Working Memory (WM). In order to achieve the purpose of this research, researchers studied various types of students and categorized them according to the sports they play, or not play. Researchers measure the Working Memory Capacity (WMC) of subjects using a software called Automated Operation Span (AOSPAN), which has been proven to be a good measure of WMC.

In the study presented in this article, the population is athletes, sample is 106 student athletes competing in various sports, and unit is a student athlete in an Athletics department at an American university. Having obtained this sample, …show more content…

The response variable for this study is the AOSPAN test scores, which was used to measure the WMC task capacity of participants.
A possible type of bias that lead to the problem listed in point 2 of the explanation in the article regarding WMC being unaffected by mTBI is undercoverage bias. It was mentioned that the subjects were volunteers and certain significant group of the population may not have volunteered to participate in the study. Those group of the population would then be overlooked by this study.

There were certain limitations in this study as listed in the article. Firstly, the athletes have their own choice in choosing whether to participate in the study or not. This could result in response bias and a large difference in the number of male and female participation. However, this has no significant effect on the research since effect of concussion in female is not immediately observed. Secondly, sensitive questions that could be factors affecting WMC were not obtained from the participants resulting in undercoverage bias, while those factors could very well have a significant impact on the results of the study. These lurking variables were learning disabilities, street drug or alcohol abuse, or diagnosed psychiatric disorders. Not measuring these lurking variables could result in confounding response. Thirdly, people may not report the full
