The Effect of Age, Sleep Duration, Learning Duration, and Coffee Intake on Short-Term Memory

Abstract

In the reality of life, learning requires a process of remembering. In the process of teaching and learning, memory is crucial. Sleep deprivation affects the process of remembering in learning. Memory is one of the important aspects that affect student performance in learning. In addition to sleep duration, the age factor can also affect short-term memory. This study wants to find out if age, sleep duration, and learning duration have an impact on short-term memory. This study incorporates elements of cognitive ergonomics because it measures short-term memory performance to assess how people process information and how they maintain it in their memory. Based on the results of multiple linear regression tests, the R Square value was 0.328 and the Adjusted R Square was 0.272. The age variable has a significance value of 0.001. The coefficient value on the age variable is 0.303 and is positive. This positive value indicates that increasing student age will increase the value of short-term memory. This shows that the higher the age of the student, the higher the ability in short-term memory. The sleep duration variable has no significant effect on short-term memory. The learning duration variable has no significant effect on short-term memory.
