Memory search performance is commonly required in many daily life and professional careers. Sternberg MemorySearch Task (MST) is originally designed to test working memory (WM) retrieval function. However, in differentscenarios, memorizing a string of letters (i.e., stimulus items in original (MST) may not be able to represent the realtask characteristics, in this case for a specific soccer player population. Therefore, a modified MST was designedbased on literature review and interview with soccer players. With the same numbers of WM requirements with theoriginal MST, the modified MST was designed to adopt numeric (player numbers) and color codes (team uniform) asstimuli. The objective of this study was to preliminarily compare subjective workload perception during the originaland modified MST performance. Seven healthy male university students (average age of 30.7±8.0 years) were recruited to participate in this study. All participants were asked to perform both the original and modified MST including low and high workload intensity conditions. All subjective workload scores were collected by using NASA-TaskLoad Index (NASA-TLX). In general, the results showed increase in workload intensity to induce higher workloadperception for both test conditions. Mental Demands and Effort contributed as major demanding components of thiscognitive task type. Although overall workload of both tests was comparable, subscale workload scores of the modified MST found to be lower than the original MST. The findings suggested that the modified MST can be used to testsimilar demanding workload component target, as compared with the original MST. However, since different types ofsymbolic information posed different levels of mental workload perception, the task stimuli should be carefully designed to represent actual characteristics of the task of interest.
