| Abstract |
Memory search performance is commonly required in many daily life and professional careers. Sternberg Memory
Search Task (MST) is originally designed to test working memory (WM) retrieval function. However, in different
scenarios, memorizing a string of letters (i.e., stimulus items in original (MST) may not be able to represent the real
task characteristics, in this case for a specific soccer player population. Therefore, a modified MST was designed
based on literature review and interview with soccer players. With the same numbers of WM requirements with the
original MST, the modified MST was designed to adopt numeric (player numbers) and color codes (team uniform) as
stimuli. The objective of this study was to preliminarily compare subjective workload perception during the original
and 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-Task
Load Index (NASA-TLX). In general, the results showed increase in workload intensity to induce higher workload
perception for both test conditions. Mental Demands and Effort contributed as major demanding components of this
cognitive 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 test
similar demanding workload component target, as compared with the original MST. However, since different types of
symbolic information posed different levels of mental workload perception, the task stimuli should be carefully designed
to represent actual characteristics of the task of interest. |
