Background/Objectives: The purpose of this study is to construct standardized data through a computerized neurocognitive function test. Methods/Statistical analysis: This study involved 180 adults aged 20 to 79 years. All subjects were evaluated with six attention test sub-domains of a computerized neurocognitive function test. The attention tests consisted of a visual continuity performance test (VCPT), auditory continuous performance test (ACPT), visual vigilance test (VVT), auditory vigilance test (AVT), trail-making test (TMT), and stroop test (ST). For statistical analysis, independent t test and Pearson correlation analysis were performed. Findings: There was no significant attention difference between the sexes (p >.05). Correlation analysis showed that attentiveness decreased significantly with age (p < .05). We have presented the reference values of six attention tests according to the age group. Improvements/Applications: The reference value data for the six computerized neurocognitive function attention test sub-domains may be helpful for distinguishing attention problems in clinical practice.
