Previous research has highlighted poor test-retest reliability when using reaction time (RT) as the primary metric. To address this, the study investigated whether accuracy measurements from a limited dataset could improve reliability. Methods: Two experiments were designed to test this hypothesis. Experiment 1 replicated the methodology of Anderson et al. (2011), while Experiment 2 utilized accuracy measurements with limited data as the primary focus. Each experiment comprised a conditioning phase followed by a test phase, repeated across two sessions. Monetary rewards were provided exclusively during the conditioning phase. The test phase included three conditions: high interference, low interference, and no interference. A 2 (time) × 3 (interference condition) within-subjects ANOVA and a reliability analysis of the high interference effect were conducted. Results: The results revealed that the interference effect of value stimuli was significant only in the experiment using reaction time as the primary measurement. Conversely, accuracy data from the limited dataset failed to effectively capture the attention-related effects of value interference. Reliability analysis showed poor outcomes for difference scores but demonstrated strong reliability when single scores were used. Single scores were associated with reduced measurement error and increased between-participant variability. Conclusion: The findings indicate that replacing difference scores with single scores can significantly improve the reliability of the VDAC task. Single scores offer advantages, including lower measurement error and greater variability across participants. However, for the interpretation of a single score to be meaningful, the significance of the VDAC effect must be a prerequisite.反應時間信度價值驅動注意力資料有限正確率reaction timereliabilityvalue-driven attentional capturedata-limited accuracythesis
