非聽覺性參與者特質影響數字辨識表現：來自不同掩蔽聲類型與空間線索任務的證據

// Non-Auditory Participant Characteristics Influence Digit-Perception Performance: Evidence From Tasks Varying in Masker Type and Spatial Cues

220名16–17歲正常聽力青年接受三項數字感知測試（兩次）｜SSN無關；babble單變項微弱、調整後消失；空間選擇注意與教育、社經弱勢及音樂經驗獨立相關，前向數字廣度（短期記憶）無預測力｜實務：空間性測驗易受非聽覺混淆，所謂音樂家優勢調整後約減1/3，臨床與研究應控製社經與教育因素。

// This study tested whether education, forward digit span, socioeconomic deprivation, and musical experience predict performance on three digit-perception tasks (digits in speech-shaped noise, digits in spatially separated babble, and a spatial-selective-attention task) in 220 young adults (aged 16–17) with normal hearing, each tested twice. Researchers used linear mixed-effects models to examine single-predictor and multivariate associations. Digits-in-SSN showed no associations, digits-in-babble had modest single-predictor links that did not survive multivariate adjustment, while spatial-selective-attention performance showed robust independent associations with education, deprivation, and musical experience; forward digit span predicted none. The results indicate spatially demanding digit tasks are vulnerable to non-auditory confounds, and the apparent musician advantage is partly explained by sociodemographic confounding (reduced by ~1/3 after adjustment).
