In the present study, the relationship between performance on temporal and pitch discrimination and psychometric intelligence was investigated in a sample of 164 participants by means of an experimental dissociation paradigm. Performance on both temporal and pitch discrimination was substantially related to psychometric intelligence (r=.43 and r =.39). Regression analysis and structural equation modeling suggested that both psychophysical domains can be considered as valid predictors of psychometric intelligence. Both predictor variables contributed substantial portions of both shared and unique variance to the prediction of individual differences in psychometric intelligence. Thus, the present study yielded further evidence for a functional relationship between psychometric intelligence and temporal as well as pitch discrimination acuity. Eventually, findings are consistent with the notion that temporal discrimination - in addition to general aspects of sensory discrimination shared with pitch discrimination reflects specific intelligence-related aspects of neural information processing.
在本研究中，通过实验性分离范式，对164名参与者样本进行了研究，以探讨时间和音高辨别能力与心理测量智力之间的关系。时间辨别和音高辨别能力均与心理测量智力显著相关（r = 0.43和r = 0.39）。回归分析和结构方程模型表明，这两个心理物理学领域均可被视为心理测量智力的有效预测指标。两个预测变量对心理测量智力个体差异预测中的共享方差和独特方差均有很大贡献。因此，本研究进一步证明了心理测量智力与时间辨别以及音高辨别敏锐度之间存在功能关系。最终，研究结果与以下观点一致，即除了与音高辨别共有的感觉辨别一般方面外，时间辨别还反映了神经信息处理中与智力相关的特定方面。
