This study investigated whether calibration and discrimination are distinct or related aspects of probability judgment accuracy by examining the effects of two different training techniques. Participants received either performance feedback or environmental feedback, and we measured their improvement in calibration and discrimination as a function of feedback type. Whereas performance feedback reduced participants' overconfidence and environmental feedback improved discrimination, neither type of feedback led to an improvement on the other component. In fact, environmental feedback led to an increase in overconfidence. We take these results as evidence that calibration and discrimination are dissociable abilities that require separate training techniques for improvement. Copyright 2000 Academic Press.
本研究通过考察两种不同训练技术的效果，探究了校准和辨别是概率判断准确性的不同方面还是相关方面。参与者分别接受了表现反馈或环境反馈，我们测量了他们在校准和辨别方面作为反馈类型函数的改善情况。表现反馈降低了参与者的过度自信，环境反馈提高了辨别能力，但两种反馈都未使另一成分得到改善。事实上，环境反馈导致过度自信增加。我们将这些结果作为证据，证明校准和辨别是可分离的能力，需要不同的训练技术来提高。版权所有2000年学术出版社。
