在心理声学检测实验中，观察者的决定由两大类决定因素决定：（1）外部决定因素，例如特定波形是噪声中信号的可能性，以及（2）内部决定因素，观察者神经系统的瞬时状态，他的反应偏差，或对某些反应序列的偏差。这项研究的目的是通过测量观察者的一致性来确定这些因素的相对贡献。为了实现这一目标，在一系列两个选择性强迫选择试验期间呈现的音频信息被录音，并在稍后的时间向观察者重复。观察者判断的一致性通过确定一致性分数百分比来衡量：受试者同意他先前对这些序列的特殊试验的反应的次数百分比，其中在强迫选择试验的任何间隔中都没有出现信号。百分比协议范围在80%和55%之间，这取决于观察员和…
An observer's decision in a psychoacoustic detection experiment is governed by two broad classes of determinants: (1) external determinants, such as the likelihood of a particular waveform being a signal in noise, and (2) internal determinants, the momentary state of the observer's nervous system, his response biases, or biases as to certain sequences of responses. The aim of the study was to determine, via a measure of the observer's consistency, the relative contribution of these factors. To achieve this end, the audio information presented during a sequence of two‐alternative forced‐choice trials was taped and repeated to the observer at a later time. The consistency of the observer's judgments was measured by determining a percent agreement score: the percent of times the subject agreed with his previous response on those special trials of the sequence in which no signal occurred on either interval of the forced‐choice trial. Percent agreements range between 80% and 55%, depending on the observer and,...
