“…In particular, the latter assumed, as was done earlier by McGill (1963McGill ( , 1967, Siebert (1965Siebert ( , 1968Siebert ( , 1970, and others, that the signals are, to a first approximation, represented internally as independent Poisson processes on a number of parallel channels. The intensity parameters of these Poisson processes are assumed to be increasing functions of signal intensity.…”

Three lJIOt*I-for m..nitude estimation were investitated, and a sufficient number of responses w.e obtained to make reasonable estimates of both the mean and variance of the responses. The conventional magnitude estimate procedure, without a standard signal, appeared to produce the most sensible data. The best method of establishing the central tendency of the data appears to be the plot of the mean ratio of successive responses against the intensity ratio of the corresponding signal intensities. When this is done, the average response ratio increases roughly as a power function of the signal ratios. The coefficient of variation, olm, varies from about 0.1 for small signal ratios and increases to 0.3 at about 20 dB and greater signal separations. The distribution of response ratios appears to be reasonably well approximated by a beta distribution. The change in aIm with signal ratio is suggestive of an attention mechanism in which the sample size depends on the location of the attention band. The ratio estimation procedure suffers badly from discrete number tendencies.

“…The change in level at the harmonic is the cue for detection. Thus, the Weber fraction decreases as the level McGill (1967) has pointed out that the neural counting model is unable to predict changes in absolute threshold as a function of signal frequency. This does not appear to be a serious limitation since, as McGill notes, the constant a in Eq.…”

“…In order to account for the fact that signal threshold is a function of signal frequency, it must be the case that the constant, a, in Eq. 1 is not a constant, but rather depends on the signal frequency, as McGill(1967) has suggested. REFERENCES of the standard increases.…”

“…The entire Perception & Psychophysics, 1971, Vol. 9 (6) latency would then be similar to those from a general gamma distribution (e.g., McGill & Gibbon, 1965), and more complicated analyses would be necessary to obtain the LP curves of the underlying counting process. This also applies in the case of simple reaction time.…”

“…Sequential observations have been studied by Swets and Green (1961), but there the observations were overt and repeated presentations of the stimulus were thus necessary. Another form of counting model has been proposed by McGill(1967) to describe auditory detection outcomes; this may be modified to describe detection latencies. Choosing between these interpretations is clearly an experimental problem, particularly with regard to the use of variations in the basic signal detection situations.…”

A model for two-choice discrimination based on a process of simple counting is described, and two experiments are performed to test the predictions of the model concerning the graph of latency as a function of response proportion. Two main forms of this graph are identified and predicted to arise in different circumstances. The experimental results support the model, and its possible extension to other psychophysical situations, especially signal detection, are then discussed. It is compared with a model derived directly from the detection situation, and the usefulness of testing these models is pointed out.
