Noise, attentional selectivity, serial reactions and the need for experimental power
Laurence R Hartley · British Journal of Psychology · 1981
The paper draws attention to the very low experimental power of a recent attempt to replicate Hockey (1970). A successful attempt to replicate Hockey (1970), using considerably more experimental power, is reported. It is also pointed out that the power of Forster & Grierson's attempt to repeat Hockey's finding without the presence of response‐produced cues is so very low that a successful result is not to be expected. Finally a number of problems in the application of Poulton's composite theory of noise to serial reaction performance are pointed out.
