TO THE EDITOR: In a recent article published in the Journal of Neurophysiology, Hawkins and colleagues (2015) show that evidence accumulator models (EAMs) and the urgency-gating model (UGM) are mathematically distinguishable in conditions where the sensory information used to make a choice is constant during the time course of a trial. With a model recovery method, they also demonstrate that th...

Two representations of the Bessel zeta function are investigated. An incomplete representation is constructed using contour integration and an integral due to Hawkins fully evaluated (analytically continued) produce two infinite series. This new representation, at integer values argument, produces results that consistent with known (values, slope, pole structure). Not surprisingly, studied foun...

on the instrument, its date, its inventor Lee or the manufacturing or supplying firm ofAL Hawkins Ltd, London. Another machine "The Sedigraph" made by a Swiss firm after the Second World War acted in a similar fashion with rather more sophistication. One of these instruments is also in the collection. The collection of old instruments nlow numbers about 1000 items which, it is hoped, will form ...

Three-dimensional CT was used to examine the atlantoaxialjoint ofa nine-year-old girl who presented with fixed rotation of the head 3.5 months after an apparently spontaneous acute torticollis. The method provided clear, anatomical images to show the site, extent and direction of the type-I rotatory fixation (Fielding and Hawkins 1977). The 3-D reconstructions helped to guide manipulation which...

A method of viewing multivariate data vectors and identifying among them outliers is described. The method is applied to two sets of benchmark data: Brownee's stack-loss data and Hawkins{Bradu{Kass data. All the outliers contained in these data are easily identiied. Generally, it is expected that the method will yield good results (i.e. will nd the outliers) for data having elliptical or nearly...
