I did my Master's on this subject, and had to chance to read Attneave and
the rest of the literature in depth. Information theory as applied to
psychology, as popularized by Attneave after Garner & Hake, has
nothing at all to do with transmission of anything. When applied to
traditional absolute judgment (identification) experiments, for example, it is
merely an alternative measure of short-term sensory memory. Which has
nothing to do with Claude Shannon's "general communications system". In
your case, memory capacity is probably what the analysis will
indicate. I am surprised that anyone uses the Garner-Hake information
approach anymore; mathematical psychologists (Duncan Luce, Donald Laming, Sandy
MacRae, etc.) recognized its severe limitations years ago and abandoned
it. So (eventually) did acoustics users like Neff and Lutfi. The
human being is NOT a Shannon communication channel. Granted, the
measures that result from processing the confusion matrix are covariance
measures of a sort. In that case, ordinary covariance
measures may provide a more meaningful way of analyzing your data. In
response to your question, then, none of TRANS, TRANS/INPUT or TRANS/TI are
appropriate measures for your purposes. Information theory doesn't work
that way. Attneave got the math right, but that had already been
done; but Attneave's interpretations (after Garner & Hake) were all
dead wrong. - Lance Nizami BSc (Physics) MSc (Biomedical Engineering) PhD
