Noise", report, 11 February 2007, 12 pp.
We consider the detection of faint signal, very much
below the noise level. The series of signals is
presented to subjects for their
assessment, by haptic means, of the presence of the feature in one or other
of the two signals presented. We develop an approach based on visualization
of the dependencies between the signal, possibly containing the feature, and
another noise signal.

R.D. Roberts, G.W. Humphreys and A.M. Wing, "Temporal
constraints on ineractions across kinaesthetic
subject responses are evaluated
relative to correct outcomes (i.e.,
experiment design conditions). Here we include this aspect
in the analysis but also
carry out two "Turing test type evaluations". The latter are
based on two algorithms, which generally (but not always) outperform
the test subjects.
It is not our purpose to simply outperform the subjects: our algorithms
benefit strongly from prior information. Our algorithms are used
to baseline the subject responses. A multivariate data analysis not only
account the correct outcomes, the subject performance, and our two
also takes into account differentiation within the subject population.
Correlation Effect", report, 13 July 2007, 25 pp.
We describe the requirements for the modelling of the correlation
effect, the detailed algorithm, the program used, and sample output produced.
