Subject: summary: two wavelength inhibition

I thank everyone who helped.

I now post a summary because it is impossible for interested parties to
find out anything otherwise. May I urge the list owner to move over to
a more "normal" mailing list set-up, where respondents can reply to the
list? Since this is a closed & moderated list, junk email is certainly
not a concern. (This is not a criticism! I thank Hoover for his
efforts!)

I was interested in an expt where two flashes (or steady lights) are
presented at the same time. The flashes have different wavelengths.

The classic experiment appears to be
Boynton, Ikeda & Stiles VR,v. 4,pp.87-117 (1964).
Although they do not plot the results in the 2D plot a la Rashbass that
I was looking for. This should be easy enough to construct from their
figs though.

Kranda & King-Smith in Vision Research 1979, v.19, 733- 45
also appears to be a classic.

This one sounds very relevant, though I haven't seen it:
Stromeyer et al. (1978). Detection of
red and green flashes: evidence for cancellation & facilitation. Sensory
Processes, 2, 248-271.

People also cite:
Thornton, J. E. and Pugh, E. N. (1983). Red/green color opponency at
detection threshold. Science, 219: 191-193.
I have looked at this one. Although they do produce the plot I am
looking for, I don't understand how this plot was derived. Their
expt appears to be very different from what I wanted--they basically
measured spectral sensitivity functions. There appears to be no
presentation of pairs of wavelengths. Their plot is derived using some
transformation which is not explained (not their fault, due to Science's
space limitations). It seems all too indirect for me.

Guth, Donley and Marrocco, Vision Res. 9, 537-575 (1969), Fig. 8.
This is the right sort of expt and plot, but the data don't show any
inhibition! (Main point of plot for me).

Here are other refs, none of which I have seen. Some are for version of
expt where the flashes had diff wavelengths PLUS were presented at diff
times.
