CALL FOR PAPERS: 2ND-ORDER MECHANISMS
The Journal of the Optical Society of America A announces a call for papers to
be published in
a special feature issue on second-order visual processing mechanisms. Feature
editors for the
special issue are Charles Chubb, Andrew Derrington, and Lynn Olzak. The
deadline for submission
is December 1, 2000. Publication is scheduled for September, 2001. All
manuscripts should be prepared
according to the usual standards for submission to JOSA A and will be reviewed
in the same manner
as other JOSA A papers. Manuscripts should be sent directly to the Optical
Society of America Manuscripts
Office, as outlined in recent issues. You must indicate that the paper is to
be considered for the feature issue.
The scope of the feature issue is as follows: Many phenomena have now been
demonstrated that are beyond the direct scope of the multichannel model, yet
which might submit to second-order models. The effects to which such
second-order models have been applied include perceptual grouping of colinearly
oriented targets (e.g., Gabor packets) amid distractors; perception of
sinusoidal beat patterns; motion defined by stimulus attributes other than
luminance (e.g., stimulus contrast); preattentive texture segregation; many
search tasks; judgments of complex patterns implicating nonlinear interactions
between band-selective channels; contrast-contrast effects; brightness
illusions; illusory contours.
It remains unclear, however, whether full-blown second-order models are
warranted to account for some of these phenomena. For example, although
second-order models have been proposed to account for the perception of
motion defined by texture contrast, many researchers remain unconvinced that
human vision embodies a genuine second-order motion system. The relationship
between attention and second-order processes also remains unresolved, and
little is known about the neural physiology underlying these various
phenomena. We solicit papers related to these phenomena and topics.
