Origin of the SEEV Model of visual attention distribution What's the original source of the SEEV (Salience Effort Expectancy Value) Model for predicting the distribution of visual attention? I've seen it mentioned in many papers and presentations but everyone of them lacks a reference to the source of this model.

Does anyone have a valid reference?
Wickens et al. (2003) is the earliest I'm aware of:

Wickens, C. D., Goh, J., Helleberg, J., Horrey, W. J., &amp; Talleur, D.
A. (2003). Attentional models of multitask pilot performance using
advanced display technology. Human Factors: The Journal of the Human
Factors and Ergonomics Society, 45(3), 360-380.

Actually, in that paper he cites Wickens et al. (2001), but I can't seem to find
a copy of this manuscript anywhere, and it has fewer citations:

Wickens, C. D., Helleberg, J., Goh, J., Xu, X., &amp; Horrey, W. J.
(2001). Pilot task management: Testing an attentional expected value
model of visual scanning. Savoy, University of Illinois Institute of
Aviation.

If you're using N-SEEV, cite one of these instead:

Steelman-Allen, K. S., McCarley, J. S., Wickens, C., Sebok, A., &amp;
Bzostek, J. (2009, October). N-SEEV: A computational model of
attention and noticing. In Proceedings of the Human Factors and
Ergonomics Society Annual Meeting (Vol. 53, No. 12, pp. 774-778). SAGE
Publications.
