Such a computer could consist of at most 10126 pieces of hardware. , the well-known traveling salesman problem with a sufficiently large number of destinations).

8 times threshold with zero distracters. 5. The similarity of these predictions allowed Baldassi and Verghese (2002) to dismiss earlier support for the averaging model (Baldassi and Burr, 2000). SDT and the averaging model give very different predictions when distracters are replaced by additional targets (holding the total number of stimuli constant). In this case, the averaging model predicts an inverse proportionality between threshold and number of targets. Parkes, et al. (2001) confirmed this prediction using brief, but unmasked nine-item displays.

2) If distracters have zero tilt, their density and distribution can be abbreviated as fD (x) = f (x ; 0, s ) (3) Were the observer to identify the direction of tilt, the proportion of accuarate responses would be • y = t Ú fT (x)[FT (x) - FT (- x)]t -1 [FD (x) - FD (- x)]d dx 0 • (7) + d Ú fD (x)[FD (x) - FD (- x)]d -1 [FT (x) - FT (- x)]t dx , 0 where t is the number of targets with tilt m, and d is the number of distracters with tilt 0. , and Burr, D.
