The relevant concept in these psychological studies is preattentive processing. In modeling the human visual system, psychologists have identified properties that improve discriminability. In these figures adapted from Julesz (1981), most people quickly detect the presence of arrows among the triangles. Less quickly detected are the upper-right triangles among the lower-left triangles. 2)3C%$. $1"0(P*=&0)*02(Z)"=&'&#<(*F(),"##$%5'*#( )<1=*')2(4##5-[[)#"#M,*15+#&0J@*%J[ 0$T)'$##$%["%,4&S$@4#1'2(N*'(6XU6V2(5@(Q en they are proith a good deh-quality plots ents. symbol set into display any Which is easier to see different group? iased data disploration tion hieved, but disdeoff.

Line crossings, terminations, lengths, and orientations, as well as other properties, are detected preattentively (Healey, Booth, and Enns, 1996).
