explain Asch's experiment
123 men were tested each one were in a group with other particpents
each participant saw two large cards on each trial
the line X on the lefthand card is the standard line
a.b.c are the comparison lines
one of the comparison lines is always clearly the same as line X, the other two are obviously different
on each trial each participant had to say out loud which of the comparison lines was the same as length X
