Factors affecting subjective estimates of magnitude: When is 9 > 221?

112 undergraduates separately judged, the size of the numbers 9 then 221 or 221 then 9 on a 10-point scale or on a continuous line that were both anch ored only at the extremes by "very, very small" and "very, very large." Rep licating the 1999 Birnbaum study, 9 was given a higher rating than 221 when the numbers were judged first by different people on the numerical scale. However, 9 was given a similar or smaller rating than 221 in the other cond itions. The results are discussed in terms of context effects.
