Webcontrast wisely. However, the advantage is that planned comparisons have greater statistical power than post-hoc tests. Of the contrasts available in SPSS, most are fairly similar, but simply change which groups are being compared (and some compare multiple groups simultaneously). The one that is a bit different is the “polynomial” contrast.
