Minimally Effective Interpolated Stimuli in Weight Discrimination

The question of minimally effective weights was investigated by using an interpolated anchor paradigm. The weight series of 100 to 300 g, at 50-g-step intervals, was shown to be significantly affected by an interpolated anchor of 0.5 g, thus demonstrating a reduction in the region of ineffectiveness. The results were discussed in terms of procedural artifacts in the weight-judging methods reported in previous literature.
