Abstract: | 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. |
