Does mental number line training work?

In this study participants had to play a simple game based on making numerical estimations in attempt to improve their decision making skills. After nine sessions participants did improve in accuracy of simple every-day estimation tasks and were more confident in their judgment.     Sobkow, A., Fulawka, K., Tomczak, P., Zjawiony, P., Traczyk, J.…

The mechanism of non-numerical anchoring heuristic based on magnitude priming

Our decisions are often made under uncertainty. Research shows that numerical estimations may be biased by arbitrary number. In this study we explore further this psychological effect, testing how generating a different sense of magnitude may affect the subsequent numerical judgment.     Tomczak, P., & Traczyk, J. (2017). The mechanism of non-numerical anchoring heuristic…

Cross-modal anchoring: magnitude priming based on length leads to contrast effect in numerosity judgment

Magnitude priming is considered to be an effective method of influencing numerical estimations regarding general knowledge. However, in the study it was revealed that in case of estimating numerosity of rapidly displayed objects a contrast effect was found. The results suggest an interaction between spatial processing and attentional processes.     Tomczak, P. (2018). Cross-modal…
