The processing of prices across numerical formats

Area of Science:

• Cognitive Psychology
• Neuroscience
• Economics

Background:

• Understanding how numerical magnitude is processed is crucial for various fields.
• The format of numerical information, such as digits or words, may influence cognitive processing.
• Previous research has explored magnitude processing, but the impact of specific price presentation formats requires further investigation.

Purpose of the Study:

• To investigate whether the format of price presentation influences the processing of numerical magnitude.
• To examine the effects of Number-Monetary Category (NMC) and Unit-Decade (UD) compatibility on price magnitude processing across different formats.

Main Methods:

• A price comparison task was employed using two-digit prices.
• Prices were presented in three formats: Arabic digits, written number words, and auditory number words.
• Stimuli included NMC compatible/incompatible and UD compatible/incompatible prices in euro currency.

Main Results:

• Number-Monetary Category (NMC) compatibility effects were observed across all tested numerical formats (Arabic digits, written words, auditory words).
• Unit-Decade (UD) compatibility effects were not found in any of the numerical formats.
• These findings suggest that the relationship between numerical value and monetary unit significantly influences magnitude perception, irrespective of format.

Conclusions:

• The format of price presentation influences magnitude processing, particularly concerning the relationship between numerical value and monetary category.
• The hybrid model of multisymbolic magnitude processing provides a framework for understanding these effects.
• Future research should explore the underlying neural mechanisms and practical implications of these findings in consumer behavior and financial decision-making.
