The technique of tracking external information search and processing aims to analyze how an individual, such as a decision-maker, collects and uses information to guide their choices. This approach was initially developed by Jacob Jacoby, Robert Chestnut, and William Fisher in 1978, but it is experiencing a resurgence of interest today due to the abundance of information available online. According to Christine Petr and Aurélie Hess-Miglioretti, the information sources consulted by consumers have evolved considerably. Audio and video content are now frequently used, primarily found on the internet. The digital presentation of data allows for adaptation to the modern media used by consumers. Digital formats offer a better understanding of decisions made under experimental conditions that closely resemble real-world situations. Furthermore, they offer the possibility of using various formats to disseminate the same message or information, which facilitates studies on the impact of form (iconographic or textual) on the decision-making process.
