Shiri Melumad, Associate Professor of Marketing at the University of Pennsylvania Wharton School, conducted three field studies and two control experiments for her research.

In the first survey, Melumad observed 300,000 Twitter posts at 12 hour intervals, and posts written on smartphones were 47% more likely to use the first person than posts on PC, and family members It was said that 52% of them mentioned it. 'Consumers are more likely to convey emotions and thoughts on their smartphones, and are more likely to talk about their family and friends using terms such as 'I' and 'us,' Melumad said.

In the second study, we randomly extracted more than 10,000 reviews posted on TripAdvisor on a travel review site and asked natural language processing software and 1380 subjects to evaluate the content. ..

As a result, it was determined that natural language processing software often includes first-person reviews written on smartphones and often refers to friends. Human subjects also determined that the evaluation on the smartphone was 'more talkative about myself and compelling'. Melumad sees that restaurant reviews written on smartphones are intriguing to the reader, which is an important insight for corporate marketers.

And a third survey showed that people were more likely to disclose their personal information to ads displayed on their smartphones than to ads displayed on their PCs.

Control experiments, on the other hand, have shown that smartphone screens focus people more than PC screens. This is a phenomenon known as 'Attentional narrowing' in psychology. For example, 'in a stressful situation like going to the emergency room of a hospital, the driver concentrates only on what is in front of him. , Do not see pedestrians at the end of the road.' Such narrowing down of attention was also seen when tweeting on smartphones, when writing reviews, answering survey questions, and when asked about the crimes committed.

Mr. Melumad announced in a past study that 'smartphones are adult pacifiers', but he said that 'comfort' with smartphones will lead to more concentration of users and disclosure of their information I am.

When companies do market research, smartphones can be used to gather more honest and open information from respondents, Melumad said. In addition, restaurants can get more convincing content by asking them to write reviews on their smartphones, and when a company deals with product reviews, it is a consumer's preference to focus on the content written on smartphones. It's easier to get, said Melumad.
