Psychological ownership of cash and mobile payments, manipulation check of mental simulation for experimental scenarios, and measurement of willingness-to-pay and willingness-to-accept

In Experiment 1, participants were presented with five questions as a manipulation check of mental simulation of the scenario (i.e., purchasing a humidifier at a flea market). Participants who correctly answered the questions were included in the analysis. The top 5% and bottom 5% of the willingness-to-pay responses that participants indicated for the item to be purchased in the experimental scenario were excluded as outliers. The participants were asked to indicate the amount that they were willing to pay using their preferred (cash or mobile payment) and non-preferred (cash or smartphone payment) methods of payment.

In Experiment 2, four experimental scenarios were prepared and participants responded to the situation in any two scenarios. In each experiment, participants were asked to respond to ten questions for a manipulation check of mental simulation of the scenarios (in both, concert tickets were purchased and transferred as a smartphone remittance). Those who responded correctly to all of the questions were selected for the analysis. In Experiment 2-1 the ticket was purchased with cash and given to a friend, in Experiment 2-2 the ticket was purchased with cash and given to another person, in Experiment 2-3 the ticket was purchased with a mobile payment and given to a friend, and in Experiment 2-4 the ticket was purchased with a mobile payment and given to another person. Respondents were asked to indicate willingness to accept using their preferred method of receipt (cash or mobile payment) and the amount they did not want to receive by their preferred method of receipt (cash or mobile payment). Responses from the top 5% and bottom 5% of the willingness-to-accept amounts in the experimental scenario were excluded from the analysis as outliers.

The measures of psychological ownership for cash and mobile payments were common in Experiments 1 and 2. Respondents were also asked about their gender, age, and experience with mobile payments.
