For my thesis, I want to investigate whether voice pitch and voice tempo (individually and combined) [X] influence the purchase intention of advertised food products [Y]. In addition, I expect two mediators [M1 and M2], so I expect to test my hypothesis via model 6 of the Hayes Process Macro test in SPSS.
However, I am not sure whether Process is suitable as I have four conditions (high pitch-fast tempo/ high pitch-slow tempo/ low pitch-fast tempo/ low pitch-slow tempo) in my X variable. Is this possible?
