I am considering an experiment in which I use existing commerical packages from nation brands as experiment stimuli to enhance ecological validity. However, I do not know if this can raise up some concerns over copyright. Especially marketing journals usually aks authors to present the stimuli they used in paper manuscript.
Can I use these existing commerical packages as experiment stimul?
Can I also present these packages in my article?
Shall I get permission to use them from the brand/company?
Thanks for your information.
