Inclusion criteria

Inclusion criteria: All men and women between the ages of 18 and 59 years that are registered on the ProA or Kurundata platform will be eligible to participate in the study. The videos contain no speech and are therefore language independent. We will translate the English questionnaire into Chinese. Participants from USA must have reading competency in English and participants from China must have reading competency in Chinese to participate in the study.

Exclusion criteria

Exclusion criteria: Exclusion criteria for all data collection is those who do not meet the above listed inclusion criteria. Participants who are out of the age range will be excluded from the final analysis. If a participant can not read one of the translated languages, the ProA or Kurundata platform will inform the participant that they are not eligible for participation in our study. Participants will be automatically timed-out from the online platform if they take more than 45 minutes to complete the study. The data will then not be used for evaluation.
