  • The study takes approximately 5–10 minutes
  • Adults aged 18+ with no visual impairments that would prevent you from viewing images correctly
  • No technical knowledge is required

Anonymity: Your responses are completely anonymous. No personal data is collected beyond your responses and automatically recorded timestamps.

Withdrawal: You may close this page at any time before submitting to withdraw. Once submitted, your data cannot be withdrawn due to the anonymous nature of collection.
