Dear, one experimental sample design and one control sample can be used .... Greetings

The effects of vanity, a component of grandiose narcissism, on social media interaction, creation, and content consumption can be studied to learn more about how different stimuli affect online behaviour. It's essential to carefully plan the research and take certain key factors into account when conducting online studies and manipulating narcissism through visual or audiovisual stimuli. Here are some ideas and pieces of literature to help you with your research:

1. Make sure your research complies with ethical standards by obtaining participants' informed consent, ensuring their anonymity and confidentiality, and minimising any potential harm to them.

2. Randomization: To lessen bias and enhance the internal validity of your study, randomly assign participants to the two groups (vanity stimulus group and control group).

3. Select stimuli that are associated with conceit and inflated narcissism. The study by Foster et al. (2015) may serve as a good starting point, but you might need to modify or develop stimuli unique to your research context.

4. Measures of narcissism that have been proven to be reliable should be used to gauge the participants' initial levels of narcissism. A popular tool for this is the Narcissistic Personality Inventory (NPI).

5. Visual/Audiovisual Stimuli: You can use pictures, videos, or audio clips that have themes of vanity, superiority, admiration, or self-importance to manipulate narcissism. Make sure the stimuli are both visually appealing and appropriate for social media contexts.

6. Pre-test and pilot study: Before beginning the main study, conduct a pre-test or pilot study to gauge the success of your stimuli and pinpoint any potential problems or improvements.
