Final answer:
Addictive design features include increasing rewards, autoplay and countdown mechanisms, and regular alerts that encourage ongoing engagement. Settings to control notifications can help mitigate addiction, but are not a feature of addictive design.
Step-by-step explanation:
Features of addictive design typically include elements that encourage users to continue engaging with a service or product. Some of these features are:
- Rewards that increase as you play more, which can create a sense of achievement and entice the user to continue using the product.
- Use of autoplay and countdown features which can create a sense of urgency or a 'fear of missing out', encouraging continuous engagement.
- Regular alerts that can create a habit loop, with notifications acting as a cue to engage with the app or game.
On the other hand, settings that allow control over the number of notifications are typically designed to mitigate the addictive nature and give users more control over their engagement with technology.
