1. Token Economy Systems: A token economy system involves providing tokens (e.g., stickers, points) as reinforcement for desired behaviours. These tokens can later be exchanged for a preferred reward. Source: Kazdin, A.E. (2012). Behaviour Modification in Applied Settings.
   
2. Functional Communication Training (FCT): FCT teaches individuals to communicate their needs effectively as an alternative to problematic behaviours. By addressing the function of the behaviour, individuals learn appropriate ways to express their emotions. Source: Carr, E.G., & Durand, V.M. (1985). Reducing behaviour problems through functional communication training. Journal of Applied Behaviour Analysis.
   
3. Self-Monitoring: Self-monitoring involves individuals tracking their behaviours and emotions. This strategy increases awareness and helps individuals identify triggers and patterns.

4. Differential Reinforcement: Differential reinforcement involves reinforcing a desired behaviour while withholding reinforcement for undesired behaviours. This strategy can be used to increase emotional regulation skills by rewarding calm and appropriate responses. Source: Cooper, J.O., Heron, T.E., & Heward, W.L. (2007). Applied Behaviour Analysis.
   
5. Visual Supports: Visual supports, such as social stories or visual schedules, help individuals understand and manage their emotions. These tools provide clear expectations and routines, which can reduce anxiety and improve emotional regulation. Source: Gray, C. (1994). The New Social Story Book.
