IISCA is an acronym for an interview-informed synthesized contingency analysis. A successful IISCA serves as an effective baseline context to treat problem behavior and develop important social repertoires. SBT is the acronym for Skill-Based Treatment, a type of intervention based on the principles of ABA used to reduce problem behaviors. Today, it appears to be one of the most effective interventions in the literature for the treatment of problem behaviors and the teaching of new skills in individuals with autism or disabilities.

Gentle Timer is a cheerful timer with cute animated characters. Set a time, and a character walks across the screen as the timer counts down. When it reaches the other side, time is up. You can always see how much time is left. • Pick a cute character, an animated background, and calming music. • Your character can leave a trail of sparkles, rubber ducks, or baby chicks. • A race car can drive around the timer and finish when time is up. • Choose a pet to pop up and cheer you on. • Your pet also shows on your Lock Screen, Home Screen, and Dynamic Island. • Fun animations play when your timer starts and when it ends. Use it for brushing teeth, homework, cooking, reading, or a short break at work. It also has a stopwatch, breathing exercises, and a Pomodoro timer for work and breaks. You can run more than one timer at once, too. There is also a simple Apple Watch timer. Free to download, with no ads and no subscription. Unlock more characters, pets, backgrounds, and music with a one-time purchase.
