People with AS have a **powerful need for sameness and predictability**, manifesting as:
**Resistance to change:**
- Changes in routine produce real discomfort
- Attempts to control situations to avoid discomfort
- NTs may misinterpret these behaviors as selfish or uncaring
- Environmental changes (e.g., furniture rearranged) cause upset
**Case example:** A man with sudden severe chest pain (suspected heart attack) was told by his wife with AS that it was time to go to the airport — he could come or not as he pleased. Her response: "Call 911."
**Inflexibility:**
- Cannot shift attention easily
- Once a decision is made, impossible to change mind
- Cannot look at something from a different perspective
- Disruption to routine can make concentration impossible
**Example:** A college student skipped class and went home when his ride took a different route — he couldn't "settle down and study" without things going "in the right order."
