Because predictability is such a central need, many of the barriers below are less about the content of a session and more about how much notice, structure, and explicit framing surrounds it. 

Setting 

What it looks like 

Lectures / seminars 

Unplanned changes to room, time, or format, sprung with little or no notice. 

Group work 

Unclear or informally negotiated roles; hidden social rules; fast-paced open discussion with no visible structure. 

Practical / lab sessions 

Sensory overload from noise, lighting, or crowding, which can make it genuinely difficult to focus on the task itself. 

Online learning 

Inconsistent page layout or navigation from week to week, forcing the student to re-learn structure repeatedly. 

Presentations / assessment 

Being unexpectedly asked to speak or perform without notice, which can trigger disproportionate anxiety relative to the actual task. 

Communication with staff 

Implicit expectations that are never stated explicitly, requiring the student to infer what is actually being asked.
