Jolien Glas Making stimulus processing understandable and workable



I'm Jolien Glas. I know from experience how confusing stimuli can be: sometimes you need a lot of stimulation, and other times you're so full that everything is too much. I've turned that curiosity into my work: why do you get overstimulated and what can you do about it?

\

Stimulus processing continues all day long. One moment you can enjoy music, people, touch, and company. The next, you can be utterly annoyed by every little sound from the very first minute. That's not "pretentiousness" or "reluctance." It's a nervous system that processes signals differently.


Why stimulus processing is so important

Well-functioning sensory information processing is a basis for learning, playing, working, sports and social contact.


When stimulus processing is disturbed, you often see this reflected in behavior or complaints, such as:

  • tense muscles
  • restlessness or urge to move
  • cry or get angry quickly
  • difficulty concentrating
  • sensitivity to sound, light, or touch
  • withdrawn or avoidant behavior
  • sleep problems (and sometimes more frequent urination)


    • These signals are usually a call for coordination: “This is too much” or “I need more input.”


Overstimulated vs. understimulated

An overstimulated person may react abruptly, angrily, violently, or explosively. This affects the atmosphere at home, in the classroom, or at work—and the reactions of others often become less helpful as well.
An understimulated person will actually seek out stimuli: moving, fidgeting, making noise, testing boundaries. This too can be experienced as "disruptive," while it's often a way to keep the system alert and regulated.


Recognize, understand and act – with confidence

I help parents, teachers, and professionals recognize signals from the body and nervous system and better understand behavior. No standard lists, but practical tools tailored to your child, your class, your family, or your team.


Together we look at behavior as communication: what does the body tell us, what does the nervous system ask for—and which adjustments make it easier?


For whom

I mainly focus on:

  • Parents who are looking for more peace, understanding and structure
  • Teachers/pedagogical staff who want to guide students better
  • Professionals in healthcare and education who want to deepen their knowledge of stimulus processing
  • Even when stimulus processing plays a role autism


About me

I'm a down-to-earth North Hollander, an emotional person and a doer. My strength lies in observing, analyzing, and translating behavior into concrete solutions. I see the strengths of children (or adults), read their body's signals, and help you tap into them—down-to-earth, engaged, and focused on real change.


In the spring of 2026 I further deepen my expertise with a course at a training institute Siem.


Take the first step

Want to discover how to gain more peace and control over stimuli—at home, at school, or at work? Feel free to contact me. Together, we'll make sensory processing understandable and workable.
