🧠🎨 What is Mentalisation and Why Does it Matter in Play Therapy?
Mentalisation is our ability to understand what is happening in our own minds and in the minds of others.
It is the capacity to wonder:
✨ What am I feeling right now?✨ What might be driving my behaviour?✨ What might somebody else be thinking or feeling?✨ Could there be another explanation for what just happened?
When children become overwhelmed, frightened, angry, ashamed, or dysregulated, this capacity often temporarily disappears. Instead of being able to think about their feelings, they may act them out through behaviour, conflict, withdrawal, perfectionism, control, or emotional outbursts.
This is particularly relevant for children who have experienced trauma, loss, disrupted attachment relationships, or chronic stress. Research suggests that adverse childhood experiences can impact a child's ability to understand and reflect upon their own internal world and the intentions of others.
🎭 How does this link to play therapy?
Play therapy naturally creates opportunities for mentalisation to develop.
Through play, storytelling, art, sand trays, role play, metaphor, and symbolic expression, children begin to externalise experiences that may feel too overwhelming, confusing, or complex to put into words.
Rather than asking directly, "How do you feel?", the therapist may become curious alongside the child:
🔎 "I wonder what this character might be feeling?"
🔎 "What do you think the dragon needs right now?"
🔎 "I notice the castle keeps getting stronger each week."
In many ways, the therapist becomes a gentle detective, helping the child find clues about thoughts, feelings, bodily sensations, needs, and relationships.
I came across an interesting article exploring the concept of mentalisation and its application within art therapy. Whilst the article focuses specifically on art therapy, many of the ideas resonated strongly with my experience as a play therapist. The piece highlights how creative expression can provide a bridge between experience and language, helping children make sense of feelings that may initially be too big, confusing, or overwhelming to put into words.
It is well worth a read for anyone interested in child development, emotional wellbeing, creativity, and the therapeutic process.
