Procedures
All authors were part of the British Association of Art Therapists personality disorder special interest group. Springham approached David Thorne and Julie Brooker to take part in the experiment. It was assumed that the minimum number needed for a group was three. They arranged to meet for one day to undertake an art therapy group in as realistic a manner as possible. They agreed to keep content confidentiality between them because they attempted to speak about emotionally live personal issues for themselves.
A long period was given over to art-making (2.5 hours) and each participant videoed themselves during this time, involving three video cameras. Following this they formed a group and discussed each participant's artwork in turn (1 hour 23 minutes total). No-one took the role of therapist. The participants were videoed as they viewed and discussed the image with the camera behind the image as per Figure 2. This replicated features of the still face experiment (Tronick et al., 1975).
