Lowenfeld Mosaic Plates; 144 coloured plates for use with the Lowenfeld Mosaic Test, devised by Margaret Lowenfeld as a therapeutic diagnostic technique, distributed by Badger Tests Ltd; used by the Institute of Education, University of Liverpool, c.1960-1990.

Margaret Lowenfeld (1890-1973) was a paediatrician who became a pioneer of child psychology and psychotherapy. She recognised language is often unsatisfactory and even impossible as an expressive medium for children. This is particularly the case with traumatised children. Lowenfeld also recognised play is essential to their development. She invented non-verbal techniques to enable them to convey experiences. This included Lowenfeld Mosaics – sets of plastic tiles in five different geometric shapes and six primary colours. The child was given the tiles and a wooden tray and then used the pieces any way they liked. The psychologist then interpreted the patterns. This box contains images of a wide range of possible results to help with this interpretation.

Her mosaics produced a powerful diagnostic and therapeutic instrument. This set was used at the Institute of Education at the University of Liverpool.
