ABSTRACT
The Postcard Sorting was expressly not intended as a test, but only as a means of obtaining within the space of a short interview information about a child's interests and attitudes at the moment. Any interpretations that have been made, as regards bias of temperament, on the basis of the Postcards answers, are therefore illustrative rather than conclusive, since it cannot be assumed, without further research, that the answers to the cards do express permanent or stable attitudes. The chart is only a diagrammatic and greatly over-simplified statement, useful as a means for summarizing an immense complexity of observations, but arbitrary, and devised simply for the sake of clearness. Although the chart was only intended as a convenience, some slight statistical confirmation of its underlying idea was actually obtained when a comparison was made between the Postcard answers for a 'satisfactory' group and a 'D' group.
