Assorted psychological tests for studying language, used by Aberdeen City Council Psychological Services.

The Blacky Pictures were developed in 1950. They have been described as ‘a technique for the exploration of personality dynamics’ in children. They were developed by G. S. Blum in 1949. Each of the 12 cards making up the test feature a dog named ‘Blacky’. Each cartoon represents a different stage of psychosexual development (the way sexual behaviour develops, according to psychoanalysts). The test also looks at family relationships. It features an image of a dog chewing a collar with the word MAMA on display. The test taker invents a story based on the image. The test is not widely used today. This image is one of 68 pictures forming the psychological tests used by Aberdeen City Council Psychological Services.
