Logic and Intuitive Basis of the First Impression of the Child's Intelligence

The article describes results of an experimental research. In this research, experimental subjects were shown a short video of a child and asked to give their opinion of the child's intelligence. The experimenter wanted to know how precise such an evaluation can be, which basis it is given on, which behavioural features are used, and how the verbal description of the child's behaviour influences the outcome of evaluation. The intelligence was measured with J. Raven's Standard Progressive Test.
