Buschi, a male orang-utan, places square wooden shapes of different sizes and numbers in a quadratic area during puzzle tests with food rewards. As well as trial and error behaviour, the animal also displays planned effective behaviour. In tests with a labyrinth which can be completely surveyed and which has frequently altered passageways, the orang-utan pushes a magnet along a pane of glass which covers the labyrinth. In this way it can draw a metal sheet underneath the pane of glass through the passages to an exit at the edge of the labyrinth and it receives food for the sheet. A decision has to be made at the beginning of each experiment between two passagesways systems; wrong decisions cannot be corrected. The orang-utan orients itselfs in a planning phaes with unmistakable glances over the course of the labyrinth before making its decision.
