text: Disturbed BEHAVIOUR of animals in an EXPERIMENT when they are faced with an impossible problem. This PHENOMENON was discovered by PAVLOV when he rewarded a dog with food for responding (by salivating) to a circle and then withheld the reward when the stimulus was an ellipse. Pavlov gradually made the two stimuli more and more alike. When the point was reached at which the dog could no longer discriminate the circle from the ellipse the animal lashed out in a frenzy of wild and random behaviour. Whether this behaviour can be equated with human NEUROSIS is a matter of long-standing dispute among psychologists.
explanation: The text describes an experiment by Pavlov involving animals' behavior when faced with an impossible problem. It explains how Pavlov's dogs reacted when they could no longer distinguish between a circle and an ellipse, leading to a frenzy of random behavior. The text also mentions the debate among psychologists about whether this behavior can be equated with human neurosis.
