Demonstrates in four parts, the four forms of learning.
Conditioned response learning forms are represented in three examples: 1) leg flexion initiated with electric shock and conditioned to sound;2) the running response in an exercise cage initiated by shock and conditioned to sound; 3) general activity in a suspended cage initiated by shock and conditioned to sound, with the medthod of kymographoc recording indicated. The second learning form, problem solving, is exhibited in two examples: 1) a cat learns to pull a string in order to drag a dish into position for eating. Several unattached strings are also presented to cat. In second scenaroi, cat never learns to distinguish between attached and unattached string, an example of "positional learning". 2) the cat learns to push a a ball into a hopper in order to open a door exposing food.
The third learning form, discriminative learning, is shown in film 3, as three examples: 1) the cat learns to select the door on which as triangle has been painted and 2) the cat learns to select the brighter of two doors before pressing a pedal which releases the obstruction to the food reward. 3) the cat learns to choose a door behind which a sounding device has been placed. The fourth learning example , compound learning, is illustrated in two sessions 1) the cat learns to press two pedals alternately in order to open the food troughs. 2) The cat learns to pull a string releasing a ball which is pushed into a hopper exposing food. Silent.
