7.30 Non-Arbitrary Relational Responding
This is the open-access version of this module and your progress is not tracked or recorded
When the relations are based on the physical properties of the stimuli, this type of relational responding isn’t very remarkable. Physical properties just means the way a stimulus looks, sounds, smells, feels, or tastes. In the example of placing the stars in the boxes, the relations are determined by the physical properties (in this case, the size) of the stars. Not to take anything away from your stellar performance, but a monkey could be trained to put objects in the boxes in order of size like you did.
