A man is looking at a tree. What is the proximal stimulus?
A) the tree
B) the light waves reflected by the tree
C) the image cast by the tree on the man's retina
D) the pattern of nerve impulses triggered by the retinal image and conducted by the optic nerve to the brain
Proximal Stimulus
The physical energy from a stimulus as it directly interacts with sensory receptors.
Retinal Image
The visual picture formed on the retina, the light-sensitive surface at the back of the eye, enabling sight.
Optic Nerve
A cranial nerve that transmits visual information from the retina to the brain.

Final Answer :
C
Explanation :
The proximal stimulus is the stimulus that directly impinges on an observer's sensory receptor cells. In this case, the tree is the distal stimulus (the object in the external world), but the image of the tree cast on the man's retina is the proximal stimulus.
