Fanny's photoreceptors detect light and dark stimuli. Cortical processing then allows her to recognize the words in her psychology textbook. As she reads, Fanny relates the information to her own experiences. Fanny's recognition of the words illustrates _. When she relates the information to her experiences, Fanny is demonstrating _.

A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.

Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes.

Cerebral cortex is mainly responsible for various bodily functions such as movement, processing information from the five senses, comprehension of messages (informations) and the ability to understand. It is a thin layer found in the brain that is responsible for covering the outer portion or part (about 1.5mm to 5mm) of the cerebrum.

Generally, the cerebral cortex is also referred to as gray matter and it's mainly covered by the meninges.

A photoreceptor can be defined as a specialized cells or neuron found in the eye's retina that are able to detect and react to light.

Perception refers to the ability of an individual to see, hear, and take cognizance of sensory informations through the senses.

On the other hand, cognition is the ability of an individual to understand or interpret sensory informations through thought and the senses.

In conclusion, Fanny's recognition of the words illustrates perception while cognition involves the process of relating the information to her experiences.
