Key Difference: Both the words Perception and Conception are nouns derived from two different verbs Perceive and Conceive. The main difference between the two words is that Perception is trying to understand or becoming aware of something through the senses, experiences or expectations. While, Conception means an image or an idea, or notion formed in the mind, which is also called as concept or the ability to form something in the mind and to develop an understanding.

Perception:

 How a person perceives a specific event or thing depends upon mental ability and experience and is different from other person's experience. Thus the perception changes from person to person. Perception is also shaped by the person's learning, memory, expectation and attention. Perception is understanding of something experienced through the senses like for an example through hearing (ear) about a person, the mind can change the perception or the image based on whatever was earlier heard.

Eg: I thought XYZ is a good school, but when I heard about their latest scandal, I will re-think about the admission in the school. So, this means that the person's perception about the school was changed after hearing about a certain scandal related to the school. The original image of the school was good because that person was thinking to get enrolled in that school, but later changed the mind because of certain knowledge about school. All perception involves signal that goes to the person's nervous system , that results in chemical or physical stimulation of the sensory system. For example, vision involves light striking the retina of the eye or hearing involves pressure waves. Perception are often based on feelings, intuitions, dreams, analysis, discussions and sometimes may not result more than awareness.
