Explanation:

Sensation is basically a response of a sensory receptor to external stimuli, ie it is a physiological response of the organism. It is a process in which the human senses convert the energy of a stimulus into neural messages and elicit reactions.

Perception, on the other hand, is the judgment given by the subject based on the information of the sensations. It is the individual's interpretation of what has been captured by the senses. It is a process that can be influenced by physiological and psychological factors as well as external issues such as cultural and social aspects.

Thus, we can state that detecting black marks on a page depends on the sensation process, and the ability to interpret black lines and curves as letters and words involves the process of perception.
