Answer:
The correct answer will be -
1. Sensation
2. Perception
Explanation:
The sensation is the process of detecting the external stimuli and internal by sensory receptors.
The sensory receptors convert the stimuli to the action potential or electric impulse which is then transferred to the specific part of the brain where the stimuli are perceived.
Perception is the process of receiving, organizing, analyzing or interpreting the received stimuli and understanding the environment. The main organ which receives the stimuli is the thalamus which perceives the sensory impulses and sends it to the specific part of the brain.
Thus, Sensation and Perception are correct processes.
