Perceptual Threshold: The perceptual threshold is the minimum amount of stimulation necessary for a stimulus to be detected. It determines whether or not we can perceive certain visual sensations.

Sensory Adaptation:

Sensory adaptation is the diminishing sensitivity to an unchanging stimulus over time. It allows us to focus on important changes in our environment instead of being overwhelmed by constant sensory input.

Selective Attention:

Selective attention refers to focusing on specific stimuli while ignoring others. It helps us filter out irrelevant information and concentrate on what is important at any given moment.
