Sensory, Attentional & Perceptual 
Processes
Knowing the world
Sense organs gather information from our 
environment and bodies.
Sensation is the detection and registration of this 
information.
Objects must capture our attention for sensation to 
occur.
Attention focuses on specific features like size, 
shape, and color.
The brain processes sensory input and assigns 
meaning.
Together, sensation and attention help us interpret 
our surroundings.

Nature and Varieties of Stimulus
Visual Stimuli
Examples include objects like a house. Visual stimuli are 
detected by our eyes, which are responsible for vision.
Auditory Stimuli
Examples include sounds such as music. These stimuli 
are detected by our ears, which are responsible for 
hearing.
Olfactory Stimuli
Examples include scents such as the fragrance of a 
flower. These stimuli are detected by our nose, which is 
responsible for the sense of smell.

More Varieties of Stimulus
Gustatory Stimuli
Examples include tastes like sweets. 
These stimuli are detected by our 
tongue, which is responsible for the 
sense of taste.
Tactile Stimuli
Examples include sensations such as 
the softness of a cloth. These stimuli 
are detected by our skin, which is 
responsible for the sensations of 
touch, warmth, cold, and pain.

Specialized Sense Organs
Humans are equipped with seven specialized sense organs, known as sensory receptors or information-
gathering systems, because they receive and gather information from various sources:
Eyes: For vision Ears: For hearing Nose: For smell
Tongue: For taste Skin: For touch, warmth, cold, 
and pain
Kinesthetic System: Provides 
information about body 
position and the movement of 
body parts relative to each 
other
Vestibular System: Provides information about balance and spatial orientation
