Perception is the process by which the brain selects, organizes, and interprets sensations; it is often influenced by
learning, memory, emotions, and expectations
. The human senses include sight, sound, taste, smell, and touch, as well as kinesthesia and the vestibular senses.
What are some examples of sensation and perception?
For example, upon walking into a kitchen
and smelling the scent of baking cinnamon rolls
, the sensation is the scent receptors detecting the odor of cinnamon, but the perception may be “Mmm, this smells like the bread Grandma used to bake when the family gathered for holidays.”
What can affect sensory perception?
Health problems
, such as a lack of certain nutrients, can also cause sensation changes. Brain surgery, problems in the brain, confusion, and nerve damage from injury or long-term (chronic) diseases such as diabetes can also result in sensation changes.
How does sensation and perception affect behavior?
How is ‘sensation and perception’ involved in behaviour? We need the combined input from our senses to tell us about what is happening in the world around us.
The brain perceives and uses lots of information to work out if and when to do something in response
: to act or behave.
What are the factors affecting sensation and perception?
Sensory adaptation, selective attention, and signal detection theory can help explain what is perceived and what is not. In addition, our perceptions are affected by a number of factors, including
beliefs, values, prejudices, culture, and life experiences
.
What are factors affecting sensation?
- Sensation is input about the physical world registered by our sensory receptors, such as our eyes, ears, mouth, nose, and skin.

What are the types of sensation?
Broadly, these sensations can classify into two categories. First, general sensations which include
touch, pain, temperature, proprioception, and pressure
. Vision, hearing, taste, and smell are special senses which convey sensations to the brain through cranial nerves.
What is an example of top-down processing?
One classic example of top-down processing in action is a phenomenon known as
the Stroop effect
. In this task, people are shown a list of words printed in different colors. They’re then asked to name the ink color, rather than the word itself.
What are the main causes of sensory loss?
- age-related hearing loss.
- genetic conditions, such as Usher syndrome.
- an infection in a baby in the womb, such as rubella (German measles)
- cerebral palsy – a problem with the brain and nervous system that mainly affects movement and co-ordination.
How do emotions affect perception?
Cognitive processing is needed to elicit emotional responses. At the same time, emotional responses modulate and guide cognition to enable adaptive responses to the environment. Emotion
determines how we perceive our world, organise our memory, and make important decisions
.
What are the major types of perceptual problems?
- drawing objects.
- recognising objects (agnosia)
- telling left from right.
- mathematics (discalculia)
- analysing and remembering visual information.
- manipulating or constructing objects.
- awareness of the body in space (e.g. climbing stairs)
- perception of the environment (e.g. following directions).
How does attention affect our perception?
Think of attention as a highlighter. … Not only does our attentional system allow us to focus on something specific in our environment while tuning out irrelevant details, but it also affects
our perception of the stimuli surrounding
us.
What are the basic principles of sensation and perception?
Summary. Sensation occurs when sensory receptors detect sensory
stimuli
. Perception involves the organization, interpretation, and conscious experience of those sensations.
How does sensation affect you in everyday life?
Humans possess powerful sensory capacities that allow us to sense the kaleidoscope of sights, sounds, smells, and tastes that surround us. Our eyes detect light energy and our ears pick up sound waves. Our
skin senses touch, pressure, hot, and cold
.
