Perception

Perception can be defined as our recognition and interpretation of sensory information.

Perception also includes how we respond to the information. We can think of perception as
a process where we take in sensory information from our environment and use that
information in order to interact with our environment. Perception allows us to take the
sensory information in and make it into something meaningful.

Perception is also necessary for us to survive in our environment. For example, before
parents feed their babies milk; they taste it in order to make sure that the temperature isn't
too hot. This involves using sensory information (touch and taste) to make sure that the food
is not dangerous for the infant. Before we cross a busy street, we rely on our hearing and
sight to make sure a car is not coming. Without the sensory information, we would not be
able to judge which food was too hot or when an appropriate time to cross the street would
be, which could put us and our children in danger.

Definitions
"The study of perception is concerned with identifying the process through which we
interpret and organize sensory information to produce our conscious experience of objects
and object relationship."
“Perception is the process of receiving information about and making sense of the world
around us. It involves deciding which information to notice, how to categorize this
information and how to interpret it within the framework of existing knowledge.”
“A process by which individuals organize and interpret their sensory impressions in order to
give meaning to their environment.”
"Perception is a complex cognitive process this is concerned with selection, organization and
interpretation of stimuli."

The Perceptual Process

The perceptual process involves a series of steps that our brain takes to interpret and make
sense of the sensory information received from the environment. This process transforms raw
sensory input into meaningful patterns and experiences. Here’s an overview of the key stages
of the perceptual process:

1
1. Sensory Stimulation (Exposure)
The process begins with the exposure to a stimulus from the environment. This can be
anything that activates one or more of our sensory receptors—like seeing a bright light,
hearing a sound, smelling a fragrance, tasting food, or feeling a texture.
2. Attention
Out of all the stimuli that we are exposed to, only a limited amount captures our attention.
Attention is selective; it determines which stimuli we focus on while filtering out others . This
selection is influenced by factors like intensity, novelty, relevance, and personal interest.
3. Sensation
The sensory receptors in our eyes, ears, nose, skin, and mouth detect the stimuli and convert
them into neural signals. Sensation is the immediate and direct response of these receptors to
the stimulus. For example, when light enters the eye, the photoreceptors in the retina detect it
and send signals to the brain.
4. Perceptual Organization
The brain organizes the sensory input into recognizable patterns. Perceptual organization
involves processes like:
Grouping: Combining similar or related elements together.
Figure-Ground Relationship: Distinguishing an object (figure) from its background (ground).
Closure: Filling in gaps to perceive a complete, whole object even when parts are missing.
Proximity and Similarity: Perceiving elements that are close to each other or similar as
belonging together.
5. Interpretation
Once organized, the brain interprets the information to give it meaning. Interpretation
involves assigning meaning based on past experiences, expectations, culture, and personal
biases. For instance, the same facial expression might be interpreted as friendly or hostile
depending on one’s experiences or cultural background.
6. Memory
The perceived information is then stored in memory, where it can be retrieved later for
decision-making, judgment, or future recognition. Memory also plays a role in helping us
recognize familiar objects, faces, sounds, and other stimuli.
7. Response
Based on the perception, a person may take action or react to the stimulus. The response
could be a physical action (like moving away from danger) or a psychological response (like
2
feeling happy or anxious). The response is informed by both the interpretation and the
emotional reaction to the perceived stimulus.
8. Feedback Loop
The perceptual process often involves a feedback loop. The outcome of a perception can
influence future perceptions and expectations. For instance, if someone perceives a situation
as dangerous and it turns out to be safe, their future perception of similar situations might be
less cautious.

FACTORS INFLUENCING PERCEPTION

A) Subjective Factors/Factors in the perceiver

1. Attitudes: It refers to an individual's predisposition or tendency to respond positively
or negatively toward a certain idea, object, person, or situation. Attitudes are formed
through experiences, cultural influences, education, and social interactions.
2. Motives: Our goals and needs influence what we focus on and how we interpret
information. For instance, when hungry, a person might be more likely to notice food-
related cues in their environment.
3. Personality Traits: Individual personality traits, such as openness, conscientiousness,
or neuroticism, can influence perception. For example, a highly conscientious person
might be more detail-oriented in how they interpret their environment.
4. Interests: Interest is a key factor influencing perception because it determines what
we pay attention to and how we interpret the information we receive. Our interests
shape the way we focus on and process sensory input, making certain details more
noticeable and relevant while filtering out others that seem less important.
5. Experience: Previous encounters and learned experiences can shape how we perceive
new information. For example, someone who has had negative experiences with dogs
might perceive them as threatening, while someone with positive experiences may see
them as friendly.
6. Expectations: Pre-existing beliefs and expectations create a perceptual set, priming
us to perceive things in line with what we expect. This can lead to confirmation bias,
where we only notice information that aligns with our beliefs.

 7. Emotions and Mood: Our current emotional state can heavily influence perception.
If someone is feeling anxious, they might interpret neutral expressions as threatening.
Conversely, a positive mood can lead to more optimistic interpretations.

B) Objective factors/Factors in the Target

1. Novelty and Familiarity: Unusual or novel stimuli tend to stand out and are more
likely to be perceived. At the same time, familiar stimuli are easily recognized and
processed quickly. A new or unexpected sound is more likely to grab attention than
something that is common and expected.
2. Motion: Moving objects are more likely to capture attention than stationary ones. For
instance, a moving car is more easily noticed than a parked one, and motion in the
periphery of vision tends to draw attention.
3. Sounds: Sound is often a primary means of drawing attention. Sudden or loud sounds
(like alarms, sirens, or a shout) can immediately capture focus, triggering quick
reactions. The brain is wired to respond to auditory stimuli as a survival mechanism,
making sound crucial in perception. Sound provides important cues about our
surroundings. For example, the sound of footsteps can inform us of someone’s
approach, and the hum of traffic can provide context for where we are. Different
environments have distinct soundscapes that help us orient ourselves, even without
visual input.
4. Size: Larger objects or stimuli are more easily noticed and perceived than smaller
ones. For instance, a large billboard is more likely to catch a person’s attention than a
small sign.
5. Background: Background as a factor of perception refers to the contextual elements
surrounding a stimulus that influence how it is perceived. The background provides a
frame of reference, impacting how we interpret, focus on, or understand the main
object or event. The context in which a stimulus is presented heavily impacts its
interpretation. For instance, the same facial expression can be interpreted as friendly
or sarcastic depending on the surrounding environment, tone of conversation, or
social setting.
6. Proximity and Grouping: Stimuli that are close to each other or grouped together
tend to be perceived as related or belonging together. For example, in visual
perception, objects that are close together are often seen as a single group.

4
 7. Similarity: Similarity is a crucial factor in perception, especially in how we organize
and interpret sensory information. According to the Gestalt principles of perception,
similarity refers to the tendency of our minds to group together elements that are alike
in some way. The principle of similarity suggests that we naturally group objects that
are similar in appearance, such as those that share the same shape, colour, size, or
texture. For example, if you see a pattern of circles and squares, you are more likely
to group the circles together and the squares together based on their shared features.

C) Social or cultural factors

1. Social Influences: Group norms and peer opinions can shape individual perception,
sometimes leading people to conform to a collective viewpoint.
2. Cultural Background: Cultural norms and values affect perception. Different
cultures may emphasize different aspects of reality, leading people from distinct
backgrounds to perceive the same situation in varied ways.
3. Prejudice: Prejudice is a powerful subjective factor that significantly influences
perception. It involves preconceived opinions or biases that are not based on actual
experience or reason. Prejudices can distort how we perceive people, events, or
situations, often leading to unfair or inaccurate judgments. Prejudice leads to selective
perception, where a person notices and remembers information that confirms their
biased beliefs while ignoring or dismissing information that contradicts those beliefs.
This selective focus reinforces existing prejudices, making it difficult to perceive
reality accurately.

NATURE OF PERCEPTION
1. Perception is the process by which an individual gives meaning to the environment.
2. It is a cognitive and psychological process.
3. People's action, emotions, thoughts and feelings are triggered by their perceptions.
4. Since perception refers to the acquisition of specific knowledge about objects or
events at any moment, it occurs whenever stimuli activate the sense organs.
5. Though perception has been defined in a variety of ways, it basically refers to the way
a person experiences the world.
6. Perception is an almost automatic process and works in much the same way within
everyone, yet typically yields different perceptions.
7. A stimulus that is not perceived has no effect on behaviour.
8. Perception is a process that operates constantly between us and reality.
9. Since perception is subjective process, different people may perceive the same
environment differently. So, perception is like beauty, that lies in the eyes of the
beholder.
10. Perception involves the creation of gestalts.
11. Perception is a unique interpretation of the situation, not an exact recording of the
situation.
12. Perception is more complex and much broader than sensation.
