This PPT contains Perception from Unit 3 Cognitive Process of the subject Psychology for F.Y.B.Sc. Nursing.
Perception is a fundamental cognitive process that involves interpreting and making sense of sensory information received from the environment. It's how we organize and interpret what we see, hear, feel, taste, and smell, allowing us to create a meaningful understanding of the world around us. Perception plays a crucial role in shaping our thoughts, behaviors, and interactions with the external world.
Perception: The process by which sensory information is actively organized and interpreted by the brain.
Factors of Perception.
Kinds of Perception
Laws of Perceptual Organisation
Types of Perceptual Constancy
Illusion:Something that looks or seems different from what it is something that is false or not real but that seems to be true or real.

Chapter 6: Perception
Selective Attention
At any moment we are conscious of a very limited amount of all that we are capable of experiencing. One example of this selective attention is the cocktail party effect—attending to only one voice among many. Another example is inattentional blindness, which refers to our blocking of a brief visual interruption when focusing on other sights.
Perceptual Illusions
Visual and auditory illusions were fascinating scientists even as psychology emerged. Explaining illusions required an understanding of how we transform sensations into meaningful perceptions, so the study of perception became one of psychology’s first concerns. Conflict between visual and other sensory information is usually resolved with the mind’s accepting the visual data, a tendency known as visual capture.
Perceptual Organization
From a top-down perspective, we see how we transform sensory information into meaningful perceptions when we are aided by knowledge and expectations.
The early Gestalt psychologists were impressed with the seemingly innate way we organize fragmentary sensory data into whole perceptions. Our minds structure the information that comes to us in several demonstrable ways:
Form Perception
To recognize an object, we must first perceive it (see it as a figure) as distinct from its surroundings (the ground). We must also organize the figure into a meaningful form. Several Gestalt principles—proximity, similarity, continuity, connectedness, and closure—describe this process.
Depth Perception
Research on the visual cliff revealed that many species perceive the world in three dimensions at, or very soon after, birth. We transform two-dimensional retinal images into three-dimensional perceptions by using binocular cues, such as retinal disparity, and monocular cues, such as the relative sizes of objects.
Motion Perception
Our brain computes motion as objects move across or toward the retina. Large objects appear to move more slowly than smaller objects. A quick succession of images, as in a motion picture or on a lighted sign, can also create an illusion of movement.
Perceptual Constancy
Having perceived an object as a coherent figure and having located it in space, how then do we recognize it—despite the varying images that it may cast on our retinas? Size, shape, and lightness constancies describe how objects appear to have unchanging characteristics regardless of their distance, shape, or motion. These constancies explain several of the well-known visual illusions. For example, familiarity with the size-distance relationships in a carpentered world of rectangular shapes makes people more susceptible to the Müller-Lyer illusion.
Perceptual Interpretation
The most direct tests of the nature-nurture issue come from experiments that modify human perceptions.
Sensory Deprivation and Restored Vision
For many species, infancy is a critical period during which experience must activate the brain’s innate visual mechanisms. If cataract removal restores eyesight to adults who were blind from birth, they remain unable to perceive the world normally. Generally, they can distinguish figure from ground and can perceive colors, but they are unable to recognize shapes and forms. In controlled experiments, animals have been reared with severely restricted visual input. When their visual exposure is returned to normal, they, too, suffer enduring visual handicaps.
Perceptual Adaptation
Human vision is remarkably adaptable. Given glasses that shift the world slightly to the left or right, or even turn it upside down, people manage to adapt their movements and, with practice, to move about with ease.
Perceptual Set
Clear evidence that perception is influenced by our experience—our learned assumptions and beliefs—as well as by sensory input comes from the many demonstrations of perceptual set and context effects. The schemas we have learned help us to interpret otherwise ambiguous stimu

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
1. - determine how objects
are organized into groups
and then perceived as such.
2. - emphasizes nature of perception
and this are different ways to perceive
things. Some gestalt theories to cause
objects to grouped together are
similarity, nearness or proximity, and
continuity.
3. In the principle of similarity we
tend to perceive things like or similar
elements belonging together.
Examples:
4. In the principle of proximity or
nearness, we tend to group together
elements that are near to each other and
perceive them as one.

5. The law of continuity states that people
have tendency to group stimuli into continuous
lines and patterns.
Example:
6. - is a type of perceptual
grouping which is vital
necessity for recognizing
objects through vision.
In Gestalt Psychology it
is known as the figure
from the background.
Note: We can separate the form from the ground
because of contour. A Contour is the boundary of
perceptual figure.
7. – misinterpretation of exterior visual
stimulants which takes place as an
outcome of either pathological condition
or a misperception of the stimulants.
Misrepresentation of spatial figures such
as the Muller-Lyer Illusion, Poggendorf
Illusion, and Zollner Illusion.
9. - an apparent
deflection of a
straight line when
it is interrupted by
two lines parallel
to each other.
10. – an illusion of visual
space perception in
which two parallel
lines intersected by
numerous short
diagonal lines slanting
in the opposite
direction seem to
diverge.
