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.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

4. The process by which sensory information is
actively organized and interpreted by the brain
The process of selecting, organizing, and
interpreting raw sensory data into useful mental
representations of the world.
Perception:
6. Subjective factor are related to the perceiver's own
self. There are stated as the internal state or
psychological state.
Some subjective are:
Fitness.
Interest.
Past experience and Knowledge.
Mantel Capacity.
Subjective Factor:
7. Objective factor are found in the physical
environment know as stimuli. There stimuli are so strong
that an individual is attracted to attend to them and
perceive them.
Objective factor:
8. Social factor are related to need and interest of the
group in society to which an individual belongs. Men is a
social animal. He cant live alone
Social value.
Attitudes.
Stereotype.
Suggestion.
Social Factor:
9. There are five kinds of perception
These are:
Form Perception.
Perception of Movement.
Depth perception.
Time Perception.
Kinds of Perception:
10. Perception depends on sensory information's. On
the base of these information, different forms and
patterns are perceived.
According to wood worth, perceptual organization
is based on two thinks:
Figure
Ground
Form Perception:
15. Law of Proximity or Nearness.
Law of Similarity.
Law of Good from or figure.
Law Of Perceptual Organizations:
16. Proximity means nearness. According to this law,
the things situated nearer to each other; form a figure or
a pattern and are perceived as a whole figure. This
proximity may be in space and time. If different words are
set nearer to each other, they form an organization.
Consequently, we perceive them in a moment. As it is
evident from the following figure
Laws of Nearness or proximity:
17. Our brain see objects near each other as groups.
Laws of proximity:
18. Law of similarity or likeness is the perceptual tendency to
group together similar elements. If different objects are similar in
shape, we classify them in a group; and perceive accordingly as
shown in fig:
Law of similarity or Likeness:
19. In the law of good form, the stimuli having stimuli
having similar ship are grouped together. This group[
may b of five types
Good Continuation
Symmetry
Closure
Common Direction
Inclusiveness
Law of Good Form:
20. The perceptual tendency to see all the parts of a
figure in “one whole” is called the whole good
continuation. It make a picture of the grouping
organization.
Good Continuation:
21. A symmetrical figure makes a perceptual
organization and perceived sooner.
In the following figures we perceived circles, areas
and lines as a single unit when uniformed and linked.
Symmetry:
22. It is our perceptual tendency to fill the gaps or
closure fills the gaps in perceptual organization to help us
to perceive it as a whole complete form, for example the
following incomplete circle
Closure:
23. When the stimuli are presented in a straight line or
a semi-circle form, their grouping in the perceptual
organization is classified in two groups because of their
common direction, for example
Common Direction:
24. Sometimes all the stimuli are include to form a
pattern.
Due to this inclusiveness in the following lines of similar
pattern.
Inclusiveness:
25. Movement or Motion is perceived by following the
progressive change of an object’s position in space with time.
It has two types
Real Movement:
Apparent Movement:
Perception of Movement:
26. Real Movement:
The perception of the actual movement of objects
in the world is termed as “real motion/movement
“perception”.
Apparent Movement:
It is movement perceived in the absence of
physical movement of an image across the retina. This
can be produced by a rapid succession of motionless
stimuli that minimize the changes that occur in real
movement.
28. The ability to view the world in three dimensions
and to perceive distance is known as depth perception.
“This ability helps to perceive three dimensional space
and to accurately judge distance”
Depth Perception:
29.
30. We perceive time in, seconds, minutes, and hours
which pass into days weeks months and in years and even
in centuries. Time is perceived in terms of Past, Present,
and Future Perception of time is less in children than
elders Several factors influence time perception: Subjective
(age, activity, motivation, intelligence) Objective:
Time Perception:
31. Three types of constancy are explained briefly
here:
Size Constancy
Shape Constancy
Color Constancy
Type of Perceptual Constancy:
32. Size constancy is the tendency to perceive objects
in a consistent manner despite the changing sensations
that are received by our senses. visual constancy plays an
important role in helping us adapt to our environment
successfully.
Size Constancy:
34. When we know that the object is a certain
shape ,we tend to perceive it as the same shape,
regardless of the viewing angle. We have learned
to make corrections in our perception dependent
on the angle from which we observe
Shape Constancy:
37. Colors of objects tend to remain constant in
perception when we know their true color. Visual
objects also appear constant in their degree of
whiteness, grayness and blackness.
Color Constancy:
38. 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.
Illusion:
39. Physical causes.
Habit & Familiarity.
Expectancy & Mental Set.
Momentary State of Mind or Mood.
Incomplete analysis of the collective impression.
Apperception.
Suggestion.
Arrangement of stimuli.
Causes of Illusion:
40. There are two type of illusion:
Illusion Of motion.
The Illusion Of forms.
Type of Illusion:
41. When a stationary stimulus is perceive as moving,
it is named as illusion of motion or movement.
Illusion Of motion.
42. The Illusion of Phi-phenomenon.
The Illusion of Stroboscope.
The Illusion of Gama phenomenon.
The Illusion of Delta motion.
The Illusion of Auto-Kinetic.
The Illusion of Induced movement.
The Illusion of negative after image of movement.
Types of Illusion of motion:
43. Form perception is attained in relation to the
figure and ground according to the law of perception
Organization. As the figure is smaller then the ground
according to perceptual.
The Illusion of form:
44. The illusion of distance occurs when the parallel
lines seem to bend in different directions.
The Illusion of distance:
45. Psychologists have fail to understand this illusion. It
seem that the curving line behind the spiral have become the
cause of this illusion. The illusion is also known as the false
spiral, or by its original name, the twisted cord illusion.
Spiral circle illusion:
46. The parallel lines seem to bend to each other
instead of looking straight. The reason of this Illusion is
the smaller diagonal lines cutting the parallel line.
The Zollner Illusion:
47. If two parallel line are dissected by another
straight line separately, a large straight line seem cutting
the parallel line instead of two partial line.
The Poggindorf’s Illusion:
48. The Herring illusion can also be induced by a
background of optic flow. It is two horizontal line are
cure by the line of different direction, will not look
parallel. The distance between the two lines looks greater
where the lines assemble from different direction as is
found in fig
Herring’s Illusion:
49. A near object is near usually perceived larger and
farther object is perceived smaller but in the moon
illusion, moon is perceived larger on horizon where the
earth and sky seem to meet.
The Illusion of size:
