This document discusses the nature and types of perception. It defines perception as the process of receiving sensory information and making sense of one's environment. The perceptual process involves sensation, selection, organization, and interpretation of stimuli. Factors that influence perception include both subjective factors in the perceiver, like attitudes and expectations, as well as objective factors in the target, like size, motion, and proximity. The document outlines several types of perception, including form perception, size perception, motion perception, depth perception, and time perception.

3. NATURE OF PERCEPTION
“ 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”

4. The Perceptual Process
1.Sensation
 An individual’s ability to
detect stimuli in the
immediate
environment.
2.Selection
 The process a person
uses to eliminate some
of the stimuli that have
been sensed and to
retain others for further
processing.
3.Organization
 The process of placing
selected perceptual
stimuli into a
framework for
“storage.”
4.Translation
 The stage of the
perceptual process at
which stimuli are
interpreted and given
meaning.

7. We are required to perceive objects in different manners as
compared to their position in the environment.
Objects maybe moving or stationary when we have to
perceive motion. We may have to locate sounds and voices
in the space around us. We are also suppose to perceive
form, figure, depth and distance of objects.
Types of perception
1) Form perception
2) Size perception/ perception constancy
3) Motion perception
4) Depth perception
5) Time perception
TYPES OR KINDS OF PERCEPTION

8. FORM PERCEPTION
We do not perceive the world around us as
patches of colour, variation in bight-ness ,or
loud sounds and voices. Instead we see trees,
tables, buildings and cars; we hear automobile
horns, footsteps and words.
Perception is a unified experience. If we look at
a clock, for example, we don’t see parts, we
perceive the whole instrument that we
recognize as timepiece

9. TIME PERCEPTION
We often perceive time in our normal daily life. Perception of time is
less in children than in elders.
Time perception is a field of study
within psychology and neuroscience that refers to the subjective
experience of time, which is measured by someone's own
perception of the duration of the indefinite and continuous
unfolding of events. The perceived time interval between two
successive events is referred to as perceived duration. Another
person's perception of time cannot be directly experienced or
understood, but it can be objectively studied and inferred through a
number of scientific experiments.

10. DEPTH PERCEPTION
• Depth perception also acts as one of the types of
perception psychology. It relates to the way the human eye
identifies and contextualizes things in space.
• Depth perception is the visual ability to perceive the world
in three dimensions (3D) and the distance of an object.
• For instance, though the naked eye cannot see the end of a
tunnel, it interprets its possible depth through past
experiences such as scientific measurements to know how
deep the tunnel can be.
