3.  Any experience that takes place through a sense organ is
called Sensation.
 Sensation is also called as the gate ways of knowledge,
because all our knowledge is based upon the functioning of
sense organs.
 Sensation is the simple and most elementary process,
which creates the desire to work for something and how to
know something based on previous experiences.
 It is purely sensory knowledge, which does not have any
relationship with any knowledge or awareness.
A sensation does not help us acquiring complete knowledge.

4.  The impressions received through the sense
organs are called sensations – Mathur.
 A Sensations are first things in the way of
consciousness – James.
 Sensation is defined as the simplest of all
conscious experience – Duglas and Halland.
 Ssensation is the process of receiving,
translating and transmitting information to
the brain from the external and internal
environment – Huffman.

5. We can divide easily the sensation process into
five categories on the basis of sense organs.
 Visual Sensation
 Aauditory Sensation
 Olfactory Sensation
 Taste Sensation
 Tactual Sensation

6.  The eye is the organ of our sensation of sight. It occupies the
first place among the sense-organs and is called “the queen
of senses”.
 The stimulus for the visuall sensation is rays of light.
 The light-enter the eye through cornea. After passingg
through the pupil and the lenses they reach retina: From the
retiria the optic nerve carries the visual impulse to the brain,
and we have the sensation of sight.
 The visual sensation occupies the highest place among
sensations. It is the most refined sensation.
 It is important to mark two stages in the development, of
sight sensation.
 These are Brightness sensations and Colour sensations.
 White, Black and Grey are brightness sensations and belong to
the most primitive and earliest sensations.
 The colour sensations are those of blue; green, red and
yellow. They come at a later stage in the development of the
eye.

7.  The ear is the organ of our-auditory sensations. The
stimulus for sound sensation consists of the vibration
or motion in the particles of air.
 The ear consists of three parts :
 (i) The external ear: It collects the sound waves
which are carried by the auditory canal to the
central brain.
 (ii) The middle ear: It is a drum-shaped cavity from
where certain bones oscillate and produce vibrations
in the ear.
 (iii) The inner ear: It sends nerve impulse to the
brain-where the sensation arises.

8.  The nose is the organ of smell. The appropriate
stimuli for the sensation of smell-are the gaseous
substances included in the air.
 The olfactory nerve in the upper cavity of the nose
plays an active role in smell sensation.
 The olfactory nerve carries the odorous impulse to
the brain where brain where the sensation of smell
takes place.
 The important points to be noted about smell
sensation are:
1. The sensation of smell is useful in order to know
the kind of surroundings we are placed in.
2. The sensation of smell is connected with the
sensation of taste. We can judge the taste of a
thing by smelling its oders

9.  The tongue is the organ of taste. The sensation
of taste can be stimulated only by fluids.
 Solid objects must first dissolve themselves
before they can produce any taste sensation.
 At the back of the tongue there are taste bulbs
or ‘taste buds’ each of which contains a number
of taste cells.
 When we put anything on the tongue, its
particles come in contact with these cells, and
the sensation is caused Thus, the ‘taste buds are
the receptors of stimuli.
 There are only four basic tastes : sweet, bitter,
sour, and selfish.

10.  The main elements of the sensation process are given below:
 Quality: The nature of each sensation is different from other. Every
type of sensation has got its own special quality or characteristics.
This quality of the sensation helps us to distinguish one from other.
For example, green sensation of eye, cold sensation of skin.
 Intensity: Sensation differs in respect of its intensity. If two sounds
are created at once, one will be the intenser than other. It is differs
in same type of sense or among the different types of sensations.
 Extensity: Extensity refers the extension in space. Each
sensation has its extensity. The vaster the stimulus, the more
extensive the sensation. The extensity is not true for all the
types of sensation, but restricted to certain.
 Duration: Every sensation has its duration or lasts for certain
time. The auditory sensation of aero plane sound is more
extensive than the sound of the calling bell.
 Clarity: Every sensation has got clarity. The sensation which
lasts for longer period becomes clearer than the sensation
lasts for shorter period.

11.  Our sensory organs react to the environment.
our brain interprets sensory information. Our
impressive sensory ability allow us to
experience the most enjoyable and most
miserable experiences, as well as everything
in between , our eyes, ears, nose, tongue
and skin provide an interface for the brain to
interact with the world around us.
