SENSATION

SENSATION

• Sensation is the indefinite generalized body feeling

• The faculty to feel or perceive physical sensibility

• A perception associated with stimulation of a sense organ or with a specific body condition

• “Sensation are elementary impression about the external world gathered by sense organs.It is merely awareness of the bare quality of experience and arises directly from the stimulation of a sense organs.”

NATURE OF SENSATION

• Sensation is the simplest form of cognition• Sensation is the elementary raw material of our

knowledge• Sensation is the simplest form of mental activity• It is orginated from the sense organs• A sensation is an inner experience aroused by

the respective stimulus through sense organs• The bare awareness of a sensory quality like

sound,colour,odour or taste is a sensation.

TYPES OF SENSATION

SENSATION

Organic sensation

Motor /kinaesthetic

sensation

Special sensation

It is produced by internal organs.Eg. Hunger, thirst

These are produced by

changes in the organs of

movement viz , muscles, tendons,

and joints

These are produced by special kinds of

stimuli like light waves, air waves and

so on. Colour , sounds, taste, smell, pressure, heat, cold

etc are special sensation

ATTRIBUTES OF SENSATION

Attributes of

sensation

Quality

Intensity

Extensity

Duration

Localisation

1.Quality:-These are produced by different kind of stimuli and they have different sense organs.

Eg: Sensation of sound are produced by air on the ear

2. Intensity:-all sensation differ in intensity and vary from weak to very intensive nature

Eg: a white a faint sound produces a faint sensation of light

3.Extensity :- It is depends upon the area of the sensitive surface stimulated by a stimulas .

Eg: Touch a book with a finger tip and then with your palm the first tactual sensation has greater extensity than the second one .

4.Duration:- * every sensation has a sensible duration * a sensation may linger in the mind for a shorter

or longer duration * a sensation may last longer than its stimulus

causing after sensation .* It is specially noticable in case of vision

5. Localisation :-It is distinguishes a sensation of one part of a sense organ form an identical sensation of another part

LAWS OF SENSATION

SIMILARITY PROXIMITY CLOSURE CONTINUITY

This law states that elements of

a stimulus configuration will

be grouped together

perceptually if they are similar to each other

This law states that elements nearer to each

other are perceived as

part of the same configuration

The law states that we tend to close the open

edges of a figure to make the

stimulus configuration

complete.

The law states that we link individual

elements of a configuration so that they form

continuous pattern that makes sense

to us.

FACTORS OF SENSATION

*GOOD HEALTH *PEACE AND QUIET * LOVE *JOY *DREAMS *PRESSURE *TEMPARATURE *SMELL
