Sensation mcq (Jyosilpsycho-hub)


Sensation is the input about the physical world obtained by our sensory receptors, and sensation is the process by which the brain selects, organizes and interprets these sensations. A sensation is the simplest cognition. It is a simple impression produced in the mind by a stimulus. The stimulus acts upon a sense-organ or the peripheral extremity of a sensory nerve; the impression or nerve-excitation is conducted by the sensory nerve to a sensory centre in the brain; then, sensation is produced in the mind. This is the case with sensations of colours, sounds, tastes, smells, heat, cold, etc Stimuli are either external to the organism or within the organism. They are neither extra-organic or intra-organic Organic sensations of hunger, thirst, fatigue, headache, etc. are produced by the internal conditions of the organism. They have no special sense-organs. Sensations are simple impressions of some qualities. But their meanings are not known. As soon as their meanings are interpreted, they become perceptions.
