Psychology - Sensation and Perception
- Sensation
- Initial process of detecting and encoding environmental energy
- Sensation is the same for every person
- Sense organs are involved
- Physiological response
- Perception
- Organising, interpreting and giving meaning to what the sense organs initially process
- Perception differs from person to person
- The brain is involved
- Psychological response
- Process - Vision
- 1. Reception
- Light reflects off the visual stimulus and enters the eye through the pupil and is detected by the retina
- 2. Transduction
- Photoreceptors (rods and cones) convert electromagnetic energy into electrochemical energy
- 3. Transmission
- The sensory information is sent from the eye to the brain via the optic nerve to the primary visual cortex via the thalamus
- 4. Interpretation
- The brain assigns meaning to the original stimulus to understand what is being seen
- Process - Taste
- 1. Reception
- Chemical molecules in food are broken down by saliva and detected by the taste receptors
- 2. Transduction
- Taste receptors convert chemical molecules into electrochemical energy
- 3. Transmission
- The sensory information is sent from the tongue to the brain via the facial nerve to the primary gustatory cortex via the thalamus
- 4. Interpretation
- The brain assigns meaning to the original stimulus to understand what is being tasted
