What to Focus On
- Sensation is the basic experience arising from excitation of sense organs sent to the brain
- Receptors are classified as External, Body, and Internal receptors
- Visual sensation: Light → Pupil → Vitreous Humor → Retina → Brain (via optic nerve)
- Attention is selective mental concentration on chosen stimuli from many available ones
- Garrett: 'Attention is selection and concentration on a definite stimulus'
- Drever: 'Attention is mental concentration on selected stimuli'
- Determinants of attention are divided into Objective (External) and Subjective (Internal) factors
- Objective factors: Intensity, Size, Contrast, Motion, Change, Novelty, Repetition, Colour
- Subjective factors: Interest, Need, Habit, Learning, Physical and Mental State
Common Mistakes to Avoid
Sensation and Perception are the same process — if you sense something, you automatically perceive it.
Attention means paying equal focus to everything in the environment at the same time.
Monocular cues only work when one eye is physically closed or absent.
