PERCEPTION is our brain’s attempt to interpret sensory information—but it's not
always accurate. Errors in perception can occur due to defects in sense organs,
brain processing, or external interference like bias, distraction, unclear stimuli, or
inner conflict. These errors include:
ILLUSIONS VS. HALLUCINATIONS
- Illusions involve misinterpreting real stimuli. For instance, in dim light, a rope
may be mistaken for a snake, or a distant stranger may be seen as someone
familiar. These errors occur across all senses but are most familiar visually and
auditorily .
- Hallucinations are perceptions without any real stimulus—seeing or hearing
things that aren’t there. These can be visual, auditory, tactile, olfactory, or
multisensory and are often associated with mental illness, extreme emotional
states, or intoxication.
Additionally, sensory anomalies like anesthesia (no sensation), hyperesthesia
(excessive sensitivity), and paresthesia (distorted touch) affect tactile
perception—adding further complexity to how we experience the world.
COMMON VISUAL ILLUSIONS
- Müller-Lyer illusion: Equal lines appear unequal due to arrow-like end shapes.
- Ponzo illusion: Objects positioned between converging lines (like train tracks)
look larger the higher they are along the perspective lines.
