AP PSYCHOLOGY

Detailed explanation-1: -Sensation = the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. Perception = the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events.

Detailed explanation-2: -Sensory receptors are specialised to perceive a certain kind of stimulus. When they receive the stimulus, they convert the energy from stimulus to electric signals. The electric signal, action potential or impulses thus generated are transmitted by sensory neurons or afferent neurons to the brain and spinal cord.

Detailed explanation-3: -Sensation is the process of receiving stimulus energies from the external environment and transforming those energies into neural energy.

Detailed explanation-4: -According to the activating stimulus sensory receptors can be classified into electromagnetic receptors (photoreceptor, thermoreceptor), mechanoreceptors (hearing, touch, balance, osmoreceptor), and chemoreceptors (odorant receptor, gustatory receptor).

Detailed explanation-5: -Each sense receptor responds to different inputs (electromagnetic, mechanical, chemical), transmitting them as signals that travel along nerve cells to the brain. The signals are then processed in the brain, resulting in immediate behaviors or memories.
