The Senses
THE SENSES • The senses are the human brain’s connection to the outside world. Sight Smell Taste Hearing Touch
WHAT IS SENSATION? we detect physical energy (stimulus) from the environment through our sensory organs (eg. Eye) sense organs have sensory receptors (transducers) designed to receive specific types of stimuli. the physical energy is then converted into neural signals – this is called transduction
SENSORY RECEPTORS After the stimulus is interpreted by the appropriate sensory receptor (eg. You touch a hot stove), the message travels to “sense-specific” areas of the brain the message travels along sensory neurons our brain receives and interprets the neural signals, causing sensation. (OW! That stove was hot!)
Sensation: - Is bottom-up processing-analysis that starts with the senses - In other words, your brain takes in information to help it understand the world
Sensation
• Sensation is initiated in the senses through sensory reception, but sensation and perception take place in the brain.
PERCEPTION: WHEN WE SELECT, ORGANIZE, AND INTERPRET OUR SENSATIONS, THE PROCESS IS CALLED PERCEPTION. § Our sensory and perceptual processes work together to help us sort out complex processes
Observation Sense Rate: # 8 -9 observation senses is average. # 10 -11 observation senses is above average. # 13 observation senses is extraordinary. # 14 -17 observation senses is extremely extraordinary.
Perception: Top-Down Processing-analysis based on experience and expectation (starts with the brain) Perception enables us to literally navigate through the world, avoiding danger, making decisions, and preparing for action. Our perception becomes very different if our senses are “thrown off” – eg. Sun is in our eyes, have a bad cold, break a bone
THE SENSE OF TOUCH Your body is covered with skin tissue, which means that your sense of touch is usually a result of your skin contacting a surface. There are 5 types of stimuli that can be perceived by the skin Tactile – usually simply called “touch. ” Receptors to both touch and pressure are called Mechanoreceptors. Pressure – a “heavy touch. ” Temperature – hot or cold. Receptors to temperature are called Thermoreceptors. Pain – When something is damaging your tissues. Receptors to pain are called Nociceptors. Vibration – an “on-and-off” type of touch.
