What is the correct order of the basic Information Processing Model?

• Decision Making - Input - Output - Feedback

• Input - Feedback Output - Decision Making

• Input - Decision Making - Output - Feedback

• Input - Decision Making - Feedback - Output

Whose model did we look at for Learning Outcome 5.2.2

• Walford's

• Wilford's

• Wolford's

• Welford's

How many types of receptors are there?

• 2

• 3

• 4

• 5

The three types of receptors are...

• Interoceptors, Exteroceptors, Proprioceptors

• Interoceptors, Photoreceptors, Proprioceptors

• Photoreceptors, Exteroceptors, Proprioceptors

• Interoceptors, Exteroceptors, Photoreceptors

Sensory receptors that detect stimuli originating from the outside of the body.

• Interoceptors

• Exteroceptors

• Proprioceptors

Sensory receptors that detect stimuli coming from inside the body such as our internal organs, blood, blood vessels and intestines.

• Interoceptors

• Exteroceptors

• Proprioceptors

• Sensory receptors located in our subcutaneous tissues (beneath the skin) such as our muscles, tendons, joints and inner ear.

• Interoceptors

• Exteroceptors

• Proprioceptors

• Present near the surface of our skin and detect sound, smell, vision and sensations such as touch, pain, vibration and temperature. In other words, the traditional five senses!

• Interoceptors

• Exteroceptors

• Proprioceptors

• Main function is to send information to the CNS about the internal state of the body. 

• E.G. Heart Rate, Blood Pressure, Heart Rate, Blood Glucose, Oxygen Levels etc.

• Interoceptors

• Exteroceptors

• Proprioceptors

• Detect stimuli such as movement, muscle length, muscular tension and joint angle. The Golgi Tendon Organ is one example.

• Interoceptors

• Exteroceptors

• Proprioceptors
