Document Summary

Criteria used to determine if stimulate is present is criteria fluctuate, apparent sensitivity fluctuates, criteria changes depending on other factors, fatigue, importance of stimulus: and expectation. In order for difference threshold it to make a difference in carrying weight, it must be 1/50 for example if something weights 500 lbs it order to feel more weight being added it must be 10 lbs. The eye: thinner to focus on distant objects and thicker to focus on nearby objects. Dark adaptation: rods are not sensitive to wavelengths of red light, they remain dark adapted and therefore, can go from red light to dim/dark conditions. Photoreceptors: bipolar cells synapse with ganglion cells, axons of ganglion cells form optic nerve, create blind spot where optic never exits from eye. The images we see are not made of light; they are made of neural signals which can be produced even by pressure on the eyeball.
