Psychology Unit 5/6 Review (quiz)

Scientific name for sight

Vision

Scientific name for hearing

Audition

Scientific name for smelling

Olfaction

Scientific name for tasting

Gustation

Are we learning a name for touch?

No

Talks about three colors—red, green, and blue. Red has the longest wavelength and blue has the shortest. We see colors in the visible spectrum as a result of the combination of these primary colors.

Trichromatic theory

How many cones in our eyes

6 million

How many rods

120 million

How do we know the trichromatic theory is true

The existence of color blindness

Are some of the cones broken?

Yes

We have so pair of color sensitive neurons—red/green pair, and blue/yellow pair. As colors like green and yellow are stimulated. Red and blue are inhibited.

The opponent process theory

A blank proves the opponent process theory true

Afterimage

Which eye cell responds to light quickly?

Cones

Rods and cones are known as?

Photoreceptors

What does this mean, “our experience of sensation is relative to the duration of exposure.”

◦ This is talking about sensory adaptation. We cannot feel stimuli that occur very commonly.

Sensory adaptation is quickest in:

The nose

The first time you hear a beep or the first letter you see on a vision screening.

Absolute threshold

The difference between one stimuli and a constant addition of that stimuli until you notice it. (Paper example, hot sauce example)

Just noticeable difference or JND

a example of a difference threshold.

JND

Everything that reaches the brain must go through this process:

Transduction

‣ The process of making meaningless sensations and making them perceptions. They are turned into electrical signals (coded neural signal) and they are processed in the brain. Then we can tell what something is.

Transduction

◦ says that the change in stimulus should be proportional or relative to the initial stimulus.

Weber’s Law

when an object is coming in a little bit lower than our sensory threshold. Is a common marketing technique

Subliminal messaging (subliminal perception)

What part of our eye lacks rods and cones all together?

Optic disc

the sense is activated by dissolvable chemicals in our saliva.

Taste

the sense is activated by vibrations or sound waves.

Hearing

the sense is activated by light waves.

Sight

the sense is activated by air borne odor molecules.

Smelling

the sense is activated by pain, pressure, and temperature.

Touch

Wavelengths of light that we can see make up the

Visible spectrum

Because of the blank sense, you know where your body is without sight

Kinesthetic sense
