Sensarions

Question 1

Place theory

Answer 1

Our perception of sound depends on where each component of frequency produces vibrations along with the basilar membrane

Question 2

Frequency theory

Answer 2

Dates that the rate of nerve impulses traveling up the auditory nerve matches the frequency of tone, thus enabling us to sense It’s pitch

Question 3

Bottom up processing

Answer 3

Analasys of the stimulus begins with the sense receptors and works up to the level of the brain and mind

Question 4

Top-down processing

Answer 4

For Maisch and processing guided by higher level mental processes as we construct perceptions drawing on our experience and expectations

Question 5

Absolute threshold

Answer 5

Absolute threshold is the smallest level of energy required by an extern all stimulus to be detectable by the human senses 50% of the time

Question 6

Subliminal stimulus

Answer 6

Below one’s absolute threshold for conscious awareness

Question 7

Signal detection theory

Answer 7

Predicts how and when we detect the presence of a faint stimulus signal) amid background noise (other stimulation). Signal detection theory assumes that there is no single absolute threshold and detection depends upon person’s experience expectations motivation and tiredness

Question 8

Signal detection theory says that detection depends on what

Answer 8

Persons experience expectations motivation and level of fatigue

Question 9

Stroop test

Answer 9

The strip affect is a demonstration of interference in the reaction time of the task,

Question 10

Webbers law

Answer 10

To stimuli must differ by a constant minimum percentage rather than a constant amounts to be perceived as different

Question 11

Please the parts in order in which light enters the eye

Answer 11

Cornea
Iris
Pupil
Lens
Retina
Fovea
Optic nerve to brains visual cortex

Question 12

Accommodation

Answer 12

The process by which the eyes lens changes shape to help focus near or far objects on the retina

Question 13

Retina

Answer 13

The light-sensitive inner surface of the eye, containing receptor rods and cones in addition to layers of other neurons that process visual information

Question 14

Optic nerve

Answer 14

Carries neural impulses from the eye to the brain

Question 15

Blind spot

Answer 15

Point where the optic nerve leaves the eye because there are no receptor cells are located there

Question 16

Fovea

Answer 16

Central point in the retina around which the eyes cones cluster

Question 17

Visual information processing

Answer 17

Optic nerve connect to the Salamis in the middle of the brain and I found this connects to the visual cortex

Question 18

Bipolar and ganglion cells

Answer 18

Bipolar cells receive messages from photo receptors and transmit them to gangly on cells which are for the optic nerve

Question 19

Trichromatic three Color theory

Answer 19

Young-helmholtz
Retina contains three different color receptors

One each sensitive to red green blue

And stimulated they produce the perception of any color

Does not explain after images

Question 20

Opponent process theory

Answer 20

States that sensory receptors in the retina come in pairs
Red/green
Yellow/blue
Black/white
If one sensor is stimulated it’s pair is inhibited from firing

Question 21

Achromatopsia

Answer 21

Total color blindness

Question 22

Conduction hearing loss

Answer 22

Hearing loss caused by damage to the mechanical system that conducts soundwaves to the cochlea

Question 23

Sensorineural hearing loss

Answer 23

Hearing loss caused by damage to the cochlea’s receptor cells or to the auditory nerve, also called nerve deafness

Question 24

Frequency theory best explains how we perceive what

Answer 24

Pitched sounds

Question 25

The sense of touch is a mix of four distinct skin senses which are

Answer 25

Pressure warmth cold and pain

Question 26

Gate control theory

Answer 26

Mel Zack and wall proposed that are spinal cord contains a neurological gate that either block pain or allow it to be sensed

Question 27

Smell and memories

Answer 27

Region for smell is closely connected with the brain region involved with memory the limbic system. That is my memories are made through the sense of smell

Question 28

Sensory interaction

Answer 28

When one cents affects another sense. So the taste of strawberry interacts with its smell and it’s texture of the tongue to produce flavor

Question 29

Kinesthesis

Answer 29

Is the sense that gives us information about the location of our body parts with respect to each other and allow us to before movements. Information comes from the receptors in joints ligaments and muscle fibers

Question 30

Vestibular senses

Answer 30

Give this information about body position and movement and acceleration factors critical for maintaining our sense of balance. The sensory organs for the vestibule or sensor located in the linear ear vestibular socks and semicircle canals which both contain fluid that moves in the head rotates
