Sensory Processing

Question 0

This is the least amount of physical energy that can be perceived as being DIFFERENT from a standard. (50% of time)

Answer 0

Differential Threshold

Question 1

This is the least amount of physical energy that can be perceived (50% of time).

Answer 1

Absolute Threshold

Question 2

This is the MAXIMUM energy sensed.

Answer 2

Terminal Threshold

Question 3

This is the RELATIONSHIP between PHYSICAL ENERGY and EXPERIENCE.

Answer 3

Psychophysics

Question 4

This is when the experimenter presents RANDOMLY VARYING intensities of stimulus.

Answer 4

Constant Stimulus

Question 5

This is when the SUBJECT varies the intensity of a stimulus.

Answer 5

Method of adjustment

Question 6

The experimenter starts well above the threshold then gradually decreases intensity in a series of steps, the starts well below threshold and gradually increases in steps

Answer 6

Method of Limits

Question 7

This is the immediate impression that senses make on the brain, process of detecting presence of stimuli.

Answer 7

Sensation

Question 8

This is the higher order process of integrating, recognizing and interpreting complex patterns of sensation.

Answer 8

Perception

Question 9

This is utilized with the differential threshold and states that if ORIGINAL intensity is LOW, not much must be added to detect a difference but if it is HIGH, then a GREAT DEAL must be added.

Answer 9

Webber’s Law

Holds for original and med but breaks down at hight original intensity.

Question 10

This process is the CONVERSION of PHYSICAL ENERGY into NERVE IMPULSES.

Answer 10

Transduction

Question 11

Where does TRANSDUCTION occur?

Answer 11

Sensory Synapse

Question 12

True or False: JOHANNES MÜLLER noted that GROSS SENSORY QUALITY depends on how it is stimulated.

Answer 12

FALSE, gross sensory quality DEPENDS ON WHICH NERVE IS STIMULATED.

Question 13

This type of STIMULUS is the one to which the receptor RECEPTOR SYSTEM is most SENSITIVE and requires the LEAST amount of energy.

Answer 13

Adequate Stimulus

Question 14

This type of STIMULUS is one to which the ORGANISM will RESPOND but REQUIRES a GREAT AMOUNT of ENERGY.

Answer 14

Inadequate Stimulus

Question 15

Give an example of an ADEQUATE STIMULUS for the eye and vision.

Answer 15

Light

Question 16

Give an example of an INADEQUATE STIMULUS for the eye and vision.

Answer 16

Pressure, electric shock, mechanical irritation.

Question 17

This is a process in which SENSORY RECEPTORS generate SPECIFIC PATTERN.

Answer 17

Coding

Question 18

These SENSORY RECEPTORS are FREE NERVE ENDINGS that subserve PAIN, WARMTH, COLD, DIFFUSE LIGHT TOUCH.

Answer 18

Unspecialized Neurons

Question 19

These SENSORY RECEPTORS subserve in VISION and OLFACTION.

Answer 19

Specialized Neurons

Question 20

These SENSORY NEURONS subserve AUDITION, BALANCE, TASTE, SPECIFIC LIGHT TOUCH, PRESSURE and KINESTHESIS.

Answer 20

Specialized Epithelial Cell-Neuron Combinations

Question 21

This is a DECREASE IN RESPONSE of RECEPTOR and DECREASE IN PERCEIVED INTENSITY of a stimulus resulting from a CONSTANT RATE of STIMULATION.

Answer 21

Adaption

Question 22

True or False: ADAPTION is caused by RECEPTOR FATIGUE.

Answer 22

TRUE

Question 23

This is a LOSS OF ATTENTION to a stimulus caused by repetition or LACK OF NOVELTY.

Answer 23

Habituation

Question 24

Habituation is sometimes referred to as _______________.

Answer 24

Sensory Gating

Question 25

This occurs when RECEPTORS CONTINUE TO RESPOND after a stimulus stops acting upon them.

Answer 25

After Images

Question 26

These AFTER IMAGES result from BRIEF, INTENSE STIMULATION.

Answer 26

Positive After Images

Question 27

These AFTER IMAGES result from PROLONGED stimulation.

Answer 27

Negative After Images
