Flashcards in Sensory Processing Deck (28):
0

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

Absolute Threshold

1

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

Differential Threshold

2

This is the MAXIMUM energy sensed.

Terminal Threshold

3

This is the RELATIONSHIP between PHYSICAL ENERGY and EXPERIENCE.

Psychophysics

4

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

Constant Stimulus

5

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

Method of adjustment

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

Method of Limits

7

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

Sensation

8

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

Perception

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.

Webber's Law

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

10

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

Transduction

11

Where does TRANSDUCTION occur?

Sensory Synapse

12

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

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

13

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

Adequate Stimulus

14

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

Inadequate Stimulus

15

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

Light

16

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

Pressure, electric shock, mechanical irritation.

17

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

Coding

18

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

Unspecialized Neurons

19

These SENSORY RECEPTORS subserve in VISION and OLFACTION.

Specialized Neurons

20

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

Specialized Epithelial Cell-Neuron Combinations

21

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

Adaption

22

True or False: ADAPTION is caused by RECEPTOR FATIGUE.

TRUE

23

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

Habituation

24

Habituation is sometimes referred to as _______________.

Sensory Gating

25

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

After Images

26

These AFTER IMAGES result from BRIEF, INTENSE STIMULATION.

Positive After Images

27

These AFTER IMAGES result from PROLONGED stimulation.

Negative After Images
