Question 1

The process by which we receive information from the environment and encode it as neural signals:

Answer 1

Sensation

Question 2

The process of selecting and interpreting information from the environment (How individuals put things together):

Answer 2

Perception

Question 3

The study of the relationship between physical energy and psychological experience:

Answer 3

Question 4

The first area of psych to be studied as a science:

Answer 4

Psychophysics

Question 5

The sensory analysis that starts at the entry level and works up to a higher level:

Answer 5

Bottom-up Processing

Question 6

Constructing perceptions drawing both on sensations coming bottom-up and on our experiences and expectations (applying what we know):

Answer 6

Top-down Processing

Question 7

The first person to study the relationship between stimulus intensity and sensation intensity

Answer 7

Gustav Fechner

Question 8

Who created the absolute threshold?

Answer 8

Fechner

Question 9

1. The point at which a stimulus can be detected 50% of the time
2. The minimum amount of stimulation needed to detect a stimulus

Answer 9

Absolute Threshold

Question 10

There is no absolute threshold because the threshold changes with a variety of factors:

Answer 10

Signal Detection Theory

Question 11

The receipt of messages that are below one’s absolute threshold (no trigger):

Answer 11

Subliminal Stimulation

Question 12

A change between two stimuli that can be detected 50% of the time:

Answer 12

Difference Threshold

Question 13

Who discovered Weber’s Law?

Answer 13

Ernest Weber

Question 14

Two stimuli must differ by a constant minimum percentage to be perceived as different:

Answer 14

Weber’s Law

Question 15

What forms do environmental info exists as?

Answer 15

Air vibrations, gases, and chemicals

Question 16

What the body receives the forms through:

Answer 16

Special Receptor Cells

Question 17

Converting one form of energy into another:

Answer 17

Transduction

Question 18

What is receptor sensitivity sensitive to?

Answer 18

Change

Question 19

A weakened sensitivity due to prolonged stimulation:

Answer 19

Sensory Adaptation

Question 20

A decline of the sensory sensitivity at the neural level due to repeated stimulation:

Answer 20

Habituation

Question 21

How is habituation different from sensory adaptation?

Answer 21

Responsiveness can reappear if the stimulation is increased or decreased (Habituation)

Question 22

What you choose to attend to out of all the stimulation reaching you:

Answer 22

Selective Attention

Question 23

You can pay attention to multiple sensory inputs:

Answer 23

Divided Attention

Question 24

You hear/see two different things and are told to pay attention to both:

Answer 24

Dichotic Listening/Viewing

Question 25

People are asked to name the colors of the words and not read the words:

Answer 25

Stroop Effect

Question 26

The interference occurs because words are read faster than colors are named:

Answer 26

Speed or Processing Theory
