Sensation & Perception

Question 0

International Blindness

Answer 0

is the event in which an individual fails to recognize an unexpected stimulus that is in plain sight

Question 1

Change Blindness

Answer 1

a phenomenon in visual perception where apparently large changes within a visual scene are undetected by the viewer

Question 2

Transduction

Answer 2

The process of converting one form of energy into another; translation of incoming stimuli into neural signals

Question 3

Psychophysics

Answer 3

This area of psychology was started by Gustav Fechner; addresses the relationship between psychological experiences and physical energy

Question 4

Signal Detection Theory

Answer 4

Investigates the effects of the distractions and interference we experience while perceiving the world

Question 5

Difference Threshold

Answer 5

Sometimes called the just-noticeable difference threshold, is the smallest amount of change needed in a stimulus before one can detect a change

Question 6

Sensory Adaptation

Answer 6

Decreasing responsiveness to stimuli due to constant stimulation

Question 7

Extrasensory Perception

Answer 7

ESP, also called sixth sense, includes reception of information not gained through the recognized physical senses but sensed with the mind.

Question 8

Parapsychology

Answer 8

refers to the study of paranormal phenomenon; believe that people who experience paranormal phenomenon are not always mentally ill or delusional

Question 9

Blind Spot

Answer 9

The spot where the optic nerve leaves the retina has no rods or cones

Question 10

Parallel Processing

Answer 10

the ability of the brain to do many things (processes) at once.

Question 11

Opponent Process Theory

Answer 11

States that the sensory receptors arranged in the retina come in pairs: red/green, yellow/blue, black/white

Question 12

Visual Cliff

Answer 12

Experiment by Eleanor Gibson that was used to determine when human infants can perceive depth

Question 13

Binocular Cues

Answer 13

Depth cues that depend on having two eyes

Question 14

Retinal Disparity

Answer 14

The way that your left eye and your right eye view slightly different images when the other eye is closed

Question 15

Monocular Cues

Answer 15

Depth cues that do not depend on having two eyes

Question 16

Perceptual Adaptation

Answer 16

Our perception of sensations is partially due to how we focused we are on them

Question 17

Frequency

Answer 17

Length of waves that determine pitch

Question 18

Pitch

Answer 18

refers to the sound quality; highness or lowness (frequency) of a sound or musical tone; sounds or pitch refers to a sound’s place on the frequency scale

Question 19

Sensorineural Hearing Loss

Answer 19

Occurs when the hair cells in the cochlea are damaged, usually by loud noise

Question 20

Conduction Hearing Loss

Answer 20

Occurs when something goes wrong with the system of conducting the sound to the cochlea (in the eardrum, ear canal, hammer/anvil/stirrup, or oval window)

Question 21

Place Theory

Answer 21

Holds that the hair cells i the co chela respond to different frequencies of sound based on where they are located in the cochlea

Question 22

Frequency Theory

Answer 22

theory of how we hear sounds; states that there are pulses that travel up the auditory nerve, carrying the information about sound to the brain for processing, and that the rate of this pulse matched the frequency of whatever tone you are hearing exactly.

Question 23

Gate-Control Theory

Answer 23

Explains how we experience pain the way we do; explains that some messages have higher priority than others

Question 24

Vestibular Sense

Answer 24

Tells us how our body is oriented in space; located in the ear

Gustav Fechner

Answer 25

The creator of psychophysics
