1

Oculomotor Cues

Feedback from muscles around and within the eye. Cues from eye movement.

New cards
2

Accommodation

Relaxing (thinner lens, weaker focus, distant objects) and contracting (thicker lens, stronger focus, closer objects) the ciliary muscles changes the shape of the lens. Relays information for objects within about 2 meters.

New cards
3

Convergence

Eyes turn inward to keep objects in focus.

New cards
4

Binocular Disparity

Difference in the relative positions of objects in the retinal images of the two eyes

New cards
5

Optic Flow

How scene elements change as the observer moves THROUGH a scene. Motion Blur. Things closer to you move faster than things further away

New cards
6

Focus of Expansion (FOE)

Point the observer is moving toward. Objects closer to the FOE move outward slowly, objects closer to the observer move outward quickly. Rate deepens on distance from the observer, which can be used to infer depth

New cards
7

Deletion and Accretion

Objects are occluded (deleted) or revealed from behind occlusion (accreted). Specific distance where eyes do not cross

New cards
8

Disparity

Difference in retinal image

New cards
9

Crossed Disparity

In Front of Horopter

New cards
10

Uncrossed Disparity

Behind the Horopter

New cards
11

Motion Aftereffect

Cells get tired, perceive things spinning in one direction as spinning in the opposite.

New cards
12

Image Aftereffect

See opposite color when staring at a color for too long. ~ Smooth Pursuit: Continuous smooth movement of the eyes to track a moving object (or to track a stationary object while moving)

New cards
13

Bimodal Neurons

Respond to TWO modalities (kinds of senses such as visual and tactile)

New cards
14

Cocktail Party Problem

Attend to and understand a single convo in a sea of noise. Other conversations are unattended

New cards
15

Broadbent’s Filter Theory of Attention

“People do not process unattended stimuli beyond basic physical properties.” *States that Information is unavailable for later recall.

New cards
16

Divided Attention

Attending multiple things at a time.

New cards
17

Feature Search / Pop-Out Effect

Single differences pop out. “Features” of things being searched for.

New cards
18

Top-Down Control

Voluntary attention, reflects deliberate conscious goals. ~ “Goal-relevant stimuli.”

New cards
19

Bottom-Up Control

When low-level stimuli “capture” attention independent from the observer’s goals or intentions

New cards
20

Frequency

More waves, pitch, notes of a song. Number of wave cycles per second

New cards
21

Loudness

Perception of how loud something is, amplitude. Physical pressure of sound.

New cards
22

Timbre

Sound quality - Tuning Fork vs Singing Drunk Dudes

New cards
23

Cochlea

In the inner ear

New cards
24

Auditory Path

Type 1 Auditory Nerve Fibers in Cochlea send info to the ipsilateral cochlear nucleus. Info first sent to the nucleus on the same side before crossing.

New cards
25

Pinna

Weird ear wiggle shape. Useful in perceiving elevation

New cards
26

Where and What streams

Similar to visual, connect to visual

New cards
27

What stream

identifying and goes ventral temporal to frontal

New cards
28

Where stream

location and goes dorsal temporal to parietal

New cards
29

Perceiving elevation / distance of sound

Related to sound entering the pinna

New cards
30

Spectral Shape Cue

Pinna-induced modification in a sound’s frequency spectrum. Modification of sound depends on elevation, allowing differences in frequency spectrum to be used to estimate elevation.

New cards
31

Interaural Level Differences (ILD)

Relative loudness at two ears

New cards
32

Acoustic Shadow

Head partially blocks sound waves traveling through it. Higher impact on higher frequencies

New cards
33

Interaural Time Differences (ITD)

Relative time of arrival at the two ears. ~ Sound takes slightly longer to reach one ear than the other when sound is off center. Time difference is less than a millisecond, but still detected. Most effective for sudden onset sounds (clap, bang, snap) as opposed to complex extended waveforms

New cards
34

Doppler Effect

Soundwaves compress with movement

New cards
35

Phonemes

Smallest units of sound that, if changed, can change the meaning of a word. Ex: bAd Vs. bEd

New cards
36

Vowels

Speech sounds produced with a relatively unrestricted flow of air through the pharynx and oral cavity. Produced by varying size and shape of the oral cavity.

New cards
37

Broca’s Aphasia

Frontal lobe damage, impaired production but intact comprehension

New cards
38

Wernicke’s Aphasia

Near the temporal junction, impaired comprehension but intact production.

New cards
39

Deletion

Objects are occluded

New cards
40

Accretion

revealed from behind occlusion
