_____ : Often involves picking out a suspect from 4 or 5 others in person or in a set of photographs
police lineups
84
- but in a 5 person lineup, people would pick the person the police suspected 20% of the time even if they picked randomly.
- in a 9 person lineup, theoretical odds of identifying the suspect are 11%
Police Lineups
85
the witness will almost always try to identify someone, even if the person is not in the lineup. This is known as
relative judgement theory
86
- we should be comparing the people in the lineup to our memory one at a time, but data indicates most folks compare the photos to each other, finding who looks most similar. (putting them together is comparing them to each other)
- it's essential to include some lineups with all innocent parties, so we know the false identification rate in that situation as well.

relative judgement
90
Rate of ___ ___ when suspect not present drops from 43% to 17%

..
94
Studies of these _____________ have found that the resulting pictures were no better at matching the subject than a hand drawing with pencil by the witness!
mechanized face construction systems
95
- Computer -- based systems such as E-Fit and Mac-a-Mug Pro

- Use of these required features to be identified in isolation from the face
- Yet humans have trouble recognizing features separately from faces -- known as the _________
The Second Generation
“face superiority effect”
96

Passport ID Judgements
101
___ are more accurate when given a composite picture of the person made from multiple other pictures

```
The Auditory System
In order to receive the sounds you have to go through three phases
1.
2.
3.
```
1. Reception- bringing the sounds into the inner ear
2. Transduction-- Transmuting the sounds into neural signals
3. Perception- Analyzing the sound waves.
113
The Ear
____- outside structure of the ear. Holds glasses up. It's shape has a purpose, catches sounds that may go past your ear and reflects them into the hole of your ear. Catches sounds and funnels them. Makes sounds louder than they would actually be. Animals that have external ear structures have better hearing.
Pinna
114
_______ : seems to have nothing in it, but it is a vignal part of your ear. You need this buffer because when it gets really cold, the buffer helps keep the cold out so your inner ear will not freeze.
Ear Canal

_____- vibrates to the sounds waves. The vibrations of those eardrums are transmitted to your inner ear to the Cochlea.
Eardrum
116
_____ : has 3 little bones. First bone is called hammer. Second one is andvol or incas. Third little bone is sturup.
Ossicles-
117

The ___, stiff and resonates to high pitches.
thin
| thick
121
Both eyes & ears have to deal with _____ _____-- the same object or sounds appears different from different angles. (you have to recognize the same sound when it is produced differently, by different voices. To recognize language, we have to be able to recognize the words such as “dog” whether person 1 says it or person 2 says it. How do we perceive it's the same word even when it's another person saying it.)
perceptual constancy
122
Both eyes & ears have _____ (trying to pick up the sound you are looking for even if they are other noise in the background) , figure/ground (try to recognize someone even if there are other people in the background) problems that must be dealt with

harmonics
125
When presented with ____ of a basic frequency, people often report they hear the basic frequency even when it's not there.
harmonics
126
_____ Suggests we need to consider the whole auditory stimulus and we can't engage in reductionism.
harmonics
127
People presented either two beeps with a short pause in between or two beeps with a buzz in between. (ex: standing behind a chair. You see the upper half and lower half but the chair is blocking the middle part. We still perceive him as one person, not two or cut in half. We know his body continues behind the chair). This is known as _______________
The Good Continuation Principle
128
_____________ : Argued there are certain invariant properties of a stimulus that perceptual systems can take advantage of
For example, the phoneme “b” has almost instant voicing, whereas “p” doesn't, regardless of the frequency of the person’s voice. (ex: someone that has learned English as a second language. They learned to ignore what might be critical to you in the English language. “New York Gankees”
Gibson’s Ecological View
129
The normal acoustic environment usually has multiple sounds overlapping. Breaking out individual parts is called _________
“auditory scene analysis”
130
Bregman argues that we use heuristics to break down the scene using _______, some of which are innate, someone of which are learned.
For example, if a stimulus consisting of a voice in one frequency range is heard a short distance apart with a different sound between, we assume the original voice carried through.
Gestalt principle
131
- Ciocca & Bregman presented a single tone or glides going either up or down, ending at the same point followed by a burst of noise, then one of a 9 following glides or tones.
- Only plausible tones or glides were heard as continuing through
- Called the ________ because the missing part is restored from the beginning & end part
“restoration effect”
132
- If the frequency of “A” was near “B”, they were heard as a single stream, with C as a separate tone, but if B was farther away A & B weren't linked
- If B & C were synchronous, people heard BC grouped and alternating with A
- Thus, there are two competing principle here- ________ & ________
proximity in frequency & temporal contiguity
133
_________ : if a sound is coming straight in front of you, the sound is equally as loud to both ears. If the sound is coming more from the right side, it's going to sound louder on right ear.
The sound is loud on the side of origination- doesn't work well for sounds in the vertical plane. (your ears are separated horizontally. If you hear something vertically, this model is useless.
Amplitude differences
134
___________ : the sound arrives at the close ear slightly ahead of the far ear- doesn't work well for sounds in the vertical plane or frequencies above 2000 Hz. (if you hear a sound time differences is not useful for where (behind or in front) )
Time differences
135
____________ : which frequencies are you hearing? The spectrum balance of sounds changes depending on where it is in the vertical. Works best when sounds covers a wide range of frequencies. (major que for vertical position of things)
Spectral information
136
We can locate sounds to within about _ degrees, and we may narrow that to _ degrees when the sound source is moving and contains a broad spectrum of sound.
_____ has argued that humans evolved in conditions where the ground was usually the only sound reflector and left- right position more important than up, down
5 : 2
Guski
137

souls
138
The same ____ sounds different depending on what sounds precede and follow it. (the ____ are not done the same way but sound alike)
phoneme
139
Phoneme sounds often start with the preceding sound and linger into the following one-- this is known as _____ (we do speech recognition easily but it is a complex process)
“coarticulation”
140
____ is more an orientating system than vision, so ____ doesn't need to be focused to pick up warnings of danger, and surprising sights don't cause alarm like surprising sounds. ( you automatically swing your head if you hear a sound, much more than the visual system. You don't have to be paying attention for the auditory system to alert you, but you have to be paying attention for the visual system to pay attention. You can be asleep and the auditory system will alert you)
Hearing
141
General office noise is disrupting to other ____ ___ , even if it's speech with no meaningful content (ex: people talking in a different language in the background) (ex: you hear the water heater in the background and you go out for a smoke. When you come back into the location, you have to relearn how to adapt to that background again)
cognitive tasks
142
We can _____ to the background noise, but a 5 min break restores the disruption
habituate
143
People usually can't report what went into one ear if they're ignoring it and giving attention to the other one. But they can tell if the voice was male or female, was speech or nonspeech, & they’ll notice if their ____ is spoken. (if at anytime someone speaks your ear to the ear you are not monitoring, your attention automatically turns into one ear. When you are listening into one ear but not listening on the other one, you still process ear to some degree. We can never totally tune out noise, we are always monitoring. Ex: if someone calls out your name)
name
144
If were shadowing one ear and the story switched to the other ear, we’ll follow it seamlessly and may not even notice we switched ears. (people do not notice if they switched ears. If you switch the story from one ear to the other ear, they will follow the story on the other ear. They just automatically do it. this proves that ___________________
YOU ARE ALWAYS MONITORING THE BACKGROUND !!!
145
__ and ____ movements contribute to accuracy of speech perception
When show video of people saying “ga” but shown saying “ba”, they go with what they see over 90% of the time. (People that are not able to do speak recognition. You can help them by speaking normally so they can see your face.)
Lip & Face
146
____ can be used in computer design to provided positive or negative feedback, especially if the event isn't visible, such as when it makes a text correction during editing.
Sounds
147
____ may be difficult to design-- they are sometimes reported as irritating or misleading. (you want a irritating sound when it's something critical/bad. You want something non irritating when it is something good)
Earcons
148
_______ : may be a benefit to cell phones, where visual information is limited. (ex: cell phone noise when it turning off. Visual info is limited because there is a noise made out of a car but you don't know what that noise is because every car has different noises)
Earcons
149
____ : Involves presenting some parameter of data in sound form.

150
ex of _____ : using an engine speed noise to indicate data-scrolling speed.
sonification
151
Users can distinguish objects, closed or open doors through _____
sonification
152
Design of _____ ____ `is critical: Firefighters wear personnel alerts that emit tones around 3000Hz. But high pitched signal tones are tougher to locate in space. (firefighters hear high pitches sounds, but then it's too loud that they do not know where it is coming from. We do not localize high pitches that easy)
warning sounds
153
____ ___ also are hard to locate left to right and front to the back- mixing in bursts of broad frequency noise significantly increases…..
Ambulance sirens
154
Machinery Alarms
It's important ____ be distinct from one another (they need to have different ___ for different systems. You do not know what is going wrong if the same alarm goes on for every single problem. Minutes count in the situation which is why you are supposed to know what is wrong then and there)
alarms
155
Most _____ ____systems consists of:
- An automatic system to translate sounds to text
- A language understanding unit to improve recognition
