12
Q
What is Stimulus Salience?
A
Refers to idea that some stimuli in the environment capture attention because of their physical properties
13
Q
Define Attentional Capture
A
Having more knowledge in a certain area makes us allocate our attention to the more important features of the scene and ignore the less relevant info
14
Q
Explain the Dichotic Listening Task
A
One stream of info is going to one ear, while a different message is played in the other ear. The participant is to attend to only one message.

3 Main Features of Interest in stages of sleep (FAR)
Freq. of waves (HZ) - up + down cycles of wave/sec
Amp. - differ between stages of sleep
Regularity of wave - difference in pattern of activity. Consistency
29
What are two patterns that are observed when you are awake? (BA)
Beta Waves - Person is alert and active. waves on EEG when a person is alert and actively processing info. Freq. 13-30 Hz
Alpha Activity - awake but relaxed. 8-12 Hz. Alpha waves go into theta waves (falling asleep)
30
What does desynchrony in Beta Waves tell you?
Different neuronal circuits in the brain are actively processing info
31
What helps with the transition from Stage 1 into Stage 2? (SK)
Sleep Spindles - bursts of activity, 2-5x/min during Non-REM sleep. More spindles = higher IQ
K-Complexes - pattern of neural excitation followed by neural inhibition occurring during stage 2 sleep. Prepares the brain to enter delta wave activity
32
What is slow-wave sleep?
Sleep stages 3-4, delta waves (slow, regular, high amp. waves) (1.5-4 Hz)
33
What happens in REM stage of sleep?
Dreaming, EEG recordings become highly irregular
34

Bursts of activity 2-5x/min (sleep spindles)
Excitation followed by neural inhibition about once per min in preparation for deeper sleep (K-complexes)
41
Stage 3 -Slow-wave sleep
Occurs 15-20 min after stage 2
Transition to delta activity (slow (less than 4 Hz), regular, high-amp. waves)
One neural inhibition and period of excitation each wave
Will feel groggy if woken
42
Stage 4 - REM
Desynchronized theta waves appear - easier to wake up
Dreams, sleep paralysis
After completion with 1 cycle you go back to stage 1
More time is spent in REM than deep sleep as night progresses (4-5x/night)
43
Regions that have the highest activity during waking hours show what?
Reduction in metabolic activity and most delta activity during slow-wave sleep (suggesting this part of the brain is resting)
44

Occurs during SWS
62
What are Zeitgebers?
Cues from environment that set bio clocks
63
Circadian Rhythms
Tells body when to sleep and wake
64
Suprachiasmatic Nucleus (SCN)
structure in brain, next to optic chiasm, sets circadian clock for body
65
What happens in the SCN to set the circadian clock for the body?
sends signals to several regions of the brain, among them the pineal gland. In response to the light/dark cycle, the pineal gland secretes melatonin. Melatonin levels are highest right before bed and seem to signal to the brain that light is absent
66
Which of these is relevant to sleep deprivation: "springing forward" an hour, or "falling backward" an hour?
There is a noticeable increase in traffic accidents immediately following the spring shift.
67
What does alcohol do?

In the early 1900s
79
Define Pavlovian Conditioning
Seemingly insignificant event signals an important event.
80
What is the main role that a conditional stimulus plays?
Provides information about the presence or absence of an unconditional stimulus
81
What is a conditional response (or reflex)?
Learned response that occurs to the conditional stimulus in preparation for the US
82
Stimulus is anything in the environment we can (3):
Detect
Is measurable
Can evoke a response or behavior
83

Biologically important EVENT requires no conditioning to affect our behavior
84
What is an UR (Innate Reflex)?
Biologically important RESPONSE occurs because of US
85
In Pavlov's experiment what were the different factors? Name the CS, CR, US, UR
CS - Lab Coat (went from neutral to CS)

Long-Delayed - been there for a while
Trace Conditioning - min. or hours after CS has stopped
90
What category of conditioning do Simultaneous and Backward Conditioning fall into?
Inhibitory Conditioning - CS indicates that no US will occur
91
Simultaneous conditioning
CS and US occur at the same time, overlapping completely
92
Backwards Conditioning
US occurs before CS
93
Garcia and Koelling (1996) and what did they study?
Flavour conditioning with rats (taste aversion)
94
Explain Pavlovian Extinction
CS is presented without a US, so the CS loses its ability to signal an event. Ex. Wearing the lab coat for 7 days without the food
95
Explain Spontaneous Recovery
After extinction the signal may randomly appear alone, and CR response may reappear. Ex. After the extinction example if for 7 days after the lab coat was not worn at all it would only take one instance of wearing it again for the dogs to start salivating again.
96
Attainment by an individual of new behavior, info, or skills
Acquisition
97
Two categories that US can be
Appetitive - something you like and will work for Ex. baked cookies
Aversive (also called noxious) - something you don't like and will not work for Ex. Spoiled food

Effect in which an animal notices similarities between objects and responds to the objects as if they were the same. Ex. Fearing all spiders instead of just one type
Stimulus Generalization
99
Effect in which an animal notices differences between objects and responds to the objects as though they were different
Stimulus Discrimination
100
What is Higher-Order Conditioning
Conditioning procedure in which an already-conditioned signal is paired with a neutral stimulus or currently meaningless event.
101
John B. Watson's Perspective
Environment is important to behaviorism. Psychology could be measured by constructs like behavior, without considering subconscious thoughts or feelings.

Thorndike
105
What is meant by the term "Instrumental", when it comes to Operant conditioning?
Trying new response options that could effect the environment and/or your problem. Ex. Finding break box in dark house
106
What law did Thorndike develop?
The law of effect - how we learn about situations and behaviors leading to something we like
107
Satisfaction (stamping in)
Learning behaviors that lead to something we like; learn to repeat that behavior

SPECIFIC consequence given for picking certain item
VS.
NO difference in consequence even though different actions or items are being used
114
What is the "Dead Man Test", and who created it?
A term used to help determine whether something is behavior or not: If a dead man can do it, it is not behavior. Ogden Lindsley created it.
115
If-then rule, if you do this then this will happen is called what?
Contingency - occurs before a behavior
116
What is it called when a consequence INCREASES the probability of that behavior occurring again?

119
What is main purpose of contingency and the 4 procedures?
To determine if the consequence will be produced or removed in the future
120
Negative Reinforcement occurs in 2 forms, what are they?
Escape - responding in a way to stop something from happening. Ex. Turning off alarm clock to stop the sound
Avoidance - responding to prevent something you don't want from happening. Ex. Umbrella for rain so we don't get wet
121
What operant process did Skinner believe had the greatest influence on behavior?
Positive Reinforcement
122
Explain Operant Extinction
Behavior previously reinforced now produces no consequence and goes away; the response is not reinforced and decreases
123
3 Behavioral Effects of Extinction
Extinction burst - temp. increase in responding
Emotional and Aggressive responding
Responding eventually stops
124
What is Blindsight and how do these people who are affected by this walk around?
Legally blind.
Light can bounce off a stool and hit the retina of the eye so they can walk around it
125
What hormone does the Pineal gland produce?
Melatonin - sleep-inducing
126
What is Adenosine and what does it do?
When the body runs out of fuel this chemical inhibits neural activity and causes drowsiness
127

Decreases melatonin production
128
Production of melatonin cannot be triggered in what individuals?
Blind individuals
129
Two ways to 'reset our clock' if we have jet lag
1. Exposure to light (decrease melatonin production)
2. Take melatonin pill - helps us fall asleep to get back on schedule
130
Does caffeine act as an agonist or antagonist to adenosine and why?
Antagonist - it blocks the adenosine receptors so that it cannot be produced. Stops the drowsiness
131
Why do older people not sleep as much?
They no longer have the GH released from the pituitary gland
132

134
In regards to Habituation, what happens as time goes on?
Partial recovery
THEN
Full recovery
135
Are Pavlovian and Classical Conditioning the same?
Yes. They are an association between a neutral stimulus and a meaningful stimulus
136
What is a taste aversion?
Getting sick from a certain type of food and from then on associating the food with that bad experience
137
Define Compensatory Response (HINT: Drugs)
Taking away info that prepares for a drug like heroine. Your body knows you are going to take it because of a certain environment. But if you are in a different spot your heart rate may not up t compensate like it usually does (overdosing)
138
Difference between Classical and Operant Conditioning
Classical - forms association between 2 stimuli
Operant - forms association between a behavior and consequence
139

142
Variable Ratio VS. Variable Interval
Reinforces after an unpredictable number of correct responses Ex. Win at a slot machine
VS
Reinforces for first correct response after an unpredictable time period Ex. Updates on the news
143
What is Intermittent (partial) reinforcement?
Reinforced sometimes when behavior occurs
144
Which reinforcement schedule would work best for acquisition?
Continuous - in learning the skill they can associate a behavior with a response
145
Describe Humphrey's paradox
Another name for the partial reinforcement effect, or the seemingly paradoxical finding that a response that is only intermittently reinforced is more resistant to extinction than a response that is reinforced every time it occurs.
146
Describe latent learning
Not being consciously aware that you are or are learning a skill, or gaining new information just by observing. Ex. Child watching parents drive a car, they are then able to determine maybe where the pedals are located
147
What is the best reference image to compare your mind to?
The mind is like a computer.
Encoding (typing)
Storage (save)
Retrieval (search and open)
148

149
Who developed the early Modal Model of the Mind theory?
Atkinson and Shiffron 1968

In the early model of the mind where was the input said to be analyzed?
Analyzed at the STM. Also, that is where rehearsal, coding, and retrieval were said to be found
151
Problems with A&S Multi-Store Model
Probability of memories going into LTM increases with the time it is held in STM.
NOT TRUE
Memories held in STM don't always end up in LTM
152
What two people modified the Memory model?
Baddeley and Hitch (1974)
153
What did the modification of the memory model consist of?
STM was seen as WM because it does more than just hold the material, it works on it
154
What is the Updated Modal Memory Model?
Sensory input -> Sensory memory - > WM (maintenance rehearsal) -> Encoding from WM leads to LTM
GOES BACK TO WM WHEN INITIATING RETRIEVAL
155
What is Iconic Memory and who created the idea?

166
What is the search metaphor and who created that idea?
It describes processes involved in memory using terms and phrases that relate them to looking around in physical or virtual space. Ex. Mental purse(Roediger 1980)
167
Instead of the search metaphor what is a better metaphor for memory and why?
Reconstruction (Neisser 1967) - specifically search for info to create a useful response given the situation at hand and what you've stored
168
What does encoding problem and storage problem refer to?
Problem the brain must solve to transform an experience into memory and maintain the info over time (physical representation)
169
How long will sensory memory hold onto information?
Long enough for us to stitch one moment of our experience to the next.
170
Iconic memory VS Echoic memory
Fleeting afterimages VS lingering neuronal activity called an echo

Other names for Immediate memory
STM OR WM
172
Immediate memory and the three main properties
Representation, duration, and capacity
173
Baddeley and Hitch (1974) proposed the mechanism called the central executive, what is it?
Within WM, it's job is to direct flow of info to and from phonological loop and visuospatial sketchpad, but also to and from long-term memory
174
What are semantic memories?
Contents relate to specific facts and pieces of meaningful info not based on personal experience
175
Deep VS Shallow Processing
Encoding new info through meaningful connections to existing knowledge
VS
Encoding info based only on its surface characteristics
176
4 Types of Elaboration

179
Were inanimate or animate objects easier to remember for humans?
Animate - more salient. Brains have evolved to pay attention to it
180
Free recall VS Cued recall
Remembering previously learned info without any other context to aid in remembering
VS
Remembering previously learned info with aid of clue to provide context
181
What is the encoding specificity principle? (Tulving and Thompson 1973
Idea that retrieval cues are only useful as long as they match the original context of how-to-be-remembered info was originally learned
182
Transfer Appropriate Processing (Lockhart 2002)
Observation that engaging in similar processes at both encoding and retrieval tends to enhance recall on final test
183
Explicit VS Implicit Memory

184
Who created the errors of omission and commission?
Daniel Schacter (2002)
185
Errors of Omission VS Commission
Memory errors where info cannot be brought to mind
VS
Memory errors where wrong or unwanted info is brought to mind
186
Name the three errors of omission
Transience, absent-mindedness, and blocking
187
What is Transience?
We may be unable to retrieve info - forgotten due to interference of info being processed currently
188
Retroactive interference VS Proactive interference
Inability to retrieve older info due to influence of newer, similar info
VS
Inability to retrieve new info due to older, similar info
189
Absent-mindedness
Description of how memories sometimes are simply unavailable because of a failure to encode them
190
Blocking
In some cases, not enough distinctive cues are available to help us recover a specific memory
191
4 Errors or Commission
Misattribution - incorrectly recall the source of info (deja vu)
Suggestibility - requires info that is misremembered to have been suggested by an outside source
Bias -
Persistence -
192
Misinformation Effect
misleading info alters subsequent memory, typically an eyewitness account
193
Schema (part of sin of Bias)
Highly organized Knowledge structure that contains many pieces of specific info. May lead to over-generalization
194
Persistence
Description of how memories are sometimes retrieved when they are not wanted
195
What is Hyperthymesia?
Medical condition leading to near perfect autobiographical recall
196
Retrograde VS Anterograde Amnesia
Loss of memories prior to specific trauma event (maybe a blow to the head)
VS
Inability to encode new info into LTM (can't form new memories)
197
Why did Henry Molaison have his hippocampus removed?
To stop his severe epileptic seizures. Had both types of amnesia
198
Data regarding H. M. provided evidence for the distinction between:
Immediate and LTM (could rehearse info with IM but couldn't form LTM)
&
Procedural and Semantic memory (performed tasks with procedural mem. but couldn't learn new facts with semantic mem.
199
What one-word response is NOT responsible for the sin of transience?
Decay - because time is not responsible for memory decay its the info that occurs in the time that elapses is
200
What is Korsakoff syndrome?
Alcoholism can trigger this syndrome which can result in anterograde amnesia
201
Slow emotional route ('high road') process order in the body
Sensory organ -> thalamus - > cortex-> amygdala
202
Fast emotional route ('low road') process order in the body
Sensory organ -> thalamus -> amygdala
203
Which emotions (basic or complex) are more likely to take the 'low road' and why?
Basic emotions (fear, likes) are more likely because they do not require cognitive appraisals of the situation like complex ones do
204
Mood vs. Emotion
Long-lasting, less-intense states, not affected by specific object or event.
VS
Short-lived feelings we have towards a specific object or situational event (elicited by rewards and punishers)
205
What is the role of antecedent stimuli?
signals whether you'll get a reinforcer or a punisher for responding
206
4 things that emotions generally have temporary changes in:
Hormones or physiology
Behavior, including thinking or feeling
Facial expression
Sense perception
207
Why is it best that each emotion is a different adaptation?
Serves a different evolutionary purpose
208
What are the three principles of emotion?
Serviceable habits
Antithesis
Direct action
209
What is the first principle of serviceable habits emphasizing?
The way emotions are expressed serves a purpose in non-human animals but not people.
210
Explain the second principle of antithesis
Opposite emotions have opposite bodily expressions.
211
Explain the third principle of direct action of the excited nervous system on the body
Emotions result in perceivable changes in the nervous system.
212
What is the basic emotion theory?
Distinct emotions and their associated cognitive, physiological, and motor responses unfold over time in a very predictable pattern without attention or intention.
213
Explain the James-Lange theory of emotions
People perceive a stimulus, express the emotion the stimulus evokes, and then identify their emotion.
214
Why do we understand that we're experiencing different emotions?
Because of their associated physiological effects.
215
Describe the Cannon-Bard thalamic theory of emotions
People perceive a stimulus and then simultaneously express the emotion and identify their emotion.
216
Name the three observations of evidence for the importance of the thalamus in governing emotions
a) rage is evoked by surgically removing the cerebrum in front of the thalamus but disappears when the thalamus is removed.
b) tumors on different sides of the thalamus produce different emotions
c)anesthesia or impairment produces unregulated crying or laughing
217
Difference between the James-Lange and Cannon-Bard theories of emotion
Events surrounding the expression of emotion occur sequentially within the James-Lange theory but simultaneously and with the help of the thalamus for Cannon-Bard
218
Paul Ekman and the 4 universal emotions
2016 - happy, anxious, surprise, disgust
219

How do animals usually respond to stress?
By emitting distress vocalizations
224
What are frustrative events and who recognized it?
Situations in which rewards are not as quickly available as they once were or are omitted entirely, thereby leading to frustration. Abram Amsel (1992)
225
Pavlovian Conditioning helps prepare us for what two needs?

How long does it take for you to digest food after you taste it?
4-6 HOURS
228
According to Al-Shawaf (2016), what does hunger do to people?
Regulates their systems and makes them turn away from engaging in any other activity or prior engagements
229
Occasion Setters
An internal or external stimulus that signals the relationship between a response and an outcome -an event telling the organism that something is about to occur
230
Interoceptive Stimuli
A type of stimuli that come from within our bodies to indicate a change from one state to another. We experience a private sensation that others cannot see, feel, touch, etc. and respond to it.
231
Stimulus Substitution
Type of conditioning in which an animal responds to the conditional stimulus as if it were interchangeable with the unconditional stimulus
232
Energy budget
An animal needs to consume a specific amount of calories in a day to survive
233
Exteroceptive Stimuli
Type of stimuli that come from outside our bodies to indicate a change from one state to another. We perceive a stimulus that others can also see, hear, feel, touch, etc
234
Signal Substitution
Conditioning in which an animal responds to an artificial conditional stimulus as if it were interchangeable with an unconditional stimulus
235
What does signal substitutions usually have to have in order to evoke a response?
Supernormal Stimuli
236
Supernormal Stimuli
Any stimulus that elicits a response more strongly than the stimulus for which it evolved
237
Why do we salivate before we start eating?
It helps with digestion - dilutes acids. Usually obese people salivate more than healthy weight people
238
Belongingness
Type of learning in which some cues are easier to condition to specific signals than others for enhanced survival. The cue, behavior, and consequence "belong" together.
239
What attribute did women and men think that they wanted in long-term partners and what trait did they most consistently choose in long-term partners?
Faithfulness; sense of humor
240
What type of men do women usually prefer when they are ovulating?
Masculine and aggressive men
241
Hermaphrodites
Animal that can either be male (with sperm), or female (with eggs), in a sexual encounter
242
Gender Ratio Hypothesis
Describes how the animals decide whether to contribute sperm and when to receive it.
More advantageous to fulfill the female role for first part of reproductive period
243
Pheromones
type of chemical signal to indicate the reproductive status of a potential partner
244
Which species can use pheromones to recognize a potential mate and to facilitate attraction?
Male rats
245
Coolidge Effect
An animal has multiple mate-pairings with the same partner, loses interest in that partner, and experiences renewed sexual interest in a new partner
246
Rivalry Sensitivity Hypothesis
Women focus on rivals in their partner's immediate vicinity while men focus on their partner if a rival in nearby
247
Drive-Reduction Theory
Need is determined by a combination of learning and a person's physiology, and need intensity will be reflected in the intensity of responding
248
What is the pop-out phenomenon, in regards to salience?
An image or object that stands out more than the rest of the picture
249
What is the purpose of a dichotic listening task?
To determine how much unattended information is being processed
250
What structures in the brain does the circadian rhythm (internal clock) influence?
The SCN (suprachiasmatic nucleus) sends signals to several regions of the brain, among them the pineal gland. In response to the light/dark cycle, the pineal gland secretes melatonin. Melatonin levels are highest right before bed and seem to signal to the brain that light is absent.
251
Inactivity theory of Sleep
based on the concept of evolutionary pressure where creatures inactive at night were less likely to die from the predation of injury in the dark, thus creating an evolutionary and reproductive benefit to being inactive at night
252
Energy Conservation theory of sleep
reduce a person's energy demand during part of the day and night when it is least efficient to hunt for food
253
Restorative Theory
sleep allows for the body to repair and replete cellular components necessary for biological functions that become depleted throughout an awake day
254
Brain Plasticity Theory of sleep
ability of the nervous system to change its activity in response to intrinsic or extrinsic stimuli by reorganizing its structure, functions, or connections.
255
Dishabituation
when attention is redirected to the stimulus after there has been a change in the nature of the stimulus
256
Second-order Conditioning
phenomenon whereby a conditioned stimulus (CS) acquires the ability to elicit a conditioned response (CR) without ever being directly paired with an unconditioned stimulus (US
257
Classical Conditioning and aiding in substance abuse
Familiar cues associated with the drug
258
What is shaping and when is it necessary?
involves selecting and reinforcing more complex responses that look like the response you want while extinguishing simpler forms of the target response.
Necessary when prior forms of action to get to a certain target weren't working
259
Primary vs Secondary Reinforcer
primary reinforcer is biological stimulus causing involuntary reflex while secondary reinforcer is conditioned stimulus causing learned behavior
260
What factors increase the chance observational learning will occur? Who came up with this idea?
Reward makes the action more desirable
Bandura (1965)
261
How systematic desensitization involves classical conditioning?
Systematic desensitization is a type of exposure therapy based on the principle of classical conditioning. It was developed by Wolpe during the 1950s. This therapy aims to remove the fear response of a phobia, and substitute a relaxation response to the conditional stimulus gradually using counter-conditioning.
262
What is the stroop effect and how does it demonstrate that memory can be automatic?
Colours and words. List had colours matching the words and a list had colours not matching the words. Seeing what you read first
263
Clive Wearing's case and what we learned about memory
Retrograde and anterograde amnesia - could only remember 30 sec
He contracted herpes simplex encephalitis, a disease that caused swelling of brain tissue resulting in damage to his hippocampus.
It taught us hippocampal dependent formation of long term memory
264
What is flashbulb memory?
Vivid, long-lasting memories for events that are both surprising and particularly significant. Ex. Assassination of the President displayed on the news
265
How do moods affect memory?
You remember happy events when you are happy and the same goes for sad mood.
266
Overcoming TOT state
Don't dwell on it. Stress less. Clench fist
267
Two-Factor Theory of Emotion
Schachter and Singer's (1962) Two-Factor Theory of Emotion suggests that physiological arousal determines the strength of the emotion, while cognitive appraisal identifies the emotion label. So, in this theory, the “two-factor” represents physiological change and cognitive appraisal change
268
Does emotion and cognition interact?
Strong emotions affect the way our mental state can be. And it affects behavior
269
What role does the amygdala play in emotion?
The amygdala is responsible for the perception of emotions such as anger, fear, and sadness, as well as the controlling of aggression. The amygdala helps to store memories of events and emotions so that an individual may be able to recognize similar events in the future
270
Different schedules of reinforcement, and who created them?
Continuous - responses reinforced every time they occur
Intermittent responses reinforced occasionally
Extinction - response no longer reinforced - decreasing probability of the behavior
Jenkins (1962)
