Purpose of the split-brain surgery
Reduce freq. and severity of seizures from epilepsy
Negative side effects of the split-brain surgery
Portions of brain can no longer communicate with each other. Results, left hand may put down a book that the reader is actually reading with interest
Define Hemispheric Specialization
Refers to the idea that the left and right brain have different functions
What happens in split-brain patients with contralateral processing?

Refers to idea that some stimuli in the environment capture attention because of their physical properties
Define Attentional Capture
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
Explain the Dichotic Listening Task
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.
Define Automaticity
fast, effortless processing of info without conscious thought. Ex. Typing on a keyboard without looking, walking down the street
What is inattentional blindness? (Hint: distracted)
tendency to miss changes to some kinds of info when your attention is engaged elsewhere.
Describe the Flicker Task (HINT: inattentional blindness)
Participants are shown two variations of the same picture, usually with one difference between the images. First image presented briefly followed by a white screen, then they are shown second version of image followed by another white screen.
Define intentional change detection
attention task that requires participant to actively search for a change made to the stimulus.
What is inhibition with information?
Process of actively reducing processing of some info while the brain attends to a specific task
What is a Subliminal Stimulus?
Sensory stimulus that is processed, but does not reach the threshold for conscious perception
Subliminal Process, what is it?
Info we don’t consciously detect.
Subvisual/Subaudible messages - messages presented too quickly for brain to perceive in conscious awareness.
Not salient enough to receive extra attention or processing
What happens to patients who suffer from damage to the right inferior parietal lobe of the cortex?
They experience unilateral neglect. Ex. Only apply makeup to half their face, only draw right side of an image
What is the main cause of ADHD and where is the location of the damage?
Genetics influence the disorder, and the damage is found in the prefrontal cortex.

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
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)
What does desynchrony in Beta Waves tell you?
Different neuronal circuits in the brain are actively processing info
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
What is slow-wave sleep?

Shows how much time we spend in each stage of sleep throughout the night.
How many stages of sleep are there and what are their main components?
Stage 1 - Theta Activity
Stage 2 - Sleep spindles and K complexes
Stage 3 - Slow wave sleep
Stage 4 - REM Sleep
Stage 1 Sleep - Theta Activity
Alpha (8-12 Hz) to theta waves (5-8 Hz)
Light sleep
Causes body jerks when woken, may not even know you fell asleep
Stage 2 - Sleep Spindles and K-Complexes
Some theta activity
Bursts of activity 2-5x/min (sleep spindles)
Excitation followed by neural inhibition about once per min in preparation for deeper sleep (K-complexes)
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
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)
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)
When the brain is deprived of REM for days at a time what happens?
The brain tries to enter into REM more quicky and spend more time there.

Sigmund Freud
What did Sigmund Freud believe?
Unconscious processes are a great contributor to our behavior
What stage do nightmares usually occur in?
Stage 3 -Slow-Wave sleep (able to relay the dream usually)

hypothesis about dreaming that suggests that dreams do not serve a purpose, but rather are the consequence of other processes that occur during sleep.
What is the Evolutionary Hypothesis of Dreams?
suggests that dreams have biological significance
What is Predation?
example of an ancestral threat, which dreams may have evolved to help us model how to solve
Define Dyssomnias
Problems with quality of sleep
Define Parasomnias
Disturbances that occur during sleep
Conditioned insomnia
insomnia that occurs with cues that associated with falling asleep, like your bed, instead cause feelings of anxiety surrounding inability to fall asleep

people are not acting out a dream, but rather while deeply asleep they are able to conduct behaviors as if they were awake.
Occurs during SWS
What are Zeitgebers?
Cues from environment that set bio clocks
Circadian Rhythms
Tells body when to sleep and wake
Suprachiasmatic Nucleus (SCN)
structure in brain, next to optic chiasm, sets circadian clock for body
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
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.

Term for something you are born knowing how to do i.e. Babies crying when they are hungry
Innate Skills
What decade did Ivan Pavlov conduct the dog salivation experiment?
In the early 1900s
Define Pavlovian Conditioning
Seemingly insignificant event signals an important event.
What is the main role that a conditional stimulus plays?
Provides information about the presence or absence of an unconditional stimulus
What is a conditional response (or reflex)?
Learned response that occurs to the conditional stimulus in preparation for the US
Stimulus is anything in the environment we can (3):
Detect
Is measurable
Can evoke a response or behavior
Why can we start with an US with almost every behavior?
Biologically important EVENT requires no conditioning to affect our behavior
What is an UR (Innate Reflex)?
Biologically important RESPONSE occurs because of US
In Pavlov’s experiment what were the different factors? Name the CS, CR, US, UR
CS - Lab Coat (went from neutral to CS)
CR - dog salivation
US - Food
UR - dog salivation
What is a main purpose of Pavlovian Conditioning?
To change a neutral stimulus into something that elicits a response
When does the CR occur?
Occurs in preparation for and prior to the US
Define Excitatory Conditioning
CS indicates that a US will occur.
3 ways a CS is presented before the US (look at notes for examples)
Short-delayed - occurs within secs
Long-Delayed - been there for a while
Trace Conditioning - min. or hours after CS has stopped
What category of conditioning do Simultaneous and Backward Conditioning fall into?
Inhibitory Conditioning - CS indicates that no US will occur
Simultaneous conditioning
CS and US occur at the same time, overlapping completely
Backwards Conditioning
US occurs before CS
Garcia and Koelling (1996) and what did they study?
Flavour conditioning with rats (taste aversion)
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
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.
Attainment by an individual of new behavior, info, or skills
Acquisition
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
Effect in which an animal notices differences between objects and responds to the objects as though they were different
Stimulus Discrimination
What is Higher-Order Conditioning
Conditioning procedure in which an already-conditioned signal is paired with a neutral stimulus or currently meaningless event.
John B. Watson’s Perspective
Environment is important to behaviorism. Psychology could be measured by constructs like behavior, without considering subconscious thoughts or feelings.
Who developed a therapeutic treatment for phobias called, “Systematic Desensitization”?
Joseph Wolpe (1958)
What is Operant Conditioning (instrumental)?
Consequences from behavior. Choosing how to react based on previous experiences as well
Who “paved” the way for the study of behaviorism? (Cat escaping the box with trial and error)
Thorndike
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
What law did Thorndike develop?
The law of effect - how we learn about situations and behaviors leading to something we like
Satisfaction (stamping in)
Learning behaviors that lead to something we like; learn to repeat that behavior
Discomfort (stamping out)
not associating our behaviors with situations that lead to something we don’t like. Learn not to repeat them
Who found radical behaviorism - philosophy saying to treat thinking and feeling like any other behavior
B. F. Skinner
What changes did B.F. Skinner make to Thorndike’s idea of Operant conditioning?
Changed “operant” to “instrumental”.
And included CONSEQUENCES as part of what we learn about behavior
Anything in physical environment that we can detect and tells us something about what the consequences of our actions will be
Antecedents
Stimuli that can increase or decrease the probability of future behavior
Consequences
Differential VS Nondifferential Consequences
SPECIFIC consequence given for picking certain item
VS.
NO difference in consequence even though different actions or items are being used
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.
If-then rule, if you do this then this will happen is called what?
Contingency - occurs before a behavior
What is it called when a consequence INCREASES the probability of that behavior occurring again?
Reinforcement
Consequences DECREASE the probability of that behavior happening again term?
Punishment
List the 4 Contingency procedures (look at examples and explanations from notes)
Positive Reinforcement
Positive Punishment
Negative Reinforcement
Negative Punishment
What is main purpose of contingency and the 4 procedures?
To determine if the consequence will be produced or removed in the future
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
What operant process did Skinner believe had the greatest influence on behavior?
Positive Reinforcement
Explain Operant Extinction
Behavior previously reinforced now produces no consequence and goes away; the response is not reinforced and decreases
3 Behavioral Effects of Extinction
Extinction burst - temp. increase in responding
Emotional and Aggressive responding
Responding eventually stops
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
What hormone does the Pineal gland produce?
Melatonin - sleep-inducing
What is Adenosine and what does it do?
When the body runs out of fuel this chemical inhibits neural activity and causes drowsiness
Benefit of exposure to sunlight right in the morning
Decreases melatonin production
Production of melatonin cannot be triggered in what individuals?
Blind individuals
Two ways to ‘reset our clock’ if we have jet lag
- Exposure to light (decrease melatonin production)
- Take melatonin pill - helps us fall asleep to get back on schedule
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
Why do older people not sleep as much?
They no longer have the GH released from the pituitary gland
What are the 4 types of learning?
Habituation
Classical Conditioning
Operant Conditioning
Observational Learning
What happens in Habituation?
Respond less once stimulus is familiar. Not surprised by it anymore
Demonstrates memory
Ex. Can’t feel shoes on your feet
In regards to Habituation, what happens as time goes on?
Partial recovery
THEN
Full recovery
Are Pavlovian and Classical Conditioning the same?
Yes. They are an association between a neutral stimulus and a meaningful stimulus
What is a taste aversion?
Getting sick from a certain type of food and from then on associating the food with that bad experience
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)
Difference between Classical and Operant Conditioning
Classical - forms association between 2 stimuli
Operant - forms association between a behavior and consequence
Primary VS Secondary Reinforcers
Primary - unlearned, rooted in biology
Secondary - learned through association with a primary reinforcer
What are the 4 types of intermittent reinforcement? (FVFV)
Fixed Ratio (FR)
Variable Ratio (VR)
Fixed Interval (FI)
Variable Interval (VI)
Fixed Ratio VS Fixed Interval
Reinforces after given number of correct responses Ex. Free coffee after buying 9
VS
Reinforces for first correct response after set time period Ex. Mail arrives at a certain time everyday
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
What is Intermittent (partial) reinforcement?
Reinforced sometimes when behavior occurs
Which reinforcement schedule would work best for acquisition?
Continuous - in learning the skill they can associate a behavior with a response
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.
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
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)
What was the early version of the Modal Model of the Mind?
Sensory input -> Sensory Stores -> STM -> LTM
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
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
What two people modified the Memory model?
Baddeley and Hitch (1974)
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
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
What is Iconic Memory and who created the idea?
Sperling (1960)
Relation to visual sensory input, like memorizing letters. First ones are easiest to remember usually
LTM - Declarative (explicit)

Depth of Processing list from shallow to deep
Orthographic (memorizing definitions), Phonetic (rhyme relationships), Semantic (meaning relationships)
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)
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
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)
How long will sensory memory hold onto information?
Long enough for us to stitch one moment of our experience to the next.
Iconic memory VS Echoic memory
Fleeting afterimages VS lingering neuronal activity called an echo
Other names for Immediate memory
STM OR WM
Immediate memory and the three main properties
Representation, duration, and capacity
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
What are semantic memories?
Contents relate to specific facts and pieces of meaningful info not based on personal experience
Deep VS Shallow Processing
Encoding new info through meaningful connections to existing knowledge
VS
Encoding info based only on its surface characteristics

Were inanimate or animate objects easier to remember for humans?
Animate - more salient. Brains have evolved to pay attention to it
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
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
Transfer Appropriate Processing (Lockhart 2002)
Observation that engaging in similar processes at both encoding and retrieval tends to enhance recall on final test
Explicit VS Implicit Memory
Remembering occurring consciously - trying to recall info
VS
Remembering that occurs without conscious realization
Who created the errors of omission and commission?
Daniel Schacter (2002)
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
Name the three errors of omission
Transience, absent-mindedness, and blocking
What is Transience?
We may be unable to retrieve info - forgotten due to interference of info being processed currently
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
Absent-mindedness
Description of how memories sometimes are simply unavailable because of a failure to encode them
Blocking
In some cases, not enough distinctive cues are available to help us recover a specific memory
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 -
Misinformation Effect
misleading info alters subsequent memory, typically an eyewitness account
Schema (part of sin of Bias)
Highly organized Knowledge structure that contains many pieces of specific info. May lead to over-generalization
Persistence
Description of how memories are sometimes retrieved when they are not wanted
What is Hyperthymesia?
Medical condition leading to near perfect autobiographical recall
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)
Why did Henry Molaison have his hippocampus removed?
To stop his severe epileptic seizures. Had both types of amnesia
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.
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
What is Korsakoff syndrome?
Alcoholism can trigger this syndrome which can result in anterograde amnesia
Slow emotional route (‘high road’) process order in the body
Sensory organ -> thalamus - > cortex-> amygdala
Fast emotional route (‘low road’) process order in the body
Sensory organ -> thalamus -> amygdala
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
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)
What is the role of antecedent stimuli?
signals whether you’ll get a reinforcer or a punisher for responding
4 things that emotions generally have temporary changes in:
Hormones or physiology
Behavior, including thinking or feeling
Facial expression
Sense perception
Why is it best that each emotion is a different adaptation?
Serves a different evolutionary purpose
What are the three principles of emotion?
Serviceable habits
Antithesis
Direct action
What is the first principle of serviceable habits emphasizing?
The way emotions are expressed serves a purpose in non-human animals but not people.
Explain the second principle of antithesis
Opposite emotions have opposite bodily expressions.
Explain the third principle of direct action of the excited nervous system on the body
Emotions result in perceivable changes in the nervous system.
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.
Explain the James-Lange theory of emotions
People perceive a stimulus, express the emotion the stimulus evokes, and then identify their emotion.
Why do we understand that we’re experiencing different emotions?
Because of their associated physiological effects.
Describe the Cannon-Bard thalamic theory of emotions
People perceive a stimulus and then simultaneously express the emotion and identify their emotion.
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
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
Paul Ekman and the 4 universal emotions
2016 - happy, anxious, surprise, disgust
Describe the term action unit
Each emotion has a facial expression that we can detect involving movement of the eyebrows, nose, mouth, cheeks, and eyes

Activity in the amygdala and the prefrontal cortex accompany the emotional response to what?
Stress
How do animals usually respond to stress?
By emitting distress vocalizations
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)
Pavlovian Conditioning helps prepare us for what two needs?
Fornication and Eating in the presence of specific eliciting stimuli
Orsosensory stimuli
Flavour and texture sensations in the mouth
How long does it take for you to digest food after you taste it?
4-6 HOURS
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
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
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.
Stimulus Substitution
Type of conditioning in which an animal responds to the conditional stimulus as if it were interchangeable with the unconditional stimulus
Energy budget
An animal needs to consume a specific amount of calories in a day to survive
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
Signal Substitution
Conditioning in which an animal responds to an artificial conditional stimulus as if it were interchangeable with an unconditional stimulus
What does signal substitutions usually have to have in order to evoke a response?
Supernormal Stimuli
Supernormal Stimuli
Any stimulus that elicits a response more strongly than the stimulus for which it evolved
Why do we salivate before we start eating?
It helps with digestion - dilutes acids. Usually obese people salivate more than healthy weight people
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.

type of chemical signal to indicate the reproductive status of a potential partner
Which species can use pheromones to recognize a potential mate and to facilitate attraction?
Male rats
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
Rivalry Sensitivity Hypothesis
Women focus on rivals in their partner’s immediate vicinity while men focus on their partner if a rival in nearby
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
What is the pop-out phenomenon, in regards to salience?
An image or object that stands out more than the rest of the picture
What is the purpose of a dichotic listening task?
To determine how much unattended information is being processed
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.
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

Restorative Theory
sleep allows for the body to repair and replete cellular components necessary for biological functions that become depleted throughout an awake day
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.
Dishabituation
when attention is redirected to the stimulus after there has been a change in the nature of the stimulus
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
Classical Conditioning and aiding in substance abuse
Familiar cues associated with the drug
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
Primary vs Secondary Reinforcer
primary reinforcer is biological stimulus causing involuntary reflex while secondary reinforcer is conditioned stimulus causing learned behavior
What factors increase the chance observational learning will occur? Who came up with this idea?
Reward makes the action more desirable
Bandura (1965)
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.
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
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
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
How do moods affect memory?
You remember happy events when you are happy and the same goes for sad mood.
Overcoming TOT state
Don’t dwell on it. Stress less. Clench fist
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
Does emotion and cognition interact?
Strong emotions affect the way our mental state can be. And it affects behavior
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
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)
