Q

Pavlov’s Discovery

A
  • (basic of classical conditioning)
  • while studying digestion in dogs. Ivan Pavlov found that salivation was eventually triggered by neutral stimuli that predicted that arrivial of food such as,
  • -> just seeing the food or dish
  • -> seeing the person who brought the food
  • ->just hearing that person’s footsteps

Q

Acquisition

A

refers to the initial stage of learning conditioning

  • As the CS and US are paired, the strength of the CR grows
  • Timing is important - the Cs should appear roughly half a second before the US for learning to occur

Q

A cycle of reinforcement: temper tantrums

A

what happens if the parent gives into a temper tantrum and abides by the child’s demands??
The child’s tantrum is positively reinforced, so the tantrums will get stronger and more frequent
-The parent’s ‘giving in’ behaviour is negatively reinforced, so the parent will give in sooner and more often

Discrimination

A

refers to the ability to become more and more specific in what situations trigger a response

  • shaping can increase discrimination, if reinforcement is only delivered when certain discriminating stimuli are present
    (example: pigeons, seals, and manatees can respond to specific shapes, colours and categories of pictures).

Amy won jackpot on the slots, bells and whistles were going off all around her in the casino. Now, whenever she sees a slot machine with lots of bells and whistles, she feels a rush of excitement
Joey’s chore growing up was dishes. Every night after dinner, Jpey’s parents would sit down to watch the news while he was supposed to tend dishes. But every night, Joey was delayed in starting the dishes. He would get scolded and feel bad inside, and this usually happened right after the news began with its jaunty tune. Years later, whenever Joey hears the tune from the news, he feels bad inside

Q

short term memory

A

-temporarily holds a limited amount of information

103
Q

How is information represented? (short term memory )

A

Various forms of representations/memory codes
-images (visual), sounds (phonological), meaning (semantic), physical action (motor), etc…
Form of memory code doesn’t necessarily correspond to form of original stimulus
–>example: sound-alike errors on memory tests for visually presented stimuli

104
Q

whats the capacity of short term memory

A
  • magical number 7, +- 2 (Miller, 1956)
  • Can increase short-term memory by Chunking
  • ->combining individual items into larger units of meaning
105
Q

whats the duration of short term memory

A

-information is rapidly lost unless we actively do something with it (rehearsal)

106
Q

Long term memory ( more detail)

A
  • Library of durable stored memories

- Storage capacity unlimited, and information can last a lifetime

107
Q

What is the distinction between short-term and long term

A
  • seen in ‘serial position effect’
  • participants are read a list of unrelated words and asked to recall as many as they can
  • researchers look at memory as a function of each word`s position in the list
108
Q

Serial Position effect

A
  • Find U-shaped pattern as a function of position in list

- ->superior recall of early (primary effect) and most recent (recency effect) words

109
Q

Primacy effect:

A

information transferred to long-term memory

-effect diminished if increase rate of presentation

110
Q

Recency effect

A
  • information still in short-term memory

- ->effect diminished if time delay before recall

111
Q

-Serial Position effect

what about the dip in the middle of the curve?

A

Caused by two different mechanisms

  • proactive interference
  • Retroactive Interference
112
Q

Proactive interference

A

-First information learned occupies memory resources, leaving fewer resources to remember later, incoming information

113
Q

Retroactive interference

A

-most recently learned overshadows old memories that have not yet made it into LTM

114
Q

Working memory model

A

-Gives us a mental work-space in which we store actively process information
-A model of short term memory that includes multiple memory components:
4 components
phonological loop
visuspatial sketchpad
episodic buffer
central executive

115
Q

phonological loop

A

-auditory storage

116
Q

-->Episodic 
Non-declarative 
-->Procedural  
-->Conditioning
120
Q

Declarative memory (aka explicit memory)

A

-facts and experiences that we can consciously know and recall
two subtypes:
episodic memories
Semantic memories

121
Q

Episodic memories

A

memories for personal experiences that seem to be organized arounnd ‘episodes’ and are recalled in the first-person

122
Q

Semantic Memories

A
  • memories that contain factual knowledge

- acquired through effort full processing (studying, rehearsing, thinking etc… )

123
Q

Non declarative memory (aka implicit memory)

A

-include actions or behaviours that we can remember and preform without awareness
-include actions or behaviours that we can remember and perform without awareness
-acquired through automatic processing (no effort made to form a memory)
two subtypes
Procedural memories
Classical Conditioning

124
Q

Procedural Memories

A

motor memories for patterns of muscle movement

125
Q

Classical Conditioning

A

When a previously neutral stimulus produces a response because it has been paired with a stimulus that produces a response

126
Q

Why is the brain not like a hard drive

A
  • Memories are not isolated files
  • ->They’re in overlapping neural networks
  • The storage capacity does not get full
  • ->it gets more elaborately rewired and interconnected
127
Q

what did Lashley (1950) show

A

that rats that had learned a maze retained parts of that memory, when when various small parts of their brain were removed

128
Q

Long-term potentiation (LTP):

A

-The enduring increase in connectivity and transmission of neural signals between neurons that fire together

129
Q

Consolidation

A
  • A process of converting short-term memories into long term memories in the brain.
  • -> cellular consolidation = when presynaptic cell is more likely to stimulate a specific postsynaptic cell (or group of cells), due to repeated firing
130
Q

Retrograde Amnesia

A

The inability to remember what was already known at the onset of amnesia (retrieve memory of the past)

131
Q

Anterograde amnesia

A
  • the inability to form new long-term explicit memories
  • implicit memory intact
  • -> Could still learn how to get places (automatic processing), and could learn new skills (procedural memory)
132
Q

More about H.M

A
  • Anterograde amnesia following removal of hippocampus
  • LTM largely intact - could recall events from his past
  • could form new implicit memories - learn new skills, although no memory of this
  • Problem specific to transferring declarative/explicit memories from STM to LTM
133
Q

Encoding

A

The process of transforming sensory and perceptual information into memory traces
-More effective encoding into LTM = greater likelihood of retrieval

134
Q

Retrieval

A

the process of accessing information for LTM and returning it to STM

135
Q

Maintenance Rehearsal

A
  • Rote repetition of information

- not an optimal method

136

-Focuses on information’s meaning
-may involve: organizing, understanding, applying to one’s life, relating to already learned concepts ,using imagery
Self reference effect

137
Q

Self-reference effect

A

relating material to ourselves helps encoding and retention

138
Q

Levels of processing

  • Depth of processing increases recall
  • Horse
  • ->Structural
  • ->phonemic
  • ->semantic
139
Q

Retrieval Cues

A

_stimuli that lead to activiation of information stored in LTM
-Multiple Cues lead to better retrieval
–>involves deeper processing
-Self generated cues lead to better retrieval
-Retrieval of distinctive events
–>greater chance of etching vivid, clear, long temr me memories
(weddings, romantic encounters, births, deaths)

140
Q

Context-dependent memory

A
  • the context of where learning occurred can also become part of the memory and used as a retrieval cue
  • We retrieve a memory more easily when in the same context as when we formed the memory.
141
Q

State-dependent memory

A

-ability to retrieve is better when internal state matches that at encoding

142
Q

Mood-dependent Learning

A

Tend to recall information or events congruent with current mood

143
Q

why are emotional memories more likely to be retained

A
  • emotions trigger an increase in stress hormones

- stress hormones trigger the amygdala

144
Q

What does the amygdala do in emotional times

A

increased the hippocampus’ job of consolidating the memory

-engages the frontal lobes and basal ganglia to ‘tag’ the memory as important

145
Q

Flashbulb Memories

A
  • Extremely detailed and vivid memories about events and the conditions surrounding how one learned about the event
  • Not necessarily accurate!
146

  • ->more memory associations with multiple codes
  • leads to more retrieval cues that could be used later
153
Q

Schema

A

organized clusters of memories that constitute one’s knowledge about events, objects and ideas

154
Q

Points about schema (4)

A

are a product of our culture and experience

  • helps us understand and organize incoming information
  • ->vague laundry paragraph
  • involved in all stages of memory
  • may cause memory errors, particularly for uninteresting events that do not fit our schemas
  • ->examples: little old lady driving a mustang convertible
155
Q

how is Memory is a constructive process

A
  • memories are imagined, selected, changed, and rebuilt
  • memories are altered every time we ‘recall’ (actually, reconstruct) them
  • memories are altered again when we reconsolidate the memory
  • later information alters earlier memories
156
Q

False Memory

A

remembering events that did not occur, or incorrectly recalling details of an event
-the more we imagine an event, the more it will see, like a real memory
ex. have you ever discovered that one of your childhood memories wasn’t really your own?
it was from a book or movie, or it was from a story that happened to someone else, or it was from a dream, etc…

157
Q

The misinformation effect

160
Q

how to recover memories of abuse

A
  • abused memories are most likely to be a memory “burned in” than forgotten
  • ->also tend to avoid thinking about them , so memory may fade over time
  • Accidental reminders can activate a forgotten memory for minor events
  • Actively searching for memories can create detailed memories that feel very real
161
Q

how to recover memories of abuse continued

A
  • while true repressed or recovered memories may be rare, unreported memories of abuse are very common
  • there is no clear way to tell when someone actually been abused
  • an implanted, constructed memory can be just as troubling as a memory from direct experience

167
Q

How to Measure Infant Behaviour

A
  • can’t just ask an infant about how they experience the world
  • competence-performance distinction:
  • An individual may fail a task not because they lack those abilities, but because they were unable to show those abilities
  • ->thus, what we know about infants is only as good as our tools for measuring their abilities
168
Q

Habituation procedure (2 main points)

A

-used to determine if the infant can be detect the difference between two stimuli
Ex: can an infant hear the difference between a male and female voice
–>present male voice until infant shows boredom in a response you’re meaning (this is habituation)
-change the stimulus to a female voice
-if the infant detects the change, then they should show a coinciding change in response at that exact moment (this is dis-habituation)
-another example (can infant distinguish blue from green)

169
Q

Evoked potentials

A
  • used to determine if an infant can detect a stimulus at all
  • measure an infant’s brain waves through electrodes while you present a stimulus
  • ->if the infant can detect the stimulus, then the pattern of brain waves will change
170
Q

High-amplitude sucking method:

A
  • used to determine what stimulus an infant prefers

197
Q

What did Piaget Believe

A

that our understanding of things in our world is modified in two ways
-Assimilation
-Accommodation
Believed in nature and nurture

  • ->Formal logic is a smaller part of cognition, even for adults,
206
Q

Vygotsky

A

-Social interaction is important for development
-children learn thinking skills by internalizing language from others and developing inner speech
Development viewed as building on a scaffold of mentoring, language, and cognitive support from parents, siblings, teachers, and others
-ideal level of instruction is the zone of proximal development -child can’t quite do alone but can with guidance of teacher/helper

207
Q

6. parent leaves
7. stanger enters and offers comfort
8 Parent returns, comforts, engages baby with toys

211
Q

define Secure attachment

A
  • most children fall in this category

  • greets mother warmly upon her return and seeks her comfort
212
Q

what are the 3 insecure attachment types

A
  • anxious/resistant type
  • aviodant type
  • disorganized type
213
Q

Anxious/resistant type

A
  • infant clings to mother and is less likely to explore the environment
  • upset when mother leaves and likely remains upset when she returns
214
Q

Aviodant Type

A
  • infant shows very little distress when mother leaves and seems to ignore her
  • may be sociable with or ignore stranger
215
Q

Disorganized Type

A
  • infant seems to both approach and avoid mother

- may act dazed or freeze

216
Q

what causes the different attachment

A
  • Infant’s temperament a minor influence
  • parenting behaviour is key factor
  • ->sensitive and responsive parenting leads to secure attachment
  • ->inconsistent, impatient, or overstimulating care giving leads to insecure attachments
  • Training in sensitive responding for parents increases the rates of secure attachment
217
Q

father is a caregiver

A
  • many studies of the impact of parenting focused on mothers
  • correlational studies show a strong relationship between paternal involvement in parenting and the child’s academic success, health, and overall well-being
218
Q

Deprivation of attachment (behaviours)

A
  • strong capacity for recovery if deprivation is over the first 2 years of life and then child is put in a good home
  • Less chance of recovery with longer deprivation period
  • ->Difficulty forming attachments
  • ->increased anxiety and depression
  • ->increased aggression

why do teens struggle with self-control

A

frontal lobes
also undergo a wave of synaptic pruning, during which
relatively unused synaptic connections are broken, leaving
a more efficiently functioning brain.

KOHLBERG’S MORAL DEVELOPMENT: three general stages

A

Preconventional morality
Conventional morality
Postconventional morality

229
Q

Carol Gilligan (1982)

A

suggested
that females base moral decisions on a standard of caring
for others , rather than the “masculine” emphasis on standards
of justice and fairness that Kohlberg emphasized.

230
Q

social intuitionist model

A

which argues that
moral judgments are guided by intuitive, emotional reactions.
Generally, we make a decision based on our “gut
reaction” and then afterwards we construct the arguments
that support our judgments

231
Q

Q

The First Horseman—Criticism

A

Complaining
about what’s wrong in a relationship is okay, but stay
focused on what you want to see change. Once the
complaint shifts from the problem itself to how it’s all
your partner’s fault, criticism is rearing its ugly head.
Watch out for words like “always” and “never.” This fi rst
horseman is often followed by . .

249
Q

The Second Horseman—Defensiveness

A

“It’s not
my fault! You do x, y, and z too!” When you feel attacked,
it’s natural to want to defend yourself, but it undermines
communication and turns a problem-solving dialogue
into a war. Instead of defending, take responsibility for
your part of the problem, let your partner know you’re listening and you’re open to
what your partner is saying, and
try to find solutions together
rather than just “proving” it’s
not all your fault.

250
Q

The Third Horseman—

Contempt:

A
“If you were my
husband, I’d poison your coffee!”
“Yeah, well if you were
my wife, I’d drink it!” Although
this is a joke, contempt is basically
relationship poison. Contempt
creeps in when one
partner feels superior to the
other, feels that what upsets the
other is not that big of a deal
and engages in name-calling,
sarcastic retorts, and eye-rolling
during a confl ict. To avoid contempt,
make the choice to focus
on all those things you love and
appreciate about your partner, and try to understand the
concerns from your partner’s perspective, not yours. Just because something seems like “no big deal” to you, it is to them, and they have good reasons for their reactions,perhaps reaching into painful experiences they’ve had in the past. Instead of judging them, practice empathizing,and instead of focusing on how much they have failed,focus on how hard they are trying.
251
Q

The Fourth Horseman—Stonewalling

A

This one
seems straightforward—the stony silence, one-word
answers, going cold and acting like you don’t care. What’s
not straightforward is realizing that what causes stonewalling
is often that the person feels so emotionally
overwhelmed that she or he doesn’t know what to say
or how to respond. But instead of disengaging, it’s better
to be honest, tell your partner that you don’t know what
to say, you’re confused or upset or just feeling a lot of emotions, and you need to take a break. It’s a lot easier to
try again once the emotions have settled down, and it’s a
lot easier for your partner to know that you aren’t shutting
her or him out.
