25
Relearning
"method of savings" -how much more quickly we reacquire something learned before Measuring memory
26
Tip of the tongue phenomenon
its in there somewhere -NOT KNOWN -RETRIEVAL FAILURE long-term memory
27
Encoding specificity
memory is enhanced when conditions present during retrieval match those present during encoding -context-dependent memory -State-dependent memory
28
Context-dependent memory
easier to remember things when context of retrieval matches context of learning Ex: in the same learning environment) Encoding specificity
29
State-dependent memory
better memory when retrieval internal state matches learning one -Mood dependent learning -Sad= easier to remember unpleasant events -Happy=Easier to remember pleasant events Encoding specificity
30
Single engram
1920 physical trace memory in the brain rat in maze: more brain tissue removed= worse memory -Location of damage didn't seem to matter
31
Engram is located where?
1949 located in assemblies of neurons -Neurons that fire together, wire together
32
Lont term potentiation (LTP)
Strengthening of connections among neurons due to simultaneous stimulation -Neurons in the hippocampus, amygdala, and cortex show long-term enhanced response following certain stimulation (Ex learning episode, such as pavlovian fear conditioning) -Glutamate plays a role
33
Brain Areas involved in memory
-Frontal lobe -Cerebral cortex -Prefrontal cortex -Hippocampus Cerebellum
34
Types of amnesia
-Retrograde -Anterograde -Infantile
35
Retrograde Amnesia
-Loss of past memories before onset of amnesia
36
Hollywood amnesia
-loss of all past memories -very rare
37
Anterograde amnesia
-Inability to form new memories since onset of amnesia -Far more common
38
Infantile Amnesia
people typically don't not have memories from before they were 4 years old Because of: -Hippocampal development -completed around age 2 -Lack of sense of self -15 months to 2 years
39
Fetal memory
Habituation to novel stimuli begins at 32 weeks in utero
40
Infant implicit memory
Respond to operant conditioning at 2 months -2 months a few days -6 months a few weeks
41
Memory development
-Memory span increases -biological maturation imporved conceptual understanding -Better ability to find meaning and chunk enhanced meta effort is needed -Assess when effort is needed -Over confidence becomes accurate assessment
42
Misinformation effect
the distortion of a memory by misleading post-event information Ex: how fast was the car going smashed (remembered way faster) vs Contacted "another car"
43
Inplanting memories is more likely:
-for PLAUSIBLE events -for distant PAST events
44
The Repression Controversy
Repression -forgetting threatening or upsetting information individuals are more likely to struggle with forgetting traumatic events NOT testable
45
Eyewitness
Not reliable -Cross race identification -Question wording -crashed versus hit -Misleading information
46
Childrens testimony
More suggestible -They are young -When the interviewer has a want for what the kid says -When other children's memories for events are accessible
47
Manufacture of memory
-the capacity to retain and retrieve information -Recovering a memory is not playing a videotape -a reconstructive process
48
Flashbulb memories
-emotional memories that are so vivid we can recall them in great detail -they are no more accurate -we have much greater CONFIDENCE in their accuracy
49
Source amnesia
the inability to distinguish what you originally experienced from what you heard or were told later about an event
50
Cryptomnesia
Forgetting that "our" idea was actually someone else's
51
Confabulation
Confusion of an event that happened to someone else with one that happened to you -or A belief that you remembered something when it never actually happen
52
Confabulation is more likely when:
-You have though/heard about the imagined event many time -The image of the event contains a lot of details -The event is easy to imagine -You focus on the emotional reactions to the event rather than on what actually happened
53
Emotions
A motivated state marked by Physiological arousal, expressive behavior, and mental experience
54
Discrete emotions
Theory that humans experience a small number of separate emotions -Combine to create emotional experiences
55
Adaptive functions of emotions
Focus attention -Fear Avoid toxins -Disgust Motivate behaviour -Lust
56
7 basic emotions
-Happiness -Anger -Surprise -Disgust -Contempt -Sadness -Fear -experienced by all people in all cultures -Emerge in the first 9 months -innate motor programs
57
Secondary emotions
-Complex emotions that combine primary emotions -Guilt, embarrassment, regret
58
Physiology - emotions
-Physiological response to some emotions (anger-fear) are very different -Physiological response to other emotions is similar (fear-excitement) -Facial expressions can alter physiological and emotional state
59
Display rules
-Culturally derived guidelines controlling how and when to express emotions
60
James-Lange Theory of emotion
Experience of emotion is caused by somatic feedback
61
Canon-Bard theory of emotions
Thalamus simultaneously stimulate experience and physiological response
62
Two factor theory -theory of emotion
-Producing an emotion requires: -Undifferentiated state of arousal -Attempt to explain our arousal -Why am i aroused? -Label arousal with an emotion
63
Nonverbal expression
-Body language -Gestures -Proxemics
64
Nonverbal leakage
unconscious spillover of emotions into nonverbal behavior Ex: body language
65
Gestures
nonverbal expression -Illustrators -Manipulators -Emblems
66
Illustrators - Gestures
highlight and accentuate
67
Manipulators - Gestures
Touch, stroke, poke another body part
68
Emblems - Gestures
gestures conveying established meanings
69
Proxemics - personal space
-Intimate -0 to 50cm -Affectionate touch, intimate conversation, comforting -Personal -50 to 125 cm -Conversations with friends -Social -1.25 to 3 m (4-12ft) -conversations with strangers, business transaction -Public -beyond 12ft -listening to speeches, formal occasions
70
Positive psychology
-Emphasizes human strengths, such as resilience, coping, life satisfaction, love and happiness -up to 50% of happiness is genetically based
71
Happiness is correlated to:
-Longevity -Increased performance
72
Myths about what makes us happy
-The prime determinant of happiness is what happens to us -Money makes us happy -Happiness decline in old age -Happiness and negative emotions lie on opposite ends of the spectrum -people on the west coast are the happiest
73

74
Instinct theory
-Fixed action pattern -Inherited Characteristic, common to a species that automatically produces a particular behavior in response to a particular stimulus
75
Drive reduction theory
-Homeostasis -state of internal physiological equilibrium -Disruption to homeostasis produce drives to behave in a certain way Ex: thirst influences drinking -"pushes" organism into action
76
Extrinsic motivation
EXTERNAL performing and activity to obtain an external reward or avoid punishment
77
Intrinsic motivation
INTERNAL Performing an activity because you find it enjoyable or stimulating
78
Approach - approach
opposition between two attractive alternatives -Motivational conflict
79

83
Sexual response cycle
1. desire phase 2.Excitement phase 3.Plateau phase 4. Orgasm phase 5. Resolution phase
84
Desire phase - Sex
something prompts sexual interest
85
Excitement phase - sex
-blood flows to arteries in genital organs, nipples, and breast -sexual pleasure begins
86
Plateau phase - sex
sexual tension builds, ultimately leading to orgasm
87
Orgasm phase - sex
-sexual pleasure and physical changes peak -respiration, heart rate, and muscle tension build -Rhythmic muscle contractions and pleasure

a powerful longing for ones partner
92
Companionate love
a sense of deep friendship and fondness for ones partner
93
Initiating hunger
-Decrease in blood glucose levels are detected by liver sensors, which convert stored nutrients back into glucose -Drop-rise pattern may be a signal of "hunger" to the brain
94
Satiation (stopping eating)
-Stomach and intestinal distention -peptides sent into bloodstream as food arrive sin intestines from the stomach
95
Leptin
hormone in the fat cells that decrease appetite
96
Set point - eating
genetically programmed ratio of body fat to muscle mass that our bodies try to maintain -modifiable
97

May be involved in stimulating eating, but is not a hunger on center
98
Ventromedial hypothalamus (VMH)
may influence stopping eating, but is not a hunger off center
99
Phycological aspects of hunger
-positively reinforced by good taste and negatively reinforced by hunger reduction -Expectations that eating will be pleasurable and will reduce hunger stimulate eating -Beliefs, memories, and attitudes about food can also affect eating
