Definition
not really, we can only hold 7+ or- 2 facts at a time in our short term memory and we commonly make mistakes in our logical reasoning
Term
According to Gilovich, what are the common violations of logical reasoning?
Definition
-making something out of nothing -see what we expect to see -too much from too little -believe what we are told -imagine agreement of others
Term
making something out of nothing
Definition
humans have a difficult time detecting randomness. people tend to look for causal relationships for random events
Term
Wolford Study
Definition
a light is lit 80% on the right and 20% on the left. People try to guess the pattern and get 68% correct. Rats press right every time and get 80% correct.
Term
in the Wolford study, what is the most accurate way of prediction: probability or maximizing
Definition
maximizing

Definition
judgement by representativeness, inappropriate application of prototypes: real random sequences have too many subcomponents that look consistent for human ovservers to consider them random
Term
misperceptions of regression to the mean
Definition
2 variables related, but not perfectly, an extreme value at one end is more likely to be followed by a less extreme value
Term
Schafner experiment with reward vs. punishment
Definition
High school student plays the role of teacher. They can either reprimand, reward, or make no comment to a hypothetical student who arrives randomly early, on time or late. Students rewarded early arrival and reprimanded late arrival. 70% believed punishment was more effective
Term
In Schafner's experiment why did the students believe punishment was more effective?
Definition
because of the random arrival times, if a student is early one day, he is more likely to be on time or late the next day. The reward given seems not to work. If a student arrives late one day, he is more likely to arrive early or on time the next day. The punishment given seems to have worked.
Term
Seeing what we expect to see
Definition
learning memory and belief impact evaluation of new data. This is generally a good thing however it can be bad if it doesnt allow an objective viewpoint
Term
Lord's Mixed Evidence Experiment
Definition
Two groups of people: in favor and against the death penalty. Two studies presented to each observer, one that supported the view of the supporter and one that contradicted the view. half of the group against the penalty was given study one in support and study two in contradiction and the other half was given study one in contradiction and study two in favor. The same was done with the group in favor of the death penalty.
Term
Results of Mixed evidence experiment
Definition
the participants believed the study that supported their view was a well conducted peice of research and the study that refuted their view had numerous flaws no matter which study they recieved. Subjects did not view support as more favorable as it was or ignore findings that refuted their position but they spent more time considering the refuting evidence and produced mostly valid criticisms of the study thus leaving the supporting study unchallenged
Term
believing what we want to believe
Definition
we believe a large number of things about ourselves that do not stand up to objective analysis

Term
self rating of college professors
Definition
94% of college professors rate themselves as better at their jobs than their average colleague
Term
Tendency to ignore the priors
Definition
Bayes rule takes into accout prior statistics that are relavant. Because there is such a large number of healthy women taking the test, Out of 1000 people, 107 will test positive but only 8 of those women actually have breast cancer. This shows that we look for confirmatory evidence assuming the disease.
Term

Definition
we act rationally and reasonably most of the time but the processes by which we achieve this are not logical. We use other kinds of processes to simulate rationality
Term
neural networks and searching
Definition
define a good solution, note all factors that impact, define a cost function, and search for the minimum cost

fight, flight, feeding, and f**king
Term
when emotions occur in animals with consciousness..
Definition
emotions are experienced consciously, generated by unconscious processes, once aroused the feelings are conscious, post hoc analysis
Term
why can emotion be studied using animal models?
Definition
because animal and human brains are more comparable here than anywhere else
Term
emotions happen to us
Definition
passively, though we can try to manipulate them
Term
what did the lesion/ablation approach show about emotion?
Definition
decorticate animals showed normal emotion, autonomic arousal (pupil dilation, blood pressure increases, piloerection etc.) although somewhat abnormal. This implies that emotion is located in the limbic region of the brain
Term

emotion from integration circuit
Definition
stimulus - thalamus - cortex - cingulate - hippocampus - hypothalamus - thalamus
Term
Ekman's list of emotions
Definition
used facial expressions to decide this list because they are universal indicators of emotion: fear, sadness, happiness, anger, disgust, surprise
Term
for each emotion, name a psychological problem created from too much of that emotion
Definition
fear:phobias, sadness:depression, happiness:mania, anger:agression, disgust:OCD
Term
Why did LeDoux choose fear as a way to study emotions individually?
Definition
because fear is pervasive and diverse in humans, prominent and diverse in psychopathology, and expressed similarly in humans and animals
Term
what are the natural reactions to fear in humans and animals?
Definition
withdrawl, immobility, defense aggression, submission
Term
what happens in the presence of danger to an animal?
Definition
the animal is startled, it orients, then if far it will flee, if close it will freeze, if unsuccessful it will vocalize and attack
Term
fear conditioning
Definition
standard classical conditioning, learning to pair a previously objective stimulus to a painful outcome even when that stimulus does not itself cause pain
Term
fear conditioning rats to reveal where fear is in the brain
Definition
associated loud noises to fear, damage to the auditory cortex did not extinguish the condtioning. Anotomical tracers revealed projections to four areas, once amygdala was destroyed there was no fear conditioning
Term
what does the amygdala do?
Definition
it activates body responses to fear. Because of its position, the amygdala allows the fear to bypass the neocortex which makes the process faster.
Term

Definition
a brain process (physiological reaction to a stimulus) a psychological reacton to a perception, system of drives, actions, fulfillment
Term
taxonomy: primary emotion
Definition
hard-wired through limbic system (stimulus activates the system), physiological response

prefrontal cortex bilaterally, ventral and inner surfaces affected, vertromedial (known to be involved in decision making)
Term
elliot
Definition
brain tumor patient, ventromedial prefrontal damage. After surgery he was unable to make a good decision even though his IQ, language comprehension, face matching skills, perceptual skill, etc. were normal.
Term
what was causing Elliot's inability to make decisions?
Definition
he was uneffected by emotions, elliot could generate the possible solutions and evaluate outcomes, but still said he didnt know what to do (somatic marker hypothesis)
Term
somatic marker hypothesis
Definition
decisions involve a body-based marker that is the result of a secondary emotion, there is an associative connection to a previous experience, before the cost-benefit analysis we go with our feeling
Term
