25
ponzo illusion
linear perspective suggests that objects are further away; perceptual system makes me size retinal image seem larger
26
the Ames room illusion
all depth cues suggest these people are the same distance from the observer; they are not
27
figure/ground distinction
the distinction between that which stands out and that which is background
28
acquisition
the process of attending to a stimulus and encoding into memory
29
retention
preservation of stored material over an interval
30
retrieval
process of getting information back for use
31
decay
with time it is like the memory trace rusts
32
displaced
new items can enter short term memory and knock others out
33
primacy effect
earlier information has stronger influence than later info
34
negativity bias
negative information has stronger influence than positive information. especially in the domaine of sociability and morality

halo effect
Assumption that someone with known positive qualities also possess additional undisclosed positive/negative qualities

attribution theory
an explanation of how people develop a causal understanding of human behaviour
39
actor-observer effect
when we look for causes of behaviour it matters if we are the actor or the observer
40
fundamental attribution error
the tendency to consider behaviour to reflect underlying and immutable properties of people
41
false consensus
tendency for people to believe that their own behaviour is widely shared and that their own views are consensual
42
self-serving bias
tendency to attribute one's success to dispositional characteristics and one's failures to situational factors
43
representativeness heuristic
classifying something as belonging to a certain category to extent it is similar to typical case
44
availability heuristic
estimate likelihood of event by ease with which instances of that event come to mind
45
anchoring and adjustment heuristic
estimates are made by starting with an initial value (anchor) that is adjusted to reach an answer
46
nature of attitudes
relatively enduring sets of beliefs, feelings and intention towards an object, person event or symbol
47
dissonance
unpleasant state; tension arises when perceived discrepancy between: - attitudes and beliefs - behaviour and self-image - one attitude and another
48
mere exposure effect
attraction to stimuli that are familiar to us
49
social influence
how other people influence our behaviour
50
compliance
change of behaviour in response to a direct request
51
obedience
change of behaviour in response to a direct oder from a police officer, parent, teacher or school official
52

55
commitment
