psychology
the scientific study of behaviour and the mental process
science
uses systematic methods to observe human behaviour and draw conclusions
behaviour
everything we do that can be observed directly
mental process
thoughts, feelings, and motives that each of us experience but cannot be directly observed
scientific psychologists
systematically study the mind, brain, and behaviour
8 levels of analysis
macro
meso
micro
molecular
molar
social psychology
sociology
neuro
ontology
the study of what is
the search for what is real
materialism
Marx
only material things exist
idealism
hegel
some of reality exists separately from the sensible world
epistemology
the study of knowledge and how individuals gain knowledge
aimed to identify the basic fundamental elements of psychological experience
structuralism
aimed to understand the adaptive purposes of psychological characteristics
functionalism
founded by William James
psychoanalysis (sigmund frued)
psychodynamic theory
focuses on the internal psychological process of which we are unaware
behaviourism
focuses on uncovering the general laws of learning by looking outside of the organism to rewards, punishments, and behaviour present in our environment

classical conditioning:
UCS
unconditioned stimli
classical conditioning:
UCR
unconditioned response
classical conditioning:
NS
neutral stimulus
classical conditioning:
CS
conditioned stimuli
classical conditioning:
CR
conditioned response
steps of classical conditioning
- neutral stimulus
- pair NS with UCS which causes an UCR
- eventually NS turns into a CS eliciting a CR
law of effects thorndike 1898
if a response in a presence of a stimulus, is followed by a satisfying state of affairs, the bond between the stimulus and response will be strengthened
operant conditioning terminology:
outcomes or consequences that strengthens the probability of reinforcement
reinforcement
operant conditioning terminology:
pleasant stimulus is given to strengthen the probability of a resins
pos reinforcement
