-how they are affected by an organisms physical state, mental state, and external environment
what is pseudo-psychology?
the phony or unscientific psychology
psychology vs. psychiatry
psychiatry: specialty in medical field, can prescribe medication for mental and behavioural problems
psychology: broader field with many specialities
hindsight bias?
tendency to believe after learning the outcome, “i knew all along”
overconfidence
the tendency to think we know more than we do
quick and confident thinking over correct answers
gambler’s fallacy
occurs when gamblers believe after losses a win is due soonall events are random and independent
waves of thought
introspection, gestalt psychology, psychoanalysis, behaviourism
theory
explains behaviours/events by offering ideas that organize observations
whats one thing you have to look out for when testing a theory?
falsifiability…..can it be proven wrong?
what is an experiment
research method that manipulates one or more factors to observe behaviourrandom assignment of participants
experimental method?
this is the only way to prove causal relationships cause = effect
experiments need two groups
experimental group: exposed to the independent variable
control group: not exposed to the independent variable
what are confounding variables?
variables that affect the results, harder to prove that the iv caused the results
ethnocentrism?
experimenter assumes behaviours that are typical in their cultures
all components of an experiment?
hypothesis, iv, dv, experimental/control groups, random sample/assignment, and placebo*
what is a case study
an in-depth study of an individual or group for long periods of time to collect data
done to hopefully reveal universal principles
naturalistic observation? strengths/weaknesses
non-experimental technique to observe behaviour without manipulating anything: real data, no hawthorne effect, cant react to researcher
survey method, strengths/weaknesses
a non-experimental technique
s: gathers large amounts of data fast/easily
w: does not provide causation
case study strengths/weaknesses
s: chronological data, full picture, different views
w: time consuming, does not provide causation, cannot always be generalized, expensive
directionality problem
cannot tell us which variable is the cause, which one is the effect
correlational coefficient
strength of the relationship, ranging from -1 to +1
types of correlation…
positive correlation (two up arrows), negative correlation (one up one down)
scatterplots?
a graph that reveals the correlation between two variables
if the correlational coefficient is 0 what does that mean?
no correlation between the variables
