Research Method Key Vocab AO1 Flashcards
Aim
States intent of study in general terms
Hypothesis
Prediction of investigation outcome that references independent and dependent variables
Independent Variable
Characteristics manipulated or changed by researcher
Dependent Variable
Variable measured in experiment
Null Hypothesis
No difference or no relationship between variables
Eg) predicting no effect
Operational Variable
Measurable variables
Extraneous Variable
All variables that are not the IV but may effect the DV
Confounding Variable
Not the IV but does vary systematically with it.
Cause change in DV
(controlling EV)
Standardisation
All aspects of environment standardised as much as possible
(controlling EV)
Single Blind
Participant has no knowledge of what to expect for outcome
(controlling EV)
Double Blind
Participant has no knowledge of study and experimenter doesn’t know the aim
(controlling EV)
Random Allocation
Randomly allocate participant to each condition of IV
Situational Variables
Factors in environment that can unintentionally effect DV
Eg) noise, temp, lighting etc
Participant Variable
Individual characteristics of each participant that may impact how they respond to experiment
Demand Characteristics
Participants finding out the aim of experiment and changing behaviour
Investigator/Experimenter Variable
Experimenter conveys to participant how they should behave
Eg) smile and nod at participant when they do what they’re expected
Order Effects
Any effect that comes from participants doing both conditions of experiment
Eg) boredom, improved performance due to practice
Social Desirability
When participant wants to come across well to researchers
Eg) not complete questionnaire truthfully about prejudice to seem more moral
Placebo Effect
Brain tricking people into thinking they feel a certain way due to drug working, as they expect to feel this way. Mind over matter
Participant Observation
researcher joins in becoming part of group they are studying
Non Participant Observation
Researcher remains detacthed from observation
Structured Observation
Clearly defined way of measuring behaviour
Unstructured Observation
No set categories to look for
Observer Bias
Only see what you want to see based on prior knowledge or subjective feelings
Naturalistic Observation
takes place in setting where behaviour naturally occurs. Nothing manipulated
Ecological Validity
population Validity
Historical Validity
Measures how generalisable experiment findings are to;
real world
other people
other times
Controlled Observation
Standardised procedure
Covert Observation
Participant unaware that they are being watched
Overt Observation
Aware of being watched
Event Sampling
Record observation when target event behaviour occurs
Time Sampling
recording all behaviours during specified time period
Counterbalancing
Balances out order effects.
Half do condition 1 other half do condition 2 first.
Standardised Instructions
Same instructions for all participants
Ensuring Anonymity
Participants know results anonymous
Vicarious reinforcement
indirect learning through others experience of reward and punishment
Modelling
Someone influential on individual
Limitation
Observe and copy behaviour
identification
Wanting to be like role model depending on extent of similarities
Retention
Memory of behaviour must be formed to be performed by observer
Motivation
Behaviour likely to be imitated by observer if perceived reward outweighs perceived cost
Attention
Pivotal in whether behaviour has influence on others imitation
reproduction
recreation of behaviour
