Laboratory experiment- defined by the high level of control the researcher has over all the variables in the study
in a Laboratory study the experimenter will control environmental factors such as noise and temperature as well as the experience each participant has by using standarised procedures
Strengths of Laboratory experiment:
Confidence is establisting a cause and effect relationship
high internal validity
Lab studies easily replicated by using standardised procedure
Weaknesses of using laboratory experiments:
lack of ecological validity
lacks mundane realism
participants may alter behaviour due to demand characteristics
Laboratory experiments
Experimenter has full control over what happens in the experiment, environmental factors and instructions are highly controlled, only one factor (independent variable) changes between conditions
