EXPERIMENTAL METHODS
The IV can be controlled/ manipulated. Directly by the researcher using
standardised procedures and settings, e.g Bandura ­ the transmission of
aggression
Able to control the
potential confounding LABORATORY EXPERIMENT
variables Cannot be replicated to
real situations
Controlled and standardised = lacks generalisablity
procedures are easier to replicate
= RELIABILITY can be assessed Ps may behave differently
= demand characteristics and
research effects the results
These are conducted in the natural environment of ps often involving with
some degree of control
Lack of control and
Ps less likely affected standardisation over research
by researcher effects FIELD EXPERIMENT settings
than in a lab exp = makes replication difficult
High in eco validity, No demand Practically difficult and unethical to
behaviour taking place in characteristics as gather data unnoticeably
a non artificial ps do not know
environment they are being
observed
ADVANTAGES DISADVANTAGES
These may take place in labs or in natural settings but the IV naturally
occurs, e.g the conditions in Baron - Cohen = autism/ aspergers syndrome
condition
More eco valid QUASI/ NATURAL EXPERIMENT
= natural results
Ps variables may confound
Can be combined with results, e.g personal variables
laboratory experiments or
field experiments, based upon Practically difficult to find
the investigation natural occurring variables,
e.g ps who have brain surgery
