Q

What is a laboratory experiment?

A

An experiment set in a lab where the researcher has a high level of control of all the variables, in a control environment using standardised procedures. The IV is manipulates and the DV is measured.

Q

Pros of a laboratory experiment

A

researches can be confident in establishing a cause and effect relationship
high internal validity (DV is due to change in IV)
Easily replicated due to standarised procedures.

Q

Cons of Laboratory experiment

A

Lacks ecological validity a type of external validity
lab studies cannot be applied to the real world and tasks conducted in the lab dont reflect real life situations lacks mundane realism
demand characteristics.

Q

Cons of field experiments

A
  • possible extraneous variables that could be influencing the DV
  • cannot randomly assign participants to conditions to separate condition the change in DV may be due to participant variables reducing internal validity

What are natural experiments?

A

The IV would have occurred naturally without the researchers manipulation

Q

Pros of natural experiments:

A

allow research in areas that could not happen in a controlled experimentation due to ethical or cost reasons
high external validity
free from demand characteristics.

Q

Cons of natural experiments:

A

The events have already occurred regardless of the researcher hey have no influence therefore extraneous variables cannot be control
researches cannot claim they have a cause and effect relationship
The events are often rare and cant be replicated to test for their reliability.

Q

What are Quasi experiments

A

Participants cannot be randomly assigned because the Iv is an innate characteristic of the participants

Q

Pros of Quasi experiments

A

they are the only way to ecperimentally study factors that are prexisting characteristics of participants

Q

Cons of Quasi experiments

A

There may be other factors related to the level of IV that cannot be controlled (confounding variables)

Q

Informed consent

A

participants should be aware of the aims, purpose and consequences of taking part of the research and provide their informed consent before the study.

Q

Right to withdraw

A

before taking part in the research participants should be told they have the ability to end heir participation in the study at any stage (destroying any personal data collected on them)

Q

Protection from harm

A

researcher is responsible for designing research that doesn’t risk the psychological well being, physical health, personal values and dignity of the participants.

16
Q

Confidentiality

A

personal records should be kept securely and when it comes to publishing records keeping away personally identifiable information

17
Q

Debriefing

A

conversation that tells the participants the reasons for the research, outcomes and existence of any groups. Also can check for any harm cause by taking part and offer assistance.

18
Q

Dealing with ethical issues

A

revealing the true aims of a study when asking for informed consent can lead to demand characteristics, researchers can use an alternative informed consent

19
Q

Ethics: alternative informed consent
prior general consent

A

prior general consent: participants agree to long list of potential features that could happen in an experiment not knowing which part will be included in the study

20
Q

Ethics: retroactive consent

A

the researcher asks for consent after the participant has taken part in the study if the participant does not agree to take part their data is destroyed.

21
Q

Presumptive consent: ethics

A

the researcher asks a group similar to the sample if they would agree to take part in the research if he group agrees he researcher assumes the participants will consent too

22
Q

cost benefit analysis

A

if research requires deception or risks harm to participants this occurs assessing the potential harm of the participants and comparing this to the potential benefits of the research to society today

23
Q

reliability

A

measure of consistency (how consistency results are)

24
Q

external relability

A

measure we use is repeated another time if the results are the same or another the researcher gets it the second time (consistent with first results) do you get the same results when you use the same method at a different time ?

25
Q

internal validity

A

how consistent the different parts of measure we use, is the test consistent within itself

26
Q

experimental design : independent groups
advantages and disadvantages

A

no order effect
individual differences :(
participants may be allocated to conditions randomly

27
Q

repeated measures pros and cons

A

order effect :(
no individual differences :)
each participants undergo’s all conditionns of the experiment

28
Q

matched paris

A
29
Q

assessment on reliability

A

rest - retest = participants take test twice to see if if scores are reliable
use a correlation
inter observer - pilot the study

30
Q

improving internal validity

A

operationalise variables very carefully
run a pilot study to make sure iv is affecting dv
lack of confounding variables

31
Q

types of external validity

A

ecological - study relevat to real life
temporal - how relevant time time period is in affecting the findings

32
Q

face validity

A

whether it looks like what it should measure

33
Q

pilot studies

A

They are practice small scale studies done prior to the full study to test the methodology in order to remove any possible problems or sources of bias
They are essentially a ‘dry run’

34
Q

concurrent validity

A

is a type of evidence that can be gathered to defend the use of a test for predicting other outcomes

35
Q

pilot studies advantages

A

helpful in identifying potential issues early, which can then be rectified before committing to the length and expense of a full investigation.

36
Q

what are confederates?

A
37
Q

What is an observation

A

The researcher watches and records spontaneous behavior of participants without manipulating the levels of IV

38
Q

controlled observation

A

aspects of the environment are controlled in attempt to give all participants the sam eexperience
