Ethical Issues Re: you as students

• Informed consent (prior general consent)• Deception (you will be deceived at times)• Debriefing (always debriefed as will link to learning)• Right to withdraw (you do not have the right to

withdraw as is course requirement)• Confidentiality (I cannot promise you confidentiality

so you have the right to lie)• Protection (I will DEFINITELY protect you from physical

harm or emotional harm – embarrassment)

My aunt’s bathroom scales

• Reliability = consistency, can it be replicated?

e.g. the scales say every day that my 15 stone aunt is 8 stone. FULLY RELIABLE.

• Validity = accurate, does it truly test what is being studied?

e.g. she is actually 15 stone. COMPLETELY INVALID.

SamplingL/O: To be able to differentiate between RANDOM, OPPORTUNITY and VOLUNTEER sampling methods.

Starter:

You are conducting a research project where you hope to prove (hypothesise) that there is a difference in intelligence between men and women.

Who do you need to take part? How will you recruit?

Participants = the people who take part in research.

Population = the group of people your participants come from.

Sample = the selection of participants, from the population, who take part in your research.

• Typical• Representative• Cross-section of people

= can generalise findings to general population.

IF NOT: Sample bias *a criticism you can often use in evaluating studies so check the sampling method*

SAMPLINGParticipant sampling is important in psychological

research.

Which question from your homework could have been answered using ‘SAMPLE BIAS’?

Random: every one in the population has equal chance of taking part. e.g. names from a hat or random selector computer programs.

Opportunity: use anyone you can get hold of. e.g. waiting for people to pass by you.

Volunteer: requesting for people to take part. e.g. poster, advert, maybe a small payment.

L/O: To be able to differentiate between RANDOM, OPPORTUNITY and VOLUNTEER sampling methods.

RANDOM, OPPORTUNITY or VOLUNTEER sampling?

1. You wait by the sixth form centre entrance and approach people as they enter to take part.

2. You put an advert on the sixth form notice board asking people to contact you if they would take part.

Create and write a situation for the remaining one.

Application of Sampling

• Read an applied sampling question carefully.

• Last year:Name the sampling technique used in this experiment. Evaluate the choice of this sampling technique in this experiment.(1 mark + 3 marks).

Ethics and Ethical Issues

• The British Psychological Society (BPS) are the professional body for trained psychologists.

• Read the ethical principles set out by the BPS(page 19, textbook).

Discuss and try to unpick it. What is it saying?

L/O: to be aware of and understand the implications of ethics in psychological research.

EXAM TIP: Examiners look for evidence of your

understanding of ethical issues.These should be learned and can be used to

evaluate (criticise) lots of studies!

Deception in particular.

1. Read Milgram (1963) – page 190-191

2. Identify the ethical issues in Milgram’s research.

Take notes under the 6 headings:• Informed consent• Deception• Debriefing• Right to withdraw• Confidentiality• Protection

Pg.193 – how do your notes compare?

L/O: to be aware of and understand the implications of ethics in psychological research.

AO1: knowledge.AO2: application

of knowledge.

How to control bias?

• Single-blind control: to keep participants in the dark about the real aim of the research.

• Double-blind control: both participants and researcher are kept unaware of the aims.

Demand characteristics – when a participant alters their

behaviour.

Investigator effects – when a researcher unconsciously influences participants’

behaviour.

Any ethical issues?

Example exam questions: ethics

1) How could a psychologist maintain confidentiality when reporting a case study? (2 marks)

2) Outline two ethical issues that arise in research involving children. (2+2 marks).
