5. June 2014
Psychologists use a range of methods to
collect their data including experiments and
observations. Behaviourists believe that the
subject matter of psychology should be
observable behaviour and experiments can
sometimes include the use of observational
techniques. The presence of others can be
studied experimentally by measuring what
participants are doing rather than what they
are thinking.
You must choose one of the options:
• The effect of presence of others on musical performance.
• The effect of presence of others on sport performance.
• The effect of the presence of others on mathematical skill.
• The effect of the presence of others on acts of kindness.
• The effect of the presence of others on acts of aggressive
behaviour.
• The effect of the presence of others on acts of food choices.
• The effect of the presence of others on face recognition.
• You must use an independent measure design and plan to collect
data which measures observable behaviour. It must be a practical
project that could be conducted.

Are these significant?
Don’t forget, if they are significant, you reject your null hypothesis and accept the
alternative one; if they aren’t, you retain the null and reject the alternative.
