What is experimental psychology
The phrase “experimental psychology” refers to
a specific methodological approach to the study of psychology
as well as to several specific areas of research within psychology which predominantly use experimental methods
Experimental psychology involves the collection of what
reliable and quantifiable behavioural data
Often empirical tests are conducted under what
Controlled conditions
Specific areas of study within psychology which predominantly use experimental methods include what
sensation, perception, physiological and comparative psychology, Emotion and motivation, Conditioning and learning, Memory cognition
What are the basic elements
Control Group
Random Allocation
Pre- /Post- testing
Hypothesis testing
The Scientific Methods six basic elements
Observation
Defining a problem
Proposing a hypothesis (an educated guess that can be tested)
Gathering evidence/testing the hypothesis
Publishing results
Building a theory
Empirical investigation in psychology may be what
experimental, quantitative observational or qualitative
All investigation designs and methods of assessing psychological responses have what
Advantages and Disadvantages
All investigation designs and methods of assessing psychological responses have what
Ethical dimensions
What are the 3 investigative designs
experimental, quantitative observational, and qualitative
What are the 3 methods of assessing psychological responses
Quantitative measures
Subjective quantitative measures
Qualitative assessment data
What is the 4 levels of explanation used in psychology
The Biological level
The basic processes level
The personal level
The sociocultural level
What is the Biological level
The biological level of explanation focuses on the biological and chemical processes underlying behaviour.
What is the basic processes level
The basic processes level of explanation focuses on the psychological processes that are universal
What is the person level
The person level of explanation focuses on individual differences in behaviour.
What is the sociocultural level
The sociocultural level of explanation focuses on the influence that other people exert on behaviour by studying behaviour in social and cultural contexts.
What groups are involved in the experimental method
Experimental group
Control group
What is random allocation
Random allocation means that all participants who have been selected for an experimental are just as likely to be in one group as the other
Differences between Experimental Designs and Quantitative Observational Designs
One of the main differences is that the ‘treatment’ pre-exists in the two groups being compared whereas in an experiment the researcher manipulates the research groups.
Advantages of Quantitative observational design
Quantitative Observational designs allow variables to be investigated that would be unethical, impossible or too costly under an experimental design.
Disadvantages of Quantitative observational design
Cannot infer such a strong cause and effect relationship because there is a greater chance of other variables affecting the results. This is due to the lack of random assignment to groups.
What are focus groups
Focus groups refer to a group interview technique that obtains data through discussion between research participants in a group setting.
What advantages of focus groups
May be more convenient that one-on-one interviews
Rich data can be collected
Easy to organise and inexpensive to conduct.
Useful for collecting information from people who are unable to read or write
What are the disadvantages of focus groups
People may not feel comfortable expressing opinions in front of others
A few people may dominate the discussion
Interviewer bias may contaminate the results
Cannot establish causation
The data from a focus group should not be interpreted to be representative of the entire population
