Like any other science, psychology is concerned with theories and data. Psychologists use a wide range of research methods and techniques that allow them to gather and make sense of the data that they produce. The methods that psychologists use to research and analyse the experience and behaviours of individuals or groups are called psychological research methods. This essay will be investigating and analysing three research methods to include; experimental, observational and surveys, also, reflecting on their strengths and weaknesses of each in addition to their usefulness in the psychology field.

The first method to be discussed and analysed are experimental methods. There is a variety of experimental methods including; laboratory, field and natural experiments. These methods are the most scientific method due to them being highly objective and systematic. In addition, this method is regarded as the most powerful research method used in psychology because of the potential to investigate the causes of events and therefore, identifying the cause and effect relationship. When carrying out an experiment the researcher intervenes directly in the situation being investigated. The researcher manipulates an independent variable (IV) in order to investigate whether there is a change in the dependent variable (DV). Any other variables that could have an …show more content…

In this essay, the author

  • Explains that psychology is concerned with theories and data. psychologists use a wide range of research methods and techniques to gather and make sense of the data that they produce.
  • Explains that experimental methods are the most scientific method due to being highly objective and systematic. the researcher manipulates an independent variable to investigate whether there is a change in the dependent variable.
  • Explains the advantages and disadvantages of laboratory experiments, such as their lack of ecological validity and mundane realism.
  • Explains the field experiment, which is done in the everyday environment of the participants. the researcher controls the iv, but cannot control other extraneous variables.
  • Explains that field experiments can conclude cause and effect, for the same reasons as a laboratory experiment. ethical issues arise when participants are not aware of being observed as part of the study.
  • Explains that the quasi-experiment is conducted in the everyday life environment of the participants. the experimenter does not have control over the iv as it occurs naturally in real life.
  • Explains that the natural experiment has high levels of ecological validity due to its natural setting and lack of direct intervention. this type of experiment can be used when it would be ethically unacceptable to manipulate the iv.
  • Explains observational methods are of a non-experimental design where the absence of the iv does not allow any cause and effect relationship.
  • Explains that naturalistic observation has high levels of ecological validity due to observing the behaviour in its own setting.
  • Explains surveys are used in psychology research to collect self-report data from study participants. surveys investigate the characteristics, behaviours, or opinions of a group of people.
  • Explains that surveys can be administered as structured interviews or as self-report measures such as questionnaires. written surveys are susceptible to nonresponse bias and social desirability bias.
  • Explains that psychological research methods are important because research helps psychologists understand what goes on in the human mind and what causes individuals to act the way they act.

Observational methods are of a non-experimental design where the absence of the IV does not allow any cause and effect relationship. There are different types of observations to include; participant, nonparticipant, structured, non-structured and naturalistic. This method includes an observation of the respondent by the researcher in the respondent’s natural social settings. The researcher has no influence over the behaviour of the respondent. Observations are commonly used to study aspects of development, including physical, social, emotional and intellectual
