Research methods in psychology

Research methods in psychology is about how research methods can be utilized in psychological related research.

Overview

Psychology is a science. Psychological research involves a process of systematic investigation to enhance knowledge and understanding of human behaviour and experience (Willig, 2019).

A useful distinction is made between research which is:

• quantitative (using numerical data) and
• qualitative (using non-numerical data) research.

Arguably, the approaches represent two sides of the same coin. Or, as Karl Marx wrote:

“ Merely quantitative differences, beyond a certain point, pass into qualitative changes.
- Karl Marx “Capital: An abridged edition”, 1999, p. 322, OUP Oxford ”

Though predating the term "qualitative research", early pioneers such as Freud, Jung, and Piaget utilised such methods in their early work (e.g., case studies), and by doing so provided the foundation for modern psychology (del Rio Carral & Tseliou, 2019).

Nevertheless, since the first experimental psychology laboratory was established in 1879 by Wundt, psychological research become highly quantitative during the 20th century. During the 21st century, the methods and foci of psychological research have expanded and diversified (Nelson, 2015).

Each research method has strengths and weaknesses, so the selection of which method(s) to use should depend on the aims and nature of the research question.
