4. Theory Construction
About this Lecture
In this lecture, we think about theory construction, focusing in particular on: (i) paradigms as a method of moving from idea generation to testing a theory and informing its construction; (ii) the objective testing and statistical analyses required to confirm a hypothesis; (iii) establishing an actual theory as the final process in theory construction; (iv) paradigm shifts as key points in the history of science which have uprooted existing ideas and made way for new theories; (v) an example of a paradigm shift in psychology, when the multi-store model was uprooted in favour of the levels of processing approach.
In this course, Dr Ashok Jansari (Goldsmiths, University of London) explores how researchers report good (or sometimes not good) science. In the first lecture, we think about the three main forms of validity: face, concurrent, and ecological. In the second lecture, we think about the three main forms of reliability: test-retest, inter-rater, and internal. In the third lecture, we think about features of science and how the empirical method can promote good scientific practice. Next, we think about theory construction and the process that a good researcher will follow to work from their initial idea towards their finished theory. In the fifth and final lecture, we think about scientific reporting and the five key sections of a report which adheres to the American Psychological Association (APA) standard.
Dr Ashok Jansari is a senior lecturer in the Department of Psychology at Goldsmiths, University of London.
