A new perspective on trends in psychology

The current paper aimed to analyze quantitatively the trends of four major schools of thought in scientific Psychology (neuroscience, cognitivism, behaviorism, psychoanalysis) and their intersections, covering the period from 1979 to 2020. We utilized a rigorous methodology across three distinct sources: Mainstream Psychology (MP), Highly Influential Journal (HIJ), and non-English papers (NEP). Our findings align with previous research in two aspects: psychoanalysis and behaviorism have significantly declined, cognitivism remains a prominent trend. However, we deviate from prior studies by recognizing that neuroscience may be considered the most influential trend and that trends exhibit less linearity than previously assumed. We also acknowledge the significance of NEP, which manifest an independent pattern as compared to the other sources and that may reveal what happens in the "periphery" of Psychology. It is noteworthy that NEP demonstrated a still lively contribution from psychoanalysis. Our study also highlights the insularity and lack of cross-fertilization among psychological subdisciplines, despite the widespread claims to the contrary. It eventually supports the inference that scientific Psychology is a non-paradigmatic or pre-paradigmatic discipline, pointing out the dominance of applied psychology and confuting the notion of overarching "grand theories".
