Testing and Building Theories
Falsifiability is a game-changer in scientific thinking - basically, any worthwhile theory must be testable and potentially provable wrong. This separates real science from unfalsifiable ideas like Freud's unconscious mind, which you simply can't observe or test properly.
Theory construction follows a logical pattern: observe something interesting, build a theory to explain it, then create testable predictions. The hypothetico-deductive model takes this further - you generate hypotheses from your theory, test them with empirical data, then refine your theory based on what you discover.
Psychology's scientific status gets complicated when we consider paradigms - the shared assumptions and methods within a field. Unlike established sciences, psychology lacks one agreed-upon paradigm, with biological, cognitive, and other approaches often conflicting.
Paradigm shifts happen when new research completely challenges existing beliefs. Psychology has seen major shifts from psychoanalysis to behaviourism, then to cognitive psychology, showing how scientific thinking evolves.
Remember: Maguire's brain imaging study is falsifiable (you can test it), but Freud's theories about the unconscious aren't.
