The Early Foundations of Psychology

Psychology officially became the scientific study of the mind, behaviour and experience, but this didn't happen overnight. Key philosophers and scientists laid the groundwork centuries before psychology became its own subject.

René Descartes (1596-1650) came up with a revolutionary idea called Cartesian dualism - basically, he argued that your mind and body are completely separate things. His famous phrase "I think, therefore I am" suggests that thinking proves your existence, which was pretty mind-blowing for the 1600s.

John Locke (1632-1704) had a different take entirely. He proposed empiricism, arguing that you're born as a blank slate and everything you know comes through your senses and experiences. No inherited knowledge or instincts - just pure learning through life.

Charles Darwin (1809-1882) revolutionised how we think about behaviour with his evolutionary theory. He suggested that both human and animal behaviours evolved over time, with stronger, more adaptive traits surviving through "survival of the fittest."

Key Point: These early thinkers set up the fundamental debates in psychology - nature vs nurture, mind vs body, and how we acquire knowledge.

The breakthrough came when Wilhelm Wundt opened the first experimental psychology lab in Germany in 1879, making psychology a distinctive discipline. Meanwhile, Sigmund Freud was developing his ideas about the unconscious mind and psychoanalysis therapy in the 1900s, emphasising how hidden mental processes influence behaviour.

Modern Approaches Take Shape

Psychology really took off in the 20th century as different psychological approaches emerged, each offering unique perspectives on human behaviour. You'll encounter all of these in your A-level studies, so getting familiar with their origins is crucial.

John Watson established the behaviourist approach in 1913, later joined by B.F. Skinner. They focused purely on observable behaviour, rejecting the study of mental processes as unscientific. Around the same time, Carl Rogers and Abraham Maslow developed the humanistic approach in the 1950s, emphasising self-determination and free will - basically the opposite of behaviourism's mechanistic view.

The cognitive approach emerged in the 1950s, reintroducing mental processes to psychology thanks to computer technology providing new metaphors for understanding the mind. Albert Bandura bridged cognitive and behavioural thinking in the 1960s with his social learning theory, showing how cognitive factors influence learning.

Remember: Each approach offers a different lens for understanding behaviour - none is completely right or wrong, they just focus on different aspects.

The biological approach became dominant in the 1980s due to technological advances that let scientists actually see inside the brain. Finally, cognitive neuroscience emerged around the 21st century, combining cognitive and biological approaches to investigate how brain structures influence mental states - essentially bringing psychology full circle back to modern versions of old questions about mind and body.
