Psychology definition:
Page 104
The scientific study of the human mind and its functions, especially functions affecting behaviour in a given context.
A01
Science definition:
Page 104
A means of acquiring knowledge through systematic and objective investigations. The aim is to understand, explain, predict, and sometimes influence behavior and mental processes (general laws).
A01
Introspection definition:
Page 104
Introspection in psychology is the process of examining and reflecting on one’s own thoughts, feelings, and mental experiences.
A01
The first systematic experimental attempt to study the mind by breaking up conscious awareness into basic structures of thoughts, images and sensations.
Who is Wundt, and what was his objective (aim)?
Page 104
Wilhelm Wundt opened the first psychology lab to study human consciousness,
The objective was to document and describe the nature of human consciousness known as introspection. Him and his team recorded their own conscious thoughts to break them down into basic elements, aiming to uncover and isolate the structure of consciousness— called structuralism.
A01
What was Wundt’s controlled methods/conditions for Introspection?
Page 104
A01 + A03
All introspections were recorded under strictly controlled conditions using the same stimulus every time (such as a ticking metronome).
The same instructions were issued to all Pp’s, and this allowed procedures to be replicated every time.
His work was significant as it marked the separation of modern scientific psychology, from its broader philosophical roots.
A01
This early attempt to investigate the mind might be regarded by many as naive, but some of the methods and techniques Wundt and his co-workers used would nevertheless be recognised as ‘scientific’ today. (A03)
Who critisised Wundt’s Introspection methods?
Page 105
John B. Watson (1913) criticized introspection for producing biased, inconsistent data that made generalization difficult. He argued that psychology should focus only on observable and measurable behaviors, not private mental processes.
A03
Thus, the behaviourist approach was born.
How did Watson and Skinner influence psychology, and how has the field evolved since their time?
Page 105
Watson (1939) and Skinner (1953) introduced the scientific methods of the natural sciences to psychology, focusing on learning processes through controlled lab experiments.
they were behaviourists, and behaviorism dominated for 50 years, especially after the 1960s.
Studying mental processes became even a key area of research, despite the ‘private’ nature of these processes, cognitive psychologists made inferences using lab data.
Today, The biological approach use experimental methods and advanced technologies like MRI and EEG to study brain activity and mental processes.
So while its scientific method remains central to psychology, its application has evolved significantly over time.
A03
private= while you can’t directly “see” someone’s thought process, you can observe their behavior in a controlled experiment and use that data to infer what might be going on in their mind. This is how cognitive psychology overcame the “private” / internal nature of mental processes, such as thoughts, memories, and perceptions.
Psychology’s early philosophical roots
Rene Descartes (1596-1650)
Page 104
A French philosopher, suggested that the mind and body are independent from each other.
- a philosophical stance that came to be known as Cartesian dualism.
(Since challenged, though it suggested that the mind could be an object of study in its own right.)
A01
Descartes demonstrated his own existence with the famous quote ‘I think therefore I am’.
Psychology’s early philosophical roots
John Locke (1632-1704)
Page 104
Locke proposed empiricism,
The idea that all experience can be obtained through the senses, and that human beings inherit neither knowledge nor instincts.
A01
This view would later form the basis of the behaviourist approach. That the world can be understood by investigating external events — that are observable and can be measured.
Psychology’s early philosophical roots
Charles Darwin (1809-1882)
Page 104
Darwin’s evolutionary theory - (survival of the fittest) suggests that behaviors evolve over generations. Individuals with adaptive traits, survive and reproduce .
A01
in psychology, the role of adaptive behaviors, is central to the biological approach.
Origins of psychology
What was psychology understood as in the 17th century - 19th century?
Page 104
experimental philosophy
A01
Origins of psychology- 1879
Page 104
Wilhelm Wundt opens the first experimental psychology lab in Germany.
A01
Origins of psychology- 1900’s
Page 104
Sigmund Freud publishes The interpretation of dreams, and the psychodynamic approach is established.
Freud emphasised the influence of the unconscious mind on behaviour, alongside development of his person-centred therapy: psychoanalysis (e.g dream anylsis therapy).
He argued that physical problems could be explained in terms of conflicts within the mind.
A01
Origins of psychology- 1913
Page 105
John B. Watson writes ‘Psychology as the Behaviorist Views It’ and B.F. Skinner’s work solidifies the behaviorist approach.
For the next fifty years, the psychodynamic and behaviorist approaches are the dominant perspectives in psychology.
A01
Origins of psychology- 1950s
Page 105
Carl Rogers and Abraham Maslow develop the humanistic approach - the so-called ‘third force in psychology, rejecting the views favoured by behaviourism and the psychodynamic approach.
Humanistic psychologists emphasise the importance of self-determination and free will.
A01
behaviourism and the psychodynamic approach: That human behaviour was not determined by the individual.
Origins of psychology- 1960s
Page 105
The cognitive revolution:
Came with the introduction of the digital computer, a metaphor for the operations of the human mind.
The cognitive approach reintroduces the study of mental processes to psychology but in a much more scientific way than Wundt’s earlier investigations.
Also around the time of the cognitive revolution,
Albert Bandura proposes the social learning theory. This approach draws attention to the role of cognitive factors in learning, (providing a bridge between the newly established cognitive approach and traditional behaviourism).
A01
Origins of psychology- 1980s onwards
Page 105
The biological approach begins to establish itself as the
dominant scientific perspective in psychology.
This is due to advances in technology that have led to increased understanding of the brain and the biological processes.
A01
Origins of psychology- Near the end of the 20th century
Page 105
Cognitive neuroscience emerges as a distinct discipline bringing together the cognitive and biological approaches.
Cognitive neuroscience is built on the earlier computer models and investigates how biological structures influence mental states.
A01
Behaviourist approach definition:
Page 106
A way of explaining behaviour in terms of what is observable and in terms of learning.
A01
Classical conditioning definition:
Page 106
Learning by association,
Occurs when two stimuli are repeatedly paired:
an unconditioned stimulus (UCS), which naturally triggers a response, and a neutral stimulus.
Over time, the neutral stimulus alone starts to trigger the same response that was originally caused by the unconditioned stimulus
A01
Operant conditioning definition:
Page 106
A form of learning, in which behavior is influenced and reinforced by its consequences:
Possible consequences of behaviour include positive reinforcement, negative reinforcement or punishment.
A01
Reinforcement definition:
Page 106
A consequence of behaviour that increases the likelihood of that behaviour being repeated.
A01
Can be positive or negative.
What were the assumptions made in the behaviourist approach?
Page 106
They were only interested in studying behaviour that can be observed and measured - not concerned with investigating mental processes of the mind.
Early behaviourists such as John B. Watson (1913) rejected introspection as it involved too many concepts that were vague and difficult to measure.
As a result, behaviourists tried to maintain more control and objectivity within their research and relied on lab experiments as the best way to achieve this.
Following Darwin, behaviourists suggested that the basic processes that govern learning are the same in all species.
This meant that in behaviourist research, animals could replace humans as experimental subjects.
Behaviourists identified two important forms of learning: classical conditioning and operant conditioning.
A01
What is classical conditioning?
Page 106
Procedure + findings ( Also, who came up with it?)
Classical conditioning is learning through association and was first demonstrated by Ivan Pavlov.
Procedure:
He revealed that dogs could be conditioned to salivate to the sound of a bell if that sound was repeatedly presented at the same time as they were given food.
Gradually, Pavlov’s dogs learned to associate the sound of the bell (a stimulus) with the food (another stimulus) and would produce the salivation response every time they heard the sound.
Findings:
Thus, Pavlov was able to show how a neutral stimulus, in this case a bell, can become a conditioned response through association.
