Approaches Flashcards
Wilheim Wundt
-First perosn to call himself a ‘psychologist’.
-He said ‘ALL aspects of human nature including the human mind & behaviour can be studied scientifically.
-His method was called introspection: first systematic experimental attempt to study mind by breaking up conscious awareness into basic structures of thoughts, images & sensations.
What is a ‘scientific approach’?
Based on 2 approaches:
1. All behaviour is seen as being caused (determined).
2. If behaviour is determined, it should’ve be possible to predict how humans will behave in diff conditions (predictability).
Refers to use of investigative methods:
-objective: not influenced by personal feelings in considering & representing facts.
-systematic: done or acting according to a fixed plan (methodical).
-replicable: with ability to reproduce.
Introspection
-looking inwards.
Method of studying mind.
-trained his graduate researchers to make personal observations that were biased & based on experience.
E.g. reflective of their working mind.
-based around sensory perceptions & attention.
E.g. ppts would be exposed to standard stimulus & asked to report sensations.
structuralism: stimuli that Wundt & his Co workers experienced were always presented in the same order & same instructions issued to all ppts.
Evaluation of Introspection
:) systematic & well controlled.
:) excluded extraneous variables.
:) started foundation of psychology as a science.
:( not credible.
:( relies on someone else’s account.
:( bias.
:( unscientific today.
:( Griffiths (1994) asked gambles to think about whilst playing a fruit machine to see if their thought processes were more irrational. & they were.
Psych over time: 17-19th century
Psychology is a branch of the broader discipline of philosophy. If psych has a definition in this time, it is as experimental philosophy.
Psych over time: 1879
Wundt opens the 1st experimental psychology lab in Germany, & psych emerges as a distinct discipline in its own right.
Psych over time: 1900s
Freud emphasised influence of the unconscious mind on behaviour (the psychodynamic approach).
He also develops his person-cantered therapy psychoanalysis, & shows that physical problems can be explained in terms of conflicts within the mind.
Psych over time: 1913
John B. Watson writes psychology as the behaviourist views it & layer with B.F. Skinner, establishes the behaviourist approach.
The psychodynamic & behaviourist approaches dominate psychology for 1st half of the 20th century.
Psych over time: 1950s
Carl Rogers & Abraham Maslow develops the humanistic approach the so called ‘third force’ in psychology, rejecting the behaviourist & psychodynamic view that human behaviour is determined by outside factors.
Humanistic psychologists emphasise importance of self-determination & free will.
Psych over time: 1950s
The introduction of the digital computer gives psychologists a metaphor for the operations of the human mind.
The cognitive approach reintroduces the study of mental processes to psych but in a much more scientific way than Wundt’s earlier investigations.
Psych over time: 1960s
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 & traditional behaviourism.
Psych over time: 1980s onwards
The biological approach begins to establish itself as the dominant scientific perspective in psychology.
This is due to advances in tech that increased understanding of the brain & biological processes.
Psych over time: Eve of 21st century
Towards the end of the last century, cognitive neurosciences emerges as a distinct discipline bringing together the cognitive & biological approaches.
Cognitive neurosciences investigated how biological structures influence mental states.
1900s Behaviourists
-By 20th century, value of introspection was questioned, notably by Watson who said the data was very subjective so it’s difficult to establish general laws.
-Skinner proposed that for psych to be scientific, the experiments should be observed objectively & measured.
1950s Cognitive approach
Digital revolution meant new gen of psychologists compared studying the mind to studying a computer & tested predictions about memory with experiments which insured the study was legitimate & disciplined.
1980s Biological approach
-Researchers have taken advantage of advances in tech to investigate psychological process.
E.g. use of sophisticated scanning techniques such as fMRI & EEG to study live activity in the brain.
-New methods like genetic testing have helped understand relationship between genes & behaviour.
Evaluation of Emergence of psychology as a science - Modern psychology
:) Scientific - psych has the same aims as natural sciences (describe, understand, predict & control behaviour).
Learning approaches use lab studies to investigate in a controlled & unbiased way.
Evaluation of Emergency of psychology as a science - Subjective data
:( Not all approaches use objective methods.
Humanistic approach uses individuals & subjective experiences.
Psychodynamic approach makes use of unrepresentative samples.
& Humans are active ppts & respond to demand characteristics.
Therefore, a scientific approach may not always be possible.
Focus on the environment
Learning approach states that the environment shapes our behaviour and we are born “tabula rasa” (clean slate).
Not interested in biological explanations.
Focus on scientific methods
Learning approach says behaviour should be studied in a scientific way by isolating & studying specific actions.
Strong focus on observable events.
What do learning approaches say we learn through?
-Imitation: social learning theory.
-Consequences for actions: operant conditioning.
-Association: classical conditioning.
How does Classical conditioning work?
-association
-passive
-Occurs when a neutral stimulus which wouldn’t normal cause a response is associated with an unconditioned stimulus whcih naturally cause a reflex. -This is called an unconditioned response.
-The NS is associated with the UCS so it causes the UCR to occur even when presented with the NS only.
-The NS is now a conditioned stimulus & it causes a conditioned response.
Classical conditioning - Pavlov’s dogs
Pavlov showed how dogs could be conditioned to salivate to the sound of a bell if the sound was repeatedly presented at the same time as they were given the food.
They learnt to associate the sound of the bell (NS) with the food (UCS) & produce salivation every time they were presented with the sound.
Thus, this shows how NS can created a conditioned response through association.
Operant conditioning
Skinner suggested learning is an active process whereby humans & animals operate on the environment.
Behaviour is shaped by consequences.
