Issues and Debates Flashcards
Free will and Determinism
-Determinism definition
-Determinism proposes that all events, including human action, have no to little control over behaviour
-Behaviour is determined by causes regarded as external to the will
-Most/all of psychology believes in determinism
Free will and Determinism
-Free will definition
-Free will suggests that we have full choice over our actions without influence or manipulation
-Free will is very hard to test (scientifically)
-It is not empirical
-Humanism is the only branch that believes in free will. It believes we have ‘personal agency’, the ability to make up our mind irregardless of influence
Free will and Determinism
-Hard Determinism
-Hard determinism is completely determined by factors outside of a persons control
-For example, humans have no free will. They do not choose mental illnesses, as no humans would freely choose to have schizophrenia. This means they are determined due to the surrounding factors of an individual and others, such as genetic inheritance/genes
Free will and Determinism
-Soft determinism
-It is human behaviour which is generally determined by factors outside of their control but they have the option to exercise free will in certain situations
-For example, conformity could be regarded as being a soft determinist due to the illusion of choice in an environment that does not constrain our behaviour.
Free will and Determinism
-Biological determinism
-Behaviour is the result of internal processes; genetics, brain physiology and biochemistry
-Genetics are difficult to ignore. Genes do not cause behaviour, however they increase the likelihood of behaviour
-E.g. lots of dopamine causes schizophrenia (biochemistry is deterministic)
Free will and Determinism
-Environmental determinism
-Our behaviour is caused by our physical environment
-Parents play a large role in our development and behaviours
-E.g. The participants in Asch, Milgram and Zimbardo largely acted out of pressures from their environments. Their environment determined their behaviour.
Free will and Determinism
-Psychic determinism
-Our behaviour is caused or determined by our unconscious mind. This links to the psychodynamic approach
-E.g. Freud argued that every behaviour has an internal cause and that behaviour was initiated in a part of our mind that we cannot access
Free will and Determinism
-Scientific emphasis on causal explanations
-This refers to Psychology’s tendency to observe one variable affecting another
-Determinism is scientific. It allows you to clearly see one variable affect the other (empiricism)
-One of the basic principles of science is that every event in the universe has a cause and that causes can be explained using general laws
-Causal explanations are established with the following criteria:
1. All variables, such as confounding and extraneous variables, are controlled for
2. Any differences in the DV’s must therefore be down to the IV’s
3. As a result, researchers can then infer that the IV clearly affected the DV
Holism and Reductionism
-Reductionism definition
-It is the idea that when a complex behaviour is reduced down to a single variable cause, you are reducing behaviour down to it being cause by one thing
-If the behaviour is suggested to be caused by a single variable = reductionism
-Reductionism works on the idea of parsimony which argues, by Morgan (1903), that there was no need to explain behaviour in terms of complex processes and that explanations should be made as simple as possible
Holism and Reductionism
-Holism definition
-It is the idea that behaviour should be viewed as complex and viewed as a whole part not as separate parts
-When several levels of explanation are used for a human behaviour
Holism and Reductionism
-Levels of explanation in psychology
-The notion of ‘levels of explanation’ suggests that there are different ways of viewing the same phenomena in psychology. The reductionist approach argues explanations begin at the highest level and progressively reduce to consider behaviours at component elements
Highest level -> Cultural and social explanations of how our social group effects our behaviour. Memory is influenced by cultural expectations
Middle level -> Psychological explanations of behaviour. Psychological factors influence memory e.g. elaborative rehearsal
Lower level -> Biological explanations. Biological aspects like genes and hormones affect our behaviour and influence memory
Holism and Reductionism
-Biological reductionism
-Biological reductionism is based on the premise that we are biological organisms made up of physiological structures and processes
-Because of this, behaviour is always at some level biological and can be explained through neurochemical activity, neurophysiology and evolutionary influence. This also means that biological measures can be used to record behaviour
-Biological reductionist measures include; biochemistry, genetics and neuroanatomy
Holism and Determinism
-Environmental (stimulus-response) reductionism description
-The behaviourist approach is built on environmental reductionism:
1. It suggests that only observable behaviour should be studied, and that all behaviour can be broken up into stimulus-response links that take place in a person’s environment and that these are also measurable within a laboratory
2. Because of this , behaviourists do not recognise psychological levels of explanation, such as the role of mental cognitions.
-An example of S-R reductionism is that when a snake comes towards you, you run away. We haven’t all had close contact to a snake but we know to remove ourselves so that we don’t get bitten (biological preparedness)
Holism and Determinism
-Environmental (stimulus-response) reductionism methods
-2 environmental reductionist methods;
- Social learning theory. Children will copy the behaviour of their role model (often a same-sex parent)
- The mother becomes the conditioned stimulus who becomes associated with the pleasure from feeding. The child therefore feels pleasure when near the mother. This leads to attachment
Nature v Nurture debate
-Nature definition
-Nature refers to all of the genes and hereditary factors that influence who we are - from our physical appearance to our personality characteristics
-Nativism -> The nature side of the debate
-Plato and Descartes suggested that certain things are inborn, or that they occur naturally regardless of environmental influences
