Free Will And Determinism Flashcards
What is free will?
The idea that we are self-determining. The notion of free will suggests human beings are free to choose their thoughts and actions. There are biological and environmental influences on our behaviour - but free will implies we can reject them. This is the view of the humanistic approach.
What is hard determinism?
All human action has a cause - it should be possible to identify these causes. This is compatible with the aims of science which assume that what we do is dictated by internal or external forces that we cannot control.
What is soft determinism?
All human action has a cause but people have conscious mental control over behaviour. James thought scientists should explain the determining forces acting upon us, but we still have freedom to make choices.
Biological determinism is control from physiological, genetic and hormonal processes.
The biological approach:
- Physiological processes are not under conscious control, (e.g. Influence of autonomic nervous system on anxiety).
- Genetic factors may determine many behaviours and characteristics (e.g. Mental disorders).
- Hormones may determine many behaviours and characteristics (e.g. The role of testosterone in aggressive behaviour).
Environmental determinism explains that we are determined by conditioning.
The behaviourist approach popularised the idea of environmental determinism - Skinner Skinner said free will is ‘an illusion’ and argued all behaviour is a result of conditioning. Our experience of ‘choice’ is just the sum total of reinforcement contingencies that have acted upon us throughout our lives. We might think we are acting independently, but our behaviour has been shaped by environmental events and agents of socialisation (parents, teachers, institutions, etc.)
Psychic determinism explains that we are directed by unconscious conflicts.
Like Skinner, Freud thought free will is an illusion but placed emphasis on biological drives and instincts underpinning psychological responses rather than conditioning. Freud’s psychic determinism sees behaviour as determined and directed by unconscious conflicts repressed in childhood. For example, even a seemingly random ‘slip of the tongue’ is determined by the unconscious.
How does science try to find causal explanations where one thing is determined by another?
A basic principal of science is that every event has a cause and those can be explained with general laws. Knowledge of these allows scientists to predict and control events. In chemistry, adding a chemical X to a chemical Y results in a reaction Z within the controlled environment of the test tube. In other words, the behaviour of Z is determined by X and Y. In psychology, the lavatory experiment lets researchers simulate the conditions of the test tube and remove all other extraneous variables to demonstrate a causal effect.
Strength: it is consistent with the aims of science.
The notion that human behaviour is orderly and obeys laws places psychology on equal footing with other sciences, increasing its credibility. Another strength is that the prediction and control of human behaviour has led to the development of treatments and therapies (e.g. Drug treatments to manage schizophrenia). The experience of schizophrenia (loss of control over thoughts and behaviour) suggests some behaviours are determined (no one ‘chooses’ to have schizophrenia).
Limitation: hard determinism is not consistent with the legal system.
Offenders are morally accountable for their actions in law. Only in extreme circumstances are juries instructed to act with leniency (e.g. When the Law of Diminished Responsibility is applied in cases of mental illness). Another limitation is that determinism as an approach to scientific enquiry is not falsifiable. It is based on the idea that causes of behaviour will always exist, even though they may not yet have been found. As a basic principle this is impossible to disprove. This suggests that the determinist approach may not be as scientific as it first appears.
Strength of free will: we often make choices in everyday life.
Everyday experience ‘gives the impression’ that we are constantly making choices on any given day. This gives face validity to the idea of free will (i.e. It makes sense). Another strength is that, even if we do not have free will, the fact that we think we do may have a positive impact on mind and behaviour. Roberts et al showed that adolescents with a strong belief in fatalism (that their lives were ‘decided’ by events outside their control) were more at risk of depression.
Limitation of free will: it is not supported by neurological evidence.
Brain studies of decision-making have revealed evidence against free will - and slightly disturbing evidence. Liver and Soon found that the brain activity related to the decision to press a button with the left or right hand occurs up to 10 seconds before participants report being consciously aware of making such a decision. This shows that even our most basic experiences of free will are decided and determined by our brain before we become aware of them.
Strength: a compromise in the middle-ground position.
Approaches in psychology that have a cognitive element (e.g. Social learning theory) are those which tend to adopt a soft determinist position. Bandura argued that although environmental factors in learning are key, we are free to choose who or what to attend to and when to perform certain behaviours. This middle-ground approach is helpful in understanding aspects of human behaviour which are not a straightforward choice between free will and determinism (e.g. Learning).
