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
Nature v Nurture debate
-Nurture definition
-Nurture refers to all the environmental variables that impact who we are, including our early childhood experiences, how we were raised, our social relationship, and our surrounding culture
-Empiricism -> The nurture side of the debate
-Tabula rasa (a blank slate at birth) was created by John Locke
The Nurture v Nature debate
-Introduction
-The debate has adapted from nature v nurture, to how much nature and nurture is responsible for our behaviour
-The interactionist approach has developed from the argument and is the view that both nature and nurture work together to shape human behaviour and account numerous factors (e.g. environment, genetic inheritance etc)
The Nurture v Nature debate
-The relative importance of heredity and the environment
-Heredity refers to the genetic transmission of mental and physical characteristics from one generation to another
-Environment is any influence on human behaviour that is non-genetic (this may range from prenatal influences in the womb to cultural and historical influences in society)
-Epigenetics -> small changes make large differences
-The Heritability Coefficient -> It is used to assess heredity. It is a numerical figure ranging from 0 to 1.0 which indicates the extent that the characteristic has a genetic basis (a value of 1 means it is entirely genetically determined). An example is that the general heritability for IQ is accepted to be 0.5, suggesting that both genetics and the environment are important factors that influence IQ
Nature v Nurture debate
-The interactionist approach
-The diathesis-stress model is a model of mental illness that influences the interaction of nature and nurture influences. The model states that both a genetic predisposition to a mental disorder and environmental stressors are necessary for a condition to affect an individual
-What is inherited in some cases of mental disorders is a predisposition to be vulnerable to it, not the disorder itself
-Epigenetics refers to a change in our genetic expression without changing our genetic code. It is a process that happens throughout our life and is caused by interaction with the environment
-Aspects of our environment and lifestyle (e.g. smoking, diet) leave epigenetic marks on our DNA. These marks tell our bodies which genes to use and which to ignore
Gender and culture in psychology
-Universality and bias
-Universality refers to when research assumes the findings can be applied to both genders equally, or to all cultures equally
-There are 3 types of bias; androcentrism, alpha and beta bias
-Androcentrism -> This refers to theories which are centered on males or focused on males only. This can occur if all male samples are used in research and then a theory is generated from research which is applied to both genders
-Alphas bias -> This occurs when the differences between men and women are exaggerated
-Beta bias -> This occurs when the differences between men and women are minimised (Rosenthal 1966 reported that male experimenters were more pleasant, friendly, honest and encouraging with female than male participants- this concludes that male and female subjects may, psychologically, not be in the same experiment at all.
Gender and culture in psychology
-Cultural bias
-Culture bias -> The act of interpreting and judging behaviour and psychological characteristics of one culture by holding them to the standards of your own
-Ethnocentrism -> Inappropriately generalising the values and research findings of one culture to another without bothering to test other cultures (can cause cultural bias)
-An etic approach may amplify cultural bias. This is where research is carried out across cultures in order to discover what elements of a behaviour might be universal (e.g. Berry). Berry argues that psychology is often guilty of making imposed etic, developing universal models and theories of human behaviour which come about through studying 1 specific culture
-Yerkes research that skewed African-American intelligence in WW1, lead to many African-Americans being refused promotions
Gender and culture in psychology
-Cultural relativism
-Cultural relativism is the belief that you need to consider the behaviour being studied and the context it is in
-One way to overcome the problem could be to employ an emic approach, to help reduce cultural bias
-It refers to research that aims to study human behaviour in 1 culture, without applying the behaviour elsewhere
-A problem with this is that it is very hard to get a true understanding of the culture if you are not a member of it, especially when carrying out experiments where there is limited contact, and usually a small sample e.g. Fiji men prefer larger women, which is unknown about if you’re not from Fiji
Idiographic and Nomothetic approaches
-Intro/basics
-The debate refers to the question about whether psychology should focus its attention on the individual or people in general
-Should psychology aim to produce generalities against which people should be compared or measured or should it be concerned what makes people unique
Idiographic and Nomothetic approaches
-The idiographic approach
-This approach attempts to explain the nature of individuals. It argues people should be studied as unique entities, each with their own subjective experiences, motivations and values that contribute to individual development
-The idiographic approach is normally associated with methods that produce qualitative data, such as; non-numerical data, verbal expression (thoughts and feelings) and results can be produced as quotes
-You cannot make generalisable laws with this approach
