Paper 2 - Approaches Flashcards
Define controlled procedures
The same standardised instructions were given to all participants and stimuli were presented in the same order
Define Structuralism
An experience is scientifically analysed in terms of its components, focusing on the mental functions of thoughts, images and sensations
Who is Wilhelm Wundt and what did he contribute
Wundt, known as ‘the father of psychology’ and he set up the first psychology laboratory. The laboratory had the primary objective to document and describe human consciousness
Wundt’s work is significant because it marked the beginning of scientific psychology
He introduced the idea of structuralism and the use of introspection as well as reductionism. His work paved the way for later controlled research
Evaluate Wundt’s Contribution to Psychology
One strength of Wundt’s work is that some of this methods were systematic and well-controlled. All introspections were recorded in the controlled environment of the lab, ensuring that possible extraneous variables were not a factor. This suggests that Wundt’s research can be considered a forerunner to later scientific approaches in psychology, such as behaviourist approach
One limitation is that other aspects of Wundt’s research would be considered unscientific today. Wundt relied on participants self-reporting their mental processes. Such data is subjective. Also participants may ahve hidden some of their thoughts. It is difficult to establish meaningful ‘laws of behaviour’ from such data. This suggests that some of Wundt’s early efforts to study the mind were flawed and would not meet the criteria of scientific enquiry
Define introspection and explain what principles it is based on
The first systematic experiemental attempt to study the mind by breaking down the conscious awareness into basic structures of thoughts, images and sensation
Determined- all behaviour is seen as being caused
Predictable- it is possible to predict how human beings would behave in different conditions
What research went into introspection
Introspection involved Wundt training participants to focus on an everyday object and look inwards, noticing sensation’s feelings and images
He strictly controlled the environment where introspection took place:
- Stimuli (e.g. images or sounds)
- Tasks (e.g. a description of their perception or emotions) that participants were asked to consider
This allowed for an objective and systematic reporting of an experience of an object

Evaluate the emergence to psychology
One strength is that research into modern psychology can claim to be scientific. Psychology has the same aims as the natural sciences. The learning, cognitive and biological approach all rely on the use of scientific methods. This suggests that throughout the 20th century and beyond, psychology has established itself as a scientific discipline
One limitation with psychology with psychology is that not all approaches use objective methods. The humanistic approach rejects the scientfic approach, preferring to focus on individual experinces and subejctive experience. The psychodynamic appproach makes use of the case study method which does not use representative samples. Finally, the subject of study- human beings- are active participants in research, responding for example to demand characteristics. Therefore a scientific approach to the study of human thought and experience may not always be desirable or possible
Outline the Key assumptions in the Behaviourist Approach
- A focus on the observable behaviour - Only behaviour that can be observed and measured should be studied. not concerned with studying mental processes. (Rejects introspection.)
- A focus on scientific and experimental methods - maintain control and objectivity in their research. Therefore, they relied on laboratory experiments for their research
- The basic processes that govern learning are the same in all species - this means that behaviourists often use animals in research in place of humans as they believe results can be generalised across species (e.g., the principles of classical conditioning and operant conditioning).
Outline Classical Conditioning in the behaviourist approach
- Classical Conditioning - “Learning by Association” - Pavlov’s Dogs
- It occurs when two stimuli are repeatedly paired together – an unconditioned (unlearned) stimulus (UCS) and a new ‘neutral’ stimulus.
- The neutral stimulus eventually produces the same response that was first produced by the unlearned stimulus alone.
Pavolv’s dogs learned to associate the sound of the bell ( a stimulus) with the food (another stimulus) and would produce the salivation repsonse every time they heard the sound. Thus Pavlov was able to show how a neutral stimulus, in this case a bell, can come to elicit a new response (conditioned response) through association
Outline how phobias are acquired using Little Albert study
- Watson and Rayner (1920) demonstrated the learning of a phobia through classical conditioning in a boy called ‘Little Albert’.
- Stimulus Generalisation - occurs when an organism’s response previously conditioned by one stimulus can then be evoked by another stimulus having similar characteristics
White Rat (Neutral stimulus) ——— No response ( Neutral response)
Loud noise (Unconditioned stimulus) ——— Fear response (Reflex)
White rat + Loud Noise (Neutral stimulus + unconditioned stimulus) ———– Fear response (Reflex)
White rat ( Conditioned Stimulus) ——– Fear response (Conditioned response)
(e.g. Little Albert having the same conditioned response when presented with anything white and fluffy - Watson with a white Santa beard).
What principles is Operant Conditioning Research based done
Operant conditioning is based on the following principles:
* Positive reinforcement: receiving a reward (something good) for a behaviour increases the likelihood of that behaviour being repeated in the future.
* Negative reinforcement: when a behaviour leads to an unpleasant aspect being avoided/removed. Again, this makes the behaviour more likely to be seen in the future
* Punishment: if a behaviour is followed by an unpleasant consequence, the behaviour will be less likely to be repeated in the future.
Outline Skinner Research into Operant conditioning
Skinner conducted experiments with rats. and sometimes pigeons, in specially designed cages called Skinner boxes. Every time the rate activated a level within the box it was rewarded with a food pellet. From then on the animal would continue to perform the behaviour.
Skinner also showed how rats and pigeons could be conditioned to perform the same behaviour to avoid an unpleasant stimulus. for example a electric chock
Food pellet - Positive reinforcement
Electric shock - negative reinforcement
Briefly outline what is meant by stimulus generalisation
Stimulus Generalisation - occurs when an organism’s response previously conditioned by one stimulus can then be evoked by another stimulus having similar characteristics
(e.g. Little Albert having the same conditioned response when presented with anything white and fluffy - Watson with a white santa beard).
Outline the contribution of Pavlov and Skinner into understanding human behaviour
Pavlov and Skinner’s research (and theories) contributed greatly to psychology as they enhanced our understanding of human behaviour:
- It Made psychologists appreciate how behaviour is learnt and environmentally determined
- They emphasised the need for large-scale data gathering, which is desirable in science. This also allowed for generalisation, which, in turn, led, to the development of laws and principles
- They gave us theories of learning and laws of learning (classical and operant conditioning) that emphasised the importance of consequences (behaviour that is rewarded likely to be repeated)
- Their theories have been practically applied in many fields, such as therapy and education
Evaluate the Learning Approach Behaviourism
One strength of the behaviourist approach is that it is based on well-controlled research. Behaviourists focused on the measurement of observable behaviour within highly controlled lab settings. By breaking down behaviour into basic stimulus- response units, all other possible extraneous variables were removed, allowing cause-and effect relationships to be established. For instance, Skinner was able to clearly demonstrate how reinforcement influenced an animal’s behaviour. This suggests that behaviourist experiments have scientific credibility
Another strength of the behaviourist approach is that the principles of conditioning have been applied to real-world behaviours and problems. For example, operant conditioning is the basis of token economy systems that have been used successfully in institutions. such as prisons and psychiatric wards. These work by rewarding appropriate behaviour with tokens that can be exchanged for privileges. This increases the value of the behaviourist approach because it has widespread application
One limitation of the behaviourist approach is that it sees all behaviour as conditioned by past conditioning experiences. Skinner suggested that everything we do is the sum total of our reinforcement history. According to Skinner, our past conditioning history determined the outcome. This ignores any possible influence that free will have on behaviour (skinner himself said that free will is an illusion). This is an extreme position and ignores the influence of conscious decision making processes on behaviour
Outline the key assumption in Soical learning theory
“Learning by Observation”
The key difference is that SLT argues mental processes influence our responses to stimuli.
- People learn through observation and imitation
- Bandura’s SLT argues people learn through experiences; however, SLT argues learning is social and can occur directly (e.g. through classical and operant conditioning)
Also also indirectly through observation and imitation and vicarious reinforcement.
Outline Vicarious reinforcement in the Social Learning Theory
Vicarious reinforcement is key:
* Vicarious reinforcement is when the reinforcement is not experienced directly by a person but when a person observes someone else being reinforced for a behaviour.
* A person must observe the behaviour of a model (another person). They will then imitate the observed behaviour but only if the observed behaviour is seen to be rewarded / rewarding (the learner observes and takes note of both the observed behaviour and the consequence of the behaviour).
What is the role of Cognitive mediational processes in the Social learning theory
It focuses on how mental (cognitive) factors are invovled in learning. These mental factors mediate in the learning process to determine wether a new resposne is acquired. Four mental or mediaitonal processes in learning thery:
- Attention: the extent to which we notice (are paying attention) certain behaviours
- Retention: how well behaviour is / can be remembered
- Reproduction: the ability of an observer to perform the behaviour
- Motivation: whether a person is motivated to perform the observed behaviour (influenced by whether they observe the behaviour being rewarded or punished).
How does the identification play a role of Social Learning Theory
People are more likely to imitate models with whom they identify, what we call role models. This process is called modelling.
Bandura’s research demonstrated that models who are most likely to be imitated will be:
- same sex
- similar age to the observer
- likeable/respected
- high status (powerful)
