Cognitive behavioural therapy
The CBT approach assumes that emotions, behaviours and physical symptoms (which are core components of common psychological disorders) are influenced by thoughts, beliefs and images that exist in individualsâ minds. These mental processes are termed âcognitionsâ.
A classic example of this process in action is illustrated by the following situation: imagine that you are walking along a street and you notice that an acquaintance is approaching, walking towards you but on the other side of the street. You try to catch their attention but, rather than wave back, this person carries on walking without acknowledging you, with their head remaining bowed down. Let us suppose the thought then goes through your mind: âWhat have I done to upset them, why doesnât this person like me?â These cognitions might naturally cause you to become worried about your relationship with that person and more generally about how others perceive you. You might later also experience some physical symptoms that commonly accompany worry such as difficulty sleeping and restlessness while the matter plays on your mind. Now, let us imagine an alternative cognitive response to the situation. In this instance, you think instead: âThey seem preoccupied, I wonder what is concerning them?â This line of thought is likely to have impacted less on your mood because it is enquiring about their situation rather than reflecting negatively on your own. As such, it will probably lead to a different course of action, perhaps contacting the acquaintance to check if they are in any difficulty.
The CBT approach provides a framework for understanding how individualsâ interpretations of events may lead to the development and maintenance of psychological disorders (such as depression and anxiety). CBT treatment then involves the use of techniques to change dysfunctional patterns of cognition and behaviour that are central to such psychological difficulties. This approach emerged in the 1950s and 1960s, both arising out of âbehavioural approachesâ that were popular at the time and as a reaction to âpsychoanalytic psychotherapyâ. Before investigating CBT further, I first explore these therapeutic approaches to help us to understand its roots.
Psychoanalytic psychotherapy
Psychoanalytic psychotherapy has been in existence for over a century and, over this time, it has developed into numerous models of the mind and human nature. Therefore, you should bear in mind that below is a brief, basic summary of one (the Freudian) model that is informed by Atkinson et al. (1990) and also Smith (1995). The psychoanalytic approach assumes that various tensions or conflicts exist within an individualâs psychological âmake-upâ or personality. These conflicts arise as a result of competing demands made by three different components that exist in the personâs mind. These are termed: id, ego and super-ego. The id develops earliest in life and consists of our basic impulses, motivations and drives (for example, the need to eat and to gain sensual pleasure). Later, as infants, we learn that these impulses cannot always be satisfied immediately, and we develop another element or aspect to our personality: the ego. This is essentially the manager of the id. It juggles the competing demands of the id, the real world and also the super-ego. The super-ego consists of the values and morals of society that are taught to the child by their parents and other adults. This is the part of the mind that rewards the individual for being good and punishes them for being bad.
Sigmund Freud (1856â1939) was the principal originator of this approach (in the late 19th century). He proposed that some difficulties emerged from tensions or conflicts between these elements. He also pictured the mind as having a similarity to an iceberg. Most of the iceberg is not visible because it is below the waterâs surface. Similarly, much of the activity of the human mind occurs below the surface of our consciousness, therefore occurring on an unconscious level. When there is a severe conflict, the ego can protect the individual by pushing it into the unconscious. So, for instance, an anxiety disorder might be fuelled by the presence of unconscious, unacceptable or dangerous impulses that are kept in check (or repressed) because they might impact upon a personâs self-esteem or relationships. However, this is not a permanent solution and this unconscious material exerts pressure. At times this finds expression through irrational behaviour, dreams and possibly psychological difficulties if the ego is unable tosufficiently manage the situation.
Psychoanalysts seek to help their clients by bringing their conflicts into their awareness, ideally transforming symptoms into insights. They attempt to uncover the unconscious conflicts through use of techniques that facilitate their expression. These include:
- free association â unconscious conflicts can be revealed by the client saying what comes into their mind without any conscious editing;
- dream analysis â dreams are considered to contain unconscious desires in a disguised form;
- analysis of âtransferenceâ responses â the clientâs unconscious feelings towards the therapist mirror childhood responses to parents that can explain the origins of conflicts; and
- interpretation â the client is helped to develop insight by the analyst feeding back or interpreting the understanding that they have learned about the clientâs resistance and motivations.
The process of psychoanalysis is lengthy and intense. It traditionally involves therapy sessions for several times a week, for at least a year and often longer. Its protagonists believe that, as unconscious material is brought to light and understood, symptoms are dissipated.
In understanding the historical development of CBT, I draw on Morrey (1995) as well as France and Robson (1997). CBT pioneers such as Albert Ellis (1913â2007) and Aaron Beck (1921â) were originally psychoanalytic psychotherapists who, in the 1950s and 1960s, came to understand that there were radically different ways to make sense of clientsâ psychological difficulties. Another key individual is the clinical psychologist, George Kelly (1905â1967). He also developed an approach in 1955 that emphasised certain principles that were common to CBT. I focus below on Beckâs model because historically it has been the most popular form of CBT practised in the UK (Morrey, 1995). However, it needs to be noted that there have been other contemporary CBT approaches that remain popular (for instance, RationalâEmotive Therapy). There have also been important developments in the field of CBT in recent years (such as mindfulness-based CBT).
Beck originally sought to experimentally investigate the psychoanalytic proposition that depression was fuelled by repressed hostility. He did this by surveying the dream content of depressed individuals. His results contradicted this hypothesis and he found that their dreams were characterised by pessimism rather than anger. Likewise, within his therapy sessions, when clients were asked to free associate, the content of thisprocess was not always of relevance to what was hypothesised to be the roots of their difficulties. Rather, their thoughts revolved around more immediate reactions to their situation, such as worrying about how Beck would judge a comment that they had made. Upon further investigation, he found that many depressed clients reportedexperiencing these types of thoughts and that they seemed to occur as much in their everyday lives as in the therapy session. He labelled these as âautomatic thoughtsâ because they occurred rapidly and fleetingly without conscious prompting. While some of the thoughts were plausible, many seemed irrational or without basis, yet at the moment they occurred they were accepted unquestioningly by the client. They were often negative in nature and hence became known as negative automatic thoughts. Beck came to see these patterns of thinking as a distorted lens through which clients saw both themselves and their surroundings. He helped his clients to explore a method of correcting these patterns by challenging these thoughts with questions such as: âWhat is the evidence for ⌠[their interpretation of an issue or situation]?â and âIs there an alternative explanation?â He found that, as clients used this technique to develop an alternative perspective, their difficulties rapidly improved â these observations forming the early building blocks of CBT (Beck, 1976).

Behaviour therapy
âBehaviour therapyâ refers to a number of different therapeutic approaches based on the principles of learning, which were established in the early to mid-twentieth century. Learning theory pioneers such as Ivan Pavlov (1849â1936) and Burrhus Skinner (1904â1990) found that animals and humans alike learn in two primary ways. Together, these form the building blocks of learning (Atkinson et al., 1990). The first of these is termed classical conditioning and refers to learning that one event will follow another. For example, a baby learns that milk will follow from the sight of a breast. In his classic experiment, Pavlov retrained a dogâs salivation response. Naturally, when a dog sees food (the food in this context is termed an âunconditioned stimulusâ), it salivates (an âunconditioned responseâ to this stimulus because it is a natural one). However, let us suppose a bell (a âneutral stimulusâ) is also rung each time that the food is presented. Over time, the dog will associate the bell with the food and then salivate to the sound of the bell alone (this then becomes a âconditioned responseâ to the âconditioned stimulusâ â the bell).
The second form of learning is termed operant conditioning and refers to learning that a behaviour will be followed by a consequence. For example, a child learns that hitting a sibling will result in disapproval from a parent. Skinner found that, if an animal is given a reward (such as food) after performing a behaviour (like pressing a lever), the frequency of that behaviour increases dramatically. In this way, rewards (or âreinforcementsâ) increase the rate of behaviour occurrence. There are two types of reinforcement: positive and negative. Positive reinforcement occurs when a behaviour increases or is strengthened following the provision of a satisfying stimulus. So, a person might work harder or take on more duties if they are paid more. Negative reinforcement occurs when a behaviour increases or is strengthened as the result of taking away an unpleasant stimulus. In this way, a person might learn to improve poor work performance in order to avoid disapproval from their manager or take aspirin to remove a headache. Punishment differs from reinforcement in that it consists of providing an unpleasant stimulus after a behaviour (for example, slapping a child for throwing some food). This will tend to suppress the behaviour. However, as punishment fails to convey an appropriate alternative behaviour, its effects can be unpredictable. In addition, it can instil fear and aggression, and so for these reasons it is seen as a less effective form of learning. Later, psychologists also identified learning that occurs through observing others (Bandura, 1973).
Aspects of the development and maintenance of clinical difficulties can be understood in terms of learning theory. For example, a phobia might be developed through classical conditioning. This was demonstrated by John Watson (1878â1958) when he introduced a nine-month-old baby (Little Albert) to a number of objects (including a rat). Initially, Albert did not exhibit fear in response to these. However, as Albert was subsequently introduced to these objects, a loud and frightening sound was made. Consequently, Albert made a link between the conditioned stimulus (the rat) and the conditioned response (fear), illustrating a mechanism for the development of a phobia. Clients sometimes report similar origins to their own phobias. A phobia of public transport might develop after experiencing an extremely humiliating experience on a bus such as involuntary defecation. Fear may then be maintained by operant conditioning as the avoidance of aversive states is reinforced through avoidance of the feared stimulus (Mowrer, 1947). This can be illustrated with the example given above where, by avoiding public transport, the person does not experience the high anxiety associated with this situation. This encourages them to continue to avoid public transport in the future.
Exercise 1.2 The application of learning theory
A mother is travelling on a bus with her 4-year-old son. The son has a temper tantrum because he is bored and wants to go home to play with his toys. The mother, feeling embarrassed, removes her son from the bus, abandons her trip and takes him home. Which behaviour is being reinforced? What form of reinforcement is being used?
When the mother and child get home, the child quietly plays with his toys. At this point, the mother shouts at her son for embarrassing her earlier. Despite the motherâs intentions, which behaviour is actually being punished at that point?
Is the motherâs behaviour helping the child? If not, give some thought to what responses would be more helpful for him.
Behaviour therapy uses the principles of learning theory in order to help people to overcome their psychological problems. For instance, the treatment of phobias involves a process of deconditioning. This approach was termed âsystematic desensitisationâ (Wolpe, 1969) an...
