  • 42. Behavioural Explanations <br />Behaviourists argue that abnormal behaviour is<br />learnt in the same way that all behaviour is learnt <br />There are 3 learning theories that provide us with<br />explanations for phobias:<br />Classical conditioning<br />Operant conditioning <br />Social Learning theory<br />These may operate alone or in conjunction with each<br />other to explain the development of a phobia<br />Explanations for an Anxiety Disorder – Phobias<br />
  • 43. Classical Conditioning can explain the development of phobias:<br />
  • 44. Watson and Raynor conditioned an 11 month old<br />child Albert to have a phobia of white rats by<br />pairing playing with the rat with a loud noise ( a<br />metal sheet being hit by a hammer). Albert then<br />generalised this fear to other white fluffy<br />objects such as a rabbit’s tail and Father Xmas’<br />Beard.<br />Watson and Raynor (1920) – Little Albert and the White Rat<br />
  • 45. Operant conditioning is learning from the<br />consequences of actions.<br />Actions which have a good outcome through positive reinforcement (reward),will be repeated<br />Actions where there is negative reinforcement (the removal of something bad), will be repeated<br />Actions where there is no reinforcement tend to die out or be extinguished<br />Operant Conditioning - Skinner<br />
  • 46. Positive Reinforcement<br /> If someone is rewarded for showing a phobic reaction this could perpetrate the behaviour. E.g. A child who is frightened by a barking dog may get cuddles from their parents and continues with this response every time they see a dog. The pattern of behaviour becomes entrenched and is by definition unreasonable<br />Negative reinforcement<br /> When we get anxious around phobic stimuli heights, needles etc we avoid them. This prevents the anxiety and acts as negative reinforcement. Again the behaviour becomes entrenched.<br />Operant Conditioning and Phobias<br />
  • 47. There are 4 elements to SLT<br />Observation of behaviour<br />Imitation of observed behaviour<br />The people we are most likely to copy are similar to us and/or powerful and influential.<br /> People of the same sex, parents, siblings, peers and celebrities are the most influential role models<br />The behaviour we observe and imitate has to be reinforced.<br />Social Learning Theory – Bandura (Bobo Doll experiments)<br />
  • 48. If a child sees their mother being frightened of injections, they are likely to copy that fear response. If they then get rewarded with cuddles and a fuss this will reinforce the fear response.<br />Bandura and Rosenthal (1966) found that p’s would develop a fear reaction to a buzzer if they witnessed someone showing pain when the buzzer sounded. The research was carried out using confederates who pretended to be shocked at the sound of the buzzer.<br />SLT - Phobias<br />
  • 49. Strengths<br /><ul><li>It is scientific with testable concepts.
  • 50. It is supported by empirical evidence such as Little Albert and the Bandura study
  • 51. If behaviour is learned it can be unlearned and therefore anxiety disorders are treatable</li></ul>Limitations<br /><ul><li>It is reductionist because it ignores both the influence of cognition (thinking) and biology
  • 52. There are some aspects of anxiety disorders that cannot be explained by learning theory, such as individual differences in susceptibility to acquiring disorders
  • 53. There are ethical issues in both studies such as Little Albert and in treatments such as aversion therapy</li></ul>Strengths and limitations of the behavioural explanation<br />
  • 54. 2. Biological Explanations<br />There is no doubt that some of the symptoms of<br />anxiety disorders such as increased heart rate<br />and blood pressure are biological.<br />There is also some evidence that there are both<br />evolutionary and genetic explanations for anxiety<br />disorders.<br />Explanations for an Anxiety Disorder – Phobias<br />
  • 55. The evolutionary argument proposes that we have a biological preparedness which allows us to acquire phobias of some things such as snakes, spiders, heights more readily than others<br />Evolutionary theory suggests that behaviours that aid survival tend to evolve over time as people with this behaviour in their genes survive and those without die out.<br />People who have a phobic response to something dangerous, such as snakes, are more likely to avoid them and therefore survive to pass on their genes<br />Evolutionary explanations for phobias<br />
  • 56. Ohman et al <br />Wanted to see if phobias of snakes could be more easily conditioned than phobias of faces/houses<br />Lab experiment<br />Results showed p’s were more likely to show fear reactions to snakes supporting the theory of biological preparedness<br />Bennet-Levy & Martineau<br />Investigated what characteristics of animals humans are predisposed to fear<br />Correlation using self -report rating scales<br />One scale rated fear of various animals<br /> One scale rated 4 characteristics: ugliness, sliminess, speediness and how suddenly the animal moved<br />Results showed a correlation between the 4 characteristics and levels of fear supporting the idea of biological preparedness<br />Evidence for Biological Preparedness<br />
  • 57. Twin studies<br />Skyre et al (2000) studied concordance rates in 23 pairs mz and 38 pairs same sex dz twins<br />Identical twins more likely to share phobias<br />This effect was greater for agoraphobia<br />-Twin studies usually involve small samples<br />Family Studies<br />Harris et al (1983) found that where there was a mother/father/sibling with agoraphobia the risk of illness was twice that of the control group<br />Solyam et al (1974) found that 31% of phobics had a mother who suffered some kind of phobia and 55% had mothers and 24% had fathers with other anxiety disorders.<br />- Problems in families could be a result of SLT<br />Evidence from Twin and Family studies<br />
  • 58. Strengths<br /><ul><li>Evidence from twin & family studies as well as other research, supports this explanation
  • 59. This explanation is ethical because people are not blamed for their disorder
  • 60. Biological therapies can help to relieve the fear response</li></ul>Limitations<br /><ul><li>Biological explanations are reductionist, focusing only on the role of nature
  • 61. Biological explanations are deterministic, phobic responses are determined by our genes
  • 62. Biological therapies raise ethical concerns. Drugs can only suppress symptoms rather than cure the disorder and may cause addiction
  • 63. Psychological therapies can be just as effective as biological treatments</li></ul>Strengths and limitations of biological explanations<br />
  • 64. 3. Cognitive Explanations<br />The cognitive explanation suggests that<br /> anxiety disorders are caused by maladaptive thinking<br />Cognitive explanations can address some of the<br /> limitations of behavioural explanations, for<br /> instance why some people are more susceptible<br /> to acquiring anxiety disorders than others<br />Eysenck (1992) has suggested that people with anxiety disorders suffer from attentional bias <br />(the tendency to attend more than most people to threatening stimuli)<br />Explanations for an Anxiety Disorder – Phobias<br />
  • 65. Bradley et al (1999)<br />Tested the idea of attentional bias<br />Lab experiment<br />Exposed 14 GAD sufferers and 33 control ps to slides of happy or threatening faces<br />Results showed the GAD group responded with greater vigilance to all the faces<br />DiNardo<br />Tested whether excessive worry is a symptom of GAD<br />Quasi experiment<br />The frequency of the symptom “excessive worry” was measured and correlated with the % of the time the p experienced it<br />Excessive worry indicating attentional bias was more common in the GAD patients<br />Evidence for the Cognitive Explanation<br />
  • 66. Strengths<br />Is useful because it considers the role of thoughts and beliefs<br />Links to the behavioural explanation in assuming that anxiety is a learned response<br />Is supported by research evidence<br />Cognitive therapies are successful in treating anxiety disorders<br />Limitations<br />Reductionist because it fails to recognise the role of biology<br />Faulty cognition may be a consequence of the disorder rather than a cause<br />Strengths and limitations of cognitive explanations<br />
  • 67. Read p128-9 “Treatments for an anxiety disorder – phobias” in your textbook and briefly summarise the arguments.<br />Treatments for phobias<br />
  • 68. Behaviourists argue that if a phobia is learned behaviour then the treatment will consist of unlearning the behaviour<br />This is generally done by using classical conditioning. The phobic stimulus is paired with a stimulus which leads to a “no fear response”<br />Behavioural Treatments<br />
  • 69. Technique was developed by Joseph Wolpe to treat individuals suffering from phobias involving excessive fear of certain stimuli (e.g. Snakes and spiders)<br />Stage one;<br /> Provide clients with relaxation training in which they learn how to engage in deep muscle relaxation.<br /> Systematic Desensitisation<br />
  • 70. Stage two<br /> Clients construct a fear hierarchy with the assistance of their therapist.<br />A fear hierarchy consists of a list of situations/objects that produce fear in the client; starting with those that cause only a small amount of fear, and increasing to one that causes the most.<br />For example, if you have a phobia of spiders, you would start with a tiny spider 50 feet away, and increase the size whilst decreasing the distance.<br />Systematic Desensitisation contd.<br />
  • 71. Arachnophobia- a fear hierarchy<br />
  • 72. The patient imagines the least feared item and practices the relaxation technique until he/she feels no fear of it.<br />When the client can imagine the least feared items in the fear hierarchy staying relaxed and without experiencing fear, he/she moves onto the next item.<br />Eventually, the client can confront the most feared object or situation in the fear hierarchy without fear, at which point they are regarded as cured.<br />
  • 73. Can you make your own fear hierarchy?<br />
  • 74. McGrath – The treatment of a girl with a specific noise phobia.<br />Read the study p119<br />Make notes on the key evaluation points of the study<br />Key Study<br />McGrath<br />
  • 75. Strengths<br />+The basic ingredients of systematic desensitisation (muscle relaxation; fear hierarchy; association of phobic stimuli with relaxation responses) can easily be manipulated to test success.<br />+ The evidence supports its effectiveness. The study by McGrath and other research shows that individuals treated with systematic de-sensitisation improved more than those receiving no treatment (Choy et al.)<br />Limitations<br />- Only relevant to anxiety disorders. Even within the anxiety disorders, it can only be used when the stimuli producing a client’s anxious state can be identified. It wouldn’t be effective to use systematic de-sensitisation with someone suffering from GAD, because that involves excessive worrying about numerous situations<br />- Many of the phobias treated are relatively trivial. They don’t have the crippling effects on everyday life of other mental disorders such as depression or schizophrenia. However, this is arguable.<br />Evaluation of Behavioural Treatments<br />
  • 76. There are 3 main types of drugs used to treat phobias:<br /> <br />Tranquillisersare very effective at relieving anxiety, but can be addictive after only four weeks regular use. These drugs should be only used for short periods, perhaps to help during a crisis. They should not be used for longer-term treatment of anxiety.<br /> <br />Antidepressants can help to relieve anxiety as well as the depression for which they are usually prescribed. Some even seem to have a particular effect on individual types of anxiety. Can take 2 to 4 weeks to work and some can cause nausea, drowsiness, dizziness, dry mouth and constipation.<br />Beta blockers are usually used to treat high blood pressure.  In low doses, they control the physical shaking caused by anxiety Most commonly used for social phobia.<br />Biological Treatments for Phobias<br />
