Q

What are some ethical issues with Watson and Raynor’s 1920 study?

A

Watson intended to de condition little Albert, but his mother left before it was possible

It is now thought that little Albert was not as easy to condition as thought, and Watson “topped up” the conditioning by using the clanging noise

Q

What was the procedure of Mower’s 1960 study?

A

Rats were classically conditioned to fear the sound of a buzzer as it was associated with an electric shock

They were then placed in a cage with a barrier they could jump to avoid the electric shock, if the buzzer sounded

The rats started jumping the barrier whenever they heard the buzzer, suggesting this jumping behaviour had been negatively reinforced by the reduction of fear

Q

What was the procedure of Bandura and Rosenthal’s 1966 study on observational learning of fear?

A

Participants watched another person (confederate) ‘receive’ electric shocks when a buzzer sounded, after a few times the participant started to show emotional signs of fear at the buzzer, despite never being shocked themselves.

Q

What is important background knowledge required for Cook and Mineka’s study?

A

Monkeys in the wild generally show strong fear to snakes, but lab reared monkeys do not, which suggests that monkeys are NOT innately afraid of snakes

Q

What was the method of Cook and Mineka’s study?

A

None of the monkeys had seen snakes or rabbits before

The monkeys were shown a picture of a snake and a video of mother acting fearfully, then it was measured how long it took for the baby monkeys to show fear of the snake

This was then repeated for the pairing of the rabbit and the mothers fear.

Q

How many therapy sessions did each group receive in Gilroy’s (2000) study?

A

Three 45-minute sessions

28
Q

How were phobic symptoms measured in Gilroy’s (2000) study?

A

Through questionnaires and a behavioural test of how close participants could get to a spider

29
Q

What were the results of Gilroy’s (2000) study?

A

The computer aided exposure was an effective treatment and comparable to live exposure treatment

Both exposure treatments were better than the placebo

33 months later, 42/45 patients were followed up, and the improvements after exposure were maintained almost 3 years later

30
Q

When were patients’ fear levels measured in Gilroy’s (2000) study?

A

Before treatments, after treatments and 3 months later

31
Q

What study looked at the effect of systematic desensitisation on technophobia?

A

Bronson and Thorpe

32
Q

How many patients were there in Bronson and Thorpe’s study 1?

A

8 (6 female 2 male)

33
Q

What was the conclusion of Bronson and Thorpe’s first study?

A

Systematic desensitisation can significantly reduce anxiety of technology (technophobia)

34
Q

What was the conclusion of Bronson and Thorpe’s second study?

A

Even one session of systematic desensitisation can have a massive impact on reducing technophobia

35
Q

How many weeks of systematic desensitisation did participants receive in Bronson and Thorpe’s (2006) study? (Study 1)

A

10 weeks

36
Q

What evidence is there for the effectiveness of flooding?

A

Wolpe (1960) conducted a case study of a girl with a fear of driving who was driven around for 4 hours until she overcame her fear

Teasdale (1977) reviewed evidence for flooding to find it was mixed, for flooding to work it must last a long time (at least 30 minutes for snake phobias)

Barlow (2002) found that if a patient is willing to undergo flooding it is just as effective as systematic desensitisation

37
Q

Who created the ABC model of depression?

A

Albert Ellis

38
Q

Who created the cognitive approach to depression?

A

Aaron Beck

39
Q

Which study provides evidence for memory biases in depression?

A

Clark and Teasdale (1985)

40
Q

What was the procedure of Clark and Teasdale’s 1985 study?

A

They tested depressed patients for their memories of events that had happened in their lives, in the morning and in the evening

41
Q

What were the results of Clark and Teasdale’s study?

A

Those who experienced worse depression in the morning gave more negative memories in the morning and vice versa.

42
Q

What was the conclusion of Clark and Teasdale’s study?

A

Depressed mood causes biases in memory towards recalling negative events which then worsen depression - supports the view that emotions are linked to the way we think

43
Q

Which longitudinal study looked at whether negative thinking caused depression or vice versa?

A

Lewisohn (2001)

44
Q

What was the method of lewisohn’s study?

A

Lewisohn measured negative attitudes in adolescents, none of which were depressed. He then followed up the sample a year later and assessed if they were suffering from depression and whether they had experienced any unpleasant life events.

45
Q

What were the results of Lewisohn’s study?

A

Those who experienced negative life events AND had negative attitudes were mist likely to be suffering from depression

46
Q

What was the conclusion of Lewisohn’s (2001) study?

A

Negative thoughts are a cause if depression

47
Q

Which study looked at the effectiveness of CBT and antidepressants in women with post natal depression?

A

Appleby (1997)

48
Q

How many women were in Appleby’s 1997 study?

A

87 women from Manchester

49
Q

What were the three categories the 87 women were randomly allocated to in Appleby’s 1997 study?

A

Antidepressants (SSRI)
CBT
Drug Placebo

50
Q

How long was each treatment given for in Appleby’s 1997 study?

A

12 weeks

51
Q

How was the effectiveness of treatment measured in Appleby’s study?

A

Self report, and observation of depression symptoms

The study was double blind, as patients did no know if they received SSRI or placebo, and blind as observers did not know if patients received CBT, SSRIs or placebo

52
Q

What were the results of Appleby’s 1997 study?

A

CBT was just as effective at reducing symptoms of depression as SSRIs, and both were more effective than the placebo

53
Q

What evaluation points could be made about Appleby’s study?

A

:) - a well designed study using patients in a typical NHS set up

:( a no follow up to see if patients relapsed after treatment

54
Q

What study looked at the long term effectiveness of CBT compared to medication?

A

Hollon et al (2005)

55
Q

How many participants were there in Hollon et al’s study?

A

104

56
Q

What was monitored in Hollon et al’s study?

A

Rates of relapse over 12 months

57
Q

What was relapse defined as in Hollon et al’s study?

A

Depression symptoms for 2 weeks

58
Q

What were the results of Hollon et al’s study?

A

Those treated with CBT had lower rates of relapse than those treated with SSRIs

59
Q

What did polak et al (2012) look at?

A

A case study of a 65 year old man who suffered brain damage to the basal ganglia during a heart attack and showed compulsive whistling from age 42

60
Q

What is deep brain stimulation?

A

Inserting electrodes into the basal ganglia to to alter the communication between the basal ganglia and the orbito frontal cortex

61

A

Nestadt (2010)

62
