Q

Explain classical conditioning

A

-2 stimuli repeatedly used together causing one to associate with another -unconditioned stimulus triggers unconditioned response -neutral stimuli paired with UCS = leads to CS -overtime = conditioned response

Q

How did Skinner use the skinner box to operantly condition rats?

A

everytime a rat pressed the lever, a food pellet fell into the food dispenser (positive reinforcement), quickly learned to go straight to the lever after a few times of being put in the box
rat was also subjected to an uncomfortable electrical current, as they moved around the cage, the rat hit the lever, which immediately switched off the electrical current (negative reinforcement) rats quickly learned to go straight to the lever after a few times of being put in the box.

Q

Evaluate a strength of Bandura et al.’s study

A

-clever experimental design, reduced impact of EV’s = enhanced internal validity -matched for aggression before -control group -one at time: controlled conformality effects

46
Q

Evaluate a weakness of Bandura et al.’s study

A

-artificial environment -lacks external validity -can’t be generalized to outside the lab

47
Q

Evaluate an application of Bandura et al.’s study

A

-learning aggressive behavior (especially boys) -adult role models (parents) -psychologists + social workers = better understanding of risks to children’s development by violent parents -important implications of policy around custody and parental contact

48
Q

What were the two variations of Bandura’s study?

A

effect of media exposure
effect of vicarious reinforcement

49
Q

How did the findings of the film-mediated aggressive models variation differ to the original results?

A

-all 3 groups (live, filmed realistic, cartoon) had increased aggression

50
Q

How did the findings of the influence of model’s reinforcement variation differ to the original results?

A

model punished = group significantly less aggressive
-however introducing promise of reward if aggression was shown increased aggression significantly for all groups

51
Q

What is the difference between a fear and a phobia?

A

fear = sensible phobia = irrational and life limiting

52
Q

What is the 2 process model of phobias?

A

explains both the acquisition and maintenance of phobias -acquired by classical conditioning -maintained by operant conditioning

53
Q

How could phobias be maintained by classical conditioning?

A

-association needs to be paired often unless strong enough first time -confirmed by Watson and Rayners’ study of Little Albert

54
Q

How are phobias maintained by operant conditioning?

A

Negative reinforcement, by avoiding the phobia you are avoiding the negative feelings of being scared

55
Q

How are phobias maintained by social learning theory?

A

-Lieb et al. (2000) -children of parents with a phobia were more likely to have same phobia -someone else modelling phobia = learnt

56
Q

What are strengths of using classical conditioning to explain phobias?

A

can account for acquisition -Watson + Rayner experimented, others have replicated: found that you can be conditioned to fear something (using careful controls)

57
Q

What are strengths of using operant conditioning to explain phobias?

A

shown to maintain phobias -Skinner: shows that maintenance of behavior can be controlled through reinforcement and punishment

58
Q

What are weaknesses of using classical conditioning to explain how phobias are developed?

A

-animals rather than humans used in the basis research on classical conditioning (pavlov): different brain structures
-can’t generalize particularly with anxiety and fear (personal to each person)
-experimentation relied on careful controls, limiting ecological validity of results

59
Q

What are weaknesses of using operant conditioning to explain how phobias are developed?

A

-phobias arise in real life taking into account environment, surroundings, etc… -all factors can’t be carefully controlled

60
Q

What are the 2 types of treatment for phobias?

A

systematic desensitization -flooding

61
Q

What are the stages of systematic desensitization?

A

1: FUNCTIONAL ANALYSIS: careful questioning to discover nature of anxiety 2: CONSTRUCTING HIERARCHY: provoking situations from least to most fearful 3: RELAXING TRAINING: acts as desensitization, therapist teaches client to relax as deeply as possible 4: GRADUAL EXPOSURE: systematic component

62
Q

Give strengths of systematic desensitization.

A

-ethical (gradual, individuals fully involved)
-studies show success -> clients receiving SD for spider phobia compared with control group = SD group less fearful after 33 months

63
Q

Give 3 weaknesses of systematic desensitization.

A

-not everyone can learn to relax -operant conditioning principles + cognitive processes impact (can’t be fully explained by classical conditioning) -SD may not always be appropriate (e.g. phobia linked to history of trauma)

64
Q

What is flooding?

A

exposing patients to their phobic stimulus straight away -total immersion

65
Q

Give 2 strengths of flooding.

A

cost effective and as effective as alternatives -clients free from symptoms sooner (quicker)

66
Q

Give 2 weaknesses of flooding.

A

may not be effective for all phobias -ethical issues: unpleasant experience, traumatic

67
Q

What is our classic study?

A

Watson and Rayner (1920)

68
Q

What was the aim of Watson & Rayner?

A

demonstrate that simple emotional responses such as fear can be acquired through a process of classical conditioning

69
Q

What was the procedure of the classic study (Watson & Rayner: Little Albert)?

A

-healthy boy, 9 months old: Little Albert -baseline emotional responses to range of objects tested
-5 sessions across 2 weeks -
white rat presented, loud noise struck behind head when he reached to touch

70
Q

What were the findings of the classic study (Watson & Rayner: Little Albert)?

A

-at baseline testing = no fear but startled by noise -session 1: cried to noise -session 2+3: more cautious to rat, cry&crawl away -only reacted to white fury objects with fear (cried) -sessions 4 + 5: fear to white fury objects remained

71
Q

Evaluate strengths of Watson and Rayners study.

A

good experimental controls = reduced impact of extraneous variables and enhanced internal validity -Little Albert carefully chosen (emotional stability) -well controlled room to prevent other stimuli -baseline responses checked

72
Q

Evaluate an opposing argument of Watson and Rayners study.

A

rsome aspects not controlled -e.g. rat was suddenly pushed towards him whereas rattle or ball were placed on floor, movements may have triggered responses rather than animals themselves

73
Q

Evaluate weaknesses of Watson and Rayners study.

A

-only uses 1 ppt = may not be representative of whole population -not certain of Albert’s identity so no way of knowing how representative of a child he was -results may be affected by ppt variables

74
Q

Evaluate an application of Watson and Rayners study.

A

understanding acquisition of phobias -development of effective therapies -importance in shaping clinical practice

75
Q

What was the contemporary study?

A

Becker et al. (2002) Eating behaviors following prolonged exposure to TV

76
Q

What were the aims of Becker et al.’s study?

A

investigate social learning in context of eating behaviors -investigate impact of western attitudes on eating behaviors -see what effect ideas communicated through TV has on body satisfaction + eating disorders

77
Q

What was the procedure of Becker et al.’s study?

A

-independent measures design, first sample of 63 in 1995, second sample of 65 different girls in 1998
-1st group of teenage girls questioned before TV’s introduced in Fiji, 2nd group questioned 3 years later
-standard questionnaire (EAT-26) and semi-structured interview (quantitative + qualitative)
-height & weight also measured

78
Q

What were the findings of Becker et al.’s study?

A

eat 26 score from 1st sample = 12.7% above 20
from 2nd sample = 29.2% above 20
(above 20 signifies unhealthy eating habits)
rise in self induced vomiting
74% said they felt their body was ‘too large’, 69% had been on a diet

79
Q

What were the conclusions of Becker et al.’s study?

A

women in western TV programs became role models = desire thinner bodies -rise in eating disorders + decline in body image

80
Q

Evaluate strengths of Becker et al.’s study.

A

construct validity, semi sctectired interviews allowed them to expand on questionnaire answers giving further insight
reliable measurements -studies show good reliability of eat-26 = good internal reliability -differences likely to be due to real changes over time

81
Q

Evaluate an opposing argument of Becker et al.’s study.

A

-although reliability was good, issues with validity -e.g. EAT-26 isnt an official eating disorder diagnosis

82
Q

Evaluate weaknesses of Becker et al.’s study.

A

-poor generalisibility -unrepresentative sample (only in Fiji) -Fiji traditionally have distinctive attitudes towards body types (high BMI = attractive)

83
Q

Evaluate an application of Becker et al.’s study.

A

treating eating disorders -applied to TV programs + advertising -learnt through modelling so unlearned in same way

84
Q

what is the aim of our learning practical?

A

to investigate if there is a difference in politeness between genders

85
Q

what is the background question of our learning practical?

A

social learning theory we learn gender appropriate behaviours from the people around us. role models show us how to behave and is reinforced through rewards and punishment

86
Q

what are the variables we measured in our learning practical?

A

politeness
gender

87
Q

what are the operationalised variables for our learning practical?

A

politeness —> whether a person says thank you at the end of a lesson or not
gender —> person’s appearance

88
Q

what is the research hypothesis of our learning practical?

A

there will be a significant difference in politeness (number of students who say thank you at the end of a lesson) based on gender (mae vs female)

89
Q

what is our sample in our learning practical?

A

opportunity sample
sixth form students (16 - 18)
Chose a class with a relatively 50/50 split of genders so as not to make differences appear greater or smaller than they actually are (alpha biased)

90
Q

what extraneous variables may influence our learning practical?

A

if teacher/student needs to leave quickly
if teacher has told off the class previously
personality of student (shy or outgoing)

91
Q

what was the procedure of our learning practical?

A

Naturalistic covert non-participant observation
Using a tally chart we made a note of how many boys versus how many girls said thank you and how many boys vs how many girls didn’t when leaving the classroom after class
We also noted down elements of qualitative data for example whether they said ‘have a good day’ after saying thank you or if they just said ‘cheers’ rather than thank you

92
Q

what was the results of our learning practical?

A

for a chi-squared test, a two tailed hypothesis, df=1 and p<0.05, the critical value is 3.84. our observed value was less than the critical value, the results are not significant. consequently, we reject the research hypothesis and accept the null hypothesis. as such, there is no difference in politeness based on gender

93
Q

what did we find through thematic analysis of our learning practical?

A

girls are more likely to say thank you formally, with eye contact, whilst still in the room, in a clear voice and do so even if in a group.
“thank you sir!”
boys are more likely to say thank you informally, without eye contact, whilst waking out the door, mumble and have one person say thank you for the whole group.
“cheers”

94
Q

what did we find through quantitative analysis of our learning practical?

A

On average, 85% of the girls in the class were classed as polite as opposed to 42% of the boys in the class.

95
Q

describe the construct validity of our learning practical

A

mixed
- if someone says thank you that is polite (face validity)
- could be impolite but self interested (its their teacher. may not act the same way with someone they dont need something from)
- no ‘thanks’ may mean they are impolite or could just be shy or in a rush

96
Q

describe the ecological validity of our learning practical

A
  • real life setting (naturalisitic), non-participant of covert observation so no demand characteristics so no social desirability bias
  • this is real life, relaistic politeness behavior, so results are likely to transfer
97
Q

describe the population validity of our learning practical

A
  • target pop = all normal adults
  • sample = 16-17 year olds
  • good pv –> you are who you are by 17 so if theyre not polite by now they probabliy wont ever be
  • but this is more true for girls than boys. boys more concerned with status at 17 less likely to say thanks than men in their 30s
98
Q

describe objectivity of our learning practical

A

very little opinion involeved injuding gender or whether they said thank you or cheers etc.
- qualitiative data was objective. we said boys purposely lowered their voice. but this is just our opinion, their voices might just be lower

99
Q

describe the reliability of our learning practical

A
  • inter-rater reliability is high (M vs F), polite vs impolite is very clear and objective)
  • not too fast paced, 2 people in same class would see the same thing
  • external reliability (test re-test) is low.
    observation on mon P1 would be worse than fri P5 for example
100
Q

what is our learning theories key question?

A

Is the media to blame for anorexia?

101
Q

Describe the issue (anorexia)

A

Anorexia nervosa is a mental health disorder characterized by a phobia of weight gain causing effects such as low BMI and fatigue from missing meals. Anorexia effects 0.3% of the UK 90% of which are teenage girls. This disorder causes extreme damage to the bodies of those who suffer, 10% of hospitalised cases die either of starvation or suicide it can also lead to the breakdown of marriages or families due to the stress.

102
Q

The media is to blame: support from Becker (key question)

A

Becker aimed to investigate the effect of Western media on eating behaviours. She used the 826 survey on 63 young Fiji and women in 1995 before TV was introduced to Fiji, then again on 65 different adolescence in 1998. 12.7% of the girls before TV had worrying attitude towards eating (signified by a score over 20) compared to 29.2% after TV. There was also reports of higher levels of self-induced vomiting as a form of weight control. These behaviours are unusual for Fijian Culture as they value robust body types with little exercise, arguably showing that the Western media did have a harmful effect on the girls eating behaviors.

103
Q

The media is to blame: social learning theory (key question)

A

Bandura’s social learning theory suggests people learn through observation and imitation of role models, with this behavior more likely when the model is the same gender as the imitator and when the behavior is rewarded (called vicarious reinforcement). Beauty standards in the industrialized west emphasizes that thin women are more beautiful and successful. This could explain the gender difference in the prevalence of anorexia as young women will try to imitate the women in the media’s looks.

104
Q

The media is not to blame: methological flaws with Becker (key question)

A

The eat26 survey is not a clinical eating disorder diagnosis it just suggests unhealthy eating attitudes. It can be argued that it’s unethical to make the girls believe they may have had a medical disorder instead of just unhealthy eating. Similarly 8 out of 63 girls in the first sample had suggested unhealthy eating before TV so there must be another reason than the media. Correlating a rise of self-induced vomiting with eating disorders is a Western view so may not be a symptom of disordered eating in Fiji highlighting the ethnocentric nature of the study.

105
Q

The media is not to blame: Bandura’s issues of generalisability

A

Bandura’s social learning theory study generalises from children to adults and adults may not imitate behaviour in the same way or prevalence of children. The study also has low ecological validity as the aggressive behaviour that the children were exposed to is not reflective of the behavior they would be exposed to in real life (hitting an inflatable clown and calling it names). Cumberbatch 1990 also argued that the comedic novelty nature of the doll made the children five times as likely to imitate the behavior. This study was also a short-term study whereas anorexia is a lifetime illness so it can be argued that these findings are not generalizable

106
Q

what is our conclusion for our key question?

A

the media can have negative effects (the rise in scores in Becker’s study, evidence from SLT showing they can learn these behaviours) However they’re also must be other explanations for it as some girls already displayed negative attitudes towards eating in Fiji before the introduction of Western TV

107
Q

The role of learning in Child Development: Beverly Fagot (1978)

A

Observational study of toddlers playing at home with their parents and noted punishments and praise given. Found that boys were reinforced for playing with gender typical toys and punished for playing with dolls so lending support to the idea that gender role behaviour is Learned From the child’s environment. However, The study was carried out in the 1970s so we can argue that gender socialization has changed
