Q

Two ethical guidelines are debriefing and informed consent. Suggest how ethical. issues raised in the Piliavin et al. study (subway Samaritans) relate to these two ethical guidelines (4)

Debriefing:
Participants did not know they were part of the study, did not have the aims explained or time for questions — psychological harm

Informed consent:
No one knew this was going to happened as consent did not happen —> exposed to a situation which may have cause psychological harm

Operationalised : meaning of dreams

Q

Sampling in Holzel et al (6)

A

opportunity sampling
University of massachusetts’s who already signed up for the MBSR course
16 experimental
17 control
aged 25 -55

22
Q

Measures designed Holzel et al

A

Independent measures design

23
Q

Procedure Holzel et al (4)

A

Completed questionnaire before & after the intervention
MRI scans before & after the intervention
Body scan, mindful yoga, meditation
Homework 45 min video

24
Q

Results of Holzel et al (4)

A

Grey matter density in the brain - hippocampus : positive change in the experimental group no change for control group
No significant correlation between time spent on body scans, yoga , mediation
Increased mindfulness scores

25
Strengths of Holzel et al & ethics (7)
longitudinal study —> high external validity Standardization —> fixed number of excersies - fixed duration —> highly replicable - high reliability Ethics: right to withdraw - 2 participants withdrew made sure all were safe to do MRI scans
26
Weakness of Holzel et al (4)
Low generalizability —> already enrolled to MBSR Lack of correlation with the homework —> low internal validity
27
Results of Andrade (2)
Control group recall - 7.1 Experimental group recall - 7.8
28
Individual and Situational explanation of Andrade (2)
Individual - participants may have used a similar strategy before or have a personality turpentine that requires stimulation when processing information SItuational - process of cooling could have caused the improvement in recall
29
Strengths of Andrade (8)
Standardized procedure —> easy to replicate —> reliability —> likely to daydream as they could be bored and tired of the day —> thinking about going home Operlationalised: doodling sheets —> reduced individual differences Generalizability —> 18 - 55 years High ecological validity —> real life —> classroom Quantitative data — amount memorized
30
Weaknesses of Andrade’s study (5)
Ceiling effect —> test was easy should put more names Participants were part of psychology panel —> may have suspected something —> demand characteristics —> reduced validity no measure of day dreaming
31
Ethics in Andrade (3)
1. debriefing well done 2. Asking them to recall may have caused psychological harm 3. deception
32
Sample in Andrade (6)
Psychology Panel of a university 18 - 55 20 participants 10 in experimental 10 in control asked to try after unrelated study for 5 mins
33
Procedure in Andrade (6)
asked to stay after unrelated study for 5 mins given A4 paper (controlled - lined , experiment - shapes to color in) listened to 2.5 min recording 227 wpm 8 party attenders , 3 people , 1 cat , 8 places after 1 minute (debriefed during this time - asked anyone suspected) asked for names / places —> counterbalanced
34
Baron - Cohen et al aim (2)
investigating theory of mind —> ability to attribute ones mental states or another person, which is how we make sense of or predict another person’s behavior —> in other words —> ‘empathy’
35
Strengths of Baron-Cohen (4)
High internal validity —> changes made to the eyes test —> 4 options, equal female and male pairs , glossary Standardized - image same size, black and white , 1 correct answers —> 8 judges who decided on the emotions
36
Weakness of Baron-Cohen (3) & ethics
Low ecological validity - not applicable to everyday life- we don’t look at just eyes Low generalizability- ASD only 15 Ethics: If they could not guess the emotion they may feel embarrassment —> psychological harm
37
Sample of Baron-Cohen (3)
Opportunity — for 3 of the groups (adult - library users , students - cambridge university) Random selected IQ ASD - magazine volunteer sampling (15)
38
Results of Baron-Cohen (3)
ASD group did significantly worse normal adults inverse correlation to ones who have ASD Women got higher scores than males - not that significant though
39
Procedure of Baron-Cohen (2)
individually in room - everyone take AQ test “then take the reading the mind in the eyes “ test
40
Hypothesis of Pozzulo (4)
1. Good as adults for cartoon (identification) 2. worse than adults for cartoon target absent (rejection) 3. worse than adults for human target 4. worse than adults for human target absent (rejection)
41
Experiment - Pozzulo
Lab
42
Procedure of Pozzulo (5)
Human : 2 videos - 6 seconds Cartoon : 2 videos - 6 seconds (dora & diego) tested individually filler questions asked before the line up black silhouette box if target was absent
43
Sampling of Pozzulo
59 children 4-7 Private schools - eastern ontario 53 adults 17-30 Psychology participant pool - eastern ontario Both: opportunity sampling
44
Measures design Pozzulo
independent
45
Results of Pozzulo
All hypothesis proved correct
46
Conclusion Pozzulo (2)
Errors in the target - absent lineup result from social factors not cognitive factors —> for children
47
Ethics Pozzulo (2)
Deception children knew they had the right to withdraw no psychological or physical harm was done
48
Strengths Pozzulo (4)
High standardization along with controls —> experiment with children and adults as identical as possible quantitative data —> objective
49
