Exam questions Flashcards
From the study by Dement and Kleitman identify one reason for using EEG to measure brain activity
which stage of sleep the participants are in REm/nREM
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
Describe one assumption of the social approach (2)
Behavior cognition and emotion can be influenced by groups or social contexts
Outline one other real-world application based on the finding from the Milgram’s study
65% went to the end 450V under authority figure. — People follow orders from authority figures. When crime happens find authority figure to stop the crime from happening.
Helped us find understand why WW2 may have happened (destructive obedience)
Strengths of Dement and Kleitmen (8)
Standardized - doorbell (every participant experienced the same thing)
High reliability - EEG quantitative data, is not affected by experimenters subjective view: both quantitative data and qualitative data is collected
Demand characters minimized: did not tell participants about EEG patterns
Operationalised : meaning of dreams
Weakness of Dement & Kleitmen (ethics) (6)
Low generalizability: small sample
Ethics: participant WD deception misled about REM and nREM
Low ecological validity: sleeping in a lab / no caffeine / alchohol
Eye movements (8)
- Vertical : throwing basketball - looking down to see one
- Horizontal : watching people throw tomatoes at each other
- Little movement: driving / looking at something at a distance
- Mixed: giving a speech
Dream recall when woke up in REM %
79.6%
Time guessing Dement and Kleitmen (2)
88% - 5 mins 78 - 15 mins
Hasset et al. Sample (3)
82 Rhesus monkeys
21 male
61 female
type of sampling Hasset et al
Opportunity
Type of experiment Hasset et al
Field experiment
Measures designed Hasset et al
independent measures design
How many toys Hasset et al (2)
6 ‘male’ toys - wheeled toys
7 ‘female’ toys - plushies
Results of Hasset et al (2)
males prefer male toys
female don’t really have preference - played with female toys more than males
Strengths of Hasset et al + ethics (10)
Inter rater validity - 2 observers came to o consensus each time
Counterbalancing - placement of the toys changed each time
Behavioral categories clearly defined: sitting, dragging, sniffing etc.
standardized: trials/ time
Ethics:
Ethically taken care of
watched on cameras - no disturbance? controlled demand characteristics
Unethical to grow children away from society - did the experiment on monkeys
How long did the trials last for? Hasset et al (2)
7 trials , 25 mins each
Weakness of Hasset et al (2)
Methodological differences: hey did a study on children beforehand - study was conducted differently: different toys / children did individually while monkeys did in groups
—> hard to make it comparable
Conclusion of Hasset et al (2)
Females are more variable in their toy preferences
support biological explanation for toy preferences—> in absence of socialization as well
Nature vs Nurture in Holzel et al (1)
the study showed that nurture through MBSR can affect structures and processes.
