ALL STUDIES (SL/HL) INCLUDED
Newcomer et al. (1999)
**USE FOR: Biological principle (biology correlates with behaviour)
Aim: Find role of the stress hormone cortisol on verbal declarative memory.
Group 1: High dose condition
Group 2: Low dose condition
Group 3: Placebo tablets (control)
- Listened to a prose paragraph
- Had to recall it (verbal declarative memory)
Results: Group 1 showed the worst performance (cortisol increase can have a negative effect on memory)
Rosenweig, Bennett, and Diamond (1972)
**USE FOR Biological principle (animal research)
Aim: Study role of environmental factors on brain plasticity using rats
Group 1: Enriched environment
Group 2: Deprived environment
Results: Rats in Group 1 showed a thicker layer of neurons in their cortex compared to deprived group (brain grows the more that neurons are stimulated)
Bouchard et al. (1990)
**USE FOR: Biological principle (behaviour is genetically based); extent to which genetics influence behaviour
aka Minnesota Twin Study
Aim: Investigate relative roles in genes in IQ
MZ reared Apart
MZ reared Together
Results: MZT had concordance rate of IQ of 86%. MZA had concordance rate of IQ of 76% (there is a link between genetic inheritance and intelligence, but does not rule out the role of environment)
Darley and Gross (1983)
**USE FOR: Cognitive principle (mental processes guide behaviour); Evaluate schema theory; stereotypes effect on behaviour
Aim: Investigate schema theory
- Showed a girl in a poor environment, then a wealthy environment.
- Asked participants how well she would do in an intelligence test
Results: Most participants figured the “wealthy” girl would do better than the “poor” girl (human beings actively process information based on salient details to make an impression that may or may not be true)
Loftus and Palmer (1974)
**USE FOR: Cognitive principle (mind can be studied scientifically); reliability in cognitive processes (reconstructive memory)
Aim: Test reconstructive memory in relation to eyewitness testimony
- Showed a picture of a car crash to participants
- Asked to estimate how fast the car was going when it “smashed”/”hit”/”bumped” the other car
Results: The change of word ultimately caused different results in estimated speed (significant difference)
Bartlett (1932)
**USE FOR: Cognitive principle (influenced by social and cultural factors); Evaluate schema theory; emic concept
Aim: Investigate differences in interpretation of a story
- Asked British participants to read an unfamiliar Native American story
- British participants were then asked to reproduce it
Results: The participants changed details of t story to fit with their own cultural schemas
Scoville and Milner (1957)
**USE FOR: Multi-store model of memory; how biological factors may affect a cognitive process; localization of the brain
- Choice of interviewer
- Extent of training of interviewer
aka H.M. Case Study - H.M. fell off his bike at the age of 7; constant epileptic seizures caused life to be difficult.
- Scoville performed experimental surgery to try and end seizures, which was successful, but H.M. suffered from amnesia for the rest of his life
- H.M. had severe damage to the hippocampus (shown in MRI scans), and was unable to store new memories.
- In a more complex sense, he could store new procedural memories (implicit memory) but was unable to store new explicit memories (semantic/episodic).
- He could carry on normal conversations, but would forget the meaning of the conversation immediately after.
- Shows that hippocampus is vital to making new memories.
- Also shows that the memory system contains different systems within itself.
Rogoff and Waddel (1982)
**USE FOR: how social/cultural factors affect one cognitive process
Aim: Investigate culture and memory
- Constructed a miniature model of a Mayan village
- Researcher selected 20 miniature objects from 80 and put them in the model.
- Objects were taken out and replaced among the other 60 objects.
- Children (Mayan and American) were asked to reconstruct the scene they had been shown.
Results: Mayan children did slightly better because the scene meant more to them than it did to the American children.
Brown and Kulik (1977)
**USE FOR: how emotion may affect a cognitive process (theory)
Aim: Investigate flashbulb memory (vivid memory due to shock)
- 80 participants were asked to recall circumstances where they learned of shocking events
Results: Participants had very vivid memories of what, where, when, and how. Used assassination of John F. Kennedy, or death of a loved one as a base (to find what was correct).
- Shows it is more likely for unexpected/personally relevant events
- May be caused by the physiological emotional arousal from learning of the event
- Emotion could have influence the reconstructed memory; flashbulb memory may not be entirely accurate
Davidson et al. (2004)
**USE FOR: interaction between cognitive/physiology in terms of behaviour
Aim: Investigate whether meditation can change brain activity
Experimental: 8 monks (study meditation often)
Control: 10 students (1 wk of training)
- Asked to meditate on “unconditional compassion”
- Control took a training session (where they were asked to open feelings of compassion)
- Control was then asked to feel compassion without thinking of someone
- Monks’ brains (through EEG scans) showed greater activation as well as better organization and coordination of gamma waves
Fessler et al. (2005)
**USE FOR: evolutionary explanation of behaviour
Aim: Investigate if disgust sensitivity in the first trimester of pregnancy was elevated as predicted
- A survey was completed by 691 women online, with the mean age of the participants being 28.1 yrs
- Indicated current level of nausea and answered questions to test disgust sensitivity in food, animals, body products, dead animals, hygiene, and toilets
Results: Disgust was particularly elevated in food. Known that food-borne illnesses are particularly dangerous in first trimester, which indicates possibly why disgust of food is so much higher at that point of pregnancy.
Hamilton (1963)
**USE FOR: explaining altruism in humans
aka Kin Selection Theory
- Based on idea that organisms are more likely to aid their own kin rather than non-kin
- Contribute to survival of own genes (selfish gene theory by Dawkins 1989)
Simmons et al. (1977)
**USE FOR: kin selection theory
Aim: Investigate likelihood of close relatives in becoming kidney donors
Results: 86% of parents said yes; 47% of siblings said yes (the closer the potential donor was to the relative, the more likely they were to become donors, taking into account gender, same sex, etc.)
**NOTE Does not explain how there were people who said no to becoming a donor
Batson et al. (1981) THEORY
**USE FOR: explaining altruism in humans
aka Empathy-Altruism Theory
- Suggests that some actions truly are altruistic
- Based on motives of an individual (empathic conern/personal distress or egoism)
Batson et al. (1981) EXPERIMENT
**USE FOR: empathy-altruism theory
Aim: Investigate motives to help when there is an opportunity to escape
Condition 1: High empathy/Difficult escape
Condition 2: High empathy/Easy escape
Condition 3: Low empathy/Difficult escape
Condition 4: Low empathy/Easy escape
Easy escape: Replace Elaine/Fill in questionnaire
Difficult escape: Replace Elaine/Watch remaining trials
- Participants watched a tester (Elaine) answering questions wrong and getting electric shocks.
- Asked if they wished to take her place.
Results: Those in HE/HD condition were more likely to replace Elaine. Those in LE condition were less likely.
Latané and Darley (1970) THEORY
**USE FOR: factors in influencing bystanderism
aka Theory of the unresponsive behaviour
- Suggests that the presence/feeling of witnesses to an event will decrease likelihood that an individual will intervene.
Due to psychological processes like:
- Diffusion of responsibility
- Informational social influence (pluralistic ignorance)
- Evaluation apprehension
Latané and Darley (1968)
**USE FOR: bystanderism
Aim: Investigate if the number of witnesses of an emergency influences people’s helping in an emergency situation
Participants were told that discussion was between:
Condition 1: 1 other person
Condition 2: 3 other people
Condition 3: 6 other people
- 72 students (59 female, 13 male) were asked to discuss personal problems new colleges could have in an urban area.
- Were told that the discussion took place via an intercom to protect the anonymity of participants.
- A confederate staged a seizure.
Researchers looked at the time it took for participants to contact the experimenter
Results: 85% in Condition 1 reported the seizure. Only 62% in Condition 3 reported the seizure and were slower to help.
Pilliavin et al. (1969) THEORY
**USE FOR: bystanderism
Cost reward model of helping
Suggests that both cognitive (cost-benefit analysis) and emotional factors (unpleasant emotional arousal) determine whether bystanders to an emergency will intervene.
Focus on egoistic motivation to escape an unpleasant emotional state (empathy-altruism model).
Note that egoistic motivation is not always the reason for help however.
Pilliavin et al. (1969) EXPERIMENT
**USE FOR: bystanderism
aka Subway Samaritan
Aim: Investigate the effect of various variables on helping behaviour.
Condition 1: confederate was “drunk” (black/white)
Condition 2: confederate was “ill” (black/white)
- Performed a scenario with each condition, where the confederate collapsed on the floor.
- Participants were subway travellers who observed the scenario.
- If no one helped after 70 seconds, a model helper intervened.
Results: The person who was ill was more likely to receive help. In 60% of trials, more than one person offered assistance.
Found that people look at:
- costs of helping
- costs of not helping
- rewards of helping
- rewards of not helping
LeDoux (1999)
**USE FOR: cognitive/biological factors in emotion
aka Theory of the emotional brain
Based on idea that humans’ emotional reactions are flexible due to evolution. Learning to detect and respond to danger is important for survival. The evolved “emotional feeling” helps evaluate the level of danger before a response. (fear)
Short route: Amygdala reacts immediately to sensory input and activates response systems. Useful in case of immediate danger.
Long route: Sensory input goes via the sensory cortex to the hippocampus. Involves evaluation of stimulus to consider an appropriate response (cognitive appraisal)
Lazarus (1975)
**USE FOR: cognitive/biological factors in emotion
aka Appraisal theory
Suggests that cognitive factors can modulate stress responses (physiological/psychological reactions involved in experience)
Basically an evaluation of a situation.
Speisman et al. (1964)
**USE FOR: appraisal theory
Aim: Investigate the extent to which manipulation of cognitive appraisal could influence emotional experience.
Condition 1: Trauma (emphasis on mutilation/pain)
Condition 2: Intellectual (anthropological interpretation)
Condition 3: Denial (willing and happy adolescents)
- Participants saw anxiety-evoking films (ex. circumcision of aboriginal adolescent boys)
- Each condition had a different soundtrack
- Heart rate and galvantic skin responses were some physiological measures that were taken from the participants
Results: Trauma condition showed much higher physiological measures of stress than other two conditions (reacted more emotionally)
**WATCH ECOLOGICAL VALIDITY AND ETHICS
Heider (1958)
**USE FOR: situational/dispositional factors in behaviour
aka Attribution theory
Based on assumption that people are naive scientists who try to explain observable behaviour.
- Tend to look for causes and reasons for other people’s behaviour because they feel that there are motives behind behaviour
- “Intuitive psychologists” who construct their own causal theories of human behaviour
- Construct causal behaviours because they want to be able to understand, predict, and control the environment around them
People want to be able to predict the world, so they look for causes, rational or irrational.
Ross (1977)
**USE FOR: errors in attribution
aka Fundamental attribution error (FAE)
When someone places more emphasis on internal factors (personality) rather than the circumstances.
- Ross, Amabile and Steinmetz (1977)
EVALUATION: (*positive; -negative)
+ Promoted common understanding of how people are judged in the world.
+ Many supporting studies
- Culturally biased (focus on individualism)
- Original studies do not look at how long an interaction is made between two people (which can change judgement)
