pyschology mock 2 Flashcards
what is a repeated measures design
when the researcher uses the same pp in each conditions- test pp 2 or more times
what are strengths of a repeated measures design
- pp varaibles do not differ between conditions as the pp are the same people
- statistical test can be more reliable-there is limited variation between 2 conditions
- you only need 1 group of pp so it is not time consuming an is economical
what are the weaknesses of repeated measures design
-demand charactersistics-pp can compare the different conditions of the study and are more likely to guess the aim
- ordeer effects like practice,fatique and boredom can occur-pp do 2 or more conitions in the study
what is an independant measures design
if 2 groups in an experiment consist of different indiviuals .
eg. a group of boys and a group of girls
what are the strengths of a independant measures design
- no demand characteristics, so pp cant compare different conditions of study and unlikly to guess aim
- order effects like practice,fatigue and boredom are avoided because pp only do one condition in the study
- same test can be used for both groups with only iv manipulated so can be good way to test differences
what are the weaknesses of an independant measures design
- pp variables differ, which could becomes confounding variables
- statictcal test can be less relaible-there is more variation between 2 conditions
- you have to find twice as many people-could be time consuming and uneconomical
what is a matched pairs deign
match every subject in one group with a very similar person in the other group
what are the strengths of a matched pairs design
- pp variables like 1Q,education and culture are controlled because people are paired on similar traits
- order effects are avoided-pp take part in only one condition
- demand characteristsics are less of a problem as pp only take part in 1 condition and arent gonna gusee the aim
what are the weaknesses of a matched pairs design
- pp variables can never be perfectly matched so cannot copletely control this
- matching pp is time consuming and not always effective-close matches can be hard to find
- if 1 person drops out then their pair has to be dropped from data-can be expensive if have to be repliacted
what are the dispositional factors of collective behaviour
- morality
-personality
how does morality affect collective behaviour
- an individuals morality can influence their behaviour in a grou[
- it involves a person sense of what is right or wrong
- people with high moral strength will be less affected by the social norm created by the group
what is a strength and weakness of morality
+ application from nazi germeny as a woman was exucuted for ciculating anti-nazi literature.standing up to what she believed at a great personal cost.some people are willing to sacrifice their life for the good of others
- must also consider situational factors such as deindiviuation and not to do with a persons strong morality
how does personality affect collective behaviour
- people with stronger internal locus of control take greater responsibilty for their own actions
- they are less likely to take part in group behaviour and are more likley to act as indivuals in collective situations compared to those with an external locus of control
what is a strength and weakness of personality
+ tested pp to see if they would report researchers for conducting an unethical study.those willing to speak out had very similr scores on a personality test
- must also consider situational factors of why crowds act,eg prosocial and anti crowd behaviour may be due to deindividuation and not with an internal locus of control
what are the social factors affecting collective behaviours
- social loafing
- deindividuation
- culture
how does social loafing affect collective behavior
- inviduals put in less effort into completing tasks when they are part of a group compared to when alone
- when working in a group the diffusion of reponsibilty occurs as individuals do not need to work as hard
people are less likely to social loaf when: small group,complating task they think are important, competing with another group - it can be reducedwhen people identify and evaluate each indivuals effort in the group task eg allocate specific roles
what are the strengths and weaknesses of social loafing
+ supporting evidence from research on tug of war teams in which each individuals when they join a group worked less hard.indivuals perfromence decreased as more people joined
+ 84 males undergrads were ked to shout loudly on their own or in a group.when pp were in larger groups,they indiviaully make less noise
- does not apply to all tasks like brain storming so the group output was higher than the individual input
how does deindividuation affect collective behaviour
refers to what happens when we lose our sense of individuality
- pyschologists found people tend to become deindividuated when in a crowd as they feel anonymous
- in a crowd,people lose their sense of reponsibilty for what they do.this results in behaviour that would not normally be typical of the person. less able to monitor their own behaviour and judge their actions as their behaviour is part of the group
what are the strengths of deindividuation
+ supporting evidence-a study on children who were dressed in halloween costumes took money nearby
+ interviews with young people who looted during riots said they felt sewpt along by the crowd.they felt anonymous so joined into. so deindiduation can lead to antisocial behaviour
what are the weaknesses of deindividuation
- does not always result in antisocial behaviour.milgrims study was repeated but the pp were dressed different. nurses gave fewer shocks than the KKK pp.but those in their own clothes gace the fewest shocks. deindivisuation is taking on identity of group which s not always antisocial
- another explanation is overcrowding- freedman said overcrowding situations increases excitement and this leads to prosocial behaviour so it can also be explaines through crwoding
how does culture affect collective behaviour
- in collectivists cultures social loafing is less likley to occur as people are prepared to work just as hard for the good of group
- individualistic cultures people are focused on individual needs
what are the strengths o culture as an factor of collective behaviour
+ in one group, they were indivudally identifiable and in the other they werent. the individuals effort was the same on both tasks for chinese pp but not americans-as soon as they thought they were being indivually assesed they increased effort.
what are the weaknesses o culture as an factor of collective behaviour
- cant generalise accross whole country,people vary considerably.they may belong to different religions or political party whihc may have certain values.so national cultures may not be representative in term of collectivists and individualists ideas.
what are the social factors affecting bystander behaviour
- cost of helping
- presence of others
how does cost of helping affect bystander behaviour
- weighing up the costs and rewards of helping a person
- in some circumstances people may decide its too costly to intervene(could get hurt or lose money)
- cost could be low so we help ,so cost of not helping involves guilt
- if the costs outweigh the rewards, we are less likely to help
what is the weakness of the cost of helping
- is not the only factor. piliavin also included the interpretation of the event. is a person does not judge it s an emergency they will not help.so one factor cannot explain why someone will or wont help
how does the presence of others affect bystander behaviour
- we are more likely to help people when we are alone than when we are with other people
2 reasons:
1. sometimes difficult to determine whether or not a siruation is in fact an emergency.we do not like to react and make ourselves look foolish. if they do nothing, we conform to the group.
2. diffusion of responsibilty- a person less likely to take responsibilty for their actions when other bystandrs are present
what are the strengths of presence of others
+ supporting eveidence from darley who recruited students to have discussions over intercom. during, as student(confederate) had a fit and called for help. 85% reported when alone. 31% when they thought there were other bystanders
what are the weaknesses of the presence of others
- faul found bystanders at an emergency were very helpful in very serious sitautions even when there were lots of others around
what are the dispositional factors affecting bystander behaviour
- similatrity to vcitim
- expertise
