1. Theory/ies on which the study is based
• Helpingbehaviourreferstovoluntaryactionsintendedtohelpothersandisaformofprosocialbehaviour.
• Theoriesabouthelpingbehaviourinclude:
- Kinselectiontheory:thisreferstothetendencytoperformbehavioursthatmayfavourthechanceofsurvivalofpeoplewithasimilargeneticbase(e.g.Hoffman,1981).
- Reciprocalaltruism:thisholdsthattheincentiveforanindividualtohelpinthepresentisbasedontheexpectationofthepotentialreceiptinthefuture(Trivers,1971).
- Responsibility-prosocialvalueorientation:holdsthatastronginfluenceonhelpingbehaviourisafeelingofandbeliefinone’sresponsibilitytohelp,especiallywhencombinedwiththebeliefthatoneisabletohelptheotherperson(Staub,2003).
- Socialexchangetheory:peoplehelpbecausetheywanttogaingoodsfromtheonebeinghelped.Theycalculaterewardsandcostsofhelpingothers,aimingtomaximisetherewardsandminimisethecosts(Foa&Foa,1975).
• Milgram(1970)proposedthatpeopleinurbanareasarelesshelpfulthanthoseinruralareasbecausetheycopewithstimulusoverloaddifferently:urbandwellersrestricttheirattentionmainlytopersonallyrelevantevents.Strangers,andtheirsituationsofneedmay,therefore,gounnoticed.

2. Background to the study
• Studiesconductedinseveraldifferentcountries(includingtheUSA,SaudiArabiaandSudan)havefoundthatpeoplelivinginurbanareastendtobelesshelpfulthanthoseinruralsettings(Hedge&Yousif,1992;Yousif&Korte,1995).
• Virtuallyallofthestudiesofcommunitydifferencesinhelpinghavefocusedonthesinglevariableofpopulationsize,mostoftentestingthehypothesisthatthetendencytohelpstrangersdeclinesasthesizeofthecityincreases.Steblay(1987)foundgeneralsupportforthishypothesiswiththedeclineinhelpingratebeginningatpopulationsof300,000.Shealsofoundthaturbanenvironmentsof300,000peopleormoreandruralenvironmentsof5,000peopleorlessweretheworstplacesifonewaslookingforhelp.
• Amajorculturaldifferenceinhelpingbehaviouristhedifferencebetweencollectivismandindividualism.Collectivistsattendmoretotheneedsandgoalsofthegrouptheybelongto,andindividualistsfocusontheirownselves.Therefore,collectivistswouldbemorelikelytohelpingroupmembers,butlessfrequentthanindividualstohelpstrangers(Triandis,1991).
• Althoughmanystudieshavedemonstratedthathelpingratesdifferbetweencommunitiesinasinglecountry,almostnosystematiccross-culturalresearchofhelpingbehaviourhadbeenconductedpriortothisstudy.
• Theaimofthisstudywasthereforetolookathelpingbehaviour,inawiderangeofcultures,inlargecitiesaroundtheworldinrelationtofourspecificcommunityvariables:(i)populationsize(ii)economicwell-being(iii)culturalvalues(individualism-collectivism,simpatia)(iv)walkingspeed(paceoflife).

1. Theory/ies on which the study is based
• Attentionhasaselectivenature.
• Broadbent(1958)arguedthattheworldiscomposedofmanymoresensationsthancanbehandledbytheperceptualandcognitivecapabilitiesofthehumanobserver.Tocopewiththefloodofavailableinformation,humansmustselectivelyattendtoonlysomeinformationandsomehow‘tuneout’therest.Attention,therefore,istheresultofalimited-capacityinformation-processingsystem.
• Almostallearlymodelsofattentionassumedserialprocessing,astep-by-stepprocessinwhicheachoperationiscarriedoutinturn.ThefirstofthesewasBroadbent’s(1958)filtermodel,followedbyTreisman’s(1964)attentionmodelandthepertinencemodel(Deutsch&Deutsch,1963;Norman,1969).
• Earlyattemptstoexplaindividedattention,suchasKahneman’s(1973)centralcapacitytheory,alsoassumedserialprocessing.
• However,Allport’s(1980b)multi-channeltheoryofdividedattentionholdsthattwoormoreoperationscanbecarriedoutatthesametime.
• Therearetwomainmethodsofstudyingattention:
(i)Selectiveattention–herepeoplearepresentedwithtwoormoresimultaneous‘messages’,andareinstructedtoprocessandrespondtoonlyoneofthem.Themostpopularwayofdoingthisistouseshadowinginwhichonemessageisfedintotheleftearandadifferentmessageintotherightear(throughheadphones).Participantshavetorepeatoneofthesemessagesaloudastheyhearit.TheshadowingtechniqueisaformofdichoticlisteningwhichwasfirstusedbyCherry(1953)whenhestudiedthecocktailpartyphenomenon.
(ii)Dividedattention–thisisadual-tasktechniqueinwhichpeopleareaskedtoattendandrespondtoboth(orall)themessages.Whereasshadowingfocusesattentiononaparticularmessage,thedual-taskmethoddeliberatelydividespeople’sattention.

• Inthefieldofmoraldevelopment,moralityisusuallydefinedasprinciplesforhowindividualsoughttotreatoneanother,withrespecttojustice,others’welfare,andrights.
• Themaintheoriesofmoraldevelopmentinclude:
• (a)Freud’spsychoanalytictheory(circa1930).Freudbelievedthatthepersonality(psychicapparatus)comprisesofthreeparts:theid,egoandsuperego.Theidcontainseverythingthatisinherited,thatispresentatbirth,theinstincts.Theegoisapartoftheidwhichbecomesmodifiedbythedirectinfluenceoftheexternalworldandrepresentsreasonandcommonsense,incontrasttothepsychewhichcontainsthepassions.Notuntilthesuperegohasdevelopedcanindividualsbedescribedasmoralbeings.Thesuperegorepresentstheinternalisationofparentalandsocialmoralvalues.Therearetwomainaspectsofthesuperego,theconscienceandtheego-ideal.Theconsciencerepresentsthepunishingparentandimposesfeelingsofguiltforimmoralthoughtsordeeds;whereastheego-idealrepresentstherewardingparentandisresponsibleforfeelingsofprideandsatisfaction,for‘good’thoughtsordeeds.
• Freudproposedtheexistenceofatensionbetweentheneedsofsocietyandtheindividual.AccordingtoFreud,themoraldevelopmentproceedswhentheindividual’sselfishdesiresarerepressedandreplacedbythevaluesofimportantsocialisingagentsinone’slifesuchasparents.

• (c)Piaget’scognitivetheory(1965).Piagetfocusedontheindividual’sconstruction,construalandinterpretationofmoralityfromasocial-cognitiveandsocial-emotionalperspective.Tounderstandadultmorality,Piagetbelievedthatitwasnecessarytostudybothhowmoralitymanifestsinthechild’sworldandthefactorsthatcontributetotheemergenceofcentralmoralconceptssuchaswelfare,justiceandrights.Interviewingchildrenusingtheclinicalinterviewmethod,Piagetarguedthatyoungchildren(tenyearsofageandyounger)werefocusedonauthoritymandates,andthatwithagechildrenbecomeautonomous,evaluatingactionsfromasetofindependentprinciplesofmorality.

• ThefollowingtheoriesofmoraldevelopmentarereferredtointheoverviewofKohlberg’sstudy,‘Thechildasamoralphilosopher’:
(a)Freud’spsychoanalytictheory
(b)Skinner’sbehaviouristtheory
(c)Piaget’scognitivetheory
(d)Kohlberg’scognitivetheory.
• Sweetser(1987)proposedafolkloristicmodeloflying.Shesuggestedthattheconceptoflyingisnotsimplyacognitiveconstructdefinedbysuchkeysemanticfeaturesasfactuality(whetherastatementreflectsthetruth),intention(whetherthespeakerintendstodeceive),andbelief(whetherthespeakerbelievesthestatement)alone,butitisalsoasocio-culturalconstruct.Shearguedthattheunderstandingoflyingisgreatlyinfluencedbytheculturalnormsandmoralvaluesinwhichindividualsaresocialised.However,untilthisstudy,littlesystematicdevelopmentalevidencehadbeenfoundtosupportthisproposal.

thetestsandachievedgoodtestresults.AccordingtoYerkestherewasalsoa‘steadystreamofrequestsfromcommercialconcerns,educationalestablishmentsandindividualsfortheuseofarmymethodsofpsychologicalexaminingorfortheadaptationofsuchmethodsforspecialneeds’.
