Question1(a)
The Turing testisa testof a machine'sabilitytoexhibitintelligentbehavior equivalentto,or
indistinguishable from,thatof a human.AlanTuringproposedthata humanevaluatorwouldjudge
natural language conversationsbetweenahumananda machine that isdesignedtogenerate human-
like responses.The evaluatorwouldbe aware thatone of the two partnersinconversationisa machine,
and all participantswouldbe separatedfromone another.The conversationwouldbe limitedtoa text-
onlychannel suchas a computerkeyboardandscreensothat the resultwouldnotbe dependent onthe
machine'sabilitytorenderwordsasspeech. If the evaluatorcannotreliablytell the machinefromthe
human(Turingoriginallysuggestedthatthe machine wouldconvinceahuman70% of the time afterfive
minutesof conversation),the machine issaidtohave passedthe test.The testdoesnotcheckthe ability
to give correctanswersto questions,onlyhow closelyanswersresemble thoseahumanwouldgive.
The test wasintroducedbyAlanTuringinhis1950 paper "ComputingMachineryandIntelligence,"while
workingat The Universityof Manchester(Turing,1950; p. 460). It openswiththe words:"Ipropose to
considerthe question,'Canmachinesthink?'"Because "thinking"isdifficulttodefine,Turingchoosesto
"replace the questionbyanother,whichiscloselyrelatedtoitandis expressedinrelatively
unambiguouswords." Turing'snewquestionis:"Are there imaginable digital computerswhichwoulddo
well inthe imitationgame?"Thisquestion,Turingbelieved,isone thatcan actuallybe answered.Inthe
remainderof the paper,he arguedagainstall the majorobjectionstothe propositionthat"machines
can think".
In the yearssince 1950, the testhas proventobe bothhighlyinfluential andwidelycriticised,anditisan
essential conceptinthe philosophyof artificialintelligence.
The "standard interpretation"of the TuringTest,inwhichplayerC,the interrogator,isgiventhe taskof
tryingto determine whichplayer–A or B – isa computerand whichisa human.The interrogatoris
limitedtousingthe responsestowrittenquestionstomake the determination.

The ImitationGame,as describedbyAlanTuringin"ComputingMachineryandIntelligence."PlayerC,
througha seriesof writtenquestions,attemptstodeterminewhichof the othertwoplayersisaman,
and whichof the two isthe woman.PlayerA,the man, triestotrick playerC intomakingthe wrong
decision,while playerBtriestohelpplayerC.
ImitationGame vsStandardTuring Test
Controversyhasarisenoverwhichof the alternative formulationsof the testTuringintended.Sterrett
arguesthat twodistincttestscan be extractedfromhis1950 paperand that,pace Turing'sremark,they
are notequivalent.The testthatemploysthe partygame and comparesfrequenciesof successis
referredtoas the "Original ImitationGame Test,"whereasthe testconsistingof ahumanjudge
conversingwithahumanand a machine isreferredtoas the "StandardTuringTest,"notingthat Sterrett
equatesthiswiththe "standardinterpretation"ratherthanthe secondversionof the imitationgame.
Sterrettagreesthatthe Standard TuringTest(STT) has the problemsthatitscriticscite but feelsthat,in
contrast,the Original ImitationGame Test(OIGTest) sodefinedisimmune tomanyof them, due toa
crucial difference:Unlike the STT,itdoesnotmake similaritytohumanperformance the criterion,even
thoughit employshumanperformance insettingacriterionformachine intelligence.A mancan fail the
OIG Test,but itis arguedthat itis a virtue of a test of intelligence thatfailure indicatesalackof
resourcefulness:The OIGTestrequiresthe resourcefulnessassociatedwithintelligence andnotmerely
"simulationof humanconversational behaviour."The general structure of the OIGTestcould evenbe
usedwithnon-verbal versionsof imitationgames.
Still otherwritershave interpretedTuringasproposingthatthe imitationgame itself isthe test,without
specifyinghowtotake intoaccountTuring'sstatementthatthe test thathe proposedusingthe party
versionof the imitationgame isbaseduponacriterionof comparative frequencyof successinthat
imitationgame,ratherthana capacityto succeedat one roundof the game.
Sayginhas suggestedthatmaybe the original game isawayof proposingalessbiasedexperimental
designasit hidesthe participationof the computer.The imitationgame alsoincludesa"social hack"not
foundinthe standard interpretation,asinthe game bothcomputerand male humanare requiredto
playas pretendingtobe someone theyare not.
