Concept

Thebasicprocessofmemoryiscomposedofthreesteps:remembering,keeping,recallingandrecognizing.Recognitionisthebeginningofthememoryprocess.Itistheprocessofrecognizingandrememberingthingsandformingacertainimpression.Preservationisanintensifyingprocessofmemorizingcontentsothatitcanbecomeabetterhumanexperience.Recollectionandrecognitionaretwodifferentformsofrepresentationofpastexperience.Thesethreelinksinthememoryprocessareinterrelatedandrestricteachother.Memorizationistheprerequisiteforretention.Withoutretention,therewillbenorecallandrecognition.Recallandrecognitionareindicatorstotesttheeffectivenessofmemorizationandretention.Fromthispointofview,thesethreelinksofmemoryareindispensable.Thebasicprocessofmemorycanalsobesimplydividedintotheprocessesof"remembering"and"remembering"."Remembering"includesrecognizingandmaintaining,and"remembering"includesrecallingandrecognizing.

Informationprocessingtheorybelievesthattheprocessofmemoryistheprocessofencoding,storingandextractinginputinformation.Onlyencodedinformationcanberemembered.Encodingistheprocessofprocessingandtransformingtheinputinformation.Encodingisthekeystageoftheentirememoryprocess.

Recognition

Classificationofmemorization

1.Accordingtowhetherthememorizationhasapurpose,thememorizationcanbedividedintotwotypes:

Unconsciousmemorization

  • UnconsciousmemorizationmeansnoreservationPurpose,intheprocessofmemorization,thereisnoneedtomakeacertainamountofwillandeffort,andmemorizationoccursnaturally.Forexample,moviesanddramaswehaveseen,storiestoldbyothers,andcertainthingswehaveexperienced.Whenweperceivethem,wehavenointentionofrememberingthem,butthesecontentscanreappearinthemindinthefuture.Itistheunconsciousmind.memory

  • Thecontentoftheunconsciousmindisanimportantpartoftheexperience,anditalsohasasignificantimpactonmentalactivityandbehavior.Whatweexperienceunintentionally,whenweconsciouslyfacecertainsituationsanddealwithcertainproblems,canbeusedasexistingexperiencetohelp.Indailylife,theenvironmentpeoplearein,thepeopletheycomeintocontactwith,andtheworktheydowillcausepeopletobesubtlyaffectedandchangetheirpsychologyandbehavior.Forexample,theculturaltraditionofanationwillinvisiblyaffectthepsychologyoftheentirenation,givingitthecharacteristicsofitsownculture.

  • Unconsciousmindisveryselective.Generallyspeaking,thecontentoftheunconsciousmindhastwocharacteristics:First,thestimulationactingonpeople'ssensoryorgansisofgreatsignificanceorattractingattention.Forexample,peoplewillneverforgetnewthings;thesecondiscontentthatmeetspeople'sneeds,interests,andcanproduceadeeperemotionalexperience.Suchasthesituationwhentakingthecollegeentranceexamination,thesituationonthefirstdayofregistrationattheuniversity,etc.Unconsciousmemorizationhasapositiveeffectonpeople'sknowledgeandexperience.Asteachers,studentsshouldtrytheirbesttomakestudentslearnhappilyinthisway.However,unconsciousmemorizationcannotguaranteethatstudentsacquiresystematicculturalandscientificknowledge.Therefore,intheteachingprocess,alargeamountofmemorizationcontentshouldbeobtainedthroughconsciousmemorization.

Consciouslyremember

  • Itreferstoapredeterminedpurpose,andmustbedoneintheprocessofrecognitionThewilltoworkhardtoremember.Theprocessofconsciousmemorizationiscarriedoutunderthecontrolofthepurposeofmemorization.Thepurposeofthememorizationdeterminesthatthememorizationprocessisaproactivecodingprocessofthememorizationcontent.Thiscodingincludes"whattoremember"and"howtoremember"."Whattomemorize"determinesthedirectionandcontentofmemorization,and"howtomemorize"iswhatmethodcanbeadoptedtobettermemorizethecontenttobememorized.Thememorizationofstudentsinthecourseoflisteningtotheclassiscomposedofthesetwoparts.Eachlessonhasacertainteachingpurposeandtask.Teachersusuallygiveanexplanationfirst,sothatstudentswillhavetheintentiontoremembernewknowledgewithapositiveattitude.Inordertobetterrememberwhattheteachersaid,somestudentstakethemethodoflisteningattentively,thatis,usingmind-memory,andsomestudentstakethemethodofcombiningmind-memoryandnotes.

  • Allpeople'sknowledgeandexperienceareobtainedthroughconsciousandunconsciousmemory.However,intermsoftheeffectofmemorization,consciousmemorizationisbetterthanunconsciousmemorization.Asateacher,understandingthislawofmemorizationwillhelpstrengthentheeducationofstudents'learninggoalsintheteachingprocess.Studentsshouldbeassignedtasksreasonablytoachievegoodteachingandlearningresults.

2.Accordingtotheunderstandingofthematerialduringthememorization,thememorizationcanbedividedintotwotypes:

Mechanicalmemorization

  • MechanicalmemorizationItreferstotheidentificationbymechanicalrepetitionaccordingtotheorderofthematerialwhenthematerialitselfhasnointernalconnectionordoesnotunderstanditsmeaning.Suchastherecognitionofmeaninglesssyllables,placenames,namesofpeople,historicalyears,etc.Thiskindofmemorizationispassive,butitcanpreventthedistortionofmemorymaterials.Forstudents,thiskindofmemorizationisalsonecessary,becausesomeofthelearningcontentdoesneedtobememorizedaccurately,suchastheheightofthemountainsandthelengthoftheriver.Therearealsosomecontentthatislimitedtotheknowledgeandexperienceofstudents,anditisimpossibletotrulyunderstanditsmeaning,butthisknowledgeisimportantforfuturelearningandshouldalsobememorizedmechanically.Forexample,studentsinthefirstandsecondgradesofelementaryschoolrecitemultiplicationformulas.Infact,purelymechanicalmemorizationisrare,andpeoplealwaystrytomakethematerialasmeaningfulaspossibleinthememorizationprocess.Accordingtothepointofviewofinformationprocessingtheory,anindividualshouldcodeanyinputinformationasbestaspossibleaccordingtohisownexperiencesystemorpsychologicalpattern.Ifyourememberaphonenumber,youarenotsimplyrepeatingthememory,butusinghomophonicorfindingpatternstomakeitmeaningful.

Meaningmemory(understandingmemorizing)

Forgetting

Forgettingreferstothephenomenonthatthematerialthathasbeenmemorizedcannotberecalledandrecognized,orthememoryandrecognitionarewrong.Accordingtothepointofviewofinformationprocessing,theforgettingprocessexistsatdifferentstagesofmemory.Forgettingisbasicallyanormalandreasonablepsychologicalphenomenon.Becausethethingsthathavebeenperceivedarenotnecessaryforallmemory;theimportanceofmemorizingmaterialsistime-effective;itisnecessaryforpeople'smentalhealthandnormallife.

Thereasonsforforgettingarenotonlyphysiological,suchasforgettingduetoillness,fatigue,etc.;butalsopsychological.Therearefourmaintheoriesaboutthereasonsforthis:

Short-termmemoryhasthreecharacteristics:

6thcenturyBC,ancientGreeceHumanParmonidesbelievesthathumanmemoryisamixtureoflightanddark(orhotandcold)substances.Aslongasthemixtureisnotdisturbed,thememoryiscomplete.Oncethemixturechanges,therewillbeforgetting.

ThefirstpersontoputforwardanimportantconceptonmemorywasthethinkerPlatointhe4thcenturyBC.Histheoryiscalledthe"waxboardhypothesis".Hebelievesthatpeoplegetanimpressionofthings,justlikethemarkleftbyahardobjectwithedgesandcornersonawaxplate.Afterpeoplegetanimpressionofthings,theimpressionwillslowlyfadeandevendisappearcompletelyovertime.Itisasifthesurfaceofthewaxplategraduallyreturnstoitssmoothness.Theso-called"smoothwaxplate"isequivalenttototalforgetting.Althoughthistheoryisnotperfectandaccurate,itstillaffectsmanypeople.

Untilthe17thcenturyAD,therewasalmostnomajorprogressinmemoryresearch.Inthemiddleofthe17thcentury,the"associative"psychologyschoolrepresentedbyHobbesandLockeappearedinBritain.Hobbesmadeamaterialisticanalysisofthephenomenonofmemory;Lockeputforwardtheterm"association",animportantmemoryphenomenonforthefirsttimeinthehistoryofEuropeanpsychology.Sincethen,"association"hasbecomeaspecializedterm.
