Introduction To Psychological Testing Paper

adit To Psychological Testing PaperThe study ofperson and his characteristics is themost weightytasksof mental science.Development of psychological science is characterized with significant increase in interest to problems of psycho symptomatic.The aim of modern psycho diagnostic is question of characteristics and differences between individuals and groups in a systematic manner.The task of such question in the most common form is definition of mental and psychological characteristics of individuals and their intra-individual relationships.Psychological see is thebasis forpsycho diagnosticsofpeopleandthe posteriorof practicalpsychology. The aim of this paper is to define the concept of psychological hear, chance on its major categories, the concepts of dependableness and validity, and other fundamental questions associated with psychological assaying.The conceptof a psychological dischargeand its maincharacteristicsThe scope of psycho diagnostic includes a set of various diagnostic modes to identify psychological characteristics of man.It represents a bridge deck between general and applied psychology, and in relation to the methods intentiond, it acts as a common ground that unites all aras of their practical application. Practical psycho diagnostics solves some typical problems, which include the following1.To record certain psychological properties or behavior in a person.2.Determine the degree of increase of these properties and their expression in limited quantitative and qualitative terms.3.Description of diagnostic psychological behavior of a person4.Comparison of the degree of growth of psychological characteristics in different people.The standardized psycho diagnostic methods, allowing obtaining alike(p) quantitative and qualitative indicators of the degree of development of the properties in people, are called psychological tests.Under standardized techniques is meant that they havestrictlydefinedrulesof application,rangingfrom studying the mail serviceand ending withthe methods of calculationandinterpretationof results.The literature presents a great variation of definitions of psychological testsPsychological test is essentially an objective and standardized cadence of a sample of behavior (The American Psychological Association).Test is a standardized, often time-limited study designed to establish the quantitative (and qualitative) individual psychological differences (The American Psychological Association).Under test is understood a specific tool for evaluating the psychological qualities of the individual, which consists of set of tasks or questions, offered under standard conditions and is intend to identify particle types of behavior (The American Psychological Association)Objectivity,validityandreliablenessare the main requirementsto the test.It is necessary to consider these concepts and to discuss how they impact the knit stitch of psychological testing.Objectivityof a psychological testmea nsthat pristineindicators, evaluationand interpretationof data do notdepend onthe behaviorandsubjectivejudgmentsof the experimenter.Developmentof testing tasks, its procedure, processingof test resultsis carried step to the foreaccording to certainstandardrules.To achieveobjectivity,a psychological testmust follow the nextconditions calibration ofprocedures of conductingthe testto allow equivalenceof its results standardisation of testperformance evaluation Definition of result normsof the testforcomparisonthem withresultsgot from theprocessing of test data.These three conditions are referred to as the stages of standardization of psychological tests. During the development of a test certain standardization procedures are carried out, which include three stages1.The first stage of standardization of psychological tests is to establish analogous testing procedures.2.The second phase is to establish a uniform evaluation of the test the standard interpretation of the results and pr e-standard evaluation.3.The third stage of standardization of psychological tests is to determine the norms of the test.Norms are necessary in the interpretation of test results (primary parameters), as a benchmark with which to compare testing data.For example, in tests of intelligence the primary received IQ is correlated with standard IQ (43, 44, 45 points in the test of Raven).If the IQ received by respondent is preceding(prenominal) normative, as 60 points, we can talk almost of the respondent as high.If the resulting IQ is demean than the norm, then the level of intelligence is low, if the received IQ is 43, 44 or 45 points, then it is average. (Ford-Martin, 2004)All methods of psychological diagnosis, both(prenominal) standardized and non-standardized, are aimed at measuring personality traits and characteristics of intelligence.Each method is designed to measure a certain personal characteristic, and information about the extent to which the test actually measures it is known as the concept of validity. impellingmethod oftestingcan becreated, ifit passedallthe stages ofvalidation,when it meets requirements of both generalandpractical validity.Practicalvalidity describesthe testnot byitspsychologicalcontent,but in termsofitsvalue for achievingcertainpracticalgoals(prediction,diagnosis). (Messic, 1980)The digest importantcharacteristic oftestsare their reliability. Reliabilitymeansconsistency oftestresultsof eachtesting attempt with the same subject,with theresultsof his firsttest.Absolutereliability ofthe testdoes notexist, and errorsare allowed,butthe higher arethey,the lower is thetestreliability. The highreliability ofthe testing methodmeansthatitaccuratelymeasuresthe characteristic.Thesethree basic characteristics ofpsychological testdetermineitsuse in practicalpsychology.ConclusionPsycho diagnosticsisan areaof psychological science, andat the same timethe most importantformof psychological practice,that is associatedwith the development and u seof variousmethodsof recognitionof individualpsychological characteristics of people.Psycho diagnosticsis aset ofmethods and tools fordiagnosisof mentalcharacteristics of man.One of suchmethodsistesting.The use ofpsychologicaltestsis aimedto investigate the characteristicsof person, and provideinformationabout mentalproperties ofa particularperson(the subject).An effective psychologicaltestshouldmeet requirements suchas objectivity,validityandreliability,in this caseitgivesthe correct results,which canbeinterpretedand appliedin practicalpsychology.
