Psychological experiment

Psychological experiment is a joint activity of the subject and experimenter, which is organized by the experimenter and aimed at studying the characteristics of the psyche of the subjects. The process that organizes and regulates the joint activity is communication.
The subject comes to the experimenter, having his own life plans, motives, goals of participation in the experiment. And naturally, the result of the study is influenced by the peculiarities of his personality, manifested in communication with the experimenter. The social psychology of psychological experimentation deals with these problems.
Psychological experiment is considered as a holistic situation. The impact of testing situations on the manifestation of children's intelligence was discovered as early as 1910-1920s. In particular, it was found that the assessment of the intellectual development of children by the Binet-Simon test depends on the social status of their family. It manifests itself in any study, on any sample, at any time and in any country (with rare exceptions). Psychology initially interpreted this fact as a dependency on the “social order” or believed, using F. Galton’s hypothesis about the inheritance of abilities, that the elite of society should consist of highly gifted people and recruit such people.
However, if in a testing situation, different approaches are used when communicating with children from different social strata, as well as speech patterns that are habitual for the child, then there is no difference in the intelligence of children of different social strata. Moreover, Soviet psychologists found higher IQs among children from working families.
Specialists in testing will not accept these results, because when they were obtained, the main condition of the scientific measurement was violated - standardization and unification of the procedure.
It should be noted that all psychologists recognize the importance of the influence of the experiment situation on its results.
