The Solomon four-group design is a research method developed by Richard Solomon in 1949. [1] It is sometimes used in social science , psychology and medicine. It can be used if there are concerns that the treatment might be sensitized by the pre-test . [ 2 ]
In psychology, compensation is a strategy whereby one covers up, consciously or unconsciously, weaknesses, frustrations, desires, or feelings of inadequacy or incompetence in one life area through the gratification or (drive towards) excellence in another area. Compensation can cover up either real or imagined deficiencies and personal or ...
The social compensation hypothesis has been applied to research in online dating. [4] In a study by Poley and Luo, the social compensation hypothesis, stating that people high in dating or social anxiety and low in social competence , tend to use online dating to compensate for social deficits, was not supported.
The results of their experiments did not support these claims. Newell & Fernandez and Richter & Späth tested the non-compensatory prediction of the recognition heuristic and stated that "recognition information is not used in an all-or-none fashion but is integrated with other types of knowledge in judgment and decision making." [23]
[5] [6] Compensatory methods such as TOPSIS allow trade-offs between criteria, where a poor result in one criterion can be negated by a good result in another criterion. This provides a more realistic form of modelling than non-compensatory methods, which include or exclude alternative solutions based on hard cut-offs. [ 7 ]
In statistics, econometrics, political science, epidemiology, and related disciplines, a regression discontinuity design (RDD) is a quasi-experimental pretest–posttest design that aims to determine the causal effects of interventions by assigning a cutoff or threshold above or below which an intervention is assigned.
Internal validity, therefore, is more a matter of degree than of either-or, and that is exactly why research designs other than true experiments may also yield results with a high degree of internal validity. In order to allow for inferences with a high degree of internal validity, precautions may be taken during the design of the study.
Freud defined cathexis as an allocation of libido, pointing out for example how dream thoughts were charged with different amounts of affect. [5] A cathexis or allocation of emotional charge might be positive or negative, leading some of his followers to speak of a cathexis of mortido as well. [6]
