Peter Rossi and colleagues developed a framework for creating vignettes by
systematically combining predictor variables in order to dissect the effects of the variables on
dependent variables
Dependent and independent variables are variables in mathematical modeling, statistical modeling and experimental sciences. Dependent variables receive this name because, in an experiment, their values are studied under the supposition or demand ...
. For example, to study normative judgments of family status, "there might be 10 levels of income; 50 head-of-household occupations, and 50 occupations for spouses; two races, white and black; and ten levels of family size". Since this approach can lead to huge universes of stimuli – half a million in the example – Rossi proposed drawing small

from the universe of stimuli for presentation to individual respondents, and pooling judgments by multiple respondents in order to sample the universe adequately.
Main effect In the design of experiments and analysis of variance, a main effect is the effect of an independent variable on a dependent variable averaged across the levels of any other independent variables. The term is frequently used in the context of facto ...
s of predictor variables then can be assessed, though not all interactive effects.
Vignettes in the form of sentences describing actions have been used extensively to estimate
impression formation
Impression formation in social psychology refers to the processes by which different pieces of knowledge about another are combined into a global or summary impression. Social psychologist Solomon Asch is credited with the seminal research on impr ...

[Heise, D. R., ''Surveying Cultures'', pp. 86-120] In this case, different respondents are presented with each sentence, and some are asked to rate how the actor seems during the event, others rate the object of action, and other respondents rate how the overall action makes the behavior seem. Subgroups of respondents receive different sets of event sentences, and the subgroup data are pooled for final analyses.
Vignettes enable controlled studies of mental processes that would be difficult or impossible to study through observation or classical experiments. However, an obvious disadvantage of this method is that reading a vignette is different from experiencing a stimulus or action in
everyday life.
