Target Effects

We present the first part of a fully parametrized mathematical model of person judgment, in an attempt to streamline and better organize theory in this research area. The model integrates several key concepts from Kenny’s (1994) Weighted Average Model and Brunswik’s (1956) lens model with one another. It incorporates time as a continuous variable and also accounts for target-effects, situation-effects, target by situation interaction-effects, randomness overall and between-target differences in randomness. All of these can influence the average level of a substance variable that may be observed by perceivers („cues“) and thus inform their judgments of targets. We discuss the model’s implications with regard to reliability, inter-rater agreement, and predictive validity. We also explain how the model connects to – and sometimes helps specify – several important concepts from the person judgment literature.
