This photo of Don Campbell and Dave Kenny was taken in 1995 in Storrs, Connecticut.   Don talked about the Multi-Trait, Multi-Method Matrix, his experience with Robert Tryon at UC Berkeley as his teaching assistant and “Tryon’s Paradox,” and the social relations model.   He used the phrase “Roshomon Effect” to describe the perceiver effect of the social relations model.   I discuss all of these topic in more detail in my 2018 book “Social Relations Modeling of Behavior in Dyads and Groups” published by Elsevier Press (Academic Press).
