ABSTRACT
Things change. And yet, the precise point at which they do – that is, the change threshold – is often harder for people to discern, especially in rich everyday domains of self and social judgment (e.g., judging the precise point at which one’s relationship has “officially” eroded or the precise point at which bad actors have “officially” reformed). The traditional approach to understanding people’s crossing of these change thresholds has assumed a more bottom-up process: here the assumption is that things change at some objective, external, and stable point, within the stimulus (versus within the perceiver) – which people can passively detect so long as they have the right tools. In contrast, this chapter approaches this issue through the lens of a more top-down process: here the assumption is that things change at a subjective, internal, and dynamic point, within the perceiver (versus within the stimulus) – which people actively construct on the spot. This chapter reviews diverse and converging evidence in support of this top-down approach. Ultimately, I argue that by understanding people’s crossing of change thresholds as a top-down (versus bottom-up) process, psychological research on change judgment can advance more nuanced insights into when and why people judge change (in)accurately.
