Albert Mehrabian and James Russel proposed the pad emotional state model that is basically a psychological model where 3 numerical dimensions are employed to categorize different emotions. Here three numerical dimensions are employed to categorize different. The pad model puts forward the following dimensions—pleasure, arousal, and dominance.
Using emotion to evaluate our community: exploring the relationship between the affective appraisal of community residents and the community environment

The Pleasure-Arousal-Dominance (PAD) emotional state model proposed by Mehrabian and Russell in 1974 is the earliest theory of affective appraisal. The core concept of the PAD paradigm, applied initially to theories of environmental psychology, is that the physical environment influences people at the emotional level. This paradigm emphasizes that emotions play an important mediating role between individuals and the environment. People’s emotional state within a specific environmental setting may be described and measured using three, mutually independent polarities: ‘arousal-nonarousal’, ‘pleasure-displeasure’, and ‘dominance-submissiveness’. Meanwhile, the semantic-differences method may be used to develop a set of 18 emotional indicators of bipolar, opposite adjectives, which may be used as an effective indicator to measure the emotional state of respondents under various environmental stimuli (Mehrabian & Russell, 1974). In 1980, Russell et al. reintroduced the ‘circumplex model of affect’ by amending the aforementioned theory (Russel & Pratt, 1980). Many scholars posit that this is the first theory to describe the emotional evaluation of place. This fundamental theory of human emotion shows that human affection is derived from two dimensions: pleasure-unhappiness (value of emotion) and excitement (intensity of emotion; Zhang & Lin, 2011).
