The interpersonal Circoplex describes state-like personality characteristics and predicts behavior between two people. The dimensions of the model are intended to possess complementarity, whereby individuals seek personalities that integrate and strengthen their characteristics through reciprocity and correspondence (Woodward & Bauer, 2007). This means that high dominance individuals would gravitate towards someone who is submissive and vice versa. In contrast, those with a high level of hostility would attract hostile counterparts. Therefore, the interaction between the personality characteristics of humans and their pets may serve to strengthen the relational bond (Woodward & Bauer, 2007). A growing number of studies have attempted to support the theory that dogs and cats differ in their personality attributes. From these studies, several common factors emerged, such as differences in social behaviors. Higher levels of dominance and hostility have been reported among domestic cats (as cited in Fonberg, 1985). It is not surprising that domestic dogs have more submissive behaviors (as cited in Marder, 1989). Woodward et al. also reflect on previously held theories of attachment to companion animals that suggest that attachment is mediated by the owner's needs and the characteristics of their pet. The purpose of this study is to investigate how the interpersonal circumplex model of personality can be applied to cross-species assessment and to study how complementarity can predict attachment and satisfaction between humans and their pets (Woodward & Bauer, 2007). The authors offered three hypotheses: 1) dog owners will perceive their pets as less hostile and more submissive than cats and will also report similar traits themselves... halfway through the paper... people revealed that neither groups had greater complementarity with their ideal pet, implying that hypothesis 2 was not accepted. Regarding Hypothesis 3, the results of the regression analysis revealed that, as expected, pet behavior and complementarity were positively correlated with animal attachment (Woodward & Bauer, 2007). The goal of the study was to determine the personality characteristics of pets and use the circumplex model to evaluate human-animal bonds. The findings confirm that people who identify with cats and dogs seek complementarity with their pets. However, the results were insignificant between ideal pet interaction and level of complementarity. It appears that the greatest predictor of human-animal attachment is the match between the owner's needs and the interpersonal characteristics of his pet (Woodward & Bauer, 2007).
