Sociality Motivation and Anthropomorphic Thinking about Pets

Sociality motivation, the need to feel socially connected with others, has been proposed as an important determinant of individual variation in anthropomorphic thinking. Specifically, it has been suggested that people who are socially isolated or disconnected will tend to infer more human-like mental states in animals and other nonhuman agents (computers, robots, metaphysical beings, etc.), than those who have higher levels of contact with other people. We investigated this hypothesis in a community-based sample of cat and dog owners, measuring degree of anthropomorphism by asking them which emotions they believed their pet was capable of experiencing, how likely they were to rely on it for social support, and how attached they were to it. Structural measures of social disconnection, including the number of other adults living in the household and the number of social contacts outside the home, were not generally associated with the tendency to think anthropomorphically about pets. However, owners living in households with no children (under the age of 16 years) reported higher levels of attachment to their pet than did those with children (B = 1.678, p < 0.001), and felt that they derived relatively more social support from it than they did from humans (F_(1,244) = 4.997, p < 0.05, partial η² = 0.020). In addition, a trait-based indicator of social disconnection (self-reported anxiety about human social relationships) was associated with a heightened tendency for owners to report turning to their pet for support (F_(1,244) = 19.617, p < 0.001, partial η² = 0.074), and attributing more human-like emotions to it (F_(1,244) = 8.354, p < 0.005, partial η² = 0.033). These findings support a link between social disconnection and anthropomorphic thinking in a community setting; they also suggest that different forms of social disconnection (structural and trait-based) may generate different types of sociality motivation, and thereby influence different facets of anthropomorphic thinking.
