Validating the Creature Believability Scale for Videogames

摘要

We present the validation of a scale to assess creature believability in videogames. We define Creatures as all zoomorphic entities not qualifying as fundamentally human-like, whether possessing or not anthropomorphic features. The scale, derived from a previous research, contains 26 items in 4 dimensions - Biological/Social Plausability, Relationship with the Environment, Adaptation, and Expression. The results of a Confirmatory Factor Analysis, using 19 subjects, originated a model with 4 factors, a CFI of 0.795, and RMSEA of 0.111. While not a good fit, it is very close to a mediocre fit, which is a potentially promising result. Further validation is needed with more subjects in the future.
