People all around the world live with cats and cats engage in many social behaviors toward their owners. Olfaction is one of the most important sensory abilities in cats, yet its role in recognizing humans remains unclear. In this study, we assessed the role and characteristics of olfaction in the discrimination of known or unknown humans by cats using ethological methods. Whether cats exhibit a lateralization of nostril use in response to a variety of olfactory stimuli, exposure experience, inter alia, was investigated. Cats were simultaneously presented with three odor stimuli: that of a known person (owner), an unknown person, and a blank control. Responses to the cat 2 scale (Feline Five) and the cat–owner relationship scale (CORS) were collected from cat owners through questionnaires. It was observed that cats spent a substantially longer time sniffing the odor of an unknown person than that of a known person, indicating the use of their sense of smell to distinguish between heterospecific (human) individuals. While responding to odor stimuli from unknown humans, the cats displayed marked lateralization in the use of one nostril or another. An association was observed between the first odor the cat sniffed among known, unknown, and blanks and the personality score. A strong correlation was found between the number of repetitive sniffing odors and personality scores in male cats. No association was evident between the cat’s behavior and the cat–owner relationship score. Rubbing of their faces against an object immediately after sniffing it was observed and thus a possible relationship between the olfactory exploration and subsequent rubbing (odor-marking) behavior in cats is postulated. However, this relationship warrants further investigation along with the theory of whether cats are able to recognize a specific person from olfactory cues.

challenging paper for computational psychiatry, but it's luckily not just a black/white picture with possibly state being better captured by behavioral tasks
"Questionnaire-based measures can provide little insights on cognitive mechanisms as they rely only on verbal and mnesic processes. By contrast, behavioral measures and computationally derived parameters
may go beyond explicit processes and capture more accurately states than traits, which may be useful in informing therapeutic strategies in the short run (for example, capturing state impulsivity that may help to adapt a psychotropic treatment when facing a patient with suicidal ideation). Altogether, our results represent a cautionary tale about the utilization of behavioral tasks and model parameters as tools for investigating inter-individual differences along therapeutically or diagnostically relevant time windows, and about the challenges facing computational phenotyping for diagnosis and prognosis."

Reinforcement learning task-based behavioral and computational measures displayed low test–retest reliability at the individual level. Also in contrast to self-assessed personality measures, behavioral and computational measures were poor predictors of mental health measures, representing a challenge for computational psychiatry.
