Manipulating anthropomorphic inferences about NAO: The role of situational and dispositional aspects of effectance motivation

Abstract

In an experiment we empirically tested one key determinant of Epley's Three-Factor Theory of Anthropomorphism: Specifically, we investigated the interplay of both dispositional and situational facets of effectance motivation in predicting anthropomorphic inferences about the robot NAO. That is, we manipulated the predictability of the robot's behavior and whether participants anticipated an interaction with NAO. Innovatively, we also examined interindividual differences in participants' desire for control, a dispositional aspect of effectance motivation. Taken together, we go beyond previous work by (1) increasing ecological validity of the experimental setting; by (2) extending the range of measures to assess anthropomorphism, and by (3) examining the role of contextual and dispositional components of effectance motivation for anthropomorphism. Because this is the first work to study the interplay between these factors, our work contributes to a better theoretical and empirical understanding of psychological anthropomorphism.

Cognitive Impact of Social Robots: How Anthropomorphism Boosts Performances

“…Third, the SFI effect in the social condition should be mediated by the inferences made about the robot. Indeed, according to previous research showing that social interaction promotes the attribution of human traits [6], [60], we hypothesized that the more highly the participants perceived the robot on the universal dimensions of warmth and competence used in social categorization, the more sensitive they should be to its passive presence, thus resulting in a higher SFI. The same phenomenon should occur as a function of the level of perceived shared human traits.…”

Human-Robot Similarity and Willingness to Work with a Robotic Co-worker

“…Similarity has also shown to be central to understanding interaction with robots [13,14]. This research can also be categorized into surface-level and deep-level similarity.…”

Loneliness makes the heart grow fonder (of robots) — On the effects of loneliness on psychological anthropomorphism

“…However, little experimental research has investigated the effects of loneliness on wide range of measures of psychological anthropomorphism. [e.g., [6][7][8].…”

“…Human essence attribution to the robot was measured using 20 personality traits that have been shown to be valid measures of psychological anthropomorphism [7,8]. These human nature and human uniqueness traits [6][7][8].…”

“…These human nature and human uniqueness traits [6][7][8]. were combined to form a reliable index of human essence (human nature: curious, friendly, fun-loving, sociable, trusting, aggressive, distractible, impatient, jealous; human uniqueness: polite, broadminded, humble, organized, thorough, cold, conservative, hard-hearted, rude, and shallow; α = .86).…”
