How to express social presence: a comparison of perceptions of social robots' cognitive abilities.
Article in Frontiers in robotics and AI, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In light of the problems posed by an aging society and the associated challenges-particularly regarding the care and support of older citizens-questions arise concerning technological solutions. Social robots equipped with appropriate cognitive abilities can provide support in this area by reducing loneliness and social isolation through communication and personalized interaction. To this end, the robot's perceived social presence is of crucial importance. Social presence (or co-presence) refers to the sense of being with another person and depends on how easily one feels able to access that person's intelligence, intentions, and sensory impressions. This study examined the potential of robots' cognitive abilities for social dialogic interactions with humans, such as (i) unrestricted conversational abilities, (ii) the incorporation of visual cues into interactions, and (iii) memories of individual encounters, and investigates the perceived social presence in each case. In addition, we evaluated the degree of anthropomorphism using the Human-Robot Interaction Evaluation Scale. Our results show a trend toward a higher degree of social presence in terms of visual perception, but only one statistically significant difference out of a total of seven questions on this topic. Memories, as well, had only one statistically significant influence, namely, on the anthropomorphic dimension of disturbance. Gender-specific differences were observed with regard to social presence and the anthropomorphic dimensions. However, these differences are most likely attributable to professional background or certain predispositions rather than to gender itself.
