Research on the Behavioral and ERP Characteristics Induced by the Availability Heuristic in Intuitive Decision-Making.
Article in Sensors (Basel, Switzerland), 2025. 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
Humans tend to rely on heuristic strategies for intuitive judgment during decision-making. Existing research proposes an availability heuristic, suggesting that individuals are inclined to use highly available information as a basis for judgment. To explore the behavioral and electrophysiological characteristics of the availability heuristic in information visualization, 24 right-handed participants were recruited for the experiment. Using behavioral and event-related potentials (ERPs) analysis techniques, within-subject behavioral and electroencephalogram (EEG) experiments were conducted under four conditions: polar coordinate system with higher number, polar coordinate system with lower number, Cartesian coordinate system with higher number, and Cartesian coordinate system with lower number. The behavioral results revealed that in the angle estimation task, the polar coordinate condition induced a more significant availability heuristic effect compared to the Cartesian coordinate condition, exhibiting smaller numerical estimation deviations. This indicates that the degree of semantic relevance between the available information and the target task is a critical factor determining the facilitative effect of such information on judgment. The ERPs results showed that the polar coordinate condition elicited smaller N2 and P2 amplitudes than the Cartesian coordinate condition during angle judgment, suggesting reduced semantic conflict and lower attentional demand in task processing under the polar coordinate condition. By providing behavioral and electrophysiological evidence of intuitive decision-making processes, this study lays a theoretical foundation for the rational application of intuitive effects in information visualization design. Furthermore, the findings imply that using available information semantically aligned with the target task can significantly enhance the effectiveness of the availability heuristic, thereby mitigating availability bias.
