Raw behavioral choice data for honeybee discrimination of aperture height across multiple scales

This dataset contains raw behavioral choice data from psychophysical experiments testing the ability of honeybees to discriminate between side-by-side apertures of varying heights. The experiments investigated visual resolution limits by testing bees' ability to choose a taller aperture over a shorter one across three different size scales (Large: 60 mm; Medium: 30 mm; Small: 15 mm). The data is structured as binomial counts, recording the total number of flights (n) and the number of correct choices (k, defined as choosing the taller aperture) for specific relative height differences. These data were used to fit psychometric functions to determine visual discrimination thresholds.
