Correlation between dichromatic colour vision and jumping performance in horses.

The research article explores the relationship between horse color vision and their show jumping performance depending on the color of fences (blue or green). It was observed that horses in indoor arenas made more faults with blue fences compared to green ones. However, the same experiment conducted outdoors showed no significant difference.

Colour Perception and Jumping Performance in Horses

• The study is based on the understanding that horses have dichromatic color vision, similar to humans with red-green color deficiencies. The research’s primary concern was whether color perception affects equine jumping performance and to what extent the color stimulus might be for a horse.
• The researchers conducted an experiment involving 20 horses and two riders. They used an indoor and outdoor set of green and blue fences to test the jumping performance of the horses. The purpose of this experiment was to ascertain if the color of the fences would influence the horses’ performance.

Indoor vs. Outdoor Performance

• In the indoor arena setting, it was observed that horses made significantly more faults and touches on blue fences as compared to the green ones. The median difference amounted to 2.5 bars for faults and one bar for touches.
• However, when the same experiment was conducted outdoor in a grass arena, there were no significant differences observed between performances on the two colored fences. This suggested that the indoor and outdoor environments might influence the color perception and jumping performance of horses differently.

Gender Differences in Perception and Performance

• The study also explored the difference in color perception and jumping performance based on the sex of the horses. Among the total participants, 4 mares demonstrated a greater difference in faults and touches between the two colors, as compared to the 16 male horses. This suggests that gender might play a role in color perception and performance among horses.

Implication and Future Research

• The findings of this research represent a significant step in understanding the correlation between color perception and jumping performance in horses. However, the authors suggest that further research is necessary to make definitive conclusions. This might involve exploring the influence of contrast with the arena surface, further assessing gender-based differences, and studying the role of color perception in detail.
