Using an abstract geometry in virtual reality to explore choice behaviour: visual flicker preferences in honeybees

Area of Science:

• Animal behavior
• Neuroethology
• Sensory ecology

Background:

• Closed-loop paradigms are effective for studying visual choice and attention in small animals.
• Existing paradigms often limit the variety of choices and are constrained by classical conditioning.
• Investigating stimulus preferences requires methods that allow for complex, historical context-dependent choices.

Purpose of the Study:

• To introduce a novel closed-loop behavioral paradigm for studying choice behavior in animals.
• To investigate visual flicker frequency preferences in honeybees (Apis mellifera).
• To explore how novelty and historical context influence stimulus preferences.

Main Methods:

• Development of a novel closed-loop virtual reality paradigm with interconnected binary choices.
• Presentation of competing visual flicker stimuli to honeybees.
• Analysis of stimulus selection to determine preferences and avoidance.

Main Results:

• Honeybees exhibited significant preferences for 20-25 Hz flicker frequencies.
• Higher (50-100 Hz) and lower (2-4 Hz) flicker frequencies were avoided.
• Avoided stimuli became more attractive when novel, indicating novelty salience can override innate preferences.
• Preferences remained consistent across different experimental conditions, including multiple simultaneous choices.

Conclusions:

• Honeybees can discriminate between different visual flicker frequencies.
• The novel paradigm allows for the study of historical context in choice behavior.
• Novelty plays a significant role in overriding established visual preferences in honeybees.
• This recursive virtual reality environment offers a new approach for studying animal visual discrimination and choice behavior.
