Description
A peer-reviewed research article from Europe PMC (2025). SummaryIn humans, trace conditioning—where a temporal gap separates conditioned (CS) and unconditioned (US) stimuli—requires awareness and is sensitive to distraction, unlike delay conditioning. Here, we show that honeybees exhibit comparable features, suggesting cognitively demanding processes akin to awareness. Using the olfactory conditioning of the proboscis extension response, we found that bees learned in both paradigms, but trace conditioning resulted in weaker acquisition and memory. High-resolution video analysis revealed delayed response latencies and altered licking dynamics during trace learning.
