... by facilitating learning, memory and decision making. Here, we evaluated learning and memory in foragers of the bumble bee Bombus impatiens trained to simple (unimodal) versus complex (bimodal) signals under restrained conditions. Use of a proboscis extension response protocol enabled us to control the timing...

...; this is not due to the scaling of acceleration performance, however, and may be driven by the allometry of collision avoidance. Insect flight Collision avoidance Bombus impatiens Clutter Environmental complexity Locomotion Natural environments are highly variable over space and time...

... certainty about the value of another component, color hue. We first trained two groups of bumble bees ( Bombus impatiens Cresson) to discriminate between rewarding and unrewarding artificial flowers of slightly different hues in the presence vs absence of scent. In a test phase, we presented these bees...

...Bradley D. Worden; Ana K. Skemp; Daniel R. Papaj SUMMARY We examined the effect of learning a new task on the performance of a previously learned task with the same set of visual cues in bumblebees, Bombus impatiens . Previous studies have shown that given a binary choice at each task, bumblebees...

...Todd Macuda; Robert J. Gegear; Terence M. Laverty; Brian Timney ABSTRACT The present study used previously developed techniques to measure resolution acuity in bumblebees ( Bombus impatiens ). Bees were required to discriminate between horizontal and vertical gratings in a Y-maze apparatus...

...Lars Chittka ABSTRACT Bumblebees were trained in biologically realistic sensorimotor tasks to test how learnt information from more than a single task is organised in memory. Bees ( Bombus impatiens and Bombus occidentalis ) learned to collect sucrose solution from the arms of small T-mazes...
