Timing in Color Learning
One of von Frisch’s students, Elizabeth Opfinger, observed that bees would learn color when approaching a feeder. Menzel took this question further: when do bees register and learn color? He wanted to know if bees registered color before, during, or after receiving their sugar-water reward. In order to explore this intriguing question, Menzel displayed the color beneath a rewarded dish at different stages of the honey bee feeding process: during approach, feeding and departure.
The outcome of this experiment revealed that bees register color during both the approach and feeding stages of the exposure process. In order for a bee to accurately remember a given color, it must be present for approximately five seconds in total. Although it varies slightly, Menzel and his colleagues found that bees usually remember best when the stimulus is present for about three seconds during the approach and two seconds after landing and beginning to feed.

Famous quotes containing the words timing, color and/or learning:
“Is it a new spring star
Within the timing chill,
Talking, or just a mime,
That rises in the blood
Thin Jack-and-Jilling seas
Without the human will?”
—Allen Tate (1899–1979)
“‘Twas mercy brought me from my Pagan land,
Taught my benighted soul to understand
That there’s a God, that there’s a Saviour too:
Once I redemption neither sought nor knew.
Some view our sable race with scornful eye,
“Their color is a diabolic die.”
Remember, Christians, Negroes, black as Cain,
May be refin’d, and join th’ angelic train.”
—Phillis Wheatley (c. 1753–1784)
“I can’t make head or tail of Life. Love is a fine thing, Art is a fine thing, Nature is a fine thing; but the average human mind and spirit are confusing beyond measure. Sometimes I think that all our learning is the little learning of the maxim. To laugh at a Roman awe-stricken in a sacred grove is to laugh at something today.”
—Wallace Stevens (1879–1955)
