NROC34H3 Lecture : Article 14 - Pattern Recognition in Honeybees.doc
Document Summary
This may be in addition to the first process: do bees use, only memorized intensity distributions, only orientational cues, combo of the 2, horizontal (+) vs. vertical (-, results: Learning phase: bees showed choice frequency of 0. 93 for. Testing phase: tested on 2 horizontal gratings: one was identical to + while the other was shifted by period. If bees were using only memorized intensity distribution to distinguish btn the patterns, you would expect them to discriminate btn these 2 horizontal gratings; they should actually prefer the + training pattern even more strongly b/c the negative. Testing pattern produces less overlap with the memorized intensity distribution than does the vertically oriented pattern (from learning phase: but, the bee"s preference for the + training pattern was lower than in the learning test clearly, the. Between the 2 patterns when both had the. Now the bees were able to distinguish between the 2 patterns in significant way.
