and his team randomly assigned groups of 10 or 18 starlet sea anemones to either paired trials in which light and electric pulses coincided or unpaired trials in which the pulses of light and electricity occurred out of sync.
Then they tested their reactions to the light alone. Animals that received light and electric shock together during training adapted their behavior and reacted to light alone after conditioning. By using software to track the body length of the animals at each point in the test, the team also measured the extent of the retractions. They found that the maximum length of retraction was significantly longer in animals trained with the shock and light together compared to the unpaired group.,"these animals displayed a quantitatively and qualitatively different behavioral response compared to control animals that received unpaired stimuli.
