One thought on “Do Plants Respond to Reinforcement?

  1. Good Job! very interesting idea, I wonder why the negatively spoked to plants grew higher since usually what’s best for a liing organism is to encourage it and do everything you can to put it in the best enviroment possible for it. Maybe for the next time I would use replicates of each one of your conditions, for example you could plant 3 positive plants, 3 negative plants and 3 control plants, that way you could see if the result you are observing is consistent. Keep going!
