Most definitely bass can be conditioned to do tricks in a laboratory. "Learning is acquiring new or modifying existing knowledge, behavior, skills, values, or preferences and may involve synthesizing different types of information." A lake or river environment doesn't allow fish the time or opportunity to be conditioned to one specific lure or lure class. A fish my see the lure once in its lifetime and maybe get hooked, but a year down the road forget it ever saw the lure.
Here's an idea (or two) to think about (opinions welcome). The complexity of a bass's brain as compared to a dolphin's or parrot's brain is ..well.. a no brainer! : But when you think of all the fish you've caught in all their different stages of life, can't you see a few analogies to higher forms of animal life behavior?
For example, juvenile bass are much more aggressive on average than an older bass. Young puppies show the same aggression and hyperactivity. Both have one thing in common - play.
Young fish seem to do the same.
All young push the limits of their limited abilities - bass are no different. They attack something they don't realize they can't consume. Anyone catch a 6" bass on an 8" lure? They may attack to eat, but many attack because the moving object is there and they feel safe to just capture it, maybe testing themselves and the lure they've never experienced. Young bass are apt to chase a lure and attack it several times on one cast, older, lazier bass not so, especially those with large pot bellies!
Older bass may also testobjects they've never seen if the object (lure) gets their attention, holds it and become irresistible at least for the moment. Maybe an hour later nothing you do with the lure will get even a whiff.
I compare a bass's intelligence (stored knowledge) and learning ability (based on its limited capacity to store data and to reason) to that of an eight month old infant. I believe a bass's mentality in the wild can't evolve much further. In this light, a two year old bass is similar to an infant when it comes to moving objects. For instance, a baby's mobile gets different infant reactions in a day's time - joy, excitement, irritation, the urge to touch it, yank it, mouth it. The toy may also be completely ignored (depending how wet his/her diaper, hunger pains and crankiness). But if the mobile falls down and even bruises an infant's head, he most likely will not be afraid of it the next day and back to observing and being fascinated.
Bass go through different stages in their lives and in one day's time. Youthful exuberance has been touched on. An older bass's vulnerability to strike a lure depends on the stage it's in; the length of those stages vary daily. In any order, the stages are: sedate and lazy; mildly interested in new objects that come within its space; more irritable and maybe more apt to test/ mouth the object) after giving it its undivided attention; very irritable and hyperactive - it will eat your sneaker!
Fish and animals in general, first need to feel safe and in charge of their immediate space. If a lure's presentation and action doesn't turn an active stage into a sedate stage, you have a window to catch it.
Sometimes that window is nailed shut, just like it's mouth!
