Some captive apes have more experience participating in research than others. Could this prior experience affect how they think and behave, biasing results from cognitive studies?

Numerous companies sell neurofeedback devices directly to consumers. The idea is that by measuring a person’s brain activity and showing it to them in real time, the individual can learn to self-regulate their brainwaves and, in turn, change their behavior. Proponents of neurofeedback say it can improve attention, mood, sleeping habits, meditation, and even athletic performance.
