Triggered

It wasn't that Anurak's brain didn't understand that it was supposed to be triggered by the word ‘Pleasure.’

But the brain is no miracle worker. It must first learn before it can execute.

If Anurak was directly ordered to behave like a horny person after hearing the word ‘Pleasure,’ maybe the brain would have learned faster by recreating what the boy's understanding of the word 'Pleasure and Horny.’ This would have been a case of ‘practice makes perfect.’ But just like King feared, the response would be deliberate and not spontaneous.

This approach stands a chance of wearing off once they stop the training.
