Yes definitely.

Faulkner started noticing when our hockey team's announcers would get excited about a potentially impending goal. That soon became his cue to watch US... so we reinforced the goal-scored happy dance with a treat. Over the years he's added awareness of specific players' names approaching the net, being likely to score and set off the sequence of celebratory dance moves. He can tell network from hometown announcers and home games from away games-- when the buzzer sounds for us or for the enemy. He can tell a replay from a fresh goal... all by learning what our behavior means and by watching us. He's geriatric now; may be his last hockey season.
