Freeze Frame

A critical aspect of focus and attention is alertness. Success with things like memory, problem solving, learning, and higher-order reasoning is driven by our level of alertness. According to studies, one of the qualities that may separate average and above-average achievers from underachievers is a person’s state of alertness.

We may describe ourselves as feeling “in the zone” when we are at the right level of alertness. Being in the zone allows us to perform optimally, shift focus, be productive and multitask. The reason why training your brain to get alertness “in the zone” is so important is the relationship between these other more complex brain operations and alertness.

Two types of alertness have been identified by scientists: phasic alertness and tonic alertness. Your attentional state is determined by these two alertness measures working in concert with each other.

The degree to which you can quickly formulate your responses in any given moment is considered phasic alertness. This type of alertness, which fluctuates millisecond by millisecond, is incredibly important for “selective attention”. This “selective attention” describes your ability to filter out unimportant things while paying attention to important things.

Your overall level of alertness is called tonic alertness, which is critically involved in maintaining your focus on something. In order for higher-order cognition to occur you need the “tone” provided by tonic alertness.

Both your phasic and tonic alertness are targeted in our Freeze Frame  exercises for your brain. Over increasingly longer delay periods your brain is required to maintain a relaxed and ready state of alertness. Throughout the Freeze Frame exercise your brain is required to differentiate between target images and images that are designed to be distractors. During such exercises for your brain, you’ll press the space bar whenever you see a distractor – an object that is not the target. Whenever you see a target, you need to prevent yourself from hitting the space bar – in other words “freeze”!


Although this exercise may sound easy on the surface, the longer the delay between targets the more likely you’ll be tripped up by internal distractions or a wandering mind.


As you move through the levels of the game you’ll experience the following:

  • Your alertness state will be honed to that relaxed, ready and engaged state known as “in the zone”.
  • The exercise will grow more challenging and will adapt to your performance as your phasic and tonic alertness grow closer to optimal levels.
  • The increasing level of challenge will involve images speeding up while distractors become more similar to the target and appear more frequently.
  • Early on, the targets will be identical images while in more advanced levels your target might be a specific element of an image – like a particular person. As a result the task becomes much more difficult because you need to identify any image that contains that person – even if the entire image is not an exact match.
