# Advanced Sessions

## Advanced Sessions

Advanced session modes have an added level of difficulty. 

{% hint style="danger" %}
You experience higher cognitive load in advanced sessions, so they should only be attempted later in your training, once you have built the mental skills necessary.
{% endhint %}

### +Optic Flow

+Optic Flow adds an immersive oscillating tunnel in the background of the exercise as a balance dual-task (optokinetic stimulation). 

Levels of difficulty:

* **Easy**: Standing with feet in a line.
* **Moderate**: Standing on 1 foot.
* **Hard**: Balance on Bosu or exercise ball

### +React

+React is a dual task that involves a reaction time test. When the cube flashes, respond as quick as possible, all while maintaining focus on the NeuroTracker exercise.

### +Impulse

+Impulse adds a go/no-go decision as a dual task. While you are tracking the targets, a visual cue will be shown, which you must respond to (grey circle) or not (blue circle).&#x20;

### +Stroop

This mode adds the Stroop test to the exercise. While tracking the targets, you must override your automatic response (reading the word) in favor of a controlled response (naming the ink color).

### +Math

The +Math mode incorporates a math exercise while you track the targets.&#x20;

### +Memory

+Memory adds an object recogntion task to the exercise. At the start of the session you will see a number of reference shapes, which you must recall. During the trial, if the shape in the background matches the reference group, you need to respond. If not, ignore it.&#x20;

### +Distraction

In the +Distraction mode, random targets will be highlighted during the trial drawing your attention. You must overcome this distraction and maintain focus.&#x20;
