A truly integrated cognitive assessment
Step 1
A selection of natural images are shown to the participants
In the ICA test, several natural images are briefly shown to participants and they are asked to respond as quickly and accurately as possible to indicate whether they’ve seen a pre-specified image category.
Step 2
The task is a visual challenge
Images are first represented on the retina, then transferred to the early visual cortex
Step 3
The hierarchy of the visual cortex is engaged in quick succession
From the early visual cortex, image representations ascend the hierarchy of the visual cortex to intermediate and then higher visual areas where a percept of the presented image is formed.
Step 4
Images are translated to movement in the motor cortex
The motor cortex is engaged to prepare for an appropriate motor response such as press a yes/no button.
Step 5
Evaluations are based on comparison with an accurate dataset
Artificial intelligence algorithms are used to cluster test performance in terms of accuracy, speed and image properties.
