1. True or false? Brain functioning related to learning is the same in adults and children.
2. For each statement, find the duration associated with it.
Duration: 5-10 minutes; 0.25 seconds; 3-4 times per second; 25 minutes.
A) The amount of time it takes for the brain to re-focus on a task after a distraction.
B) The minimum amount of time required for the brain to switch from one task to another.
C) The rate at which the perception-action loop occurs, which is the basis of our nervous system’s functioning and corresponds to the number of decisions made by the brain per second.
D) The duration of the micro-objectives that it is recommended to set to maximize our attention in a task.
3. Which of the following statements is incorrect?
A) A young child’s brain is like a “blank page”.
B) A baby can intuitively tell the difference between two or a dozen objects.
C) Once one learning process is automated, the brain is free to move on to the next.
D) For optimal results in lesson repetition, study in a concentrated manner over short periods of time at spaced intervals.
E) We could consciously memorize only 4 or 5 elements.
4. True or false? We could efficiently accomplish more than two tasks simultaneously but under certain conditions.
5. Select the correct term to complete each of the following statements about brain imaging.
Terms: grey matter; connectivity; connections; new learning
Using a type of MRI called “Diffusion MRI”, Denis Le Bihan developed in the years 1990-2000 an image analysis program to map the ________ of the brain. This method has the particularity of calculating the micro-movements of water molecules present in the nerve fibres of the brain, the diffusion of water being slower when it is perpendicular to the direction of the nerve fibres.
Remember that these nerve fibres, also called axons, form the white matter of the brain that connects different areas ________, and that the brain is nearly 80% water! Le Bihan’s image analysis program reconstructs the path of axons in three dimensions from the images it makes of them in several directions. At present, this is the only existing way to visualize the spatial arrangement of brain nerve fibres and all the ________ between the different regions of the human brain.
This type of MRI has been used in a recent study that revealed that, contrary to what was thought, ________ can leave its trace in the cortex very quickly, after as little as an hour.
