Perceptual learning occurs through sensory interaction with the environment as well as through practice in performing specific sensory tasks.
Although it did not rule out the involvement of high-level cognitive processes in perceptual learning, the discovery prompted researchers to focus on simple sensory tasks and stimuli, which provide basic information about the changes that are occurring within a perceptual system as learning is taking place.
Especially composites with integrated piezoceramic transducers for sensory tasks such as condition or structural health monitoring are gaining importance.
Now, new research suggests the loss of certain types of cognitive skills with age may stem from problems with basic sensory tasks, such as making quick judgments based on visual information.
In conclusion, occipital activation during Braille reading and discrimination tasks is not due to plasticity of sensory or motor function; pure motor or sensory tasks do not lead to an activation of striate cortex.
Performance on most sensory tasks improves with practice.

A group of 263 children, aged 8 to 12 years, underwent MRI to quantify regional brain volumes, tissue composition, myelination, cortical thickness, neural tract architecture, membrane metabolites, functional connectivity in major neural networks and activation/deactivation dynamics during a sensory task.
Moreover, such studies did not focus on perceptual learning as the result of extensive practice in a sensory task.
Since it is difficult to make birds sit absolutely still during a sensory task and obviously impossible during behavioral tasks, general movement-associated activation may distract experimenters' attention from other types of activation.
The sensory task of assessing brightness (or indeed lightness) has similarities with that of measuring environmental irradiance for the accessory visual functions with which ipRGCs have heretofore been associated.
The idea, which goes back to Berkley's (1709/1963) proposition that touch calibrates vision, is that the more 'robust and accurate' sense for a particular sensory task (not necessarily more precise) calibrates the other: a deficit in the more accurate 'calibrating' sense should also impact on the system it should calibrate.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
