Cognitive skills, also called cognitive functions, cognitive abilities or cognitive capacities, are brain-based skills which are needed in acquisition of knowledge, manipulation of information and reasoning. They have more to do with the mechanisms of how people learn, remember, solve problems and pay attention, rather than with actual knowledge. Cognitive skills or functions encompass the domains of

, are autonomous modules, or to what extent the functions depend on each other. Research evidence points towards a middle position, and it is now generally accepted that there is ''a degree'' of modularity in aspects of brain organisation. In other words, cognitive skills or functions are specialised, but they also overlap or interact with each other. Deductive reasoning, on the other hand, has been shown to be related to either visual or linguistic processing, depending on the task; although there are also aspects that differ from them. All in all, research evidence does not provide strong support for classical models of cognitive psychology.

Cognitive functioning

Cognitive functioning refers to a person's

Multiple sclerosis (MS), for example, can eventually cause memory loss, an inability to grasp new concepts or information, and depleted verbal fluency. Humans generally have a high capacity for cognitive functioning once born, so almost every person is capable of learning or remembering.

In such tests, patients may be asked a series of questions, or to perform tasks, with each measuring a cognitive skill, such as level of consciousness, memory, awareness, problem-solving, motor skills, analytical abilities, or other similar concepts.
