The computer – brain analogy
A computer works much like the human
brain. Information is loaded and stored on the computer’s hard drive in
the form of software programs and information files, such as say, an Excel
document. This information (software and files) is
retrieved and processed by the computer’s Central Processing Unit (CPU)
to provide an output or solution, much like the visual at the bottom of
this page.
A computer's capability is determined by the capacity of its hardware - size of its hard drive, and the power of its CPU. We can loosely think of cognitive
capability in the same way. It is the capacity of our neural hardware –
the brain – to acquire, learn, store, and process information, skills,
knowledge, experiences which we collectively refer to as competencies, AND the capacity to engage in cognitive processes such as the ones we listed earlier to solve problems.
The power of the human “CPU and hard drive” will determine:
The extent to which a person can populate his brain with skills, knowledge, competencies and experience;
The effectiveness with which he can utilise the cognitive processes listed above;
And very importantly his ability to take on problem solving challenges which are new or unfamiliar.
It is critical therefore to ensure that a candidate or employee’s “computer hardware” is at least sufficient to deal with the problem-solving demands of his job.
