Brain-as-Computer Discourses

Focus

Interpreting learners and learning in terms of computers and computer functioning

Principal Metaphors

  • Knowledge is … information
  • Knowing is … using information
  • Learner is … an information processor
  • Learning is … inputting (and associated computer-based notions, such as processing, storing, and retrieving)
  • Teaching is … transmission (of information)

Originated

1950s

Synopsis

There is a long history of interpreting learning in terms of the latest technologies. Examples include writing on a tablet, taking photographs and films, and making connections on a telephone switchboard. Brain-as-Computer Discourses represent an uncritical continuation of this trend, through which knowledge is reduced to information and learning is cast as inputting and manipulating that information. Most Brain-as-Computer Discourses assume the following subdiscourse:
  • Sandwich Model of Cognition (Susan Hurley, 1990s) – a metaphor used to highlight the tendency of most Brain-as-Computer Discourses to assume a separation of perception (input) and action (output), thus positioning cognition between them as the process of converting perceptions into actions.

Commentary

Brain-as-Computer Discourses represent a reversal of a prior metaphor that “computers are brains.” Brain-as-Computer Discourses were in part propelled by the fact that early computers proved to be very effective at tasks that their designers found difficult – namely, highly repetitive ones based on pure logic. Indeed, early successes on complicated mathematical tasks prompted some developers to predict, with confidence, that “electronic brains” would soon surpass their flesh-based counterparts. In spite of their popularity, neither metaphor (i.e., “brains are computers” and “computers are brains”) is tenable. Flatly asserted, brains are not digital computers.

Subdiscourses:

  • Sandwich Model of Cognition - Sandwich Model of Cognition (Susan Hurley, 1990s) – a metaphor used to highlight the tendency of most Brain-as-Computer Discourses to assume a separation of perception (input) and action (output), thus positioning cognition between them as the process of converting perceptions into actions.
