Classic Gestalt image
| A vase or two faces?This is the iconographic parallel of semiotic concerns about discourse. (I can't believe I just wrote that! Pretentious, moi?) Even so, I'm afraid it's (probably) accurate. It's easy to see one or the other: almost impossible to see neither. The classic Gestalt phenomenon is that of figure versus ground. Which is the image and which the background? And how does the brain decide? |

| What is it (2)? |
It is clear that some kind of cognitive re-structuring has taken place, which may then become apparent in behaviour, but seemingly precedes that behaviour. Someone has "understood" differently, so that their capacity for potential action has changed, even if that action or behaviour is not immediately manifest. Exactly what is going on in the brain we do not yet know, but there have been considerable advances in recent years (even since the first edition of this site in 2002), and neuroscience is a hot topic nowadays. (I am continuing to search for web resources in this field which are both reliable and accessible. Few are both. In the meantime see Zull, 2002 and Johnson, 2005)
The importance of the theory for real-world learning is the attention which it draws to wholes (and incidentally to problem-solving as a part of learning). Whereas behaviourism concentrates on breaking down a task into parts and how each is learned individually and incrementally, Gestalt acknowledges the “knack” element. It thus underpins all the cognitivist theories.
A "knack" is a psychomotor equivalent of cognitive "insight": the best example is probably learning to ride a bicycle. The learning "curve" (where x=time and y=skill) is more like a single step. The learning happens in a few moments, and is permanent—although it may have taken a long time to get to that step with little seeming progress.
It also contributes to an account of some of the difficulties people have with learning: Gestalten (similar to schemata, in a different discourse), once formed, are not easily dislodged or replaced.
