All Play Takes Place in Temporary Worlds

All play moves and has its being within a play-ground marked off beforehand either materially or ideally, deliberately or as a matter of course…. The arena, the card-table, the magic circle, the temple, the stage, the screen, the tennis court, the court of justice, etc., are all in form and function play-grounds, i.e., forbidden spots, isolated, hedged round, hallowed, within which special rules obtain. All are temporary worlds within the ordinary world, dedicated to the performance of an a...

 Alternative Reason for Age-Related Cognitive Decline

As adults age, their performance on many psychometric tests changes systematically, a finding that is widely taken to reveal that cognitive information-processing capacities decline across adulthood. Contrary to this, we suggest that older adults'; changing performance reflects memory search demands, which escalate as experience grows. A series of simulations show how the performance patterns observed across adulthood emerge naturally in learning models as they acquire knowledge. The simulati...

 Directing Focus

When psychologist Peter Gollwitzer tried to determine how to enable people to set goals and engage in goal-directed behavior as effectively as possible, he found that several things helped improve focus and performance: (1) thinking ahead, or viewing the situation as just one moment on a larger, longer timeline and being able to identify it as just one point to get past in order to reach a better future point; (2) being specific and setting specific goals, or defining your end point as discre...

 Science is More Than Lone Geniuses

The progress of science depends less than is usually believed on the efforts and performance of the individual genius ... many important discoveries have been made by men of ordinary talents, simply because chance had made them, at the proper time and in the proper place and circumstances, recipients of a body of doctrines, facts and techniques that rendered almost inevitable the recognition of an important phenomenon. It is surprising that some historian has not taken malicious pleasure in w...

 Can Social Networking Change the Human Brain

Consider, for example, the fact that the size of military units has not changed materially in thousands of years, even though our communication technology (from signal fires to telegraphy to radio to radar) has. The basic unit in the Roman army (the “maniple”) was composed of 120-130 men, and the size of the analogous unit in modern armies (the company) is still about the same. The fact that effective human group size has not changed very substantially — even though communication techno...
