✦ Synopsis

for the workshop, and it conveys a hint of what has yet to be performed by those confronted by this problem of industrial education.

So far as can be judged, the attention of scientific investigators in their recent efforts has been directed chiefly to theories applied to workers upon repetitive tasks, and IO conditions underlying efficiency and economical methods of learning in that field. It is one of the purposes of the learning curves, with which the report is essentially concerned, to determine if with increase of skill, personal differences between individuals tend to disappear or persist.

The curves are also useful in investigating such questions as the most economical length of interval which should be interposed between successive practice periods when a new task is being Iearned.

On this point, MI-. J. M. Blackburn, the author of the report, is of opinion that the task is learned with the fewest number of repetitions if rest periods are introduced, but in a shorter time if the instruction is "massed," although in this latter case greater effort is needed.
