Abstract:

The effect of magnification on a task requiring visual form- comparison was investigated. The critical detail was such as to require close attention, but even in the smallest size was above the acuity threshold. It was found that, for this type of task, speed of performance increased with increasing size up to an intermediate level, and remained constant for increases beyond that level.
