الصفحة 129 - Application of modern psychological principles to educational subjects ; the psychological methods as modified for school use ; outlines of the psychology of touch, its use in education ; motor abilities, accuracy of movement, fundamental principles of writing and drawing ; hearing, training the ear...
الصفحة 82 - The curves for reaction time gave the most positive results showing that the brighter the child the more quickly he is able to act. In discrimination the same relation is true but to a less degree. ... Of time memory it may be said in general that the brighter the child the more accurate his sense of time.
الصفحة 112 - The general conclusion seems to be that fencing does not develop mental quickness more than scientific pursuits, but it does develop to a high degree the rapidity of executing movements. It would be important to determine if this holds good of the other sports and exercises, or if some of them are especially adapted to training mental quickness.

الصفحة 69 - The laboratory consists of fifteen rooms, three of which, including an "isolated" room, are given over entirely to research. The isolated room is a small room built inside of -another room ; four springs of rubber and felt are the only points in which it comes in contact with the outer walls. The space between the walls is filled with sawdust as in an ice-box. The room is thus proof against sound and light, and, according to Science, affords an opportunity of making more accurate experiments on the...
الصفحة 88 - ... the pendulum starts its swing, soon reaching a light pointer held in position by a delicate spring, which it carries along. At the exact moment the pendulum takes up the pointer it presses a catch which releases the mechanism beneath the base; this mechanism causee a shutter to drop, thus covering an opening in a metal plate at the back of the chronoscope.
الصفحة 30 - ... difference was detected between the times of reactions in silence and those made while listening to the steady sound of a tuning-fork making 250 vibrations per second. 5. When the intermittent sound of a metronome was substituted for that of the fork, the reaction-time was lengthened.
الصفحة 89 - The person to be experimented upon is seated at the back; a curtain keeps him from seeing anything except the metal plate with the covered opening. He presses a rubber button as soon as he sees the shutter move, and a horizontal bar is released running behind the scale. The pointer swings between this bar and the scale, and is consequently stopped when the bar snaps against the scale. The pointer starts to move as soon as the shutter starts to fall, and consequently any time that elapses thereafter...
الصفحة 48 - Ability to distinguish different shades of the same color increases with age. As a rule, at 7 marked irregularities occur in all the curves which require mental action or discrimination.
الصفحة 58 - The average boy . . . taps 29.4 times in five seconds, the average girl taps 26.9 times, thus tapping 8.5 per cent. slower than boys. The average boy . . . loses 18.1 per cent. by fatigue, the average girl loses 16.6. In other words the boys lose 1.5 per cent. more by fatigue and yet tap 8.5 per cent. faster. This leaves the balance greatly in favor of boys.
