effect of distraction on reaction time, with special reference to practice and the transfer of training

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Briefly stated, the problem concerns the effect of distraction on reaction time, and the effect of practise in dealing with dis tractions. Other subordinate problems will be treated in their proper sequence. A statement of these minor problems is made on page 26. Reaction experiments were used as the basis of this investiga tion, as the processes involved in the reaction experience are fundamental to behavior in its complexer forms.
