The role of a vivid and challenging personal vision in goal hierarchies.

This study examines personal vision and its role in human motivation. It examines the concept of personal vision within goal hierarchies, describes the elements that constitute goal hierarchies, and examines the effect of students' compelling personal vision on the quality of proximal goals. Asking participants to describe their expected or compelling personal vision did not influence the difficulty and vividness of such vision.

Effect of age on horizontal eye movement latency.

Reaction time to initiate an eye movement to a target which suddenly appeared 2.8 degrees from fixation was measured for older and younger adults. Healthy men and women were tested in a series of trials; on one-half of these trials prior knowledge of the target's location was given (simple reaction time), whereas on the remaining trials the target could appear to left or right of fixation with equal probability (choice reaction time).
