Searchers Switch Tactics Under Increased Mental Load
Effects of mental demands on searchers were examined by controlling tasks complexity and by assessing searchers’ working memory span (WM). The searchers were divided into low and high WM group.

Low-WM searchers performed about ...

متن کاملLoad-carrying capacity of the human cervical spine in compression is increased under a follower load.
STUDY DESIGN An experimental approach was used to test human cadaveric cervical spine specimens. OBJECTIVE To assess the response of the cervical spine to a compressive follower load applied along a path that approximates the tangent to the curve of the cervical spine. SUMMARY OF BACKGROUND DATA The compressive load on the human cervical spine is estimated to range from 120 to 1200 N during...
