Essay Cove

  1. When it comes to the principle of Visual Search, attention is most certainly involved (see Textbook pages 107-113) – especially when searching for anything of potential value, whether for positive {like searching for a treasured item amidst an array of unimportant personal items} OR for negative {like, in airport security, when screeners search an x-ray computer screen for a dangerous item amidst an array of unimportant items (See Textbook pages 108-109)}.
