Visual Searches

> You probably notice every day that some objects in the environment are
> easier to notice than other objects. For example, workers at sports
> stadiums often wear bright yellow shirts, which are very easy to see. While
> the crowd may blend in together, the workers are prominent and are easy to
> notice when you want a drink or something to eat. In this assignment, you
> will further explore how people engage in visual searches and what features
> of a stimulus make a search easier.
> Think of a time when you had to locate someone in a crowd, such as a
> participant in a parade, a friend in a packed theater, or a runner in a
> marathon. Based on your experience, respond to the following:
>    – Were you successful in locating the person? What strategy did you use?
>    – Did your search make use of the pop-out effect? How? If not, how might
>    using the pop-out effect have resulted in a successful or quicker
> search?
>    – Did you conduct a conjunctive search? If yes, how did the number of
>    distracters and features affect your search?
>    – Using the principles you have read about in this module, how would you
>    make material in a long e-mail stand out in order to ensure that the
> reader
>    notices it?
> Visual searches are also very important in warnings. Warnings need to stand
> out from their background. The warning must first be noticed, then read and
> understood. For example, a stick figure could be performing an ambiguous
> action and have an “X” through it. You therefore understand that while you
> are not supposed to perform some action, you do not understand what that
> action actually is.
> Give two examples of a poor warning. Did you understand them? Why did you
> have difficulties with them? What features could be modified to make the
> warnings more effective?
> Write your initial response in 4-5 paragraphs. Apply APA standards to
> citation of sources.
