Why is visual search research important?

Visual search, a vital task for humans and animals, has also become a common and important tool for studying many topics central to active vision and cognition ranging from spatial vision, attention, and oculomotor control to memory, decision making, and rewards.

How do humans conduct a visual search?

In visual search tasks, people are asked to find a visual stimulus amongst other visual stimuli (distracters). In a visual search experiment, a target is the item that you need to find. A distracter or distractor is an item that you are not looking for, and which distracts you from finding the target.

What variables affect a visual search?

It is guided to the most promising items and locations by five factors discussed here: bottom-up salience, top-down feature guidance, scene structure and meaning, the pre- vious history of search over timescales ranging from milliseconds to years, and the relative value of the targets and distractors.

What is a visual search?

Visual search is a goal oriented activity that occurs regularly in daily life and involves the active scanning of the environment in order to locate a particular target among irrelevant non-targets, or distractors.

Non-target items (distractors) are often similar to the target stimulus excepet in a single dimension (e.g., color or orientation).

How is the ease of visual search related to attention?

The ease of search depends chiefly on how distinguishable the target of search is from the background. For instance, it is hard to find a memo on a desktop cluttered with paper. The task becomes much easier if the memo is a different color than all the other pieces of paper on the desktop. Attention can also improve visual search.

How is SDT used in the search paradigm?

SDT has successfully predicted detection and discrimination in a search paradigm, without additional assumptions about limited-capacity. Instead of a two-stage process with a parallel, unlimited-capacity front end, followed by a limited-capacity attention stage, they have proposed a parallel stage followed by a simple decision rule.

When do you use an attention getter in a speech?

An attention-getter is the device a speaker uses at the beginning of a speech to capture an audience’s interest and make them interested in the speech’s topic.
