Visual search

Rachael Barnes February 7th, 2016 Dr. Queen Visual Search Lab Introduction Jeremy Wolfe is a psychologist who was particularly interested studying visual attention and visual search. The term “visual search” is used to describe the action of using one’s visual modality to identify an object given to you. Wolfe (2011) posed the question “how you find what you are looking for in a visual world filled with these things that you are not looking for?” (p.1). When it comes to visual search we struggle to find objects that are right in front of our eyes. This becomes a problem when people are tasked with important jobs requiring them to identify potential dangers directly in front of them. As Wolfe (2011) pointed out detecting cancer signs and…

A visual search experiment is an experiment in which an individual's reaction time is tested when finding a visual cue, like a green circle, and determining whether the visual cue is there or not. In the visual field, there also are other objects, called distractors, that aren't the desired visual cue. A subject is tested through two different techniques called a feature search and a conjunctive search. In a feature search, the visual cue would be shown, or possibly not shown, on the screen with…

Participants have been asked to respond to the nearly “life-sized” video stimulation with a motor action of shooting, passing or dribbling the ball. The results revealed that experts had significantly quicker reaction times, higher accuracy rate of their decisions and used the time available for search of the information more efficiently than novice. Eye movement date showed that experts demonstrated fewer long time fixations on selected area of the display which made their visual search far…

(Goldstein, 2015). Binding has been tested using the visual search experiment as it proves useful when studying a conjunctive search. Goldstein (2015) suggests that visual search is an everyday process where we look for a certain object among several others. The visual search experiment has two types of searches, feature and conjunctive. Nordfang & Wolfe (2014) suggests conjunctive searches share similarities to the target such as colour, size or shape. In contrast feature searches are parallel…

95% confidence that his PRI score lies between 96 and 108. This index is composed of three subtests, Block Design (SS=12), (VP=7), (MR=12). Given the similar moderate scoring among the subtests, the PRI should be considered unitary and interpretable. The PRI should be considered an overall indicator of fluid reasoning in the perceptual domain with tasks that assess nonverbal concept formation, visual perception and organization, simultaneous processing, and visual-motor coordination, learning,…

learning style assessments feature three or four possible learning styles, which are auditory, tactile, visual, and written styles. Like me, many people have more than one dominant style. VARK explains that aural learners relate well to spoken material such as…

and critical theory. The array of courses I have taken on the art and literature of the early modern period as well as a semester spent studying abroad in Rome have only fueled my attachment to the art and culture of this era. After participating during the fall of my senior year in the roundtable discussion “Art History and Visual Culture: Limits and Horizons,” as part of the first annual Northwest Five Consortium Visual Culture Colloquium hosted at Willamette University, I additionally…

The Police and Criminal Evidence Act 1984 (PACE) is the core framework that is provided to ensure that the powers of the police are used correctly and that it protects and safeguards individuals that come into contact with the police. There are five major sections that it is in respect of: stop and search, arrest, detention, investigation and interviewing. Stop and search is allowed when there are reasonable ground to believe that the person or vehicle contains drugs, offensive weapons…

acoustic experiences as well. The film scholar, Thomas Elsaesser, makes various points in his book “Film Theory” describing several ways in which we can experience the film as a spectator. A particular type of metaphor that stood out to me that Elsaesser mentioned was cinema as a visual experience, more precisely cinema as eye or as a look and gaze. All of Elsaesser’s ideas can be related to and exemplified in the mystery/thriller…

believed to have begun with the foundation of documentary film. In 1922, filmmaker Robert Flaherty released the first documentary, Nanook of the North. This narrative documentary film essentially led to generic conventions that documentaries then developed over decades (Fisher 13 September), despite its portrayal of its subjects as spectacle. Soon, film had also found its way into the anthropological world. Anthropologist Margaret Mead and her partner Gregory Bateson applied the camera as a…
