Attention, Perception, and Consciousness: Examine Four Discrete Areas

Attention, Perception, and Consciousness as They Relate to Imaging Techniques, Theories of Attention, Size Judgments, and the Ponzo and Muller-Lyer Illusions

This paper presents and discusses research obtained from an extensive literature review that was conducted in order to examine four discrete areas of attention, perception and consciousness. The areas that were examined were related to imaging techniques, theories of attention, perceptual judgments of size, and to the Ponzo and Muller-Lyer illusions. The focus of each area examined was a response to a stipulated question or statement and is presented in relation to each questio/statement. The paper also includes an annotated outline of the material discussed in each area. The outline identifies where supporting references are integrated into the final paper.

This section of the paper provides an overview of the research material covered, noting that the material discussed is in four discrete areas of attention, perception and consciousness. Each area is listed as imaging techniques, theories of attention, perceptual judgments of size, and the Ponzo and Muller-Lyer illusions.

B. Research Findings for Questions and Statements on Imagining Techniques, Theories of Attention, Perceptual Judgements of Size, and the Ponzo and Muller-Lyer Illusions.

, 2006). As to potential hazards to physical health, as with x-ray imaging, potential hazards of the CT scan include over-exposure to radiation (Carver & Carver, 2006). Indeed, the dose of radiation received by a patient during a typical CT procedure is generally much larger than the radiation doses associated with most conventional x-ray imaging procedures (Van Gelderen, 2004). Leondes (2007) states that in the future, CT scanning technology can be expected to see a strong improvement in the technology. First, it can be expected that the imaging will be upgraded and improved, e.g., the Cone Beam CT scan. Second, it can be expected that in the future the x-ray exposure risk will be reduced. The third often-used imaging technique is magnetic resonance imaging or MRI which does not use radiation (Leondes, 2007). Rather, the MRI involves the use of magnetic waves and spinning protons, which are converted into images (Bushberg, Siebert, Leidholdt, & Boone, 2001). According to Huettel, Song and McCarthy (2004), common uses for the MRI include precise and clear pictures of soft-tissue structures, the diagnosis of injuries (especially sports injuries), the identification of very small tears or injuries, and the examination, i
