Attention Deployment During Memorizing And Executing Complex Instructions., Jens K. Apel, Gavin F. Revie, Angelo Cangelosi, Rob Ellis, Jeremy Goslin, Martin H. Fischer

School of Psychology

We investigated the mental rehearsal of complex action instructions by recording spontaneous eye movements of healthy adults as they looked at objects on a monitor. Participants heard consecutive instructions, each of the form "move [object] to [location]". Instructions were only to be executed after a go signal, by manipulating all objects successively with a mouse. Participants re-inspected previously mentioned objects already while listening to further instructions. This rehearsal behavior broke down after 4 instructions, coincident with participants' instruction span, as determined from subsequent execution accuracy. These results suggest that spontaneous eye movements while listening to instructions predict their successful execution.

Macular Pigment: Practical Implications For Optometric Practice In Preventative Health Care And Visual Performance Enhancement, Grainne Scanlon

Masters

The macula is a specialised part of the retina responsible for detailed central and colour vision. The carotenoids, lutein, zeaxanthin and meso-zeaxanthin are uniquely concentrated in the inner and central layers of the primate macula, where they are known as macular pigment (MP). It has been shown that MP is entirely of dietary origin and that lutein and zeaxanthin levels in serum, diet and retina correlate. Age-Related Macular Degeneration (AMD) is a disease of the macula and results in loss of central vision. MP, because of its optical filtration and antioxidant properties, may have an important role in the prevention …

Mind Perception: Real But Not Artificial Faces Sustain Neural Activity Beyond The N170/Vpp, Thalia Wheatley, Anna Weinberg, Christine Looser, Tim Moran, Greg Hajcak

Dartmouth Scholarship

Faces are visual objects that hold special significance as the icons of other minds. Previous researchers using event-related potentials (ERPs) have found that faces are uniquely associated with an increased N170/vertex positive potential (VPP) and a more sustained frontal positivity. Here, we examined the processing of faces as objects vs. faces as cues to minds by contrasting images of faces possessing minds (human faces), faces lacking minds (doll faces), and non-face objects (i.e., clocks). Although both doll and human faces were associated with an increased N170/VPP from 175–200 ms following stimulus onset, only human faces were associated with a sustained …

Drawing A Line In The Sand: Copyright Law And New Museums, Megan M. Carpenter

Law Faculty Scholarship

Over the last twenty years, audience attendance at museums, galleries, and performing arts institutions in the United States has decreased dramatically. Major museums and galleries are considering ways to add engaging and meaningful value to the user experience with technology, from incorporating user-generated content to creating multimedia installations billed as “collaborative” works.

In 2010, the Dallas Museum of Art’s Coastlines: Images of Land and Sea exhibition featured landscapes from 1850 to the present, as well as a sound installation composed by students and faculty in the Arts and Technology program at the University of Texas at Dallas, which played on …

Lipid Pathway Alterations In Parkinson's Disease Primary Visual Cortex, Danni Cheng, Andrew M. Jenner, Guanghou Shui, Wei Fun Cheong, Todd W. Mitchell, Jessica Nealon, Woojin Scott Kim, H Mccann, Markus R. Wenk, Glenda Halliday, Brett Garner

Background: We present a lipidomics analysis of human Parkinson’s disease tissues. We have focused on the primary visual cortex, a region that is devoid of pathological changes and Lewy bodies; and two additional regions, the amygdala and anterior cingulate cortex which contain Lewy bodies at different disease stages but do not have as severe degeneration as the substantia nigra. Methodology/Principal Findings: Using liquid chromatography mass spectrometry lipidomics techniques for an initial screen of 200 lipid species, significant changes in 79 sphingolipid, glycerophospholipid and cholesterol species were detected in the visual cortex of Parkinson’s disease patients (n = 10) compared to …

What Is The Effect Of Real Versus Augmented Models For The Advancement Of Spatial Ability Based On Haptic Or Visual Learning Style Of Entry-Level Engineering Graphics Students?, Katie L. Huffman

Department of Computer Graphics Technology Degree Theses

This research study conducted during the Fall Semester of 2011 at Purdue University compared the use of augmented reality and real blocks instructional methods, for advancing spatial abilities in students of different learning styles (visual/haptic). This study implemented augmented reality and real models as visualization aids for first year engineering students enrolled in an entry level engineering graphics course. This thesis presents the significance of this research study, the research methodology, and the statistical findings. The results of the study conclude that there is no significant interaction between learning style of visual or haptic and instructional method of augmented reality …
