Through its numerous outreach and community-based programs, the Creighton University School of Dentistry provides much-needed care to underserved populations, treating nearly 27,000 patients annually. Page 16.
WHAT MAKES TEACHING AT CREIGHTON SPECIAL?
Eileen Wirth, Ph.D., chair of the Department of Journalism, Media & Computing, who will be retiring at the end of the semester, reflects on the memorable connections formed between faculty members and students at Creighton. Page 24.
AN INSIDE LOOK AT EMOTIONS
What do our emotions tell us about ourselves — as individuals and cultures? Where do emotions come from? How do emotions affect the brain? Creighton faculty shed light on these questions and more while exploring the complex and mysterious world of our emotions. Page 28.
THE BUSINESS OF DOING GOOD
From teaching companies how to become more ethically responsible to planting 150-year-old corn seeds to help Native groups market food products to the general public, the Heider College of Business has created innovative ways of teaching business practices. Page 34.
STRESS!
Life can be stressful and chronic stress can be detrimental to our health — even deadly. How do our minds and bodies respond to stress, and how can we better manage that response? We turn to Creighton experts and an alumnus conducting cutting-edge research in this area for answers. Page 38.13
Lives cut short: Insights from the osteological and palaeopathological analysis of the Ballyhanna juveniles
No full textAttention during sequences of saccades along marked and memorized paths
No full textAbstractNatural scenes are explored by combinations of saccadic eye movements and shifts of attention. The mechanisms that coordinate attention and saccades during ordinary viewing are not well understood because studies linking saccades and attention have focused mainly on single saccades made in isolation. This study used an orientation discrimination task to examine attention during sequences of saccades made through an array of targets and distractors. Perceptual measures showed that attention was distributed along saccadic paths when the paths were marked by color cues. When paths were followed from memory, attention rarely spread beyond the goal of the upcoming saccade. These different distributions of attention suggest the involvement of separate processes of attentional control during saccadic planning, one triggered by top-down selection of the saccadic target, and the other by activation linked to visual mechanisms not tied directly to saccadic planning. The concurrent activity of both processes extends the effective attentional field without compromising the accuracy, precision, or timing of saccades
The relationship between spatial pooling and attention in saccadic and perceptual tasks
No full textAbstractSaccades aimed at spatially extended targets land reliably at central locations determined by pooling information across the target shape [Melcher, D., & Kowler, E. (1999). Shape, surfaces and saccades. Vision Research, 39, 2929–2946; Vishwanath, D., & Kowler, E. (2003). Localization of shapes: Eye movements and perception compared. Vision Research, 43, 1637–1653]. Previous findings of saccadic errors when attempting to look at a target in the midst of distractors encouraged suggestions that pooling occurs indiscriminately, with little or no influence of a selective filter to eliminate the influence of nearby distractors. To determine the effectiveness of filtering, saccadic localization was studied for saccades made to a set of target elements (discs) interleaved with an equivalent set of distractors of a different color. With such interleaved elements, selection and spatial pooling are constrained to occur over the same spatial region. The results showed that filtering was effective and saccadic landing position was determined mainly by the target elements. Concurrent perceptual judgments made about the same stimuli (estimating the mean size of either target or distractor discs) showed better performance for the target discs than distractors, confirming that perceptual attention was allocated to the set of target elements. These results: (1) support the role of attention in setting the input to the spatial pooling process that guides saccades to spatially extended targets, and (2) show that perceptual judgments of mean value, often thought to impose modest attentional demands, are not immune to the constraints of this pre-saccadic filter
