The "Landmark Task" (LT) is a line bisection judgment task that predominantly activates right parietal cortex. The typical version requires observers to judge bisections for horizontal lines that cross their egocentric midline and therefore may depend on spatial attention as well as spatial representation of the line segments. To ask whether the LT is indeed right-lateralized regardless of spatial attention (for which the right hemisphere is known to be important), we examined LT activation in 26 neurologically healthy young adults using vertical (instead of horizontal) stimuli, as compared with a luminance control task that made similar demands on spatial attention. We also varied task difficulty, which is known to affect lateralization in both spatial and language tasks. Despite these changes to the task, we observed right-lateralized parietal activations similar to those reported in other LT studies, both at group level and in individual lateralization indices. We conclude that LT activation is robustly right-lateralized, perhaps uniquely so among commonly-studied spatial tasks. We speculate that the unique properties of the LT reside in its requirement to judge relative magnitudes of the two line segments, rather than in the more general aspects of spatial attention or visual-spatial representation.

Objective Tracheostomy is a common procedure that requires management by a multidisciplinary team of health care providers across a range of surgical and nonsurgical specialties. Nonsurgical health care providers have demonstrated a lack of knowledge and confidence in tracheostomy care, which improve with tracheostomy education programs. However, tracheostomy care is rarely included in preresidency medical education. The purpose of this study is to evaluate the effectiveness of a tracheostomy care video on third-year medical students’ knowledge of and confidence in performing tracheostomy care. Methods Prior to beginning clinical rotations, third-year medical students completed a 10-question tracheostomy care knowledge test (100 points total) and 11-question confidence survey (110 points total). After watching an 18-minute teaching video on tracheostomy care, students repeated the knowledge test and confidence survey. Results An overall 147 medical students completed the educational module. After they watched the tracheostomy education video, their average score on the knowledge test improved from 57.8 to 88.9 out of 100 ( P < .0001), and their average rating in confidence improved from 12.7 to 49.1 out of 110 ( P < .0001). Students rated the helpfulness of the video a 7.4 out of 10. Discussion Medical students’ knowledge of tracheostomy care and confidence in caring for patients with tracheostomies improved after watching the video. Tracheostomy education should be included in early medical education so that future physicians of various specialties can better care for this patient population. Implications for Practice Internet-published videos are an accessible educational resource with great potential application to various topics within otolaryngology, including tracheostomy care.
