Objective: Design an optimised auditory azimuth localisation training protocol by: (1) differing the number of training stimuli presentations to determine the highest angular accuracy achieved in the fewest training sessions, (2) evaluating the presence of training transfer from a broadband stimulus to untrained militaryrelevant stimuli and (3) measuring the effect of differing training strategies on localisation accuracy. Design: Two pilot studies of 18 and six subjects, respectively, determined the number of presentations and type of stimuli to be included in a localisation training experiment that evaluated different training strategies. In the pilot studies, participants trained using eight Learning Units (LU) and then tested using untrained stimuli. In the main experiment, 40 participants completed eight LUs using four different learning strategies, with 10 participants randomly assigned to each condition. Sample: All participants were ages 18-42 normal-hearing listeners with thresholds not exceeding 25 dB HL and asymmetry not exceeding 15 dB HL. Results: Transfer of training occurred using three of the four untrained stimuli. The training strategy that resulted in the highest localisation accuracy involved active participation. Conclusions: Training with a broadband stimulus transfers to untrained broadband stimuli. Training involving the active participation strategy resulted in the greatest localisation accuracy.
Introduction
There are vast differences in clinical presentations of melanoma across skin tones. Individuals with darker skin tones tend to have a higher prevalence of advanced-stage melanoma, which correlates with increased mortality. We designed this interactive workshop to increase nursing and medical trainees’ awareness of the epidemiology, prevention, and treatment of melanoma in individuals of darker skin tones.
Methods
The Kern model was used in the design, implementation, and evaluation of the workshop. The 75-minute workshop consisted of a PowerPoint presentation, video-based reflection activities, and case studies. Evaluation consisted of pre- and postworkshop questionnaires. The workshop was implemented two times among 63 nursing students, 11 medical students/residents, and six medical faculty.
Results
Seventy-one participants completed the pre- and postworkshop evaluations. A comparison of pre- and postworkshop responses utilizing the Wilcoxon matched-pair signed rank test showed a statistically significant increase in learners’ confidence to address each learning objective.
Discussion
Through this interactive educational presentation, medical and nursing trainees can gain heightened awareness of melanoma across various skin tones, especially unique presentations in darker skin tones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
