The number of health care educational institutions/organizations adopting implicit bias training is growing. Our systematic review of 77 studies (published 1 January 2003 through 21 September 2022) investigated how implicit bias training in health care is designed/delivered and whether gaps in knowledge translation compromised the reliability and validity of the training. The primary training target was race/ethnicity (49.3%); trainings commonly lack specificity on addressing implicit prejudice or stereotyping (67.5%). They involved a combination of hands-on and didactic approaches, lasting an average of 343.15 min, often delivered in a single day (53.2%). Trainings also exhibit translational gaps, diverging from current literature (10 to 67.5%), and lack internal (99.9%), face (93.5%), and external (100%) validity. Implicit bias trainings in health care are characterized by bias in methodological quality and translational gaps, potentially compromising their impacts.

Purpose: Listening in noise is an everyday activity and poses a challenge for many people. To improve the ability to understand speech in noise, a computerized auditory rehabilitation game was developed. In Trivia Game players are challenged to answer trivia questions spoken aloud. As players progress through the game, the level of background noise increases. A study using Trivia Game was conducted as a proof-of-concept investigation in healthy participants., Method: College students with normal hearing were randomly assigned to a control (n = 13) or a treatment (n = 14) group. Treatment participants played Trivia Game 12 times over a 4-week period. All participants completed objective (auditory-only and audiovisual formats) and subjective listening in noise measures at baseline and 4 weeks later., Result: There were no statistical differences between the groups at baseline. At post-test, the treatment group significantly improved their overall speech understanding in noise in the audiovisual condition and reported significant benefits in their functional listening abilities., Conclusion: Playing Trivia Game improved speech understanding in noise in healthy listeners. Significant findings for the audiovisual condition suggest that participants improved face-reading abilities. Trivia Game may be a platform for investigating changes in speech understanding in individuals with sensory, linguistic and cognitive impairments.

A significant percentage of fatal vehicle crashes involve loss of control (LOC). Electronic stability control (ESC) is an active safety system that detects impending LOC and activates counter-measures that help the driver maintain or re-gain control. To assess the effectiveness of ESC in preventing LOC, an empirical study was conducted on a high-fidelity driving simulator. The ESC systems for two vehicles were incorporated into the simulator's dynamics code which was calibrated to ensure engineering validation. The study utilized three scenarios designed to recreate typical LOC situations, and was designed to assess the effects of ESC presence, vehicle type, scenario, age and gender. A total of 120 research participants completed the study. Results showed a statistically significant reduction in LOC with ESC compared to without ESC (F=52.72, p<0.0001). The study findings of 5% LOC with ESC and 30% without ESC match several epidemiological studies that have analyzed ESC effectiveness on real-world crashes, providing strong support to the use of driving simulation for studying driver behavior. Study conclusions suggest that wide-spread utilization of ESC is likely to reduce traffic fatalities., (Copyright (c) 2009 Elsevier Ltd. All rights reserved.)

First-generation antihistamines are well-known to cause subjective drowsiness. A myriad of studies has also been published that suggest a clear relationship between the use of these drugs and objective performance impairment. Although not all of the tests used in these studies have been validated, the data are fairly consistent, and suggest a difference between earlier (first-generation) sedating antihistamines and the newer (second-generation) nonsedating antihistamines.
