A new analysis by University of Michigan researchers found that Olympic timing procedures don't accurately detect false starts by female sprinters, with some being able to anticipate the gun by up to 20 milliseconds. The researchers recommend lowering the force threshold for females to ensure fair racing.
Researchers at Stanford University School of Engineering used new measurement technologies and analytical mathematics to study the neurological explanations for movement planning. They found that neural activity varies depending on direction, distance, and speed of a pending movement, departing from previous theories.
A new study uses advanced analysis to predict reaction time by assessing neural firing rates in the brain. The research found that the degree of neural activity advancement at the 'go' cue significantly affects reaction time.
A study by Stanford researchers found that extended sleep improved athletic performance in collegiate basketball players, with significant improvements in shooting accuracy and sprint times. The study involved 11 healthy students who slept for an average of nearly 8.5 hours per night during the period of sleep extension.
Researchers at the University of Missouri found that women's engagement with news stories is not linked to writing style. Instead, they suggest that women may be less interested in crime and negative stories. The study used secondary task reaction times to compare participants' reactions to inverted pyramid and chronological narrative ...
Researchers found a rare eye movement pattern more common in healthy Chinese individuals than in British participants, challenging the assumption that this pattern is only indicative of underlying neurological issues. This discovery could indicate subtle cultural or genetic influences on brain function, warranting further investigation.
A new study published in the journal Addiction found that energy drinks do not offset the sedating effects of alcohol and do not improve sustained attention or reaction times. The study suggests that public education and warning labels should be considered regarding the safety of caffeinated alcoholic beverages.
Researchers warn that using a cell phone while driving can lead to relationship problems due to impaired attention and divided focus. This includes misunderstandings, hurt feelings, and conflict, as conversations are affected by delayed reactions and lack of nonverbal cues.
Researchers developed a simple and inexpensive device to measure reaction time, which showed slower reaction times after concussions. The test was found to be effective in determining readiness to return to play for Division I college athletes.
People with generalized anxiety disorder have abnormalities in brain emotion regulation, affecting response to negative stimuli. This study's findings may lead to more accurate diagnosis and effective treatment options.
A new synthetic method creates longer polymer chains, increasing current density in plastic solar cells. The reduced reaction time cuts production time by nearly 50%, making it easier to optimize chemical structure and reduce manufacturing costs.
Researchers at the University of Alberta found that sprinters closest to the starter pistol had significantly lower reaction times than those farther away. The study suggests that procedures used in Olympic sprint events may give runners closer to the starter an advantage.
A new test measures subjects' accuracy and reaction times under distractions, filtering out easily distracted candidates. The test correlates with the 'Cognitive Failures Questionnaire', providing an objective assessment of distractibility.
A new study found that medical residents who worked within the mandated 80-hour per week limit still experienced severe sleepiness, affecting their judgment and concentration. The researchers assessed objective and subjective sleepiness using multiple tests and found significant abnormalities on post-call days.
A study found that reaction time slows down during the night and reaches its lowest point in the early morning, affecting cognitive processing stages. The central-slowing hypothesis suggests that this slowdown contributes to impaired driving performance and increased risk of traffic accidents in the early morning.
Researchers found that combining alcohol with energy drinks like Red Bull significantly reduced perceived symptoms of impairment, including fatigue and dizziness. However, objective measures of motor coordination and reaction time remained impaired, highlighting the need for caution when consuming both substances.
A new study found that performing even simple tasks while driving slows down reaction times, demonstrating the psychological-refractory period effect in real-world conditions. The research involved a car simulator and showed participants brake more slowly when easy tasks were presented simultaneously or before brake lights.
A new study found that faster reaction times were associated with longer life expectancy than higher IQ scores. The research built on earlier studies showing a link between lower IQs and early mortality. The study of middle-aged subjects suggested that processing information efficiency may be a key factor in predicting life span.
A study found that prenatal alcohol exposure can impair reaction times, particularly when processing multiple signals. Children with prenatal alcohol exposure showed slower premotor and motor reaction times, indicating difficulties in both central and peripheral processes involved in information processing and action planning.
Researchers at UF found that combining therapies with mild electrical stimulation and motion training to both arms improved motor recovery in people with chronic weakness and partial paralysis. Participants regained significantly more motion, reaction times, and sustained muscle contractions.
Researchers found that a therapy combining electrical stimulation with bilateral movement significantly improved motor skills in stroke patients compared to unilateral movement or physical therapy alone. The study suggests that involving the unaffected limb can help restore function and create new neural pathways.
Research in Occupational and Environmental Medicine shows that prolonged wakefulness impairs reaction times, accuracy, coordination, and attention span, similar to levels of alcohol intoxication. The effects are thought to be cumulative and pose a serious risk to safety, particularly in transportation settings.
A study published in Occupational and Environmental Medicine found that prolonged wakefulness impairs cognitive performance similarly to moderate alcohol consumption. The researchers tested 39 adults who worked in transportation, finding reaction times slowed by up to 50% after 17-19 hours of waking.
