Abstract Objective Due to the COVID-19 pandemic, many services attempted to quickly transition to a remote format. A need to incorporate and evaluate a remote delivery of neuropsychological measures arose. TestMyBrain (TMB) from the Many Brains Project has been utilizing teleneuropsychology in research since 2017. Method Volunteer research participants (N = 176, Mage = 29, Medu = 15 years, 64.7% white, 54.2% female, 83.2% right-handed) were administered TMB Simple Reaction Time and Choice Reaction Time subtest as part of a larger battery via zoom. Participants were able to choose between completing these measures using a keyboard, mouse, or a touch screen. There were no significant differences among demographic variables across the different completion methods. Results An ANCOVA indicated there was not a significant difference in simple reaction time across the different response F(2,168) = 0.482, p = 0.618, ηp2 = 0.006. There was however a significant difference in choice reaction time across the different response methods F(2,168) = 11.486, p < 0.001, ηp2 = 0.120. Conclusion Results suggest different response methods maybe suitable for simpler tasks, yet there lacks consistency in response methods for more complex tasks. This medium effect size may have occurred as a result of the lack of sensitivity for devices to detect taps on different portions of the screen as effectively as various keys on a keyboard. Administrators must be aware of the limitations response methods may introduce into results. Limitation to this analysis include limited samples and not controlling for other factors that may potentially influence reaction time such as internet connection. Future research should focus on creating a standardized method for teleneuropsychology administration.

Study Participants

Background: Cycling is a popular recreational and competitive sport with many health benefits but also significant risks, with 85% of recreational cyclists reporting an injury each season. The most common mechanism of injury is through a loss of control of the bicycle, and collisions with other objects. Reaction time and agility in cyclists may contribute to the ability to control a bicycle. Objectives: To evaluate bicycle-specific agility and reaction time in cyclists. Methods: The study was a cross-sectional observational study. Thirty-five cyclists (27 males, eight females) participated in this study. Participants attended a single testing session where they completed a bicycle-specific agility test, and online simple and choice reaction time testing while cycling at three different exercise intensities. Results: There was a significant difference in agility between males and females (p=0.01). There was also a significant difference in choice reaction time between cycling at ‘light’ and ‘very hard’ intensities (p=0.004), and a significant positive relationship between agility and simple reaction time at a ‘hard’ intensity. Discussion: Choice reaction time improved at ‘very hard’ cycling intensity, supporting the theory that increased exercise intensity improves cognitive arousal. This reaction time may be essential as a means to avoid collisions and falls from bicycles. Bicycle-specific agility appears to be related to simple reaction time, but there are no existing validated bicycle-specific agility tests available. The value of the tests undertaken by the authors needs to be assessed further. Conclusion: Choice reaction time was significantly decreased in high intensity cycling compared to cycling at low intensities. Further prospective studies are needed to establish links between reaction times and bicycle-specific agility.

Neuromotor reaction times (simple, choice, and decision) were measured when Thyrotropin-releasing hormone (TRH) was administered intravenously to nine healthy men in a double-blind study. Measurements were made of simple reaction time, choice reaction time, and decision time for each subject at various intervals over a 54-hr. period. Given the observed inherent interaction of the drug with the long time used (54 hr.), most analyses were conducted across separate time epochs. Injected subjects showed inhibition in the normal improvement of simple reaction time (which occurs with practice), and they reduced the time required to make a decision. Choice reaction time, however, remained unchanged across the drug-nondrug experimental conditions.

Time Required

Simple reaction time (SRT) is the minimum time required to respond to a stimulus; it is a measure of processing speed. Our study aimed to determine the variation in visual SRT with time among individuals of the same gender and between genders. We carried out a prospective, parallel group, pilot study involving ten male and ten female medical students aged 18–25 years. After obtaining written informed consent, the participants were familiarized with the procedures, and each completed a single practice session of a computerized visual SRT which was administered using Psychology Experiment Building Language Version 2.0 software. On a predetermined day, the participants completed the exercise at 10 a.m., 1 p.m., and 5 p.m. The results showed no statistically significant difference in SRT based on time of day between genders (χ2(2) = 4.300, p = 0.116 ) as well as within gender (males (χ2(2) = 0.600, p = 0.741 ); females (χ2(2) = 5.000, p = 0.082 ). Our study showed that visual SRT does not change significantly at different times of the day and within and between genders. Intraindividual variations in visual SRT can mask the presence of a small but significant difference; hence, further studies are warranted.

Verbal Messages

It was thought that the physical aspects of auditory stimuli were possibly transmitted via separate pathways from those transmitting the verbal aspects. Three experiments were designed to test this hypothesis. In these experiments subjects had to perform a shadowing task and had to respond simultaneously on response keys to pips superimposed in either ear on verbal messages. The response to these pips was of increasing complexity, in that it was a simple reaction time which was measured in the first experiment, a choice reaction time in the second experiment and a more complex choice reaction time in the third experiment. Subjects were able to perform these tests although the increasing difficulty was reflected in longer reaction times and more errors. The reaction times to the pips presented to the ear which was not being shadowed were slower, and the errors, made to pips in both channels, were “false positives” rather than errors of omission. These results were taken as favouring the hypothesis.

Time Required

Simple reaction time is known to decay as a hyperbolic function of luminance (Piéron's function). An identical relationship has also been demonstrated recently (Pins and Bonnet, 1996 Perception & Psychophysics in press) with different choice-reaction-time tasks. Although mean choice reaction time increased with the complexity of the task, the exponents of the functions relating reaction time (RT) to luminance were found to be equal in each experiment. These results suggest that the task specific time required by the different tasks only adds to the time necessary for luminance processing. In these experiments, the different stimuli presented were easily discriminable. In the present study, we examined the effect of variation in luminance on a more difficult discrimination task involving variation in orientation. Five different luminance levels covering the entire mesopic range were used. In two conditions, tilted lines at nine different angles were used, at a spacing of 2°. In the first condition, the orientations were chosen on both sides of the vertical (the subject responded “left” or “right”); in the second condition, the orientations were on both sides of a line oriented at −40° to the vertical (the subject responded “high” or “low”). The results were compared to those of a second experiment in which only two easily discriminable orientations were used. The results show that RT is greater in the experiments in which nine orientations are used, while the effect of intensity on RT is lower. This effect does not depend on orientation.

The aim of this study was to investigate the effects of agility training on reaction time in fencers. Accordingly, 48 athletes (24 females and 24 males) actively involved in fencing participated in the study. Fencers were divided into two groups as 24 fencers in the Agility Training Group (ATG: 12F, 12M) (aged 11.95 years, sports age 2.54 years, height 159 cm, body weight 48.08 kg and body mass index 18.81 kg/m²) and Conventional Training Group (CTG: 12F, 12M) (aged 12.12 years, sports age 2.20 years, height 156.54 cm, body weight 46.25 kg and body mass index 18.81 kg/m²). There was a statistically significant difference between the pre-test and post-test values in agility, vertical jump, simple reaction time and multiple reaction time tests in the ATG (p<0.05). There was a statistically significant difference between the pre-test and post-test values in agility and vertical jump tests in the CTG (p<0.05). There was a statistically significant difference in the pre-tests between the groups in the simple reaction time test (p<0.05). There was a statistically significant difference in post-tests between the groups in the agility, simple reaction time and multiple reaction time test values (p<0.05). Based on the results of the study, it was found that simple and multiple reaction time could be positively affected by active-reactive agility training applications.

A comparison was made to determine the effect of epilepsy on simple reaction time among 57 school-aged subjects. The subjects were classified intellectually as average, educable mentally retarded, or trainable mentally retarded, and neurologically as epileptic or nonepileptic. Following an explanation of the testing apparatus, 24 trials per day for five consecutive afternoons were given. The microswitch was depressed after a warning light and a foreperiod activated an audio response stimulus. A significant difference in RT was not found between subjects with epilepsy and those without epilepsy within each intellectual classification.
