El objetivo del presente estudio es investigar el efecto de la ansiedad y el tiempo de reacción en estudiantes de la Universidad de Tabriz. Participaron 48 estudiantes (24 mujeres y 24 hombres) de Educación Física de la Universidad de Tabriz. Los estudiantes fueron evaluados mediante el cuestionario de escala de Spielberger y la prueba del tiempo de reacción para determinar el nivel de ansiedad. El muestreo se realizó de manera aleatoria en estudiantes de Educación Física de la Universidad de Tabriz, con una edad de 22 ± 3 años. Después de comprobar la normalidad de los datos, a través del análisis de varianza, se analizaron dos factores (ansiedad y tiempo de reacción) en cada grupo para cada una de las variables individualmente. Los resultados indicaron que hubo una relación negativa entre la ansiedad-estado y el tiempo de reacción de las manos (r = 0.112, p = 0.398) y entre la ansiedad-rasgo y el tiempo de reacción simple de los pies (r = 0.209, p = 0.154). Además, hubo una relación positiva entre la ansiedad-estado y el tiempo de reacción simple de los pies (p = 0.0625, r = -0.072) y entre la ansiedad-rasgo y el tiempo de reacción de las manos (p = 0.874, r = -0.024). Los resultados de este estudio respaldan la hipótesis de la U invertida. The objective of the present study is to investigate the effect of anxiety and reaction time in students of the University of Tabriz. 24 female and 24 male physical education students of Tabriz University responded to the Spielberger Scale Questionnaire and the Reaction Time Test to determine the level of anxiety. Sampling was conducted randomly from physical education students of Tabriz University with the age 22 ± 3. After ensuring that the data were normal, through the variance analysis, two in-group factors of anxiety and reaction time were analyzed for each of the variables individually. The results indicated that there was a negative relationship between state anxiety and choice reaction time of hands (r = 0.112, p = 0.398) and between trait anxiety and simple reaction time of feet (r = 0.209, p = 0.154). In addition, there was a positive relationship between state anxiety and simple reaction time of feet (p = 0.0625, r = -0.072) and between trait anxiety and choice reaction time of hands (p = 0.874, r = -0.024). The results of this study support the Inverted U hypothesis.

Decision Choice

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.

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.

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.

  Introducción: Diversos estudios relacionan variables como la edad, sexo, nivel socioeconómico, religión, etc. con los niveles de homofobia y transfobia. El objetivo de la presente investigación fue determinar la incidencia de algunas variables sociodemográficas y de los conocimientos biológicos sobre la homosexualidad y transexualidad sobre los niveles de homofobia y transfobia en estudiantes de Educación Física de Chile. Método: se aplicó una encuesta sociodemográfica, la escala de homofobia EHF-10, la escala de actitudes negativas hacia personas trans y el cuestionario de conocimientos biológicos de la homosexualidad y transexualidad a 463 estudiantes de Pedagogía en Educación Física de seis universidades de Chile. Resultados: los niveles de homofobia y transfobia son bajos en la muestra, siendo la convivencia con amigos/as o conocidos/as homosexuales, bisexuales y trans, y las creencias religiosas los factores que más inciden en dichas actitudes negativas. Se observó una relación negativa y baja entre conocimientos biológicos de homosexualidad y transexualidad y los niveles de homofobia y transfobia. Conclusión: la muestra presenta bajos niveles de homofobia y transfobia. También se observan bajos valores de conocimientos biológicos de la homosexualidad y transexualidad, con una relación baja y negativa entre dichos conocimientos y las actitudes negativas hacia personas homosexuales y trans.  Abstract. Introduction: Various studies relate variables such as age, sex, socioeconomic level, religion, etc. with levels of homophobia and transphobia. The aim of this research is to determine the incidence of some sociodemographic variables and biological knowledge about homosexuality and transsexuality on the levels of homophobia and transphobia in physical education students in Chile. Method: a sociodemographic survey was applied, the scale of homophobia EHF-10, the scale of negative attitudes towards trans people and the questionnaire of biological knowledge of homosexuality and transsexuality to 463 students of Pedagogy in Physical Education from six universities in Chile. Results: The levels of homophobia and transphobia are low in the sample, being the coexistence with friends/ or known/ homosexual, bisexual and trans, and the religious beliefs the factors that most affect those negative attitudes. A negative and low relationship was observed between biological knowledge of homosexuality and transsexuality and levels of homophobia and transphobia. Conclusion: The sample has low levels of homophobia and transphobia. There are also low biological knowledge values of homosexuality and transsexuality, with a low and negative relationship between such knowledge and negative attitudes towards homosexuals and transgender people.
