There are significant gaps in understanding the extent of damage caused by COVID-19, with few publications examining its link to contrast sensitivity function (CSF). The aim present study was evaluate CSF at low, medium, and high spatial frequencies individuals without a history COVID-19. Thirty adults, both male female, aged between 18 49 years, participated study, 15 COVID-19 without. measured using Metropsis software (version 11) vertical sine-wave gratings ranging from 0.2 19.8 cycles...
Objectives: The present study evaluated early visual processing, in terms of the contrast sensitivity function (CSF), bipolar disorder (BPD) patients.Methods: Data were recorded 17 healthy participants and outpatients with type 1 BPD, from 20 to 45 years age. CSF was measured at spatial frequencies 0.2, 0.6, 3.1, 8.0, 16.0 20.0 cycles per degree (cpd) using Gabor patches a two-alternative, forced-choice, logarithmic staircase method. groups matched for gender, age level education.Results:...
This study evaluated reproducibility of the Trivector subtest Cambridge Colour Test. Data for normal trichromats were obtained in Brazil ($ N = 111 $N=111) at T0, six months (T1), and 12 later (T2), United Kingdom (${ N}={79}$N=79), with test directly followed by a retest. Coefficients repeatability-Bland-Altman indices-for Protan, Deutan, Tritan vectors similar both datasets. Intraclass correlation coefficients (ICCs)-measures reliability-were low or moderate these relatively homogeneous...
Objective: Chronic tobacco consumption, classified as use disorder (TUD), has been associated with a variety of health problems. Investigations face processing in TUD are hampered by lack evidence. Here, we evaluated facial detection and assessed test-retest reliability for task. Methods: Participants were instructed to detect the orientation (either left or right) when it was presented face/non-face pair on monitor screen, using Bayesian entropy estimation. Bland-Altman analysis intraclass...
Objective: The main purpose of this study was to investigate short-term effects nicotine gum on facial detection. Methods: Fourteen participants (mean age = 26.8 years, SD 2.5 years; eight males) were enrolled in pilot randomized controlled trial administration (placebo, 2-mg and 4-mg doses). instructed detect the location a face when it presented face/nonface pair screen. A repeated multivariate analysis variance conducted analyze results for reaction time discrimination index. Demographics...
Patients with schizophrenia have visual processing impairments. The main findings from the literature indicate that these deficits may be related to differences in paradigms, medications, and illness duration. This study is part of a large-scale investigating sensitivity schizophrenia. Here we aimed investigate combined effects duration antipsychotic use on contrast function.Data were collected 50 healthy controls outpatients (classified according medication type) aged 20-45 years old....
Background : increasing interest in visual disturbances schizophrenia is connected with the fact that they are a potential biomarker for objectification of mental condition. The nature relationship between and higher-level cognitive functions remains understudied. aim study was to investigate differences information processing individuals paranoid healthy individuals, analyze system characteristics clinical factors. Patients methods thirty-three patients form 19 subjects were included...
Background: Although some studies have shown impairments in patients with bipolar disorder (BPD) and smokers, it is unclear how these two factors work together. Our premise was that chronic smoking affects color discrimination this more pronounced BPD. Objective: main purpose to investigate the influence of BPD on discrimination. Methods: Twenty-three smokers 23 patients, aged 25–45 years old, participated study. Color vision testing performed using Trivector subtest Cambridge Colour Test....
Objectives: The effects of smoking on color vision have been scarcely studied. To bridge such gap, this study examined if there were differences in chromatic discrimination between heavy and light smokers. Methods: psychophysical Trivector test was used to evaluate healthy controls (n = 36), smokers 29), 32). subject's task identify the orientation Landolt C ring gap – presented randomized one four positions (e.g., up, down, right, left). Results: thresholds for Protan (red), Deutan (green)...
Chronic tobacco consumption, identified as Tobacco Use Disorder (TUD), is a public health problem. We present case report of 37-year-old Brazilian male diagnosed with TUD at age 26, no comorbidities, that presented visual improvements (i.e., lower thresholds and better discrimination) after nicotine gum administration. Here, we assessed contrast sensitivity chromatic discrimination using the Metropsis Cambridge Colour Test, respectively. Results showed for both tasks use gum. Even...
High levels of cognitive load have a disruptive effect on many tasks, especially driving. Surprisingly, we know little about the (if any) immediately before driving, and even less driving (with its own load) subsequent performance in tasks. The was examined Study 1. Participants completed tests with low or moderate (LCL vs MCL) simulated task. Their speed, distance from car ahead, lane keeping abilities were assessed two consecutive days. 2 demanding (as task own) accuracy reaction time to...
Abstract Our past anecdotal evidence prompted that a longer response window (RW) in the Trivector test (Cambridge Colour Test) improved mature observers’ estimates of chromatic discrimination. Here, we systematically explored whether RW variation affects discrimination thresholds measured by length Protan, Deutan and Tritan vectors. We employed with three RWs: 3 s, 5 8 s. Data 30 healthy normal trichromats were stratified as age groups: ‘young’ (20–29 years), ‘middle-aged’ (31–48 ‘mature’...
