Does contrast sensitivity decline with age, and if so, to what extent?
Best insight from top research papers
Contrast sensitivity does decline with age, and the extent of the decline varies depending on the specific factors being measured. One study found that older adults had lower calculation efficiencies in motion contrast sensitivity, but no significant aging effect was found on temporal modulation transfer function, early noise, and late noise . Another study found that the sensitivity of the younger age group was higher than that of the older age group by 0.3 log units on average, and the decline in sensitivity for medium to high spatial frequencies at high photopic light levels was relatively larger in the older age group . Additionally, a psychophysical study revealed that aging impacts both internal additive noise and perceptual template gain, and this age-related degradation is tuned to spatial frequency . Overall, these findings suggest that contrast sensitivity does decline with age, but the extent of the decline depends on various factors such as the specific aspect of contrast sensitivity being measured and the spatial frequency being tested.

Is high or low contrast easier to read?5 answersHigh contrast is generally easier to read compared to low contrast. Research indicates that contrast sensitivity plays a crucial role in text accessibility, with high-contrast formats like black laser print on white paper significantly increasing readability. Furthermore, studies on color contrast in information design show that high luminance contrast, such as in a Red-Green-Blue graph, is perceived as more useful for complex tasks involving multiple lines. Contrast sensitivity is highlighted as an essential visual parameter, often overlooked in routine eye examinations due to time constraints. The ability to differentiate between high and low contrast is crucial for tasks involving text comprehension and visual perception, emphasizing the importance of high contrast for improved readability and task performance.
Is there a difference in pupil dilation depending on age?5 answersPupil dilation varies depending on age. Older adults show greater pupil dilation during reappraisal (approach) strategies compared to distraction (avoidance) strategies, while younger adults show no difference between the two strategies. Medical studies have shown that average pupil size decreases linearly throughout adult life, resulting in larger differences in dilation between two images acquired at different times. In a study evaluating pupillometry values in different age groups, it was found that pupil diameter is significantly larger in children compared to adults, and the mean pupil dilation speed is highest in children. Another study analyzing dilation in children over time found that dilation variation can impact iris recognition performance. Therefore, age is a factor that influences pupil dilation, with older adults and children showing different patterns of dilation compared to younger adults.
Do Visual difference predictors use contrast sensitivity functions and if so how?5 answersVisual difference predictors do use contrast sensitivity functions (CSFs) in their analysis. Different studies have explored the relevance of CSFs in understanding human vision and developing models for low-level visual tasks. One study found that a simple optical device could be used to measure CSF and compare it with a computer-based system. Another study used convolutional neural networks (CNNs) to develop human-like CSFs by training them on basic low-level vision tasks. Additionally, a framework was established to predict individual CSFs using a zero-parameter model that shifts a standard-shaped template CSF based on measurements of high contrast acuity and letter contrast sensitivity. Another study showed that artificial neural networks (ANNs) trained on low-level visual tasks can develop human-like CSFs, but the optimization process and architecture of the ANN can affect the accuracy of the CSFs. Finally, a Bayesian framework was proposed to estimate CSF parameters from experimental data, improving the accuracy and precision of parameter estimates.
Are there age effects in emotionrecognition?4 answersAge effects in emotion recognition have been investigated using various stimuli and tasks. Several studies have found that younger adults generally have higher overall recognition rates than older adults. Age-related decline in emotion recognition ability may be partly influenced by cognitive and affective factors such as processing speed, fluid intelligence, and depression. Older adults tend to have greater difficulties recognizing certain emotions, particularly anger, fear, and sadness, compared to happiness and surprise. However, the magnitude and direction of age effects can be influenced by task characteristics, such as the use of videos, which may reduce the age-related positivity effect in facial emotion recognition. Additionally, age-related decline in emotion processing may be associated with changes in neural connectivity, particularly for negative emotions. Overall, age effects in emotion recognition are influenced by various factors and can vary depending on the specific emotions and tasks involved.
When was the contrast media use fisrt?3 answersContrast media use was first introduced in the 1920s and 1930s with the development of iodine-based contrast media, which allowed radiologists to visualize vessels and organs on imaging studies. However, these early contrast media had some degree of toxicity. Since then, research has been conducted to improve the safety and efficacy of contrast media. In the field of diagnostic radiology, contrast media are used to enhance the X-ray attenuation between a body structure of interest and the surrounding tissue, thereby making details perceptible on radiographs. The use of gadolinium-based contrast media in CNS MR imaging was introduced later and has become routine for improving the sensitivity and specificity of CNS diseases, as well as for measuring tissue perfusion and following the time course of enhancement in dynamic imaging studies.
When is contrast not needed for cardiac MRI?5 answersContrast is not needed for cardiac MRI in certain situations. Noncontrast 3D MRI techniques are desirable for serial imaging in patients with congenital heart disease (CHD). Native T1 mapping can differentiate between different hereditary cardiomyopathies without the use of contrast material. Noncontrast alternatives are emerging for tissue characterization in ischemic and nonischemic cardiomyopathy, such as native T1 mapping, stress perfusion imaging, and stress wall motion imaging. Pre-contrast CMR images can be used to predict post-contrast information, eliminating the need for contrast agents in visualizing and quantifying myocardial infarction. Non-contrast MT-based tissue characterization can be applied in end-stage renal disease (ESRD) patients, who are contraindicated to standard gadolinium-based fibrosis imaging.
