Peripheral Flicker Fusion at High Luminance: Beyond the Ferry–Porter Law

open access: yesVision, 2023
The relationship between luminous intensity and the maximum frequency of flicker that can be detected defines the limits of the temporal-resolving ability of the human visual system, and characterizing it has important theoretical and practical ...

Two Visual Training Paradigms Associated with Enhanced Critical Flicker Fusion Threshold

open access: yesFrontiers in Psychology, 2016
Critical flicker fusion thresholds (CFFT) describe when quick amplitude modulations of a light source become undetectable as the frequency of the modulation increases and are thought to underlie a number of visual processing skills, including reading ...
