Visual experience can substantially alter critical flicker fusion thresholds.
Studies of psychopharmacology often use the test of the critical flicker fusion (CFF) threshold as a measure of total information processing. It is true that studies of practice effects have shown that CFF thresholds are remarkably stable within and across multiple days of testing. This study confirms that subjects who undergo CFF testing on sequential days have stable thresholds, but also demo...
متن کاملDorsal stream contributions to perceptual asymmetries.
Neurologically normal individuals show a bias toward the left side of space, referred to as pseudoneglect due to its similarity to clinical hemispatial neglect. The left bias appears to be stronger in the lower visual field during free-viewing, which could result from preferential dorsal stream processing. The current experiments used modified greyscales tasks, incorporating motion and isolumin...
متن کاملCritical flicker fusion test of potential vision.
PURPOSE To continue developing a potential vision test based on the critical flicker fusion (CFF) phenomenon by using a brighter stimulus and optimizing its size. SETTING Flinders Eye Centre, Flinders Medical Centre, Flinders University, Bedford Park, South Australia, Australia. METHODS In a prospective nonrandomized study, 225 participants were assigned to 1 of 4 groups: normal, media opac...
متن کاملPerceptual Learning of Motion Leads to Faster Flicker Perception
Critical flicker fusion thresholds (CFFT) describe when quick amplitude modulations of a light source become undetectable as the frequency of the modulation increases. The threshold at which CFF occurs has been shown to remain constant under repeated testing. Additionally, CFF thresholds are correlated with various measures of intelligence, and have been regarded by clinicians as a general meas...
متن کاملBilingualism’s Influence on Perceptual Learning of Word Decoding and Flicker Fusion
Language acquisition is a unique human trait that has evolved into the most efficient communication system known. Individuals with normal linguistic physical structures who are exposed to speech acquire language in an almost effortless manner during early development. Individuals who learn to speak one language are referred to as monolinguals. Individuals exposed to multiple languages on a regu...
